This is a single blind, randomized, prospective study comparing SURGICEL Powder with SURGICEL Original (control arm) as an adjunct to achieve hemostasis in the control of capillary, venous, and small arterial hemorrhage when ligation or other conventional methods of control are impractical or ineffective during surgery (open, laparoscopic, or thoracoscopic) in Chinese adult subjects.

This is a single blind, randomized, prospective study comparing SURGICEL Powder with SURGICEL Original (control arm) as an adjunct to achieve hemostasis in the control of capillary, venous, and small arterial hemorrhage when ligation or other conventional methods of control are impractical or ineffective during surgery (open, laparoscopic, or thoracoscopic) in Chinese adult subjects.

After application of either SURGICEL Powder or SURGICEL Original, the target bleeding site (TBS) will be assessed for hemostasis (no detectable bleeding) at 3, 5, and 10 minutes from application and prior to initiation of final fascial closure on open surgery or port site closure in laparoscopic or thoracoscopic procedures.

All enrolled subjects will be observed post-operatively through discharge and followed up at 30 days (+14 days) and at 6 months (+/-30 days) post-surgery via phone call or office visit.

Inclusion Criteria:

1. Adult subjects aged ≥18 years requiring elective/non-emergent open or laparoscopic general, gynecological, or cardiothoracic surgical procedures.
2. Subject or authorized representative has signed the approved Informed Consent.
3. Subject(s) whose platelet count is ≥100,000 per microliter and International Normalized Ratio (INR) is <1.5 prior to 24 hours of surgery.
4. Presence of an appropriate TBS identified intra-operatively by the surgeon.
5. Subject(s) undergoing cardiothoracic surgery with anticoagulation must have anticoagulation reversed prior to TBS identification and treatment.

Exclusion Criteria:

1. Female subjects who are pregnant or nursing.
2. Subject on heparin within 12 hours prior to surgery, or oral Coumadin (warfarin) and/or Factor Xa inhibitors within 3 days prior to surgery.
3. Subject on antiplatelet/P2Y12 inhibitors medication 5 days prior to surgery;
4. Subject is currently participating or plans to participate in any other investigational product or drug trial without prior approval from the Sponsor.
5. Subjects who are known, current alcohol and/or drug abusers.
6. Subjects with any pre-operative findings identified by the surgeon that may preclude conduct of the study procedure.
7. Subjects with any intra-operative findings identified by the surgeon that may preclude the use of study product.
8. Subject with TBS in an actively infected field (Class III Contaminated or Class IV Dirty or Infected; see Appendix 1).
9. TBS is on arteries or veins where application of SURGICEL Powder would present a risk of introducing the study product into an open blood vessel.
10. Major arterial or venous bleeding or major defects in arteries and veins.
11. TBS where silver nitrate or any other escharotic chemicals have been applied.
12. TBS is in, around, or in proximity to foramina in bone, or areas of bony

All adverse events (serious and non-serious), whether attributable to device/procedure or not, were recorded from enrollment (informed consent and subject met all incl/excl criteria), during surgical procedure, and until completion of 30-day follow-up visit. Between 30 day and 6 month visit, all SAEs requiring surgical intervention and assessed as possibly/related to study treatment were recorded. All deaths were recorded regardless of relationship to product or procedure.

For this study, an adverse event was any untoward medical occurrence (sign, symptom or disease) in a subject and which does not necessarily have a causal relationship with the study medical device. An untoward medical occurrence includes any new, undesirable medical experience or worsening of a pre-existing condition.
