2. Fig 1
Maximum upper level of sensory block to pin prick in the three groups of patients. Each symbol represents one patient and the solid horizontal bars indicate the median upper level for that particular group. The upper level of the patient in the ropivacaine group withdrawn due to technical failure was L4 and is not represented in the graph.

Cephalad extent of sensory block to pin prick (median dermatome) against time in three groups of patients receiving spinal anaesthesia with 3 ml of either bupivacaine, levobupivacaine, or ropivacaine at a concentration of 5 mg ml−1 (with glucose 30 mg ml−1).

Percentage of patients with Bromage scores (using a modified Bromage scale), 2 or 3 in each group plotted against time for three groups of patients receiving spinal anaesthesia with 3 ml of either bupivacaine, levobupivacaine, or ropivacaine at a concentration of 5 mg ml−1 (with glucose 30 mg ml−1).
