Brief Summary:
The primary objective of our study is to compare the effects of different flow rates of the routinely used inhalation agent, sevoflurane, on postoperative recovery times in pediatric patients undergoing elective laparoscopic surgeries. Our secondary objectives are to evaluate the impact of different flow rates on hemodynamic parameters, ventilation parameters, and costs.
Detailed Description:
Low-flow anesthesia is a technique in which at least 50% of the exhaled gas is returned to the system through rebreathing. When using modern rebreathing systems, low-flow anesthesia can be defined if the fresh gas flow rate is reduced below 2 L/min. This anesthesia method involves using an anesthesia system with rebreathing capabilities, where carbon dioxide is removed from the gas mixture exhaled by the patient, and then at least 50% of the fresh oxygen flow, along with volatile anesthetics sufficient to meet the body's metabolic requirements, is returned to the patient.
The application of low-flow anesthesia reduces the consumption of anesthetic gases, decreases the cost of anesthesia, minimizes contamination of the working environment and atmosphere with anesthetic gases, preserves the respiratory physiology of the patient, and minimizes heat and humidity loss by heating and humidifying the gases delivered to the patient, thereby better maintaining the physiology of the trachea and bronchial environments. The heating of gases is also beneficial for maintaining body temperature and preventing postoperative hypothermia. Additionally, due to the requirement for close monitoring, anesthesia safety is increased .
In pediatric patients, due to their different anatomical and physiological characteristics compared to adults, the application of low fresh gas flow anesthesia can be more challenging. This is especially the case when using uncuffed endotracheal tubes, where leaks may occur in the respiratory system, and the breathing circuits used may increase dead space. However, studies have shown that with appropriate techniques and adequate monitoring, these potential problems can be prevented, and low-flow anesthesia can be safely applied in children with close monitoring.
In our study, the investigators aim to compare the effects of different flow rates on postoperative recovery, hemodynamic factors, and costs in children, and to demonstrate that low-flow anesthesia can be applied as safely as high-flow anesthesia in pediatric patients. The investigators believe our study will contribute significantly to the literature on this topic.
