Abstract: Background: Post-partum hemorrhage is a serious obstetrical emergency and one of the significant but curable cause of maternal morbidity and mortality. It always occurs suddenly and frequently also unpredictable and catastrophic. In this study SR vacuum cannula will be applied to create negative pressure inside the uterine cavity with a specifically designed cannula which is a simple, safe and cost-effective technique.
Aim of the study: To know the efficacy of the SR suction cannula in the prevention of post- partum hemorrhage in high-risk pregnancy.
Materials and Methods: This interventional study was conducted in Department of Obstetrics and Gynecology, Shri B M Patil Medical College and Research Centre, Vijayapura, Karnataka. Patients admitted in labor ward with diagnosis of high-risk pregnancy prone for atonic PPH between November 2020 to April 2022.
Study Design: A prospective interventional study.
Results: In this study, A total of 128 patients who were fulfilling the inclusion criteria were considered as subjects and divided into 2 groups, Group A – Application of SR cannula with injection Oxytocin 10 units given within 1 minute of delivery of baby and in Group B- only injection Oxytocin 10 units given within 1 minute of delivery of baby. The observation noted were: the average age group of study included are 24.36 years. Out of 64 patients in the group A 40 cases had only 100-150ml of blood loss and 2 cases had 150-200ml of blood loss but in group B all patients had blood loss above 200ml in which 39 cases had 250-300ml of blood loss and 14 had 300-350 ml of blood loss. Time taken to stop bleeding in group A was 2 min for 38 patients, 3 min for 28 cases. Where as in group B time taken to stop bleeding was 2 min in 10 cases 3 min in 28 cases, and 4 min in 25 cases, one case reached up to 5 min.
Conclusion: Based on our study we conclude that Postpartum hemorrhage (PPH) is an obstetrical emergency which can happen following any delivery. It is a major cause of maternal morbidity, and one of the top three causes of maternal mortality. Hemorrhage is the leading cause of the admissions to the intensive care unit and the most preventable cause of the maternal mortality. Prophylactic application of SR suction cannula in high-risk woman for atonic PPH averts catastrophic bleeding. SR suction cannula should be made part and parcel of normal delivery tray to facilitate quick application. This simple and cost-effective technique takes very little time to organize and can stop bleeding within 2-3 minutes in atonic PPH as shown in this study. But in some cases, like complete atonic PPH it is not useful and they need surgical interventions And It gives time to arrange blood and blood products, shifting patients to tertiary care center or operation theatre. This life saving technique is useful in all settings especially in low resource settings. Its utilization in cases of inherited coagulopathies of pregnancy and DIC has to be further explored.
