Usefulness of ultrasonography for the evaluation of catheter misplacement and complications after central venous catheterization

OBJECTIVE: To assess whether ultrasonographic examination compared to chest radiography (CXR) is effective for evaluating complications after central venous catheterization. METHODS: We performed a prospective observational study. Immediately after central venous catheter insertion, we asked the radiologic department to perform a portable CXR scan. A junior and senior medical resident each performed ultrasonographic evaluation of the position of the catheter tip and complications such as pneumothorax and pleural effusion (hemothorax). We estimated the time required for ultrasound (US) and CXR. RESULTS: Compared to CXR, US could equivalently identify the catheter tip in the internal jugular or subclavian veins (P=1.000). Compared with CXR, US examinations conducted by junior residents could equivalently evaluate pneumothorax (P=1.000), while US examinations conducted by senior residents could also equivalently evaluate pneumothorax (P=0.557) and pleural effusion (P=0.337). The required time for US was shorter than that for CXR (P < 0.001). CONCLUSION: Compared to CXR, US could equivalently and more quickly identify complications such as pneumothorax or pleural effusion.

Factors affecting the urologist’s decision to administer ureteral stone therapy: a retrospective cohort study

OBJECTIVE: We aimed to evaluate the factors influencing treatment option selection among urologists for patients with ureteral stones, according to the stone diameter and location. METHODS: We retrospectively reviewed the records of 360 consecutive patients who, between January 2009 and June 2014, presented to the emergency department with renal colic and were eventually diagnosed with urinary stones via computed tomography. The maximal horizontal and longitudinal diameter and location of the stones were investigated. We compared parameters between patients who received urological intervention (group 1) and those who received medical treatment (group 2). RESULTS: Among the 360 patients, 179 (49.7%) had stones in the upper ureter and 181 (50.3%) had stones in the lower ureter. Urologic intervention was frequently performed in cases of upper ureteral stones (P<0.001). In groups 1 and 2, the stone horizontal diameters were 5.5 mm (4.8 to 6.8 mm) and 4.0 mm (3.0 to 4.6 mm), stone longitudinal diameters were 7.5 mm (6.0 to 9.5 mm) and 4.4 mm (3.0 to 5.5 mm), and ureter diameters were 6.4 mm (5.0 to 8.0 mm) and 4.7 mm (4.0 to 5.3 mm), respectively (P<0.001). The cut-off values for the horizontal and longitudinal stone diameters in the upper ureter were 4.45 and 6.25 mm, respectively (sensitivity 81.3%, specificity 91.4%); those of the lower ureter were 4.75 and 5.25 mm, respectively (sensitivity 79.4%, specificity 79.4%). CONCLUSION: The probability of a urologic intervention was higher for patients with upper ureteral stones and those with stone diameters exceeding 5 mm horizontally and 6 mm longitudinally.

Comparison between an instructor-led course and training using a voice advisory manikin in initial cardiopulmonary resuscitation skill acquisition

OBJECTIVE: We compared training using a voice advisory manikin (VAM) with an instructor-led (IL) course in terms of acquisition of initial cardiopulmonary resuscitation (CPR) skills, as defined by the 2010 resuscitation guidelines. METHODS: This study was a randomized, controlled, blinded, parallel-group trial. We recruited 82 first-year emergency medical technician students and distributed them randomly into two groups: the IL group (n=41) and the VAM group (n=37). In the IL-group, participants were trained in “single-rescuer, adult CPR” according to the American Heart Association's Basic Life Support course for healthcare providers. In the VAM group, all subjects received a 20-minute lesson about CPR. After the lesson, each student trained individually with the VAM for 1 hour, receiving real-time feedback. After the training, all subjects were evaluated as they performed basic CPR (30 compressions, 2 ventilations) for 4 minutes. RESULTS: The proportion of participants with a mean compression depth ≥50 mm was 34.1% in the IL group and 27.0% in the VAM group, and the proportion with a mean compression depth ≥40 mm had increased significantly in both groups compared with ≥50 mm (IL group, 82.9%; VAM group, 86.5%). However, no significant differences were detected between the groups in this regard. The proportion of ventilations of the appropriate volume was relatively low in both groups (IL group, 26.4%; VAM group, 12.5%; P=0.396). CONCLUSION: Both methods, the IL training using a practice-while-watching video and the VAM training, facilitated initial CPR skill acquisition, especially in terms of correct chest compression.

The Analysis about Tendency of Emergency Medicine in Pain Control

PURPOSE: Inadequate treatment of pain, which has been termed as “oligoanalgesia”, appears to be common phenomenon the emergency department (ED). In order to improve pain recognition and management, a study concerning physician characteristics on pain and pain management is needed. METHODS: This study was based on a survey that targeted emergency medicine doctors from September to November 2015 (the response rate was 7%). Firstly, the survey showed that physicians preferred medicating on five diseases abdominal pain, cancer, simple musculoskeletal disease, trauma, headache in the ED. Secondly, it demonstrated the criteria used to choose the analgesic treatment in accordance with each disease and the level of pain, which is determined using a numerical rating scale (NRS). RESULTS: In the cases of abdominal pain that requires surgery, cancer pain, and multiple trauma, physicians preferred using an opioid as the first medication, while non steroidal anti inflammatory drugs (NSAIDs) are prescribed in most of the other cases. Meperidine was the preferred choice as the opioid. For almost diseases, the NSAIDs are selected in the lower NRS cases over the opioid. Physicians deal with pain of patients who are already diagnosed with specific diseases, such as cancer, while they avoid managing pain from those patients who have not been definitively diagnosed with a specific disease. CONCLUSION: Physicians in the ED prefer the use of NSAIDs as the analgesic treatment, in particular, prescribing meperidine as the preferred opioid. However, it seems that they are hesitant to manage pain without a clear diagnosis.

Comparison between an Instructor-led Course and Training Using a Voice Advisory Manikin in Initial Cardiopulmonary Resuscitation Skill Acquisition

PURPOSE: Purpose: We compared the outcomes of training between the use of voice-advisory manikin (VAM) and instructor-led (IL) courses with respect to the acquisition of initial cardio-pulmonary resuscitation (CPR) skills, as defined by the 2010 resuscitation guidelines.

Correlation between Tissue Oxygen Saturation and Global Oxygenation Parameters in Emergency Patients: A Pilot Clinical Study

PURPOSE: Near-infrared spectroscopy (NIRS) can noninvasively assess changes in tissue oxygen saturation (StO₂). The primary concern of the current study is to determine whether StO₂ can be used as a surrogate for global oxygenation parameters such as central venous oxygen saturation (ScvO₂), lactic acid, and base deficit (BD) in patients presenting to the emergency department (ED). METHODS: This was a prospective, observational study in patients requiring central venous catheter placement, admitted to the ED with complaints classified as infectious and non-infectious etiology. The NIRS sensor (15 mm probe) was applied on the thenar eminence for at least 3 minutes and ScvO₂, arterial lactic acid, and BD were measured during insertion of a central venous catheter. Data were analyzed using a simple correlation and Bland-Altman plot. RESULTS: A total of 120 patients were enrolled in the study and further classified as an infection (n=39) and a noninfection (n=81) group. Lactic acid BD showed significant correlation with StO₂ in total and in non-infection patients but the degree of correlation was weak and these correlations were not observed in infection patients. Approximately 94% of the difference between StO₂ and ScvO₂ was placed within limit of agreement but there was a risk that StO₂ may overestimate ScvO₂ when ScvO₂ becomes lower. When patients were assigned to two groups according to laboratory results (lactic acid 4.0 mmol/L; BD > 3.0 mmol/L; ScvO₂> 65% or 75%), no significant difference in StO₂ was observed between the two groups. CONCLUSION: In ED patients suspected of having systemic hypoperfusion, StO₂ showed a weak correlation with lactic acid and BD in non-infection patients and no correlation in infection patients. In addition, as ScvO₂ decreased, the difference between StO₂ and ScvO₂ showed a tendency to increase, and StO₂ was much higher than ScvO₂ at low ScvO₂ level. Therefore, before using StO₂ as surrogate for ScvO₂, lactic acid and BD in critically ill patients presenting to the ED, further investigation should be conducted to overcome the limitations of NIRS addressed in this study.

Three-Dimensional Scapular Kinematics in Patients with Reverse Total Shoulder Arthroplasty during Arm Motion

BACKGROUND: There have been few reports on altered kinematics of the shoulder after reverse total shoulder arthroplasty (RTSA). We investigated differences in 3-dimensional (3D) scapular motions assessed using an optical tracking system between RTSA treated shoulders and asymptomatic contralateral shoulders during arm motion. METHODS: Thirteen patients who underwent RTSA were assessed for active arm elevation in 2 distinct elevation planes (sagittal plane flexion and scapular plane abduction). Their mean age was 72 years (range, 69 to 79 years) and the mean follow-up was 24.4 months (range, 13 to 48 months). The dominant side was the right side in all the 13 patients, and it was also the side treated with RTSA. Scapular kinematics was recorded with an optical tracking system. The scapular kinematics and the scapulohumeral rhythm (SHR) of the RTSA shoulders and asymptomatic contralateral shoulders were recorded and analyzed during arm elevation. RESULTS: There were no significant differences in internal/external rotation and anterior/posterior tilting of the scapula between shoulders during arm motion (p > 0.05). However, upward rotation of the scapula differed significantly during arm motion (p = 0.035 for sagittal plane flexion; p = 0.046 for scapular plane abduction). There were significant differences in the SHR between the two shoulders (p = 0.016 for sagittal plane flexion; p = 0.021 for scapular plane abduction). CONCLUSIONS: The shoulder kinematics after RTSA showed significant differences from the contralateral asymptomatic shoulders. Increased upward rotation and decreased SHR after RTSA indicate that RTSA shoulders use more scapulothoracic motion and less glenohumeral motion to elevate the arm.

Effective Postoperative Use of Dexmedetomidine in a Child with Severe Pulmonary Arterial Hypertension Secondary to Congenital Ventricular Septal Defect / 대한구급학회지

Although alpha2-adrenoceptor agonists are widely used as postoperative sedatives in adults, the postoperative effects in pediatric patients with secondary pulmonary arterial hypertension (PAH) due to congenital heart disease are not well known. We experienced a case of successful ventilator weaning with continuous intravenous administration of dexmedetomidine (DEX) after surgical correction in a 46-month-old child with congenital ventricular septal defect (VSD) with severe PAH. She underwent VSD closure on cardiopulmonary bypass (CPB). After successful weaning from the CPB, hemodynamics and oxygenation were stabilized on DEX and nitroglycerin in the intensive care unit. The patient was successfully weaned from the ventilator 46 hours after surgery. The transthoracic echocardiogram two weeks after surgery showed a closed VSD with no residual shunt and trivial tricuspid regurgitation (Vmax = 2.5 m/sec) without PAH.

The Usefulness of Cardiac Biomarker in Patients with Acute Ischemic Stroke

BACKGROUND: Cardiac enzymes such as creatine kinase-MB, troponin I, and brain natriuretic peptide (BNP) are thought to be useful prognostic factors in patients with acute ischemic stroke. This study investigated the efficacy of cardiac biomarkers as prognostic factors. METHODS: We reviewed patients with acute ischemic stroke whose cardiac biomarkers had been measured and who were admitted to our hospital between January 2012 and December 2013. The cardiac biomarkers were measured within 24 hours after admission to the emergency room. We evaluated the clinical characteristics and compared the outcomes of the patients based on their cardiac biomarkers. RESULTS: The following cardiac biomarkers were measured in 219 patients with acute ischemic stroke: creatine kinase-MB (n=218), troponin I (n=219), and BNP (n=143). Statistically significant differences were observed in older age (68.77+/-12.42 vs. 74.59+/-6.68, p<0.05), insula involvement (30.5% vs. 59.1%, p<0.01), and higher BNP (259.75+/-422.65 vs. 667.06+/-1093.22, p<0.01). CONCLUSIONS: These results suggest that measuring all cardiac biomarkers may be not effective in determining the prognosis of acute ischemic stroke. However, BNP may be a superior to troponin I in predicting the prognosis.

Causing Factors to Determine Whether to Administer Analgesics for Patients with Isolated Long Bone Fracture in Emergency Department

PURPOSE: Many patients complain of pain due to fracture in the emergency department (ED). However, pain management in these patients has not been performed well. The objective of this study is to describe analgesic utilization and assess factors associated with analgesic use in patients with isolated long-bone fractures during the ED visit. METHODS: We retrospectively reviewed electronic medical records of patients presenting to two EDs with an isolated long bone fracture from January to December 2012. A total of 358 patients were enrolled, and sex, age, arrival route, mechanism of injury, fracture type, fracture location, drug used for pain control, arrival time, physician in charge primary care, and disposition were analyzed. RESULTS: Analgesics were administered to 50% of patients between 20~60 years, whereas 11.3% of patients under 20 years old and 38.7% above 60 years old (p<0.01) received analgesics. Better pain control was achieved in females, young adults, patients cared for by emergency medicine residents, and visits made by emergency medical service or at dawn. CONCLUSION: The pain control rate of children is lower than that of adults in patients with an isolated long bone fracture. Active strategies for pain management are necessary by triage physicians from this time forward.

A Case of Lemierre Syndrome

Lemierre syndrome is a rare syndrome caused by an acute pharyngitis with secondary septic thrombophlebitis of the internal jugular vein and metastatic infections. Although mortality from Lemierre syndrome is low, it remains a potentially life-threatening disease that requires careful consideration, as its early diagnosis and treatment is essential to prevent metastatic infection. We report a case of a 19-year-old woman who presented with a sore throat and right upper quadrant pain. Abdominal and pelvic computerized tomography (CT) showed acalculous cholecystitis with hepatosplenomegaly. The chest CT showed septic emboli in both lung fields and the neck CT revealed thrombosis in the left internal jugular vein. The patient was treated with antibiotics. After nine days, the chest CT showed a further increase in the size of the septic embolism and the patient was treated with anticoagulants. After 23 days, the size of septic emboli in the lung significantly decreased and the patient was discharged.

Efficacy and Necessity of the Certification Program for Emergency Medical System Directors on the Actual On-Line Medical Direction

PURPOSE: The purpose of this study is to evaluate the usefulness and necessity of an emergency medical service director program for board certified emergency physicians. METHODS: A retrospective analysis of records of direct medical advice provided by board certified emergency physicians in the Busan area from April 1, 2011 to July 11, 2011 was conducted. The medical and legal validity of the medical direction was evaluated by two independent emergency physicians with experience and certification in the field of medical control. RESULTS: Fifteen emergency physicians provided direct medical control during the study period. Five of them were certified as an emergency medical service (EMS) director by the Korean council of EMS physicians (KCEMSP), and the other 10 were not. An analysis of 992 cases of direct medical direction was performed. No differences in the diagnostic appropriateness and medical validity of medical advice were observed between the two groups. A significant difference was observed in legal validity (p=0.048). However, in multivariate analysis, experience as a certified emergency physician was a significant factor determining legal validity (p=0.02), while certification by the KCEMSP was not significant. CONCLUSION: The current EMS director certification program did not have a significant influence on the appropriateness of direct medical direction. EMS director courses and emergency medicine residency programs are in need of improvement in the legal aspect of prehospital emergency service.

Analysis of the Clinical Features and Prognostic Factors in Sea Water Drowning Patients

PURPOSE: Drowning is a common preventable cause of accidental death. Although many studies about drowning injuries have been conducted, most are related to freshwater drowning. The aim of this study was to analyze the clinical features and prognostic factors in seawater drowning patients. METHODS: This study was performed retrospectively with sea water drowning patients who visited the emergency department at Pusan National University Hospital between January 2005 and December 2009. RESULTS: In total, 51 sea water drowning patients presented at the emergency department with a mean age of 48.65+/-15.40 years. The survival group included 42(82.4%) patients, and the death group was comprised of nine patients(17.6%). Fifteen patients arrested in the field, and cardiopulmonary resuscitation (CPR) was performed. Median immersion time in the death group was 15.0 minutes (range, 9.5~22.5 minutes). Among the death group, five patients had respiratory acidosis and nine showed pulmonary edema on a chest X-ray. Initial sodium level in the survival group was 146.30 mEq/L (range, 142.38~152.60 mEq/L), but the level was normalized with isotonic saline. CONCLUSION: Most drowning injuries occurred at night and in relatively young aged patients. CPR in the field did not result in good outcomes because of the longer immersion time. The death group had respiratory acidosis. Because the survival group did not show significant hypernatremia, isotonic saline as an initial fluid was thought to be appropriate. Drowning injuries occur differently based on geographic and social characteristics; therefore, local characteristics should be considered to establish preventive measures.

Correlation Between Pulmonary Contusion and Myocardial Contusion in Patients with Multiple Injuries

PURPOSE: This study was conducted to evaluate the correlations among pulmonary contusion severity, trauma score and cardiac troponin I (cTnI) level. METHODS: We prospectively evaluated patients with multiple injuries who had been admitted to the emergency department (ED) from July 2007 to July 2008. We first measured the total creatinine kinase (CK), the MB fraction of CK (CK-MB), TnI, and myoglobin within 2 hours after the injury. We then checked the electrocardiogram, x-ray, and computed tomography (CT) results. Finally, we assessed the injuries as variables and then compared the results for patients with elevated TnI levels (group A) and patients whose TnI levels fell within the normal range (group B). RESULTS: Eighty-six of the 92 patients admitted to the ED were enrolled. The pulmonary contusion score (PCS) was well correlated with PaO2/FiO2. TnI levels were correlated with PCS. When TnI levels were above 0.86 ng/ml, the mortality was estimated with 100% sensitivity and 86.1% specificity. CONCLUSION: Pulmonary contusion severity is correlated with TnI level. When the PCS is high and the cTnI level is elevated in multiple-injury patients, we recommend continuous cardiac monitoring and further evaluation.

Does the General Public Comply with Hospital Guidance Conveyed at the Emergency Medical Information Center?

PURPOSE: This study investigated the compliance of the general public to the guidance conveyed by hospital emergency medical information centers. METHODS: This study included the incidences of inquiry on hospitals and clinics to Busan Emergency Medical Information Center by the general public for a 2-week period from January 4-17, 2009. Information obtained included general characteristics, time of hospital arrival and departure, length of hospitalization, hospitals visited, and treatment outcome. RESULTS: A total of 939 incidences of hospital guidance to the general public were examined. The degree of compliance was 71.2%, the ratio of the primary and secondary facility that the participants visited were 88.6% and 93.5% of the participants in this study were discharged from hospitals after their visit. Patients who complied with the information received displayed a shorter period of hospitalization than non-compliant patients. CONCLUSION: Emergency medical information centers may help ease the unnecessary use of emergency rooms by providing information on diseases to the general public and effectively distributing medical resources with guidance to proper hospitals according to the degree of symptoms.

Successful Hemostasis by the use of Recombinant Factor VIIa in Uncontrolled Active Hemorrhage of Multiple Trauma Patients

PURPOSE: Uncontrolled bleeding is a leading cause of death in multiple-injury patients. It is very difficult to control hemorrhage due to microvascular injury in soft tissue by surgery or vascular intervention. Thus, hemostatic agents such as recombinant activated coagulation factor VII (rFVIIa) have become popular with regard to reducing transfusion volumes and correcting the hemorrhage-associated coagulopathy. METHODS: From March 2007 to January 2010 we used rFVIIa in 15 multiple-injury patients. Transfused packed red blood cell (pRBC) volume was compared before and 6 h after administration of rFVIIa. Complete blood count, prothrombin time and activated partial thromboplastin time were also checked. RESULTS: Mortality rate correlated strongly with initial severity of coagulopathy. Transfused pRBC volumes per hour were reduced significantly after rFVIIa (p=0.01), and coagulopathy was also significantly corrected. Thromboembolic events such as acute myocardial infarction and cerebrovascular attack, a fatal complication of rFVIIa, did not occur. CONCLUSION: The administration of rFVIIa can correct hemorrhage associated coagulopathy and reduce pRBCs transfusion volume. A quick decision regarding the administration of rFVIIa is needed for a more favorable outcome in multiple-injury patients with hemorrhagic shock.
