ABSTRACT
Background: Neonatal encephalopathy, following severe birth asphyxia or perinatal hypoxia is referred to as hypoxic ischemic encephalopathy (HIE). Cerebral ischemia occurs as a consequence of cerebral oedema and reduced cerebral perfusion due to myocardial dysfunction as a result of hypoxic cardiomyopathy. Sarnat stage I -100% recovery, HIE stage II - 80% normal and 20% mortality and HIE stage III - 50% mortality and 50% morbidity. Relatively few studies have been made on outcome in HIE affected preterm infants. The aims and objectives of this study was to find out the neurodevelopmental outcome in preterm infants with HIE.Methods: This study is an observational clinical study, undertaken in Kempegowda Institute of Medical sciences and research centre, Bangalore, India. Study was performed between November 2016 to September 2018. 31 preterm infants with HIE were included in the study. Regular follow-up was done at 3, 6, 9, 12.15, 18 months by using Trivandrum development screening chart (TDSC) to stage II HIE infants.Results: The incidence of abnormal neurological outcome was 12.9%. Out of 31 preterm babies, stage I were 24, stage II was 4 (100% morbidity) and stage III were 3 (100% mortality).Conclusions: In present study, stage II HIE had 100% morbidity and moderate disability, stage III 100% mortality. Thus at 3-5 months of age during follow-up, when authors identify developmental delay, it is an ideal time to start interventional therapy to improve long term outcome.
ABSTRACT
Objective To investigate the diagnostic value of cerebrospinal fluid protein in the assess-ment of neurological outcome in preterm infants with sepsis. Methods A total of 80 preterm infants with sepsis were enrolled in the department of neonatology of Shanghai Children's Hospital from June 2014 to June 2016. The lumbar puncture was completed within 24 hours after diagnosis of sepsis,and the results of ce-rebrospinal fluid protein were obtained. The prognosis of neurological development was assessed according to Gesell Developmental Quotient ( DQ) at 6 months of adjusted gestational age. DQ> 85 was used as an indi-cator of good prognosis group. DQ≤85 was assigned to the poor prognosis group. The differences in protein content of cerebrospinal fluid between these two groups were retrospectively analyzed. The receiver operating characteristic ( ROC) curve was used to evaluate the diagnostic value of cerebrospinal fluid in evaluating the prognosis of preterm infants with sepsis. Results Cerebrospinal fluid protein content of poor prognosis group was higher than those in good prognosis group[(2005. 56 ± 582. 85)mg/L vs. (1367. 92 ± 362. 29)mg/L, t= -6. 019,P<0. 01]. The area under the ROC curve was 0. 819(95％CI 0. 711 -0. 927,P<0. 05). The optimal threshold of cerebrospinal fluid protein was 1560 mg/L with specificity of 75. 5％ and sensitivity of 81. 5％. Conclusion Cerebrospinal fluid protein content has certain diagnostic value on the assessment of sepsis premature neurological prognosis.
