1) 18 years of age or older.
2) Undergoing a planned elective iliac crest bone graft, pelvic osteotomy or spinal fusion. Spinal surgery can be the entire spine although the spinal fusion should be confined to one or two-levels e.g. one or two level cervical, thoracic or lumbar.
3) Likely to have an intraoperative surgical site involving cancellous bone that the surgeon would typically treat with another topical haemostatic agent to control the bleeding.
4) Willing to provide informed consent and to comply with the requirements of the study protocol, including the six weeks follow-up evaluation.
5) Pre-operative platelet count > 150,000, INR < 1.3 and aPTT < 44.0 sec.
6) Pre-operative Haemoglobin > 12 gm/dL in females or > 13 gm/dL in males.
1) Surgery at the intended application site <= 6 months before the current surgical procedure.
2) Active infection at the surgical site.
3) Pregnancy, as determined by urine pregnancy test, or breast feeding.
4) Abnormal liver function.
5) Use of anticoagulant therapy (e.g., Coumadin, heparin, clopidogrel), non-steroidal anti-inflammatory medications or fish oil supplements within 7 days of the surgery except for aspirin (maximum dose 150 mg per day).
6) Blood dyscrasia.
7) Presence of a spinal tumour, intradural pathology, or prior spinal fusion surgery at the same target site.
8) Participation in another clinical study with an investigational product within the past 30 days.
9) Known allergy to human fibrinogen or human thrombin.
10) Compromised immune system.
11) Contraindicated use of a haemostatic agent.
12) Fibrinolytic disorders requiring intraoperative antifibrinolytic treatment.
13) Haematological disease (thromboembolic events, haemoglobinopathy, coagulopathy or haemolytic disease).
14) Significant co-morbidities: previous MI; severe ischemic heart disease (NYHA Class III, IV); severe pulmonary disease; chronic renal failure; hepatic failure; uncontrolled hypertension.
15) Unwilling to receive blood products.
Study & Design
- Study Type
- Interventional
- Study Design
- Not specified
- Primary Outcome Measures
Name Time Method Proportion of subjects that achieve controlled haemostasis at target bleeding site at 3 minutes. â??Controlled haemostasisâ?? is when bleeding from the exposed bone surfaces is either insignificant and does not require further treatment with any haemostatic action or stopped completely.Timepoint: 3 Minutes
- Secondary Outcome Measures
Name Time Method 1. Assess the need for repeat application of the dressing and determine if the repeat application results in controlled bleeding. <br/ ><br>2. Negative immunogenicity response as determined by assay of coagulation factors (PT, aPTT, INR and fibrinogen levels). <br/ ><br>3. Assess dressing characteristics including: dissolvability, ease of preparation, conformability and ease of use via a handling questionnaire. <br/ ><br>4. Collect information on blood loss through the standard of care of the hospital.Timepoint: 6 Weeks
