[The impact of early hypoxemia on the prognosis of patients undergone general anesthesia patients in intensive care unit].

Objective: To form the strategy of prevention of postoperative pulmonary complication, investigate the incidence of early hypoxemia after general anesthesia for surgery in intensive care unit (ICU), and assess its impact on the prognosis of patients.

Methods: Clinical data of patients who were directed transferred to ICU after general anesthesia for selective surgery during October 2011 to June 2012 were analyzed retrospectively. According to the oxygenation index (PaO2/FiO2) obtained in 1 hour after ICU admission, patients were divided into three groups, normal blood oxygen level (n=134, PaO2/FiO2>300 mm Hg, 1 mm Hg=0.
