Tranexamic Acid vs Vasopressin in Placenta Previa Trial

Sponsor: Allama Iqbal Medical College

Summary

Placenta previa is a major obstetric condition associated with increased risk of excessive blood loss during cesarean section, leading to maternal morbidity and mortality. Different pharmacological agents have been used to minimize intraoperative hemorrhage. Tranexamic acid is an antifibrinolytic agent, while vasopressin reduces blood loss by causing vasoconstriction and myometrial contraction at the injection site. Both drugs have been used separately in placenta previa cases, however direct comparison between tranexamic acid and vasopressin is limited. This randomized controlled trial will be conducted at the Department of Obstetrics \& Gynecology, AIMC/Jinnah Hospital Lahore. A total of 58 women (29 in each group), aged 18-45 years, with singleton pregnancy and diagnosed placenta previa undergoing elective cesarean section will be included. Participants will be randomly allocated into two groups. Group A will receive 1 gram tranexamic acid diluted in 20 ml of 5% dextrose intravenously 15 minutes before cesarean section. Group B will receive 4 units vasopressin diluted in 20 ml normal saline injected at placental implantation site after delivery of placenta. The primary outcome will be intraoperative blood loss measured by gauze saturation assessment and suction drain measurement. The study will help determine which drug is more effective in reducing blood loss in placenta previa patients undergoing cesarean section.
