Health-related quality of life 90 days after stroke assessed by the International Consortium for Health Outcome Measurement standard set.

BACKGROUND AND PURPOSE: Stroke has detrimental effects in multiple health domains not captured by routine scales. The International Consortium for Health Outcome Measurement has developed a standardized set for self-reported assessment to overcome this limitation. The aim was to assess this set in acute stroke care. METHODS: Consecutive patients with acute ischaemic stroke, transient ischaemic attack or intracerebral hemorrhage were enrolled. Demographics, living situation and cardiovascular risk factors were collected from medical records and interviews. The Patient-reported Outcomes Measurement Information System 10-Question Short Form (PROMIS-10) and the Patient Health Questionnaire-4 (PHQ-4) were conducted 90 days after admission. Linear and logistic regression analyses were used to identify predictors of outcome. The study is registered at ClinicalTrials.gov, NCT03795948. RESULTS: In all, 1064 patients were enrolled; mean age was 71.6 years, 51% were female, and median National Institutes of Health Stroke Scale (NIHSS) on admission was 3. Diagnosis was acute ischaemic stroke in 74%, transient ischaemic attack in 20% and intracerebral hemorrhage in 6%. 673 patients were available for outcome evaluation at 90 days; of these 90 (13%) had died. In survivors, t scores of PROMIS-10 physical and mental health were 40.3 ± 6.17 and 44.3 ± 8.63, compared to 50 ± 10 in healthy populations. 16% reported symptoms indicating depression or anxiety on the PHQ-4. Higher NIHSS, prior stroke and requiring help pre-stroke predicted lower values in physical and mental health scores. Higher NIHSS and diabetes were associated with anxiety or depression. CONCLUSIONS: Integrated in the routine of acute stroke care, systematic assessment of patient-reported outcomes reveals impairments in physical and mental health. Main predictors are severity of stroke symptoms and comorbidities such as hypertension and diabetes.

[Business organization theory: its potential use in the organization of the operating room]. / Grundlagen der betriebswirtschaftlichen Organisationstheorie und ihre Bedeutung für den täglichen Operationsbetrieb.

The paradigm of patient care in the German health system is changing. The introduction of German Diagnosis Related Groups (G-DRGs), a diagnosis-related coding system, has made process-oriented thinking increasingly important. The treatment process is viewed and managed as a whole from the admission to the discharge of the patient. The interfaces of departments and sectors are diminished. A main objective of these measures is to render patient care more cost efficient. Within the hospital, the operating room (OR) is the most expensive factor accounting for 25 - 50 % of the costs of a surgical patient and is also a bottleneck in the surgical patient care. Therefore, controlling of the perioperative treatment process is getting more and more important. Here, the business organisation theory can be a very useful tool. Especially the concepts of process organisation and process management can be applied to hospitals. Process-oriented thinking uncovers and solves typical organisational problems. Competences, responsibilities and tasks are reorganised by process orientation and the enterprise is gradually transformed to a process-oriented system. Process management includes objective-oriented controlling of the value chain of an enterprise with regard to quality, time, costs and customer satisfaction. The quality of the process is continuously improved using process-management techniques. The main advantage of process management is consistent customer orientation. Customer orientation means to be aware of the customer's needs at any time during the daily routine. The performance is therefore always directed towards current market requirements. This paper presents the basics of business organisation theory and to point out its potential use in the organisation of the OR.

[Tube obstruction in operation of esophageal atresia. Brief review of intraoperative complications based on a case report]. / Tubusobstruktion bei der Operation einer Osophagusatresie. Kurzübersicht intraoperativer Komplikationen anhand einer Kasuistik.

In this case report we discuss the anaesthetic management of newborns with esophageal atresia classified as Vogt III b. This type is characterised by an upper esophageal pouch which ends blindly and a distal tracheoesophageal fistula. Commonly associated diseases are cardiac, renal, vertebral and anal anomalies. The most important intraoperative anaesthesiological complications are acidosis, hypoxaemia, gastric distension, endotracheal tube obstruction, tracheal compression, cardiac arrhythmias and atelectasis. In the presented case an endotracheal tube obstruction with hypercapnia occurred which required a change of the airway. After changing the endotracheal tube the newborn could be ventilated sufficiently. Further postoperative course was uneventful.

Anaesthetic management of patients with mucopolysaccharidosis IV presenting for major orthopaedic surgery.

Mucopolysaccharidosis IV, also known as Morquio-Brailsford syndrome, is an inherited autosomal recessive disorder of mucopolysaccharide metabolism leading to accumulation of keratan sulphate in the connective tissue of multiple organ systems. Based on a case report, the anaesthetic implications for the treatment of patients with MPS IV presenting for major orthopaedic surgery are discussed.

Non-thermoregulatory shivering in patients recovering from isoflurane or desflurane anesthesia.

BACKGROUND: Although cold-induced shivering is an obvious source of postanesthetic tremor, other causes may contribute. Consistent with this theory, the authors had previously identified an abnormal clonic component of postoperative shivering and proposed that it might be nonthermoregulatory. A subsequent study, however, failed to identify spontaneous muscular activity in normothermic volunteers. These data suggested that the initial theory was erroneous or that a yet-to-be identified factor associated with surgery might facilitate shivering in patients after operation. Therefore, the authors tested the hypothesis that some postoperative tremor is nonthermoregulatory. METHODS: One hundred twenty patients undergoing major orthopedic operation were observed. They were grouped randomly to receive maintenance anesthesia with nitrous oxide and isoflurane (0.8 +/- 0.4%) or desflurane (3.4 +/- 1.1%). Twenty patients in each group were allowed to become hypothermic, whereas normal body temperatures were maintained in the others (tympanic membrane temperature exceeding preinduction values). Arteriovenous shunt vasoconstriction was evaluated using forearm-minus-fingertip skin-temperature gradients; gradients less than 0 degrees C identified vasodilation. Postanesthetic shivering was graded by a blinded investigator. Tremor in patients who were normothermic and vasodilated was considered nonthermoregulatory. RESULTS: Thermoregulatory responses were similar after isoflurane or desflurane anesthesia. Approximately 50% of the unwarmed patients shivered. Shivering was observed in 27% of the patients who were normothermic; 55% of this spontaneous muscular activity occurred in vasodilated patients. Among the normothermic patients, 15% fulfilled the authors' criteria for nonthermoregulatory tremor. CONCLUSIONS: The incidence of postoperative shivering is inversely related to core temperature. Therefore, it was not surprising that shivering was most common among the hypothermic patients. The major findings, however, were that shivering remained common even among patients who were kept scrupulously normothermic and that many shivered while they were vasodilated. Thus, postoperative patients differ from nonsurgical volunteers in demonstrating a substantial incidence of nonthermoregulatory tremor.
