6M.D. Asistant Professor, Recep Tayyip Erdogan Universitesi Faculty of Medicine, Department General Surgery, Rize/TURKEY Purpose: To assess the potential impact of sevoflurane anesthesia on intraocular pressure (IOP) in patients undergoing laparoscopic cholecystectomy.
Materials and Methods: The study included 34 elderly patients 60 and over who were to undergo a laparoscopic cholecystectomy for cholelithiazis. Mean arterial blood pressures (MBPs) and mean IOPs of both eyes were measured on five occasions: before anaesthetic induction (MBP1, IOP1), after anaesthetic induction and during mechanical ventilation (MBP2, IOP2), after pneumoperitoneum (MBP3, IOP3), after evacuation of pneumoperitoneum (MBP4, IOP4), and 1 hour after tracheal extubation (MBP5, IOP5).
Results: The mean age of patients was 63.24±6.61. MBPs were 114.51±22.05 (MBP1), 106.16±19.46 (MBP2), 101.07±16.32 (MBP3), 98.88±11.95 (MBP4), and 110.88±10.69 (MBP5). IOPs were 18.75±2.49 (IOP1), 16.47±3.2 (IOP 2), 17.09±3.52 (IOP3), 16.5±3.72 (IOP4), and 18.85±2.3 (IOP5). The effect of pneumoperitoneum on MBP and IOP was found to be statistically insignificant (p=0.135 and p=0.094, respectively).
Conclusion: IOP changes were in normal limits in elderly patients during laparoscopic cholecystectomy operation with sevofluran anesthesia.
