Brief Summary:
The objective of this study is to investigate whether topical application of tranexamic acid into the uterine cavity and the surgical site intra-operatively can reduce blood loss and provide better surgical haemostasis in parturients with moderate to high risk for bleeding undergoing caesarean deliveries.

Arm Intervention/treatment
Active Comparator: Tranexamic acid (TXA) Group
Subjects in the TXA group will receive the topical tranexamic acid solution which will be administered intra-operatively, during the caesarean section on the surgical wound and into the intrauterine cavity after the delivery of the baby and the placenta. 60mls of the solution will be applied topically to the placental bed as identified by the surgeon carrying out the surgery by spraying the study solution using a syringe into the uterine cavity. Another 30mls of the solution will be applied to the open incision wound. The surgeon will then proceed to close the first layer of the uterus in the usual manner. The remaining 30mls of the study drug solution is then applied topically on the closed incision wound
Drug: Topical tranexamic acid
Topical tranexamic acid 2g diluted with normal saline 0.9% to a volume of 120mls solution (Concentration 16.7mg/ml)
Other Name: TXA group

Sham Comparator: Control Group
Subjects in the Control group will receive topical normal saline solution which will be administered intra-operatively in the same manner as described for the TXA group.
Drug: Normal saline 0.9%
Sterile Normal saline 0.9% 120mls solution
Other Name: Control group

Primary Outcome Measures :
  1. Total intra-operative blood loss in the Tranexamic Acid (TXA) group compared to the Control group [ Time Frame: From the start of the surgery (first surgical incision) up to the end of the surgery (at wound closure) ]

    Total intra-operative blood loss will be measured at the end of the surgery (at wound closure).

    The following formula will be used:

    Total intra-operative blood loss (ml) = A + B - C where A = Blood volume in suction bottle (ml) B = Wet weight of all gauzes and drapes soaked with blood (g) C = Dry weight of all gauzes and drapes soaked with blood (g) (assumption of 1 gram of blood is equivalent to 1ml of blood) The blood loss quantified will be documented in subjects case report form

Secondary Outcome Measures :
  1. Transfusion requirements in terms of number of red blood cell packets transfused up to 24 hours post surgery [ Time Frame: From start of surgery (first surgical incision) up to 24 hours post surgery (wound closure) ]
    The number of red blood cell packets (number of pints) transfused in all patients from the start of the surgery up to 24 hours post surgery will be documented in each subject's case report form and the transfusion requirements will be compared between both groups.

  2. Haematocrit trends at baseline (Pre-operative) and at 6 hours post surgery in the TXA group and the Control group [ Time Frame: Pre-operatively within 24 hours prior to start of surgery (before surgical incision) up to 6 hours from the end of surgery (wound closure) ]
    Subjects full blood count will be taken pre-operatively within 24 hours prior to start of surgery (baseline) and at 6 hours from the end of the surgery (wound closure) to measure the haematocrit trends in both study groups and these values will be documented in the case report form
