BACKGROUND The incidence of postoperative nausea and vomiting (PONV) after intrathecal morphine is high. Ramosetron is a 5-HT₃ antagonist that has been shown to reduce PONV in general anesthesia. The objective of this study was to evaluate the efficacy of Ramosetron in preventing PONV MATERIAL AND METHOD: 165 patients undergoing elective gynecological surgery under spinal anesthesia were random...

BACKGROUND Under the assumption that postoperative nausea and vomiting (PONV) may occur after total hip arthroplasty (THA) regardless of the anesthetic technique used, it is not clear whether general (GA) or spinal (SA) anesthesia has higher causal effect on this occurrence. Conflicting results have been reported. METHODS In this observational study, we selected all elective THA interventions...

Purpose: Prevention of postoperative nausea and vomiting (PONV) for orthognathic surgery is very important because of intermaxillary fixation. The aim of this study is to compare the eff ic iency of dexamethasone and metoclopramide in prevention of PONV. Materials and Methods: 22 patients age 15-50, ASA I-II, undergoing orthognathic surgery were randomly allocated in two groups. Group D n=11 –u...

BACKGROUND Refractory postoperative nausea and vomiting (PONV) requiring repeated treatment with antiemetic drugs is a miserable experience for the patient that may substantially increase the cost of care. As risk stratification may aid in prophylaxis and treatment, we explored risk factors for severe PONV in patients enrolled in a large international, randomized controlled trial (the ENIGMA tr...

Background This study investigated plasma concentrations of substance P (SP) in patients undergoing general anesthesia (GA) and postoperative nausea and vomiting (PONV). This prospective, observational, cohort study included 23 patients who underwent scheduled surgery under general anesthesia. Blood was collected from the radial artery at predetermined time points (15-30 mins prior anesthesia, ...

Postoperative nausea and vomiting (PONV) are still common following surgery. This is not only distressing to the patient, but increases costs. The thorough understanding of the mechanism of nausea and vomiting and a careful assessment of risk factors provide a rationale for appropriate management of PONV. Strategy to reduce baseline risk and the adoption of a multimodal approach will most likel...

relief and for ambulation. Any study about PONV that includes the routine use of opioids may be trying to get the right answer by asking the wrong question. Avoiding the routine use of opioids, Friedberg recently published a 0.6% PONV rate in a series of 1,264 patients, one third of whom had PONV with the use of previous opioid-based anesthetics. Was Pogo right after all? Have we met the enemy,...

New antiemetic drug developments, formulations, guidelines, risk evaluation, and controversies have occurred in the area of postoperative nausea and vomiting (PONV). These developments have helped improve our understanding of the prevention and treatment of PONV in the postanesthesia care unit and after discharge home or to the hospital ward. Antiemetic drug research has resulted in the introdu...

Postoperative nausea and vomiting (PONV) is among the most important concerns of patients undergoing surgery. The incidence ranges from 30% to 70%. The incidence of PONV correlates with a number of risk factors a patient possesses. Patient-related risk factors in adults are: female gender, history of PONV, duration of surgery > 60 min, nonsmoking status, history of motion sickness, and postoper...

Postoperative nausea and vomiting (PONV) is prevalent in surgical patients with known risk factors: general anesthesia, female, nonsmoker, motion sickness history, and PONV history. Common treatment involves ondansetron; however, the effects are short-lived, and supplemental medication may be required. Meclizine, a long-acting drug with a low side-effect profile, may be ideal in combination wit...
