Clinical characteristics of patients and operation/anesthesia duration (n=32)
| Characteristics | TEAS | C | P-value* |
|---|---|---|---|
| Age (years) | 71±5 | 73±4 | 0.058 |
| Gender (male/female), n | 15/17 | 18/14 | 0.453 |
| BMI (kg/m2) | 26.6±2.5 | 26.5±2.2 | 0.864 |
| ASA (physical status I/II), n | 19/13 | 17/15 | 0.614 |
| Operation duration (minutes) | 136±8 | 134±9 | 0.735 |
| Anesthesia duration (minutes) | 171±8 | 167±11 | 0.053 |
| Infarct topography | 0.777 | ||
| Basal ganglia (n) | 26 | 28 | |
| Corona radiata (n) | 2 | 1 | |
| Thalamus (n) | 4 | 3 |
Notes: Data are expressed as mean ± SD. Independent sample t-test was used to compare age, operation duration, anesthesia duration, and BMI between groups. Chi-squared test was used to compare gender and ASA physical status between groups. The significance level was set at P<0.05.
