[Patient safety in differentiated (in-hospital) activation of the resuscitation room for severely injured patients]

BACKGROUND AND OBJECTIVE

Providing trauma services demands high personnel resources and structural costs. The goal of this study was to show if the assignment of trauma patients to a defined A or B resuscitation room treatment as a modified management concept is safe and feasible.

MATERIAL AND METHODS

Between May 2020 and January 2021, all resuscitation room trauma patients were included in this single center prospective observational study. All patients admitted to the resuscitation room underwent a classification according to the German S3 guidelines grade of recommendation GoR A and GoR B in polytrauma and the status of the ABCDE sequence to an A and B resuscitation room. The classification was performed by the senior consultant on call via telephone after consultation and discussion of clinical findings.

RESULTS

All 135 resuscitation room patients were included in the study of whom 42 trauma patients were assigned to the A resuscitation room (A-SR) and 93 were assigned to the B resuscitation room (B-SR). The comparison of the two groups showed that patients in the A‑SR group are more likely to be accompanied by a prehospital emergency physician (80.5%) than patients in the B‑SR group (55.5%). Patients in the B‑SR group showed a significantly higher Glasgow coma scale (GCS). Using the eFAST emergency ultrasound protocol, 2.4% of the A‑SR and 4.3% of the B‑SR patients had trauma-associated pathologies, 26% of the A‑SR and only 3.2% of the B‑SR patients had to be admitted to the ICU, 21.4% of the A‑SR and 1% of the B‑SR patients died within 30 days after trauma. The injury severity scores (ISS) of the A‑SR patients were significantly higher than in the B‑SR group (ISS 28.3 vs. 6.8).

CONCLUSION

The study confirmed that the assignment by the emergency department consultant according to the German S3 guideline in combination with the ABCDE sequence into resuscitation room A or B treatment is feasible, does not compromise the quality of care and is efficient in the use of the personnel resources.

Effect of controlled-release levodopa on the microstructure of sleep in Parkinson's disease

BACKGROUND

Dopamine is an important neurotransmitter in the regulation of the sleep-wake cycle, and parkinsonian patients suffer from prominent sleep abnormalities. Hence, the question arises whether the disrupted sleep pattern in Parkinson's disease (PD) is responsive to dopaminergic treatment.

METHODS

Thirty-two patients (18 women, 45-82 years old; mean 61 ± 8 years) with dopamine-responsive, akinetic-rigid PD, not taking neuroleptic medication or suffering from dementia were randomized into two groups. Both groups had to withhold their usual dopaminergic medication after noon. At bedtime, one group received 200 mg controlled-release (CR) levodopa/carbidopa, whilst the other group spent the night in the 'off'-state. Polysomnographic recordings were obtained in all patients and 16 age-matched, healthy controls.

RESULTS

Compared to healthy controls, patients with PD suffered from significantly decreased total sleep time, REM sleep and slow wave sleep (SWS), whilst the time spent awake was increased. The administration of levodopa/carbidopa CR had no impact on any of these variables.

CONCLUSION

Levodopa/carbidopa CR has previously been found effective for treating night-time akinesia, but according to this study, it has no impact on the altered sleep structure in PD.

Stimulation of subthalamic fibre tracts reduces dyskinesias in STN-DBS

Rarely, the postoperative management of patients with subthalamic deep brain stimulation (STN-DBS) is complicated by pharmacologically intractable dyskinesias. Here we report that in three of these patients additional stimulation of a proximal contact located within the subthalamic white matter may lead to a significant reduction of dyskinesias associated with STN-DBS. We propose that pallidofugal fiber tracts play a major role in the etiopathology of dyskinesias and their blockade through DBS may explain our observations.
