Outcomes by type of serial change in cerebral rSO2.
| Type 1: Increasing type |
Type 2: Non-increasing type |
Crude OR (95% CI) |
p Value | Adjusted OR* (95% CI) |
p Value | |
|---|---|---|---|---|---|---|
| Prehospital ROSC, % (n/N) | 27.5 (11/40) | 4.26 (2/47) | 8.53 (1.76–41.32) | 0.008 | 5.67 (1.04–30.96) | 0.045 |
| Alive at hospital admission, % (n/N) | 42.5 (17/40) | 12.8 (6/41) | 5.05 (1.75–14.60) | 0.003 | 3.56 (1.11–11.43) | 0.033 |
| 1-Month survival, % (n/N) | 12.5 (5/40) | 2.1 (1/47) | 6.57 (0.73–58.81) | 0.092 | 3.21 (0.32–32.72) | 0.324 |
| CPC 1 or 2, % (n/N) | 7.5 (3/40) | 0 (0/47) | N/A | N/A | N/A | N/A |
ORs were calculated for Increasing type vs. Non-increasing type.
CPR, cardiopulmonary resuscitation; CPC, Cerebral Performance Category; OR, odds ratio; CI, confidence interval; ROSC, return of spontaneous circulation; rSO2, regional saturation of oxygen.
