In many hospitals operating room (OR) utilization rates and turnover times (the time from the end of the previous surgical procedure to the beginning of the next) are used as indicators of OR workflow inefficiency. However, there have been no detailed studies to determine whether these indicators really provide an adequate picture of avoidable wasting of time in the OR. ⋯ Utilization rate and perioperative turnover time cannot be used as indicators of OR workflow efficiency, since they cannot identify the days during which avoidable waiting times occur. If the aim is to identify underused OR time and factors that hamper workflow efficiency, waiting times and times without scheduled cases need to be recorded directly and separately.

In only a few contexts is the need for substantial learning more pronounced than in health care. For a health care provider, the ability to learn is essential in a changing environment. Although individual humans are programmed to learn naturally, organisations are not. ⋯ Learning organisations move beyond simple employee training into organisational problem solving, innovation and learning. Therefore, teamwork and leadership are necessary. Successful organisations change the competencies of individuals, the systems, the organisation, the strategy and the culture.

Case Reports
[Vasopressin as a rescue vasopressor agent. Treatment of selected cardiogenic shock states].
Vasodilatory shock is the most common form of shock in the critically ill patient. As a consequence of overwhelming and prolonged mediator production, vasodilatory shock can be the common final pathway of primary non-vasodilatory shock (e.g. cardiogenic or hypovolemic shock). ⋯ The hemodynamic effects of AVP were comparable to those AVP-induced alterations described in septic shock and seem to be predominantly mediated by potent vasoconstriction and the facilitated reduction of higher, potentially toxic catecholamine doses. Thus, an AVP-induced decrease in heart rate and pulmonary arterial pressures may be particularly beneficial in patients with impaired cardiac function.

Angioneurotic orolingual edema associated with the use of rt-PA (recombinant tissue plasminogen activator) for systemic thrombolysis are described in the literature, but only as isolated case reports. Strangely, the rate of anaphylactic reactions to rt-PA is higher (1.9%) when they are used in the treatment of acute stroke than when they are given to treat acute myocardial infarction (0.02%). Patients who are taking ACE inhibitors seem to be at increased risk of such a potentially life-threatening event. ⋯ Both these patients were taking ACE inhibitors. It was possible to avoid intubation and ventilation in both cases. Therapy with ranitidine, clemastine, and a C1 esterase inhibitor resulted in the resolution of symptomatic angioneurotic edema within hours.

Knowledge about the incidence of errors in anaesthesia and intensive care is only rudimentary but it appears justified to assume that errors occur much more often than we all expect. One reason is most likely the complexity of our work. ⋯ The article summarizes several methods to identify errors within a health care system and strengthens the importance of error analysis to reduce its incidence. Results of an analysis should be published if they are of general interest.
