Clinical Efficacy of Subhypothermia in the Treatment of Neonatal Hypoxic-Ischemic Encephalopathy Combined with Myocardial Damage

Objective. To investigate the efficacy of subhypothermia in the treatment of neonatal hypoxic-ischemic encephalopathy (HIE) combined with myocardial damage. Methods. 136 children with HIE and myocardial damage admitted to our hospital from October 2019 to October 2021 were included in the study and were divided into study group and control group of 68 cases each according to the random number table method. The control group was given conventional treatment, and the study group was treated with subhypothermia therapy on top of the control group. Comparing the effects of treatment between the two groups. The serum levels of S-100β protein, Tau protein, neuron-specific enolase (NSE), creatine kinase (CK), creatine kinase isoenzyme MB (CK-MB), lactate dehydrogenase (LDH), alpha-hydroxybutyrate dehydrogenase (ɑ-HBDH), myoglobin (Myo), cardiac trophic factor-1 (CT-1), cardiac troponin I (cTnI), superoxide dismutase (SOD), reactive oxygen species (ROS), glutathione peroxidase (GSH-Px), interleukin-1β (IL-1β), interleukin-8 (IL-8), and tumor necrosis factor-ɑ (TNF-ɑ) were measured in both groups before and after treatment, respectively. Results. The total effective rate was higher in the study group (88.24%) than in the control group (72.06%) (P
