Therapeutic hypothermia (TH) using servo-controlled cooling devices has proved to be a safe and effective method to reduce mortality and sequelae in neonates with hypoxic-ischemic encephalopathy (HIE). However, such cooling devices can be expensive and have limited availability in low-and middle-income countries. To evaluate the feasibility and effectiveness of low-cost cooling devices (ice packs) to reach and maintain the target temperature in newborns with moderate or severe HIE. Descriptive retrospective cross-sectional study, including newborns with gestational age ≥35 weeks, weight ≥1800 g, with diagnosis of moderate or severe HIE, submitted to whole body hypothermia using ice packs for 72 hr. Data was obtained from medical records and databases. The thermal curves of each patient, time spent at the target temperature and rewarming time were evaluated. Complications directly related to therapeutic hypothermia, evolution, and early outcomes before hospital discharge were analyzed. Seventy-one newborns met the criteria for TH, and 61 completed the entire cooling period and were included in the final analysis. The average time to reach the target temperature was 1.50 ± 1.3 hr. The mean temperature during the cooling period was 33.5 C (±0.62). 82.32% of the measurements were within the target temperature range (from 33 to 34 C). The following adverse events were observed during TH: pulmonary hypertension 11.3%, arrhythmia 4.2%, and coagulopathy 26.7%. Whole body hypothermia using low-cost devices proved to be an effective method in the absence of availability of servo-controlled devices, representing a plausible option in restricted resource settings.

Background Management of high-risk newborns should involve the use of standardized protocols and training, continuous and specialized brain monitoring with electroencephalography (EEG), amplitude integrated EEG, Near Infrared Spectroscopy, and neuroimaging. Brazil is a large country with disparities in health care assessment and some neonatal intensive care units (NICUs) are not well structured with trained personnel able to provide adequate neurocritical care. To reduce this existing gap, an advanced telemedicine model of neurocritical care called Protecting Brains and Saving Futures (PBSF) Guidelines was developed and implemented in a group of Brazilian NICUs. Methods A prospective, multicenter, and observational study will be conducted in all 20 Brazilian NICUs using the PBSF Guidelines as standard-of-care. All infants treated accordingly to the guidelines during Dec 2021 to Nov 2024 will be eligible. Ethical approval was obtained from participating centers. The primary objective is to describe adherence to the PBSF Guidelines and clinical outcomes, by center and over a 3-year period. Adherence will be measured by quantification of neuromonitoring, neuroimaging exams, sub-specialties consultation, and clinical case discussions and videoconference meetings. Clinical outcomes of interest are detection of seizures during hospitalization, use of anticonvulsants, inotropes, and fluid resuscitation, death before hospital discharge, length of hospital stay, and referral of patients to specialized follow-up. Discussion The study will provide evaluation of PBSF Guidelines adherence and its impact on clinical outcomes. Thus, data from this large prospective, multicenter, and observational study will help determine whether neonatal neurocritical care via telemedicine can be effective. Ultimately, it may offer the necessary framework for larger scale implementation and development of research projects using remote neuromonitoring.
