Summary. There is a marked paucity of data on the prevalence, management, and outcome of
respiratory distress syndrome (RDS) among newborn infants born in developing countries. We
reviewed the clinical profile, presentation, mode of therapy, and immediate and 12-month out-
comes in 200 consecutive infants with documented RDS admitted to the Neonatal Intensive
Care Unit at Aga Khan University Hospital, Karachi.
One hundred fifty-six (79%) of these infants required assisted ventilation. Infants requiring
ventilatory assistance had higher rates of maternal antenatal complications, were more fre-
quently asphyxiated at birth, and were hypothermic on admission. The overall mortality was
39%, and a further 3 infants died in early infancy after discharge. The mean duration of hospi-
talization for ventilated survivors (n = 122) was 24.6 ± 21.1 days, with an average cost of therapy
per survivor of Rs 50,067 (US $1,391). While our experience from Karachi indicates that it is
possible to provide successful respiratory support at comparatively low cost to newborn infants
weighing >1,000 g with severe RDS, there is considerable room for improvement in outcome
with the use of preventive measures such as antenatal steroids, appropriate intrapartal care, and
attention to early stabilization after birth. Pediatr Pulmonol. 1999; 27:305–311.

INTRODUCTION
Respiratory distress syndrome (RDS) is a leading
cause of mortality among newborn infants in the Western
world, with an estimated incidence of 1% of all live
births.

Prior to the introduction of surfactant replace-
ment therapy, the mortality associated with the disorder
ranged from 14–30%.

The introduction of surfactant
replacement therapy in developed countries has resulted
in a significant reduction in morbidity and mortality in
this high-risk group.

However, the situation in the developing world is very
different. Although early neonatal deaths have been
clearly identified as a major component of infant mor-
tality,

the contribution of RDS to neonatal morbidity in
the developing world is unknown. This is mainly due to
inadequate epidemiological information as to the preva-
lence and severity of this disorder, as most very low birth
weight (VLBW) infants die soon after birth, and causes
of death other than prematurity are poorly recognized. In
some series from developing countries where informa-
tion is available on the early course of VLBW infants,
RDS has been documented in 2–3% of all births,

with
extremely high mortality rates.

While therapeutic
strategies for managing RDS in most developing coun-
tries consist primarily of basic supportive measures, in
recent years improved training in obstetric management
of high-risk pregnancies and perinatal care has resulted in
an improvement in standards of newborn care. Several
centers have thus begun to explore the possibility of im-
