The erector spinae plane block for acute pain management in emergency department patients with rib fractures.

OBJECTIVE: Rib fractures represent a significant cause of morbidity and mortality in trauma patients. The erector spinae plane block has come to the forefront as a potential safe and effective option for analgesia in painful conditions of the thorax over multiple dermatomal levels. Given the high morbidity associated with rib fractures, the inadequacy of opioid analgesia and the strong safety profile of the erector spinae plane block, this pilot study sought to address whether this block can be used to safely and effectively provide analgesia in emergency department (ED) patients with acute rib fractures. METHODS: A total of nine patients underwent the procedure successfully. Patients were found to have a significant reduction in their pain score pre- and post-block. The reduction in mean pre- and post-block pain scores was 9.89 vs 3.56 which was statistically significant (p < 0.0001). CONCLUSION: In a pilot sampling of emergency department patients with acute fractures who failed traditional analgesic therapy, the erector spinae plane block performed by emergency physicians provided safe and effective pain control. Further research is needed to fully establish the clinical benefit and safety of this procedure.

RéSUMé: OBJECTIFS: Les fractures des côtes représentent une cause importante de morbidité et de mortalité chez les patients traumatisés. Le bloc du plan des muscles érecteurs du rachis est apparu comme une option potentiellement sûre et efficace pour l'analgésie dans les états douloureux du thorax sur plusieurs niveaux dermatomiques. Compte tenu de la morbidité élevée associée aux fractures des côtes, de l'insuffisance de l'analgésie opiacée et du profil d'innocuité solide d'un bloc du plan des muscles érecteurs du rachis, cette étude pilote visait à déterminer si ce bloc peut être utilisé pour fournir une analgésie sûre et efficace aux patients des urgences présentant des fractures aiguës des côtes. MéTHODES: Au total, neuf patients ont subi l'intervention avec succès. On a constaté que les patients avaient une réduction significative de leur score de douleur avant et après le blocage. La réduction des scores moyens de la douleur avant et après le blocage était de 9.89 contre 3.56, ce qui était statistiquement significatif (p < 0.0001). CONCLUSION: Dans le cadre d'un projet pilote d'échantillonnage de patients des services d'urgence ayant subi des fractures aiguës et ayant échoué à la thérapie analgésique traditionnelle, le bloc du plan des muscles érecteurs du rachis effectué par les médecins urgentistes a permis de contrôler efficacement et en toute sécurité la douleur. Des recherches supplémentaires sont nécessaires pour établir pleinement les avantages cliniques et la sécurité de cette procédure.

Ultrasound-Guided Needle Aspiration of an Iliac Crest Abscess in a Pediatric Emergency Department.

Point-of-care ultrasound (POCUS) is an integral part of pediatric emergency medicine. One evolving use of POCUS is in the diagnosis and management of skin and soft tissue infections. Point-of-care ultrasound can be used to identify clinically occult infections and can be used to guide percutaneous drainage of both superficial and deep abscesses. Here, we present a case where POCUS- and US-guided needle aspiration had a significant impact on patient care by providing rapid diagnosis, as well as expediting microbiological speciation in a young male presenting with left-sided back and buttock pain.

Validity and utility of ICD-10 administrative health data for identifying ST- and non-ST-elevation myocardial infarction based on physician chart review.

BACKGROUND: Health care administrative databases are useful for assessing the population-level burden of disease and examining issues related to access, costs and quality of care. In these databases, the diagnoses and procedures are coded with the use of the World Health Organization International Classification of Diseases (ICD). We examined the validity of 2 ICD-10 coding definitions for categorizing patients with acute myocardial infarction (MI) as having ST-elevation MI (STEMI) or non-ST-elevation MI (non-STEMI). METHODS: Charts of patients with acute MI discharged between April and June 2007 from 3 hospitals in Edmonton, were reviewed to define the acute MI subtype (i.e., STEMI v. non-STEMI). The agreement between clinician chart review and STEMI/non-STEMI classification based on the standard (ICD-10 I21.x) and the supplementary electrocardiogram (ECG) codes (R94.3x) was determined. We assessed the effect of these alternative definitions on in-hospital mortality estimates by applying them to the data for all patients with acute MI admitted to hospital in the province from April 2007 to March 2010. RESULTS: Of the 297 patients, 49.2% were identified as having STEMI based on chart review, 44.4% using the standard definition, and 44.1% using the ECG definition. Both the standard and ECG definitions provided high agreement (92% for STEMI and 100% for non-STEMI) with the chart review classification. In the larger population-level cohort (n = 15 148), use of the standard definition or the ECG definition did not affect in-hospital mortality estimates for patients with STEMI and those with non-STEMI. INTERPRETATION: The standard definition appears equivalent to the definition using supplementary ECG codes to subcategorize patients with acute MI as having STEMI or non-STEMI. These findings may be relevant for the development of later versions of ICD codes.

Intact limbic-prefrontal connections and reduced amygdala volumes in Parkinson's disease with mild depressive symptoms.

BACKGROUND: Depression is very common in Parkinson's disease (PD). The neuropathological basis for this remains unclear; however, dysfunction in prefrontal and limbic regions may play a role. METHODS: We examined non-demented PD patients with and without depression and healthy controls (n = 6 per group) for differences in limbic structures and connections between these structures and the prefrontal cortex. Depressed individuals were selected from a representative sample of 33 PD patients using scores from the 15 question geriatric depression scale (GDS). Magnetic resonance diffusion tensor imaging (DTI) tractography was used to examine the structural integrity of the uncinate fasciculus (UF), a white matter tract that projects from the hippocampus, amygdala and temporal pole to the orbitofrontal cortex, and the corpus callosum. Integrity of the UF and corpus callosum was established through measures of mean diffusivity (MD), fractional anisotropy (FA) and tract length. A volumetric analysis of the hippocampal head, body and tail, as well as the amygdala was performed to determine whether volume differences in these structures in PD relate to depression. RESULTS: The depressed PD group showed smaller amygdala volumes compared to healthy controls, but the groups did not differ on any other measure. CONCLUSIONS: The present study found intact limbic connectivity but suggests that amygdala atrophy may be present in Parkinson's disease with depression. Further work is needed to replicate these findings.
