About this study

This is a prospective, randomized, blinded, sham controlled regional anesthetic (supra-orbital and infra-orbital nerve block) pain study to compare the systemic postoperative pain medication requirements in patients having Trans-sphenoidal Pituitary surgery. The patients will receive general anesthesia +/- regional anesthesia for trans-sphenoidal pituitary surgery and systemic pain medication during the intra-operative and postoperative (6hrs) period. The amount of systemic pain medication requirements will be compared between those patients receiving regional and general anesthesia versus general anesthesia alone.

Read the detailed description

Combined regional and general anesthesia for surgery is known to provide superior pain control in the peri-operative period (intra and post-operative). Of particular interest in neurosurgery are more rapid patient awakening and earlier ability to perform adequate post-operative neurological exam. In addition to this, regional anesthesia can decrease the total amount of systemic pain medications necessary and thus decrease their associated side effects. Consequently, less systemic pain medications can benefit the patient in many ways.

By modifying the postop pain regime to include intraoperative regional anesthesia, there could be increased patient satisfaction, and significant economic gains to the hospital through a more streamlined, shorter, more pleasant hospital course for the patient. Patients who have this trans-sphenoidal pituitary surgery are usually same day admission patients who, following their surgery, are admitted for up to 24 hours postoperatively. Usually prolonged admissions result from headache and nausea +/- vomiting. Etiology of the headache is likely multifactorial. One theory is that stimulation of the peripheral trigeminal (Cranial Nerve Number V) fibers in the V1 and V2 distribution of the face by the surgical endoscope and surgical trauma may lead to release of inflammatory mediators and post-operative migraine. It has been shown that repetitive injection of local anesthetics in the distribution of supra-orbital nerve V1 and infra-orbital nerve V2 can decrease the incidence of chronic idiopathic migraine headaches not related to surgery. By administering regional anesthesia to the patient intra-operatively during their general anesthetic for the surgery, pain scores may be reduced, PONV (postoperative nausea and vomiting) decreased, and hospital stay shortened.This study will be examining the use of regional anesthesia (infra-orbital and supra-orbital nerve blocks) combined with general anesthesia versus general anesthesia to observe the systemic opioid consumptions of adult transsphenoidal pituitary surgery patients. Secondary endpoints of the study will be: (1) presence of PONV, (2) time in PACU (post anesthesia care unit) and finally, (3) duration of hospital stay until discharge.

What is being measured

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

  1. 6 hour post-operative Morphine Requirements in milligrams (mg)

    Systemic Intravenous (IV) morphine opioid consumption in mg in 2 groups during first 6 hours post-operatively (regional + general versus only general anesthesia)

    Measured: 6 hours post-op

Secondary outcomes (4)
  1. Pain exposure postoperative for 6 hours

    Pain score out of max 10 (Scale 0-10). "O" (no Pain) and "10" (worst possible pain)

    Measured: 6 hours

  2. Nausea and/or vomiting for 6 hours postoperatively

    Nausea score out of max 10 (Scale 0-10)."O" (no nausea) and "10" (worst nausea possible). Presence of vomiting is minimum score of 5/10.

    Measured: 6 hours

  3. Time to discharge from Post anesthesia care unit (PACU) in minutes

    Time patient spends in PACU from entry time until discharge to the floor in minutes

    Measured: post-operative period measured in minutes up to 120 minutes

  4. Time to discharge from hospital in minutes

    Time measured in minutes from surgery start to discharge from the hospital

    Measured: post-operative time up to 36 hours

Questions about this trial

What is this clinical trial studying?

A study testing Nerve Block with ropivicaine 0.5% Injectable Solution in people with Post-operative Surgical Pain, run by University of California, San Francisco at 1 site in United States.

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 12 inclusion and 5 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: finished, as of the sponsor's last update on 17 Dec 2020. 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 United States. 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

6 hour post-operative Morphine Requirements in milligrams (mg) (time frame: 6 hours post-op). 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 NCT04670614, which also lists 1 linked publication.

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 17 Dec 2020.
