Effects of conventional preoperative patient management (control) and modified ERAS® protocol (MEP) on intraoperative anesthetic management in patients for elective gastrectomy
| Control group | MEP group | P value | |
|---|---|---|---|
| Sex (men/women) | 15/35 | 21/29 | P = 0.21 |
| Age (years) | 66 ± 10 | 62 ± 12 | 0.07 |
| Anesthetic method (inhalation/intravenous) | 18/32 | 13/37 | 0.28 |
| Type of surgery (laparotomy/endoscopy) | 22/28 | 21/29 | 0.16 |
| Epidural anesthesia (no. of patients) | 50 | 50 | |
| BMI (kg/cm2) | 22.1 ± 6.9 | 23.0 ± 6.0 | 0.09 |
| ASAPS (I/II) | 21/29 | 20/30 | 0.84 |
| Vomiting due to anesthesia (no. of patients) | 0 | 0 | |
| Surgical time (min) | 169 ± 61 | 188 ± 39 | 0.07 |
| Bleeding (ml) | 149 ± 195 | 171 ± 146 | 0.53 |
| Volume of infusion (ml/kg/h) | 9.1 ± 2.9 | 8.4 ± 2.5 | 0.18 |
| Urine volume (ml/kg/h) | 0.9 ± 0.6 | 1.3 ± 0.8 | 0.03 |
| Use of vasopressor (times) | 0.5 ± 0.6 | 0.4 ± 0.4 | 0.24 |
Statistical analysis: age and BMI were analyzed by unpaired t-test (significance level with two-sided, P = 0.05), and sex, ASAPS, and type of surgery were analyzed by chi-square test (significance level with two-sided, P = 0.05)
