Salient Aquamantys Spine Trial

Phase 4
Terminated
Conditions
Blood Loss
Interventions
Device: Bipolar Sealer (Aquamantys)
Procedure: Standard of Care
Registration Number
NCT01331499
Lead Sponsor
Salient Surgical Technologies
Brief Summary

The purpose of this study is to compare standard of care hemostasis techniques with and without the use of Aquamantys in reducing peri-operative blood loss.

Detailed Description

The primary objective of the study is to assess the effectiveness of Aquamantys in reducing peri-operative blood loss compared with standard electrocautery

Secondary objectives include :

* Rate and volume of transfusions

* Evaluating the reduction in hemoglobin and hematocrit values post- operatively

* LOS costs, and operative time

* Gathering operator feedback on qualitative criteria, including ease of use and surgical visualization between the two treatment groups

Primary Outcome Measures
NameTimeMethod
Actual Peri-operative Blood LossUp to 72 hours post-operatively

Actual blood loss (ABL) will be calculated using a study specified formula using laboratory data from up to 72 hours post-surgery. ABL will be compared between treatment groups

Secondary Outcome Measures
NameTimeMethod
Frequency and volume of transfusionsUp to 72 hours post-operatively

The frequency and volume of transfusions will be measured between treatment groups

Reduction in hemoglobin and hematocrit values post-operativelyUpto 72 hours post-operatively

The reduction in hemoglobin and hematocrit values will be evaluated between the two treatment groups

Length of stay costs and operativ timeUp to 21 days post-operatively

Total length of staycosts and operative time will be compared between treatment groups.
