In patients undergoing RALRP, the increase of 12.5% in ONSD during CO2 pneumoperitoneum with steep Trendelenburg positioning was observed and thus the increase of ICP corresponding to this change of ONSD could be predicted. In 15% of the enrolled patients, ONSD increased by values equivalent to an ICP above 20 mm Hg without a deterioration of rSO2 or any neurologic complications.

Our results showed that the i-gel had easier insertion and better sealing function, and the air-Q SP provided improved fiberoptic views in children requiring general anesthesia.

SummaryWe performed a randomised comparison of the i-gel TM and the Laryngeal Mask Airway (LMA) Classic TM in children aged less than a year who were undergoing general anaesthesia for elective surgery. Fifty-four infants were randomly allocated to either the i-gel or the LMA Classic. We measured performance characteristics, fibreoptic views through the device and complications. Success rate at first insertion attempt was 100% (27/27) in the i-gel group compared with 88% (23/26) in the LMA Classic group. Insertion of the device was considered easy in 26/27 (96%) patients in the i-gel group compared with 18/26 (69%) patients in the LMA Classic group (p = 0.009). There were no differences between the groups in insertion times, fibreoptic views through the device, airway leak pressures or complications. We conclude that the i-gel was considered easier to insert than the LMA Classic in infants.
