[Effect of caffeine citrate on early pulmonary function in preterm infants with apnea].

Objective: To investigate the effect of caffeine citrate treatment on early pulmonary function in preterm infants with apnea.

Methods: Forty preterm infants with apnea were randomly divided into aminophylline treatment group (20 infants) and caffeine citrate treatment group (20 infants). When the preterm infants experienced apnea after birth, they were given aminophylline or caffeine citrate in addition to assisted ventilation with continuous positive airway pressure (NCPAP).
