About this study

Official title: Effect of Propofol Administration Time on the Incidence and Severity of Intrathecal Morphine-induced Pruritus in Parturient Undergoing Elective Cesarean Delivaries: A Prospective, Randomized, Comparative Controlled Study

Our hypothesis suggests that Administration time of intravenous propofol may affect Pruritus incidence and severity that occur after intrathecal morphine in parturient undergoing elective cesarean section (CS). the aim of the study is to investigate effect of prophylactic administration of intravenous sub-hypnotic dose of propofol before intrathecal morphine compared with the administration after intrathecal morphine on intrathecal morphine-induced pruritus incidence and severity in parturient undergoing elective cesarean delivaries.

Read the detailed description

Neuraxial Anaesthesia is a frequent anaesthetic approach for cesarean delivery and other lower abdominal and lower limb anaesthetic procedures. Neuraxial morphine addition to local anaesthetic provides an effective and prolonged postoperative analgesia, but has been associated with a frequent incidence of pruritus and postoperative nausea and vomiting (PONV).

Neuraxial opioids are thought to act on central nervous system pathways to cause pruritus. Although precise mechanisms are incompletely understood, Numerous interventions have been investigated to prevent opioid-induced pruritus in the peripartum period as: Opioid receptor agonist-antagonists, Serotonin receptor antagonists.

There is dense concentration of opioid receptors and 5-HT3 receptors in the dorsal part of the spinal cord and nucleus of the spinal tract of the trigeminal nerve in the medulla. Activation of these receptors by neuraxial opioid administration or by circulating estrogen in parturient results in pruritus which is usually localized to face, neck, or upper thorax.

Propofol exerts its antipruritic action through inhibition of the posterior horn transmission in spinal cord. Series of clinical trials have reported that a sub-hypnotic dose of propofol is equally effective in reducing the incidence of pruritus following intrathecal morphine. however these studies have limited information about dose and timing of administration of propofol.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Morphine intrathecalDrug

    patients intrathecal anaesthesia with morphine

  • propofolDrug

    patients will receive 0.5 mg/kg propofol diluted in 10 ml saline 0.9% IV injection 15 min before the end of surgery

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. severity of pruritus that occurs after intrathecal morphine in parturient undergoing elective cesarean section (CS) by pruritus Grading system.

    the pruritus grading score (PGS) score (Firas et al, 2012) for each patient which is based on: distribution, frequency, severity of itch, and quality of sleep

    Each patient's itch grade is calculated as the sum of the individual scores:

    Mild grade: if the total score is between 0 and 5. Moderate grade: if the total score is between 6 and 11. Severe grade: if the total score is between 12 and 19.

    Measured: 24 hours

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Morphine intrathecal and propofol in people with Cesarean Section, run by Assiut University.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 4 Dec 2024. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Esraa Essam Elsayed Mohamed, resident doctor (+201004879065, Esraa.16282364@med.aun.edu.eg), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

severity of pruritus that occurs after intrathecal morphine in parturient undergoing elective cesarean section (CS) by pruritus Grading system. (time frame: 24 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06715657, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Dec 2024.
