Introduction: Due to the fact that postoperative pain can cause complications and patient dissatisfaction, and since studies on the effect of sodium bicarbonate solution on postoperative pain are limited, the present study aimed to determine the effect of sodium bicarbonate solution on pain score. Material and Methods: In this study, which was the result of a clinical experiment during ۲۰۱۹, ۵۰ patients who were candidates for elective surgery with midline laparotomy were examined. At the end of the operation, the patients underwent intraperitoneal lavage with ۷% sodium bicarbonate solution and normal saline. Pain intensity was assessed using a visual pain scale.Results: The mean pain score ۲,۴,۶,۱۲,۱۸ and hours after the intervention was significantly lower in the intervention group than the control group (P=۰.۰۰۱)Conclusion: Using a combination of sodium bicarbonate solution and normal saline for intraperitoneal lavage is a simple and uncomplicated method that can help reduce patients' pain for up to ۲۴ hours after surgery and reduce the need for sedation.
