Clinical Trial Summary

This study seeks to determine if the using tranexamic acid prophylactically at caesarean section will prevent postpartum haemorrhage which is a major cause of maternal mortality in Zimbabwe and globally.

Description:

This trial will be an placebo-controlled, two-centre, randomized control trial with two parallel groups including 1,162 women who undergo elective or emergency caesarean deliveries at term. The study group will receive tranexamic acid (TXA) 1g intravenously at the onset of skin incision. There is normal saline placebo for the control group. The study and control groups will both receive the standard care offered at caesarean section including 5 IU of oxytocin intravenously on delivery of the baby. .

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants With Postpartum Hemorrhage (PPH)	Calculated estimated blood loss exceeding 1000ml. Estimated Blood Loss (EBL) was calculated using laboratory values of hemoglobin levels before and after procedure. Postpartum hemorrhage is defined as blood loss exceeding 1000mL after cesarean section.	Up to day 2 postpartum
Secondary	Blood Loss Using Hemoglobin Values	Calculated blood loss using hemoglobin values. A mean value of blood loss calculated using hemoglobin values	Up to day 2 postpartum
Secondary	Mean Blood Loss as Estimated by Obstetrician	Visually estimated blood loss at time of caesarean section. Attending obstetrician gave an estimated value of blood loss after delivery.	2 hours
Secondary	Occurrence of Postpartum Shock	Number of participants who had hypovolemic shock related to PPH as determined by assessing BP and pulse.	Up to day 2 postpartum
Secondary	Use of Supplementary Uterotonic(s)	Number of women requiring supplementary uterotonics	Up to day 2 postpartum
Secondary	Postpartum Transfusion	Number of women given postpartum transfusion	Up to day 2 postpartum
Secondary	Emergency Surgery for PPH	Number of participants who had emergency surgery for PPH including caesarean hysterectomies	Up to day 2 postpartum
Secondary	Change in Peripartum Haemoglobin	Mean change in haemoglobin concentration between the study group, calculated hemoglobin values at day 2 postpartum minus baseline hemoglobin values.	Up to day 2 postpartum
Secondary	Number of Participants With a Decrease in Peripartum Hemoglobin	Number of participants with a drop in hemoglobin more than 2g/dL or less than 2g/dL	Up to day 2 postpartum
Secondary	Change in Peripartum Haematocrit	Mean change in haematocrit percentage between the study groups from baseline to day 2 postpartum	Up to day 2 postpartum
Secondary	Admission Into Intensive Care Unit	Number of participants transferred to intensive care unit	Up to day 2 postpartum
Secondary	Death From Any Cause	Number of participants who died from any cause	Up to date of death or day 4 from admission
Secondary	Blood Pressure Measurements	Blood pressure at 15, 30, 45, 60, and 120 min after delivery	Up to 2 hours after the caesarean section
Secondary	Number of Mild Adverse Events	Number of mild events of nausea, vomiting, sensation of rings or spots of light in the visual field, dizziness	Up to 24 hours after administration
Secondary	Number of Severe Adverse Events	Deep vein thrombosis (if the diagnosis is confirmed by Doppler ultrasound); Pulmonary embolism (if the diagnosis is confirmed by radiological examination); Myocardial infarction; Seizure; Renal failure requiring dialysis	Up to day 3 postpartum
Secondary	Any Other Unexpected Adverse Event	Number of unexpected events during and after the adminstration of study drug and duration of observation	Up to day 3 postpartum
Secondary	Length of Hospital Stay	Duration of hospital admission in days	Up to day 3 postpartum
