Regional haemodynamic variables and perfusion index in the evaluation of sciatic nerve block: a prospective observational trial.

ABSTRACT:

Objective

We determined whether regional haemodynamics and perfusion index (PI) could be reliable indicators of a successful sciatic nerve block (SNB).

Design

Prospective observational trial.

Setting

A tertiary teaching hospital in China from April 2020 to August 2020.

Participants

We assessed 79 patients for eligibility to participate in this study. Nine patients were excluded for not meeting our inclusion criteria, and three patients were excluded due to missing measurements at all time points.

Interventions

The patients underwent SNB. Pulsed-wave Doppler and PI measurements were performed.

Primary and secondary outcome measures

The primary outcome measure was the diagnostic power of regional haemodynamic change and PI to predict successful SNB.
