  Purpose

Labor pain is universal and occurs acutely. This is the most painful experience in a woman's life. Pain relief during labor is expected to have positive impact on the progress, outcome and cost of labor. However, it is controversial whether labor analgesia shortens the length of labor and influences progression to cesarean.Labor analgesia can be performed via spinal, epidural or systemic routes (intravenous or intramuscular). Opioid agonists (meperidine, fentanyl etc.) as well are the systemic agents frequently used for labor analgesia.Results of the studies concerning effect of meperidine on the length of labor are controversial.

Many studies have expressed that meperidine has no effect or effect on the progress of labor.This study aims to evaluate the effect of meperidine on the length of active phase of labor in nulliparous or multiparous women, who will be randomized into case and control groups.

Primary Outcome Measures:
  • The duration of active phase of labour [ Time Frame: 24h ] [ Designated as safety issue: Yes ]
    The primary outcome is to evaluate whether meperidine is effective in shortening the duration of the active phase of labor


Secondary Outcome Measures:
  • mode of delivery [ Time Frame: 24h ] [ Designated as safety issue: Yes ]
    The secondary outcome is to determine the mode of delivery either ceasarean or vaginally when meperidine is used

  • duration of the second stage of labour [ Time Frame: 24h ] [ Designated as safety issue: Yes ]
  • need of oxytocin augmentation [ Time Frame: 24h ] [ Designated as safety issue: Yes ]
  • meconium-stained liquor [ Time Frame: 24h ] [ Designated as safety issue: Yes ]
  • instrumental delivery rate [ Time Frame: 24h ] [ Designated as safety issue: Yes ]
  • maternal satisfaction score for the birth process obtained within 24 h of delivery [a visual analog scale (VAS) of 0-10, with higher score denoting greater satisfaction] [ Time Frame: 24h ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 440

Arms Assigned Interventions
Active Comparator: meperidine administration group
Infusion bags were prepared and labelled as Bag A (meperidine group), containing 50 mg meperidine (Aldolan; Liba Laboratuarları, Istanbul, Turkey) in 9 mL normal saline solution. Providers and patients were blinded to the contents of the bags until the conclusion of the study. Meperidine or placebo were administered by slow intravenous infusion in about 2 minutes by means of injectors containing 10 mL of solution.
Drug: Meperidine
50 mg meperidine injection intramusculer
Other Name: aldolan
Placebo Comparator: plasebo group
Bag B (placebo group), containing 10 mL of normal saline solution. Providers and patients were blinded to the contents of the bags until the conclusion of the study.Meperidine or placebo were administered by slow intravenous infusion in about 2 minutes by means of injectors containing 10 mL of solution.
Drug: Placebo
Bag B (placebo group), containing 10 mL of normal saline solution

Detailed Description:
  • Participant eligibility for the study included gestational age between 34 and 42 weeks, live fetus, cephalic presentation, and were in active phase of labour with well-establish uterine contractions (3 contractions within 10 min) and cervical dilatation between 3 and 5 cm with a partially effaced cervix ( %70 or more ).
  • Exclusion criteria are placenta previa, placental abruption, caesarean section or any uterine scarring, abnormal placentation (accreta, increta, or percreta), multiple gestation, fetal macrosomia (≥4000 g), suspicious of cephalopelvic disproportion, meperidine allergy, use any kind of labour induction or augmentation before on admission for delivery in our hospital.
  • A Simple randomisation using a random-number table was performed by the investigational pharmacy staff, who took no further part in the study.
  • The primary outcome of interest in this study is the labor duration.
