bariatric surgery, deep neuromuscular blockade
Brief summary
Find out the deciding factor(total body weight, corrected body weight, ideal body weight, fat-free mass, body mass index, skeletal muscle mass, body fat) of neuromuscular blocker dose for deep neuromuscular blockade in bariatric surgery.
Detailed description
Before the surgery, total body weight, corrected body weight, ideal body weight, fat-free mass, body mass index were measured by height and weight and skeletal muscle mass and body fat were measured by Bioelectrical impedance analysis (InbodyH20B). Find the highest correlation between the 8 factors (total body weight, corrected body weight, ideal body weight, fat-free mass, body mass index, skeletal muscle mass, body fat) and the amount of rocuronium administered to deep neuromuscular blockade in bariatric surgery.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| the highest correlation coefficient | preoperative 1 days to postoperative 1 days | the relationship of rocuronium for deep neuromuscular blockade in bariatric surgery and 8 factors (corrected body weight, ideal body weight, lean body weight, fat-free mass, body mass index, skeletal muscle mass, body fat) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| onset time of rocuronium | preoperative 1 days to postoperative 1 days | time from injection of rocuronium 0.6 mg/kg(TBW) to TOF ratio is less than 0.05 |
| time to deep neuromuscular blockade | preoperative 1 days to postoperative 1 days | time from injection of rocuronium 0.6 mg/kg(TBW) to PTC 1 |
| Recovery time | preoperative 1 days to postoperative 1 days | time from sugammadex injection to TOF ratio \> 0.9 |
