Ten-Year Review of Tracheostomy Techniques and Related Complications.

BACKGROUND: Tracheostomy is a frequently performed procedure that allows for definitive airway access in critically ill patients. Complications associated with tracheostomy have been well documented in the literature. This study aims to examine if different tracheostomy techniques were associated with specific complications. Secondary objectives were to determine the rate and commonality of post-tracheostomy complications. METHODS: This was a descriptive retrospective study of patients who underwent tracheostomy between June 2009 and June 2019. Patients included in the study were ≥18 years and were admitted to a rural tertiary care hospital system. RESULTS: Overall procedure complication rate was 34.3% with pneumonia (18.6%), obstruction (6.2%), bleeding (4.0%), and accidental tube decannulation (3.8%) being the most common. Rate of complications was not associated with the timing of the tracheostomy, the incision type, tube location, tracheostomy technique, and securing technique. However, tube size significantly differed between patients with or without complications (P = .016). Tube size 8 Shiley was most commonly used in both groups and was significantly associated with reduced complication rate (72.0% vs 78.8%, P = .002). CONCLUSION: Tracheostomy technique should be guided by proceduralist experience and patient clinical picture to determine the best approach. However, the association of post-tracheostomy complication with tube size perhaps will guide clinicians with tube size selection.

Prehospital Active and Passive Warming in Trauma Patients.

OBJECTIVE: Hypothermia is common among trauma patients and can lead to a serious rise in morbidity and mortality. This study was performed to investigate the effect of active and passive warming measures implemented in the prehospital phase on the body temperature of trauma patients. METHODS: In a multicenter, multinational prospective observational design, the effect of active and passive warming measures on the incidence of hypothermia was investigated. Adult trauma patients who were transported by helicopter emergency medical services (HEMS) or ground emergency medical services with an HEMS physician directly from the scene of injury were included. Four HEMS/ground emergency medical services programs from Canada, the United States, and the Netherlands participated. RESULTS: A total of 80 patients (n = 20 per site) were included. Eleven percent had hypothermia on presentation, and the initial evaluation occurred predominantly within 60 minutes after injury. In-line fluid warmers and blankets were the most frequently used active and passive warming measures, respectively. Independent risk factors for a negative change in body temperature were transportation by ground ambulance (odds ratio = 3.20; 95% confidence interval, 1.06-11.49; P = .03) and being wet on initial presentation (odds ratio = 3.64; 95% confidence interval, 0.99-13.36; P = .05). CONCLUSION: For adult patients transported from the scene of injury to a trauma center, active and passive warming measures, most notably the removal of wet clothing, were associated with a favorable outcome, whereas wet patients and ground ambulance transport were associated with an unfavorable outcome with respect to temperature.

A 10-Year Epidemiologic Overview of Firearm Injuries in Southern West Virginia.

The firearm mortality rate in West Virginia (WV) increased over the past four years and is currently 50% higher than the national rate. These alarming statistics, combined with the urban-to-rural shift in firearm injuries, prompted this 10-year epidemiologic overview. To the best of the authors' knowledge, the current study stands alone as the only report of its kind on firearm injuries in the rural setting of southern WV. Firearm injuries were common in White males within the age range of 20-49 years. Assault, which is typically identified as an urban problem, was found to be the most common injury in the study population. In our data series, injury severity score was the strongest predictor of mortality, followed by self-inflicted cause of injury and trauma to the neck/head region.

A pig model of tunneled dialysis catheter (TDC) infection and dysfunction: Opportunities for therapeutic innovation.

BACKGROUND: Although tunneled dialysis catheters (TDC) are far from ideal, they still represent the main form of vascular access for most patients beginning dialysis. Catheters are easy to place and allow patients instant access to dialysis, but regardless of these benefits, catheters are associated with a high incidence of significant complications like bloodstream infections, central venous stenosis, thrombosis, and dysfunction. In the present study, we aim to describe and characterize a swine model of catheter dysfunction and bloodstream infection, that recreates the clinical scenario, to help to serve as a platform to develop therapeutic innovations for this important clinical problem. METHODS: Six Yorkshire cross pigs were used in this study. Non-coated commercial catheters were implanted in the external jugular recreating the main features of common clinical practice. Catheters were aseptically accessed twice a week for a mock dialysis procedure (flushing in and out) to assess for and identify catheter dysfunction. Animals were monitored daily for infections; once detected, blood samples were collected for bacterial culture and antibiograms. Study animals were euthanized when nonresponsive to treatment. Tissue samples were collected in a standardized fashion for macroscopic inspection and histological analysis. RESULTS: The data analysis revealed an early onset of infection with a median time to infection of 9 days, 40% of the isolates were polymicrobial, and the average time to euthanasia was 20.16 ± 7.3 days. Median time to catheter dysfunction onset was 6 days post-implantation. Postmortem dissection revealed external fibrin sheath and internal thrombosis as the main causes of catheter dysfunction. There was also evidence of central venous stenosis with positive cells for αSMA, CD68, Ki67, Smoothelin, and Vimentin within the venous neointima. CONCLUSIONS: The described model represents a reliable and reproducible large animal model of catheter dysfunction and bloodstream infection, which recreates all the main complications of TDC's and so could be used as a validated large animal model to develop new therapies for TDC related infection, thrombosis/dysfunction and central venous stenosis.

Impact of the 24/7 nurse practitioner model on emergency department stay at a level 1 trauma center: A retrospective study.

AIMS: The aim of the study was to assess the impact of 24/7 trauma nurse practitioner service model on the emergency department patient flow. BACKGROUND: Seamless transition of trauma patients through the emergency department to inpatient hospital care is crucial for coordination of care, clinical safety and positive health outcomes. A level 1 trauma centre located in Southern West Virginia, USA expanded their trauma nurse practitioner service covering the emergency department 24/7. DESIGN: Retrospective cohort study conducted in accordance with the Strengthening the Reporting of Observational studies in Epidemiology guidelines. METHODS: Patients admitted to the trauma centre between March 2019 and February 2020 were divided into two groups: trauma patients managed by trauma nurse practitioners versus the hospitalist service. The hospital service group was chosen as the comparator group because any admission prior to night coverage by the trauma nurse practitioners were managed by the hospitalist service. RESULTS: The emergency department length of stay was significantly lower in trauma nurse practitioners' patients by an average of 300 min (772.25 ± 831.91 vs. 471.44 ± 336.65, p = <.001). Similarly, time to place emergency department discharge order was shorter by 49 min (277.76 ± 159.69 vs. 228.27 ± 116.04, p = .001) for this group. Moreover, trauma nurse practitioners on an average placed one less consultation (1.06 ± 0.23 vs. 1.46 ± 0.74, p < .001). CONCLUSION: The patient care provided by trauma nurse practitioners aided in the reduction of strain felt by their emergency department. They were able to help facilitate patient flow thus lessening the pressure of boarding in an overcrowded emergency department. The study institution hopes to sustain the current service model and continue to review outcomes and processes managed by trauma nurse practitioners to ensure consistency and quality. RELEVANCE TO CLINICAL PRACTICE: Similar trauma centres should evaluate the structure of their trauma service that includes the role of trauma nurse practitioner service and work towards allowing them to manage patient care from the emergency department 24/7.
