Abstract

Hypoxic ischemic encephalopathy (HIE) is an important cause of permanent injury of central nervous system leading to neonatal death, cerebral palsy and developmental delay. Whole-body cooling therapy is the only effective treatment for HIE today. Subcutaneous fat necrosis during cooling period is rarely seen. A female newborn was born to 33-year-old gravida three parity two mother at 39 weeks of gestation by an emergent cesarean section due to fetal distress. The pregnancy course was complicated with gestational diabetes mellitus, mother received insulin therapy during the last trimester. On admission, she had abnormal neurological findings including hypotonia and absent neonatal reflexes. The patient was treated with postnatal hypothermia in the sixth hour of the method of whole body cooling. Forty-eight hours of treatment, subcutaneous fat necrosis was diagnosed and on the follow-up, the patient developed hypercalcemia and treated with pamidronate. Postnatal twenty-fifth day, patient was discharged with normal physical and neurological examination. Subcutaneous fat necrosis is a rare condition that can be seen during hypothermia period. Close monitoring of these patients because of hypercalcemia risk is important during follow-up.

Asfiktik bir yenidoğanda hipotermi tedavisi sonrasında gelişen subkutan yağ nekrozu olgusu

Abstract

Hipoksik iskemik ensefalopati (HİE), neonatal ölüm, serebral palsi ve ileri dönemde gelişimsel gerilikle sonuçlanabilen merkezi sinir sisteminin kalıcı hasarının önemli bir sebebidir. Tüm vücut soğutma tedavisi HİE'de günümüzdeki tek etkin tedavi yöntemidir. Tüm vücut soğutmaya bağlı subkutan yağ nekrozu gelişimi nadir görülen bir yan etkidir. Otuz üç yaşındaki annenin 3. gebeliğinden 2. yaşayan olarak sezaryen ile 3500 gram olarak doğan kız bebek postnatal 4. saatinde solunum sıkıntısı, hipotonisite ve konvülsiyon nedeni ile yenidoğan yoğun bakım ünitesine (YYBÜ) kabul edildi. Öyküden, annenin gestasyonel diyabet nedeni ile gebelikte son trimesterde insülin tedavisi aldığı öğrenildi. YYBÜ'ne kabulde, hasta entübe, genel durumu kötü ve hipotonikti. Hastaya postnatal 6. saatinde tüm vücut soğutma yöntemiyle hipotermi tedavisi başlandı. Tedavinin 48. saatinde subkutan yağ nekrozu ile uyumlu lezyonları gelişen hastanın izlemde hiperkalsemisi gelişti ve pamidronat tedavisinden fayda gördü. Hasta genel durumu iyi, lezyonları iyileşmiş ve nörolojik muayenesi normal olarak postnatal 25. günde taburcu edildi. Hipotermi tedavisinin komplikasyonları arasında subkutan yağ nekrozu nadir görülen bir durumdur. Subkutan yağ nekrozu genellikle kendiliğinden iyileşen bir patoloji olmakla birlikte hiperkalsemi riski nedeniyle hastaların yakından izlenmesi önemlidir.
