Methods Postoperative phrenitis was evaluated with the confusion assessment method for the intensive care unit in 1 835 patients underwent spine surgery between January 2007 and October 2009. All the patients with postoperative phrenitis were randomly divided into two groups: treatment group and control group. The patients in treatment group underwent intravenous injection with droperidol (5 mg). Results Three days after the operation, 136 patients were diagnosed with postoperative phrenitis. The pre-operative complications of hypertension and diabetes, hemorrhage amount (gt;600 mL) during the operation, operative time (gt;4 hours), hormone usage during the operation, postoperative electrolyte disturbances, hyoxemia and pain were the factors influencing the morbidity of postoperative phrenitis. The length of hospital stay was shorter in the treatment group than that in the control group (Plt;0.05). Conclusions Senility, pre-operative complications of hypertension and diabetes, hemorrhage amount (gt;600 mL) during the operation, operative time (gt;4 hours), hormone usage during the operation, postoperative electrolyte disturbances, hyoxemia and pain were the factors influencing the morbidity of postoperative phrenitis. Droperidol is effective on postoperative phrenitis.
