Malignant hyperthermia (MH), a metabolic myopathy triggered by volatile anesthetics and depolarizing muscle relaxants, is a potentially lethal complication of general anesthesia in susceptible patients. The implementation of modern inhalation anesthetics that research indicates as less potent trigger substances and the recommended limitations of succinylcholine use, suggests there may be considerable decline of fulminant MH cases. In the presented study, the authors analyzed suspected MH episodes during general anesthesia of patients that were referred to the Wuerzburg MH unit between 2007 and 2011, assuming that MH is still a relevant anesthetic problem in our days. ⋯ MH is still an important anesthetic complication. Every anesthetist must be aware of this life-threatening syndrome at any time. The rapid onset of adequate therapy is crucial to avoid major harm and possibly lethal outcome. Dantrolene must be readily available wherever MH triggering agents are used for anesthesia.

In trauma patients intubated in a physician-led pre-hospital trauma service we prospectively examined the rate of misplaced tracheal tubes, the presence and nature of gross airway contamination, and the value of 'quick look' airway assessment to identify patients with subsequent difficult laryngoscopy. ⋯ This study suggests that when physicians perform pre-hospital anaesthesia they have high intubation success rates and the use of ETCO2 monitoring reduces or eliminates undetected misplaced tracheal tubes. We found high rates of airway contamination; mostly blood from the upper airway. The 'quick look' airway assessment had some utility but is unreliable in isolation.

Goal-directed fluid therapy (GDFT) has been shown to reduce complications and hospital length of stay following major surgery. However, there has been no assessment regarding its use in clinical practice. ⋯ Several hypotheses were generated regarding important differences in the use of GDFT between anaesthetists from the UK and AUS/NZ. There is significant interest in utilising GDFT in clinical practice and existing barriers should be addressed.

⋯ This study identified postoperative delirium as an independent risk factor for mortality 6 months after hepatectomy. After 6 months, survivors were more dependent in instrumental ADL tasks and had worse scores in the physical function domain of SF-36.

A study by Burkle et al. in BMC Anesthesiology examined attitudes around perioperative do-not-resuscitate orders. Questionnaires were given to patients, as well as to anesthesiologists, internists and surgeons. The study has limitations and is open to interpretation. ⋯ However, this article could also encourage a broader debate. This is about how to respect patient autonomy, while ensuring that resuscitation truly serves the patient's best interests. This commentary outlines how more communication is needed at the bedside and in wider society.
