The aim of this study was to determine the SB Department of Obstetrics and rate and to identify the likely causes contributing to SB. Gynaecology, Patan Hospital, Patan Academy of Health Methods: This cross-sectional study was conducted at Patan Hospital Sciences, Lalitpur, Nepal th th Email: from 15 June 2014 to 14 June 2017 for all the cases of SBs, at or after [email protected] 22 weeks, birth weight of 500 gm or more. The perinatal outcome, demographic profile, fetal characteristics, causes and contributing factors were analyzed. Results: There were 262 SB out of total 23069 deliveries, (11.24 per 1000) and 119 (46.12%) had antenatal check-up (ANC) at Patan Hospital. The 214 (82.95%) SB were among 20-34 years mothers, 133 (51.55%) being multigravida. Antepartum SB were 234 (89.31%), macerated 213 (81.30%), birth weight <1000gm 86 (32.82%) and male 156 (59.54%). The intrauterine growth restriction (IUGR) was present in 60 (22.90%), unexplained casue in 43 (16.41%), prematurity 28 (10.69%), congenital anomalies 26 (9.92%), pre-eclampsia 19 (7.25%), gestational diabetes, Peer Reviewers and abruptio placenta each 13 (4.96%). Delay in seeking care in 202 (78.30%) was a potential contributing factor. Prof. Dr. Paban Sharma Patan Hospital, PAHS Conclusions: The SB was 11.24/1000 births. The causes in descending order were IUGR, unexplained, prematurity, congenital anomalies, pre- eclampsia, gestational diabetes and abruptio placenta. Delay in seeking Prof. Dr. Jay N Shah care was found as a potential contributing factor.

Sarada Shrestha: Stillbirth at Patan Hospital INTRODUCTIONS stillbirths while those occurring after the onset of labour were classified as intrapartum Stillbirth, is defined by the World Health stillbirths. In this study, a fresh stillbirth was Organization (WHO) / the International defined as the intrauterine fetal death during Statistical Classification of Diseases (ICD) as labour or delivery where the fetus showed no the death of a fetus weighing 500 grams or signs of degenerative changes. Likewise, a more; if birth weight is unknown, by macerated stillbirth was defined as the gestational age of 22 weeks or more; or, if intrauterine fetal death sometime prior to both these criteria are unknown, by crown- delivery where the fetus showed signs of heel length of 25 cm or more.1 Stillbirth is one degenerative changes. Maternal age, parity, of the most common adverse outcomes of ANC, gestational age, presence or absence of pregnancy, accounting for half of all perinatal fetal heart sound during admission, type of mortality. Each year an estimated 4 million stillbirth, nature of stillbirth, mode of delivery, stillbirths are reported, with 98% occurring in presence of any obstetric complications, developing countries.2 Stillbirth rates are associated medical disorders, fetal sex, birth important indicators of the quality of weight of fetus; and factors potentially obstetric care available in any settings.3 contributing to the occurrence of stillbirth in terms of delay in seeking appropriate care: The aim of this study was to determine the (level-1 delay): because of household, society, stillbirth rate and to identify the likely causes financial challenges, delay in reaching contributing to stillbirth delivery which would healthcare facility; (level-2 delay): because of help to improve the quality of the existing delay in transfer from home to healthcare obstetric care at Patan Hospital. facility or to the referral center; (level-3 delay): delay in providing care in the hospital; METHODS and no delay were analyzed.
