Post-Resuscitation Care for Newborns

Introduction to Post-Resuscitation Care

The American Academy of Pediatrics recommends that newborns who have required resuscitation should be maintained in an environment that allows for close surveillance and anticipatory care, as they are at risk of deterioration even after normalization of vital signs 1, 2, 3

The American Heart Association recommends continuous heart rate monitoring with a target of >100/min, using ECG or repeated precordial auscultation 4
The American Academy of Pediatrics recommends maintaining preductal oxygen saturation ≥95% with a preductal-postductal difference <5% 4
The American Academy of Pediatrics also recommends assessing peripheral perfusion with a capillary refill time ≤2 seconds and normal peripheral pulses without central-peripheral differential 4
The American Academy of Pediatrics suggests maintaining diuresis >1 mL/kg/h as an indicator of adequate renal perfusion 4
The American Academy of Pediatrics recommends maintaining body temperature between 36.5-37.5°C and avoiding hyperthermia >38°C 6

The American Heart Association recommends considering intravenous glucose administration as soon as possible after resuscitation to avoid hypoglycemia 1, 2, 3
Newborns with low blood glucose are at increased risk of brain injury after hypoxic-ischemic insult 1, 2
Although no specific glycemic target has been identified, the primary goal is to avoid hypoglycemia 1, 2, 3

The American Academy of Pediatrics recommends considering therapeutic hypothermia for term or near-term newborns with moderate to severe hypoxic-ischemic encephalopathy 4, 7
This intervention improves mortality and long-term neurological morbidity 4, 7
The protocol and follow-up should be coordinated by a regional perinatal system 4, 7
Inclusion criteria: ≥36 weeks of gestation with signs of encephalopathy within the first 6 hours 4, 5

The American Academy of Pediatrics recommends regulating oxygen supplementation after resuscitation using pulse oximetry 4, 7
Avoiding prolonged hyperoxia, which can be deleterious 4, 7
Maintaining preductal saturations according to normal curves for healthy newborns (60% at 1 minute, progressing to 90% at 10 minutes) 6

In cases of suspected blood loss (pale skin, poor perfusion, weak pulse) without adequate response to other measures, administer 10 mL/kg of isotonic crystalloid solution or blood 1, 2, 3
May require repetition of the dose 1, 2
In preterm infants, avoid rapid infusions of large volumes (risk of intraventricular hemorrhage) 1, 2, 3

Once effective ventilation and/or circulation are established, transfer to a neonatal intensive care unit for continuous surveillance 1, 2, 3
Maintain a thermally neutral environment with a radiant heat source 8, 6

Do not interrupt surveillance early, as deterioration can occur after initial normalization of vital signs 1, 2, 3
Do not neglect thermoregulation, as hypothermia increases oxygen consumption and worsens acidosis 9, 8
Do not administer naloxone in the delivery room for respiratory depression - restore heart rate and oxygenation through ventilation first 1, 2, 3
Avoid hypoglycemia: start glucose IV quickly, do not wait for clinical signs 1, 2

Post-resuscitation surveillance should be dynamic with frequent re-evaluation 1, 2
Capillary glucose in the first hour and then according to protocol 1, 2
Continuous neurological evaluation to identify hypoxic-ischemic encephalopathy 4, 5
