Prevalence of Pulmonary Hypertension During Therapeutic Hypothermia for Hypoxic Ischemic Encephalopathy and Evaluation of Short-Term Outcomes. Ther Hypothermia Temp Manag. 2024 Aug 12.2153-793310.1089/ther.2024.002339133665http://hdl.handle.net/20.500.14200/5729Infants with perinatal asphyxia and moderate-to-severe hypoxic ischemic encephalopathy (HIE) are currently treated with therapeutic hypothermia (TH) as part of a brain protective strategy. However, perinatal asphyxia is a risk factor for development of persistent pulmonary hypertension (PPHN). As such, the aim of this study was to quantify the risk of PPHN in infants undergoing TH and assess short-term outcomes in infants developing PPHN. All N = 59 infants undergoing TH for moderate-to-severe HIE over a period of 3 years (January 2020-December 2022) at a single center were included. PPHN was diagnosed in N = 10 (17%), with this deemed to have been exacerbated by TH in n = 6 (10%). Only 50% (5/10) with PPHN required inhaled nitric oxide, and none of the infants received extracorporeal membrane oxygenation. PPHN was not found to be significantly associated with short-term outcomes, including the extent of HIE on brain magnetic resonance imagings, in-hospital mortality or requirement for nasogastric feeding at discharge. In conclusion, TH appears to be a safe and effective treatment for moderate-to-severe HIE with or without PPHN.enIntensive carePrevalence of pulmonary hypertension during therapeutic hypothermia for hypoxic ischemic encephalopathy and evaluation of short-term outcomes.ArticleTherapeutic hypothermia and temperature management
