Table 2 Time to onset/offset variables. Data are expressed as mean ± SD. Tsb: time to onset of sensory block, Tmb: time to onset of motor block, Trs: time to readiness for surgery, Tsbmax: time to maximum level of sensory block, Trd: time to regression of two dermatomes; TS1: time to regression of sensory block to S1, Tea time to regression of both motor and sensory blocks; Trmb: time to regression of motor block; Tua: time to unassisted ambulation; Tra: time to first administration of rescue analgesia; Tuv: time to first spontaneous urinary voiding; Thd: time to home discharge
