ABSTRACT

Objective: To describe the experience with invasive me-chanical ventilation (MV) in the Intensive Care Unit (ICU) of the “Hospital de Especialidades Centro Médico Nacional “La Raza” (HECMNR). Patients and methods: We carried out a retrospective, observational, descriptive and transversal study from 1st July 2000 to 1st July 2001. Patients older than 18 years who required MV more than 24 h were included. We used a ventilation-monitoring format as the primary source of information. We registered gender, age, indication of MV, ventilatory modes, tidal volume (Vt), maximum pressure (Pmax), pressure support (PS), positive end-espiratory pressure (PEEP), days of MV, time and ventilatory weaning technique. Results: From the total admitted patients, 20.70% received MV, of these 56.2% were women and the mean age of all patients were 47.96 ± 18.72 years. The main indications were acute respiratory failure (31.11%), immediate post surgical period (40%) and neurological illness (23.52%). The ventilatory mode most employed was assisted/controlled (A/C). The Vt was of 7.91 ± 1.19 mL/kg, Pmax of 32.91 ± 8.20 cmH2O, PS of 12.70 ± 3.12 cmH2O and PEEP of 7.67 ± 3.70 cmH2O. The length of MV was, 7.94 ± 7.72 days. The main weaning technique of MV was synchronic intermittent mechanical ventilation (SIMV) ± PS and length of weaning was 2.46 ± 2.83 days. Conclusion: Our experience with MV coincides with that reported in multicenter international studies carried out in Europe, United States and Latin America.
