Study summary

Included women were divided randomly into two groups:

Group A: (n=100): women were subjected to application of EMLA® cream "Lidocaine-prilocaine cream (EMLAcream; Astra Zeneca, Basiglio, Italy is an entectic mixture of 2.5% lidocaine and 2.5% prilocaine)"for pain relief during episiotomy repair.

Group B: (n=100): women were subjected to application of local injection of 10 ml of 1% mepivacaine for pain relief during episiotomy repair.

Read the detailed description

During the second stage of labor, women were placed in the lithotomy position. 10- Patients who were enrolled in the study were guaranteed to obtain additional anesthesia during episiotomy repair whenever pain exceeded the tolerability threshold.

11- Volunteers were assigned randomly to have either local injection of 10 ml of 1% mepivacaine or application of 5gm-dose® EMLA cream"Lidocaine- prilocaine cream(EMLA cream; Astra Zeneca, Basiglio, Italy is an entectic mixture of 2.5% lidocaine and 2.5% prilocaine)" for pain relief during episiotomy repair.

  1. Group A: "EMLA group"

    • Women who were assigned randomly to receive EMLA cream had a 5gm dose of cream applied to the intact surface of the perineum and area covered with an occlusive dressing to facilitate pemetration thrug stratum corneum
    • EMLA cream was applied, 1 hour before the expected time of birth.
    • With the assistance at birth, the residue of cream was removed to prevent contact with the fetus, because sodium hydroxide, which is a component of the cream, can cause fetal eye irritation.
    • No additional anesthetic was applied if episiotomy was necessary.
    • Before commancement of perineal repair any residual cream was wiped off.
  2. Group B: "mepivacaine infiltration group".

    • In the mepivacaine group, 10 ml of 1% mepivacaine solution was injected slowly when the fetal head was crowned with frequent aspiration to avoid intravascular injection.
    • In the mepivacaine group, if an episiotomy was indicated, it was performed after infiltration of perineal tissue with 10 ml of 1% mepivacaine solution.
    • The suture procedure was delayed 10 minutes after the injection of the aneathetic
    • All episiotomies were performed at the top of contraction as mediolateral episiotomies.

      12- Episiotomy repair

    • In all cases episiotomies was repaired with a loose, continous, non locking suture to close the vaginal mucosa and the muscular layer of the perineum using vicryl Number zero (0).
    • The suture begins about 0.5 cms above the apex of the vaginal wound The suture are evenly placed to allow for approximation of the edges of the wound without causing tension or wrinkling or over lapping.
    • At the end of the vaginal mucosal repair care is taken to align the edges of the episiotomy wound to restore the appearance of the hymenal ring, the fourchette and the beginning of the perineal skin.
    • At the point where perineal skin begins; the suture is then passed beneath the vaginal mucosa, and repair of perineal muscle begins. The deep layer of muscles is closed first, ensuring no dead space one left behind, and ensuring no bleeding points are ignored.
    • The skin was closed with the same continuous suture to approximate the subcutinuous tissue.
    • The wound is cleared with antiseptic solution and covered by addressing. 14- Before leaving the delivery suite (approximately 2 hours after delivery) each patient was asked to record the severity of pain that she had experienced during perineal repair in a 10-cm visual analog scale, where 0 cm means no pain and 10 cm means unbearable pain.
    • The patient was asked to mark the point that best indicated the perception of her pain on the visual analog scale
    • Finally, women were asked to express their overall satisfaction with the anesthesia method during perineal repair with "yes" or "no" answers

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Aug 2017; primary completion for Mar 2018, 7 months later.

Of 280 non-industry phase 4 interventional studies under Pain, half reached primary completion within 18 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 35. This study's planned 7 months is below that.

Counting every sponsor, half of 295 studies reached it within 18 months; a quarter within 8 and three quarters within 33.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 29, 2017, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
