  Purpose

A double-blinded randomised control trial conducted in the Department of Obstetrics and Gynaecology of a tertiary hospital, Universiti Kebangsaan Malaysia Medical Centre (UKMMC) for two years duration from January 1st, 2012 till December 31st, 2013.

The aim of the study is to compare the haemodynamic and cardiovascular effects between intravenous carbetocin 100 μg and intravenous oxytocin 5 IU in women undergoing elective Lower Segment Caesarean Section (EL LSCS).

Study hypothesis: A single injection of carbetocin is haemodynamically and cardiovascularly safe and has similar efficacy in comparison to a single injection of oxytocin.

Primary Outcome Measures:
  • Haemodynamic effects [ Time Frame: 2 years ]
    1. Haemodynamic effect (blood pressure, heart rate, saturation of oxygen)
    2. Presence of ECG changes such as ST depression and changes in T-waves
    3. Presence of myocardial ischemia symptoms (such as chest pain, shortness of breath, feeling of heaviness in chest pain)
    4. To compare the troponin T levels


Secondary Outcome Measures:
  • Blood loss measurement [ Time Frame: 2 years ]
    1. Need for additional oxytocin infusion
    2. Total blood loss
    3. Drop in haemoglobin level post-operatively


Enrollment: 50
Study Start Date: January 2012
Study Completion Date: January 2014
Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Carbetocin
Carbetocin 100 µg, given as an intravenous bolus over 30 seconds others names are: duratocin, pabal
Drug: Carbetocin

IV carbetocin 100mcg, only in selected patient given as an intravenous bolus over 30 seconds by the anaesthetist following clamping of the umbilical cord only in patient that has been randomized to this group.

pitocin 5 IU also given as an intravenous bolus over 30 seconds by the anaesthetist following clamping of the umbilical cord only in patient that has been randomized to this group.

Other Names:

5 IU given as an intravenous bolus over 30 seconds by the anaesthetist following clamping of the umbilical cord only in patient that has been randomized to this group.
Other Name: pitocin

Detailed Description:

OUTCOME MEASURES systolic blood pressure (SBP), diastolic blood pressure (DBP), Heart Rate (HR), saturation of oxygen (SpO2) in certain time after drug injection.

The presence of myocardial ischemia symptoms and side effects of both drugs, ECG changes such as ST depression and changes in T-waves.

Hemoglobin and troponin-T level

The need for additional oxytocin infusion and estimated blood loss

The time interval between initial drug administration, type of additional oxytocic intervention that used and complication that happened.
