Active clinical trials for "Postoperative Nausea and Vomiting"

A total intravenous anesthesia (TIVA) is a useful anesthetic technique that reduces the incidence of postoperative nausea and vomiting (PONV). Investigator hypothesized the incidence of PONV can be further reduced when palonosetron is added to TIVA.

This study attempts to learn about the effectiveness of a modification to the Transversus Abdominis Plane (TAP) block that works by anaesthetizing the sensory afferents of the abdominal wall postoperatively using ultrasound guidance. The investigators want to see if regional blocks placed by the surgeon intraoperatively to assure regional anesthetic spread in the appropriate plane could reduce error and improve postoperative recovery.

Postoperative nausea and vomiting (PONV) are common complications after surgery. Patients undergoing orthognathic surgery are reported to have a high rate of PONV, especially those undergoing bimaxillary surgery. Activation of cholinergic system plays an important role in the development of PONV. Penehyclidine is an muscarinic antagonists which selectively block M1 and M3 receptors and is commonly used to decrease oral secretion. The purpose of this retrospective cohort study is to investigate whether use of penehyclidine is associated with a reduced risk of PONV in patients undergoing bimaxillary surgery.

Propofol and sevoflurane have different effects on heart rate variability. It has not yet been reported whether this difference in effect remains at recovery time after anesthesia and the difference is related to postoperative nausea and vomiting has not been studied. The aim of this study is observe whether propofol and sevoflurane have different effects on heart rate variability during recovery and the differences can predict the occurrence of postoperative nausea and vomiting.

Cisplatin is one of the most emetogenic drugs used in clinical practice and it could result in poor compliance with chemotherapy. The 5-HT3 receptor antagonists prevent vomiting in acute phase emesis after chemotherapy in 73 - 92% of cisplatin-treated patients when coadministered with steroids, but they appear to lack efficacy in the delayed phase emesis. Ramosetron, a new 5-HT3 receptor antagonists, has been shown to have equivalent efficacy and tolerability and a longer duration of effect than granisetron in preventing acute vomiting in patients undergoing cisplatin-containing chemotherapy. Acute phase emesis was prevented in 84.8% of patients receiving ramosetron plus dexamethasone, but the CR rate of total phase emesis was less than 60%. Aprepitant is a selective, high-affinity NK1 receptor antagonist. Adding aprepitant to 5-HT3 receptor antagonists and steroid improve CR rate of not only chemotherapy induced acute emesis and but also delayed emesis by 11-14 and 20 percentage points, respectively. But until now, there was no information that which 5-HT3 receptor antagonists is the best partner for aprepitant. Therefore, we initiated a prospective, open-label, phase II study to assess the efficacy and tolerability of a combination of ramosetron, aprepitant and dexamethasone (RAD) in the prevention of cisplatin based CINV in chemotherapy-naïve patients with solid cancer

The combination of aprepitant and lower dose dexamethasone is superior to aprepitant alone with respect to the proportion of patients with a complete response (no vomiting and no use of rescue therapy) during 24 hours after the placement of last suture/staple.

The effect of airway management on vomiting after strabismus surgery is unknown. The purpose of this study is to find out whether the use of different airway devices, such as LMA, which is a special mask placed in the throat or Endotracheal tube (ET tube), which is a soft tube placed in the wind pipe, affects the incidence of vomiting after surgery. Two hundred six children between the ages of 2 and 12 years are expected to take part in this study.

The aim of this randomized trial is to assess the efficacy of preventive analgesia using different peribulbar blocks (PBB) under SPI-guided anaesthesia for vitreoretinal surgery (VRS), presence of PONV (postoperative nausea and vomiting) and oculocardiac reflex (OCR) and compare Numerical Rating Scale (NRS) with Surgical Pleth Index (SPI) for monitoring pain perception postoperatively. Patients will receive general anaesthesia combined with either preventive PBB using either lidocaine with bupivacaine or bupivacaine or ropivacaine

To compare early versus on demand maternal feeding after cesarean delivery regarding gastrointestinal complaints and patient's satisfaction.
