About this study

Official title: Efficacy of Combined Palonosetron and Dexamethasone for Prevention of Post-operative Nausea and Vomiting in Patients Undergoing Gynaecological Laparoscopic Surgery

Postoperative nausea and vomiting (PONV) is a common complication after general anaesthesia, especially among female patients undergoing laparoscopic surgery. This randomized controlled trial evaluates whether combined palonosetron and dexamethasone is more effective than palonosetron alone in preventing postoperative nausea and vomiting after gynaecological laparoscopic surgery.

Eligible patients will be randomized into two parallel groups. The intervention group will receive palonosetron plus dexamethasone, while the comparator group will receive palonosetron alone. Patients will be followed for 24 hours after surgery for incidence and severity of nausea and vomiting, rescue antiemetic requirement, adverse effects, patient satisfaction, and haemodynamic parameters.

Read the detailed description

Postoperative nausea and vomiting (PONV) is a common and distressing complication following general anaesthesia, particularly among female patients undergoing laparoscopic surgical procedures. Although several medications are available for prevention of PONV, no single agent completely eliminates the risk because multiple physiological and surgical factors contribute to its development.

Palonosetron is a second-generation serotonin (5-hydroxytryptamine-3 or 5-HT3) receptor antagonist with a prolonged duration of action and strong receptor affinity. It reduces nausea and vomiting by blocking serotonin-mediated pathways involved in the vomiting reflex. Dexamethasone, a corticosteroid with antiemetic properties, has also been shown to enhance the effectiveness of other antiemetic medications through multiple mechanisms, including modulation of inflammatory pathways and enhancement of antiemetic receptor sensitivity.

This randomized controlled trial is designed to evaluate whether adding dexamethasone to palonosetron provides improved prevention of postoperative nausea and vomiting compared with palonosetron alone in patients undergoing gynaecological laparoscopic surgery under general anaesthesia.

Participants will be randomly assigned to receive either combined palonosetron and dexamethasone or palonosetron alone before induction of anaesthesia. All participants will undergo standardized anaesthetic management and postoperative monitoring. The study will assess the effectiveness and safety of these preventive strategies during the postoperative period.

The findings of this study may provide additional evidence regarding the role of combination antiemetic therapy in improving postoperative recovery, patient comfort, and satisfaction after laparoscopic gynaecological procedures. The results may contribute to optimizing perioperative care practices and improving the management of patients at risk of postoperative nausea and vomiting.

What is being measured

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

  1. Incidence of postoperative nausea and vomiting

    Occurrence of nausea and vomiting episodes during the postoperative period (0-24 hours).

    Measured: 24 hours after surgery

Secondary outcomes (9)
  1. Severity of postoperative nausea and vomiting

    Severity of nausea and vomiting will be assessed using the Visual Analogue Scale (VAS), where 0 indicates no nausea and 10 indicates the worst possible nausea. The severity will be evaluated and compared between the two study groups during the postoperative period.

    Measured: 1 hour, 3 hours, 6 hours, 12 hours, and 24 hours after surgery

  2. Requirement of rescue antiemetic medication

    The requirement for rescue antiemetic medication will be recorded and compared between groups. Patients experiencing significant nausea or vomiting (VAS score ≥4) will receive rescue antiemetic treatment with intravenous metoclopramide 10 mg, and the total requirement will be documented.

    Measured: During the first 24 hours after surgery

  3. Incidence of adverse effects related to study drugs

    Drug-related adverse effects, including dizziness, headache, and arrhythmia, will be monitored and compared between the study groups using a four-point severity scale.

    Measured: During the first 24 hours after surgery

  4. Patient satisfaction after surgery

    Patient satisfaction regarding postoperative recovery and nausea-vomiting management will be assessed using a 5-point Likert satisfaction scale, where 1 indicates very dissatisfied, and 5 indicates very satisfied. Higher scores indicate greater patient satisfaction. The satisfaction scores will be compared between the two study groups.

    Measured: At 24 hours after surgery

  5. Postoperative systolic blood pressure (SBP)

    Systolic blood pressure will be measured and compared between the palonosetron-dexamethasone group and the palonosetron alone group during the postoperative period.

    Measured: At 1, 6, 12, and 24 hours after surgery

  6. Postoperative diastolic blood pressure (DBP)

    Diastolic blood pressure will be measured and compared between the study groups during postoperative follow-up.

    Measured: At 1, 6, 12, and 24 hours after surgery

  7. Postoperative mean arterial pressure (MAP)

    Mean arterial pressure will be recorded and compared between the two study groups during the postoperative period.

    Measured: At 1, 6, 12, and 24 hours after surgery

  8. Postoperative heart rate (HR)

    Heart rate will be monitored and compared between the palonosetron-dexamethasone group and the palonosetron alone group after surgery.

    Measured: At 1, 6, 12, and 24 hours after surgery

  9. Postoperative oxygen saturation (SpO₂)

    Peripheral oxygen saturation (SpO₂) will be measured using pulse oximetry and compared between the two study groups during postoperative follow-up.

    Measured: At 1, 6, 12, and 24 hours after surgery

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 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 10 Sep 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 Bangladesh. 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 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?

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?

Incidence of postoperative nausea and vomiting (time frame: 24 hours after surgery). 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 NCT07813897, which also lists 17 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 10 Sep 2026.
