About this study

Official title: Pre-emptive Single Intravenous Lidocaine Dose to Prevent Post-Fundal Pressure Headache During Cesarean Section: The LID-HEAD Multi-center Randomized Controlled Trial

This prospective randomized controlled multicenter study will be conducted to evaluate the effects of pre-emptive IV lidocaine dose on the incidence and severity of intraoperative headache that may occur after the extra-abdominal manual uterine fundal pressure in patients undergoing cesarean section under spinal anesthesia.

Read the detailed description

This fundal pressure was previously evaluated for its effect on maternal hemodynamics during cesarean section. The investigators observed in their practice that a complaint of headache is reported by a percentage of patients immediately after fundal pressure and fetal delivery. Despite its small percentage, it had a negative impact on the maternal experience.

The proposed mechanism of this headache may be attributed to the fundal pressure-induced cushing reflex, vasopressin response, or cerebral venous engorgement all resulted from the increase in intra-abdominal pressure which can be reflected on the intra-thoracic pressure and the intracranial pressure (ICP).

Lidocaine is a local anesthetic that, when given via intravenous (IV) route could attenuate the rise in ICP during tracheal suctioning, and decrease the optic nerve sheath diameter distension during endotracheal intubation and during laparoscopy. These effects could be established by reducing cerebral blood volume through its vasoconstrictive effects on the cerebral vasculature and by decreasing electrical activity and metabolic demands through its inhibitory effects on sodium channels.

The fundal pressure maneuver is supposed to produce pathophysiological changes that resemble the previously reported factors that led to ICP elevation (intubation and pneumo-peritoneum). So, this study will be conducted as the investigators hypothesize that the administration of single IV lidocaine dose shortly before uterine fundal pressure may attenuate the temporary rise in ICP which may decrease the incidence of headache.

What participants receive

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

  • Lidocaine IVDrug

    IV lidocaine 1.5 mg/kg (diluted with 0.9% isotonic saline to a total volume of 10 ml) over 5 minutes with the start of skin incision after ensuring negative baseline headache.

  • Saline 0.9%Other

    IV 10 ml isotonic saline over 5 minutes with the start of skin incision after ensuring negative baseline headache.

What is being measured

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

  1. Incidence of intraoperative headache

    The incidence of intraoperative headache that may occur after fundal pressure application until the end of surgery will be recorded.

    Measured: Up to the end of surgery.

Secondary outcomes (6)
  1. Severity of intraoperative headache

    The numerical rating scale (NRS) scores which is a 11-point scale ranging from 0= no pain to 10= most severe pain will be used to evaluate the severity of headache.

    Measured: Up to the end of surgery.

  2. The changes in optic nerve sheath diameter

    Optic nerve sheath diameter will be assessed by ultrasound before spinal block, at skin incision, after fetal delivery, and at the end of surgery.

    Measured: Up to the end of surgery.

  3. Incidence of shoulder pain

    The incidence of shoulder pain that may occur intraoperatively and up to 24 hours after surgery will be recorded by asking the patients if they have any pain in their shoulder area. The numerical rating scale (NRS) scores which is a 11-point scale ranging from 0= no pain to 10= most severe pain will be used to evaluate the severity of shoulder pain.

    Measured: Up to 24 hours after surgery.

  4. Neonatal Apgar (appearance, pulse, grimace, activity, and respiration) scores

    Neonatal Apgar scores which include five signs (appearance, pulse, grimace, activity, and respiration) will be recorded at 1 min and 5 minutes after delivery. Each sign has a score of 0, 1, 2 with a total score of 10. Scores more than 6 indicate normal good health.

    Measured: Up to 5 minutes after delivery.

  5. side effects

    Nausea and vomiting, hypotension and bradycardia will be recorded

    Measured: Intraoperative up to 1 hour after surgery.

  6. Incidence of postoperative headache

    The incidence of any headache that may occur from the end of surgery up to 24 hours after surgery will be recorded.

    Measured: Up to 24 hours after surgery.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Lidocaine IV and Saline 0.9% in people with Intravenous Lidocaine and Fundal Pressure, run by Tanta University at 1 site in Egypt.

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 3 inclusion and 7 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: looking for participants now, as of the sponsor's last update on 6 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.

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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 Osama M Rehab, MD (+201095210806, osamarehab@med.tanta.edu.eg), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of intraoperative headache (time frame: Up to the end of surgery.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 6 Jul 2026.
