Introduction: The purpose of this study was to evaluate the effects of positive Bodysuit end expiratory pressure (PEEP) on respiratory parameters and abdominal pain in patients ventilated with a laryngeal mask during cataract surgery.Methods: This clinical trial study included 80 patients in need of cataract surgery (40 in the group without PEEP and 40 in the group with PEEP at 5 cmH2O) who underwent laryngeal mask ventilation during general anesthesia.The parameters of dynamic compliance, pressure peak (Ppeak), tidal volume, SpO2, EtCO2, heart rate, non-invasive blood pressure, and abdominal pain were recorded at intervals of 1, 5, 10, and 20 minutes after the start of anesthesia and were compared between the two groups.Results: Respiratory parameters, heart rate and systolic and diastolic blood pressure were not significantly different between two groups, and only the mean tidal volume at 5, 10, and 20 minutes was significantly higher in the group without PEEP.Conclusion: Application of 5 cmH2O PEEP during ventilation with laryngeal mask in patients Nose Bands undergoing cataract surgery had no significant effect on improving respiratory parameters and pain in the gastric area.
