Study summary

Patients undergoing gynecological surgery are at high risk of developing postoperative sleep disorders. Intraoperative opioid use is detrimental to the patient's postoperative recovery of gastrointestinal function. Esketamine has sedative, hypnotic, analgesic, inflammatory response suppression, and antidepressant effects. Its hypnotic mechanism may be related to its rapid blockade of NMDA receptors and hyperpolarization-activated cyclic nucleotide-gated cation channels. Also can reduce the application of perioperative opioids, which in turn promotes the recovery of gastrointestinal function in patients after surgery.

Exclusion Criteria:

  1. Patient refusal;
  2. Known allergy to anesthetic drugs;
  3. Preoperative sleep disorder (Pittsburgh Sleep Quality Index [PSQI] > 7);
  4. Severe hypertension, coronary artery disease, cardiac insufficiency, pulmonary hypertension, pulmonary heart disease, increased cranial pressure, increased intraocular pressure, seizures, shift work, obstructive sleep apnea syndrome;

(7)hearing or visual impairment that precludes a scale assessment.

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

ASA physical status

The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

What researchers measure

Primary outcomes

  1. Changes in the level of actigraphy

    Through the actigraphy, monitor the patient's sleep quality.

    Time frame: Baseline (the night before surgery), postoperative nights 1 and 2

  2. Changes in the level of Pittsburgh sleep quality index

    Assess the patient's sleep quality by asking questions on the scale on a scale of 0-21, with higher scores representing poorer sleep quality.

    Time frame: Baseline (the night before surgery), postoperative nights 1, 2 and 3

Secondary outcomes

  1. Changes in the level of Mean Arterial Pressure

    The outcome above should be measured at the time before induction, after loading dose of intervention, at the beginning of surgery, upon surgery completion, immediately after extubation, and 30min after transfer to the post-anesthesia care unit.

    Time frame: Baseline (before induction), after loading dose of intervention, at the beginning of surgery, upon surgery completion, immediately after extubation, and 30min after transfer to the post-anesthesia care unit

  2. Changes in the level of IL-6

    The above results should be measured preoperatively, upon surgery completion, and on the 1st postoperative day.

    Time frame: Preoperatively, upon surgery completion, postoperative day 1

  3. Changes in the level of Melatonin

    The above results should be measured preoperatively, upon surgery completion, and on the 1st postoperative day.

    Time frame: Preoperatively, upon surgery completion, postoperative day 1

  4. Changes in the level of BDNF

    The above results should be measured preoperatively, upon surgery completion, and on the 1st postoperative day.

    Time frame: Preoperatively, upon surgery completion, postoperative day 1

  5. Changes in the level of IL-10

    The above results should be measured preoperatively, upon surgery completion, and on the 1st postoperative day.

    Time frame: Preoperatively, upon surgery completion, postoperative day 1

  6. Changes in the level of Heart Rate

    The outcome above should be measured at the time before induction, after loading dose of intervention, at the beginning of surgery, upon surgery completion, immediately after extubation, and 30min after transfer to the post-anesthesia care unit.

    Time frame: Baseline (before induction), after loading dose of intervention, at the beginning of surgery, upon surgery completion, immediately after extubation, and 30min after transfer to the post-anesthesia care unit

  7. Changes in the level of Oxygen saturation

    The outcome above should be measured at the time before induction, after loading dose of intervention, at the beginning of surgery, upon surgery completion, immediately after extubation, and 30min after transfer to the post-anesthesia care unit.

    Time frame: Baseline (before induction), after loading dose of intervention, at the beginning of surgery, upon surgery completion, immediately after extubation, and 30min after transfer to the post-anesthesia care unit

  8. Changes in the level of the visual analogue scale

    Assess the patient's pain by asking on a scale of 0-10, with higher scores representing more severe pain.

    Time frame: Postoperative days 1 and 2

  9. Recovery of gastrointestinal function

    Record the time of the first postoperative exhausting

    Time frame: Postoperative first 1 day

  10. Recovery of gastrointestinal function

    Record the time of the first postoperative bowel movement

    Time frame: Postoperative first 1 day

  11. Recovery of gastrointestinal function

    Record the time of the first postoperative feeding

    Time frame: Postoperative first 1 day

  12. Postoperative adverse reactions

    Record the occurrence of adverse reactions (nausea and vomiting, nightmares, dizziness, and mirages) on the 1st postoperative day.

    Time frame: Postoperative day 1

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Mar 2023 to primary completion in Nov 2023, 8 months.

Of 1,207 non-industry interventional studies with no phase under Sleep Initiation and Maintenance Disorders, half reached primary completion within 15 months of starting (the median), counting those still running; a quarter within 6 and three quarters within 35. This study's 8 months is below that.

Counting every sponsor, half of 1,285 studies reached it within 15 months; a quarter within 6 and three quarters within 34.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 21, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
