PONV

The invistigators hypothesized that a protocolized OFA technique would lower the occurance of PONV in patients undergoing thoracoscopic lung surgery compared to standard opioid-based anaesthesia.

The goal of this observational study is to learn how often postoperative nausea and vomiting occur in adults undergoing nasal surgery under general anesthesia and to identify factors associated with these events. The study will also describe other postoperative complications and factors that may affect recovery. The main questions it aims to answer are: * How many participants experience nausea, retching, or vomiting within 24 hours after surgery? * Which patient characteristics, anesthesia-related factors, surgical factors, and perioperative medications are associated with postoperative nausea and vomiting? * What other postoperative complications and nasal-related symptoms occur after surgery? Approximately 1,000 adults undergoing nasal surgery under general anesthesia at three hospitals in China will be enrolled. This is an observational study, and participation will not change the anesthesia, surgery, medications, or other medical care selected by the treating clinical team. Participants will: * Complete assessments before surgery about their medical history, previous nausea or vomiting, anxiety, sleep, and recovery status * Receive routine anesthesia and surgical care * Be assessed for nausea, retching, vomiting, pain, nasal discomfort, and other complications during the first 24 hours after surgery * Complete follow-up assessments after surgery, including follow-up by telephone after discharge, for up to 6 months The study will use information from participant questionnaires, medical records, anesthesia records, and postoperative follow-up assessments.

The proposed research will utilize electroacupuncture, a type of needleless acupuncture that uses electrostimulation, in a randomized, double blind study, to evaluate the incidence of post-operative nausea and vomiting (PONV) in patients undergoing spinal surgeries with the transcutaneous electrical acupoint stimulation (TEAS) compared to patients without TEAS.

The goal of this clinical trial is to learn if intragastric administration of lidocaine can reduce postoperative nausea and vomiting in obese patients undergoing laparoscopic sleeve gastrectomy. The main question it aims to answer is: Does administering 0.5% lidocaine via an orogastric tube reduce the incidence of postoperative nausea and vomiting (PONV) in the post-anesthesia care unit and within the first 24 hours after surgery compared to a placebo (normal saline)? Researchers will compare the Lidocaine Group to the Placebo Group to see if the intervention lowers the PONV incidence. Participants will: * Receive the assigned study solution (either 0.5% lidocaine 20ml or normal saline 20ml) through an orogastric tube upon surgery completion and before extubation. * Have their gastric tube clamped for 5 minutes to ensure mucosal exposure before removal. * Undergo standardized total intravenous anesthesia and perioperative management according to the study protocol. * Be assessed for nausea, vomiting, and other outcomes at specified time points postoperatively in the recovery room and at 6, 12, and 24 hours.

The purpose of this research is to study whether adding an FDA approved medication called aprepitant (a medication given to patients like you to reduce or eliminate nausea and vomiting) to the usual treatment to prevent nausea and vomiting given to patients during knee replacement surgery helps more patients go home on the same day of surgery (before midnight) by eliminating nausea and vomiting.

This single-center, double-blind, randomized controlled trial aims to determine whether oliceridine for patient-controlled intravenous analgesia (PCIA) can significantly reduce the incidence of postoperative nausea, an opioid-related adverse reaction, compared to sufentanil PCIA in patients undergoing cerebellopontine angle (CPA) region surgery. A secondary objective is to compare the postoperative analgesic effects between the two drugs. The study plans to enroll 174 patients (with a calculated sample size of 164 plus 5% for attrition). The primary outcome is the incidence of nausea within 6-48 hours postoperatively. Secondary outcomes include pain scores at rest and during movement within 48 hours, and other exploratory outcomes such as vomiting incidence, time to first flatus/defecation, and gastrointestinal function scores.

This study aims to focus on patients undergoing gynecological laparoscopic surgery and further evaluate the role of amisulpride in preventing postoperative nausea and vomiting in these patients.

This prospective, randomized controlled study aims to evaluate the efficacy and safety of electroacupuncture combined with 5-HT3 receptor inhibitor for preventing postoperative nausea and vomiting (PONV) in high-risk patients undergoing thoracoscopic lung cancer surgery. The primary outcome is the incidence of PONV within 24 hours after surgery.

Laparoscopic cholecystectomy is a commonly performed minimally invasive surgical procedure; however, postoperative pain, nausea, and delayed recovery remain clinically relevant problems. Glucocorticoids such as dexamethasone are widely used in perioperative care for the prevention of postoperative nausea and vomiting and as part of multimodal analgesia strategies. This prospective randomized controlled trial aims to compare the effects of moderate- and high-dose intravenous dexamethasone administered intraoperatively on postoperative recovery in patients undergoing elective laparoscopic cholecystectomy. The primary outcomes include postoperative nausea and vomiting, inflammatory markers (CRP and WBC), and Quality of Recovery-15 (QoR-15) scores. Secondary outcomes include postoperative pain scores, intraoperative remifentanil consumption, postoperative opioid consumption, and adverse events.

Regional anesthesia is a technique in which a local anesthetic is injected near a nerve or spinal cord to block sensation, motor stimulation, and pain. In this study, an ultrasound-guided paravertebral block will be used, with careful consideration of all positive and negative factors and possible complications. A thoracic paravertebral block is performed by inserting a needle into the intercostal spaces on the back, approximately 4 cm lateral to the spine. Many studies support excellent pain control with this technique, during and after surgery in thoracic and abdominal surgery. Investigators aim to achieve faster patient mobility after surgery, rapid recovery of bowel function, reduced nausea and vomiting, and maximum pain control. The use of opioids, which can additionally cause respiratory suppression and drowsiness, is avoided. At any time in case of need to switch from laparoscopic to open surgery, equally adequate anesthesia and postoperative analgesia are ensured without the need to change the approach to the same. In this study, the basic scientific assumption (hypothesis) of the researchers is that non-opioid anesthesia with thoracic paravertebral block provides adequate pain control during and long-term after the surgical procedure, without the side effects of opioid anesthesia. The main goal of the study is to determine which type of anesthesia results in the best pain control and most significantly reduces complications of anesthesia and surgery in overweight patients who are scheduled for laparoscopic longitudinal gastrectomy and partial/total gastrectomy.

Postoperative nausea and vomiting (PONV) are the most common complications that can occur after general anesthesia. Postoperative use of opioids and morbid obesity have been reported as risk factors of PONV. In this study, the investigators aimed to compare the degree of postoperative side effects and pain control when an intravenous patient-controlled analgesia combining fentanyl and ketorolac via a dual-chamber device was provided to participants undergoing laparoscopic sleeve gastrectomy.

Sugammadex is a medication used for reversal of muscle relaxation during procedures under general anesthesia. It works by encapsulating muscle relaxant molecules with a steroid ring in its structure. On the other hand, postoporative nause and vomiting (PONV) is an adverse outcome during anesthesia. PONV can be prevented with pharmacologic agents such as ondansetron and dexamethasone. Dexamethasone is a steroidal agent that can interact with sugammadex. In theory, this interaction could lead to reduced effectiveness of sugammadex. In fact, several studies have explored this interaction. However, the effect of sugammadex on the antiemetic effect of dexamethasone has not been evaluated. This study intends to evaluate this interaction.

The study is primarily an exploratory study of quality registry data for a swedish national cohort of patients who have undergone gallbladder surgery or ERCP, with the aim of investigating the occurrence of pain and PONV (Postoperative Nausea and Vomiting) after gallbladder surgery. Furthermore, the investigators will explorer if there are factors related to the patient or the surgical procedure that are associated with a higher risk of PONV or pain.
