Abstract
Background: Neonatal hypothermia is common around the world; however, profound hypothermia is a very rare-but life-threatening-event.
Clinical Findings: This was a very rare case involving a 15-day old preterm infant diagnosed with profound hypothermia (rectal temperature, 27[degrees]C) concomitant with severe coagulation dysfunction and leukopenia on admission.
Primary Diagnosis: Profound hypothermia together with severe coagulopathy, leukopenia, late-onset sepsis, and pneumonia.
Interventions: The patient was rewarmed slowly, with a rectal temperature rising at a rate of 0.5[degrees]C/h < R < 1[degrees]C/h. Vital signs were closely monitored. Coagulation factors were supplemented by intravenous infusion of fresh frozen plasma. Supportive treatment with intravenous infusion of immunoglobulin was provided, and antibiotics were used empirically. Nil per os and intravenous rehydration were also implemented.
Outcomes: The condition of the preterm infant gradually improved and was successfully discharged.
Practice Recommendations: Profound hypothermia is very rare in preterm infants. However, once it occurs, it may be concomitant with severe coagulopathy and leukopenia. Successful management involves slow rewarming, prompt supplementation of coagulation factors, empirical antibiotics, and supportive treatment.
