Comparison of blood pressure measurement using TOF-Cuff® and standard monitoring (MP 30, Philips; Zurich, Switzerland)
| Time point of assessment | TOF-Cuff® | Standard monitoring | P value | |
|---|---|---|---|---|
| Beginning of anesthesia induction | Systolic | 143.0 (130.5–151.0) | 133.0 (117.8–149.3) | 0.1781 |
| MAP | 94.0 (86.0–104.0) | 89.5 (81.8–97.3) | 0.0791 | |
| Diastolic | 63.0 (58.5–70.0) | 74.5 (68.8–85.0) | < 0.0011 | |
| End of anesthesia induction | Systolic | 107.0 (89.8–117.3) | 109.0 (93.8–117.0) | 0.8051 |
| MAP | 72.0 (61.8–84.0) | 76.5 (69.8–80.8) | 0.9411 | |
| Diastolic | 51.5 (41.8–57.3) | 64.0 (54.5–73.5) | < 0.0011 | |
| All | Systolic | 124.6 (± 29.8) | 123.0 (± 29.4) | 0.6162 |
| MAP | 85.5 (± 20.3) | 84.2 (± 16.6) | 0.4882 | |
| diastolic | 56.2 (± 13.5) | 70.7 (± 15.5) | < 0.0012 |
Data displayed as mean (± SD) or median (IQR) in mmHg; all assessments for blood pressure that were based on two measurements are weighted by weight = 0.5
