Standardised peri-operative care pathways for patients undergoing emergency laparotomy or laparoscopy for non-traumatic pathologies have been shown to be inadequate and associated with high morbidity and mortality. Recent research has highlighted this problem and showed that simple pathways with 'rescue' interventions have been associated with reduced mortality when implemented successfully. These rescue pathways have focused on early diagnosis and surgery, specialist surgeon and anaesthetist involvement, goal-directed therapy and intensive or intermediary postoperative care for high-risk patients. ⋯ In order to move beyond rescue pathways and to establish enhanced recovery for emergency laparotomy, it is essential that research on both the peri-operative pathophysiology of the different main patient groups - intestinal obstruction and perforation - and the potentially differentiated impact of interventions is carried out. Procedure- and pathology-specific knowledge is lacking on key elements of peri-operative care, such as: multimodal analgesia; haemodynamic optimisation and fluid management; attenuation of surgical stress; nutritional optimisation; facilitation of mobilisation; and the optimal use and organisation of specialised wards and improved interdisciplinary collaboration. As such, the future challenges in improving peri-operative patient care in emergency laparotomy are moving from simple rescue pathways to establish research that can form a basis for morbidity- and procedure-specific enhanced recovery protocols as seen in elective surgery.

Anaesthetists are thought to be at increased risk of suicide amongst the medical profession. The aims of the following guidelines are: increase awareness of suicide and associated vulnerabilities, risk factors and precipitants; to emphasise safe ways to respond to individuals in distress, both for them and for colleagues working alongside them; and to support individuals, departments and organisations in coping with a suicide.

Regional anaesthesia has undergone several exciting advances in the past few decades. Ultrasound-guided techniques of peripheral nerve blockade have become the gold standard thanks to the associated improvements in efficacy, ease of performance and safety. This has increased the accessibility and utilisation of regional anaesthesia in the anaesthesia community at large and is timely given the mounting evidence for its potential benefits on various patient-centred outcomes, including major morbidity, cancer recurrence and persistent postoperative pain. ⋯ There is ongoing research into optimising continuous catheter techniques and their management, intravenous and perineural pharmacological adjuncts, and sustained-release local anaesthetic molecules. Finally, there is a growing appreciation for the critical role that regional anaesthesia can play in an overall multimodal anaesthetic strategy. This is especially pertinent given the current focus on eliminating unnecessary peri-operative opioid administration.

Randomized Controlled Trial
Efficacy of a new blood pressure monitor (inflationary non-invasive blood pressure, iNIBP™): a randomised controlled study.
The inflationary non-invasive blood pressure monitor (iNIBP™) uses a new measurement method, whereby the cuff is slowly inflated whilst simultaneously sensing oscillations, to determine the diastolic blood pressure first and then the systolic pressure. It may measure blood pressure more quickly than the conventional non-invasive blood pressure monitor. We studied 66 patients undergoing general anaesthesia, comparing the time taken to measure the blood pressure between the two monitors at times when there were marked changes (increases or decreases by 30 mmHg or greater) in the systolic blood pressure. ⋯ We also compared the degree of pain during cuff inflation between the automated non-invasive blood pressure and iNIBP monitors. Pain was significantly more for the non-invasive blood pressure monitor (22 of 30 volunteers had less pain with the iNIBP). We have shown that the iNIBP measured the blood pressure quicker than the conventional non-invasive blood pressure monitor and the speed of measurement was not significantly affected by marked changes in the blood pressure.
