A prospective survey was carried out in two Kathmandu hospitals and tw
o rural districts to establish urban and rural perinatal mortality rat
es (PNMRs) for these four centres in Nepal and to ascertain the causes
of perinatal mortality. All perinatal deaths occurring over a 1-year
period in the four centres were included (during which time there was
a total of 14 967 births). Cause of death was established by contempor
ary review of hospital case records or by structured questionnaire ('v
erbal autopsy') in the rural areas. The PNMRs in the hospitals were 48
.0 and 23.7 per thousand total births respectively, whilst those of th
e rural settings were 96.2 and 42.5 per thousand births. Perinatal asp
hyxia, low birthweight and infection were the most common causes but m
any of the deaths were unexplained. The high mortality rates were felt
to reflect the difficult circumstances of childbirth in Nepal. It was
concluded that a number of interventions would appear appropriate, bu
t that these should be introduced in a scientific manner.
