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.

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.

Randomized Controlled Trial Comparative Study
An experimental study comparing the respiratory effects of tapentadol and oxycodone in healthy volunteers.
There is a clinical need for potent opioids that produce little or no respiratory depression. In the current study we compared the respiratory effects of tapentadol, a mu-opioid receptor agonist and noradrenaline reuptake inhibitor, and oxycodone, a selective mu-opioid receptor agonist. We hypothesize that tapentadol 100 mg has a lesser effect on the control of breathing than oxycodone 20 mg. ⋯ In this exploratory study we observed that both tapentadol and oxycodone produce respiratory depression. Tapentadol 100 mg but not 150 mg had a modest respiratory advantage over oxycodone 20 mg. Further studies are needed to explore how these results translate to the clinical setting.
