Comparison of outcomes for intubated patients
| SAPB (n=9) | EPVB (n=15) | P value* | |
| Comparison of outcomes for intubated patients (n=24) | |||
| LOS | 22.9±10.9 | 25.2±6.9 | 0.77 |
| ICU LOS | 12.8±9.2 | 14.4±7.1 | 0.59 |
| Preblock RSBI | 98.1±40.3 | 64.4±41.2 | 0.05 |
| Change in RSBI | 40.8±33.9 | 15.8±33.0 | 0.08 |
| Mortality | 2 (22) | 0 (0) | 0.06 |
Results are presented as mean±SD or n (%) as appropriate.
Change in RSBI is expressed as a difference between preblock and postblock RSBI.
*Where appropriate, the Wilcoxon-Mann-Whitney test and Pearson’s χ2 test p value to compare the means between populations was reported; significant p value <0.05.
EPVB, epidural or paravertebral block; ICU, intensive care unit; LOS, length of stay; RSBI, rapid shallow breathing index; SAPB, serratus anterior plane block.
