Study summary

The postoperative pain management after cesarean section under spinal anestheisa is done using various modalities. The commonly used regimens are systemic NSAIDs/Opioids, USG guided TAP block or Intrathecal additive Fentanyl or combined intrathecal fentanyl and USG guided TAP block.

Investigators aim to compare the postoperative analgesia in terms of time to the first rescue analgesic in parturients receiving intrathecal additive fentanyl only, or intrathecal fentanyl with USG guided TAP block or USG guided TAP block alone for elective CS done under hyperbaric bupivacaine spinal anesthesia.

Read the detailed description

Investigators will enroll 93 parturients planned for elective CS under hyperbaric bupivacaine spinal anesthesia and allocate them into three groups comprising intrathecal additive fentanyl only, or intrathecal fentanyl with USG guided TAP block or USG guided TAP block alone.

The primary outcome will be time to the first rescue analgesics.

What researchers measure

Primary outcomes

  1. To compare the time to the first rescue analgesics

    The time from the arrival to Postoperative care Unit to first complain of pain with Numeric Rating scale(NRS) greater than or equal to 4 among the Parturients Receiving Intrathecal Additive Fentanyl or Intrathecal Fentanyl With TAP Block or TAP Block Alone for Elective Cesarean Sections Under Hyperbaric Bupivacaine Spinal Anesthesia

    Time frame: Time to first complain of pain with Numeric Rating scale(NRS) greater than or equal to 4 within first 24 hours

Secondary outcomes

  1. Percentage of participants with treatment related side effects like pruritus, nausea and vomiting.

    To compare the side effects like pruritus, nausea and vomiting Among Parturients among the Parturients Receiving Intrathecal Additive Fentanyl or Intrathecal Fentanyl With TAP Block or TAP Block Alone for Elective Cesarean Sections Under Hyperbaric Bupivacaine Spinal Anesthesia

    Time frame: Time to first complain of pain with Numeric Rating scale(NRS) greater than or equal to 4 within first 24 hours

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

Ran from Aug 2022 to primary completion in Feb 2023, 6 months.

Of 2,089 non-industry interventional studies with no phase under Pain, Postoperative, half reached primary completion within 11 months of starting (the median), counting those still running; a quarter within 6 and three quarters within 23. This study's 6 months is below that.

Counting every sponsor, half of 2,102 studies reached it within 11 months; a quarter within 6 and three quarters within 23.

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 Mar 27, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
