Brief Summary:
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 or disease Intervention/treatment
Pain Device: Thigh Tourniquet (VBM Single Use Tourniquet Cuff Items 20-34-722SLZ-1) Device: Sham RIPC

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 64 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Care Provider, Investigator)
Primary Purpose: Treatment
Official Title: Remote Ischemic Preconditioning (RIPC) and Its Effect on the Postoperative Pain Experience Following Intra-abdominal Surgery
Study Start Date : June 2011
Primary Completion Date : April 30, 2016
Study Completion Date : April 30, 2017

Arm Intervention/treatment
Active Comparator: RIPC
A tourniquet on the thigh will be inflated to 300 mmHg for 5 minutes then deflated for 5 minutes. This will be repeated three times
Device: Thigh Tourniquet (VBM Single Use Tourniquet Cuff Items 20-34-722SLZ-1)
Disposable sterile thigh tourniquet
Other Name: VBM Single Use Tourniquet Cuff Items 20-34-722SLZ-1
Sham Comparator: Sham RIPC
A tourniquet on the thigh will be inflated to 15 mmHg for 5 minutes then deflated for 5 minutes. This will be repeated three times
Device: Sham RIPC
Disposable sterile thigh tourniquet
Other Name: VBM Single Use Tourniquet Cuff Items 20-34-722SLZ-1



Primary Outcome Measures :
  1. Comparison of Pain Intensity and Unpleasantness Postoperatively [ Time Frame: Postoperative day 1 and postoperative day 2 ]
    Pain intensity and unpleasantness will be measured on postoperative day (POD) 1 and 2 by using a 0-10 verbal scale after asking the subject to cough. Higher scores denotes more intensity and unpleasantness of pain.


Secondary Outcome Measures :
  1. Opioid Consumption [ Time Frame: Postoperative day 1 and postoperative day 2 ]
    All opioids administered during postoperative day 1 and 2 will be recorded.

  2. Consumption of Nonopioid Analgesics [ Time Frame: Postoperative day 1 and postoperative day 2 ]
    All non-opioids analgesics administered during postoperative day 1 and 2 will be recorded.
