Description of intervention(s) / exposure
For the female adult patients who receive transvaginal oocyte retrieval, we use propofol target-controlled infusion as sedation. The initial TCI effect-site concentrations of propofol (Ceprop) was set at 4.0 microgram/ml and Ceprop was adjusted in steps of 0.2 microgram/ml to keep Entropy value at between 40 and 60. The propofol infusion begin before the insertion of the ultrasound probe and stopped when the probe was removed from the vagina. Later, the patients were assigned to two groups based on the result of Pittsburgh Sleep Quality Index. Patients with total score less than or equal to 5 was included in the group of good sleep quality and total score greater than 5 was assigned to the group of poor sleep quality. The data collected will be analyzed to decide whether poor sleep quality results in low target effect-site propofol concentration required for adequate sedation during transvaginal oocyte retrieval or not.

Outcomes
Primary outcome [1] 295052 0
Relationship between sleep quality measured by using Pittsburgh Sleep Quality Index and the TCI effect-site concentrations of propofol required for loss of consciousness (loss of response to verbal commands) recorded by TCI device.
Timepoint [1] 295052 0
Pittsburgh Sleep Quality questionnaire completed by the patients before the procedure and target effect-site propofol concentration recorded at the time of anesthesia induction
Secondary outcome [1] 313702 0
Total propofol comsuption recorded by a TCI device
Timepoint [1] 313702 0
At the end of the transvaginal oocyte retrieval
Secondary outcome [2] 313703 0
Total sedation time recorded by a timer. Sedation begins when the patients lose response to verbal commands and ends when the patient could react to verbal commands.
Timepoint [2] 313703 0
At the end of the transvaginal oocyte retrieval
Secondary outcome [3] 313704 0
Post-procedure complication including nausea, vomiting,and pruritus observed by nurse in post anesthesia care unit. A phone interview will be performed after the patient goes home.
Timepoint [3] 313704 0
within one week after the intervention
Secondary outcome [4] 314674 0
Emergence time recorded by a timer. Emergence time was defined as the time required for the patient to react to verbal commands after TCI was stopped.
Timepoint [4] 314674 0
At the end of the transvaginal oocyte retrieval

Summary
Brief summary
The majority of oocyte retrievals are currently performed through a transvaginal approach with ultrasonographic guidance. When receiving this procedure, most patients will suffered from painful sensation and move their legs during insertion of transvaginal ultrasound probe and aspiration needle. We anesthesiologists provide proper sedation and analgesics in order to keep patient’s steady position so that obstetricians can perform oocyte retrieval smoothly. Target controlled infusion (TCI) is considered the best way to maintain perioperative sedation since the device enable the drug concentration
in the blood or plasma, or at the effect site, to be controlled continuously.
According to past animal studies, sleep deprivation potentiated the ability of certain inhalation agent (isoflurane) and intravenous anesthetics (propofol) to produce loss of righting reflex in deprived rats. Besides, recent studies indicated that propofol may induces sedation by increasing firing of GABAergic neurons in the VLPO (ventrolateral preoptic nucleus) which was also known as a key area in non-rapid eye movement (NREM) sleep-promoting pathway. However, the presence of regulatory interactions between anesthesia and sleep was not confirmed currently.
Thus, we design this study trying to figure out the relationship between sleep quality and target effect-site propofol concentration of TCI during a patient receiving transvaginal oocyte retrieval. Pittsburgh Sleep Quality Index was used to evaluate the patients’ sleep quality and the questionnaire will be completed before the procedure. During oocyte retrieval, Entropy monitoring will be set to assess anesthetic depth and the predicted Ceprop as well as time required for loss of consciouness (loss of response to verbal commands), total sedation time, propofol comsuption, and emergence time will be recorded. After the procedure was completed, the patients were assigned to two groups based on the result of Pittsburgh Sleep Quality Index. Patients with total score less than or equal to 5 was included in the group of good sleep quality and total score greater than 5 was assigned to the group of poor sleep quality. The data collected will be analyzed to decide whether poor sleep quality results in low target effect-site propofol concentration required for adequate sedation during transvaginal oocyte retrieval or not.
