摘要

Purpose

Regional anesthesia (RA) is often perceived to be more environmentally sustainable than alternative forms of anesthesia. Nevertheless, the principles of sustainable RA remain ill-defined in the presence of variability of resource utilization within RA practice. Many infection prevention practices are based on low-level evidence, and recommendations vary internationally. We sought to conduct an evidence review and Delphi consensus study to provide guidance on aspects that lack high-quality evidence in RA practice to reconcile responsible resource stewardship and infection prevention in RA.

Methods

We conducted a three-round modified Delphi process. After distributing an initial free-text questionnaire to all collaborators, we created structured questions, followed by two rounds of anonymized voting. We defined strong consensus as ≥ 75% agreement and weak consensus as ≥ 50% but < 75% agreement.

Results

Forty-six experts agreed to take part in the study and 36 (78%) completed all the voting rounds. Regional anesthesia practice parameters with strong consensus included hand hygiene using alcohol scrub rather than soap and water, sterile gowns being unnecessary for single-injection RA techniques, only minimal equipment in the premade packs, and goal-directed use of sedation and supplemental oxygen.

Discussion

We obtained consensus on the safe and environmentally responsible practice of RA for both single-injection and indwelling catheter techniques and identified areas of research focus. While more robust evidence is being generated, clinicians may use these findings as a guide to infection prevention and environmental sustainability in their anesthesia practice.
