Effects of Aromatic Solution Applied After Surgery

Today, surgical applications are used to solve many health problems. In order for the surgical intervention to take place, anesthesia applications are often required. Complications such as sore throat, thirst and nausea and vomiting may occur as a result of trauma, local irritation and inflammation of the airway mucosa during anesthesia and tracheal intubation. These complications are in the postoperative period; It may cause delayed oral fluid intake, prolonged dehydration, oral odour, and increased risk of aspiration, hematoma and wound dehiscence due to retching and vomiting, all of which may lead to delayed discharge and increased cost. Aromatherapy, one of the non-pharmacological applications, is frequently applied in reducing postoperative complications and its effectiveness is stated. In this study, the aromatic solution applied after the surgery; It was planned to examine the effect on sore throat, thirst, nausea-vomiting. In addition, the multimodal synergistic effect of lavender oil and ginger oil used in the aromatic solution to be prepared will be utilized. As a result of this study, the effectiveness of the aromatic solution application to be applied to the patients in the postoperative period and the benefits and benefits of the patient's recovery process will be determined. Thus, effective application can be made for the entire postoperative period. It is thought that this study to be conducted will be a guide for future studies on the patient group.

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.

The Effects of IV vs Oral Dexamethasone on Postoperative Nausea, Vomiting, and Pain

The hypothesis being tested in this study is that perioperative oral administration of dexamethasone, when compared to intravenous (IV) administration, offers a similar reduction in postoperative nausea and vomiting (PONV), and reduction in postoperative pain in pediatric patients undergoing tonsillectomy with or without adenoidectomy and/or tympanostomy tube placement. The specific aim of this study is to demonstrate non-inferiority of oral dexamethasone when compared to IV dexamethasone, given that there is currently a severe, sudden, and world-wide shortage of IV dexamethasone given its recent use in treating patients with covid19 disease.

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.

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.

Association Between Pain Catastrophizing and PONV in Laparoscopic Cholecystectomy Patients

This study aims to explore whether patients' tendency to exaggerate or focus on pain (pain catastrophizing) is related to experiencing nausea and vomiting after surgery. The study will include patients undergoing laparoscopic cholecystectomy. Before surgery, patients will answer questions measuring pain catastrophizing and rate their pain during intravenous cannulation. Nausea and vomiting will be assessed at various times during the first 24 hours after surgery. The results may help better understand how psychological factors affect postoperative symptoms.

Catheter Redosing of Autonomic Neural Blockade After Sleeve Gastrectomy

Postoperative visceral pain and autonomic symptoms after laparoscopic sleeve gastrectomy may reappear earlier in selected high-risk patients despite standard intraoperative autonomic neural blockade (ANB). Temporary in situ catheter placement permits postoperative ANB redosing when breakthrough visceral symptoms occur. This prospective single-arm observational study will evaluate the feasibility, safety, and clinical effectiveness of temporary ANB catheter placement and selective postoperative redosing in high-risk patients undergoing laparoscopic sleeve gastrectomy.

Application of Multimodal Intervention in the Prevention of Postoperative Nausea and Vomiting After Gynecological Laparoscopic Surgery

1. Background Postoperative nausea and vomiting (PONV) is a common complication after general anesthesia, with an incidence as high as 80% in gynecological laparoscopic surgery. Transcutaneous electrical acupoint stimulation (TEAS) has shown potential as a non-invasive, side-effect-free intervention. Combining pharmacological agents (dexamethasone or amisulpride) with TEAS may provide a synergistic preventive effect, aligning with enhanced recovery after surgery (ERAS) principles. 2. Study Objectives To evaluate the preventive effect of TEAS on PONV in patients undergoing gynecological laparoscopic surgery, compared with sham stimulation. To explore the synergistic effect of dexamethasone or amisulpride when combined with TEAS, and to optimize PONV prevention strategies. To assess the impact of multimodal intervention on postoperative recovery quality, length of hospital stay, and patient satisfaction. To evaluate the safety of the combined interventions and record any adverse events. 3. Study Design Design type: 2×2 factorial, randomized, double-blind (participants, outcome assessors, and data analysts blinded to group assignment). Randomization: 1:1:1:1 allocation using an online randomization tool. 3.1 Study Groups Group Intervention A TEAS + Dexamethasone B TEAS + Amisulpride C Sham stimulation + Dexamethasone D Sham stimulation + Amisulpride 3.2 Participants Inclusion criteria: Age 18-65 years; ASA physical status I-II; scheduled for elective gynecological laparoscopic surgery (e.g., ovarian cystectomy, myomectomy) under general anesthesia; willing to provide informed consent. Exclusion criteria: Severe cardiac, hepatic, renal, or pulmonary disease; allergy or skin disease at TEAS application site; Receipt of antiemetics within 24 h before surgery; Implanted cardiac pacemaker, cardioverter-;pregnancy or lactation; vulnerable populations (e.g., critically ill, psychiatric disorders, cognitive impairment, illiteracy); any condition deemed unsuitable by the investigator. 3.3 Interventions A wearable transcutaneous electrical acupoint stimulation (TEAS) wristband will be applied to the P6 (Neiguan) acupoint on the dominant upper extremity. The P6 acupoint is located approximately 3-5 cm proximal to the distal wrist crease, between the tendons of the flexor carpi radialis and palmaris longus. The device integrates the stimulating electrodes within the wristband and does not require external adhesive electrodes. TEAS or sham stimulation will be administered at three time points: 30 minutes before surgery and 24 and 48 hours after surgery, with each session lasting 30 minutes. Dexamethasone 5 mg (off-label for PONV; approved for inflammatory/allergic conditions). Amisulpride 5 mg. 3.4 Outcome Measures Primary outcomes (0-48 h postoperatively): PONV incidence (proportion of patients with nausea, vomiting, or retching). PONV severity (0 = none, 1 = nausea only, 2 = vomiting/retching, 3 = refractory nausea/vomiting). Secondary outcomes: Recovery quality: time to first flatus, first ambulation, hospital stay, bowel function recovery. Patient satisfaction: Visual Analogue Scale (VAS, 0-10) and QoR-15 score (0-150). Rescue antiemetic use. Management needs for severe PONV. Postoperative pain (VAS at rest and on movement) and opioid consumption. Device-related adverse events (skin irritation, burning, allergy). Drug-related adverse events (e.g., hyperglycemia, hypotension, headache, dizziness, QT prolongation). Intraoperative hemodynamics and postoperative complications (e.g., infection, shivering, urinary retention). 3.5 Follow-up Schedule Postoperative day 1 (24 h): PONV assessment, time to first flatus and ambulation. Postoperative day 2 (48 h): PONV incidence/severity, rescue medication. At discharge: Satisfaction, hospital stay (via in-person or telephone follow-up). 4. Sample Size Calculation Assumptions: PONV incidence 50% in control groups, 30% in TEAS groups; two-sided α = 0.05; power = 80%. Each main effect level requires \~93 patients. For a 2×2 factorial design with 1:1:1:1 allocation, this translates to 47 patients per group (total 188). Accounting for a 10% dropout rate, final sample size = 212 patients (53 per group). 5. Data Management and Confidentiality Electronic Data Capture (EDC) system with unique coding (no direct identifiers). Access restricted to authorized research team members. 6. Informed Consent Written informed consent will be obtained from each participant after full explanation of the study purpose, procedures, risks, and benefits. Participants are informed of their right to withdraw at any time. 7. Adverse Event Management Dexamethasone-related AEs (transient hyperglycemia, blood pressure fluctuation, gastrointestinal discomfort, rare allergic reactions). Amisulpride-related AEs (headache, dizziness, constipation/diarrhea, QT prolongation, allergic reactions). TEA-related AEs (local skin discomfort, redness, itching, rare blisters or mild burns).

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.

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.
