The aim of this study was to determine the prevalence of ICH in VLBW and the distribution according to the intensity. The influence of birth weight, gestational age, asphyxia and time of mechanical ventilation in the prevalence, as well as the presence of apnea, hydrocephalus, periventricular leukomalacia and length of hospital stay among the VLBW were evaluated. 101 VLBW admitted from Jan. to Dec. 1995 were studied. Diagnosis of ICH was by ultra sound during the first week of life. Statistical analysis was by chi-square and t-test, with a significance of 0.05.
The prevalence of ICH was 29.8% (20/67), 70% were classified as Grade I, 0% as Grade II, 20% as Grade III and 10% as Grade IV; 34 VLBW were excluded(death within 48 hours after birth or failure in obtaining cranial ultra sound). The risk factors and the evolution is shown below.Table
The prevalence of ICH among the VLBW studied was 29.8%, being more frequent the Grade I. Birth weight and gestational age were the most important risk factors. Infants with ICH had higher prevalence of apnea, hydrocephalus, periventricular leukomalacia, and length of hospital stay.
