The review emphasizes the need for randomized controlled trials to confirm the safety benefits of multidisciplinary perioperative ultrasound protocols in anesthesia.
Perioperative ultrasound protocols should not yet change anesthesia practice; leaves open safety benefits pending RCTs.
Since most of the articles included in this review are observational studies with inherent design concerns, there is an urgent requirement for randomized controlled trials in this area. As anesthesiologists become more comfortable and knowledgeable in ultrasound applied to the perioperative support, emergence of protocols with multidisciplinary ultrasound exploration is expected to allow an improvement in perioperative safety.
