The Association of Shock Index and Haemoglobin Variation With Postpartum Hemorrhage After Vaginal Delivery: A Prospective Cohort Pilot Study

Objective: This study was aimed to compare the shock index (SI) values between patients who required blood transfusion due to postpartum hemorrhage (PPH) and patients who received no blood transfusion. Methods: We conducted this cross-sectional study at a tertiary center between January 2019 and June 2019. A total of 2534 patients who underwent vaginal delivery were included in this study. We measured SI values upon admission, 30 minutes, 1-hour, and 2-hours after delivery. We identified women who required blood transfusion as the study group. Control patients who delivered in the same period and received no blood transfusion were identified in the medical record system and randomly selected. Age, parity, BMI, and SI values at each one prepartum and three postpartum periods of the groups were analyzed. Results: A total of 2534 patients were included in the study. A varying amount of blood transfusion was performed in 54 patients (2.13%). When we compared with patients who did not receive blood transfusion after delivery, patients who received any amount of blood transfusion after vaginal delivery had significantly higher SI values 30 minutes after delivery (0.99±0.20, and 085±0.11, p=0.0001), at 1-hour (1.00±0.18, and 0.85±0.11, p=0.0001), and 2-hours (1.09±0.16, and 0.87±0.11, p=0.0001). Conclusion: SI value could be a reliable and consistent marker to predict the requirement for any amount of blood transfusion due to PPH. doi: https://doi.org/10.12669/pjms.37.3.3444 How to cite this:Oglak SC, Obut M, Tahaoglu AE, Demirel NU, Kahveci B, Bagli I.

Background: The main aim of this study is to determine the maternal and fetal outcome of pregnancy among women with one previous caesarean section at term in relation to vaginal delivery, post partum complication, neonatal complication like low Apgar score, fetal weight and admission in special baby unit. Methods: This is a prospective and descriptive study done in a sample size of 100. Inclusion criteria were term pregnancy, single live fetus with cephalic presentation with one previous caesarean section. During study period total number of obstetric admissions was 3546 and 115 cases were admitted with previous one caesarean section. Result: Out of 100 cases, 31 cases had vaginal delivery and 69 cases had caesarean section. Among 31 vaginal deliveries, 24 cases had spontaneous vaginal delivery and 7 had assisted delivery with vacuum, main indication of vacuum delivery was to cut short the second stage of labor that was in 5(71.43%) cases. Among 69 caesarean section cases, 51 had emergency caesarean section and 18 had elective caesarean section and cephalopelvic disproportion was the main indication in both the groups. Most common complication was scar dehiscence and postpartum hemorrhage. There were two still births in each group and one minute APGAR score was slightly better in caesarean section. Conclusions: Patients with previous caesarean section are at high risk of repeat emergency or elective caesarean section. About one in three patients with previous caesarean section delivered vaginally. In the present study postpartum hemorrhage was the commonest complication, which was found in caesarean section, and only one puerperal pyrexia was seen in case of vaginal delivery.
