Sugammadex belongs to a new class of drugs termed selective relaxant binding agents and is now available for clinical use in over 50 countries. Because of its innovative mechanism of action, reversal of rocuronium or vecuronium becomes independent of the degree of residual neuromuscular blockade. Deep or intense neuromuscular blockade now can rapidly and predictably be reversed. However, compared with the classical acetylcholine esterase inhibitor-based reversal treatment costs are significantly higher. On the basis of the current literature, the cost-effectiveness of sugammadex will be evaluated. ⋯ The reduction of recovery times with sugammadex will reduce the incidence of prolonged extubation and may increase patients' throughput. However, the achievable reduction of costs depends on the individual organizational factors, also.

ReviewCardiopulmonary exercise testing: does it improve perioperative care and outcome?
We reviewed recent articles, guidelines, and meta-analyses concerning the use of cardiopulmonary exercise testing (CPET) in preoperative risk evaluation and fitness for surgery. When the risk of surgery mortality is high (e.g. >5%), and/or the preoperative state of the patient indicates increased propensity toward morbidity and mortality (advanced age, presence of cardiovascular risk factors, multisystem disease, poor functional status, and so on), the thoroughness of the perioperative assessment should be intensified beyond the standard history and physical, basic laboratories, and electrocardiogram stress testing to include CPET. ⋯ Using a small number of important variables obtained from CPET an accurate picture of the patient's future response to perioperative stress can be obtained. Consideration should be given to performing a CPET in any preoperative patient who has increased risk or is scheduled to undergo a high risk surgical intervention. This strategy assists the anesthetist, surgeon, patients, and their families in appropriate perioperative planning.

Conventional wisdom maintains that multiple aspects of surgical technique and management may affect postoperative outcome, while anaesthetic technique has little long-term effect on patient outcomes. There is accumulating evidence that, on the contrary, anaesthetic management may in fact exert a number of longer-term effects in postoperative outcome. Here, we review the most topical aspects of anaesthetic management which may potentially influence later postoperative outcomes. ⋯ Further prospective, large-scale human trials with long-term follow-up are required to clarify the association between anaesthesia and cancer recurrence, neurotoxicity and the developing brain and long-term postoperative cognitive dysfunction in the elderly.

To describe the most recent advances and clinical applications of adjunctive techniques in mechanical ventilation, focusing on their overall impact on mortality and their potential indications in critically ill patients. ⋯ Giving the complexity and dynamism of acute lung injury, timing, severity, and pathophysiologic pertinence are mandatory components of decision-making when considering the application of adjunctive measures to support mechanical ventilation.

Recent therapeutic and observational studies have demonstrated improved survival with better management of haemostasis early after injury. This review delineates our current understanding of the clinical importance, aetiology and pathophysiology of acute traumatic coagulopathy (ATC). ⋯ Conventional concepts of traumatic coagulopathy as a late occurring condition in response to iatrogenic haemodilution are redundant. ATC is an endogenous impairment of haemostasis that begins at the moment of injury. Further outcome improvements are possible with better understanding of the process by which this coagulopathy develops and how it may be inhibited.
