AbstractEighty under-five children admitted in the pediatric ward with acute respiratory distress requiring oxygen inhalation were prospectively studied. Oxygen was administered to all the children by head box, face mask, nasopharyngeal catheter, and twin-holed prenasal catheter in a predetermined sequence. Oxygen was delivered at a flow rate of 4 l/min in the head box and by face mask and at a rate of 1 l/min for nasopharyngeal catheter and twin-holed prenasal catheter. There was a significant rise in paO2 and SaO2 values with all the oxygen delivery methods. The number of children who achieved paO2 of > 90 mmHg with oxygen delivered by head box was 53 (69 per cent), with face mask 37 (57 per cent), with nasopharyngeal catheter 13 (26 per cent), and with twin-holed prenasal catheter 18 (25 per cent). In view of high acceptability of twin-holed prenasal catheter, a further pilot study involving 10 children was carried out to compare the efficacy of head box and twin-holed prenasal catheter at an identical oxygen flow rate of 4 l/min. The number of children achieving paO2 of > 90 mmHg were comparable, i.e. seven (70 per cent) and eight (80 per cent) when the oxygen was delivered by head box and twin-holed prenasal catheter, respectively. It is concluded that both head box and twin-holed prenasal catheter are equally effective, acceptable and safe methods for administration of oxygen to children with acute respiratory disorders. In view of the cost-effectiveness, and easy availability and affordability of twin-holed prenasal catheter, it should be popularized in the small hospitals in the community, while head box should be reserved for use in the referral hospitals.
