Ultrasound measurement of traumatic scar and skin thickness: a scoping review of evidence across the translational pipeline of research-to-practice.

OBJECTIVES: To identify the ultrasound methods used in the literature to measure traumatic scar thickness, and map gaps in the translation of these methods using evidence across the research-to-practice pipeline. DESIGN: Scoping review. DATA SOURCES: Electronic database searches of Ovid MEDLINE, Embase, Cumulative Index of Nursing and Allied Health Literature and Web of Science. Grey literature searches were conducted in Google. Searches were conducted from inception (date last searched 27 May 2022). DATA EXTRACTION: Records using brightness mode (B-mode) ultrasound to measure scar and skin thickness across the research-to-practice pipeline of evidence were included. Data were extracted from included records pertaining to: methods used; reliability and measurement error; clinical, health service, implementation and feasibility outcomes; factors influencing measurement methods; strengths and limitations; and use of measurement guidelines and/or frameworks. RESULTS: Of the 9309 records identified, 118 were analysed (n=82 articles, n=36 abstracts) encompassing 5213 participants. Reporting of methods used was poor. B-mode, including high-frequency (ie, >20 MHz) ultrasound was the most common type of ultrasound used (n=72 records; 61% of records), and measurement of the combined epidermal and dermal thickness (n=28; 24%) was more commonly measured than the epidermis or dermis alone (n=7, 6%). Reliability of ultrasound measurement was poorly reported (n=14; 12%). The scar characteristics most commonly reported to be measured were epidermal oedema, dermal fibrosis and hair follicle density. Most records analysed (n=115; 97%) pertained to the early stages of the research-to-practice pipeline, as part of research initiatives. CONCLUSIONS: The lack of evaluation of measurement initiatives in routine clinical practice was identified as an evidence gap. Diverse methods used in the literature identified the need for greater standardisation of ultrasound thickness measurements. Findings have been used to develop nine methodological considerations for practitioners to guide methods and reporting.

Systematic Review of Morbidity and Mortality Meeting Standardization: Does It Lead to Improved Professional Development, System Improvements, Clinician Engagement, and Enhanced Patient Safety Culture?

OBJECTIVES: This systematic review sought to better understand the effect of standardized Morbidity and Mortality meetings (M&Ms) on learning, system improvement, clinician engagement, and patient safety culture. METHODS: Three electronic databases were searched using a range of text words, synonyms, and subject headings to identify the major concepts of M&M meetings. Articles published between October 2012 (the end date of an earlier review) and February 2021 were assessed against the inclusion criteria, and thematic synthesis was conducted on the included studies. RESULTS: After abstract and full-text review in Covidence, from 824 studies identified, 16 met the eligibility criteria. Studies were mostly surveys (n = 13) and evaluated effectiveness primarily from the perspectives of M&M chairs and participants, rather than assessment of objective improvement in patient outcomes. The most prevalent themes relating to the standardization of M&M processes were case selection (n = 15) and administration (n = 12). The objectives of quality improvement and education were equally prevalent (12 studies each), but several studies reported that these 2 objectives as conflicting rather than complementary. Clinician engagement, patient safety culture, and organizational governance and leadership were identified as facilitators of effective M&Ms. CONCLUSIONS: There is insufficient evidence to guide best practice in M&Ms, but standardized structures and processes implemented with organizational leadership and administrative support are associated with M&Ms that address objectives related to learning and system improvement. Standardization of the structures and processes of M&Ms is perceived differently depending on participants' role and discipline, and clinician engagement is critical to support a culture of safety and quality improvement.

NK1 receptor antagonists versus other antiemetics in the prevention of postoperative nausea and vomiting following laparoscopic surgical procedures: a systematic review and meta-analysis.

A systematic electronic search of MEDLINE, EMBASE, and CINAHL databases aimed at comparing neurokinin-1 receptor antagonists with other antiemetics in their prevention of postoperative nausea and vomiting in adult patients undergoing laparoscopic surgery identified seven randomized controlled trials for review and meta-analysis. Preoperative aprepitant 80 mg was found to reduce nausea (RR: 0.56, 95% CI: 0.41-0.75, I2 = 0%, P = 0.89) and vomiting (RR: 0.20, 95% CI: 0.05-0.77, I2 = 0%, P = 0.96) and resulted in complete response (RR: 1.61 (1.25-2.08), I2 = 0%, P = 0.70) within the first 2 hours following surgery as well as vomiting in 2-24 hours (RR: 0.09, 95% CI: 0.02-0.36, I2 = 0%; P = 0.81) when compared to placebo or no antiemetic therapy. Preoperative aprepitant 80 mg has a superior overall effect compared to placebo or other antiemetics in the first two hours postoperatively, and thereafter reduces the risk of vomiting alone in the first 24 hours following laparoscopic surgeries.

Perioperative Presentations of Kounis Syndrome: A Systematic Literature Review.

Kounis syndrome commonly is described as a complex multisystem phenomenon mainly affecting coronary arteries, resulting in coronary vasospasm in the context of an allergic manifestation. This article reviews the literature regarding perioperative presentations of the syndrome. A systematic search in MEDLINE and Embase databases was performed for case reports through June 16, 2021, on Kounis syndrome triggered by medications administered in the perioperative setting. The authors' search resulted in 35 perioperative reports of Kounis syndrome, with the majority of the cases occurring in men between 40 and 80 years of age, manifesting within 20 minutes following the administration of the suspected trigger. Chest pain and ischemic changes on the electrocardiograph were the most frequent presentations, while intravenous antibiotics and neuromuscular blocking agents were the most common triggers. In most instances, the patients had a good recovery following the event. Coronary vasospasm is often less frequently recognized as a form of allergic manifestation in the perioperative setting. Many potential triggers, such as antibiotics and neuromuscular blocking agents, are routinely administered during surgery. Awareness of this condition, early diagnosis, and effective management of this condition can lead to good outcomes.
