Dr. Sriram Ramgopal, a Pediatric Emergency Medicine specialist, discusses diagnosing hypothermic infants for sepsis, challenges in differential diagnosis, and the need for infectious workups. The podcast explores empiric antibiotic therapy, management strategies, and the importance of collaboration in neonatal hypothermia research.
Recognizing hypothermia in infants requires attention to vital signs like bradycardia and perfusion.
Distinguishing between well-appearing and unwell infants involves vital sign abnormalities and physical exam findings.
Managing hypothermic infants includes systematic history-taking, tests for infections, and consideration of empiric antibiotic therapy.

Identifying Hypothermia in Infants
Recognizing hypothermia in infants, especially in clinical settings, requires paying attention to vital signs like bradycardia, irregular breathing, and degree of perfusion. Concerns for lethargy, apnea, and feeding difficulties, alongside physical exam findings such as sunken fontanelle or dehydration indicators, contribute to assessing the severity.
Differential Diagnosis for Hypothermic Infants
In differentiating between well-appearing and unwell infants with hypothermia, vital sign abnormalities like bradycardia and respiratory irregularities may indicate a heightened risk. An abnormal physical examination, where the baby appears lethargic or manifests poor perfusion, can further raise concern for a serious bacterial infection. Look for indicators such as abnormal weight gain or hyperbilirubinemia to aid in diagnosis.
Management and Diagnostic Approach
Managing hypothermic infants involves a systematic approach, encompassing history-taking, physical examination, and ancillary tests. Testing for serious bacterial infections, HSV, blood sugar evaluation, and bilirubin levels can provide valuable insights. Empiric antibiotic therapy may be considered based on clinical suspicion, especially when facing uncertainty in laboratory results.
Prevalence and Research Gaps in Hypothermic Infants
Research on hypothermia in infants, while limited and mainly based in Children's Hospitals, suggests a prevalence lower than fever presentations. Disparities in healthcare delivery related to race, ethnicity, or socioeconomic status in hypothermic infants remain largely unexplored. Further studies are needed to address gaps in knowledge and standardized management protocols.
Expert Insights and Future Directions
Expert insights highlight the complex nature of hypothermia assessment in infants and the need for individualized care. Emphasis on conservative management in uncertain cases, thorough examination of babies for signs of illness, and interdisciplinary collaboration are key to optimizing outcomes. Continued research efforts, such as multi-center studies, aim to refine diagnostic and treatment strategies for hypothermic infants.
All is not frost, we’re back to talk through the Hypothermic Infant with Dr. Sriram Ramgopal (Pediatric Emergency Medicine, Lurie Children’s Hospital). How do we know if the baby is septic or is just two blankets short of euthermia? Dr. Ramgopal walks us through the latest research, a differential diagnosis, who needs an infectious workup, and how much more we have to learn!
