Postoperative nausea and vomiting after general anesthesia for oral and maxillofacial surgery

Abstract

BackgroundPostoperative nausea and vomiting (PONV) is one of the most common postoperative complications. Despite this, few papers have reported the incidence and independent risk factors associated with PONV in the context of oral and maxillofacial surgery (OMFS). Therefore, we sought to determine the incidence of PONV, as well as to identify risk factors for the condition in patients who had undergone OMFS under general anesthesia.MethodsA total of 372 patients' charts were reviewed, and the following potential risk factors for PONV were analyzed: age, sex, body mass index, smoking status, history of PONV and/or motion sickness, duration of anesthesia, amount of blood loss, nasogastric tube insertion and retention and postoperative opioid used. Univariate analysis was performed, and variables with a P-value less than 0.1 were entered into a multiple logistic regression analysis, wherein P-values < 0.05 were considered significant.ResultsThe overall incidence of PONV was 25.26%. In the multiple logistic regression analysis, the following variables were independent predictors of PONV: age < 30 years, history of PONV and/or motion sickness, and anesthesia duration > 4 h. Furthermore, the number of risk factors was proportional to the incidence of PONV.ConclusionsThe incidence of PONV in patients who have undergone OMFS varies from center to center depending on patient characteristics, as well as on anesthetic and surgical practice. Identifying the independent risk factors for PONV will allow physicians to optimize prophylactic, antiemetic regimens.

Effect of Body Mass Index on Postoperative Nausea and Vomiting: Propensity Analysis

“…However, whether obesity is a risk factor for PONV is controversial. A relatively high body mass index (BMI) may promote PONV [8,11], but the opposite effect has also been reported [12][13][14]. Others have found that BMI is not a risk factor for PONV [15,16].…”

The Effect of Preoperative Zintoma Capsule on Postoperative Nausea and Vomiting After Laparoscopic Cholecystectomy

“…Postoperative nausea and vomiting (PONV), as one of the most common and most annoying complications after laparoscopic cholecystectomy, occurs in more than 40% - 77% of the cases ( 1 ). PONV causes aspiration, hypoxia, bleeding, suture rupture, patient discomfort, increased hospital stay, and increased hospital costs ( 2 ). Preoperative drugs that are used intravenously to prevent PONV include endostenone, troposterone, granistorone, dilustran, metoclopramide, and perphenazine.…”

Pediatric dentist accessibility and post-operative complications of laryngeal mask airway versus nasotracheal intubation in full mouth rehabilitation under general anaesthesia: a randomised controlled trial

“…Further, the incidence of PONV was similar in NTI and LMA groups. Postoperative nausea and vomiting might be more affected by the anaesthetic drug used [26][27][28] , or the type of surgery performed rather than by the airway management technique. It should be noted that all children in both groups received an antiemetic intravenously during the operation, which might explain the decreased incidence of nausea and vomiting in both groups.…”
