Purpose:
Postoperative nausea and vomiting (PONV) are one of the most common complications following anesthesia. PONV causes discomfort in various individuals. Additionally, some studies have shown that administering high concentrations of oxygen during surgery reduces PONV. Furthermore, studies have indicated that inhaling cinnamon oil extract reduces nausea and vomiting after chemotherapy. The purpose of this study was to investigate the effect of inhaling a combination of different concentrations of oxygen and cinnamon during surgery on reducing nausea and vomiting after cesarean section under spinal anesthesia.
Design:
Double-blind, randomized clinical trial.
Methods:
In this, randomized clinical trial,1 60 patients who were candidates for cesarean section under spinal anesthesia were randomly divided into 4 groups: group 1: 28% oxygen + normal saline, group 2: 28% oxygen + cinnamon leaf oil (8% v/v), group 3: 40% oxygen + normal saline, and group 4: 40% oxygen + cinnamon leaf oil (8% v/v). The information from this study, particularly the severity of nausea, was compared between the groups using the Visual Analog Scale (VAS).
Findings:
Based on the number of vomiting episodes and the severity of nausea at the end of recovery and 6 h after surgery, there was no statistically significant difference between the mentioned groups (P > 0.05).
Conclusion:
High concentrations of oxygen alone or in combination with cinnamon oil cannot reduce nausea severity during first 6 houres after a cesarean section under spinal anesthesia.
