Objective : To determine the incidence, causes, management and outcome of desaturation
occurring in the perioperative peroids (induction, maintence, emergence and recovery room) at Siriraj
Hospital from June 2001-December 2001.
Method : Perioperative incident reports were collected and analyzed. Patients were catergo-
rized as having desaturation if the Sp0
2
was below 90 per cent for more than 3 minutes. The inci-
dence, causes, management, and outcomes of these patients were examined in detail.
Results : 62 out of 16,716 cases (0.37%) experienced desaturation. Elective patients (0.41%)
experienced desaturation more frequently than emergency patients (0.14% ). The causes were airway
obstruction, hypoventilation, endotracheal tube problems, aspiration, atelectasis, and pulmonary
edema. These patients were treated with higher Fi0
2
,
airway management, and ventilatory support
which led to unplanned ICU admission. 4 patients developed cardiac arrest with successful resuscita-
tion although 2 patients had cerebral infarction.
Conclusion : Perioperative desaturation is an important sign of respiratory complications
that should be recognized and treated immediately to prevent mortality and serious morbidity.
