WebPatients randomly received either 0.5% ropivacaine (n = 25) or 0.5% bupivacaine (n = 25). The anesthetic volume was decided according to Dixon's up-and-down method, starting from 12 mL and being equally divided among the three elicited twitches. WebJul 1, 2007 · THE up-and-down method for estimating the 50 per cent response point of quantal data was originally devised for testing the sensitivity of explosives.

Advances in and Limitations of Up-and-down Methodology:
WebThe up-and-down test method strategy is illustrated in Table 1 for the explosives sensitivity example. The first specimen is tested at a drop height chosen as close as possible to the median critical height. If Specimen 1 does not explode, Specimen 2 is subsequently tested with the original drop height increased by a fixed increment a WebMethods: Sixty patients with esophageal cancer were randomized to receive ESPB using 28 mL of 0.5% ropivacaine, with 2 mL of normal saline (group R) or 0.5 µg/kg … sims 4 resource catalog
