Objective: to present our experience with the use of laryngeal mask (LM)during anesthesia for cardiac catherization in pediatric patients (PP). Methods: One hundred and 20 patients underwent a total of 127 cardiac catherization procedures. Their cases were analyzed retrospectively. The information was obtained from medical records, operative notes and cath lab reports from PP who underwent diagnostic and therapeutic procedures. Results: Only 88 procedures out of the 127 had complete information. There were 43 females (48%)and 45 males (52%). The patients' weight ranged between 2. 7 to 68 kgs and their ages between 12 hours to 14 years old. The procedures lasted from 45 minutes to 2. 45 hours. Sixty-six procedures were diagnostic, 9 were valvuloplasties, 4 septostomies, 1 pericardiocentesis, 4 angioplasties (2 of aortic coarctation and 2 of pulmonary artery branches), 2 coil closures of a leak and 2 ductus coil closures. Sevoflourane at high concentrations (8%)was used for induction. The LM was inserted when the patient reached anesthetic level and then this gas was cut back to keep the patient in a lighter plane, maintaining spontaneous ventilation and then it was discontinued all together. One patient (1.1%)presented severe laryngeal spasm that required endotraqueal intubation, the rest of the patients came out of the cath lab alert and with spontaneous ventilation and normal respiratory parameters. Conclusions: The utilization of LM for PP anesthesia is a safe method, is easy and it involves less airway invasion and it permits utilization of gases and adequate oxymetric control with low complication index.
