What researchers measure

Primary outcomes

  1. Surgeon and patient satisfaction

    It was evaluated with an absolute numerical subjective scale from 1 to 7, where a score of 1 means total dissatisfaction, and 7 complete satisfaction. Scores were evaluated 30 minutes after surgery begun and at the end of the procedure. Results are presented in median and interquartile ranges.

    Time frame: Intraoperative

Secondary outcomes

  1. Heart rate

    Beats per minute (bpm)

    Time frame: Intraoperative

  2. Mean arterial pressure

    Millimeters of mercury (mmHg)

    Time frame: Intraoperative

  3. Hemoglobin oxygen saturation

    Oxygen saturation (%)

    Time frame: Intraoperative

  4. Surgery duration

    Minutes

    Time frame: Intraoperative

Other outcomes

  1. Hypotension

    Systolic blood pressure below 90 mmHg

    Time frame: Intraoperative

  2. Respiratory depression

    Decreased respiratory rate below 10 rpm and desaturation, situation that required intubation

    Time frame: Intraoperative

  3. Oxygen desaturation

    Hemoglobin oxygen saturation below 90%

    Time frame: Intraoperative

  4. Internation

    Inpatient treatment

    Time frame: Intraoperative

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 Jan 17, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
