ABSTRACT

Objective To compare the efficacy of postoperative noninvasive positive pressure ventilation ( NPPV ) plus standard medical therapy ( SMT) with SMT alone in patients with moderate to severe chronic obstructive pulmonary disease ( COPD )Methods Twenty-four patients, after upper abdominal or thoracic surgery, who suffered from COPD and moderate to severe respiratory insufficiency, were randomly allocated to receiving SMT alone (oxygen, aminophylline infusion, nebulized beta-2 agonists and anticholinergics, antibiotics administration and chest physiotherapy; control group ,n=12) or NPPV in addition to SMT(NPPV group ,n=12) NPPV was intermittently given with an air-cushioned face mask under the continuous positive airway pressure of 3 cmH 2O and FiO2 of 35%Results There were not significant differences in baselines between both groups 8 patients in control group ( 667%) and all patients in NPPV group recovered with initial therapy with statistically significant difference (P
