Evaluation and comparison of reciting the Quran with white noise on depth of anesthesia and post-operative complications in vitrectomy surgery

Previous studies have shown that reciting the Quran can reduce anxiety, pain and sympathetic activity. One of the criticisms of these studies was the lack of an appropriate control group. In this study, white sound consisting of all wavelengths audible to humans was used as a control group.

Fifty patients who were candidates for vitrectomy under general anesthesia included in the study. These patients were randomly divided into two groups: Quran Group and White Noise Group. After obtaining informed consent, the associated sound was played to the patients after induction of anesthesia. The two groups were compared in terms of propofol use as an anesthetic to maintain a BIS of about 50, as well as pain, nausea and vomiting.

The average consumption of propofol in the Quran group was significantly lower than the white voice group (P-value = 0.05). Also, the rate of nausea and vomiting was lower in the Quran group, but the amount of pain was not significantly different between these two groups.

The reciting of the Quran can reduce the need for anesthesia and reduce postoperative nausea and vomiting.
