Abstract: Purpose: The purpose of our study was to evaluate effective ischemia and
its associated complications using the limb occlusion pressure technique
versus standard pneumatic ischemia technique.
Design: Single-centered randomized, controlled clinical trial.
Methods: One hundred sixty participants were randomized into two
equal and parallel groups: (1) intervention group?LOP technique,
and (2) control group?standard pneumatic ischemia technique.
Findings: Anesthetic incidences (need to administer analgesics for pain
and/or hypnotics for anxiety) were similar in both groups. Statistically
significant differences were observed for pain, hyperemia, and hospitalization,
with higher values in the control group. Patients in the intervention
group had, at 95% confidence, a 2.9 times greater chance of having
optimal ischemia (assessed as 9 on the analog scale) than patients in the
control group (odds ratio, 2.9; 95% confidence interval, 1.4 to 6.1).
Conclusions: Intervention group patients had lower indexes of hyperemia,
pain, and hospital stay.
