Effects of Different Inspiratory:Expiratory Ratios on Respiratory Function and Recovery in Pediatric Dental Procedures Under General Anesthesia

What this Trial Is About

Researchers are evaluating the effects of different inspiratory to expiratory (I:E) ratios during mechanical ventilation in children aged 2 to 12 years undergoing dental procedures under general anesthesia. This observational study compares the routine I:E ratio of 1:2 with a 1:3 ratio, aiming to see how these settings affect respiratory function and recovery quality during emergence from anesthesia. The goal is to find the best ventilation strategy to improve safety and comfort for pediatric patients during this process. All participants will receive standard anesthesia and dental care without any additional interventions. The study groups include children who emerge from anesthesia earlier than planned without preparation, those ventilated with an I:E ratio of 1:2, and those ventilated with an I:E ratio of 1:3 during the last phase of the procedure. The I:E ratio is adjusted 20-30 minutes before the end of surgery to help transition to spontaneous breathing. Throughout the study, vital signs and respiratory parameters such as heart rate, blood pressure, oxygen saturation, carbon dioxide levels, respiratory rate, and airway pressure will be monitored. Researchers will assess respiratory quality after extubation using a non-invasive scoring system and track recovery outcomes including physical responses, airway complications, anxiety, delirium levels, and discharge times. All data are recorded without altering routine clinical care, and the total follow-up covers emergence and recovery periods.
