Psychosocial Interventions at the End-of-Life: A Scoping Review.

BACKGROUND: The integration of holistic and effective end-of-life (EOL) care into cancer management has increasingly become a recognized field. People living with terminal cancer and their caregivers face a unique set of emotional, spiritual, and social stressors, which may be managed by psychosocial interventions. OBJECTIVES: This study aimed to explore the types and characteristics of psychosocial interventions at the EOL for adult cancer patients and their caregivers and to identify gaps in the current literature. METHODS: A systematic search was conducted through MEDLINE (Ovid) and CINAHL from January 1, 2011, to January 31, 2021, retrieving 2453 results. A final 15 articles fulfilled the inclusion criteria, reviewed by 2 independent reviewers. Ten percent of the original articles were cross-checked against study eligibility at every stage by 2 experienced researchers. RESULTS: Most interventions reported were psychotherapies, with a predominance of meaning or legacy-related psychotherapies. Most interventions were brief, with significant caregiver involvement. Most studies were conducted in high-income, English-speaking populations. CONCLUSION: There is robust, although heterogeneous, literature on a range of psychosocial interventions at the EOL. However, inconsistencies in the terminology used surrounding EOL and means of outcome assessment made the comparison of interventions challenging. IMPLICATION FOR PRACTICE: Future studies will benefit from increased standardization of study design, EOL terminology, and outcome assessment to allow for a better comparison of intervention efficacy. There is a need for increased research in psychosocial interventions among middle- to low-income populations exploring social aspects, intimacy, and the impact of COVID-19.

The use of video laryngoscopy outside the operating room: A systematic review.

This study aimed to describe how video laryngoscopy is used outside the operating room within the hospital setting. Specifically, we aimed to summarise the evidence for the use of video laryngoscopy outside the operating room, and detail how it appears in current clinical practice guidelines. A literature search was conducted across two databases (MEDLINE and Embase), and all articles underwent screening for relevance to our aims and pre-determined exclusion criteria. Our results include 14 clinical practice guidelines, 12 interventional studies, 38 observational studies. Our results show that video laryngoscopy is likely to improve glottic view and decrease the incidence of oesophageal intubations; however, it remains unclear as to how this contributes to first-pass success, overall intubation success and clinical outcomes such as mortality outside the operating room. Furthermore, our results indicate that the appearance of video laryngoscopy in clinical practice guidelines has increased in recent years, and particularly through the COVID-19 pandemic. Current COVID-19 airway management guidelines unanimously introduce video laryngoscopy as a first-line (rather than rescue) device.

Emergency Front-of-Neck Airway Rescue Via the Cricothyroid Membrane: A High-Resolution Computed Tomography Study of Airway Anatomy in Adults.

BACKGROUND: Emergency front-of-neck airway rescue is recommended in a can't intubate, can't oxygenate clinical scenario. Cannula cricothyroidotomy has been reported as having a high failure rate. Our primary aim was to estimate the angle of the trachea in relation to the horizontal axis in a simulated emergency front-of-neck airway rescue position. Our secondary aims were to estimate the optimal cannula angle of approach and evaluate the anatomical relationship of the cricothyroid membrane (CTM) to adjacent structures. We also assessed whether the CTM lies above or below the neck midpoint, a point equidistant from the suprasternal notch (SSN), and the chin surface landmarks. All measurements were compared between the male and female subjects. METHODS: Subjects having elective computed tomography of their thorax were consented to have extension of the computed tomography to include their neck. A preliminary radiation dose and risk assessment deemed the additional radiation to be of very low risk (level IIa). Subjects were positioned supinely on the computed tomography table. Standard neck extension was achieved by placing a pillow under the scapulae and a rolled towel under the neck to simulate emergency front-of-neck airway rescue positioning. RESULTS: Fifty-two subjects were included in this study: 31 men and 21 women. The mean angle of the trachea in relation to the horizontal axis was 25.5° (95% confidence interval [CI], 21.8-29.1) in men and 14.0° (95% CI, 11.5-16.5) in women. The mean minimum angles required for hypothetical cannula cricothyroidotomy for men and women were 55.2° (95% CI, 51.8-58.7) and 50.5° (95% CI, 45.4-55.6), respectively. The CTM was located lower in the neck in men compared to women. The CTM was located below the neck midpoint in 30 of 30 (100%) male subjects and 11 of 20 (55%) female subjects (P < .001). CONCLUSIONS: The trachea angulates posteriorly in a simulated emergency front-of-neck airway rescue position in supine subjects and to a greater degree in men compared to women (P < .001). The minimum angle required for hypothetical cannula cricothyroidotomy was >45° in the majority (75%) of subjects studied. A steeper cannula angle of approach may be more reliable and warrants further clinical study. If airway anatomy is indistinct and performing a vertical scalpel cricothyroidotomy, consideration should be given to performing this incision lower in the neck in men compared to women.

Pharmacological and non-surgical renal protective strategies for cardiac surgery patients undergoing cardiopulmonary bypass: a systematic review.

BACKGROUND: Post-operative acute kidney injury after cardiopulmonary bypass (AKI-CPB) for cardiac surgery is a frequent complication. It may require renal replacement therapy (RRT), which is associated with an increased morbidity and mortality. This review explores the efficacy of proposed pharmacological and non-surgical renal protective strategies. METHODS: A comprehensive literature search was done using Ovid MEDLINE, Embase and Scopus databases. Keywords included were cardiopulmonary bypass, cardiac surgery, coronary artery bypass, renal protection and renal preservation. Eligible articles consisted of all studies on patients who had undergone cardiac surgery via CPB with an outcome of AKI and/or RRT reported. All studies underwent a quality check via the risk of bias tool. The three most researched interventions (based on number of randomized controlled trials and total patients analysed) and their renal outcomes were then analysed with Review Manager Software. RESULTS: Eighty-eight articles were extracted. A total of 26 management strategies for renal protection following CPB were identified. N-acetylcysteine (NAC), remote ischaemic preconditioning (RIPC) and the use of volatile anaesthetic agents (VAAs) were further analysed. NAC, RIPC and VAA had no statistically significant benefit in reducing either AKI-CPB or the need for RRT following CPB. CONCLUSION: NAC, RIPC and VAA were found to have no statistical significant benefit in reducing either AKI-CPB or the need for RRT following CPB. There remains clinical uncertainty with all currently proposed pharmacological and non-surgical renal protective strategies for CPB. Future research in this area should analyse the effects of combined interventions or specifically focus on 'at-risk' patients.
