THE EFFECTIVENESS OF PULMONARY RECRUITMENT MANEUVER AND SUPPLEMENTAL OXYGEN THERAPY AND THEIR COMBINATION ON NAUSEA AND VOMITING IN PATIENTS UNDERGOING LAPAROSCOPIC CHOLECYSTECTOMY: A 2X2 FACTORIAL CLINICAL TRIAL

Patients can experience nausea and vomiting as one of the most common complications of laparoscopic cholecystectomy. Nausea and vomiting increase the risk of aspiration of stomach contents into the lungs. This study was conducted to determine the effectiveness of pulmonary recruitment maneuver and supplemental oxygen therapy and their combination on the rate of nausea and vomiting in patients undergoing laparoscopic cholecystectomy surgery.

Methods & Materials: 

This is a four-group, double-blind, 2x2 factorial clinical trial in which, 100 eligible patients were assigned to three intervention groups (pulmonary recruitment maneuver group, supplemental oxygen therapy group, pulmonary recruitment maneuver group with supplemental oxygen therapy) and one control group using simple random sampling. Data were collected using a demographic questionnaire and the Rhodes Nausea and Vomiting Severity Questionnaire. Data were analyzed using SPSS version 16.0 with significance level of less than 0.05.

There was a statistically significant difference in the mean scores of nausea, vomiting, and the final score of the nausea-vomiting criterion within 12 hours after the operation among the four groups (p<0.05). However, no significant statistical difference was seen when comparing the mean scores of nausea and vomiting criteria during 24 hours after the operation (p>0.05).

Implementing the combined method as well as pulmonary recruitment maneuver alone were more successful in managing laparoscopy-
