Anesthesia type | Era 1 | Era 2 | Era 3 | P value |
DS, n (%) | 41 (65.1) | 73 (83.0) | 61 (70.1) | 0.033 |
GA, n (%) | 22 (34.9) | 15 (17.0) | 26 (29.9) | 0.033 |
DS only SpO2 nadir, | 4.5 (98.0) | 3.0 (99.0)a | 4.0 (96.0) | < 0.001 |
There was a significantly lower utilization of GA in era 2 compared to era 1 (P = 0.012) that persisted as a trend only between eras 2 and 3 after Bonferroni correction (P = 0.045). There was a significantly lower median SpO2 nadir in era 3 compared to era 2 (aP < 0.001) that was a trend between eras 1 and 2 after Bonferroni correction (P = 0.028). DS: Deep sedation; GA: General anesthesia.
