Brief Summary

Labour is a very painful experience and epidural analgesia is considered the gold standard for pain relief in labour. Epidural scarcity, cost and shortage of skilled personnel to administer it is a limitation to it's usage in developing countries. Parenteral opioid analgesics such as pethidine and pentazocine are effective labour analgesia commonly used in developing countries but are limited by their side effects. This limitation in their use call for the need for alternative analgesic with similar or superior analgesic effect but with minimal side effects.The study is aimed at evaluating the efficacy and safety of combined tramadol and paracetamol in reducing labour pain among parturients.

Outcome Measures

Primary Outcomes (6)

  • To Evaluate the Number of Participants with Pain After 1 hour of Analgesia Administration

    Pain was Assessed during Labour 1 hour Post Analgesia Administration using the Numerical Rating Scale for Pain. The Numerical Rating Scale has a minimum score of 0, a maximum score of 10 and a range of 0-10, where higher score means a worse outcome (0=No Pain at all, 5 means Moderate Pain and 10= Worse pain imaginable)

    1 hour post analgesia administration

  • To Evaluate the Number of Participants with Pain After 2 hours of Analgesia Administration

    Pain was Assessed during Labour 2 hours Post Analgesia Administration using the Numerical Rating Scale for Pain. The Numerical Rating Scale has a minimum score of 0, a maximum score of 10 and a range of 0-10, where higher score means a worse outcome (0=No Pain at all, 5 means Moderate Pain and 10= Worse pain imaginable)

    2 hours post analgesia administration

  • To Evaluate the Number of Participants with Pain After 3 hours of Analgesia Administration

    Pain was Assessed during Labour 3 hours Post Analgesia Administration using the Numerical Rating Scale for Pain. The Numerical Rating Scale has a minimum score of 0, a maximum score of 10 and a range of 0-10, where higher score means a worse outcome (0=No Pain at all, 5 means Moderate Pain and 10= Worse pain imaginable)

    3 hours post analgesia administration

  • To Evaluate the Number of Participants with Pain 4 hours After Analgesia Administration

    Pain was Assessed during Labour 4 hours Post Analgesia Administration using the Numerical Rating Scale for Pain. The Numerical Rating Scale has a minimum score of 0, a maximum score of 10 and a range of 0-10, where higher score means a worse outcome (0=No Pain at all, 5 means Moderate Pain and 10= Worse pain imaginable)

    4 hours post analgesia administration

  • To Evaluate the Number of Participants with Pain 5 hours After Analgesia Administration

    Pain was Assessed during Labour 5 hours Post Analgesia Administration using the Numerical Rating Scale for Pain. The Numerical Rating Scale has a minimum score of 0, a maximum score of 10 and a range of 0-10, where higher score means a worse outcome (0=No Pain at all, 5 means Moderate Pain and 10= Worse pain imaginable)

    5 hours post analgesia administration

  • Number of Participants with Treatment Related Adverse Events on both arms

    Number of Participants with Treatment Related Adverse Events such as Nausea, Vomiting, Hypersensitivity Reaction, respiratory depression and any other Adverse Effects from the time of first administation to 2 hours post delivery

    Time of first analgesia administration to 2 hours Post Delivery

Secondary Outcomes (4)

  • Participants with Good Service Satisfaction

    First 5 hours Post Delivery

  • Analgesia Administration to Delivery interval

    First 2 hours Post Delivery

  • Apgar Scores of the Neonates

    At first and fifth minutes after birth

  • Special Care Baby Unit Admissions

    First 2 hours Post Delivery

Masking Details
The hospital Pharmacist will prepare the drugs in both arms where the first arm will be 2 ml of 100mg tramadol in 5 ml syringe and 2ml of 600mg Paracetamol in 5 ml syringe as well. The second arm will be 2ml of 30mg pentazocine in 5ml syringe plus 2ml of water for injection. Both arms of the medications will be pre-packed in opaque envelopes and labelled by the pharmacist as either A or B who will take no further part in the study. These will be assigned based on the randomized outcome. The randomization list will be on the possession of research assistant who will take no further part in the study after randomly assigning participants to the study arms till the end of the study.
