ABSTRACT

OBJECTIVES: Pneumomediastinum (PNM) is a rare complication of mechanical ventilation, but its reported occurrence in patients with acute respiratory distress syndrome secondary to COVID-19 is significant. The objective is to determine the incidence, risk factors, and outcome of PNM in non-ICU hospitalized patients with severe-to-critical COVID-19 pneumonia. DESIGN: Retrospective observational study. SETTING: Population-based, single-setting, tertiary-care level COVID treatment center. PATIENTS: Individuals hospitalized with a diagnosis of COVID-19 pneumonia and severe to critical illness were included. Those hospitalized without respiratory failure, observed for less than 24 hours, or admitted from an ICU were excluded. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: All patients underwent a complete clinical assessment and chest CT scan, and were followed up from hospitalization to discharge or death. The outcome was the number of cases of PNM, defined as the presence of free air in the mediastinal tissues diagnosed by chest CT scan, in non-ICU hospitalized patients and the subsequent risk of intubation and mortality. PNM occurred in 48 out of 331 participants. The incidence was 14.5% (95% CI, 10.9-18.8%). A CT-Scan Severity score greater than 15 was positively associated with PNM (odds ratio [OR], 4.09; p = 0.002) and was observed in 35.2% of the participants (95% CI, 26.2-44.9%). Noninvasive ventilation was also positively associated with PNM (OR, 4.46; p = 0.005), but there was no positive association with airway pressures. Fifty patients (15%) were intubated, and 88 (27%) died. Both the risk for intubation and mortality were higher in patients with PNM, with a hazard ratio of 3.72 ( p < 0.001) and 3.27 ( p < 0.001), respectively. CONCLUSIONS: Non-ICU hospitalized patients with COVID-19 have a high incidence of PNM, increasing the risk for intubation and mortality three- to four-fold, particularly in those with extensive lung damage. These findings help define the risk and outcome of PNM in severe-to-critical COVID-19 pneumonia in a non-ICU setting.

ABSTRACT

Several studies have suggested the potential role of Magnesium Sulfate (MgSO4) for the treatment of Atrial Fibrillation (AF) but, in clinical practice, the use of magnesium is not standardized although it is largely used for the treatment of supraventricular arrhythmias. Objectives. We evaluated the role of MgSO4 infusion in association with flecainide in cardioversion of patients presenting in ED with symptomatic AF started less than 48 h before. We retrospectively searched for all patients presented in ED from 1 January 2019 to 31 December 2019 requiring pharmacological cardioversion with flecainide 2 mg/kg. Ninety-seven patients met these criteria, 46 received the administration of intravenous MgSO4 2 gr (Group A), and 51 did not (Group B). Among the 97 patients, the overall cardioversion rate was 85.6%, 91.3% in Group A and 80.4% in Group B. In 27 patients out of 97, the Flecainide was not administered because of spontaneous restoration of sinus rhythm of 9 pts (Group B) and 18 pts (Group A). We also found a statistical significance in the HR at the time of cardioversion between Group A (77.8 ± 19.1 bpm) and Group B (87 ± 21.7 bpm). No complications emerged. The association between MgSO4 and Flecainide has not yielded statistically significant results. However, in consideration of its high safety profile, MgSO4 administration may play a role in ED cardioversion of acute onset AF, reducing the need for antiarrhythmic medications and electrical cardioversion procedures, relieving symptoms reducing heart rate, and reducing the length of stay in the ED.

ABSTRACT

BACKGROUND: In the daily management of peripheral venous access, the health emergency linked to the COVID-19 pandemic led to re-examining the criteria for choosing, positioning and maintaining the different types of peripheral venous access. OBJECTIVES: This study aimed to observe the dwell time of long peripheral cannula (LPC, also known as mini-midline) in patients affected by COVID 19 related pneumonia. The secondary objective is to study any complications due to mini-midline insertion. MATERIALS AND METHODS: We conducted a prospective observational study on COVID19 patients who arrived at our Semi-Intensive Respiratory Unit from territorial ED between January and April 2021, to whom were positioned an LPC at the time of admission following the SIPUA protocol (Safe Insertion of Peripheral Ultrasound-guided Access). We used Vygon™ Leader-Cath© 18G in polyethylene and 8 cm long catheter. RESULTS: We enrolled 53 consecutive patients, reaching 769 catheter days. The procedure was performed without immediate complications in 37 patients out of 53 (69.8%). In 14 patients (26.4%), we observed a local hematoma (no one led to a failure or early removal of the device) and in two patients (3.7%) was not possible to draw blood. The average catheter dwell time was 14.5 days, from 3 to 41 days. In 42 patients (79.2%), the device was removed at the end of use. In 11 patients out of 53 (20.8%), the device was removed early due to complications: seven accidental removals, one obstruction, two vein thrombosis, and one superficial thrombophlebitis. CONCLUSIONS: The ultrasound-guided implantation of an 18G LPC in COVID19 patients, regardless of the state of their venous heritage, would seem to be an excellent strategy for these patients, reducing the number of venipunctures and CVC implantation, as well as allowing multiple and high pressure (contrast) infusions.

ABSTRACT

We report a case of primary malposition of a PICC inserted by guidewire replacement in the emergency room. Intraprocedural tip location by intracavitary electrocardiography was not feasible because the patient had atrial fibrillation; intraprocedural tip location by ultrasound (using the so-called "bubble test") showed that the tip was not in the superior vena cava or in the right atrium. A post-procedural chest X-ray confirmed the malposition but could not precise the location of the tip. A CT scan (scheduled for other purposes) finally visualized the tip in a very unusual location, the left pericardiophrenic vein.

ABSTRACT

INTRODUCTION: A serious complication associated with Central Venous Access Device (CVAD) is infection because of bacterial contamination, either by the extra-luminal or by the intra-luminal route.We evaluated the efficacy, the safety, and the cost-effectiveness of two strategies for non-inferiority in controlling bacterial colonization of the exit-site of Peripherally-Inserted Central Catheters (PICC). METHODS: After PICC placement, a skin swab of the exit site was taken and cultured. In group A the exit site was sealed with N-butyl-cyanoacrylate glue, while in group B a chlorhexidine-releasing sponge dressing was applied. A second skin culture was taken at day 7. RESULTS: A total of 51 patients were enrolled in each group. In 42 patients the second skin culture was not performed because of 20 patients were lost at follow-up or deceased and in 22 patients the dressing needed to be changed early, because of local bleeding (13 cases, in group B) or because of dressing detachment (four in group A and five in group B). The microbiological study was completed in 36 patients in group A and 24 in group B. No microorganisms were isolated in any patient. CONCLUSIONS: Both strategies were effective in controlling bacterial colonization. Glue was effective in reducing local bleeding, and it was more cost-effective than sponge dressing. During the first week, when local bleeding and bacterial colonization must be prevented, glue might be more appropriate than chlorhexidine-releasing dressing; after the first week chlorhexidine-releasing dressing might be preferable, considering that the safety of glue application on the skin for prolonged periods is still questionable.

ABSTRACT

Drug abuse (cannabis, cocaine, opiates, and synthetic drugs) is an increasing phenomenon, especially in the younger population, thus leading to more cases of intoxication requiring evaluation in the emergency department and subsequent hospitalization. In 2017, 34.2% of students reported having used an illegal psychoactive substance in their lifetime, while 26% reported having done so over the past year. We made a review about the effectiveness of the role of the temporary observation unit in the emergency department to improve management of acute drugs intoxication. We checked medical literature from the last 10 years (2009-2019). The following electronic databases were systematically searched: MEDLINE-PubMed, Web of Science, Scopus, and the Cochrane Central Register of Controlled Trials. Then, a systematic review was carried out according to the Preferred Reporting Items for Systematic Review standards. Intoxicated patients usually display a favorable medical course, few diagnostic and therapeutic interventions, a short stay in the hospital, and, when hospitalization is needed, semi-intensive therapy is a feasible solution; therefore, intoxicated patients are ideal candidates for a temporary observation unit. The emergency department is very important to manage intoxicated patients; however, the hospitalization of these patients is often not necessary.

ABSTRACT

Lung ultrasound (LUS) has recently been advocated as an accurate tool to diagnose coronavirus disease 2019 (COVID-19) pneumonia. However, reports on its use are based mainly on hypothesis studies, case reports or small retrospective case series, while the prognostic role of LUS in COVID-19 patients has not yet been established. We conducted a prospective study aimed at assessing the ability of LUS to predict mortality and intensive care unit admission of COVID-19 patients evaluated in a tertiary level emergency department. Patients in our sample had a median of 6 lung areas with pathologic findings (inter-quartile range [IQR]: 6, range: 0-14), defined as a score different from 0. The median rate of lung areas involved was 71% (IQR: 64%, range: 0-100), while the median average score was 1.14 (IQR: 0.93, range: 0-3). A higher rate of pathologic lung areas and a higher average score were significantly associated with death, with an estimated difference of 40.5% (95% confidence interval [CI]: 4%-68%, p = 0.01) and of 0.47 (95% CI: 0.06-0.93, p = 0.02), respectively. Similarly, the same parameters were associated with a significantly higher risk of intensive care unit admission with estimated differences of 29% (95% CI: 8%-50%, p = 0.008) and 0.47 (95% CI: 0.05-0.93, p = 0.02), respectively. Our study indicates that LUS is able to detect COVID-19 pneumonia and to predict, during the first evaluation in the emergency department, patients at risk for intensive care unit admission and death.

ABSTRACT

BACKGROUND: "Difficult intravenous access" patients represent a challenge within an emergency department as they often require many attempts to insert a peripheral short cannula in the emergency room or during the whole hospitalization. This can lead to many problems in terms of patient discomfort, increase of cost, and prolonged treatment time. OBJECTIVES: This study aimed to reduce the number of attempts needed for a short-cannula insertion or preventing insertion of a central vascular access by placing an ultrasound-guided long cannula during the emergency department visit. MATERIAL AND METHODS: The insertion of mini-midline was monitored within an emergency room in 50 patients considered difficult intravenous access patients, who failed two attempts at peripheral venous access insertion and/or required the use of an alternative vascular device. RESULTS: A total of 46 patients out of 50 were monitored. In 38 (82%) patients, the device was removed due to the end of the indication, and in six of them, it was replaced by a central venous catheter. Two devices were left inside even after discharge and were then removed at the end of indication. In eight (17%) patients, the device was removed due to accidental removal (4) and malfunction (4). In all the cases, the average duration of the insertion procedure was 10 min. The mean dwell time accounted to 7 and 9 days. CONCLUSION: The insertion of a mini-midline as part of the first emergency room visit in selected patients is a rapid, safe, and cost-effective procedure, which can provide the patient with stable venous access during the all hospitalization time.

ABSTRACT

INTRODUCTION: Well recognized guidelines are available for the use of cranial computed tomography (CCT) in traumatic patients, while no definitely accepted standards exists to for CCT in patients without history of head injury. The aim of this study is to propose an easy clinical score to stratify the need of CCT in emergency department (ED) patients with suspect non-traumatic intracranial pathology. METHODS: We retrospectively evaluated patients presenting to the ED for neurological deficit, postural instability, acute headache, altered mental status, seizures, confusion, dizziness, vertigo, syncope, and pre-syncope. We build a score for positive CCT prediction by using a logistic regression model on clinical factors significant at univariate analysis. The score was validated on a population of prospectively observed patients. RESULTS: We reviewed clinical data of 1156 patients; positivity of CCT was 15.2%. Persistent neurological deficit, new onset acute headache, seizures and/or altered state of consciousness, and transient neurological disorders were independent predictors of positive CCT. We observed 508 patients in a validation prospective cohort; CCT was positive in 11.3%. Our score performed well in validation population with a ROC AUC of 0.787 (CI 95% 0.748-0.822). Avoiding CT in score 0 patients would have saved 82 (16.2%) exams. No patients with score 0 had a positive CCT findings; score sensitivity was 100.0 (CI 95% 93.7-100.0). CONCLUSIONS: A score for risk stratification of patients with suspect of intra-cranial pathology could reduce CT request in ED, avoiding a significant number of CCT while minimizing the risk of missing positive results.

ABSTRACT

Somatic pain is one of the most frequent symptoms reported by patients presenting to the emergency department (ED), but, in spite of this, it is very often underestimated and under-treated. Moreover, pain-killers prescriptions are usually related to the medical examination, leading to a delay in its administration, thus worsening the patient's quality of life. With our study, we want to define and validate a systematic and homogeneous approach to analgesic drugs administration, testing a new therapeutic algorithm in terms of earliness, safety, and efficacy. 442 consecutive patients who accessed our ED for any kind of somatic pain were enrolled, and then randomly divided into two groups: group A follow the normal process of access to pain-control drugs, and group B follow our SUPER algorithm for early administration of drugs to relieve pain directly from triage. We excluded from the study, patients with abdominal pain referred to the surgeon, patients with headache, recent history of trauma, history of drug allergies, and life-threatening conditions or lack of cooperation. Drugs used in the study were those available in our ED, such as paracetamol, paracetamol/codeine, ketorolac-tromethamine, and tramadol-hydrochloride. Pain level, risk factors, indication, and contraindication of each drug were taken into account in our SUPER algorithm for a rapid and safe administration of it. The Verbal Numeric Scale (VNS) and the Visual Analog Scale (VAS) were used to verify the patient's health and perception of it. Only 59 patient from group A (27.1 %) received analgesic therapy (at the time of the medical examination) compared to 181 patients (100 %) of group B (p < 0.001). Group B patients, received analgesic therapy 76 min before group A subjects (p < 0.01), resulting in a significant lower VNS (7.31 ± 1.68 vs 4.75 ± 2.3; p < 0.001), and a superior VAS after discharge (54.43 ± 22.16 vs 61.30 ± 19.13; p < 0.001) compared to group A subjects. No significant differences concerning side effects were observed between group A and group B patients. Early administration of a pain-control therapy directly from triage is safe and effective, and significantly improves patients perceptions of their own health.

ABSTRACT

INTRODUCTION: Hyperthyroidism is a relative uncommon but important cause of atrial fibrillation. The aim of this study was to investigate the utility of routine thyroid-stimulating hormone (TSH) determination in the emergency department (ED) in patients presenting to the ED with stable, new-onset atrial fibrillation. We derive a set of clinical criteria in which TSH is likely to be normal and therefore thyroid function evaluation deferrable to a different time from ED visit. METHODS: Cross-sectional observational study in a university hospital. Thyroid-stimulating hormone was measured in all patients admitted to the ED observational unit for new-onset atrial fibrillation in a 30 consecutive months' period. Patients' clinical characteristics and treatment received in the ED were recorded. Recursive partitioning analysis technique was used to determine which predictors were associated with a TSH level less than 0.35 µIU/mL. RESULTS: Of 433 patients enrolled, 47 (10.8%) had a low TSH. Thyroid-stimulating hormone highly correlated with FT3 and FT4 levels (P < .001) confirming its good predictive value as screening tool. Recursive partitioning analysis showed that previous thyroid disease (P < .01), stroke/transient ischemic attack (P < .01), and hypertension (P = .10) were associated with low TSH. The final model had sensitivity of 93% and specificity of 31%, corresponding to a negative likelihood ratio of 0.02 (0.01-0.07). CONCLUSION: Hyperthyroidism is present in nearly 10% of new-onset atrial fibrillation. Although thyroid function screening is recommended in all patients, a simple model that included previous thyroid disease, stroke, and hypertension might help to identify those patients at high risk (low TSH) in the ED.

ABSTRACT

OBJECTIVE: To detect the clinical use of N-terminal pro B-type natriuretic peptide (NT-proBNP) values for predicting cardioversion in a new onset atrial fibrillation (AF) in the emergency department. METHODS: NT-proBNP was measured in 200 patients admitted to the emergency department, in the observational unit with primary diagnosis of a new onset AF (<2 weeks). Cohort was divided into rate-control and rhythm-control groups according to the strategy used by the admitting physician. Patients treated with electric cardioversion were excluded. Primary endpoint was conversion to sinus rhythm during hospital admission. RESULTS: In rhythm and rate controls, NT-proBNP was lower in patients who restored sinus rhythm (P<0.001). Same result was observed even when logistic regression was used to adjust for differences at baseline clinical characteristics. NT-proBNP of less than 450 pg/ml was associated with cardioversion in both the groups (likelihood ratio of 0.19 for rate control, and 0.27 for rhythm control) whereas a value of more than 1800 pg/ml was associated with persistent AF at discharge (likelihood ratio of 2.02 and 2.01, respectively). CONCLUSION: In the acute setting of a new onset AF, NT-proBNP seems to predict cardioversion in rate-control and rhythm-control strategies when it is less than 450 pg/ml or more than 1800 pg/ml. In this ranges of values it might help to allocate resources and plan for patient admission and further management. There is a grey area (450-1800 pg/ml) in which NT-proBNP did not seem to be clinically useful.
