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.

Comparison of Pain Intensity and Unpleasantness Postoperatively
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.
Time frame: Postoperative day 1 and postoperative day 2
Number of Participants That Consumed Opioids
All opioids administered during postoperative day (POD) 1 and 2 will be recorded and the number of participants that used opioids will be given.
Time frame: Postoperative day 1 and postoperative day 2
Consumption of Nonopioid Analgesics
All non-opioids analgesics administered during postoperative day 1 and 2 will be recorded and the number of participants that used nonopiods will be given.
Time frame: Postoperative day 1 and postoperative day 2
Use of Antiemetics
Number of participants that used an antiemetic postoperative day 1 and postoperative day 2 was recorded.
Time frame: Postoperative day 1 and postoperative day 2
Level of Sedation
The Ramsey Sedation Scale (RSS) was used to determine the level of sedation. Th RSS defines the conscious state from a level 1: the patient is anxious, agitated or restless, through the continuum of sedation to a level 6: the patient is completely unresponsive. The score range is from 1-6, with higher scores denoting worse outcomes.
Time frame: Postoperative day 1 and postoperative day 2
McGill Pain Sensory
The McGill Pain Questionnaire (MPQ) is a three-part pain assessment tool that measures several dimensions of the patient's pain experience. The scale range is 0-78, with higher scores denoting worse outcomes.
Time frame: Postoperative day 1 and postoperative day 2
Leg Pain at 48 Hours
Number of participants that had leg pain at 48 hours.
Time frame: postoperative day 2
Patient Verbal Assessment as to Whether They Received Active Treatment or Placebo
Participants were questioned to see if they knew what interventional group they belonged to.
Time frame: Postoperative day 1 and postoperative day 2
Pain Unpleasantness
Pain 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.
Time frame: Postoperative day 1 and postoperative day 2
