Objective: In sedation practices, respiratory monitoring, particularly for endoscopic procedures, remains crucial due to the risk of respiratory complications. Despite standard monitoring recommendations, significant hypoventilation may occur, leading to adverse events. Integrated pulmonary index® (IPI) offers comprehensive respiratory status assessment, yet its utility in endoscopic sedation remains unclear. Methods: A prospective, double-blind, randomized controlled trial was conducted at Kartal City Hospital between July and September 2022. Patients aged 18-80 undergoing endoscopic procedures were randomized into standard monitoring (Group 1) or capnography with IPI monitoring (Group 2). Both groups received standard monitoring, whereas Group 2 additionally had capnography monitoring. Results: Of the 200 patients included, no significant differences were observed in demographics or procedure types between groups. Apnea duration was significantly lower in Group 2 (IPI group). Group 2 showed higher peripheral oxygen saturation (SpO2) and IPI values at specific intervals compared to Group 1. However, the occurrence of apnea did not significantly differ between groups. Conclusion: While capnography with IPI monitoring showed advantages in reducing apnea duration and maintaining higher SpO2 levels, these differences were not clinically significant. Capnography’s role as an adjunct to standard monitoring in preventing respiratory complications during endoscopic procedures needs further evaluation, considering its cost implications.
