The DIFFMASK score for predicting difficult facemask ventilation: a cohort study of 46,804 patients.
Facemask ventilation is an essential part of airway management. Correctly predicting difficulties in facemask ventilation may reduce the risk of morbidity and mortality among patients at risk. We aimed to develop and evaluate a weighted risk score for predicting difficult facemask ventilation during anaesthesia. ⋯ The Youden index indicated a sum score ≥ 5 as an optimal cut-off value for prediction of difficult facemask ventilation giving a sensitivity of 85% and specificity of 59%. The DIFFMASK score indicated that a score of 6-10 points represents a population of patients who may require heightened attention when facemask ventilation is planned, compared with those patients who are obviously at a high- or low risk of difficulties. The DIFFMASK score may be useful in a clinical context but external, prospective validation is needed.

Observational Study
Measurement of extravascular lung water to diagnose severe reperfusion lung injury following pulmonary endarterectomy: a prospective cohort clinical validation study.
The measurement of extravascular lung water is a relatively new technology which has not yet been well validated as a clinically useful tool. We studied its utility in patients undergoing pulmonary endarterectomy as they frequently suffer reperfusion lung injury and associated oedematous lungs. Such patients are therefore ideal for evaluating this new monitor. ⋯ Peri-operative extravascular lung water index is not a useful measure to predict severe reperfusion lung injury after pulmonary endarterectomy, however, it does allow monitoring and measurement during the postoperative period. This study implies that extravascular lung water index can be used to directly assess pulmonary fluid overload and that monitoring patients by measuring extravascular lung water index during their intensive care stay is useful and correlates with their clinical course. This may allow directed, pre-empted therapy to attenuate the effects and improve patient outcomes and should prompt further studies.

Rotator cuff repair can be associated with significant and difficult to treat postoperative pain. We aimed to evaluate the available literature and develop recommendations for optimal pain management after rotator cuff repair. A systematic review using procedure-specific postoperative pain management (PROSPECT) methodology was undertaken. ⋯ No evidence was found for stellate ganglion block, cervical epidural block, specific postoperative rehabilitation protocols or postoperative compressive cryotherapy. The analgesic regimen for rotator cuff repair should include an arthroscopic approach, paracetamol, non-steroidal anti-inflammatory drugs, dexamethasone and a regional analgesic technique (either interscalene block or suprascapular nerve block with or without axillary nerve block), with opioids as rescue analgesics. Further randomised controlled trials are required to confirm the influence of the recommended analgesic regimen on postoperative pain relief.

There is growing evidence that anaesthetic trainees experience, and may be particularly susceptible to, high levels of work stress, burnout and depression. This is concern for the safety and wellbeing of these doctors and for the patients they treat. To date, there has been no in-depth evaluation of these issues among UK anaesthetic trainees to examine which groups may be most affected, and to identify the professional and personal factors with which they are associated. ⋯ Although female respondents reported higher stress, burnout risk was more likely in male respondents. This information could help in the identification of at-risk groups as well as informing ways to support these groups and to influence resource and intervention design. Targeted interventions, such as modification of exercise behaviour and methods of reducing stressors relating to non-clinical workloads, warrant further research.
