Rupture of the pregnant uterus--a 20 year review

Nepal is a land-locked developing country located in between China and India with a population of 2.34 millions. The male: female ratio being 49:51 and very high maternal mortality. (539/100,000 live birth-1996) The geography of the country makes the situation very much divergent and difficult to cater the health services, especially operative procedures in remote places. THE AIMS OF THE STUDY ARE:- 1. To find out the incidence of R.U, distance from where the patients came, age, parity antenatal attendance, type of rupture, type of intervention and foetal outcome. 2. To suggest the concerned authorities to focus their attention to strengthen and expand comprehensive emergency obstetric care service (CEOCS) in remote areas of the country.

This is a retrospective study of rupture of pregnant uterus (RU) after 28 weeks of pregnancy for the period of 20 years from 1985 to 2005 A.D. (2042-2061 BS) admitted in the very busy tertiary centre for women (Maternity Hospital, Thapathali, Kathmandu.) with approximately 16000 deliveries and 11% Caesarean section rate per year. Available charts from hospital records of cases of R.U. admitted for the period of 20 years were analysed. During the period, 251 cases of R.U. were admitted.

There were 272245 live births, 25819 Caesarean section, 270 maternal deaths and 11197 perinatal foetal deaths, during the study period. Incidence of rupture of pregnant uterus was (0.09%) 1:1100 live-birth. There were 60% spontaneous, 29% scar rupture and 11% traumatic rupture. Maximum cases were brought from distance of more than 70 kilometres away, between 25-29 years of age, (mean age 28.7), of third and fourth gravida at 36-40 weeks of gestational period with 68% without antenatal attendance. Seventy percent (70%) had complete rupture. Sixty percent (60%) were managed with suture repair with bilateral tubal ligation, 24% had only repair and 15% had hysterectomy. The case mortality of R.U. (n=20) was 7.9%. Two percent (n=5) cases died before intervention due to arrival in moribund condition. Seventy five percent (75%) cases had stillborn babies. Conclusion More cases of RU are coming to the hospital due to better communication and awareness of the people outside the capital, and case- mortality is reduced compared to previous years.
