Key result
Lumbar epidural anesthesia significantly decreased brachial blood flow (42 vs 66 ml/min, P<0.001) and increased forearm vascular resistance, indicating enhanced vascular tone and sympathetic reactivity.

May enhance forearm vascular tone during epidural anesthesia; hypothesis-generating and should not yet change practice.

Absolute Event Rate: 42% vs 66%
p-value: p=<0.001
Lumbar epidural anesthesia enhances forearm vascular tone and sympathetic reactivity, demonstrating compensatory vascular responses during sensory blockade.
Baron et al. (1988) studied Lumbar epidural anesthesia (n=10). Lumbar epidural anesthesia vs. Before epidural anesthesia was evaluated on Brachial blood flow at T11 sensory blockade (p=<0.001). Lumbar epidural anesthesia significantly decreased brachial blood flow (42 vs 66 ml/min, P<0.001) and increased forearm vascular resistance, indicating enhanced vascular tone and sympathetic reactivity.
