Outcome of very low birthweight neonates in a developing country: experience from a large Malaysian maternity hospital.

Between January 1989 to April 1990 (16 months), a prospective observational study was carried out on 329 consecutive very low birthweight (VLBW) less than or equal to 1500 grams) Malaysian neonates born in the Maternity Hospital, Kuala Lumpur before their first discharge from the hospital. The objectives of the study were to determine the common causes of early morbidity and mortality of this group of Malaysian neonates. The study shows that the incidence of Malaysian VLBW neonates was 9.9 per 1000 livebirths (95% confidence intervals 9.0 to 10.8). The mean duration of stay in the hospital was 19.3 days (SD = 21.4). One hundred and ninety-six (59.6 percent) of the VLBW neonates died. They accounted for 60 percent (196/334) of all neonatal deaths in the hospital during the study period. Mortality was significantly higher in neonates of birthweight less than 1000 grams (p less than 0.01) and of gestation of less than 33 weeks (p less than 0.001). The three most common clinical problems were respiratory distress syndrome (RDS) (72.6 percent), septicemia (28.0 percent) and intraventricular haemorrhage (IVH) (21.9 percent). Death occurred in 71.1 percent of the septicemic patients. The most common causative organisms of septicemia were multiresistant klebsiella (52.3 percent) and multiresistant acinetobacter (14.7 percent). RDS (33.2 percent), septicemia (29.6%) and IVH (17.9 percent) were the three most common causes of death. Improvement in the nursing staff situation and basic neonatal care facilities in this hospital and prevention of premature delivery could help to decrease morbidity and mortality in this group of neonates.
