Abstract

Aim: The laryngeal mask (LMA) has been used for years to provide a safe and effective airway. Nowadays, it is also preferred in gynecological laparoscopic operations. In our study, we aimed to evaluate the effects of Baska Mask LMA (LMA-B), LMA Supreme (LMA-S) and ETT (endotracheal tube) applications on intracranial pressure in laparoscopic gynecological operations by measuring optic nerve sheath diameter (ONSD).

 Methods:  Patients between the ages of 18-65 in ASA I-II-III physical status who were going to undergo laparoscopic gynecological operation were included in the study. The patients were divided into three groups by randomisation prospective as ETT, LMA-B and LMA-S. ONCD measurements were measured before general anesthesia (T0), 1 minute after induction (T1), 1 minute after intubation (T2), 3 minutes after intubation (T3), 10 minutes after the pneumoperitoneum and trendelenburg position (T4), and 30 minutes after the pneumoperitoneum and trendelenburg position (T5) and before extubation (T6).

Results: 60 patients were included in the study. No statistical difference was found between the groups in terms of demographic characteristics and clinical data (all p>0.05). The change in ONSD within three different groups showed an increase in the measurements at the 10th and 30th minutes after the pneumoperitoneum and trendelenburg position; ETT (4.84±0.23 mm), LMA-S (4.83±0.28mm), and this increase was found to be the lowest in LMA-B (4.64±0.26 mm) application (p=0.61).

Conclusion: we think that Baska Mask LMA can be preferred more than ETT and other LMA applications according to the indication and IBP follow-up can be done reliably with ONSD measurements.
