Outcomes

Primary Outcome Measures

Peak pain score assessed by numeric rating scale (NRS) in post-anesthesia care unit (PACU)
Patients are asked to rate their pain according to the numeric rating scale (NRS, 0=no pain to 10= extreme pain imaginable) every 10 min after the PACU admission. Peak pain score is the peak NRS during PACU stay. Higher NRS represents a worse outcome.

Secondary Outcome Measures

Intraoperative remifentanil consumption rate
The amount of remifentanil consumption during the operation is calculated by following equation: Total remifentanil consumption (mcg) / body weight of the patients (kg)/ duration of anesthesia (min)
Postoperative adverse events
Check the postoperative nausea and vomiting, dizziness, desaturation, urinary retention, itching sensation and bradycardia
Remnant sedation degree
Remnant sedation is evaluated by Riker Sedation-Agitation (RSA) Scale every 10 minutes after the PACU admission. unarousable, minimal or no response to noxious stimuli, does not communicate of follow commands very sedate, arouse to physical stimuli but does not communicate or follow command, may move spontaneously sedate, difficult to arouse but awakens to verbal stimuli or gentle shaking, follows simple commands but drifts off again Calm and cooperative, calm and follows commands agitated, anxious or physically agitated and calms to verbal instructions very agitated, requiring restraint and frequent verbal reminding of limits, biting endotracheal tubes dangerous agitation, pulling at tracheal tube, trying to remove catheters or striking at staff RSA scale 4 means normal. If the RSA <4, it means the patients are sedated. If the RSA >5, it means the patients are agitated.
Pain score assessed by numeric rating scale (NRS) 1 day after the operation
Patients are asked to rate their pain according to the numeric rating scale (NRS, 0=no pain to 10= extreme pain imaginable) 1 day after the operation. Higher NRS represents a worse outcome.
Total analgesic consumption after PACU discharge
Check the analgesic consumption after PACU discharge including oral, intramuscular and intravenous administration.
Intraoperative propofol consumption
The amount of propofol consumption during the operation
Intraoperative mean SPI
Check the SPI value throughout the operation using the vital recorder program.

5. Study Description

Brief Summary
In this study, the investigators measure a pupil size every 5 minutes during the operation in patients undergoing laparoscopic cholecystectomy under general anesthesia. The investigators would compare the postoperative pain intensity between the group adjusted the anesthetic drug concentration based on the changes of the pupil (Pupil group) and the group based on the changes of a surgical pleth index (SPI group).

Arm Title
SPI group
Arm Type
Active Comparator
Arm Description
In this group, intraoperative analgesia is performed using SPI guided anesthesia
Intervention Type
Procedure
Intervention Name(s)
Pupilometer guided anesthesia
Intervention Description
At least 10 min after anesthesia induction by target-controlled infusion of propofol and remifentanil, baseline values for pupillary diameter is recorded before any surgical procedure. During the operation, propofol effect-site target concentration (Ce) is adjusted to maintain the bispectral index (BIS) value between 40 and 60. Remifentanil Ce is adapted every 5 min based on the changes of pupillary diameter. If the pupillary diameter is increased by more than 30% compared to baseline value, remifentanil concentration is increased by 0.5 ng/ml. If the pupillary diameter is maintained between 5 and 30 % change compared with baseline, remifentanil is not modified. In a case of pupillary diameter is decreased less than 5 % change of baseline, remifentanil concentration is decreased by 0.5 ng/ml.
Intervention Type
Procedure
Intervention Name(s)
SPI guided anesthesia
Intervention Description
During the operation, SPI value should be maintained between 20 and 50 by changing the infusion rate of remifentanil. Even if the SPI is maintained within the target range, the remifentanil infusion rate is increased by 0.5 ng/ml in a case of the SPI value suddenly arises by more than 10.
