Brief summary

There are more than twenty factors in the literature defined to effect the spinal anesthesia spread. In patients with a larger hip size and a narrow shoulder size, more cephalad spread of spinal anesthesia induced with a fixed amount of hyperbaric bupivacaine is observed. We hypothesized that the increase in cephalad spread is strongly correlated with the increased hip/shoulder size ratio. Age, weight, height, body mass index, hip size, shoulder size, hip/shoulder size ratio, vertebral column length were recorded for 75 term parturient. The L4-L5 interspace was entered and 2ml 0.5% hyperbaric bupivacaine was given intrathecal in 10 seconds without barbotage. Pearson Correlation Test was performed for the correlation between age, height, weight, body mass index, hip/shoulder size ratio, and vertebral column length

Interventions

2ml 0.5% hyperbaric bupivacaine was injected intrathecally in 10 seconds without barbotage as a single dose from L4-L5 interspace of spinal cord by an anesthesiologist. The dose administered was controlled by the study staff as a standard dose of 2ml according to study protocol. Surgery started when the level of spinal anesthesia reached T6 dermatome
