Active clinical trials for "Pain, Postoperative"

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.

The purpose of this study is to compare different skin closure materials for the transobturator suburethral sling procedure. Currently the investigators are using monocryl suture material as the standard for skin closure. This material has anecdotally show to be very irritating to patients who have had this type of surgery. Our study will compare the monocryl suture material with vicryl (polyglactin 910) and dermabond (2-octyl cyanoacrylate) skin glue. The investigators believe that vicryl suture material will be superior in comfort when compared to monocryl and dermabond for this type of procedure.

Using Magnetic resonance (MR) scanning and ultrasonography the investigators wish to investigate, in what way a known volume of local anesthetic injectate will be distributed in the transverse abdominis plane (TAP) in young healthy male volunteers. The investigators compare the anatomical distribution of the local anesthetic injectate in the TAP when performing an ultrasound-guided classical TAP block and a Dual TAP block. The investigators also want to compare the spread of anesthetized frontal dermatomes when performing an ultrasound-guided classical TAP block and a Dual TAP block.

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 whether continuous intravenous ketorolac infusion reduces pain in patients who are having laparoscopic surgery to donate a kidney.

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 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.

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
