Emergencies on or in water are relatively rare in the rescue service. For this reason, water accident treatment and management does not receive much attention in the training of emergency medicine physicians. ⋯ In Germany the number of non-swimmers is also increasing, so it can be assumed that the number of water-related accidents will continue to rise. Drowning accidents and near drowning are important in this context and will be discussed in detail in this review as well as hypothermia (a frequent problem), accompanying injuries and diving accidents.

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.

The number of diagnostic and surgical procedures being performed outside the core operating area is growing disproportionately. Due to the higher perioperative risk for such patients, anesthesia should only be provided by a very experienced anesthesiologist, even for supposedly small interventions. At these locations, timely and direct access to the anesthesia machine and/or the patient is often limited and if additional personnel or supplies are required, substantial time delays usually occur and should be allowed for. ⋯ For angiography, maximum monitoring needs to be available to provide hemodynamically unstable patients with adequate anesthesia care; comprehensive radiation protection for patients and staff as well as temperature monitoring for prolonged diagnostic procedures is also necessary. Monitoring oxygen saturation and end-tidal carbon dioxide as well as employing visual and audible alarms is an essential requirement even during conscious sedation. In summary, the number of diagnostic and surgical procedures performed outside the core operating area should be reduced to a minimum and, whenever possible, diagnostic or surgical procedures should be performed within the core operating area.

Priming can significantly shorten the onset of nondepolarizing neuromuscular blocking agents (NNBA) measured at the adductor pollicis muscle (APM). In spite of the known risks, priming is very popular especially in cases where NNBAs with a long onset time are used. However, there are no data regarding the onset of action for a priming technique measured at the laryngeal muscles although these muscles are of great importance for conditions of intubation and patient safety. The aim of this study was to compare a bolus application and a priming technique with respect to the laryngeal onset time and peak effect. ⋯ Our results show that only high dose priming of cisatracurium can significantly shorten the laryngeal onset time. However, clinical routine use is not recommended due to possible side-effects.

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.
