Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Group A | Participants receive a low dose of Tranexamic acid (10mg/kg) administered slowly over 5 minutes intravenously (iv) 10 minutes prior to skin incision in elective caesarean section with prophylactic oxytocin (5 IU iv) slow administration on delivery of the baby.~Tranexamic Acid: TXA (10mg/kg) solution for injection from the vial will be diluted with 100 - 200ml electrolyte solution such as Normal Saline, Ringers solution, dextrose/water for injection on the same day it is to be used (i.e. when anaesthetist notes the patient has been randomized to receive TXA). Intravenous administration should be at a rate of 100mg or fraction thereof over at least 1 minute - usually at least 5 minutes. Standard practice is to administer over 20 minutes. Administration is to be done at least 10 minutes prior to skin incision.~Oxytocin: 5IU of oxytocin are administered intravenously slowly once the baby has been delivered at caesarean section. | 0 | 224 | OG000 |
| Group 2 | Group B | Participants receive prophylactic oxytocin (5 IU iv) slow administration on delivery of the baby~Oxytocin: 5IU of oxytocin are administered intravenously slowly once the baby has been delivered at caesarean section. | 2 | 227 | OG001 |
