ABSTRACT

Study objective: The main objective of this study was to describe risk factors of newborns who present different types of apnea events in neonatal care units.
Methods: Our study was carried out at Neonatal Care Units of Tertiary level in Mexico City between August 2002 and August 2003. Infants were selected from among 223 infants if they presented any type of apnea event in sleep polysomnographic recordings.
Results: Nearly 25% of patients from a neonatal care unit presented apnea events. Infants with apnea showed lower values of age, weight, and cephalic perimeter at birth than infants without apnea, but did not show more neurologic risk factors. Central apnea was significantly more frequent in infants with preterm birth (birthweight ‹ 1,500 g), obstructive apnea was observed in infants with hyperbilirubinemia and gastroesophageal reflux, while mixed events were manifested in infants with sepsis, and hyperbilirubinemia. Sleep polysomnographic recordings detected that 36% of infants with apnea have no previous clinic suspicion of apnea.
Conclusions: Central events of apnea were found significantly more frequent in infants with preterm birth, obstructive events in newborns with hyperbilirubinemia and gastroesophagic reflux, while infants mixed apnea had more frequently hyperbilirubinemia and sepsis.
