Critical care at the end of life: balancing technology with compassion and agreeing when to stop.
Modern intensive care saves lives. However, the substantial related financial costs are, for many, married to substantial costs in terms of suffering. In the most sick, the experience of intensive care is commonly associated with the development of profound physical debility, which may last years after discharge. ⋯ Efforts must be made to humanize intensive care as much as possible. Meanwhile, an open conversation must be held between those within the medical professions, and between such healthcare workers and the public in general, regarding the balancing of the positive and negative impacts of intensive care. Such conversations should extend to individual patients and their families when considering what care is genuinely in their best interests.

Observational Study
Is postspinal hypotension a sign of impaired cardiac performance in the elderly? An observational mechanistic study.
We have previously reported that stroke volume is reduced in a majority of elderly patients undergoing surgical repair of hip fracture before and after intrathecal injection of anaesthetic. We aimed to investigate these observations further in a prospective study of elderly patients undergoing elective hip or knee arthroplasty under spinal anaesthesia. ⋯ A decrease in cardiac output from baseline before spinal anaesthesia and an inability to increase it after induction may be important features of postspinal hypotension in elderly patients.

There is a consistent relationship between physical activity, physical fitness, and health across almost all clinical contexts, including the perioperative setting. Physiological measurements obtained during physical exercise may be used to infer the risk of adverse outcome after major surgery. In particular, data obtained from perioperative cardiopulmonary exercise testing have an expanding role in perioperative care. ⋯ Furthermore, studies evaluating exercise interventions aimed at increasing preoperative exercise capacity have established that training improves physical fitness. However, to date, this literature is largely composed of feasibility and pilot studies with small sample sizes, which are in general underpowered to assess clinical outcomes. Adequately powered prospective multicentre studies are needed to characterize the most effective means of improving patient fitness before surgery and to evaluate the impact of such improvements on surgical and disease-specific (e.g. cancer) outcomes.

The wars in Iraq and Afghanistan have helped to shape the modern Defence Medical Services. Many lessons were learnt including the need for rapid haemorrhage control, senior decision-making and the evolution of deployed transfusion support. These changes were implemented simultaneously with a coherent, end-to-end medical plan from point of wounding through to rehabilitation. ⋯ Military anaesthetists have a long pre-deployment training pathway starting with a Certificate of Completion of Training (CCT) in anaesthesia and/or critical care, and with an emphasis on military skills related to their specific role. Pre-deployment training includes additional skill training, team training and finally whole hospital collective training. This pathway ensures ongoing and continuing competence on an individual basis, and assurance that hospital management systems and clinical staff can function effectively as a deploying unit.
