Anaesthesia

With increasing life expectancy and technological advancement, provision of anaesthesia for elderly patients has become a significant part of the overall case-load. These patients are unique, not only because they are older with more propensity for comorbidity but a decline in physiological reserve and cognitive function invariably accompanies ageing; this can substantially impact peri-operative outcome and quality of recovery. Furthermore, it is not only morbidity and mortality that matters; quality of life is also especially relevant in this vulnerable population. ⋯ The assessment of frailty has a central role in the pre-operative evaluation of the elderly. Other essential domains include optimisation of nutritional status, assessment of baseline cognitive function and proper approach to patient counselling and the decision-making process. Anaesthetists should be proactive in multidisciplinary care to achieve better outcomes; they are integral to the process.

Quality of life after critical illness is becoming increasingly important as survival improves. Various measures have been used to study the quality of life of patients discharged from intensive care. We systematically reviewed validated measures of quality of life and their results. ⋯ Quality of life improved for one year after hospital discharge. The aspects of life that improved most were physical function, physical role, vitality and social function. However, these domains were also the least likely to recover to population norms as they were more profoundly affected by critical illness.

Randomized Controlled Trial
The effect of force applied to the left paratracheal oesophagus on air entry into the gastric antrum during positive-pressure ventilation using a facemask.
Cricoid force is widely applied to decrease the risk of pulmonary aspiration and gastric antral insufflation of air during positive-pressure ventilation, yet its efficacy remains controversial. We compared manual oesophageal compression at the low left paratracheal and cricoid levels for the prevention of gastric antral air insufflation during positive-pressure ventilation by facemask in patients scheduled for elective surgery under general anaesthesia. After gaining written consent, participants were randomly allocated by sealed envelope to one of three groups: oesophageal compression by 30 N paratracheal force (paratracheal group); oesophageal compression by 30 N cricoid force (cricoid group); or no oesophageal compression (control group). ⋯ Before facemask ventilation, no air artefacts were visible in the antrum in any of the participants. After facemask ventilation of the participant's lungs, no air artefacts were seen in the paratracheal group, compared with six subjects in the cricoid group and eight subjects in the control group (p = 0.012). Our results suggest that oesophageal compression can be achieved by the application of manual force at the low left paratracheal level and that this is more effective than cricoid force in preventing air entry into the gastric antrum during positive-pressure ventilation by facemask.
