Randomized trial compares levobupivacaine and ropivacaine for anesthesia in infraumbilical surgeries, suggesting levobupivacaine may be superior.

To compare the efficacy of levobupivacaine and ropivacaine for sensory and motor block in infraumbilical surgery.
Randomized, double-blind trial involving 90 patients assigned to receive either 0.5% levobupivacaine or 0.75% ropivacaine.
Evaluations included onset and duration of sensory and motor block and hemodynamic parameters.
Assessments were made at various time points to measure effectiveness and side effects.
Levobupivacaine showed faster onset of sensory block at 5.9 minutes (Group L) vs. 8.3 minutes (Group R).
Duration of sensory block was longer in Group L (268 minutes) compared to Group R (160 minutes).
Levobupivacaine also led to a longer motor block duration (230 minutes) versus ropivacaine (136 minutes), p < 0.0001.
