Active clinical trials for "Postoperative Nausea and Vomiting"

The purpose of this research study is to evaluate the drug gabapentin (Neurontin®) for its ability to reduce postoperative pain, the need for morphine-like pain medication, and the severity and frequency of postoperative nausea and vomiting in laparoscopic gastric bypass surgery patients.

The investigators want to test the efficacy of these anesthetic antiemetic measures collectively with or without ondansetron or dexamethasone, in the prevention of postoperative nausea and vomiting (PONV) in patients undergoing laparoscopic cholecystectomy.

The objective of the study is to examine the effect of the addition of intravenous dexamethasone 1.5 hours prior to induction of anesthesia on the post-operative opioid consumption, pain scores, fatigue, and recovery in patients undergoing gynecological surgery with laparotomy under general anesthesia. This is a dose finding study with two different doses (0.1 mg/kg vs. 0.2 mg/kg) of dexamethasone to find out the optimal efficacious dose of dexamethasone with minimal side effects. Dexamethasone has anti-inflammatory, immunomodulatory, and analgesic effects; and is superior to placebo in providing post-operative pain control, lower analgesic consumption, prevention of postoperative nausea and vomiting, lesser post-operative fatigue, and better recovery profile. No dose response study has been done. The investigators hypothesize that a higher dose of dexamethasone may have an incremental beneficial effect.

Keyhole surgery for bowel disease has brought great benefits, enabling patients to recover quicker from surgery and so return to normal activities. Although keyhole surgery reduces pain following abdominal surgery, it still causes enough pain to require strong pain killing medications such as morphine-like drugs which, although good pain killers, can have a detrimental effect on the recovery of bowel function, leading to feelings of nausea and vomiting and ultimately delaying recovery. These side-effects can reduce the potential benefits from keyhole surgery and our "fast-track" recovery programmes. The aim of this project is to assess the effectiveness of a new method of pain control after keyhole bowel surgery. The study involves the injection of local anaesthetic into the abdominal muscles once the patient is anaesthetised. Although use of local anaesthetic is common practice, we are looking at a new technique of injecting it called a transversus abdominis plane (or TAP) block. This technique will attempt to block the pain nerves to the abdomen prior to the operation beginning. We plan to investigate whether this new technique will reduce the amount of pain following keyhole bowel surgery. If successful, it might be used to further enhance people's recovery from bowel surgery.

The purpose of the Study is to test a higher dose of steroids(Dexamethasone) given just prior to surgery in the setting of Fast-Track Hip-surgery with Arthroplasty in a group of expected High Pain Responders and the effect on postoperative pain and postoperative inflammation.

Recommendation is strong on physical activity (PA) in the prehabilitation of Enhanced Recovery After Surgery (ERAS) for various types of surgeries. The evidence is however weak regarding ERAS protocols. Many studies have showed that physical exercise and PA have hypoalgesic effects on healthy individuals and they have better pain tolerance too. Here the investigators study changes in postoperative pain and postoperative nausea and vomiting for various types of surgical patients after performing preoperative PA at moderate or vigorous intensity Vs non-preoperative PA patients.

To compare the anti-nausea and vomiting effect between glycopyrronium in combination with tropisetron and normal saline in combination with tropisetron for patients receiving elective surgery under general anesthesia. Based on this study the investigators intend to explore the feasibility of using glycopyrronium as adjuvant drug to prevent postoperative nausea and vomiting.

The purpose of this study is to determine if intravenous fosaprepitant can interfere with nervous system monitoring signals in patients having surgery under general anesthesia. This medication has numerous effects on the sensory nerve transmission which can theoretically have effects on the ability to accurately measure somatosensory evoked potentials.

The investigators tested the hypothesis that administration of intravenous dextrose as a maintenance fluid in gynecologic laparoscopic surgery would reduce the incidence and severity of postoperative nausea and vomiting (PONV) compared with normal saline solution in the same dose. A prospective randomized double blinded controlled study was conducted. Eighty six participants were randomized to dextrose solution (n= 42) or normal saline solution (n= 44). The Bellville postoperative nausea and vomiting scores were recorded until 24 hours after surgery.
