Comparison of 2 concentrations of levobupivacaine in postoperative patient-controlled analgesia

peer reviewedBoth groups were similar with regard to demographics, upper level of sensory blockade (T8), and visual analog scale pain scores at rest and after coughing, as well as levobupivacaine and subcutaneous rescue morphine consumption. Motor blockade in the lower limbs was very low in both groups. Arterial blood pressure was slightly lower in the 5 mg/mL group during the first 24 hours ( P = 0.052). Five patients in the 1.5 mg/mL and 7 in the 5 mg/mL group had postoperative nausea and vomiting ( P = 0.43). No other side effects were recorded, and all of the patients were satisfied
