Worldwide, patients experience difficulties accessing elective surgical care. This study examined the perceived health, social, and functional impacts of elective surgical cancellations and postponements in Canada. ⋯ Results highlight the multifaceted perceived impacts of surgical cancellations/postponements. These findings suggest there is a need for improvements in reducing elective surgical cancellations and postponements. Results may also inform the development of targeted interventions to improve patients' health and quality of life while waiting for surgery.

The erector spinae plane (ESP) block is an emerging regional anesthetic technique with significant potential for clinical benefit. Nevertheless, its exact mechanism(s) of action has been much debated. We reviewed the available literature to explore the possible mechanisms of analgesia for the ESP block. ⋯ A systemic effect of local anesthetic is also plausible, but unlikely to be a major contributor to clinical analgesic efficacy. The evidence for significant analgesia due to other proposed mechanisms, such as fascia-mediated analgesia or lymphatic spread, are currently limited and thus remain speculative. Understanding the mechanisms of action could assist clinicians in further investigating and refining ESP block performance, with the ultimate goal of optimizing analgesic efficacy and improving postoperative patient outcomes.
