“…Nevertheless, all these reports conclude that survival is never seen in babies of less than 23 weeks' gestation and is only to be expected in about 5% of all live births at 23 weeks. Other reports from Europe have found no evidence of long term survival in babies born before 24 weeks' gestation 2728293031. Only one previous study has documented death during delivery 23.…”

“…Only one previous study has documented death during delivery 23. Nine of these reports included information on disability in long term survivors, but only one was a population based study,12 and in only four was there no loss to follow up among babies of less than 28 weeks' gestation 16 20 27 30. The failure of surfactant to have any detectable impact on survival in babies of less than 26 weeks conflicts with the interpretation placed on several other studies that have used historic controls,323334 but is in keeping with the only randomised, multicentre, placebo controlled trials of surfactant specifically designed to study its efficacy in babies of less than 750 g at birth 35 36…”

“…[8][9][10][11][12] Very low birth weight babies often pose various social, medical and other problems which are out of proportion to their relatively small numbers. 3,[13][14][15][16] The authors consider it rather premature to discuss means of preventing ELBW deliveries in this report, but for now it is prudent to aim at improving facilities for care of ELBW babies in the hospital. In this respect the authors agree with the selective approach recently advocated by Jelly et al, 17 consisting of aggressively caring for ELBW babies likely to survive.…”

Babies of birth weight less than 1000 g (ELBW) often pose a heavy burden on available facilities in neonatal intensive care units (NICU) the world over. Reports from various countries show that survival rates among this category of babies still remain relatively low. [1][2][3][4] In a previous report from Afif General Hospital, the 28-day survival rate among ELBW babies was 30%, but within this category, there was no survival among the subset of birth weight less than 750 g. 5 Anecdotal evidence seems to suggest an increase in the proportion of these babies born in this hospital in recent times, and a cursory inspection appeared to show a higher incidence compared to data from an earlier audit by Al Faraidy et al., 6 pooled from other hospitals in Saudi Arabia. The authors, therefore, set out in this report to determine the circumstances related to the delivery of this group of babies in this hospital during the sixyear period from January 1992 to December 1997, paying particular attention to possible trends and other timerelated changes. Subjects and MethodsThe subjects consisted of mothers with newborn babies of birth weight 500 g and above, including stillbirths, during the six-year period. The focus of interest was the group of babies of birth weight less than 1000 g, who were selected as a subset. Data including birth weight, infant sex, month of delivery, outcome, maternal age, gravidity and parity were retrieved from the delivery records. For the comparative study, two groups of mothers were used-one consisting of mothers of singleton babies of birth weights ≥2500 g (normal birth weight), and the other of singleton babies of birth weights <1000 g (ELBW babies). Two mothers were selected from the former group-that of the baby born immediately before and the other immediately after each ELBW baby. Twins, macerated stillbirths and grossly abnormal fetuses were excluded from the comparative study because of the possibility of their disproportionate contribution to low birth weight.The birth weight distribution in the Afif General Hospital dataset was first compared with that published in 1993 by Al Faraidy et al., 6 using Poisson probability test. An expected number of ELBW births and a ratio of observed to expected ELBW births, with their corresponding 95% confidence intervals, were derived while noting particularly the magnitude of the departure of the observed number of ELBW births from the expected number. Statistical AnalysisData were analyzed using the Software Statistical Package PEPI Version 2 (Computer Programs for Epidemiologic Analysis).7 The annual delivery rates of ELBW babies were tested for possible trends using CoxStuart method. Monthly rates of delivery of ELBW babies over the combined 12 months of the study period were tested for patterns of variations by Hewitt's rank sum test for seasonal peak. Column statistic was carried out on the ages of all the mothers, deriving the median, first and third quartiles for age, and the interquartile range (IQR). Subsequently, two target ages were delinea...

“…A number of babies between 22 and 26 weeks gestation are born dead, but it is difficult to obtain accurate, geographically based data on this group. In a five year study (1980–1984) in Dundee 99 of 149 infants born between 20 and 28 weeks were stillborn (Walker & Patel 1987). Information about the proportion of liveborn to total births is useful when it comes to counselling a woman in preterm labour at or before 26 weeks gestation.…”
