  Purpose

Remote Ischemic PreConditioning (RIPC) will improve the postoperative pain experience in patients undergoing abdominal surgery. Although abdominal surgery can be a lifesaving procedure many people have a significant amount of postsurgical pain. Severe postsurgical pain may lead to chronic pain in some people. "Remote Ischemic Preconditioning" may reduce the amount of postsurgical pain. Remote ischemic preconditioning is done by inflating a balloon (very similar to a blood pressure cuff) on the leg until it blocks blood flow for a few minutes. The cuff is then deflated and blood flow resumes. The process is repeated up to three times. This procedure causes the body to increase its natural pain relief system that may help to decrease the amount of postsurgical pain.


Condition Intervention
Pain
 Device: Thigh Tourniquet (VBM Single Use Tourniquet Cuff Items 20-34-722SLZ-1)
Device: Sham RIPC

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator)
Primary Purpose: Treatment
Official Title: Remote Ischemic Preconditioning (RIPC) and Its Effect on the Postoperative Pain Experience Following Intra-abdominal Surgery

Further study details as provided by Wake Forest University Baptist Medical Center:

Primary Outcome Measures:
  • Comparison of pain intensity and unpleasantness postoperatively [ Time Frame: Postoperative day 1 and postoperative day 2 ] [ Designated as safety issue: No ]
    Pain intensity and upleasantness will be measured on postoperative day 1 and 2 by using a 0-10 verbal scale after asking the subject to cough.


Secondary Outcome Measures:
  • Opioid consumption [ Time Frame: Postoperative day 1 and postoperative day 2 ] [ Designated as safety issue: No ]
    All opioids administered during postoperative day 1 and 2 will be recorded.

  • Consumption of nonopioid analgesics [ Time Frame: Postoperative day 1 and postoperative day 2 ] [ Designated as safety issue: No ]
    All non-opioids analgesics administered during postoperative day 1 and 2 will be recorded.
