Insights
A new integrated care program effectively managed newborns with potential hypoxic-ischemic insult, controlling brain damage factors and enabling timely hypothermia treatment. This approach is crucial for reducing hypoxic-ischemic encephalopathy mortality and morbidity.
Area of Science:
- Neonatal care
- Neurology
- Public health
Background:
- Newborns with potential hypoxic-ischemic events require integrated care to mitigate brain damage.
- Early identification of candidates for hypothermia treatment is critical for improving outcomes.
Purpose of the Study:
- To implement and evaluate a prospective, population-based program for integrated care of newborns with perinatal hypoxic-ischemic insult.
- To systematize medical care within the first six hours of life for affected newborns.
Main Methods:
- A prospective, population-based program was applied across 12 hospitals for newborns >35 weeks gestational age with hypoxic-ischemic insult indicators.
- The program included protocols for detection, neurological surveillance, complication management, and transport procedures.
- Care was provided within the first 6 hours of life.
Main Results:
- From June 2011 to June 2013, 213 out of 32,325 newborns met criteria for potential hypoxic-ischemic insult (7.4/1000).
- 92% of eligible newborns received care according to program specifications.
- Moderate-to-severe hypoxic-ischemic encephalopathy was diagnosed in 33 cases (1/1,000), with 94% receiving timely hypothermia treatment.
Conclusions:
- The Integrated Care Program successfully provided comprehensive care for newborns with suspected perinatal hypoxic-ischemic insult.
- The program effectively controlled brain damage aggravators and facilitated early detection and treatment of moderate-to-severe hypoxic-ischemic encephalopathy.
- Population-based programs are essential for reducing mortality and morbidity associated with hypoxic-ischemic encephalopathy.
Introduction:
Newborns with perinatal indicators of a potential hypoxic-ischemic event require an integrated care in order to control the aggravating factors of brain damage, and the early identification of candidates for hypothermia treatment.
Patients And Methods:
The application of a prospective, populational program that organizes and systematizes medical care during the first 6 hours of life to all newborns over 35 weeks gestational age born with indicators of a perinatal hypoxic-ischemic insult. The program includes 12 hospitals (91,217 m(2)); two level i centers, five level ii centers, and five level iii hospitals. The program establishes four protocols: a) detection of the newborn with a potential hypoxic-ischemic insult, b) surveillance of the neurological repercussions and other organ involvement, c) control and treatment of complications, d) procedures and monitoring during transport.
Results:
From June 2011 to June 2013, 213 of 32325 newborns above 35 weeks gestational age met the criteria of a potential hypoxic-ischemic insult (7.4/1000), with 92% of them being cared for following the program specifications. Moderate-severe hypoxic-ischemic encephalopathy was diagnosed in 33 cases (1/1,000), and 31 out of the 33 received treatment with hypothermia (94%).
Conclusions:
The program for the Integrated Care of Newborns with Perinatal Hypoxic-Ischemic Insult has led to providing a comprehensive care to the newborns with a suspected perinatal hypoxic-ischemic insult. Aggravators of brain damage have been controlled, and cases of moderate-severe hypoxic-ischemic encephalopathy have been detected, allowing the start of hypothermia treatment within the first six hours of life. Populational programs are fundamental to reducing the mortality and morbidity of hypoxic-ischemic encephalopathy.
