Active clinical trials for "Postoperative Nausea and Vomiting"

The aim of this study is to evaluate the effect of the aromatherapy with lavender, rose or ginger essential oils on nausea, vomiting and postoperative quality of recovery scores in patients with postoperative nausea and vomiting.

We would like to know the prophylactic anti-emetic effect of ramosetron compare to ondansetron in patient undergone total knee arthroplasty with spinal anesthesia and intrathecal morphine .

Currently nearly 70% or more surgeries are being done as ambulatory (day care) procedures as they offer significant benefit to the patients as well as to the hospitals. Inadequate pain relief (30%-40%) and nausea-vomiting form the leading factors affecting the quality of care and hence its efficiency. Opioids form the primary modality to treat moderate to severe pain, but can also cause significant nausea-vomiting and other side effects. Although hydromorphone is five times more potent than morphine, in equianalgesic doses they both could provide similar pain relief. They both exert no ceiling effect for their analgesia, and hence incomplete or inadequate analgesia is related to the appearance of side effects. In this study the investigators shall assess the proportion of patients who satisfy the outcome of 'satisfactory analgesia with minimal nausea-vomiting' in ambulatory surgeries, assessed at 2 hours after surgery. Patients would be randomized to receive either morphine or hydromorphone in the surgical recovery area. All personnel involved with the study would be blinded. The investigators will also look to assess the time to discharge and other side effects. This will help to choose the better drug, thereby improving pain relief and side effects, and also the efficiency of health care delivery.

Addition of nitrous oxide N2O towards the end of prolonged isoflurane anesthesia hastens patients recovery. The hypothesis is that the addition of N2O at the end of prolonged sevoflurane anaesthesia also hastens early recovery without increasing the frequencies and intensity of PONV and improves quality of recovery.

There are ca 1000 new cases of bladder cancer in Finland/year. The curative therapy for high risk bladder cancer is radical cystectomy. The golden standard is still an open surgery despite development of laparoscopic techniques. Epidural analgesia is considered as most effective for the treatment of postoperative pain. However, there is a need for other effective options, because epidural analgesia has some contraindications and risks for serious complications. Recently quadratus lumborum block has gained popularity in the treatment of postoperative pain after various surgeries in the area from hip to mamilla. It is more beneficial than other peripheral blocks, since it covers also the visceral nerves. Contrary to the need of epidural catether a single shot QLB has reported to last up to 48 hours. Inadequately treated acute postoperative pain is considered as one of the main risk factors for persistent postoperative pain. 44 patients aging 18-85 will be recruited based on a power calculation. The primary outcome measure is the acute postoperative need for rescue analgesics. Secondary outcomes are acute pain (NRS scale), nausea, vomiting, mobilisation and longterm outcomes such as quality of life and persistent pain.

Two key requirements for discharge from hospital after major abdominal surgery are adequate oral analgesia and resumption of oral nutrition. Up to 40% of patients suffer delayed discharge after abdominal surgery due to delayed return of gut function, manifesting as nausea, vomiting, constipation and abdominal distension. Opiates and their derivatives are the mainstay of postoperative analgesic regimens after abdominal surgery and are highly effective in achieving adequate pain control. However, opioids cause impaired gut function by reducing normal forward propulsion and increasing gut spasm. Opioid receptor blockers such as Alvimopan counteract these effects and can accelerate postoperative gut recovery but are expensive and cause cardiac complications; alternative painkillers such as non-steroidal anti-inflammatories are less effective than opioids and have been linked with increased risk of anastomotic leaks. Targinact is a combination of prolonged release opioid analgesic (oxycodone hydrochloride) and naloxone hydrochloride (an opioid receptor blocker). The formulation of the product confines the naloxone action to the gut to reduce the unwanted side-effects on gut function. Targinact has been shown in patients with chronic severe pain to provide comparable analgesia to other opioid analgesics whilst reducing the unwanted side-effect of constipation. The Investigators wish to test the hypothesis that Targinact will provide adequate analgesia after colonic resection with reduced postoperative gastrointestinal dysfunction. The surgical procedure chosen to test this hypothesis is laparoscopic segmental colectomy, a consistently reproducible intervention with a postoperative gut dysfunction rate of up to 40% (prospective data from the Edinburgh Colorectal Unit). The main outcome of the study will be return of normal gut function at the time of planned discharge (Day 3).

There some evidence regarding the effect of lidocaine for the prevention of nausea and vomiting in adults.

The primary objectives of this study are to analyse the effect of perioperative systemic infusion of lignocaine on postoperative pain, postoperative nausea and vomiting and perioperative levels of inflammatory mediators in patients undergoing elective open abdominal surgeries. The secondary parameters which will be observed during the study are the time to passage of flatus and stools postoperatively.

In this study, we wish to investigate the effect of ultrasound (US) -guided block of the saphenous nerve (SN) and the posterior branch of the obturator nerve (ONP) on postoperative pain and the use of opioids (morphine-like pain medicine) in the first 24 hours following ambulatory knee arthroscopy. We wish to investigate the analgesic effect of these two blocks compared to placebo (injection of local anesthetic with known pain blocking properties compared with injection of a saline solution), when used as a supplement to conventional oral analgesics. We hypothesize that patients receiving the active treatment may experience less pain during the first 24 hours after their operation than patients receiving the placebo treatment, and possibly require less opioid analgesics, experience less opioid related side effects and have a higher function level in this period than patients receiving the placebo treatment.

In our study the investigators want to evaluate the effects of EFTs (emotional freedom techniques) for reducing incidence of PONV (Postoperative nausea and vomiting). The effects of EFTs have been quiet evident on many aspects if the incidence of PONV is reduced then it will be much valuable adjunct to postoperative management of the patients. Our hypothesis was Emotional freedom techniques are very useful to reduce the incidence of postoperative nausea and vomiting after laparoscopic cholecystectomy.
