Active clinical trials for "Pain, Postoperative"

The purpose if to find out if analgesia with bilateral ultrasound-guided Tranversus Abdominis Plane (TAP) block with Ropivacaine 0.5% is better than analgesia with local infiltration of trochar sites with Ropivacaine 0.5% in patients undergoing laparoscopic cholecystectomy. Our hypothesis is that in laparoscopic cholecystectomy, bilateral TAP blocks will reduce postoperative pain scores when compared to conventional postoperative pain control with local infiltration of trochar insertion sites.

The aim of this research project is to compare electrocautery to scalpel for laparotomy skin incisions, with the following objectives: To investigate whether electrocautery produces a cosmetically inferior surgical scar. To compare the rates of wound infection with each technique. To determine if electrocautery results in less postoperative pain. Our null hypothesis is that electrocautery is equivalent to scalpel for creating skin incisions; with respect to wound cosmesis, wound infection rate, and post-operative pain.

Pain after tonsillectomy can be severe and last ten days. Various new surgical instruments have been developed over the years in an attempt to reduce postoperative pain with mixed results and increased costs; no single tonsillectomy technique is superior to the rest. Patients are discharged to home usually on the day of surgery and often suffer significant pain and nausea. Pain medication is often prescribed which can cause nausea, vomiting and constipation. Children in pain are reluctant to take in fluids and may require intravenous hydration at an emergency department. "Battlefield acupuncture " has been recently developed by the US Air Force and is now being used in Iraq and Afghanistan on wounded warriors suffering severe acute pain from trauma. This protocol consists of five acupuncture points on the outer ear. A recent study has demonstrated decreased pain and agitation in children undergoing ear tube insertion. Ear tube patients have mild discomfort compared to tonsillectomy patients and are able to attend school the next day. The investigators have been encouraged by the benefits of acupuncture during surgery for ear tube patients and also wounded warriors recovering from their injuries. These findings motivated us to see if acupuncture during tonsillectomy surgery would result in less pain and nausea.

To investigate if the use of perioperative neuraxial blockade reduces post-operative mortality and cardiorespiratory events compared to intraoperative general anesthesia AND postoperative IV narcotic analgesia. This is a feasibility study to determine if recruitment and execution of the protocol could be done in a timely manner in a much larger trial

Pregabalin 300mg or placebo are administered 1 hour preoperatively in patients undergoing elective nephrectomy. Postoperatively, patients receive a patient controlled analgesia device for self delivering opioids. Morphine consumption in the first 48 hours is documented. Hyperalgesia is measured by von-Frey-Filaments.

In a randomized, double-blind, cross-over trial, 48 patients scheduled for total knee arthroplasty with placement of an intracapsular catheter will be randomized to receive bolus injection of ropivacaine in high volume/low concentration (20 ml, 5 mg/mL) or low volume/high concentration (10 mL, 10 mg/mL) 6 and 24 hours postoperatively, and pain will be assessed at rest and with mobilization for 2 hours after injections.

The purpose of this study is to determine whether continuous intravenous ketorolac infusion reduces pain in patients who are having laparoscopic surgery to donate a kidney.

This research study is to determine the relative times for perineural catheter placement with the use of ultrasound versus electrical stimulation. The perineural catheter is placed next to the nerves through which local anesthetic is placed to provide pain control following surgery. This study may determine if one method is associated with increased success rate and patient comfort.

We hypothesize that pregabalin will decrease post-operative pain scores and opioid use following abdominal hysterectomy compared to placebo. This study has been designed to determine if after an abdominal hysterectomy, the addition of pregabalin to their peri-operative analgesia regimen will demonstrate superior analgesia compared to placebo in terms of lower pain scores and reduced usage of opioids. The primary outcome will be post-operative pain, measured by total opioid consumption. Do women undergoing an abdominal hysterectomy with general anesthesia and receiving pregabalin prior to their surgery and 12 hours later have lower opioid consumption in the first 24 hours after their surgery than those women who received placebo?

The purpose of this study is to determine if pre-incisional lidocaine injection, instilled liquid bupivacaine, intra-abdominal aerosolized bupivacaine, or post-operative bupivacaine injection is superior in post-operative pain control in laparoscopic bariatric surgical patients.
