About this study

Official title: Incidence of Residual Neuromuscular Blockade in Patients With Frailty Undergoing Gynecologic Cancer Surgery

Frailty among patients undergoing surgery is strongly associated with an elevated risk of adverse perioperative outcomes, heightened incidence of postoperative complications, increased mortality rates, and prolonged hospital length of stay. Our focus centers on investigating the frailty index in the context of complications experienced by patients undergoing oncologic gynecology surgery. The principal objective of this research is to elucidate the extent to which residual neuromuscular blocking agents are linked to frailty.

Read the detailed description

Among patients undergoing oncologic gynecological procedures, such as those for vulvar cancer, endometrial cancer, and ovarian cancer, the incidence of frailty has been observed to range from 14% to 45%. Frailty directly influences the metabolism of anesthetic agents and intraoperative management. Furthermore, the prevalence of residual neuromuscular blocking agents following surgery can be as high as 26% to 53%. No prior research has investigated the correlation between residual muscle relaxants and frailty in gynecologic oncology patients. This study is designed to assess the prevalence of residual muscle relaxants in these patients with frailty. Additionally, data on the incidence of frailty and its impact on postoperative outcomes and prognosis in patients undergoing gynecologic oncology surgery will be collected and reported.

What is being measured

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

  1. Incidence of residual neuromuscular blockade

    Incidence of residual neuromuscular blockade with the relation of frailty after gynecologic oncology surgery

    Measured: 0-30 minute after surgery

  2. Incidence of frailty

    Incidence of frailty in patients undergoing gynecologic oncology surgery

    Measured: 0 - 24 hours preoperative

Secondary outcomes (9)

    Measured: Throughout Intraoperative period, an average 3-5 hours

  2. Rate of blood transfusion

    Quantity of units blood transfusion

    Measured: Throughout Intraoperative period, an average 3-5 hours to 24 hours postoperative

  3. Rate of vasopressor usage

    Measured: Throughout Intraoperative period, an average 3-5 hours to 24 hours postoperative

  4. Length of hospital stay

    Total number of days of hospital stay

    Measured: Through study completion, an average of 1 year, an average 3 - 5 days

  5. Rate of intensive care unit admission

    Measured: 3 days after operation

  9. Mortality rate

    Number of patients who died after surgery

    Measured: 30 days after operation

Questions about this trial

What is this clinical trial studying?

A study testing Train of four nerve stimulator in people with Frailty and Neuromuscular Blockade, run by Mahidol University at 1 site in Thailand.

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 2 inclusion and 4 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 6 Oct 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 Thailand. 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.

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 residual neuromuscular blockade (time frame: 0-30 minute after surgery). The study lists 2 primary outcomes in all. 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 NCT06216002.

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 Oct 2026; AzTrials last refreshed its copy on 8 Nov 2026.
