Active clinical trials for "Postoperative Nausea and Vomiting"

Patients aged between 20 and 70 years, ASA physical status I-III, and scheduled for laparoscopic cholecystectomy under general anaesthesia will be enrolled in the study. Patients will be randomized to the preemptive group to receive an antiemetic regime 1h before the start of surgery or to the intraoperative group to receive the same antiemetic drugs in the same doses intraoperatively, 30 min before the end of surgery. In the operating room standard monitoring and a standardized anesthetic technique will be implemented in all patients. Nausea, vomiting, retching and PONV (cumulative) will be recorded at PACU, at 4h, 8h and 24h postoperatively. Pain scores assessed by NRS (numerical rating scale) will be recorded at the same time points. Also, when patients received fluids and solid food by mouth will be recorded.

Pediatric research in the management of nausea has been limited by the absence of a reliable method to quantify the intensity of this subjective symptom. In adults, the visual analog scale (VAS) is an accurate tool, but this has not been shown to be reliable in young children. A scale is a series of points made on a line that will be used for measurement; a mark on the far left of the line shows little pain and the mark on the far right means alot of pain.

The purpose of this study is to determine whether continuous infusion of palonosetron after its prophylactic single injection can further reduce the incidence of postoperative nausea and vomiting in patients undergoing gynecological laparoscopic surgery.

Postoperative nausea and vomiting ( PONV ) is one of the common complications after general anesthesia while genetic factors may play an important role in Postoperative nausea and vomiting. In this study, the investigators investigated the relationship between gene polymorphism ( such as single nucleotide polymorphism ) of the gene HTR3A ( 5-hydroxytryptamine receptor 3A ), HTR3B ( 5-hydroxytryptamine receptor 3B ), HTR3C ( 5-hydroxytryptamine receptor 3C ) and TACR1 ( tachykinin receptor 1 ) etc. with nausea and vomiting after general anesthesia. Simultaneously, the investigators explored the influencing factors of nausea and vomiting.

Patients undergoing laparoscopic sleeve gastrectomy will be randomized into 2 groups. In one group, a staple line inversion with a running suture of Polypropylene will be performed. In the second group, the gastric section will be performed with a stapler with preloaded buttress material Postoperative nausea and vomits during the first 24 hours will be investigated.

Point-of-care gastric ultrasound will be used to measure stomach contents postoperative in patients who underwent colorectal surgery. Stomach volume and status (empty or full) will be compared retrospectively to the standard clinical criteria for diet advancement to determine if stomach volume via ultrasound is associated with successful diet advancement, nausea/vomiting, nasogastric tube replacement, length of stay, and other clinical outcomes. Clinicians performing clinical care will be blinded to the ultrasound exam results.

Pediatric research in the management of nausea has been limited by the absence of a reliable method to quantify the intensity of this subjective symptom. In adults, the visual analog scale (VAS) is an accurate tool, but this has not been shown to be reliable in young children. By default the most common objective outcome measure used in pediatric studies has been the incidence and number of emetic episodes. This measure, however, correlates poorly with the somatic subjective symptom of nausea.

Patients with BMI >35 and chronic diseases or BMI >40 will be scheduled to receive Laparoscopic Sleeve Gastrectomy (LSG). Two groups are planned according to receive Enhance recovery after surgery (ERAS) protocol or not. All participants will receive standard LSG. Participants of ERAS will receive anesthesia and post-surgical nutrition protocol which are determined for ERAS. All patients will be checked for status of pain with VAS score, nausea and vomiting with PONV score at postoperative 2nd hour, 12th hour. In ERAS group liquid oral intake will be started between postoperative 2nd and 4th hours. In no ERAS group liquid oral intake will be started in the morning of postoperative first day. The patients who provides discharge criterias will be discahrged. these criterias are; To provide adequate pain relief with paracetamol and nonsteroidal painkillers, No wound problem, No complications after surgery, Pulse rate <90 beats / min, temperature ≤ 37 · 5 ° C, respiratory rate, <20 breaths / minute, To be able to mobilize easily, To be able to drink 1 liter of water after surgery. Emergency admissions of the participants within a month after surgery will be recorded.

Postoperative nausea and vomiting (PONV) is a distressing adverse effect that may result in postoperative complications including bleeding, wound dehiscence, aspiration pneumonitis, as well as fluid and electrolyte imbalances Incidence of PONV after general anesthesia is about 30% in all post-surgical patients but up to 80% in high-risk patients despite advances in anesthetics and anesthesia techniques

Hypothesis: Dexamethasone reduces postoperative emesis in thyroidectomy and mastectomy patients.
