Study summary

Sleep is important in maintaining the physiological function of the human body. Recently several studies have reported that preoperative sleep quality is associated with postoperative emergence delirium (ED) The ED is a common in pediatric patients undergoing general anesthesia with sevoflurane, but studies on the association of sleep quality have been rare. The investigators, therefore, aimed to investigate the relationship between postoperative delirium and pre and postoperative sleep quality in pediatric patients receiving strabismus surgery through this study

Read the detailed description

This study aimed on pediatric patients aged 4-12 years, undergoing elective strabismus surgery. Informed consent was obtained from both parents and children on the day of pre-anesthetic evaluation visit. The child and his or her parents were questioned on preoperative patient's sleep quality based on Pittsburg Sleep Quality Index (PSQI). Surgery was performed under the same anesthesia as usual. After the operation, extubation was performed and patient was moved to post anesthesia recovery room (PACU). During the stay in PACU, one investigator measured degree of ED by Watcha and PAED (Post anesthesia emergence delirium ) scale to minimize bias. One day after the surgery, the investigator mede a phone call to the parents of the patient to obtain information for postoperative PSQI.

What researchers measure

Primary outcomes

  1. Preoperative Pittsburgh Sleep Quality Index(PSQI)

    1. Add the Seven component score. Score range : 0\~27 2. A total score of "5" or greater is indicative of poor sleep quality.

    Time frame: 1. Before the surgery ( Within a week before the surgery)

  2. Watcha scale (For emergence delirium)

    1. Measure the score of most appropriate state of condition. There are four conditions. Score range : 1\~4 2. The score of "3" or greater is indicative of emergence delirium

    Time frame: 20 min after awakening ( In the post anesthesia recovery room)

  3. Pediatric anesthesia emergence delirium scale (PAED) scale

    1. Add the five component score. Score range : 0\~20 2. A total score of "10" or greater is indicative of emergence delirium.

    Time frame: 20 min after awakening ( In the post anesthesia recovery room)

  4. Postoperative Pittsburgh Sleep Quality Index(PSQI)

    1. Add the Seven component score. Score range : 0\~27 2. A total score of "5" or greater is indicative of poor sleep quality.

    Time frame: 1 day after the surgery ( < 24 hours )

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 May 2017 to primary completion in Sep 2017, 4 months.

Of 181 non-industry observational studies under Emergence Delirium, half reached primary completion within 21 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 43. This study's 4 months is below that.

Counting every sponsor, half of 181 studies reached it within 21 months; a quarter within 10 and three quarters within 43.

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 Nov 7, 2017, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
