Clinical Characteristics of Spinal Levobupivacaine: Hyperbaric Compared with Isobaric Solution

Figure 2

Sensory block levels at 5 and 15 minutes after spinal block, and peak levels of sensory block in patients receiving isobaric (blue bars) or hyperbaric levobupivacaine (red bars). Hyperbaric levobupivacaine reached higher sensory block levels at all periods of time (^∗𝑃=0.011, ^†𝑃=0.027, and ^‡𝑃=0.040, resp.). More patients in hyperbaric group reached T10 or higher at 5 minutes, T4 or higher at 15 minutes, and higher peak levels of sensory block than in isobaric group (^∗𝑃=0.011, ^†𝑃=0.005, and ^‡𝑃=0.005, resp.).
