Direct laryngoscopy on general anesthesia in Pediatrics represents a challenge for anesthesiologists and otorrhinolaryngologists, because they have to share the small space of the airways. A number of 100 patients with 5 to 6 years of age were studied for latyngeal interventions with general anesthesia, at Pepe Portilla Provincial Children's Hospital in Pinar del Río, Cuba. Patients were divided into two groups of 50, the first group with high-frequency ventilation (VAF), of 2 Hz (FR = 120 breaths/minute) with Servo Ventilator 900 D, and the second group was ventilated by Sander's method (modified by Rivas). VAP turned out a simple and safe method, by determining volume and the respiratory rate corresponding to each patient, which in turn made it easier for the surgeon. The complications were minimal, showing advantages derived from the low volume used, achieving an effective exchange of CO2 and O2 with lower peak pressures, minimal variations in pressures and volumes of ventilation and, consequently, minimal impact on the cardiovascular performance.
