ABSTRACT
To find out the incidence of self-extubation in intensive care, to evaluate the factors responsible for it and to identify the predictors of need for re-intubation, a retrospective analysis was conducted among 350 patients who were admitted to the intensive care unit over a two-year period and required ventilatory therapy for more than 48 hours. In all patients who self-extubated, the demographic data, ventilatory parameters before self-extubation (mode of ventilation, inspired oxygen concentration, positive end-expiratory pressure), partial pressure of oxygen in arterial blood and inspired oxygen fraction ration (PaO2/FiO2), and the event of re-intubation were noted. These values were compared among patients who were re-intubated and those who were not. Twelve patients out of 350 self-extubated. Of these 12 patients, 7 required re-intubation while 5 did not. Of these 7 patients, 3 died within 48 hours of the episode of self-extubation and one patient's death was directly attributable to self-extubation. Of the remaining 4 patients, 3 died within a span of 7 days. Re-intubation after self-extubation should not be considered mandatory. Patients who required re-intubation had lower PaO2/FiO2 than patients who did not.
