[Delirium: an interdisciplinary challenge]. / Delir : Eine interdisziplinäre Herausforderung.

Delirium, the acute deterioration of cognitive function and attention, is the most frequent mental disorder in elderly. Its correct diagnosis and adequate management are of crucial importance for the patient's health and functional outcome. First of all, one has to be aware of the possibilities of preventing this complex, potentially life-threatening problem, which means recognizing the patient at risk, avoiding environmental stress and causal factors (i.e., anticholinergic medication) in cognitively impaired patients, and timely reaction to prodromal symptoms. Causal therapy (i.e., treatment of the causal condition and/or eliminating the precipitating situation) is imperative. It must be accompanied by nursing and environmental measures and, if necessary, by antipsychotic and/or sedating symptomatic treatment.

Caring for people with dementia in general hospitals: an education curriculum from the Alzheimer's Society of Lower Saxony, Germany.

Since 2006, the Alzheimer's Society of Lower Saxony, Germany, has been working to improve care and medical treatment for people with cognitive impairment or dementia in general hospitals. An interdisciplinary team systematically worked on the topic for several years and presented results at various symposia. In 2011, a two-stage curriculum was completed and sent in combination with additional training documents to all hospitals and nursing training colleges in Lower Saxony, Germany. The manual comprised a two-step approach with a 14-h training for hospital staff and a 160-h training for qualification of trainers and dementia appointees/chaperones. In addition, the manual included a list of 13 essential points for "dealing with demented people in a general hospital," the information sheet of the German Alzheimer's Society on aspects requiring special attention when a demented person is admitted to a hospital, short descriptions of best practice models, a list of established speakers in the field, and a 30-min film. In 2012, the project won the "Preis für Engagement und Selbsthilfe" of the Hertie Foundation and the "Niedersächsischen Gesundheitspreis" awarded by the Lower Saxon Ministry for Social, Women, Family, and Health Affairs.

[Cessation of anesthesia after newly occurring anisocoria without light reflexes]. / Abbruch der Anästhesie bei neu aufgetretener Anisokorie mit fehlenden Lichtreflexen.

Anisocoria during general anaesthesia is rare. The combination of anisocoria and absence of any reaction to light is highly suspicious of an intracerebral lesion. This article reports the case of a patient with known Adie's syndrome where anisocoria led to an unnecessary immediate interruption of anesthesia. A preoperative examination, including inspection of the pupils, frequent perioperative check ups and documentation of diagnostic findings, even if negative, has to be standard for every anesthesia.

Continuous spinal analgesia or opioid-added continuous epidural analgesia for postoperative pain control after hip replacement.

BACKGROUND AND OBJECTIVE: Continuous spinal anaesthesia and continuous epidural anaesthesia are both able to provide adequate postoperative pain relief. Combining local anaesthetics and opioids results in synergistic effects. The purpose of this randomized, prospective study was to compare quality of analgesia, side-effects and patient's satisfaction between spinal bupivacaine alone and epidural bupivacaine with sufentanil postoperatively. METHODS: Fifty-nine patients scheduled for hip arthroplasty were randomly assigned either to Group 1 receiving continuous spinal anaesthesia or Group 2 receiving continuous epidural anaesthesia. Postoperatively, those in Group 1 received a 1 mL bolus followed by a continuous infusion of 10 mL/24 h of bupivacaine 0.25 %. Those in Group 2 received a 5 mL bolus of lidocaine 2%, followed by a continuous infusion of bupivacaine 0.25% with sufentanil 0.001 mg mL(-1) at 4 mL h(-1). Pain was measured using a verbal rating score and a visual analogue scale. RESULTS: Group 1 and Group 2 of 43.3% and 37.9% reported complete analgesia on the verbal rating score. No statistically significant difference was found in the visual analogue scale. Nausea and vomiting occurred significantly more often in Group 2. The patient satisfaction rates did not differ significantly. CONCLUSIONS: Continuous spinal analgesia with bupivacaine alone and continuous epidural analgesia with bupivacaine/sufentanil are both effective for postoperative pain relief after hip replacement. Those patients in the epidural group reported better analgesia but had a higher rate of postoperative nausea and vomiting. Efficacy of pain therapy did not correlate with patient satisfaction.
