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.

Condition Intervention Phase
Blood Loss
Device: Bipolar Sealer (Aquamantys)
Procedure: Standard of Care
Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Health Services Research
Official Title: A Post-Market, Prospective, Multicenter, Randomized Trial Comparing the Use of Standard of Care Blood Sparing Techniques With and Without the Aquamantys System to Facilitate Hemostasis in Subjects Undergoing Multi-level Spinal Fusions

Further study details as provided by Salient Surgical Technologies:

Primary Outcome Measures:
  • Actual Peri-operative Blood Loss [ Time Frame: Up 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:
  • Frequency and volume of transfusions [ Time Frame: Up to 72 hours post-operatively ]
    The frequency and volume of transfusions will be measured between treatment groups

  • Reduction in hemoglobin and hematocrit values post-operatively [ Time Frame: Upto 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 time [ Time Frame: Up to 21 days post-operatively ]
    Total length of staycosts and operative time will be compared between treatment groups.

Enrollment: 12
Study Start Date: April 2011
Estimated Study Completion Date: April 2013
Estimated Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Bipolar Sealer
Standard of care blood sparing techniques with bipolar sealer
Device: Bipolar Sealer (Aquamantys)
Standard of care blood sparing techniques along with the use of bipolar sealer
Other Name: Aquamantys
Active Comparator: Control
Standard of care blood sparing techniques without the use of bipolar sealer
Procedure: Standard of Care
Standard of care blood sparing techniques without the useof bipolar sealer

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

Ages Eligible for Study:   18 Years to 70 Years   (Adult, Senior)

  3. Planned use of hypotensive anaesthesia
  4. Pregnant or lactating
  5. Morbid obesity, defined as Body Mass Index (BMI) greater than 40
  6. Previously diagnosed coagulopathy or bleeding diasthesis

  13. Platelet count <100K in the 14 days prior to surgery
  14. Based on clinical history, physical exam and subject presentation, subject has or is suspected to have a history of alcohol and/or drug abuse that would preclude subject from providing adequate consent and/or complying with study requirements
  15. Prisoner or transient
  16. Enrolled in another drug or device investigational study (currently or within past 30 days)
  17. Unable or unwilling to sign the Informed Consent Form or comply with protocol specified procedures
