Optic Nerve Sheath Diameter Changes with Changing Intra-abdominal Pressure and End-Tidal CO2 in Laparoscopic Surgery: A Prospective, Observational Study
Author(s): Anjali Kumari* and Syed Moeid Ahmed
Introduction: Measurement of ONSD by ultrasonography is a surrogate measure of ICP in laparoscopic surgeries. This study aimed to evaluate the change in ONSD with changes in IAP and EtCO2 in patients undergoing laparoscopic cholecystectomy.
Methods: After approval from IEC and BOS, 60 adult patients undergoing elective surgery were selected for the study. Optic nerve aligned directly opposite the 6 MHz-13 MHz linear probe of USG machine of Hitachi Aloka F31 and ONSD measured 3 mm behind the globe perpendicular to axis of the scanning plane at T0, T1, T2, T3 i.e. after intubation, at IAP of 10 mm Hg, 15 mm Hg and after desufflation. Further, the changes in ONSD corresponding to changes in IAP were measured after standardizing EtCO2 to normal level (35 mm Hg-40 mm Hg).
