Abstract

Background: Hypoxic Ischemic Encephalopathy carries high case fatality rates ranging between 10-60%, with 25% of survivors have an adverse long-term neurodevelopment outcome. Despite the above, there is paucity of data regarding its magnitude and short term outcomes in a low resource setting like Uganda. Therefore we set out to determine the incidence and short term outcomes of Newborns with Hypoxic Ischemic Encephalopathy at St.Francis Hospital, Nsambya.

Methods: This was a Prospective Cohort study conducted between October 2015 and January 2016 at St. Francis Hospital, Nsambya, Kampala- Uganda. Term Newborn babies were enrolled. Umbilical cord arterial blood gas analysis was done for Newborns with low Apgar scores at 5 min. Clinical examination was done on all newborns within 48 h of life, for features of encephalopathy. Neonates with Hypoxic Ischemic Encephalopathy were followed up by a daily clinical examination and a short term outcome was recorded on day seven.

Results: The incidence of Hypoxic Ischemic Encephalopathy was 30.6 cases per 1000 live births. The majority, 10 (43.5%) had mild Hypoxic Ischemic Encephalopathy, followed by 8 (34.8%), 5 (21.7%) that had moderate and severe Hypoxic Ischemic Encephalopathy respectively. A total of (6) 26% died, and (15) 65.2% were discharged within 1 week. Lack of a nutritive suckling reflex (nasogastric feeding), poor Moro reflex, and requirement for respiratory support (oxygen therapy by nasal prongs) were the common complications by day seven.

Conclusions: The burden of Hypoxic Ischemic Encephalopathy is high with a case fatality rate of 26%. There is need to conduct a longitudinal study to determine the long term complications of HIE.
