授权日期: 2017-11-10
治疗区: 止血、手术
在标准外科技术不足的成年人中给予支持治疗:
-改善止血。
-作为血管外科的缝合支架
VeraSeal 是一种用于在手术中止血或在血管手术中支持缝线的密封胶 (胶水)。
当标准手术技术工作不够好时, VeraSeal 就会被使用。它含有人体纤维蛋白原和人凝血酶的活性物质。
VeraSeal 只应由受过训练的有经验的外科医生使用。它可以作为两个预先填入注射器在一个注射器持有人, 一个含有人类纤维蛋白原的解决方案 (80 毫克/毫升), 另一个含有人类凝血酶 (500 国际单位/毫升) 的解决方案。在使用之前, 注射器被连接到一个设备提供的药物, 允许他们的内容混合, 因为他们被滴或喷洒在伤口上。使用的 VeraSeal 量取决于多种因素, 包括手术类型、伤口大小和应用数量。
VeraSeal 如何工作?
VeraSeal、纤维蛋白原和凝血酶中的活性物质是人体血浆 (血液中的液体部分) 中存在的物质, 参与正常的凝血过程。
当两种活性物质混合时, 凝血酶会将纤维蛋白原切割成纤维蛋白。纤维蛋白然后聚集 (粘在一起), 形成一个纤维蛋白凝块, 帮助伤口愈合, 防止出血。
VeraSeal 在研究中表现出哪些好处?
三项主要研究在614例发现, VeraSeal 是有效的止血在4分钟内应用它在手术期间。
在一项关于血管手术的研究中, VeraSeal 比手工压缩效果好, 76% 的患者在治疗后4分钟内没有出血 (83 109), 与人工压缩后的23% 相比 (13 出 57)。
在第二项器官外科研究中, VeraSeal 与另一种产品 Surgicel: 93% 的患者在治疗后4分钟内没有出血 (103 111), 而81% 的患者没有出血与 Surgicel (91 出 113)。
最后, 在对软组织手术进行的第三项研究中, VeraSeal 与 Surgicel 一样有效: 83% 的患者在治疗后4分钟内没有出血 (96 116), 与 Surgicel 治疗后78% 例比较 (84 出 108)。
与 VeraSeal 相关的风险有哪些?
最共同的副作用与 VeraSeal (可能影响1在10个人) 是恶心 (感觉不适), 瘙痒 (发痒) 和程序性痛苦 (痛苦从手术)。很少, VeraSeal 可能导致过敏反应, 这可能是严重的, 特别是当药物被反复使用。在罕见的情况下, 患者已经开发出抗体的蛋白质在 VeraSeal, 这可能会干扰血液凝固。如果 VeraSeal 被意外注入血管, 血栓栓塞并发症 (血块) 可能发生。当这种密封剂被应用于喷雾时, 发生气体栓塞 (阻塞血流的气泡) 的情况。
VeraSeal 不能使用 intravascularly (血管内) 或治疗大出血的动脉。VeraSeal 在内窥镜下不能应用 (使用导管在体内进行观察的过程)。
有关 VeraSeal 的所有副作用和限制的完整列表, 请参阅包装单张。
为什么 VeraSeal 批准?
VeraSeal 已被证明可以有效止血在手术中, 这有望减少失血, 减少在手术室的时间, 并可能缩短医院停留。虽然病人可能会对药物产生抗体, 这可能会降低它的功效, 但在研究中却没有发现这一点。
对于从血液中获得的所有药物, 感染可以用药物传播;然而, 这种药物是使用过滤和一个过程来灭活病毒, 以减少这种风险。观察到的副作用与主要手术或病人的病情预期相同。因此, 欧洲医药机构决定, VeraSeal 的利益大于风险, 并建议批准它在欧盟使用。
正在采取哪些措施来确保安全和有效地使用 VeraSeal?

ANNEX I
SUMMARY OF PRODUCT CHARACTERISTICS
1
This medicinal product is subject to additional monitoring. This will allow quick identification of new safety information. Healthcare professionals are asked to report any suspected adverse reactions. See section 4.8 for how to report adverse reactions.
1. NAME OF THE MEDICINAL PRODUCT
VeraSeal solutions for sealant
2. QUALITATIVE AND QUANTITATIVE COMPOSITION
Component 1:
Human fibrinogen 80 mg/ml
Component 2:
Human thrombin 500 IU/ml
Produced from the plasma of human donors.
For the full list of excipients, see section 6.1.
3. PHARMACEUTICAL FORM
Solutions for sealant.
Frozen solutions. After thawing, the solutions are clear or slightly opalescent and colourless or pale yellow.
4. CLINICAL PARTICULARS 4.1 Therapeutic indications
Supportive treatment in adults where standard surgical techniques are insufficient:
- for improvement of haemostasis.
- as suture support: in vascular surgery.
4.2 Posology and method of administration
The use of VeraSeal is restricted to experienced surgeons who have been trained in the use of this medicinal product.
Posology
The volume of VeraSeal to be applied and the frequency of application should always be oriented towards the underlying clinical needs for the patient.
The dose to be applied is governed by variables including, but not limited to, the type of surgical intervention, the size of the area and the mode of intended application, and the number of applications.
Application of the product must be individualised by the treating physician. In clinical trials, the individual dosages have typically ranged from 0.3 to 12 ml. For other procedures, larger volumes may be required.
2
The initial volume of the product to be applied at a chosen anatomic site or target surface area should be sufficient to entirely cover the intended application area. The application can be repeated, if necessary.
Paediatric population
The safety and efficacy of VeraSeal in children aged 0 to 18 years has not yet been established. Currently available data are described in section 5.1, but no recommendation on a posology can be made.
Method of administration
For epilesional use.
For instructions on preparation of the medicinal product before administration, see section 6.6. The product should only be administered according to the instructions and with the devices recommended for this product (see section 6.6.).
Prior to applying VeraSeal, the surface area of the wound needs to be dried by standard techniques (e.g. intermittent application of compresses, swabs, use of suction devices).
To avoid the risk of potentially life-threatening air or gas embolism, VeraSeal is recommended to be sprayed using pressurised CO2.
For spray application, see sections 4.4 and 6.6 for specific recommendations on the required pressure and distance from tissue per surgical procedure.
4.3 Contraindications
VeraSeal must not be applied intravascularly.
Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.
VeraSeal must not be used for the treatment of severe or brisk arterial bleeding.
Spray application of VeraSeal must not be used in endoscopic procedures. For laparoscopy, see section 4.4.
4.4 Special warnings and precautions for use
Precautions for use
For epilesional use only. Do not apply intravascularly.
Life threatening thromboembolic complications may occur if the preparation is unintentionally applied intravascularly (see section 4.8).
Life-threatening air or gas embolism has occurred with the use of spray devices employing a pressure regulator to administer fibrin sealant products. This event appears to be related to the use of the spray device at higher than recommended pressures and/or in close proximity to the tissue surface.
The risk appears to be higher when fibrin sealants are sprayed with air, as compared to CO2 and, therefore, cannot be excluded with VeraSeal. To minimize this risk, the spray device should be operated according to the instructions provided in section 6.6.
VeraSeal spray application should only be used if it is possible to accurately judge the spray distance, especially during laparoscopy. Spray distance from tissue and pressure should be within the ranges
3
recommended by the marketing authorisation holder of VeraSeal (see table in section 6.6 for pressure and distance).
When spraying VeraSeal, changes in blood pressure, pulse, oxygen saturation and end tidal CO2 should be monitored because of the possibility of occurrence of air or gas embolism.
When using accessory tips, the instructions for use of the tips should be followed.
Before administration of VeraSeal, care must be taken that the parts of the body outside the desired application area are sufficiently protected (covered) to prevent tissue adhesion at undesired sites.
VeraSeal should be applied as a thin layer. Excessive clot thickness may negatively interfere with the product’s efficacy and the wound healing process.
Adequate data are not available to support the use of this product in tissue gluing, neurosurgery, application through a flexible endoscope for treatment of bleeding or in gastrointestinal anastomoses.
Hypersensitivity reactions
As with any protein product, allergic type hypersensitivity reactions are possible. Signs of hypersensitivity reactions include hives, generalised urticaria, tightness of the chest, wheezing, hypotension, and anaphylaxis. If these symptoms occur, the administration must be discontinued immediately. In case of shock, standard medical treatment for shock should be implemented.
Transmissible agents
Standard measures to prevent infections resulting from the use of medicinal products prepared from human blood or plasma include selection of donors, screening of individual donations and plasma pools for specific markers of infection and the inclusion of effective manufacturing steps for the inactivation /removal of viruses. Despite this, when medicinal products prepared from human blood or plasma are administered, the possibility of transmitting infective agents cannot be totally excluded. This also applies to unknown or emerging viruses and other pathogens.
The measures taken are considered effective for enveloped viruses such as human immunodeficiency virus (HIV), hepatitis B virus and hepatitis C virus, and for the non-enveloped hepatitis A virus. The measures taken may be of limited value against non-enveloped viruses such as parvovirus B19.
Parvovirus B19 infection may be serious for pregnant women (foetal infection) and for individuals with immunodeficiency or increased erythropoiesis (e.g. haemolytic anaemia).
Traceability
It is strongly recommended that every time that VeraSeal is administered to a patient, the name and batch number of the product are recorded to maintain a link between the patient and the batch of the product.
4.5 Interaction with other medicinal products and other forms of interaction
No formal interaction studies have been performed. Similar to comparable products or thrombin solutions, the product may be denatured after exposure to solutions containing alcohol, iodine or heavy metals (e.g. antiseptic solutions). Such substances should be removed to the greatest possible extent before applying the product.

4.6 Fertility, pregnancy and lactation
Pregnancy and breast-feeding
The safety of fibrin sealant/haemostatic products for use in human pregnancy or breast-feeding has not been established in controlled clinical trials. Experimental animal studies are insufficient to assess the safety with respect to reproduction, development of the embryo or foetus, the course of gestation and peri- and post-natal development. Therefore, the product should be administered to pregnant and breast-feeding women only if clearly needed.
Fertility
Fertility studies have not been conducted.
4.7 Effects on ability to drive and use machines
Not relevant.
4.8 Undesirable effects
Summary of the safety profile
Hypersensitivity or allergic reactions (which may include angioedema, burning and stinging at the application site, bronchospasm, chills, flushing, generalised urticaria, headache, hives, hypotension, lethargy, nausea, restlessness, tachycardia, tightness of the chest, tingling, vomiting, wheezing) may occur in rare cases in patients treated with fibrin sealant/haemostatic products. In isolated cases, these reactions have progressed to severe anaphylaxis. Such reactions may especially be seen, if the preparation is applied repeatedly, or administered to patients known to be hypersensitive to constituents of the product.
Antibodies against components of fibrin sealant/haemostatic products may occur rarely.
Inadvertent intravascular injection could lead to thromboembolic event and disseminated intravascular coagulation (DIC), and there is also a risk of anaphylactic reaction (see section 4.4).
Life-threatening air or gas embolism has occurred with the use of spray devices employing a pressure regulator to administer fibrin sealant/haemostatic products. This event appears to be related to the use of the spray device at higher than recommended pressures and/or near the tissue surface.
For safety information with respect to transmissible agents, see section 4.4.

|
|
|
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the national reporting system listed in Appendix V.
4.9 Overdose
In the event of overdose, patients must be closely monitored for signs or symptoms of adverse reactions and appropriate symptomatic treatment and supportive measures instituted.
5. PHARMACOLOGICAL PROPERTIES 5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Antihaemorrhagics, local hemostatics, ATC code: B02BC Mechanism of action
The fibrin adhesion system initiates the last phase of physiological blood coagulation. Conversion of fibrinogen into fibrin occurs by the splitting of fibrinogen into fibrin monomers and fibrinopeptides. The fibrin monomers aggregate and form a fibrin clot. Factor XIIIa, which is activated from factor XIII by thrombin, crosslinks fibrin. Calcium ions are required for both, the conversion of fibrinogen and the crosslinkage of fibrin.
As wound healing progresses, increased fibrinolytic activity is induced by plasmin and decomposition of fibrin to fibrin degradation products is initiated.
Clinical efficacy and safety
Randomized, single-blind clinical studies with VeraSeal were conducted in subjects undergoing vascular, parenchymous tissue and soft tissue surgery demonstrating haemostasis, and suture support in vascular surgery.
During the vascular surgery study 225 subjects were enrolled and underwent vascular surgical procedures utilizing polytetrafluoroethylene graft material on end-to-side arterial anastomosis or on upper extremity vascular access arterial anastomosis. The mean age of the study population and its standard deviation was 63.2 (9.5) years. The most frequent surgery types were femoral-popliteal bypass grafting, upper extremity vascular access for hemodialysis, and ilio-femoral bypass grafting.
7
VeraSeal was shown to be superior to the control group (manual compression) in achieving hemostasis by 4 minutes. The rate of hemostasis at the target bleeding site by 4 minutes was 76.1% in the VeraSeal treatment group and was 22.8% in the control group.
During parenchymous tissue surgery study 325 subjects were enrolled and underwent liver resections. The mean age of the study population and its standard deviation was 57.9 (14.5) years. VeraSeal was shown to be superior to the control group (oxidized regenerated cellulose) in achieving hemostasis by 4 minutes. The rate of hemostasis at the target bleeding site by 4 minutes was 92.8% in the VeraSeal treatment group and was 80.5% in the control group.
During soft tissue surgery study 327 subjects were enrolled and underwent pelvic and retroperitoneal surgical procedures, and abdominoplasties and mastopexies. The mean age of the study population and its standard deviation was 47.2 (18.4) years. The most frequent surgery types were simple or radical hysterectomies, abdominoplasties, and radical cystectomies. VeraSeal was shown to be non-inferior to the control group (oxidized regenerated cellulose) in achieving hemostasis by 4 minutes. The rate of hemostasis at the target bleeding site by 4 minutes was 82.8% in the VeraSeal treatment group and was 77.8% in the control group.
Paediatric population
Eleven paediatric subjects aged 16 years or younger were treated with VeraSeal in the described clinical studies.
The European Medicines Agency has deferred the obligation to submit the results of studies with VeraSeal in one or more subsets of the paediatric population for the treatment of haemorrhage resulting from a surgical procedure as per Paediatric Investigational Plan (PIP) decision, for the granted indication (see section 4.2 for information on paediatric use).
5.2 Pharmacokinetic properties
VeraSeal is intended for epilesional use only. Intravascular administration is contraindicated.
Consequently, intravascular pharmacokinetic studies were not performed in man.
Fibrin sealant/haemostatic products are metabolised in the same way as endogenous fibrin by fibrinolysis and phagocytosis.
5.3 Preclinical safety data
Non-clinical data reveal no special hazard for humans based on conventional studies of safety pharmacology and acute toxicity.

6.6 Special precautions for disposal and other handling
The instructions for use are also described in the healthcare professionals’ package leaflet part.
• Thawing
Room temperature thawing
VeraSeal should be thawed at room temperature (20 ºC - 25 ºC) for approximately eighty (80) minutes for the 2 ml and the 4 ml presentations and one hundred twenty (120) minutes for the
6 ml and the 10 ml presentations. The steps required for thawing are:
- Open the cardboard case and take out the inner contents.
- Place this packaging on a surface at room temperature.
After thawing, it is not necessary to warm the product for its use.
Water bath
In case thawing times need to be shortened, a thermostatic water-bath could be used, but always at a temperature not higher than 37 ºC. At 37 ºC the times needed are approximately
twenty (20) minutes for the 2 ml and the 4 ml presentations and thirty (30) minutes for the 6 ml and the 10 ml presentations. The steps required for thawing are:
- Open the cardboard case and take out the inner contents.
- Place this packaging into water bath.
- Ensure this packaging remains submerged throughout thawing.
The temperature must not exceed 37 ºC.
• Preparation
After thawing the solutions must be clear to slightly opalescent and colourless to pale yellow. Solutions that are cloudy or have deposits should not be used.
Transferring operations include:
- Remove the packaging from surface at room temperature, from the refrigerator at 2 °C - 8 °C or from the water bath (and dry the outer pouch) after thawing.
- Open the outer pouch and remove the sterile inner blister.
- Open the inner blister and make the VeraSeal syringe holder available to a second person for transfer to the sterile field. The outside of the blister package should not come in contact with the sterile field.
Connection operations include:
- Hold the VeraSeal syringe holder slightly inclined upwards.
- Unscrew and remove the tip cap of both fibrinogen and thrombin syringes.
- To remove air bubbles from syringes, strike gently the side of the syringes one or two times while keeping the syringe holder in an upright position and eject air.
- To attach the applicator tip, screw both syringes consecutively, making a quarter (90 degree) turn each time.

• Application by dripping
VeraSeal must be applied with the syringe holder supplied.
VeraSeal must be applied with the cannula provided with the product, or an equivalent CE-marked cannula (including open surgery and laparoscopic use devices) intended for that use. When using the provided cannula, follow the connection instructions described above. When using other applicator tips, the instructions for use of the tips should be followed.
When dripped, the tip of the applicator should be kept as close as possible to the tissue surface, but without touching the tissue during application. Individual drops should be applied to the area to be treated.
To prevent uncontrolled clotting, the drops should be allowed to separate from each other and from the tip of the applicator.
• Application by spraying
VeraSeal must be applied with the syringe holder provided. VeraSeal should only be applied if it is possible to accurately judge the spray distance (see also section 4.4).
VeraSeal must be applied with the spray device that is supplied separately, or an equivalent CE-marked spray device (including open surgery and laparoscopic use devices) intended for that use. Always refer to the specific instructions provided with the device packages.
To avoid the risk of potentially life-threatening air or gas embolism VeraSeal is recommended to be sprayed using pressurised CO2 (see table below).
Connect the short gas tube on the application device to the luer-lock end of the filter tubing. Then connect the luer-lock of the gas tube to a pressure regulator capable of delivering
15 - 25 psi (1.0 - 1.7 bar) of gas pressure. The pressure regulator should be used in accordance with the manufacturer’s instructions.
When applying VeraSeal using a spray device, it has to be ensured that the pressure and the distance from the tissue are within the ranges recommended by the marketing authorisation holder of VeraSeal, as given in the following table:

Package leaflet: Information for the user
VeraSeal solutions for sealant
human fibrinogen/human thrombin
This medicine is subject to additional monitoring. This will allow quick identification of new safety information. You can help by reporting any side effects you may get. See the end of section 4 for how to report side effects.
Read all of this leaflet carefully before you start using this medicine because it contains important information for you.
- Keep this leaflet. You may need to read it again.
- If you have any further questions, ask your doctor.
- If you get any side effects, talk to your doctor. This includes any possible side effects not listed in this leaflet. See section 4.
What is in this leaflet
1. What VeraSeal is and what it is used for
2. What you need to know before you are treated with VeraSeal
3. How VeraSeal is used
4. Possible side effects
5. How VeraSeal is stored
6. Contents of the pack and other information
1. What VeraSeal is and what it is used for
VeraSeal contains human fibrinogen and human thrombin, two proteins extracted from the blood that form a clot when they are mixed together.
VeraSeal is used as a sealant during surgical operations in adults. It is applied to the surface of bleeding tissue to reduce bleeding during and after the operation when standard surgical techniques are not sufficient.
2. What you need to know before you are treated with VeraSeal Your surgeon must not treat you with VeraSeal:
- if you are allergic to human fibrinogen or human thrombin or any of the other ingredients of this medicine (listed in section 6).
VeraSeal must not be applied inside blood vessels.
VeraSeal must not be used to treat severe or rapid bleeding from an artery.
VeraSeal must not be used by spraying in surgery carried out internally using an endoscope (a long flexible instrument for probing inside the body). For keyhole surgery (laparoscopy), the doctor will only use VeraSeal by spraying if the distance of the spray can be accurately judged (see below).
Warnings and precautions
Allergic reactions are possible. Signs of such reactions include hives, rash, tightness of the chest, wheezing, drop in blood pressure (e.g. light-headedness, fainting, blurred vision), and anaphylaxis (a
26
severe reaction with a rapid onset). If these symptoms occur during surgery, the use of the medicine should be stopped immediately.
Life-threatening air or gas embolism has occurred with the use of spray devices employing a pressure regulator to administer fibrin sealant products. This event occurs when air or gas bubbles enter a vein or artery and block it. This event appears to be related to the use of the spray device at higher than recommended pressures and/or near the tissue surface.
The risk appears to be higher when fibrin sealants are sprayed with air, as compared to CO2 and therefore cannot be excluded with VeraSeal. To minimize this risk, your surgeon will operate the spray device according to the instructions provided at the end of this leaflet.
VeraSeal spray application should only be used if it is possible to accurately judge the spray distance. A defined pressure within the range recommended should be used. In addition, the spray device should not be used closer than the recommended distance. When spraying VeraSeal, specific vitals will be monitored because of the possibility of occurrence of gas embolism. .
Special safety warning
For medicines such as VeraSeal that are made from human blood or plasma, certain measures are taken to prevent infections being passed on to patients. These include carefully selecting blood and plasma donors to make sure those at risk of carrying infections are excluded, and testing each donation and pooled plasma for signs of virus/infections. Manufacturers also include steps in the processing of the blood or plasma that can inactivate or remove viruses. Despite these measures, when medicines prepared from human blood or plasma are administered, the possibility of passing on infection cannot be totally excluded. This also applies to any unknown or emerging viruses or other types of infections.
The measures taken are considered effective for enveloped viruses such as human immunodeficiency virus (HIV), hepatitis B virus and hepatitis C virus, and for the non-enveloped hepatitis A virus. The measures taken may be of limited value against non-enveloped viruses such as parvovirus B19.
Parvovirus B19 infection may be serious for pregnant women (fetal infection) and for individuals whose immune system is depressed or who have some types of anaemia (e.g. sickle cell disease or haemolytic anaemia).
It is strongly recommended that every time you are treated with VeraSeal, the name and batch number of the medicine are recorded in order to maintain a record of the batches used.
Children and adolescents
VeraSeal is not recommended for use in children and adolescents under 18 years of age.
Other medicines and VeraSeal
The product may be affected after contacting solutions containing alcohol, iodine or heavy metals (e.g.
antiseptic solutions).
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
Pregnancy and breast-feeding
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before being treated with this medicine. Your doctor will decide whether you should be treated with VeraSeal.
27
3. How VeraSeal is used
The use of VeraSeal is restricted to experienced surgeons who have been trained in the use of VeraSeal.
The surgeon will apply VeraSeal to the surface of blood vessels or to the tissue surface of internal organs using an application device during the course of the operation. This device allows equal amounts of the two components of VeraSeal to be administered at the same time, and ensures that they mix evenly, which is important for the sealant to work at its best.
The amount of VeraSeal that will be applied depends on a number of factors, including the type of surgery, the size of the area to be treated during your operation and the way VeraSeal is applied. The surgeon will decide how much is appropriate, and will apply just enough to form a thin, even layer. If it does not seem to be enough, a second layer can be applied.
4. Possible side effects
Like all medicines, this medicine can cause side effects, although not everybody gets them. VeraSeal contains the component of fibrin sealant. Fibrin sealants may, in rare cases (up to 1 in
1,000 people), cause an allergic reaction. If you experience an allergic reaction you might have one or more of the following symptoms: swelling under skin (angioedema), skin rash, hives or wheals (nettle-rash), tightness of the chest, chills, flushing, headache, low blood pressure, lethargy, nausea, restlessness, heart rate increase, tingling, vomiting or wheezing. In isolated cases, these reactions may progress to a severe allergic reaction. Allergic reactions may especially be seen if the preparation is applied repeatedly, or administered to patients known to be allergic to constituents of the product. If you experience any of these symptoms after surgery, you should immediately consult your doctor or surgeon.
There is also a theoretical possibility that your immune system will produce proteins to attack VeraSeal and, that these may interfere with your blood clotting. The frequency of this type of event is not known.
If this product is accidentally placed inside a blood vessel, it can lead to blood clots, including disseminated intravascular coagulation (DIC) (when blood clots form throughout the blood vessels in the body). There is also a risk of a severe allergic reaction.
Side effects which were reported during clinical trials with VeraSeal included:

Other sources of information
Detailed information on this medicine is available on the European Medicines Agency web site:
http://www.ema.europa.eu
---------------------------------------------------------------------------------------------------------------------------
The following information is intended for healthcare professionals only:
Posology and method of administration
The use of VeraSeal is restricted to experienced surgeons who have been trained in the use of this medicinal product.
The volume of VeraSeal to be applied and the frequency of application should always be oriented towards the underlying clinical needs for the patient.
31
The dose to be applied is governed by variables including, but not limited to, the type of surgical intervention, the size of the area and the mode of intended application, and the number of applications.
Application of the product must be individualised by the treating physician. In clinical trials, the individual dosages have typically ranged from 0.3 to 12 ml. For other procedures, larger volumes may be required.
The initial volume of the product to be applied at a chosen anatomic site or target surface area should be sufficient to entirely cover the intended application area. VeraSeal should be applied as a thin layer. The application can be repeated, if necessary.
Incompatibilities
This medicinal product must not be mixed with other medicinal products.
Special precautions
For epilesional use only. Do not apply intravascularly.
Life threatening thromboembolic complications may occur if the preparation is unintentionally applied intravascularly.
When using accessory tips, the instructions for use of the tips should be followed.
Before administration of VeraSeal, care must be taken that the parts of the body outside the desired application area are sufficiently protected (covered) to prevent tissue adhesion at undesired sites.
VeraSeal should be applied as a thin layer. Excessive clot thickness may negatively interfere with the product’s efficacy and the wound healing process.
Instructions for use
Read this leaflet before you open the package.
Handling of VeraSeal
VeraSeal comes ready to use in sterile packages and must be handled using sterile technique in aseptic conditions. Discard damaged packages as re-sterilisation is not possible.
• Thawing
Room temperature thawing
VeraSeal should be thawed at room temperature (20 ºC - 25 ºC) for approximately eighty (80) minutes for the 2 ml and the 4 ml presentations and one hundred twenty (120) minutes for the
6 ml and the 10 ml presentations. The steps required for thawing are:
- Open the cardboard case and take out the inner contents.
- Place this packaging on a surface at room temperature.
After thawing, it is not necessary to warm the product for its use.
Water bath
In case thawing times need to be shortened, a thermostatic water-bath could be used, but always at a temperature not higher than 37 ºC. At 37 ºC the times needed are approximately
twenty (20) minutes for the 2 ml and the 4 ml presentations and thirty (30) minutes for the 6 ml and the 10 ml presentations. The steps required for thawing are:
32
- Open the cardboard case and take out the inner contents.
- Place this packaging into water bath.
- Ensure this packaging remains submerged throughout thawing.
The temperature must not exceed 37 ºC.
• Preparation
After thawing the solutions must be clear to slightly opalescent and colourless to pale yellow. Solutions that are cloudy or have deposits should not be used.
Transferring operations include:
- Remove the packaging from the surface at room temperature, from the refrigerator at 2 °C - 8 °C or from the water bath (and dry the outer pouch) after thawing.
- Open the outer pouch and remove the sterile inner blister.
- Open the inner blister and make the VeraSeal syringe holder available to a second person for transfer to the sterile field. The outside of the blister package should not come in contact with the sterile field.
Connection operations include:
- Hold the VeraSeal syringe holder slightly inclined upwards.
- Unscrew and remove the tip cap of both fibrinogen and thrombin syringes.
- To remove air bubbles from syringes, strike gently the side of the syringes one or two times while keeping the syringe holder in an upright position and eject air.
- To attach the applicator tip, screw both syringes consecutively, making a quarter (90 degree) turn each time.
Please see pictogram at the end of this leaflet.
• Application by dripping
VeraSeal must be applied with the syringe holder supplied.
VeraSeal must be applied with the cannula provided with the product, or an equivalent CE-marked cannula (including open surgery and laparoscopic use devices) intended for that use. When using the provided cannula, follow the connection instructions described above. When using other applicator tips, the instructions for use of the tips should be followed.
When dripped, the tip of the applicator should be kept as close as possible to the tissue surface, but without touching the tissue during application. Individual drops should be applied to the area to be treated.
To prevent uncontrolled clotting, the drops should be allowed to separate from each other and from the tip of the applicator.
• Application by spraying
VeraSeal must be applied with the syringe holder provided. VeraSeal should only be applied if it is possible to accurately judge the spray distance (see also section 2).
VeraSeal must be applied with the spray device that is supplied separately, or an equivalent CE-marked spray device (including open surgery and laparoscopic use devices) intended for that use. Always refer to the specific instructions provided with the device packages.
33
To avoid the risk of potentially life-threatening air or gas embolism VeraSeal is recommended to be sprayed using pressurised CO2 (see table below).
Connect the short gas tube on the application device to the luer-lock end of the filter tubing. Then connect the luer-lock of the gas tube to a pressure regulator capable of delivering
15 - 25 psi (1.0 - 1.7 bar) of gas pressure. The pressure regulator should be used in accordance with the manufacturer’s instructions.
When applying VeraSeal using a spray device, it must be ensured that the pressure and the distance from the tissue are within the ranges recommended by the marketing authorisation holder of VeraSeal, as given in the following table:
