End-tidal carbon dioxide monitoring during procedural sedation: A Controlled Randomized Clinical Study.

Background: basic anaesthetic procedure performed in the morning is capnography for sedation. Objectives: assess how varying oxygen flow rates impact end-tidal carbon dioxide monitoring in patients receiving procedural sedation for small gynecological operations. Subjects: One hundred twenty patients scheduled for minor gynecological operations that required procedural sedation were included in this prospective, randomized, double-blind trial. Three groups of patients were randomly assigned. The oxygen flow rate was 4 L/min for Group A and 6 L/min for Group B. In addition, the oxygen flow rate to Group (C) was 8 L/min. In order to measure EtCO2, capnography was utilized in every group. Results: End tidal CO2 levels are similar before induction and afterward (P= 0.58). The three groups showed a notable rise in CO2 levels following induction and up until 20 minutes later (P < 0.001), which was within the normal range of end tidal CO2. After 25 minutes from induction, the three groups&#039; end tidal CO2 levels returned to baseline and remained there until the end of the surgery (p > 0.05), suggesting that the physiological effects of anesthesia were clearly evident. Conversely, there is no statistically significant change over time in the intergroup disparities (p > 0.05). Conclusion:Patients undergoing small gynecological procedures under deep anesthesia were found to have non-invasive EtCO2 measurements taken by the laryngeal mask airway device independent of oxygen flow rate, according to the study&#039;s conclusion. Hypoventilation under sedation can be detected early using non-invasive EtCO2 monitoring.
