Anaesthesia
-
National reports recommended that peri-operative care should be improved for elderly patients undergoing emergency surgery. Postoperative mortality and morbidity rates remain high, and indicate that emergency ruptured aneurysm repair, laparotomy and hip fracture fixation are high-risk procedures undertaken on elderly patients with limited physiological reserve. National audits have reported variations in care quality, data that are increasingly being used to drive quality improvement through professional guidance. Given that the number of elderly patients presenting for emergency surgery is likely to rise as the population ages, this review summarises the evidence on which such guidance is based, and provides information about how anaesthetists might participate in audit and research aimed at improving local and national outcomes for these most vulnerable of patients.

Practice Guideline
Peri-operative care of the elderly 2014 : Association of Anaesthetists of Great Britain and Ireland.
Increasing numbers of elderly patients are undergoing an increasing variety of surgical procedures. There is an age-related decline in physiological reserve, which may be compounded by illness, cognitive decline, frailty and polypharmacy. Compared with younger surgical patients, the elderly are at relatively higher risk of mortality and morbidity after elective and (especially) emergency surgery. ⋯ Anaesthetists must not ration surgical or critical care on the basis of age, but must be involved in discussions about the utility of surgery and/or resuscitation. The evidence base informing peri-operative care for the elderly remains poor. Anaesthetists are strongly encouraged to become involved in national audit projects and outcomes research specifically involving elderly surgical patients.

The SonixGPS™ needle guidance positioning system provides navigation assistance to facilitate needle handling during ultrasound-guided procedures. Each of 20 inexperienced nurse anaesthetists performed 12 different ultrasound-guided tasks in a porcine phantom. Using both in-plane and out-of-plane approaches, they inserted a needle and made contact with metal rods at depths of 2, 4 and 6 cm. ⋯ Using the in-plane approach, the needle was more visible with navigation assistance: 24% vs 52% of execution time, respectively (95% CI: 44%-12%; p = 0.0025). Better needle visibility was associated with shorter execution times and fewer needle repositionings. Combining ultrasound-guided techniques with the needle guidance positioning system may reduce tissue manipulation, thus improving patient comfort and safety.
