We know very little about the advantages of the use of the laryngeal mask over the endotracheal tube, in the aerial route handling. This is a comparative and descriptive study, and it was carried out on 40 operated patients under balanced general anesthesia. We used laryngeal mask in one first group of 20 patients and endotracheal tube in a second group of 20 remaining patients as a handling of the aerial route. The aim of this work is to compare the haemodynamic changes that produce the use of the laryngeal mask and endotracheal tube after intubation. In the first group, in most of the patients, the values of arterial pressure, cardiac frequeney and oxygen saturation remain the same after placing the laryngeal mask. In the second group it seems to increase the blood pressure and cardiac frequency after do the intubation. Oxygen saturation remains without changes. Therefore we conclude that the laryngeal mask provides more haemodynaic stability. The surgical time with laryngeal mask was 15 minutes to 2 hours and 40 minutes. There were not transoperatory complications in any of both groups, but we observed that with endotracheal tube in the postoperatory the patients presented, sore throat, dysphony, nausea and vomits. However, with laryngeal mask only nausea was present.
