Lactate Profile Assessment-A Good Predictor of Prognosis in Patients with COVID-19 and Septic Shock Requiring Continuous Renal Therapy.

INTRODUCTION: Lactate is a useful prognostic marker, as its level increases in hypoxic tissue and/or during accelerated aerobic glycolysis due to excessive beta-adrenergic stimulation and decreased lactate clearance. The Surviving Sepsis Campaign Bundle 2018 Update suggests premeasurement of lactate within 2-4 h so that physicians perform, assist, administer, and introduce lactate-guided resuscitation to reduce mortality due to sepsis. METHODS: A total of 108 patients with septic shock who underwent continuous renal replacement therapy (CRRT) for acute kidney injury were enrolled in this observational study. Demographic, clinical, and laboratory data were collected, and patients were divided into two groups: survivors and non-survivors. RESULTS: Multivariate analysis demonstrated that lactate levels at 24 h after initiation of CRRT treatment, but not lactate levels at intensive care unit (ICU) admission, were associated with mortality. Lactate clearance was associated with lower mortality among the survivors (OR = 0.140) at 6 h after ICU admission and late mortality (OR = 0.260) after 24 h. The area under the ROC curves for mortality was 0.682 for initial lactate; 0.797 for lactate at 24 h; and 0.816 for lactate clearance at 24 h. CONCLUSIONS: Our result reinforces that the determination of lactate dynamics represents a good predictor for mortality, and serial lactate measurements may be more useful prognostic markers than initial lactate in patients with septic shock.

Code Stroke Alert: Focus on Emergency Department Time Targets and Impact on Door-to-Needle Time across Day and Night Shifts.

BACKGROUND AND OBJECTIVES: To minimize stroke-related deaths and maximize the likelihood of cerebral reperfusion, medical professionals developed the "code stroke" emergency protocol, which allows for the prompt evaluation of patients with acute ischemic stroke symptoms in pre-hospital care and the emergency department (ED). This research will outline our experience in implementing the stroke code protocol for acute ischemic stroke patients and its impact on door-to-needle time (DTN) in the ED. METHODS: Our study included patients with a "code stroke alert" upon arrival at the emergency department. The final sample of this study consisted of 258 patients eligible for intravenous (IV) thrombolysis with an onset-to-door time < 4.5 h. ED admissions were categorized into two distinct groups: "day shift" (from 8 a.m. to 8 p.m.) (n = 178) and "night shift" (from 8 p.m. to 8 a.m.) (n = 80) groups. RESULTS: An analysis of ED time targets showed an increased median during the day shift for onset-to-ED door time of 310 min (IQR, 190-340 min), for door-to-physician (emergency medicine doctor) time of 5 min (IQR, 3-9 min), for door-to-physician (emergency medicine doctor) time of 5 min (IQR, 3-9 min), and for door-to-physician (neurologist) time of 7 min (IQR, 5-10 min), also during the day shift. During the night shift, an increased median was found for door-to-CT time of 21 min (IQR, 16.75-23 min), for door-to-CT results of 40 min (IQR, 38-43 min), and for door-to-needle time of 57.5 min (IQR, 46.25-60 min). Astonishingly, only 17.83% (n = 46) of these patients received intravenous thrombolysis, and the proportion of patients with thrombolysis was significantly higher during the night shift (p = 0.044). A logistic regression analysis considering the door-to-needle time (minutes) as the dependent variable demonstrated that onset-to-ED time (p < 0.001) and door-to-physician (emergency medicine physicians) time (p = 0.021) are predictors for performing thrombolysis in our study. CONCLUSIONS: This study identified higher door-to-CT and door-to-emergency medicine physician times associated with an increased DTN, highlighting further opportunities to improve acute stroke care in the emergency department. Further, door-to-CT and door-to-CT results showed statistically significant increases during the night shift.

Risk Assessment of Venous Thromboembolism among Septic Shock Patients: Single versus Concurrent Insertion of Central Venous Catheters.

Background and Objectives: Thrombosis is a serious complication experienced by some hospitalized patients. While concurrent placement of two catheters (CVCs) in the same central vein offers several benefits in clinical settings, we aimed to investigate the role of this procedure in relation to the risk of thrombosis. Materials and Methods: Over a two-year retrospective analysis, we examined 114 patients with septic shock caused by a pulmonary infection, who underwent the insertion of one or more central lines into a central vein during their ICU stay. Logistic regression models were employed to assess the correlation between the Caprini risk score, the placement of two CVCs in the same vein, COVID-19 infection and the risk of venous thromboembolism (VTE). Results: In total, 53% of the patients underwent the concurrent insertion of two CVCs. The placement of two CVCs in the same vein appears to elevate the VTE risk by 2.5 times (95% CI: 1.03-6.12). Logistic regression analysis indicated that hemodialysis catheters amplify the VTE risk by nearly five times, even when accounting for a series of factors (95% CI: 1.86-12.31). Conclusions: Our study suggests that the elevated risk of VTE is likely associated with the insertion of the hemodialysis catheters rather than solely the presence of two concurrent catheters.

Lactate Levels and Clearance: Key Predictors of Prognosis for COVID-19 and Non-COVID-19 Septic Shock Patients in the Emergency Department.

BACKGROUND: This investigation assesses the prognostic value of lactate levels and their clearance in septic shock patients, particularly emphasizing the comparative analysis between COVID-19 and non-COVID-19 patients in the emergency department. This study aims to elucidate the unique prognostic implications of lactate dynamics in these distinct patient groups, thereby enhancing the management of septic shock. METHODS: An observational prospective study was conducted, enrolling 114 septic shock patients from the Emergency County Hospital Resita, Romania, categorizing them into COVID-19 and non-COVID-19 groups to examine their initial lactate levels, clearance rates, and their correlation with patient outcomes. RESULTS: This study identified significant differences in the initial lactate levels and clearance rates between the two groups, indicating higher initial lactate levels and slower clearance rates in COVID-19 patients. Survivors demonstrated significantly lower initial lactate levels (1.5 ± 0.4 mmol/L) and higher lactate clearance rates (33 ± 15%) compared to non-survivors (2.5 ± 0.5 mmol/L and 24 ± 9%, respectively; lactate levels p = 0.001, clearance rates p = 0.002). CONCLUSIONS: Lactate monitoring, particularly clearance rates, is crucial in the prognostic assessment of septic shock patients. These findings highlight the need for targeted interventions in COVID-19 patients to improve outcomes, underscoring lactate dynamics as a vital component of septic shock management in differing patient populations.

Cardiac Arrest and Complete Heart Block: Complications after Electrical Cardioversion for Unstable Supraventricular Tachycardia in the Emergency Department.

Synchronous electrical cardioversion is a relatively common procedure in the emergency department (ED), often performed for unstable supraventricular tachycardia (SVT) or unstable ventricular tachycardia (VT). However, it is also used for stable cases resistant to drug therapy, which carries a risk of deterioration. In addition to the inherent risks linked with procedural sedation, there is a possibility of malignant arrhythmias or bradycardia, which could potentially result in cardiac arrest following this procedure. Here, we present a case of complete heart block unresponsive to transcutaneous pacing and positive inotropic and chronotropic drugs for 90 min, resulting in multiple cardiac arrests. The repositioning of the transcutaneous cardio-stimulation electrodes, one of them placed in the left latero-sternal position and the other at the level of the apex, led to immediate stabilization of the patient. The extubation of the patient was performed the following day, with full recovery and discharge within 7 days after the insertion of a permanent pacemaker.

The Learning Experience of Romanian Medical Students During the Online Teaching Imposed by the COVID-19 Pandemic.

Introduction: The COVID-19 pandemic has disrupted many aspects of society, including medical education. In response to the pandemic, Romanian medical schools and universities have turned to online learning as a means of continuing instruction while maintaining social distancing protocols. While online learning in medical education was utilized prior to the pandemic, its widespread adoption has brought both challenges and opportunities to the field. The purpose of this study was to assess medical students' perception towards implementing E-learning during COVID 19 pandemic. Material and Methods: This cross-sectional multicentric study comprised 611 medical students from several medical university centers from Romania. A self-developed questionnaire was online applied between January and March 2021 and used for the evaluation and analysis of perceived changes in teaching before and during the COVID-19 pandemic. Results: Most students (n = 71.5%) considered that the pandemic had an overall negative impact on their professional development. A significant negative correlation (p < 0.01, for all), was observed between during COVID-19 pandemic and the level of medical training, motivation to learn, and level of self-confidence. Conclusion: The shift to online learning during the pandemic decreased the psychological and professional development of medical students, resulting in a low perception of self-confidence, motivation, and practical involvement. However, there are many benefits brought by the use of electronic technologies for medical education both in Romania and in the world. These benefits should be systematically evaluated, and effective strategies should be developed to permanently improve the e-learning methods of these students.

Emergency Department Time Targets for Interhospital Transfer of Patients with Acute Ischemic Stroke.

Background and objectives: Although the intravenous tissue plasminogen activator (rt-PA) has been shown to be effective in the treatment of acute ischemic stroke (AIS), only a small proportion of stroke patients receive this drug. The low administration rate is mainly due to the delayed presentation of patients to the emergency department (ED) or the lack of a stroke team/unit in most of the hospitals. Thus, the aim of this study is to analyze ED time targets and the rate of rt-PA intravenous administration after the initial admission of patients with AIS in an ED from a traditional healthcare center (without a neurologist or stroke team/unit). Methods: To analyze which factors influence the administration of rt-PA, we split the general sample (n = 202) into two groups: group No rt-PA (n = 137) and group rt-PA (n = 65). This is based on the performing or no intravenous thrombolysis. Results: Analyzing ED time targets for all samples, we found that the median onset-to-ED door time was 180 min (IQR, 120-217.5 min), door-to-physician time was 4 min (IQR, 3-7 min), door-to-CT time was 52 min (IQR, 48-55 min), and door-in-door-out time was 61 min (IQR, 59-65 min). ED time targets such as door-to-physician time (p = 0.245), door-to-CT time (p = 0.219), door-in-door-out time (p = 0.24), NIHSS at admission to the Neurology department (p = 0.405), or NIHSS after 24 h (p = 0.9) did not have a statistically significant effect on the administration or no rt-PA treatment in patients included in our study. Only the highest door-to-CT time was statistically significantly correlated with the death outcome. Conclusion: In our study, the iv rt-PA administration rate was 32.18%. A statistically significant correlation between the highest door-to-CT time and death outcome was found.

Risk Factors, Characteristics, and Outcome in Non-Ventilated Patients with Spontaneous Pneumothorax or Pneumomediastinum Associated with SARS-CoV-2 Infection.

BACKGROUND AND OBJECTIVES: Spontaneous pneumothorax (SP) and spontaneous pneumomediastinum (SPM) have frequently been cited as complications associated with coronavirus disease 2019 (COVID-19) pneumonia, with especially poor prognosis in mechanically ventilated patients. The current literature is controversial regarding the potential risk factors for developing SP or SPM (SP-SPM) in non-ventilated COVID-19 patients. Our research addressed a twofold objective: (a) to investigate the characteristics of patients with SP-SPM (both with and without COVID-19) and compare them to patients with sole COVID-19; (b) to quantify the risk of in-hospital mortality associated with SP-SPM and COVID-19. PATIENTS AND METHODS: A retrospective case-control study was conducted in the emergency departments (ED) of two tertiary hospitals in Timisoara, Romania, over one year (1st April 2020‒31st March 2021; 64,845 records in total) and 70 cases of SP-SPM were identified (both SARS-CoV-2 positives and negatives). The control group comprised COVID-19 patients with no SP-SPM, included at a 2:1 ratio. Logistic regression was employed to quantify the in-hospital mortality risk associated with age, SP-SPM, and COVID-19. RESULTS: SP-SPM and COVID-19 were connected with prolonged hospitalization, a higher percentage of intensive care admission, and a higher mortality. SP-SPM increased the odds of death by almost four times in patients of the same age, gender, smoking status, and SARS-CoV-2 infection: OR = 3.758, 95% CI (1.443-9.792). Each additional year of age added 9.4% to the mortality risk: OR = 1.094, 95% CI (1.054-1.135). CONCLUSION: ED physicians should acknowledge these potential risks when attending COVID-19 patients with SP-SPM.
