Emergency department (ED) admissions have been rising over the last decades, especially in countries without any effective gate-keeping functions. Integration of walk-in clinics into the hospital might reduce ED-visits. Over a longer period, however, the additional service of a walk-in clinic might attract even more patients, nullifying an initial decrease in patients for the ED.This study aimed to determine short- and intermediate-term changes after the implementation of a hospital-integrated walk-in clinic. This is an observational study using routinely-collected health data. Study setting was the ED of a large tertiary care hospital in Austria, a country with universal health care and no regulations regarding level of care.ED-visits were compared between before (2015) and after (2017 and 2018) establishment of a hospital-integrated walk-in clinic.Total ED-visits decreased from 87,624 in 2015 to 67,479 in 2017, and 67,871 in 2018 (p 0.001), mainly due to a decrease in non-urgent (ESI 45) cases (45,715 (54.1%) in 2015; 33,142 (51.3%) in 2017; 30,846 (47.5%) in 2018; short term OR non-urgent vs. urgent: 0.89 (95% CI 0.88-0.91); intermediate term OR urgent vs. non-urgent: 0.76 (95% CI 0.78-0.75)). A total of 2611 (13%) (2017) and 1714 (8.5%) (2018) patients were referred back to the ED.After the introduction of the walk-in clinic, ED-visits declined significantly. This remained stable over a two-year period. Reduction in ED-visits was mainly due to low-acuity patients not requiring admission to the hospital.

Carbon monoxide (CO) is a leading cause of morbidity and mortality. Treatment focuses on the rapid elimination of CO and management of hypoxia. Oxygen is the cornerstone of therapy, and usually applied via a reservoir face mask. Hyperbaric oxygen therapy eliminates CO faster, but requires extensive equipment and expertise. Non-invasive continuous positive airway pressure (CPAP) ventilation using a tight mask provides a higher inspired fraction of oxygen (FiO2) compared to a reservoir face mask, and increases gas exchange. As this modality is widely available, it might represent a supplemental approach to current treatment of CO poisoning. We present two simultaneous cases of a married couple of 31- and 34-year-old patients, who concurrently suffered CO intoxication due to a faulty gas heater in their apartment. Both reported similar symptoms of headache and weakness, and carboxyhemoglobin (COHb)-levels at admission were 21% in both patients. One patient was treated by non-invasive CPAP-ventilation support with a FiO2 of 100%, whereas the other was treated by conventional oxygen inhalation. In the patient treated by CPAP, COHb-levels fell quickly to 6% within one hour, and reached 3% after 90 min, whereas it took six hours to reach the same levels in the patient with conventional treatment. This vividly illustrates the potential of CPAP therapy as an alternative to conventional oxygen inhalation in the treatment of CO poisoning.

Purpose To determine whether during the initial phase of head and neck cooling, jugular bulb temperature (Tjb; which may reflect brain temperature) is lower than esophageal temperature (Tes). Basic Procedures To compare Tes and Tjb, patients received head or head and neck cooling after cardiac arrest. Main Findings The first series with head cooling (n = 5; mean age 54 with a range of 41-62 years; 1 female and 4 males; mean body weight 80 kg with a range of 70-85 kg) showed a mean difference of 0.22°C (95% CI, −1.14 to 0.70; P = .55; limits of agreement, −3.17 to 2.73) between Tes and Tjb over 12 hours. For the second series, with head and neck cooling (n = 6, mean age 65 with a range of 56-76 years; 3 females and 3 males; mean body weight 75 kg with a range of 65-91 kg), Tjb was lower than Tes with a difference of 0.60°C (95% CI, 0.22 to 0.99; P = .01; limits of agreement, −3.10 to 4.30). During the first 3 hours, Tjb decreased faster than Tes (1.1°C/h [95% CI, 0.4 to 1.8; P Principal Conclusion During the initial phase of therapeutic hypothermia, Tjb seems to be lower than Tes.

To establish baseline data on prehospital emergencies caused by opiates during a 4-month period, a retrospective analysis of run records of the Emergency Medical System in Vienna, the capital of Austria, was conducted. During the study period, there were 308 opioid emergencies involving 240 persons, an average of 2.5 overdoses per day. Severely compromised patients were treated in 67.8% of the 308 emergencies, and 79.3% of emergencies were transported to hospital; 52.5% of the involved persons were younger than 22 years of age. Sex distribution and periodicity and frequency of emergencies differed among age groups. A subgroup of individuals involved repeatedly in emergencies was identified, partly showing temporal clustering of fatal and nonfatal overdoses. Persons involved in opiate emergencies belong to heterogenous subgroups. At a local level, research should be initiated to clarify the pattern and impact of these emergencies on overall drug abuse prevention.

Severe hypokalemia is a potentially life-threatening disorder and is associated with variable degrees of skeletal muscle weakness, even to the point of paralysis. On rare occasions, diaphragmatic paralysis from hypokalemia can lead to respiratory arrest. There may also be decreased motility of smooth muscle, manifesting with ileus or urinary retention. Rarely, severe hypokalemia may result in rhabdomyolysis. Other manifestations of severe hypokalemia include alteration of cardiac tissue excitability and conduction. Hypokalemia can produce electrocardiographic changes such as U waves, T-wave flattening, and arrhythmias, especially if the patient is taking digoxin. Common causes of hypokalemia include extrarenal potassium losses (vomiting and diarrhea) and renal potassium losses (eg, hyperaldosteronism, renal tubular acidosis, severe hyperglycemia, potassium-depleting diuretics) as well as hypokalemia due to potassium shifts (eg, insulin administration, catecholamine excess, familial periodic hypokalemic paralysis, thyrotoxic hypokalemic paralysis). Although the extent of diuretic misuse in professional bodybuilding is unknown, it may be regarded as substantial. Hence, diuretics must always be considered as a cause of hypokalemic paralysis in bodybuilders.

Epistaxis and hypertension are frequent in the general population, but an association is still controversial. Aim of this retrospective cohort study was to test if active epistaxis at emergency department (ED) presentation is associated with hypertension. Patients with active epistaxis at ED presentation (n = 271; 73%) were compared with controls without active bleeding (n = 101; 27%). By multivariate logistic regression modeling we found that active epistaxis was independently associated with history of hypertension (odds ratio 2.8 [95% CI 1.4 to 5.6; P =.004] adjusted for age, gender, rhinitis, diffuse bleeding, and malignant diseases). Patients with active epistaxis had higher blood pressure at presentation compared with controls (systolic blood pressure 165 v 153 mmHg, P

In a 6-month prospective study, the efficacy and safety of urapidil and nifedipine in an outpatient population with hypertensive urgencies (systolic blood pressure >200 mm Hg; diastolic blood pressure >110 mm Hg) was investigated. Response to treatment was defined as a stable reduction of systolic blood pressure below 180 mm Hg and diastolic blood pressure below 100 mm Hg 15 minutes after application of a single dose of either 25 mg urapidil intravenously (N = 26) or 10 mg nifedipine sublingually (N = 27). If the blood pressure was still elevated, a second dose of 10 mg nifedipine or 12.5 mg urapidil was given, and blood pressure response was evaluated 15 minutes after application of the second dose according to the aforementioned criterias. After the first application of nifedipine, 19 (70%) responders have been observed. Eight patients needed an additional 10 mg of nifedipine. In four of these patients, no reduction of blood pressure was observed after a second dose of nifedipine. In contrast, 24 (92%) patients responded well to the first application of 25 mg of urapidil. Two patients required a second dose of 12.5 mg of urapidil, but no nonresponder to urapidil was observed. No severe side-effects were noted in both groups. Intravenous urapidil is a highly effective drug in the treatment of hypertensive urgencies and is more effective than sublingual nifedipine, because the number of patients treated successfully was significantly higher.
