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.

The centralisation of neonatal intensive care in recent years has improved mortality, particularly of extremely preterm infants, but similar improvements in morbidity, such as neurodevelopmental impairment, have not been seen. Integral to the success of centralisation are specialised neonatal transport teams who provide intensive care prior to and during retrieval of high‐risk neonates when in‐utero transfer has not been possible. Neonatal retrieval aims to stabilise the clinical condition and then transfer the neonate during a high‐risk period for patient. Transport introduces the hazards of noise and vibration; acceleration and deceleration forces; additional handling and temperature fluctuations. The transport team must stabilise the infant fully prior to transport as when on the move they are limited by space and movement to effectively attend to clinical deterioration. Inborn infants have better neurodevelopmental outcome compared with the outborn and aetiology of this seems to be multifactorial with the impact of transport itself during critical illness, remaining unclear. To improve the neurological outcomes for transported infants, it seems imperative to integrate the advancing intensive care neuromonitoring tools into the transport milieu. This review examines current inter‐hospital transport neuromonitoring and how new modalities might be applied to the neurocritical care delivered by specialist transport teams.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
