Key result
Obesity (BMI ≥30) was associated with a slightly lower success rate of supraclavicular block compared to non-obese patients (94.3% vs 97.3%, P<0.01), with no difference in acute complications.
Why the study?
Does obesity affect the success rate and acute complications of supraclavicular block?

Comparison
Supraclavicular block in obese patients (BMI ≥30) vs Supraclavicular block in non-obese patients

Supports supraclavicular block feasibility in obesity with high success and no added complications; leaves open prospective evaluation of technique refinements.

Does obesity affect the success rate and acute complications of supraclavicular block?
Absolute Event Rate: 94.3% vs 97.3%
p-value: p=<0.01
Supraclavicular block is highly successful in both obese and non-obese populations, with only a slight decrease in success rate and increased difficulty in obese patients, and no difference in acute complications.
Franco et al. (2006) conducted a cohort in Patients requiring regional anesthesia (n=2,020). Obesity (BMI ≥30) vs. Non-obese patients was evaluated on Overall success rate of supraclavicular block (p=<0.01). Obesity (BMI ≥30) was associated with a slightly lower success rate of supraclavicular block compared to non-obese patients (94.3% vs 97.3%, P<0.01), with no difference in acute complications.
