Continuous positive airway pressure (CPAP) administered at intervals with a mask and incentive spirometry (IS) were compared with a regimen of coughing and deep breathing (CDB) to determine which promoted the most rapid recovery of pulmonary function after upper abdominal operations in 65 adults. Postoperatively, FRC of patients in all groups was similar relative to preoperative values. However, mean FRC of patients who received CPAP increased more rapidly than did mean FRC of those receiving CDB when compared to the values obtained following operation (p less than 0.05). ⋯ The low incidence of pneumonia regardless of the type of therapy may be attributable to vigorous, vigilant respiratory care in a population at high risk for developing pneumonia. Frequency and supervision of respiratory therapy may be more important than the type of therapy delivered after upper abdominal operations. Mask CPAP offers advantages because it requires no effort from the patient, and therapy is not painful.

Asthma in children has many special features which deserve consideration. This disease is probably underdiagnosed and is often undertreated. Vague, persistent respiratory symptoms, especially chronic cough, may often be due to asthma. ⋯ Nevertheless, many children with moderate or severe asthma will continue to be troubled by intermittent or chronic airway obstruction into adulthood, and they require long-term, anticipatory treatment programs. Comprehensive care will optimize the quality of life for the affected children and their families, and it will minimize the discomfort and restrictions to which some of them have been subjected unnecessarily. Asthma in childhood, especially when not well controlled, may constitute a risk factor for the development of chronic obstructive pulmonary disease in adulthood; however, this is as yet only suspected and not proved.

We reviewed 94 cases of prehospital ventricular fibrillation (VF) to determine aspects of field response that predicted outcome. Only one of 37 patients (3 percent) failing to achieve rhythms other than VF or asystole after the first two defibrillations survived to hospital discharge compared to nine of 57 (16 percent) achieving organized rhythms by this point (p less than 0.05). ⋯ Thus, for prehospital VF, the best field response identifies potential survivors prior to hospital arrival. In addition, the frequent occurrence and potentially favorable outcome of an initially pulseless rhythm necessitates reevaluation of current therapy.
