BackgroundHypoxic-ischemic encephalopathy (HIE) is a condition that may cause multiple organ dysfunction and has a high rate of mortality and morbidity. Therapeutic hypothermia is the only proven treatment that decreases the sequel and mortality rate of neonates that are born after 36 weeks of pregnancy and have moderate-severe HIE.MethodsOur study was a single-center, retrospective study that includes newborns (gestational age ≥ 36 weeks) who underwent therapeutic hypothermia due to hypoxic-ischemic encephalopathy between 2010 and 2020. We evaluated 125 patients who were diagnosed with moderate to severe HIE and received therapeutic hypothermia. Demographic and clinical data were obtained from electronic medical records and patient files. The patients were separated into two groups as exitus group (n = 39) and discharged group (n = 86). We aimed to evaluate factors affecting mortality.ResultsWe determined that the median resuscitation times were longer in the delivery room [retrospectively, 10th minutes (0-30) vs. 1 min (0-20), p < 0.05], the tenth min APGAR scores were lower [respectively, 4 (0-7) vs. 6 (3-10), p < 0.05], and the median pH value in the first blood gas taken was lower [respectively, 6.87 (6.4-7.14) vs. 6.90 (6.58-7.12), p < 0.05] in the exitus group. We also determined that multiple organ dysfunction is seen more often in the exitus group.DiscussionThis study demonstrated that the depth of acidosis in the blood gas, multiple organ dysfunction, and the existence of early-onset seizures are the signs of poor prognosis. Therefore, physicians need to be aware of such prognostic factors to follow these patients more closely in terms of possible complications and to inform their parents.
