Hypertonic Saline in the Treatment of Hemorrhagic Shock
Get PDFContext: The present review discusses different studies about the treatment of hemorrhagic shock (HS) with hypertonic saline (HTS). Evidence acquisition: We have searched the title in the most popular databases containing recent meta-analysis or randomized clinical trials (RCTs). Results: We introduce the hemodynamic effects and mechanisms of action of HTS in HS. Evidence in this field shows controversial results. There are some data supporting the potential benefits of HTS infusion in HS. The goal of research in this field is to identify the best therapy in HS with the least mortality. Conclusion: Our conclusion shows that although HTS can decrease inflammatory response during HS, it can attenuate hypercoagulability and cause complications. There are no data supporting less mortality while treatment with HTS versus other fluids in HS
Analysis of Factors and Medical Errors Involved in Patient Complaints in a European Emergency Department
Get PDFIntroduction: Patients’ complaints from Emergency Departments (ED) are frequent and can be used as a quality assurance indicator. Objective: Factors contributing to patients’ complaints (PCs) in the emergency department were analyzed. Methods: It was a retrospective cohort study, the qualitative variables of patients’ complaints visiting ED of a university hospital were compared with Chi-Square and t test tests. Results: Eighty-five PC were analyzed. The factors contributing to PC were: communication (n=26), length of stay (LOS) (n=24), diagnostic errors (n=21), comfort and privacy issues (n=7), pain management (n=6), inappropriate treatment (n=6), delay of care and billing issues (n=3). PCs were more frequent when patients were managed by residents, during night shifts, weekends, Saturdays, Mondays, January and June. Moreover, the factors contributing to diagnostic errors were due to poor communication, non-adherence to guidelines and lack of systematic proofreading of X-rays. In 98% of cases, disputes were resolved by apology and explanation and three cases resulted in financial compensation. Conclusion: Poor communication, LOS and medical errors are factors contributing to PCs. Improving communication, resolving issues leading to slow health care provision, adequate staffing and supervision of trainees may reduce PCs
A Very General Overview of the Development Pediatric Emergency Medicine as a Specialty in the United States and Advocacy for Pediatric Healthcare; the Charge to Other Countries
Get PDFOne of the first noted instances regarding awareness of pediatric specific illnesses in the United States came from the writings of Dr. Benjamin Rush during the late 1700’s where he titled a section in his medical text “Diseases Specific to Children”. Throughout the 1700’s and 1800’s and even early 1900’s medicine was primarily a generalist profession where all ages were cared for by a personal family physician and there were virtually no subspecialties for adults or children. At that time in American history children were the great neglected segment of society in families, labor, and healthcare and were often treated more as property than valued life. There were a few pediatric advocates of note. Abraham Jacobi is considered the father of modern pediatrics and advocated for pediatrics being separated from the field of obstetrics. His actions were fundamental in the formation of the Section on Diseases of Children within the American Medical Association (AMA). In the 1930s there was a recognized need for separate pediatric specialty care advocacy organization and hence the development of the American Academy of Pediatrics (AAP) occurred. This was primarily born out of the lack of and need for federal funding to support pregnant women and children as well as the need for a foundational organization for the development of pediatrics as a specialty in the United States in the future. In the 1950’s pediatric poisonings became commonplace due to chemicals available after the end of World War II. As a result, the first poison control center was formed in Chicago and a manual was published by the AAP on pediatric poisonings. Similarly, the first cardiac surgeries for congenital heart disease were occurring and the specialty of pediatric cardiology was arising. The rising nuclear threat in the 1950’s and 1960’s also raised concern for disaster planning meeting specific pediatric needs and led to further committees, interest groups and publications. In addition, as trauma specialties and general emergency medicine grew under the auspices of the American College of Emergency Physicians (ACEP) and the American Heart Association (AHA) so did the need for sub-specialization for pediatric emergency medicine (PEM). In the early 1980s as an outgrowth of the ACEP and AAP, plans to cooperate and create the subspecialty of PEM began. The goal of the specialty was to train specialists, procure resources funding for research, and standardize training. The first subspecialty board for PEM was administered in 1992 and has continues to this date. Another outgrowth was federally funded agency called Emergency Medicine Services for Children (EMSC) whose goal was to find and fund resources, research, and training for PEM specialists, particularly prehospital providers. As late as 2001 the Institute of Medicine in their periodic report regarding United States healthcare noted that most emergency departments were still largely deficient regarding preparedness for pediatric emergencies. Since that time there has been intense emphasis on preparedness for pediatric emergencies and now the United States has innumerable academic and community hospitals with full pediatric preparedness. Similarly, with the modern explosion of medical information it is now virtually impossible for any physician to know all of one field. Most certainly no general emergency physician can possibly know everything regarding PEM thus obviating the need for PEM specialists to provide optimum care beyond the basics. Numerous studies in the United States have also demonstrated seriously ill or injured children care receive superior care with better outcomes when cared for in pediatric specific facilities. This does not imply that general emergency medicine and pediatric emergency medicine cannot co-exist and have economy of resources. It simply seems to be true that the best possible pediatric care is delivered by pediatric subspecialists with appropriate resources, funding, facilities and training.
As such it is now inconceivable that an appropriate healthcare system in the United States could exist without easily available pediatric specific resources such as PEM. Nonetheless, pediatrics continues to compete with adult specialties for resources as adults continue to have a conscious and unconscious bias toward them because of perceived greater adult patient productivity and contribution to society as a whole.
In conclusion, no matter what country, there will always be a need for committed individual and organizational advocates for the specific needs of children including the firm belief in pediatric subspecialties such as pediatric emergency medicine
Two Different Endotracheal Tube Securing Techniques: Fixing Bandage vs. Adhesive Tape
Get PDFIntroduction: Emergency physicians should secure Endotracheal tubes (ETT) properly in order to prevent unplanned extubation (UE) and its complications. Despite various available endotracheal tube holders, using bandages or tape are still the most common methods used in this regards. Objective: This study aimed to compare adhesive tape (AT) versus fixing bandage (FB) method in terms of properly securing ETT. Methods: This was an observational longitudinal trial. All patients older than 15-years-old admitted to the ED who had indication for ETT insertion were eligible. Patients were randomly assigned to one of the two groups in which AT or FB was applied. All patients were observed thoroughly in the first 24 hours after intubation. Using a pre-prepared checklist, encountered UE rate and other data were recorded. Results: Seventy-two patients with the mean age of 55.98 ± 18.39 years were finally evaluated of which 38 cases (52.8%) were male. In total, 12% of patients in our study experienced unplanned extubation. Less than 12% of the patients experienced complete UE; there was no statistically significant difference between the two groups (p = 0.24). Comparison of UE with age showed no significant difference (p = 0.89). Male patients experienced more UE, but this was not statistically significant (p = 0.44). Conclusion: It is likely that whether the AT method or FB was applied for securing the ETT in emergency departments, there was no significant difference in rates of unplanned extubation
Do Patients with Chest Pain Benefit from Installing Triage System in Emergency Department?
Get PDFIntroduction: Chest pain, which can be cardiac or non-cardiac and either benign or life-threatening, needs appropriate diagnosis and treatment in emergency department (ED). Objective: The aim of this study was to compare delivery time of primary care for patients with chest pain before and after applying triage system in ED. Methods: Medical records were reviewed of thirty patients (group one) with chief complaint of chest pain who referred to ED between April and July 2008 (before installing triage system) and thirty-five patients (group two) with the same chief complaint who referred between August and September 2009 (after installing triage system). Time between patients’ arrival and beginning of diagnostic and therapeutic interventions including cardiac monitoring, first physician visit time, intravenous line insertion, and electrocardiogram performance were compared between the two groups. Results: Based on the findings, the mean age and sex ratio of studied patients in the two groups were not significantly different (p>0.05). Door to ECG performance, Door to intravenous line insertion, and Door to cardiac monitoring were significantly shorter in post triage installing period than previously (p<0.001). Door to first visit by physician was not statistically different in the two study periods (p=0.421). Conclusion: It is likely that patients with chest pain who referred to ED benefit from installing triage system in terms of performing some nursing care including ECG performance, starting cardiac monitoring, and IV insertion
The Veracity of Troponin Test Requests for Patients Presenting to the Emergency Department with Chest Pain; A Clinical Audit
Get PDFIntroduction: Troponin test is one of the methods for diagnosing acute coronary syndrome, but the overuse and misuse of this test has increased the costs imposed on the health system and the patients. Objective: The present study was conducted to investigate the veracity of troponin test requests for patients presenting to an emergency department with chest pain and examine the effectiveness of training emergency medicine assistants in reducing unnecessary and inappropriate requests in emergency departments. Methods: This clinical audit was conducted in the emergency department of Imam Hossein Hospital, Tehran, Iran, in 2014. Sampling was carried out using the census method and all the cases presenting to the emergency department for whom a troponin test was requested by the emergency medical assistants were included in the research. First, the veracity of the current troponin test requests was assessed; then, training was given to the personnel, and the veracity of the troponin test requests was once again verified after the training was completed. The rate of veracious troponin requests for the patients was measured based on two factors, including the interval between the patients’ admission and the troponin test request, and the interval between the onset of pain and the troponin test request. The veracity of the troponin test request was compared before and after training using the Phi test and Cramer’s V test in IBM SPSS-21. Results: This study examined a total of 500 patients (250 before training and 250 after), who had a mean age of 57.65±18.15 years, including 51.6% men. Significant differences were observed between the mean time of the patients’ admission and the overall and post-training troponin test results (P=0.000), and also between the mean time of the onset of pain and the overall and post-training troponin test results (P=0.000). The number of positive troponin test results did not differ significantly between the patients in either of the two stages (P=0.39). Conclusion: Unnecessary troponin test requests reduced significantly after this clinical audit in the examined emergency department
Pain Relieving Effect of Sublingual Glycerol Trinitrate in Renal Colic: a Randomized Placebo-Controlled Trial
Get PDFIntroduction: Renal colic is caused by colicky spasms of ureters. As has been shown in previous experiments, glycerol trinitrate (TNG) can inhibit these muscular spasms. Objective: This study was performed to assess the pain relieving effect of TNG among patients referred due to renal colic pain to the emergency department (ED). Methods: This study is a randomized, placebo-controlled study on 60 patients with renal colic who were referred to the ED, who were diagnosed clinically to have renal colic, and their pain was more than 5 based on a visual analogue scale (VAS). The patient's pain was recorded at the moment of clinical diagnosis, and each one received one capsule, either 0.4 mg TNG or placebo, plus a 100 mg indomethacin suppository. The pain score was re-assessed after 5 and 30 min. The values were recorded and compared using SPSS-16 software. Results: Sixty patients with a mean age of 35.75 ± 11.99 years were enrolled (73.3% male). Patients in the two groups were matched for age (p = 0.290), sex (p = 0.559), and the presence of microscopic hematuria (p = 0.292). Pain relief from the start point until the end of the intervention was statistical different in all studied patients (p < 0.05); but the comparison between the two groups showed no significant difference in this regard (p = 0.440). Conclusion: It is likely that adding TNG to an indomethacin suppository had no significant effects on better pain management of patients referred with renal colic to the ED
A 26-Year-Old Man with Headache
Get PDFIn this case, changes are made to the shape or amplitude of ECG complexes change alternatively. In the most common form, alternative changes can be viewed better in QRS complexes and in mid precordial leads. These alternative changes can be seen simultaneously in every other QRS complex and T wave. This means that in one beat the amplitude or shape of QRS complexes and T wave are normal and in the next beat the amplitude or shape of QRS complexes and T wave change. Since at times QRS complexes get closer, then they collapse and overlap and after that they gain distance from each other again. The answer to this ECG is a heterotropic transplanted heart.
 
Artificial Intelligence-Based Triage for Patients with Acute Abdominal Pain in emergency Department; a Diagnostic Accuracy Study
Get PDFIntroduction: Artificial intelligence (AI) is the development of computer systems which are capable of doing human intelligence tasks such as decision making and problem solving. AI-based tools have been used for predicting various factors in medicine including risk stratification, diagnosis and choice of treatment. AI can also be of considerable help in emergency departments, especially patients’ triage. Objective: This study was undertaken to evaluate the application of AI in patients presenting with acute abdominal pain to estimate emergency severity index version 4 (ESI-4) score without the estimate of the required resources. Methods: A mixed-model approach was used for predicting the ESI-4 score. Seventy percent of the patient cases were used for training the models and the remaining 30% for testing the accuracy of the models. During the training phase, patients were randomly selected and were given to systems for analysis. The output, which was the level of triage, was compared with the gold standard (emergency medicine physician). During the test phase of the study, another group of randomly selected patients were evaluated by the systems and the results were then compared with the gold standard. Results: Totally, 215 patients who were triaged by the emergency medicine specialist were enrolled in the study. Triage Levels 1 and 5 were omitted due to low number of cases. In triage Level 2, all systems showed fair level of prediction with Neural Network being the highest. In Level 3, all systems again showed fair level of prediction. However, in triage Level 4, decision tree was the only system with fair prediction. Conclusion: The application of AI in triage of patients with acute abdominal pain resulted in a model with acceptable level of accuracy. The model works with optimized number of input variables for quick assessment
