Filter by:Pain management is becoming an important ethical responsibility of the medical profession and a focus of the health care system. However, there are limited literature evaluate the postoperative pain experience and management in our local setting.
Aim of this study is to compare benefits and disadvantages in using continuous infusion of morphine or fentanyl for post operative analgesia.
Fentanyl is a potent opioid, it is theoretically 100 times more potent that morphine and in severe acute postoperative pain acts faster than its congener (morphine ) for pain relief . In the literature there is no study that corroborates this theoretical assumption and proposes to compare which has fewer adverse effects. This drug produces effects similar to those reported for morphine but less magnitude and has the advantage that during the postoperative period respiratory depression, antitussive effect , gastrointestinal discomfort and physical dependence are manifested in a significantly less degree. Trying to solve the management of postoperative pain relief , our objective is to determine by controlled clinical trial of superiority if in adult patients undergoing surgery , fentanyl reduces faster qualification time of severe pain to mild pain in the postanesthesia care unit compared to morphine.
The investigators are attempting to see if eliminating the amount of long acting spinal narcotic during cesarean section delivery will demonstrate pain scores with movement when evaluated 24 hours postoperatively as those that receive the standard dosage of spinal narcotic when combined with oral acetaminophen or placebo. The investigators also are evaluating if there are decreased side effects related to decreased narcotic usage.
Fluctuations of female sex hormones during the menstrual cycle influence pain perception. Endogenous pain is pronounced in the follicular phase of the menstrual cycle. The investigators tested the primary hypothesis that the women having surgery during their follicular phase have more acute pain and require more opioids than those in the luteal phase, and secondarily the investigators tested that women who have surgery during their follicular phase have more incisional pain at 3 month postoperatively.
Viedo-assisted thoracoscopic surgery(VATS) have became popular in recent years. There is no golden rule of postoperative analgesia for VATS. Compared with lobectomy, wedge resection preserves better pulmonary function and is suitable for elder patients and patients who could not afford to have lobectomy. In addition to surgery time、recovery time and hospital stay, wound incisions and organization damages are different,too. Will patients also have different response to pain control after these two surgery? The retrospective study is to compared the differences of postoperative pain management between VATS lobectomy and wedge resection.
The purpose of this study is to learn how well Liposomal Bupivacaine (Exparel™) controls post-operative pain in patients undergoing both open and laparoscopic (minimally invasive) abdominal hernia repair surgery.
The purpose of the study is to determine the minimum effective concentration of bupivacaine (EC50) in femoral block for analgesia by ultrasound after knee surgery.
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.
Total knee prosthetic replacement causes severe postoperative pain. Various analgesic techniques have been used in pain control. Comparison of epidural and femoral nerve block is lacking, furthermore effect on chronic pain is unclear. The investigators aimed to compare the effects of epidural and femoral block on acute and chronic postoperative pain.
