CASANUEVA, C. Paulina  and  CIFUENTES, R. Javier. Hospital Admissions due to cyanosis episodes in newborns with gestational age of 34 weeks or more. Rev. chil. pediatr. [online]. 2015, vol.86, n.4, pp.244-250. ISSN 0370-4106.

Objectives: A retrospective study was performed between January 2007 and December 2012 to assess the admission rates of newborns due to episodes of cyanosis Patients and method: Retrospective study that included all the newborns hospitalized with episodes of cyanosis between January 2007 and December 2012. In them were employed two study protocols that considered first and second line tests, the latter in view of recurrence of events. The first line protocol considered general biochemical tests, chest x-ray and echocardiography in selected cases, while the second line protocol included electroencephalogram, electrocardiogram, nuclear magnetic resonance of the brain, expanded metabolic screening, pyruvic acid, lactic acid, and in case of seizures, cytochemical, and culture of cerebrospinal fluid (CSF) and PCR (polymerase chain reaction) for herpes. Results: A total of 98 (2.8%) out of 3,454 newborns were admitted due to episodes of cyanosis. Gestational age: 37.8 + 1.4 weeks, birth weight: 3,145 + 477 g. Maternal age: 32 + 4.8 years. Disease was present in 19.4% of mothers; gestational diabetes (8.1%), pregnancy induced hypertension (5.1%), intrahepatic cholestasis (3.1%), and intrauterine growth retardation (3.1%). Gender: 48.8% male, 51.2% female (NS). Birth: caesarean section, 68.4%, and vaginal delivery, 31.6%. Age on admission 1.9 + 1.4 days. Hospital stay: 4.2 + 4.2 days. First line tests were performed in 100% of patients with 39.8% fulfilling the criteria for second line study. A condition was detected in 21.4%, with convulsive syndrome was the most frequent (33%). Newborns with an identified condition had 3.8 + 2.7episodes versus 1.5 + 2,4 in those without diagnosis (NS). A home oxygen monitor was given to 15.4%. There were no re-admissions. Conclusions: Most newborns admitted due to cyanosis are discharged with a condition of unknown origin. In this study, convulsive syndrome was the most frequent cause.
