Active clinical trials for "Pain, Postoperative"

Aim of this study is to compare benefits and disadvantages in using continuous infusion of morphine or fentanyl for post operative analgesia.

This study is designed to evaluate lung function and pain control of continuous supraclavicular versus suprascapular versus interscalene nerve catheters in subjects undergoing total shoulder replacement. The investigators hypothesize that all three groups would have similar pain control; the supraclavicular and suprascapular groups may have better lung function.

This is a single center placebo controlled, prospective, randomized study on healthy adults undergoing third molar surgery.

The purpose of our study is to evaluate whether utilizing ultrasound assessment during caudal epidural injection can reliably identify unrecognized and unsuccessful nerve blocks during the procedure, guide proper technique, and alter pain management outcome measurements for patients. Patients will be randomized to a group either undergoing caudal injection by a trainee using typical techniques or by using typical techniques in addition to ultrasound for confirmation of successful injection. The patients enrolled in this study will have the same intraoperative care, in line with the standard of care. Data will be collected intraoperatively and postoperatively on pain scores, time for performance of caudal block, and perceived success of the block. There will be no direct benefit to the patients enrolled in this study, but future patients may benefit from the use of ultrasound for the confirmation of a successful block.

This is a pilot study investigating the use of abdominal binders after cesarean sections. The researchers are testing whether elastic abdominal binders improve postoperative pain control and reduce postoperative blood loss. Blood loss and pain control are both concerns after giving birth. It is hoped that the use of an abdominal binder after giving birth will provide a non-pharmacologic way to to reduce blood loss and manage pain.

This study was designed to assess whether the injection of local anesthetic into the nerve (intraneural), as opposed to around it (perineural), leads to longer anesthesia and analgesia of the leg. Some reports of accidental intraneural injection mention an extremely long duration. When different drugs and doses were evaluated in a clinical trial of intraneural injection, a longer-than-expected duration was reported. The investigators will compare the two types of injection using the same drug, so as to determine if there is an actual difference in duration.

This is a single-blind randomized clinical trial. Patients undergoing abdominal tumor surgery were recruited to participate in the study. Apart from routine treatment in the surgical intensive care unit, the subjects were randomly divided into two groups: Propofol group (Group P) and Dexmedetomidine group (Group D) and received continuous intravenous infusion of Propofol (infusion dosage range: 0.3 ~ 1.6 mg/kg/h) or Dexmedetomidine (infusion dosage range: 0.1 ~ 0.7 mcg/kg/h) according to their assigned group. Patients' hemodynamic status was monitored using a chest Bioreactance technique, Continuous Non-Invasive Cardiac Output and Hemodynamic Monitor at preset time points (time of recruitment [0h], 2, 4, 6, 12h and 24h). Clinical data such as vital signs, hemodynamic parameters, laboratory results, fluid volume and drugs used were also recorded.

The purpose of this study is to examine pain associated with thoracotomy (incision made during surgery to obtain access to your thoracic cavity) and how the closure technique may influence postoperative pain. Two types of routinely selected thoracotomy closure techniques will be examined; pericostal and intracostal sutures. The investigators hypothesize that intracostal sutures will result in less postoperative and chronic pain as a result of less compression of the intercostal nerve.

The investigators hypothesize that the administration of physostigmine in the postoperative period after nephrectomy reduces opioid consumption.

The aim of this investigation is to assess the impact of forced air warming, warm humidified insufflation gas and the combination of the two on intraoperative temperature maintenance and the postoperative pain course as well as the fibrinolytic activity in peritoneal fluid following laparoscopic procedures (duration > 60 min) in a prospective, randomized, controlled, mono-centric study. Therefore 150 subjects will be randomized in 3 groups of 50 subjects each. First group will be treated with forced-air warming blanket (bair hugger). Second group will be treated with warmed, humidified insufflation via the F&P HumiGard™ Surgical Humidification System. Third group will be treated with both, warming blankets and warmed, humidified insufflation. The peri-operative temperature of patients might be higher in patients of the third group with the combination of both treatments. The investigators hypothesize that VAS scores for pain (especially shoulder pain), and MEDD usage will differ between groups. Wound infection incidence and time spent in PACU are also expected to differ. Fibrinolytic activity in the peritoneal fluid is expected to be higher in patients undergoing laparoscopic procedures with humidified gas insufflation, since the trauma to the peritoneum will be less.
