Adding Aprepitant to a Multimodal Strategy for the Prevention of Postoperative Nausea and Vomiting in High-risk Outpatient Surgical Patients

Postoperative nausea and vomiting (PONV) are a frequent and debilitating complications after surgery, affecting up to 80% of patients at high risk in the absence of prophylaxis. Despite the rigorous application of the recommendations from the American Society of Anesthesiologists (ASA) at CHUM, a recent local study reveals a prevalence of 25% PONV at home after outpatient surgery. However, the therapeutic options at home remain limited. This study aims to evaluate if the addition of 40 mg aprepitant to a multimodal strategy for preventing PONV improves clinical outcomes in high-risk patients undergoing outpatient surgery.

Efficacy of Non-weight Based, Low Dose Dex-Dex Adjuncts in Prolonging Peripheral Nerve Blocks

The goal of this clinical study is to improve upon the standard practice of utilizing nerve blocks to enhance the satisfaction of patients undergoing shoulder, or foot and ankle surgery regarding their quality of pain control, the duration of their nerve blocks, as well as the avoidance of opioid medications and subsequently their undesirable side effects. The researchers hypothesize that dexmedetomidine and dexamethasone (Dex-Dex) will work synergistically as adjuncts in a low, non-weight based formula. This would allow the investigators to improve patient satisfaction by providing them with a superior means of pain control that is longer in duration with a decreased probability of unwanted side effects. The proposed clinical study will be a prospective, randomized control trial.

ENDOblock: Bilateral Superficial Cervical Blocks With Local Wound Infiltration in Thyroid Surgery

This is a single center, prospective, double-blinded randomized controlled trial comparing the efficacy of bilateral superficial cervical plexus blocks (BSCPB) with local wound infiltration vs placebo with local wound infiltration in reducing thyroid surgery postoperative pain. Primary outcomes assessed are post operative pain, quality of life/recovery, post operative nausea/vomiting and opioid use.

Autonomic Neural Blockade in Bariatric Surgery

The purpose of this research is to evaluate if autonomic nerve block (ANB- blocking pain and nausea signals) decreases pain and anti-nausea medication requirements as well as the experience of pain/nausea during the first 72 hours after sleeve gastrectomy or gastric bypass surgery. Participants will be randomly assigned either to the standard of care or the ANB group before surgery. As part of standard of care, in both groups, laparoscopic bariatric surgery will be initiated with local anesthetic injected into the abdominal wall. In the ANB group, participants will be given an additional injection of local anesthetic medication to block nerves on and around the stomach.

Side Effects of a Single Shot Intrathecal Morphine in Clinical Practice, a Retrospective Analysis

ITM has the potential to be a powerful tool for multimodal postoperative pain management, understanding, preventing and managing its side effects is crucial for upturn of patient safety and comfort. This retrospective audit will therefore be focused on the most reported side effects in daily clinical practice in patients having received ITM. The results of this study may lead to new insights into the clinically relevant risk-benefit balance of ITM and will contribute to the optimisation of its use in clinical practice.

Comparison of Gastric Volume in I-gel and ProSeal Laryngeal Mask Airways

This study was planned to compare the gastric insufflation volume between i jel and ProSeal laryngeal mask airway (LMA) and its relationship with the oropharyngeal sealing pressure and the incidence of postoperative complications in patients undergoing urological surgery.

Frequency of Occurrence and Risk Factors of Postoperative Nausea and Vomiting During Elective C-section Under Spinal Anesthesia With Preventive Medication

The aim of this study is to learn about the incidence and risk factors of nausea and vomiting during planned caesarean section under spinal anesthesia. The main question it aims to answer is : What are the incidence and risks factors of postoperative nausea and vomiting (NV) during planned caesarean section under spinal anesthesia with administration of intrathecal morphine and multimodal antiemetic prophylaxis ? Patients who will be managed according to the standard protocol in use in the department will have to answer specific questions about NV in the post-interventional recovery room and on 2 further visits in the first 24 hours post-caesarean section.

Aprepitant Treatment to Prevent Postoperative Nausea and Vomiting in Children Undergoing Scoliosis Surgery

This research trial will measure how useful Aprepitant is in preventing nausea and vomiting in children having surgery to correct scoliosis (curvature of the spine).

The Effect of Cold Steam Application on Nausea and Vomiting

The aim of this study was to determine the effect of cold vapour applied to patients undergoing laparoscopic abdominal surgery primarily on nausea and vomiting and secondarily on antiemetic requirement, patient satisfaction and thirst. H1: Cold steam application after surgical intervention has a decreasing effect on postoperative nausea. H2: Cold steam application after surgical intervention has a decreasing effect on postoperative vomiting. H3: Cold steam application after surgical intervention reduces the need for antiemetic drugs. H4: Cold steam application after surgical intervention has a satisfactory effect on reducing nausea and vomiting.

Impact of Intrathecal vs Intravenous Dexmedetomidine

The purpose of this research is to evaluate the impact of intrathecal dexmedetomidine in comparison with intravenous route in patients undergoing cesarean section. Alternate hypothesis :Dexmedetomidine is more effective when given intrathecally as adjuvant to bupivacaine in elective cesarean section Null Hypothesis: Dexmedetomidine is more effective when given intravenously as adjuvant to bupivacaine in elective cesarean section Study Design: Randomized controlled trial Study setting: Watim General Hospital Study Duration: 18 months after synopsis approval Sampling technique: Simple random sampling Sample Size: Using the Open Epi program, a sample size of 60 patients (30 in each group) was determined with a 95% confidence interval and 80% power. Inclusion Criteria: * Pregnant women between ages 18-35 years * Belongs to ASA class I or II * Subjected to elective C-section Exclusion Criteria: * Any history of gastrointestinal disease diabetes, thyroid disease, hypertension, obesity, or anemia * History of alcohol or drug abuse; * Major complications of pregnancy * Patients have contraindication to spinal block or allergic to any of drug

An Economic Study of HSK21542 Injection for Prevention of Postoperative Nausea and Vomiting

This study analyzed the efficacy and safety results of HSK21542 injection for the prevention of postoperative nausea and vomiting in a multicentre, randomized, double-blind, placebo-controlled dose-exploration study, as well as the real-world clinical routine use of troisisone and other (not limited to other setron drugs) for the prevention of postoperative nausea and vomiting and related adverse reaction treatment data. It was transformed into an effect indicator, and the possible costs involved in the study were analyzed, reasonable price parameters of HSK21542 injection were set, and the economic value of HSK21542 was explored.

A Risk Prediction Model of Postoperative Nausea and Vomiting in Patients With Liver Cancer

PONV management has been recommended as a necessary part of enhanced recovery protocols during the perioperative period, and PONV risk assessment is, therefore, a necessary first step in determining the number of medications or strategies for prophylaxis and treatment by considering the number of modifiable and non-modifiable risk factors. However, the external validity of two commonly-used PONV prediction models for patients undergoing liver surgery is unsatisfied, and need to be updated for liver cancer populations to better inform personalized perioperative care regime and individualized decision-making in clinical practice.
