Optic Nerve Sheath Diameter in Desflurane Anesthesia for Laparoscopic Cholecystectomy

This study focuses on understanding how different rates of desflurane anesthesia impact the optic nerve sheath diameter during laparoscopic cholecystectomy surgeries. Desflurane is a common anesthetic agent that can mildly increase blood flow and pressure in the brain. While these changes are generally well-tolerated, they need to be closely monitored to prevent complications. The study involves patients aged 18-65 years who are scheduled for elective laparoscopic cholecystectomy under general anesthesia. The research aims to improve the understanding of how anesthesia can be safely administered during such surgeries, potentially enhancing patient care and reducing risks associated with anesthesia. During the study, patients will be divided into two groups based on the fresh gas flow rate used during their anesthesia: 1 L/min or 3 L/min. The optic nerve sheath diameter will be measured using ultrasonography before, during, and after the surgery. These measurements help evaluate changes in intracranial pressure. Patients' heart rate, blood pressure, oxygen levels, and other vital signs will be closely monitored throughout the procedure. The study also records any instances of nausea, vomiting, or shivering in the recovery phase. The results of this study will provide valuable insights into the effects of different anesthesia flow rates on intracranial pressure, potentially guiding future anesthesia practices.
