Trial summary

Injection of intraperitoneal bupivacaine revealed an analgesic effect whether injected alone or in combination with other adjuvants, which increase duration of analgesia and decrease the dose of administered bupivacaine thus minimizing its side effects e.g. Opioids, Corticosteroids and Magnesium sulphate.

About this study

Official title: The Evaluation of the Analgesic Effect of Intraperitoneal Bupivacaine Versus Bupivacaine With Neostigmine on Postoperative Pain in Laparoscopic Cholecystectomy:A Prospective, Randomized, Comparative, Double-blind Study.

Injection of intraperitoneal bupivacaine revealed an analgesic effect whether injected alone or in combination with other adjuvants, which increase duration of analgesia and decrease the dose of administered bupivacaine thus minimizing its side effects e.g. Opioids, Corticosteroids and Magnesium sulphate.

Neostigmine, a cholinesterase inhibitor that produces muscarinic receptor-mediated analgesia, increased postoperative analgesia when combined with local anaesthetics. Peripheral afferent nerve fibres contain muscarinic receptors, these could be a good target for pain suppression.

Read the detailed description

The use of neostigmine as adjuvant to intraperitoneal bupivacaine was not previously investigated. In this study the investigators will compare the analgesic effect of bupivacaine alone and bupivacaine in combination with neostigmine when injected intraperitoneal in patients undergoing laparoscopic cholecystectomy.

What participants receive

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

  • Bupivacaine HydrochlorideDrug

    Also called Marcaine

    after induction of general anesthesia and before the start of surgery, after inflating the pneumoperitoneum and before any surgical manipulation, the surgeon infuse 50 mL of blinded solution (bupivacaine or bupivacaine neostigmine) intraperitoneally to the sub-diaphragmatic space and gall bladder area guided by the camera and the patients are kept in Trendelenburg position for 5-10 minutes. Thereafter all patients will be positioned in the anti-Trendelenburg position to start the surgery and the laparoscopic procedure will be carried out in a standard fashion.

  • NeostigmineDrug

    Also called prostigmin

    after induction of general anesthesia and before the start of surgery, after inflating the pneumoperitoneum and before any surgical manipulation, the surgeon infuse 50 mL of blinded solution (bupivacaine or bupivacaine neostigmine) intraperitoneally to the sub-diaphragmatic space and gall bladder area guided by the camera and the patients are kept in Trendelenburg position for 5-10 minutes. Thereafter all patients will be positioned in the anti-Trendelenburg position to start the surgery and the laparoscopic procedure will be carried out in a standard fashion.

What is being measured

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

  1. Time of first analgesic requirements (in hours) after extubation

    hours

    Measured: 24 Hours post-operatively.

Secondary outcomes (5)
  1. • Total dose of intravenous pethidine (mg/24 hours).

    milligram

    Measured: 24 hours

  2. • The use of intra-operative rescue analgesia.

    milligram

    Measured: intraoperative period

  3. • The severity of post-operative shoulder pain assessed by visual analogue scale

    segmented numeric version of the visual analog scale (VAS) in which a respondent selects a whole number (0-10 integers) that best reflects the intensity of their pain 0 (no pain), 10(worst pain). The common format is a horizontal bar or line

    Measured: 24 Hours post-operatively.

  4. • The severity of post-operative abdominal pain assessed by visual analogue scale

    segmented numeric version of the visual analog scale (VAS) in which a respondent selects a whole number (0-10 integers) that best reflects the intensity of their pain 0 (no pain), 10(worst pain). The common format is a horizontal bar or line

    Measured: 24 hours posoperatively

  5. • Post-operative nausea and vomiting assessed by postoperative nausea and vomiting score

    A simplified risk score for predicting postoperative nausea and vomiting female gender, history of PONV and/or motion sickness, non-smoking status, and postoperative use of opioids. When 0, 1, 2, 3, or 4 factors are present, the risk of postoperative nausea and vomiting is 10%, 20%, 40%, 60%, or 80%, respectively

    Measured: 24 hours postoperatively

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Bupivacaine Hydrochloride and Neostigmine in people with Pain, Postoperative, run by Kasr El Aini Hospital 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 4 inclusion and 6 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 3 Sep 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 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. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

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?

Time of first analgesic requirements (in hours) after extubation (time frame: 24 Hours post-operatively.). 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 NCT04244097, which also lists 2 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 3 Sep 2020; AzTrials last refreshed its copy on 8 Nov 2026.
