MAC Bipsectral Index Below 50 for Chronic Opioid User
The Effect of Chronic Opioid Use on Minimum Alveolar Concentration of Sevoflurane for Maintaining Bispectral(BIS) Index Below 50 ; Prospective, Blind Study
研究概览
详细说明
- Patients selection in elective surgery which need general anesthesia.
- MAC BIS50 data was collected in each patients (by blinded investigator)
- The data collection will be continued for enough sample size for using Dixon Up Down Method Analysis
- After Data collection, MAC BIS below 50 will be analyzed in both groups ( Chronic opioid users versus opioid naive patients)

实验性的:Chronic Opioid User
The patients (ASA class I-III) who receive elective surgery s aging between 41 and 69 and signed in informed consent to participate in this trial voluntarily. The Patients who use opioid medication daily and regularly immediately before the day of surgery for more than four weeks. The minimum criteria for opioid dose in the intervention goup is oral morphine 20mg per day: Morphine Equivalent Daily Dose(MEDD) |

无干预:Opioid Naive patient
The patients (ASA class I-III) who receive elective surgery aging between 41 and 69 and signed in informed consent to participate in this trial voluntarily. The patients who do not use opioid medications immediately before the day of surgery for four weeks. |

措施说明 |
大体时间 |
|---|---|---|
|
Minimum Alveolar Concentration below BIS 50 in Sevoflurane; percentage (eg: 1.2%)
大体时间:15 minutes after pre-set of the concentration of sevoflurane
|
Dixon's up down method is applied in this study.
So pre-set concentration of sevoflurane will be used in each group.
