BACKGROUND: Apnoea of prematurity (AOP) frequently recurs in preterm infants. We have previously shown that a significant but variable proportion of AOP is induced by gastro-oesophageal reflux (GOR). AIM: The aim of this study is to evaluate the efficacy of sodium alginate in reducing the frequency of GOR-related AOP. SUBJECTS: Twenty-eight preterm infants with AOP were studied by a six-hour recording of combined multichannel intraluminal impedance and pH monitoring and polysomnography, including two three-hour postprandial periods: sodium alginate was given after one single meal named as drug-given (DG) meal, while the other as drug-free (DF). RESULTS: During 165h of registration, 715 apnoeas were recorded, 368 after-DG and 347 after-DF (p=.99); furthermore, 851 GOR episodes were detected, 315 after-DG and 536 after-DF (p=.001). No differences in the number of AOP were found between DG and DF. A significant reduction in the number of acid GORs and in acid exposure was found during DG, while the administration of sodium alginate didn't influence non-acid GOR indexes. The frequency of GOR-related apnoeas didn't differ between DG and DF. DISCUSSION: Sodium alginate doesn't reduce the total number of AOP nor GOR-related apnoeas. On the other hand, it reduces acid GOR features, while it had no effect on non-acid GOR indexes.
