RESUMO
Object: Effective triage of febrile patients in the emergency department is crucial during times of overcrowding to prioritize care and allocate resources, especially during pandemics. However, available triage tools often require laboratory data and lack accuracy. We aimed to develop a simple and accurate triage tool for febrile patients by modifying the qSOFA score. Methods: We retrospectively analyzed data from 7,303 febrile patients and created modified versions of qSOFA using factors identified through multivariable analysis. The performance of these modified qSOFAs in predicting in hospital mortality and intensive care unit (ICU) admission was compared using the area under the receiver operating characteristic curve (AUROC). Results: Through multivariable analysis, the identified factors were age (A), male sex (M), SpO2 (S), and lactate levels (L). The AUROCs of ASqSOFA (for in-hospital mortality: 0.812; 95% CI: 0.789-0.835, for ICU admission: 0.794; 95% CI: 0.771-0.817), which included age and SpO2 with qSOFA, were simple and not inferior to other more complex models (e.g., ASMqSOFA, ASLqSOFA, and ASMLqSOFA). ASqSOFA also displayed significantly higher AUROC than other triage scales, such as the modified early warning score and Korean triage and acuity scale. The optimal cut-off score of ASqSOFA for the outcome was 2 and the score for redistribution to a lower-level emergency department was 0. Conclusion: We demonstrated that ASqSOFA can be employed as a simple and efficient triage tool for emergency febrile patients to aid in resource distribution during overcrowding. It may also be applicable in pre-hospital settings for febrile patient triage.
RESUMO
Surgical debridement is an essential step in treating complex facial lacerations (CFL). As the CFL severity increases, conventional surgical debridement (CSD) of wound edges becomes difficult and may be insufficient. Because the severity and shape of each CFL vary, it is necessary to tailor the customized pre-excisional design, that is, tailored surgical debridement (TSD), for each case before performing surgical debridement. The use of TSD can enable effective debridement of CFL with higher severity. This study aimed to compare the cosmetic outcomes and complication incidence of CSD versus TSD according to CFL severity. In this retrospective observational study, eligible patients with CFL who visited the emergency department between August 2020 and December 2021 were examined. CFL severity was graded as Grades I and II. The outcomes of CSD and TSD were compared using the scar cosmesis assessment and rating (SCAR) scale, wherein a good cosmetic outcome was defined as a SCAR score ofâ ≤â 2. The percentage of good cosmetic outcomes between the 2 groups was compared. The SCAR score and percentage of good cosmetic outcomes between the 2 groups were compared overall and by severity. For analyzing complication incidence, asymmetry, infection, and dehiscence incidence were compared. In total, 252 patients were enrolled [121 (48.0%) CSD and 131 (52.0%) TSD]. The median SCAR scores were 3 (1-5) and 1 (0-2) in all enrolled patients (Pâ <â .001), 2 (0-4), and 1 (0-1) in Grade I patients (Pâ <â .01), and 5 (4-6) and 1 (1-2) in Grade II patients (Pâ <â .001) in the CSD and TSD groups, respectively. The percentage of good cosmetic outcomes was 46.3% and 84.0% overall (Pâ <â .001), 59.6% and 85.0% in Grade I patients (Pâ <â .01), and 9.4% and 83.5% in Grade II patients (Pâ <â .001) in the CSD and TSD groups, respectively. The incidence of complications was significantly higher in the CSD group than in the TSD group, but this was limited to asymmetry. No significant difference was noted in infection or dehiscence. Compared with CSD, TSD can lead to an objectively good cosmetic prognosis at higher CFL severity and can reduce facial asymmetry occurrence.

PURPOSE: To verify the role of lactate dehydrogenase to albumin (LDH/ALB) ratio as an independent prognostic factor for mortality due to the lower respiratory tract infection (LRTI) in the emergency department (ED). METHODS: We reviewed the electronic medical records of patients who were admitted to the ED for the management of LRTI between January 2018 and December 2020. Initial vital signs, laboratory data, and patient severity scores in the ED were collected. The LDH/ALB ratio was compared to other albumin-based ratios (blood urea nitrogen to albumin ratio, C-reactive protein to albumin ratio, and lactate to albumin ratio) and severity scales (pneumonia severity index, modified early warning score, CURB-65 scores), which are being used as prognostic factors for in-hospital mortality. Multivariable logistic regression was performed to identify independent risk factors. RESULTS: The LDH/ALB ratio was higher in the non-survivor group than in the survivor group (median [interquartile range]: 217.6 [160.3;312.0] vs. 126.4 [100.3;165.1], p < 0.001). In the comparison of the area under the receiver operating characteristic curve (AUC) for predicting in-hospital mortality, the AUC of the LDH/ALB ratio (0.808, 95% confidence interval: 0.757-0.842, p < 0.001) was wider than other albumin-based ratios and severity scales, except the blood urea nitrogen to albumin ratio. In the multivariable logistic regression analysis, the LDH/ALB ratio independently affected in-hospital mortality. CONCLUSION: The LDH/ALB ratio may serve as an independent prognostic factor for in-hospital mortality in patients with LRTI.

ABSTRACT: This study was performed to verify whether lactate dehydrogenase to albumin (LDH/ALB) ratio could be used as an independent prognostic factor in patients with severe infection requiring intensive care.We reviewed electronic medical records of patients hospitalized to the intensive care unit via the emergency department with a diagnosis of infection between January 2014 and December 2019. From the collected data, ALB-based ratios (LDH/ALB, blood urea nitrogen to albumin, C-reactive protein to albumin, and lactate to albumin ratios) and some severity scores (modified early warning score, mortality in emergency department sepsis score [MEDS], and Acute Physiology And Chronic Health Evaluation II [APACHE II] score) were calculated. LDH/ALB ratio for predicting the in-hospital mortality was compared with other ALB-based ratios and severity scales by univariable and receiver-operating characteristics curve analysis. Modified severity scores by LDH/ALB ratio and multivariable logistic regression were used to verify the independence and usefulness of the LDH/ALB ratio.The median LDH/ALB ratio was higher in non-survivors than survivors (166.9 [interquartile range: 127.2-233.1] vs 214.7 [interquartile range: 160.2-309.7], Pâ<â.001). The area under the receiver-operating characteristics curve of the LDH/ALB ratio (0.642, 95% confidence interval: 0.602-0.681, Pâ<â.001) was not lower than that of other ALB-based ratios and severity scores. From multivariable logistic regression, LDH/ALB ratio was independently associated with in-hospital mortality (odds ratioâ=â1.001, 95% confidence interval: 1.000-1.002, Pâ=â.047). Area under the receiver-operating characteristics curves of MEDS and APACHE II scores were improved by modification with LDH/ALB ratio (MEDS: 0.643 vs 0.680, Pâ<â.001; APACHE II score: 0.675 vs 0.700, Pâ=â.003).LDH/ALB ratio may be useful as the prognostic factor in patients with severe infection requiring intensive care.

ABSTRACT: This study aimed to evaluate times for measuring serum lactate dehydrogenase levels (SLLs) to predict neurological prognosis among out-of-hospital cardiac arrest (OHCA) survivors.This retrospective study examined patients who experienced OHCA treated with targeted temperature management (TTM). The SLLs were evaluated at the return of spontaneous circulation (ROSC) and at 24, 48, and 72âhours later. Neurological outcomes after 3âmonths were evaluated for relationships with the SLL measurement times.A total of 95 comatose patients with OHCA were treated using TTM. Seventy three patients were considered eligible, including 31 patients (42%) who experienced good neurological outcomes. There were significant differences between the good and poor outcome groups at most time points (Pâ<â.001), except for ROSC (Pâ=â.06). The ROSC measurement had a lower area under the receiver operating characteristic curve (AUC: 0.631, 95% confidence interval [CI]: 0.502-0.761) than at 48âhours (AUC: 0.830, 95% CI: 0.736-0.924), at 24âhours (AUC: 0.786, 95% CI: 0.681-0.892), and at 72âhours (AUC: 0.821, 95% CI: 0.724-0.919).A higher SLL seemingly predicted poor neurological outcomes, with good prognostic values at 48âhours and 72âhours. Prospective studies should be conducted to confirm these results.

ABSTRACT: This retrospective cohort study aimed to compare the effectiveness of conventional treatment and ultra-early application of negative pressure wound therapy (NPWT) in patients with snakebites.Patients who visited the emergency department within 24âhours after a snakebite were assigned to the non- NPWT or NPWT group. Swelling resolution time and rates of necrosis, infection, and operations were compared between the 2 groups. The Stony Brook Scar Evaluation Scale was used to measure short- and long-term wound healing results.Among the included 61 patients, the swelling resolution time was significantly shorter in the NPWT group than in non- NPWT group (Pâ=â.010). The NPWT group showed lower necrosis (4.3% versus 36.8%; Pâ=â.003) and infection (13.2% and 4.3%; Pâ=â.258) rates than the non- NPWT group. The median Stony Brook Scar Evaluation Scale scores were higher in the NPWT group than in the non- NPWT group (P<â.001).These findings suggest that ultra-early application of NPWT reduces edema, promotes wound healing, and prevents necrosis in patients with snakebites.

We aimed to verify whether slow heart rate (HR) is associated with neurologic outcome and the factors that can contribute to the development of bradycardia in out-of-hospital cardiac arrest (OHCA) survivors who underwent targeted temperature management (TTM). We extracted the data of comatose adult OHCA survivors who underwent TTM between October 2015 and December 2018 from the prospective multicenter registry. Data on HR recorded every 6 hours within 72 hours after return of spontaneous circulation and calculated minimal, mean, and maximal HR and time to the lowest HR were obtained. HR <50 bpm was defined as bradycardia. The primary outcome was a 6-month neurologic outcome based on Pittsburgh-Glasgow Cerebral Performance Category Scale. Of the 814 included patients, 508 (62.4%) had poor neurologic outcome and 197 (24.2%) had bradycardia. Bradycardia (odds ratio [OR], 0.574; 95% confidence interval [CI], 0.362-0.192), minimal HR (OR, 1.023; 95% CI, 1.008-1.037), and mean HR (OR, 1.016; 95% CI, 1.002-1.030) were independently associated with poor neurologic outcome, but not maximal HR and time to the lowest HR. Preexisting arrhythmia (OR, 2.067; 95% CI, 1.037-4.118), renal disease (OR, 2.028; 95% CI, 1.153-3.567), cardiac etiology (OR, 1.526; 95% CI, 1.045-2.228), downtime (OR, 0.985; 95% CI, 0.974-0.996), and serum lactate levels (OR, 0.936; 95% CI, 0.900-0.974) were independently associated with bradycardia. Bradycardia and decreased mean and minimal HR were independently associated with good neurologic outcomes. Bradycardia was associated with preexisting arrhythmia, renal disease, cardiac etiology, shorter downtime, and lower serum lactate level.

AIM: This study examined whether the presence of cortical necrosis (CN) on ultra-early diffusion-weighted imaging (DWI) and the severity of cytotoxic oedema (CytE) with cerebral oedema (CbrE), measured using quantitative analysis of apparent diffusion coefficient (ADC), could predict neurological outcomes before targeted temperature management in out-of-hospital cardiac arrest survivors (OHCAs). METHODS: In this retrospective study, the first DWI with ADC scans was performed within 6â¯h; the second was obtained between 72 and 96â¯h after return of spontaneous circulation. The primary outcome was neurological outcomes at 6 months after OHCA. The % voxels of ADC value (PV) was calculated; CbrE and CytE values wereâ¯>â¯orâ¯<â¯than 650-6â¯mm2/s, respectively. The best performance PV was obtained from CytE (thld-CytE) and CbrE values (thld-CbrE). Prognostic performances of CN, thld-CytE, thld-CbrE, and converted scores were calculated in combination. The changes in DWI findings and the difference between the PV (ΔPV) from the first and second DWI were analysed. RESULTS: Thirty-six patients were included. CN (area under receiver operating characteristic curve [AUC]â¯=â¯0.800), thld-CytE (PV420; AUCâ¯=â¯0.730), and thld-CbrE (PV1090; AUCâ¯=â¯0.775) showed meaningful performance, and the combined score showed best performance for poor outcome prediction (AUCâ¯=â¯0.956). DWI findings of CN patients was worse at the second DWI. ΔPV significantly increased in the poor outcome group, CN patients, and the group including both, thld-CytE and thld-CbrE. CONCLUSIONS: In OHCAs, ultra-early DWI with ADC could successfully predict poor neurological outcomes by combining scores of CN, thld-CytE, and thld-CbrE.

We aimed to compare the relationship of mean arterial pressure (MAP) and intracranial pressure (ICP) to predict the neurological prognosis in cardiac arrest (CA) survivors. We retrospectively examined out-of-hospital CA patients treated with targeted temperature management. ICP was measured using cerebrospinal fluid (CSF) pressure, whereas MAP was measured as blood pressure monitored through the radial or femoral artery during CSF pressure measurement. Primary outcome was 6-month neurological outcome. Of 92 enrolled patients, the favorable outcome group comprised 31 (34%) patients. The median and interquartile range of MAP were significantly higher and ICP was significantly lower in patients with favorable neurological outcomes than in those with unfavorable neurological outcomes (94.3 mmHg [80.0-105.3] vs. 82.0 mmHg [65.3-96.3], p = 0.021 and 9.4 mmHg [10.8-8.7] vs. 18.8 mmHg [20.0-15.7], p < 0.001, respectively). ICP showed the higher area under the receiver operating characteristic curve (area under curve [AUC] = 0.953, 95% confidence interval [CI] = 0.888-0.986) for neurological outcome prediction. MAP showed the lower AUC (0.648, 95% CI = 0.541-0.744). Higher accurate prognosis was predicted by ICP than MAP, and the prognostic performance was good. Prospective multicenter studies are required to confirm these results.

BACKGROUND: Metformin is commonly used for the treatment of type 2 diabetes mellitus. Renal insufficiency is one of the contraindications for its use. Inadvertent prescription in patients with renal insufficiency may lead to metformin-associated lactic acidosis (MALA), which is associated with a high risk of mortality. Consequently, the early recognition and management of MALA is essential. CASE REPORT: We present the case of a 68-year-old man who had reversible blindness resulting from severe lactic acidosis. On presentation, he was alert, oriented, and had no complaints except mild abdominal discomfort and blindness. He denied any history of trauma or drug abuse. The results of the laboratory studies showed severe metabolic acidosis with a high anion gap and increased levels of serum creatinine. There were no predisposing ocular or neurologic lesions that could have induced the blindness. Although the blood levels of methanol, ethanol, and metformin were not estimated, correction of acidosis and hemodialysis led to a complete recovery. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Rarely, transient blindness may occur in patients with fatal severe metabolic acidosis. Evaluation for the presence of metabolic acidosis and a detailed medical history are essential in the management of acute blindness in such patients.

PURPOSE: Brain swelling post-cardiac arrest may affect cerebrospinal fluid volume. We aimed to investigate the prognostic performance of the proportion of cerebrospinal fluid volume (pCSFV) using brain computed tomography (CT) in cardiac arrest survivors. MATERIALS AND METHODS: This retrospective multicentre study included adult comatose cardiac arrest survivors who underwent brain CT scan prior to target temperature management (TTM) from 2015 to 2016. Grey-to-white matter ratio (GWR) and pCSFV values were calculated. pCSFV analysis was performed using automated quantitative analysis programming. The primary outcome was a 6-month neurological outcome. RESULTS: Of 251 patients (median age, 57â¯years), 173 (68.9%) were male, 87 (34.7%) had a shockable rhythm, and 160 (63.7%) had unfavourable neurological outcomes. GWR but not pCSFV was significantly higher in terms of favourable neurological outcomes (pâ¯=â¯.015). pCSFV prognostic performances were similar to GWR, and were poor overall, (0.521; 95% confidence interval [CI], 0.446-0.694 vs. 0.515; 95% CI, 0.441-0.589). After adjusting for covariates, pCSFV but not GWR was independently associated with neurological outcome 6â¯months following cardiac arrest (pâ¯=â¯.049). CONCLUSION: pCSFV was independently associated with neurological outcome 6â¯months following cardiac arrest, however prognostic performance was not good.

PURPOSE: The technical factors which improve cosmetic outcomes and which need to be emphasized in education of junior residents have yet to be described. We compared cases in which suturing was performed by either junior emergency medicine residents or experts, in order to determine the focus of future education and training. METHODS: Wound registry data was reviewed and retrospectively analyzed from September 2015 to February 2016. Only patients who visited the emergency room with facial lacerations were enrolled, and their wound registry data sheets were reviewed. Practitioners were divided into junior resident and expert groups. We assessed the progress using the Stony Brook Scar Evaluation Scale (SBSES) 5-10â¯days following suturing. RESULTS: Sixty-six patients were enrolled; 43 (65.2%) were men. The median (interquartile range) cosmetic scores (SBSES scale) for suturing performed by junior residents or experts were 3 (2-4) and 5 (4-5), respectively (pâ¯=â¯0.001). The percentage of maximum scores for each SBSES category was significantly lower in the junior resident group than in the expert group for width (68% vs. 86%), hatch marks (68% vs. 93%), and overall appearance (41% vs. 80%) (all pâ¯<â¯0.001). CONCLUSIONS: There were significant differences in scar widths and hatch marks, which were attributable to the skill level of the practitioner who performed the suturing of facial lacerations. Junior residents should be educated about maintenance of proper tension, atraumatic technique, and performing appropriate trimming or debridement.

OBJECTIVE: Patients are often transported within the hospital, especially in cases of critical illness for which computed tomography (CT) is performed. Since increased transport time increases the risks of complications, reducing transport time is important for patient safety. This study aimed to evaluate the ability of our newly invented device, the Easy Tube Arrange Device (ETAD), to reduce transport time for CT evaluation in cases of critical illness. METHODS: This prospective randomized control study included 60 volunteers. Each participant arranged five or six intravenous fluid lines, monitoring lines (noninvasive blood pressure, electrocardiography, central venous pressure, arterial catheter), and therapeutic equipment (O2 supply device, Foley catheter) on a Resusci Anne mannequin. We measured transport time for the CT evaluation by using conventional and ETAD method. RESULTS: The median transport time for CT evaluation was 488.50 seconds (95% confidence interval [CI], 462.75 to 514.75) and, 503.50 seconds (95% CI, 489.50 to 526.75) with 5 and 6 fluid lines using the conventional method and 364.50 seconds (95% CI, 335.00 to 388.75), and 363.50 seconds (95% CI, 331.75 to 377.75) with ETAD (all P<0.001). The time differences were 131.50 (95% CI, 89.25 to 174.50) and 148.00 (95% CI, 116.00 to 177.75) (all P<0.001). CONCLUSION: The transport time for CT evaluation was reduced using the ETAD, which would be expected to reduce the complications that may occur during transport in cases of critical illness.
RESUMO
BACKGROUND: Cannulation of the great vessels is required for extracorporeal membrane oxygenation (ECMO). Currently, there is no guideline for optimal imaging modalities during percutaneous cannulation of ECMO. OBJECTIVE: The purpose of this study was to describe percutaneous cannulation guided by point-of-care ultrasound (POCUS) for ECMO and compare it with fluoroscopy and landmark guidance. METHODS: Three groups (POCUS-, fluoroscopy-, and landmark-guided) of percutaneous cannulation for ECMO were analyzed retrospectively in a tertiary academic hospital. In the POCUS-guided group, visual confirmation of guidewire and cannula by ultrasound in both the access and return cannula were essential for successful cannulation. Fluoroscopy- and landmark-guided groups were cannulated with the conventional technique. RESULTS: A total of 128 patients were treated by ECMO during the study period, of which 94 (73.4%) cases were venoarterial ECMO. This included 56 cases of extracorporeal cardiopulmonary resuscitation. Also, there were 30 (23.4%) cases of venovenous ECMO and 4 (3.1%) cases of venoarteriovenous ECMO. A total of 71 (55.5%) patients were cannulated under POCUS guidance, and 43 (33.6%) patients were cannulated under fluoroscopy guidance and 14 (10.9%) patients were cannulated by landmark guidance. No surgical cut downs were required. Misplacement of cannula occurred in 3 (2.3%) cases. All three occurred in the landmark-guided group. CONCLUSIONS: POCUS-guided cannulation is comparable to fluoroscopy-guided cannulation in terms of avoiding cannula misplacement. In our experience, POCUS-guided cannulation is a useful strategy over fluoroscopy- and landmark-guided cannulation during peripheral ECMO.

OBJECTIVE: Critically ill patients sometimes require transport to another location. Longer intra-hospital transport time increases the risk of hemodynamic instability and associated complications. Therefore, reducing intra-hospital transport time is critical. Our objective was to evaluate whether or not a new device the easy tube arrange device (ETAD) has the potential to reduce intra-hospital transport time of critically ill patients. METHODS: We enrolled volunteers for this prospective randomized controlled study. Each participant arranged four, five, and six fluid tubings, monitoring lines, and therapeutic equipment on a cardiopulmonary resuscitation training mannequin (Resusci Anne). The time required to arrange the fluid tubings for intra-hospital transport using two different methods was evaluated. RESULTS: The median time to arrange four, five, and six fluid tubings was 86.00 (76.50 to 98.50), 96.00 (86.00 to 113.00), and 115.50 (93.00 to 130.75) seconds, respectively, using the conventional method and 60.50 (52.50 to 72.75), 69.00 (57.75 to 80.80), and 72.50 (64.75 to 90.50) seconds using the ETAD (all P<0.001). The total duration (for preparing the basic setting and organizing before and after the transport) was 280.00 (268.75 to 293.00), 315.50 (304.75 to 330.75), and 338.00 (319.50 to 360.25) seconds for four, five, and six fluid tubings, respectively, using the conventional method and 274.50 (261.75 to 289.25), 288.00 (271.75 to 298.25), and 301.00 (284.50 to 310.75) seconds, respectively, using the new method (P=0.024, P<0.001, and P<0.001, respectively). CONCLUSION: The ETAD was convenient to use, reduced the time to arrange medical tubings, and is expected to assist medical staff during intra-hospital transport.
RESUMO
INTRODUCTION: While therapeutic hypothermia (TH) is in clinical use, its efficacy in certain patient groups is unclear. This study was designed to describe the characteristics and outcomes of patients with out-of-hospital cardiac-arrest (OHCA) caused by asphyxia, who were treated with TH. PATIENTS AND METHODS: A multicentre, retrospective, registry-based study was performed using data from the period 2007-2012. Comatose patients who were treated with TH after asphyxial cardiac arrest were included, while those who with cardiac arrest attributed to hanging, drowning or gas intoxication were excluded. RESULTS: Of a total of 932 OHCA patients in the registry, 111 were enrolled in this study. The mean age was 65.8±16.3 years with individuals who were ≥65 years of age accounted for 61.3% of the cohort. Foreign-body airway obstruction was the most common cause (70.3%) of the cardiac arrest. Eighty patients (72.1%) presented with an initial non-shockable rhythm. In all institutions target TH temperatures were 32-34°C, but TH maintenance times varied. A total of 52 patients (46.8%) survived, of whom six patients (5.4%) showed a good neurologic outcome (cerebral performance category scale 1-2). The pupil light reflex, corneal reflex and time to return of spontaneous circulation (p=0.012, 0.015 and 0.032, respectively) were associated with survival. Witnessed arrest, age, previous lung disease, bystander basic life support and time factors were not associated with survival. CONCLUSION: About half of patients who underwent TH after asphyxial cardiac arrest survived, but a very small number showed a good neurologic outcome. The TH maintenance times were not uniform in these patients. Additional research regarding both the appropriate TH guidelines for patients with asphyxial cardiac arrest and improvement of their neurologic outcome is needed.
