Anaesthesia
-
These guidelines aim to ensure that patients with adrenal insufficiency are identified and adequately supplemented with glucocorticoids during the peri-operative period. There are two major categories of adrenal insufficiency. Primary adrenal insufficiency is due to diseases of the adrenal gland (failure of the hormone-producing gland), and secondary adrenal insufficiency is due to deficient adrenocorticotropin hormone secretion by the pituitary gland, or deficient corticotropin-releasing hormone secretion by the hypothalamus (failure of the regulatory centres). ⋯ Patients with previously undiagnosed adrenal insufficiency sometimes present for the first time following the stress of surgery. Anaesthetists must be familiar with the symptoms and signs of acute adrenal insufficiency so that inadequate supplementation or undiagnosed adrenal insufficiency can be detected and treated promptly. Delays may prove fatal.

Multicenter Study
Development and validation of a model to predict the need for emergency front-of-neck airway procedures in trauma patients.
The present study aimed to develop and validate a model for predicting the need for emergency front-of neck airway (eFONA) procedures among trauma patients. This was a multicentre retrospective cohort study using data from the Japan Trauma Data Bank between January 2004 and December 2017. Only adult trauma patients were included. ⋯ Setting the cut-off value at one for rule-out, the sensitivity and negative likelihood ratios were 0.86 and 0.22, respectively. Setting the cut-off value at two for rule-in, the specificity and positive likelihood ratios were 0.91 and 6.6, respectively. The present scoring system may assist in predicting the need for emergency front-of neck airway procedures among the general trauma population.

Review
Choice of local anaesthetic for epidural caesarean section: a Bayesian network meta-analysis.
Rapid-onset epidural local anaesthesia can avoid general anaesthesia for caesarean delivery. We performed a Bayesian network meta-analysis of direct and indirect comparisons to rank speed of onset of the six local anaesthetics most often used epidurally for surgical anaesthesia for caesarean delivery. We searched Google Scholar, PubMed, EMBASE, Ovid, CINAHL and CENTRAL to June 2019. ⋯ Speed of onset was similar to bupivacaine 0.5% after ropivacaine 0.75% and l-bupivacaine 0.5%: 1.6 (-1.4 to 4.8) min faster and 0.4 (-2.2 to 3.0) min faster, respectively. The rate (95%CrI) of intra-operative hypotension was least after l-bupivacaine 0.5%, 315 (236-407) per 1000, and highest after 2-chloroprocaine 3%, 516 (438-594) per 1000. The rate (CrI) of intra-operative supplementation of analgesia was least after ropivacaine 0.75% 48 (19-118) per 1000 and highest after 2-chloroprocaine 3%, 250 (112-569) per 1000.

Letter Guideline
PROSPECT guideline for oncological breast surgery: a systematic review and procedure-specific postoperative pain management recommendations.
Analgesic protocols used to treat pain after breast surgery vary significantly. The aim of this systematic review was to evaluate the available literature on this topic and develop recommendations for optimal pain management after oncological breast surgery. A systematic review using preferred reporting items for systematic reviews and meta-analysis guidance with procedure-specific postoperative pain management (PROSPECT) methodology was undertaken. ⋯ Paravertebral block may be continued postoperatively using catheter techniques. Opioids should be reserved as rescue analgesics in the postoperative period. Research is needed to evaluate the role of novel regional analgesic techniques such as erector spinae plane or retrolaminar plane blocks combined with basic analgesics in an enhanced recovery setting.

Randomized Controlled Trial
The effect of intrathecal bupivacaine/morphine on quality of recovery in robot-assisted radical prostatectomy: a randomised controlled trial.
Robot-assisted radical prostatectomy causes discomfort in the immediate postoperative period. This randomised controlled trial investigated if intrathecal bupivacaine/morphine, in addition to general anaesthesia, could be beneficial for the postoperative quality of recovery. One hundred and fifty-five patients were randomly allocated to an intervention group that received intrathecal 12.5 mg bupivacaine/300 μg morphine (20% dose reduction in patients > 75 years) or a control group receiving a subcutaneous sham injection and an intravenous loading dose of 0.1 mg.kg-1 morphine. ⋯ Moreover, the intervention group used less rescue medication. Pruritus was more severe in the intervention group; NRS 4 (1-7 [0-10]) vs. 0 (0-1 [0-10]), p = 0.000. We conclude that despite a modest increase in the incidence of pruritus, multimodal pain management with intrathecal bupivacaine/morphine remains a viable option for robot-assisted radical prostatectomy.
