An audit of perioperative blood transfusions in a regional hospital to rationalise a maximum surgical blood ordering schedule.
Appropriate preoperative blood typing and cross-matching is an important quality improvement target to minimise costs and rationalise the use of blood bank resources. This can be facilitated using a maximum surgical blood ordering schedule (MSBOS) for specific operations. It is recommended that individual hospitals develop a site-specific MSBOS based on institutional data, but this is challenging in non-tertiary centres without electronic databases. ⋯ The use of coding data represents an efficient method by which centres without electronic anaesthesia information management systems can conduct large-scale audits to develop a site-specific MSBOS. This would represent a significant improvement for hospitals that currently base preoperative testing recommendations on expert opinion alone. As many procedures in regional centres have very low transfusion rates, hospitals with a similar case mix to ours could consider selectively auditing higher-risk operations where local data is most likely to alter testing recommendations.

A survey of the impact of patient adverse events and near misses on anaesthetists in Australia and New Zealand.
We conducted a cross-sectional online survey of members of the Australian and New Zealand College of Anaesthetists to investigate their experiences of adverse patient safety events and near misses, including their use of incident reporting systems and the organisational support available. There were 247 respondents. Of the 243 anaesthetists whose patients had an adverse event or near miss, 199 reported this had affected them personally or professionally; 177 reported stress, 153 anxiety, 109 sleep disturbance, and 127 lower professional confidence. ⋯ Seventy-five anaesthetists admitted not reporting a safety incident that they knew they should have. Reasons for not reporting included an impression that nothing would improve from incident reporting, that reporting was onerous, or fears of punitive action. These findings should spur anaesthetists, anaesthetic departments and professional organisations across Australia and New Zealand to examine their support mechanisms in relation to adverse events and errors and their incident reporting mechanisms, and to attempt to improve these services where necessary.

Randomized Controlled TrialDoes a catheter over needle system reduce infusate leak in continuous peripheral nerve blockade: a randomised controlled trial.
Continuous peripheral nerve blockade is a common technique in the analgesic management for many procedures. Leakage of local anaesthetic from around the nerve catheter insertion site can increase the chance of catheter dislodgement, risks infective complications, and could divert anaesthetic away from the nerve causing the block to fail. We conducted a randomised controlled trial to assess whether the type of nerve catheter influenced local anaesthetic leak rate. ⋯ All seven instances of inadvertent catheter dislodgement occurred in the CTN group (P=0.006). There was no statistically significant difference between groups in the proportion of patients who had adequate analgesia on day one (CON 80% versus CTN 86.5%; P=0.294) and day two postoperatively (CON 85.5% versus CTN 91.8%; P=0.369). Our findings show the overall leak rate to be very low with both catheter systems; however, the CON system may have advantages in terms of speed of use and rate of inadvertent catheter dislodgement.

ReviewNutritional prehabilitation: physiological basis and clinical evidence.
In this narrative review, we describe the physiological basis for nutritional prehabilitation and evaluate the clinical evidence for its current roles in the perioperative period. Surgical stress and fasting induce insulin resistance as a result of altered mitochondrial function. Insulin resistance in the perioperative period leads to increased morbidity in a dose-dependent fashion, while preoperative carbohydrate loading attenuates insulin resistance, minimises protein loss and improves postoperative muscle function. ⋯ Clinical studies evaluating nutritional interventions have been marred by conflicting data, which may be due to small sample sizes, as well as heterogeneity of patients and surgical procedures. At present, it is known that carbohydrate loading is safe and improves patients' wellbeing, but does not appear to influence length of hospital stay or rate of postoperative complications. This should be appreciated before its routine inclusion in ERAS programs.
