laryngeal mask airway versus endotracheal tube for intraocular surgery

ABSTRACT

The use of the laryngeal mask was compared with tracheal intubation in 20 patients who underwent intraocular ophthalmic surgery and received standardized anesthesia. The changes in intraocular pressure was significantly less in the LMA group at all time points after airway instrumentation. The change in mean arterial pressure was significant between the two groups but the heart rate changes were insignificant. The mean rate pressure product was significantly smaller in LMA group compared with ETT group after both insertion and removal. At the end of the procedure, a significantly higher percentage of patients tracheal tube coughed, reacted to head movement and suffered breath holding as they also complained of postoperative sore throat more than patients with LMA
