[Pre-operative documentation of individual in-patient therapy goals : A medical staff questionnaire]. / Patientenorientierte Therapieziele im Krankenhaus : Eine Fragebogenerhebung an medizinischem Personal.

BACKGROUND: Perioperative care demands consideration of individual treatment goals. We evaluated the attitudes of medical staff towards a short standardized advance directive (SSAD) as a means of improving patient-orientated care at the transition from operating theater to general or intensive care wards. METHOD: Multicenter anonymized standardized multiple-choice questionnaire among physicians and nurses from various operative and anesthesiology departments. Questions addressing demographic parameters and attitudes towards advance directives in acute care settings (eleven 4­stepped Likert items). Univariate analysis of group comparisons using the chi-square and Kruskal-Wallis rank-sum test. Multivariable analysis of significant differences employing ordinal logistic regression. RESULTS: The overall return rate was 28.2 % (169 questionnaires). Of these, 19.5 % said that existing advance directives were regularly reassessed preoperatively. SSAD was expected to provide improved emergency care by 82.3 and 76.6 % thought that it would help to better focus intensive care resources according to patients' needs. DISCUSSION: Our study shows the dilemma of insufficiently structured directives for changing treatment goals as well as a high number of legal procedures to obtain proxy decisions due to missing out-patient advance health planning. From a medical staff perspective there is strong support for the concept of SSAD based on medical, ethical, economic and organizational reasons.

Cervical arthroplasty with ROTAIO® cervical disc prosthesis: first clinical and radiographic outcome analysis in a multicenter prospective trial.

BACKGROUND: Cervical Disc Arthroplasty (CDA) seems to be an alternative to Anterior Cervical Decompression and Fusion (ACDF) and was developed to minimize the risk of Adjacent Segment Disease (ASD). The ROTAIO Cervical Disc Prosthesis represents a new unconstrained implant with a variable centre of rotation which should enable physiological facet-guided movement. The aim of this current study was to evaluate the clinical outcomes after arthroplasty using ROTAIO Cervical Disc Prosthesis. METHOD: Twenty-seven female and 18 male patients (n = 45) with a mean age of 43.7 ± 7.8 years were prospectively followed up for a maximum of 24 month. Clinical outcomes were assessed by Neck Disability Index (NDI), visual analogue scale (VAS) scores for neck and arm pain, patients´ overall satisfaction and the usage of analgesics. Additionally, radiographic information including ROM of the functional spinal unit (FSU) and signs of adjacent segment disease were recorded. RESULTS: NDI and VAS scores showed significant improvement 6 months after surgery and at last follow-up (p < 0.001). Concerning overall satisfaction 95.7% of the patients showed good to excellent results at the last visit and a significant reduction of analgesic usage was observed (p < 0.001). Radiographic measurements showed a mean increase of ROM up to 8.40° in the treated FSU at last follow-up (p < 0.001). No signs of anterior migration or dislocation of the prosthesis and no subsidence was recorded radiographically. There were no major complications and a low rate of secondary procedures (2.2%). CONCLUSION: In the 24-months follow-up the ROTAIO Cervical Disc Prosthesis provided excellent clinical and radiographical results and seems to be safe and effective for the treatment of symptomatic single-level degenerative disc disease.

Continuous selective intraarterial infusion of nimodipine for therapy of refractory cerebral vasospasm.

BACKGROUND: For endovascular treatment of vasospasm after aneurysmal subarachnoid hemorrhage (aSAH), an intraarterial treatment course with the calcium channel antagonist nimodipine infused for 30 min is proposed. As some patients still show ongoing vasospasm thereafter, we report on our experience with an extended time period of selective intraarterial nimodipine administration. METHODS: In nine patients with aSAH and refractory cerebral vasospasm, we left the catheter in place within the internal carotid artery after angiography. On the neurosurgical ICU, a continuous infusion of intraarterial nimodipine was commenced, combined with intraarterial heparin anticoagulation. Therapy was controlled with extended neuromonitoring techniques. RESULTS: Three patients died from refractory vasospasm and a fourth suffered lethal sepsis. Three patients survived in a good clinical condition, two of them without apparent neurologic deficit. The efficacy of intraarterial nimodipine was best verified with regional CBF monitoring. TCD failed to detect vasospasm in two patients and missed improvement in four. Brain tissue oxygenation increased in all patients, but was not indicative of vasospasm in one. CT perfusion reflected the treatment course adequately in the qualitative scans. CONCLUSION: Selective continuous intraarterial nimodipine treatment for refractory cerebral vasospasm after aSAH seems feasible and may add to the endovascular therapeutic options. Appropriate monitoring technology is essential for further investigation of this novel technique.
