RESUMEN

BACKGROUND: Corrosive esophageal injury due to accidental ingestion is a serious clinical problem in children particularly in developing countries. The present study was conducted to evaluate the diagnostic utility of technetium-99m-pyrophosphate ((99m)Tc-PYP) scintigraphy in the early stage of esophageal burns by using different concentrations of sodium hydroxide (NaOH) in an experimental rat model. MATERIALS AND METHODS: Twenty-eight male Sprague-Dawley rats, weighing 200-250 g, were used in the study. Esophageal burn model was created in 21 rats by gastrically infusion of various concentrations of NaOH. The rats were divided randomly into three groups: mild-burn group (n = 7) received 15% NaOH, moderate-burn group (n = 7) received 30% NaOH and severe-burn group (n = 7) received 45% NaOH. Seven rats were identified as control group and received normal saline. Three hours after burn injury, 1-mCi (99m)Tc-PYP was administered through tail vein. Two hours after (99m)Tc-PYP administration, static imaging with gamma camera was performed. Then, histopathologic assessment of esophageal samples was achieved properly. RESULTS: All NaOH-applied groups (mild, moderate, and severe) showed a significant higher uptake ratio when compared to control group (P < 0.005). NaOH-applied groups displayed important histologic alterations such as mucosal disintegration, edema, inflammation, and stromal damage when compared to control group. Pearson correlation analysis revealed a significant correlation between the (99m)Tc-PYP uptake ratio and histologic score (P < 0.0005). CONCLUSIONS: The scintigraphic imaging may provide advantages in the early stage of esophageal burns in some patients whom endoscopic procedure is contraindicated because of its high risk of complications such as bleeding and perforation.

RESUMEN

INTRODUCTION: During mass casualty incidents (MCIs), the accuracy and timing of the triage of patients by the emergency department (ED) triage officers are essential. The primary triage is performed at the event's location by paramedics and intends a quick evaluation of the victims. Secondary triage may be used when the transfer of the victim is delayed. In this study, we aimed to investigate the effectiveness of two-point triage in a simulated environment of an MCI in the hospital setting. MATERIALS AND METHODS: In this case-control study, we used an online test module to assess single triage points (Group 1, n = 41) and two triage points (Group 2, n = 40). 60 vignettes for Group 1 and 55 vignettes (5 deceased cases removed) for Group 2 were used. The assessment utilized clinical MCI scenarios in a scheduled online meeting by using the Simple Triage and Rapid Treatment (START) system. Triage time and accuracy of the triage, along with the experience, and previous training of the participants, were assessed. RESULTS: A total of 81 triage officers participated in this study. The participants were divided into two independent groups homogenously according to their profession and experience. Groups were comparable primarily without any statistically significant difference in terms of the profession (p = 0.101), sex (p = 0.923), and MCI experience (p = 0.785). The difference between the two groups was not significant with regard to having received practical or theoretical triage training (p = 0.099). The mean time of a single vignette triage was 19.2 (SD 6.5) seconds and mean percentage of correct triage score was 65.0 (SD 12.6). The participants had a statistically significantly better performance in the single-point triage group regarding the median triage time (p < 0.001) and median percentages of under triage (p = 0.001), but a worse median percentage of over triage (p < 0.001). However, there was no significant difference between the two groups in terms of the percentage of accurate triage. Emergency residents performed better in accuracy and triage time than their non-physician colleagues (p = 0.019). CONCLUSIONS: Two-point triage does not demonstrate better outcomes in terms of accuracy and timing. Triage officers should be trained frequently with the preferred training methodology to prevent improper triage accuracy and timing. Well-defined medical disaster planning should include frequent training of the triage officers with case scenarios.

RESUMEN

BACKGROUND: Current evidence about the low-acuity ED visits of old patients has been generated in various healthcare systems; however, this is not a well-researched area in middle-income countries by patients' perspectives. METHODS: A study of 231 patients attending the ED of a tertiary public hospital was conducted using a structured questionnaire from June to August 2021. Eligible patients were community-dwelling, aged > 65 years, who presented with lower clinical urgency. The questionnaire tool was developed using questions from available studies on health service utilization. Additional commentary was obtained from the patients regarding on the reasons for attending the ED and was administered on weekdays between 8:00 am and 5:30 pm. RESULTS: The study included 221 patients over 65 years of age, with a mean age of 72.21 ± 4.2. A total of 58.4% of the patients thought that they should be examined urgently, 15.4% had symptoms that had lasted more than one month, and 59% requested emergency imaging. Patients preferred the ED via treatment, imaging, transportation opportunities of emergency department, past negative experiences, and access problems with family medicines or appointment problems with specialist outpatient clinics with expectations of continuity of care. CONCLUSION: Old individuals have unique healthcare needs, and the motives behind this group of patients with low-acuity problems to apply to the ED is complex. As one of the key objectives of healthcare policies is to make sure that patients are assessed at proper time and place, studies that consider patient perspectives might lead to accurate conclusions for this aim.

RESUMEN

OBJECTIVE: The emergency department length of stay (EDLOS) is one of the essential parameters of emergency healthcare management efficacy, and prominent factors that contribute to EDLOS are critical in enhancing emergency department (ED) patient care effectiveness, particularly for older patients, which is rarely investigated. METHODS: This single-center, prospective cohort study was performed in the ED of a tertiary care hospital. The patients were classified into two groups according to EDLOS (≥4 h vs. <4 h). The chief complaints, consultant branches, the patients' comorbidities, polypharmacy status, time of presentation, laboratory, imaging investigations, EDLOS, Clinical Frailty Score (CFS) score, mini mental examination test, National Early Warning Score 2 (NEWS2), consultations, and outcome of the patients were compared with Spearman and Kendall tau-b correlations. RESULTS: During the 30-day study period, a total of 222 geriatric patients were included in the study. The mean age of study patients was 79.13±9.43 years, and 47.05% of patients were male. The Median EDLOS was 250 (range, 60-1440) min. The patients who arrived on the night shift (p=0.047), who had chronic heart failure (p=0.025), chronic obstructive pulmonary disease (p=0.03), severe dementia according to the MMSE (p=0.008), higher CFS frailty scores (p=0.03), and higher clinical acuity according to the NEWS2 score, were found to be positively correlated to an EDLOS of >4 h. (p=0.001) Any specialty consultation and specialty consultation number, along with hospitalization, were also positively correlated to an EDLOS of >4 h. (p=0.001). CONCLUSION: High-acuity patients with frailty and dementia are at increased risk for increased EDLOS via consultations. Emergency and consultation physicians should communicate better about which patients are vulnerable to EDLOS case by case, and the patient outcome must be decided as soon as possible.

RESUMEN

BACKGROUND: We evaluated risk factors and frailty assessments to identify fall-prone geriatric patients in the emergency department (ED). METHODS: This prospective study included 264 consecutive patients aged ≥65 years who presented to the ED. The participants were divided into those who had fallen or not. The patient groups were compared in terms of age, sex, presenting complaints (falls vs. others), comorbidities, medications, frailty assessment tools, and orthostatic hypotension (OH). RESULTS: In total, 264 patients were included: 129 (48.8%) patients who had fallen and 135 (51.2%) who hadn't fallen. The mean ages of patients who had fallen and those who had not fallen were 80.48±8.38 and 79.42±7.94 years, respectively. In addition, 62.01% (n=80) and 51.85% (n=70) of patients were females. There were no statistically significant differences between the groups in terms of age or sex (P=0.290 and P=0.096, respectively). In total, 89.92% (n=116) of patients who had fallen had at least one chronic medical condition. There was a significant difference in the proportion of patients with OH between the groups. Frailty scores such as the Edmonton Frail Scale, Frail Non-Disabled Questionnaire, PRISMA-7 questionnaire, Identification of Seniors at Risk test, and Rockwood Clinical Frailty Scale scores were also significantly different between the groups. A higher PRISMA-7 score at admission was found to be an independent predictor of fall risk. CONCLUSION: Falls occur more frequently in the older population and in females. In addition, the frailty assessment scores, except for the FRESH Frailty Scale, were associated with falls in geriatric patients. After elimination of non-significant variables in multivariate analysis, a high PRISMA-7 questionnaire score at admission was identified as an independent predictor of fall risk.

RESUMEN

In this study aimed to examine the effectiveness of ShotBlocker and local vibration on the perceived pain and satisfaction during intramuscular antibiotic injection. The sample of the randomized controlled experimental study consisted of 100 patients (32 in vibration group, 35 in ShotBlocker group, 33 in control group) who applied to the adult emergency clinic for antibiotic (amoxicillin/cefuroxime sodium) injection between April and May 2021. The study data were collected using the Structured Information Form, VAS for Pain and VAS for Satisfaction. CONSORT statement was followed for reporting. After the intramuscular antibiotic injection, a significant difference was found between the groups in terms of the mean scores of VAS for Pain and VAS for Injection Satisfaction (p < .001). It was determined that local vibration application was more effective in reducing the pain and in increasing satisfaction that occurs during intramuscular antibiotic injection according to ShotBlocker and control groups.

RESUMEN

OBJECTIVE: In this study, we examined the level of anxiety and depression, daytime sleepiness, and sleep quality in healthcare workers working during the COVID-19 pandemic. METHODS: This study was conducted in a tertiary care university hospital. Socio-demographic information form, Beck Anxiety Scale, Beck Depression Scale, Pittsburg Sleep Quality Index, and Epworth Sleepiness Scale were used as data collection tools. RESULTS: A total of 273 healthcare workers were recruited into the study. It was determined that there is an enormous mental health burden on healthcare workers. About 100% and 45.4% of the participants got above-threshold scores from Beck Anxiety Scale, and Beck Depression Scale, and the prevalence of daytime sleepiness and impaired sleep quality was 11.4% and 38.8%, respectively. The female gender was found to have more severe anxiety levels and lower sleep quality (p<0.001). In logistic regression analysis, the female gender was a risk factor for having a level of severe anxiety, and the nursing profession was a risk factor for having severe anxiety and low sleep quality (p<0.05). CONCLUSION: Global serious outbreaks cause increased depression and anxiety levels and sleep disorders in healthcare workers. Therefore, we believe that trainings and support which aims to strengthen the psychological well-being of healthcare workers should be implemented.

RESUMEN

A massive explosion have ripped Beirut on August 4, 2020, leaving behind more than 6000 casualties, 800 regular floor admissions, 130 intensive care unit admissions, and over 200 deaths. Buildings were destroyed, hospitals in Beirut were also destroyed, others became nonfunctional. A disaster code was initiated in all the hospitals. Victims were transported by the Lebanese Red Cross or by volunteers to the nearest hospital that was still functional. Hospitals were flooded in patients, the coordination between health care centers was missing. Each hospital was functioning to its maximum capacity. With the many challenges we had, a rapid response was initiated. An effective triage done outside the Emergency had the major role in saving lives. After the Beirut Explosion, an assessment of the disaster plan and a major evaluation of the hospitals' coordination is needed.

RESUMEN

The scientific advancement of the disaster medicine concept started approximately five decades ago. Different disciplines, such as public health, emergency health services, emergency medicine, and military medicine, work within the disaster medicine framework. Disaster medicine aimed to ensure that health services and facilities are operational both in the pre- and post-disaster periods to prevent and reduce the negative health circumstances of the society facing disaster risks. It is a discipline with slow scientific progress due to unclearly systematized multidisciplinary structure and sub-study areas. However, important targets regarding the field of disaster medicine were indicated in the Sendai Framework for Disaster Risk Reduction 2015-2030 published by the United Nations. Among the global goals of disaster medicine, are to reduce the number of deaths and injuries, reduce the number of affected people, strengthen critical facility infrastructure, and ensure functional sustainably of these facilities during disasters. To achieve these goals, disaster medicine is expected to rapidly develop both institutionally and academically. Disaster medicine is a global, mass, administrative, and doctrinal discipline that means beyond clinical studies. Particularly, the development and dissemination of disaster medicine education were emphasized for the first time with the Sendai Framework for Disaster Risk Reduction, which was determined globally in 2015. The disaster medicine discipline is seen to reach a very strong point by 2030.

RESUMEN

BACKGROUND: The current knowledge about novel coronavirus-2019 (COVID-19) indicates that the immune system and inflammatory response play a crucial role in the severity and prognosis of the disease. In this study, we aimed to investigate prognostic value of systemic inflammatory biomarkers including C-reactive protein/albumin ratio (CAR), prognostic nutritional index (PNI), neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), and platelet-to-lymphocyte ratio (PLR) in patients with severe COVID-19. METHODS: This single-center, retrospective study included a total of 223 patients diagnosed with severe COVID-19. Primary outcome measure was mortality during hospitalization. Multivariate logistic regression analyses were performed to identify independent predictors associated with mortality in patients with severe COVID-19. Receiver operating characteristic (ROC) curve was used to determine cut-offs, and area under the curve (AUC) values were used to demonstrate discriminative ability of biomarkers. RESULTS: Compared to survivors of severe COVID-19, non-survivors had higher CAR, NLR, and PLR, and lower LMR and lower PNI (P < .05 for all). The optimal CAR, PNI, NLR, PLR, and LMR cut-off values for detecting prognosis were 3.4, 40.2, 6. 27, 312, and 1.54 respectively. The AUC values of CAR, PNI, NLR, PLR, and LMR for predicting hospital mortality in patients with severe COVID-19 were 0.81, 0.91, 0.85, 0.63, and 0.65, respectively. In ROC analysis, comparative discriminative ability of CAR, PNI, and NLR for hospital mortality were superior to PLR and LMR. Multivariate analysis revealed that CAR (⩾0.34, P = .004), NLR (⩾6.27, P = .012), and PNI (⩽40.2, P = .009) were independent predictors associated with mortality in severe COVID-19 patients. CONCLUSIONS: The CAR, PNI, and NLR are independent predictors of mortality in hospitalized severe COVID-19 patients and are more closely associated with prognosis than PLR or LMR.

RESUMEN

INTRODUCTION: The aim of this randomized controlled experimental study was to evaluate the efficacy of potassium, pH and D-dimer levels in blood, as well as potassium and pH levels in peritoneal lavage fluid, in the early diagnosis of acute mesenteric ischemia. MATERIAL AND METHODS: This study was conducted at the Istanbul University Center of Experimental Medicine after having received approval from the Istanbul University animal testing ethics committee. Male albino Wistar rats (n = 24; 250 to 350 g) were divided into two control groups and two ischemic groups. Levels of potassium, pH, and D-dimer in blood and levels of potassium and pH in peritoneal lavage fluid were analyzed for 1 h and 2 h after the induced acute mesenteric ischemia procedure. The degree of ischemic injury was determined using the histopathological damage score in tissue samples taken from the terminal ileum. RESULTS: Ischemic groups had statistically significant differences in potassium and pH in blood and peritoneal lavage fluid compared to non-ischemic groups (p < 0.05). There was no significant difference between control and ischemic groups in terms of D-dimer and histologic grading results after 1 h (p = 0.132, p = 0.475 respectively), while there was a significant difference between control and ischemic groups after 2 h (p < 0.05). CONCLUSIONS: The levels of potassium, pH, and D-dimer could be useful in daily practice for the early diagnosis of acute mesenteric ischemia.

RESUMEN

OBJECTIVE: In this study we aimed to examine and compare the stress levels and the factors affecting stress levels of physicians working in Emergency Medicine (EM) and Internal Medicine (IM) Departments. METHOD: This is a cross-sectional study performed in a research and training hospital. The study population consisted of 39 physicians. Professional Life Stress Scale (PLSS), Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI) and Acceptance and Action Questionnaire-II (AAQ-II) were used. RESULTS: Thirty-nine physicians (female 56.4%; mean age 32.6±6.8 years) included in analysis. They were from EM (n=19; 48.7%), and IM (n=20; 51.3%). Twenty-six (66.7%) participants had a score of 16-30 points indicating a moderate degree of stress in their professional life. The BAI and BDI scores of the participants ranged from 0 to 36 (mean, 8.4±8.9) and 0 to 29 (mean, 7.6±5.9), respectively, which indicated that the participants were below the psychopathological limits in terms of anxiety and depressive symptoms. AAQ-II scores were found to be significantly lower in emergency physicians (p=0.049) indicating that they had a lower level of experiential avoidance than others. Also, AAQ-II scores were found significantly lower in those who had children (p=0.028). CONCLUSION: Working in EM departments for longer periods is associated with higher stress levels while increases the ability to cope with stress. Our study shows that having children is related with decrease in experiential avoidance, hence higher levels of psychological flexibility. Any significant differences were not found between the groups in terms of PLSS, BAI and BDI scores.

RESUMEN

BACKGROUND: Turkey is an experienced country for both military and civilian mass casualties that arise from explosions and shootings by various terrorist groups. In this study, we aimed to investigate the characteristics of patient flow admitted to our hospital caused by primarily gunshot wounds during the coup attempts on the 15th of July. METHODS: This descriptive, retrospective study included a total of 50 patients who were injured during a coup attempt on the date of July 15, 2016, and admitted to our emergency department (ED). Demographic characteristics, anatomical injury sites, postoperative clinical outcomes, and hospitalization settings were recorded. The Glasgow Coma Scale (GCS), Trauma and Injury Severity Score (TRISS), Abbreviated Injury Scale (AIS), Revised Trauma Score (RTS) and Injury Severity Score (ISS) were used to measure the severity of injuries. RESULTS: A total of 63 medical personnel voluntarily reached the ED within two hours. Extremity injuries were the most common injuries. The mean RTS, GCS, and TRISS scores did not differ significantly between the patients discharged from the ED and the patients who were hospitalized (p>0.05). However, there was a statistically significant difference in the ISS scores (p<0.001, independent t-test). There was no statistically significant difference in the GCS and RTS scores between the discharged and hospitalized patients, although the ISS scores were higher in hospitalized patients (p>0.05 and p<0.001, respectively). A total of 33 patients (66%) were admitted to the hospital for follow-up and/or surgical intervention. Five (10%) of the patients were hospitalized for more than 14 days. CONCLUSION: The management of each disaster is unique. Armed conflicts result in gunshot wounds, and preparations must be focused on surge capacity and a prolonged hospital stay of the patients. In our study, the length of stay in the hospital decreased after the arrival of volunteer staff to the ED, but we should note that the ISS increased. Hospital disaster plans should be reorganized not only for ED but also for the whole hospital.

RESUMEN

BACKGROUND: Coronary artery ectasia (CAE) is a well-recognised disorder characterised by abnormal dilation of the coronary arteries. Underlying mechanisms associated with abnormal luminal dilation in CAE remain to be elucidated. However, histopathological features resemble those of coronary atherosclerosis. Galectin-3 (Gal-3) is a valuable biomarker for both progression and destabilisation of atherosclerotic lesions. To the best of our knowledge, there is no study in the literature examining serum Gal-3 levels in patients with isolated CAE. In the present study, therefore, we aimed to investigate the possible relationship between serum Gal-3 levels and isolated CAE. METHODS: Between March 2016 and March 2017 this prospective, case-controlled study included a total of 49 consecutive isolated CAE patients (31 males, 18 females) diagnosed with CAE by coronary angiography at the catheter laboratory of Medeniyet University, Goztepe Training and Research Hospital, and 43 individuals (19 males, 24 females) with normal coronary arteries. Physical examination, medical history, blood biochemistry and transthoracic echocardiography were performed in both groups. Serum concentrations of Gal-3 were measured using blood samples. RESULTS: Median Gal-3 levels were significantly higher in isolated CAE patients than in the controls [23.2 (23.9 ± 7.1) vs 16.8 ng/ml (17.8 ± 7.3); p < 0.001]. According to the Markis classification, the extent of CAE was not correlated with Gal-3 levels (p = 0.41). Multivariate regression analysis revealed that Gal-3 concentration was an independent predictor of isolated CAE. CONCLUSIONS: Our study results suggest that Gal-3 serum concentrations significantly increased in patients with isolated CAE, indicating that Gal-3 may be involved in the pathogenesis of isolated CAE.

RESUMEN

INTRODUCTION: Mesenteric ischaemia results from a lack of adequate blood flow to and oxygenation of the mesentery and intestines. The aim of the present study was to evaluate the effect of hyperbaric oxygen treatment (HBOT) on the healing process in intestinal mucosa of rats undergoing mesenteric ischaemia and reperfusion. METHODS: Thirty-two Wistar-Albino rats were divided into four groups of eight: 1) ischaemia/reperfusion (I/R); 2) sham operation; 3) I/R+HBOT started 6 hours after reperfusion; 4) I/R+HBOT started 12 hours after reperfusion. In the I/R groups, a vascular clamp was placed across the superior mesenteric artery to occlude arterial circulation for 60 minutes, followed by reperfusion. A dose of HBOT consisted of 100% oxygen breathing for 90 minutes at 2.5 atmospheres absolute pressure. Thirteen doses of HBOT were administered after ischaemia. The rats were sacrificed on the eighth day, and their intestinal tissues were harvested for histopathologic analysis. The tissue levels of catalase, malondialdehyde, and glutathione were determined. RESULTS: The histopathological scores (HSCORE) were consistent with macroscopic examinations. The scores were significantly higher (worse) in Group 1 compared to Group 2, Group 3, and Group 4 (for all comparisons, P < 0.05). Group 4's HSCORE was significantly higher than those of Group 2 and Group 3 (for both comparisons P < 0.05). Group 3's HSCOREs were only marginally higher than Group 2. Group 3 exhibited higher glutathione levels than Group 1 (P < 0.05). There were no significant differences across the groups with respect to malondialdehyde and catalase levels. CONCLUSION: A beneficial effect of HBOT was observed on oxidative stress and inflammation in acute mesenteric ischaemia-reperfusion.

RESUMEN

BACKGROUND: The present objective was to evaluate effects of acetaminophen and mannitol on renal function and histopathology in crush injuries. METHODS: Thirty-six rats weighing 370-400 g each were used. No surgery was performed on the first (control) group. The gastrocnemius muscle regions of each rat in the remaining 5 groups were compressed for 2 or 24 hours. In the 4th group, 100 mg/kg acetaminophen was intraperitoneally administered. In the 5th group, 1 g/kg mannitol was administered. In the 6th group, 100 mg/kg acetaminophen and 1 g/kg mannitol were administered. RESULTS: No statistically significant differences were observed among the treatment groups in terms of sodium, potassium, alanine aminotransferase (ALT), and average creatinine clearance values. Hydropic degeneration, tubular necrosis, presence of immunoperoxidase and myoglobin, tubulus epithelial cell degeneration, and presence of PAS-dyed material in tubular lumen was more prominently decreased in the acetaminophen group than the mannitol group. Improvement was observed in the group that was administered both drugs, compared to the mannitol-only group, though findings were still worse than those of the group administered acetaminophen only. CONCLUSION: In crush injuries, acetaminophen improves histopathological renal damage better than mannitol. When used in conjunction with mannitol, the toxic effect of acetaminophen on the liver is decreased.

The aim of this study was to evaluate whether there is a difference in the return of spontaneous circulation (ROSC) and survival with sequel-free recovery rates between the patients who underwent cardiopulmonary resuscitation (CPR) according to 2005 and 2010 guidelines. This study was conducted in the Bakirköy Dr. Sadi Konuk and Kartal Lütfi Kirdar Training and Research Hospital between dates of October 2010 and 28 February 2011 after approval of Ethics Committee. In the first months of the study, CPR was performed according to AHA 2005 ACLS guidelines (Group-1), while CPR was performed according to AHA 2010 ACLS guidelines after November 2010 (Group-2). Patients were assessed for neurological deficit with Cerebral Performance Categories Scale. Mean age was found as 69.01±13.05 (minimum: 21, maximum: 92) in 86 patients included. Of the 33 patients underwent CPR in the Group 1, ROSC was achieved in 51.5%; and 6.1% of these patients were discharged. Of the 53 patients underwent CPR in the Group 2, ROSC was achieved in 37.7%; and 9.4% of these patients were discharged. Although the number of living patients in Group 2 was higher than Group 1, the difference was not found statistically significant (5 versus 2), (P>0.05). But, neurological outcomes were found better with 2010 compared to 2005 guidelines (3/7 versus 0/2 good cerebral performance). It was found that the 2005 CPR guidelines practices in ED were more successful than the 2010 CPR guidelines practices in ROSC, but less successful in the rate of discharge from hospital and neurological sequel-free discharge rate.

RESUMEN

UNLABELLED: The aim of this study is to investigate the effect of ECG criteria which are used for the distinction between AVNRT and AVRT for the choice of treatment in patients with Supraventricular Tachycardia (SVT). The 77 patients with narrow QRS complex SVT which was treated with Adenosine or Diltiazem in the Emergency Department were evaluated retrospectively. All 12-lead ECG during tachycardia were blindly reviewed according to ECG criteria (Pseudo-r` in V1, Pseudo-S-wave in the inferior leads, Visible P-wave, aVL notch) by a cardiologist and an emergency physician. In this study, while 59.6% of the patients returned to normal sinus rhythm (NSR) after the first dose 6 mg, 64.91% of them after the first dose 12 mg and 71.92% of them after the second dose of 12 mg adenosine, 95% of the patients returned to NSR after the 0.25 mg/kg diltiazem. The most visible ECG findings were visible P waves and the least visible ECG findings were Pseudo-S waves in the inferior leads. It was statistically significant between converted by adenosine to NSR and converted by diltiazem to NSR to the presence of visible P-wave and the aVL lead notch in their ECG findings. CONCLUSION: The rate of return to NSR through diltiazem was found higher than that of adenosine in narrow complex SVT patients. Also, diltiazem may be the first medication to be preferred in the presence of retrograt P wave and aVL notch in the ECG of the patients with narrow QRS complex stable SVT.

RESUMEN

Objective. The aim of this study was to investigate the efficacy of beta-aminopropionitrile (BAPN) and prednisolone on the prevention of esophageal damage and stricture formation after caustic esophageal burn. Method. Twenty-eight rats were divided into four equal groups. In groups 1, 2, and 3, caustic esophageal burns were generated by applying NaOH to the 1.5 cm segment of the abdominal esophagus. Group 4 was for the sham. Normal saline to group 1, BAPN to group 2, and prednisolone to group 3 were administered intraperitoneally as a single daily dose. Results. Treatment with BAPN decreased the stenosis index (SI) and histopathologic damage score (HDS) seen in caustic esophageal burn rats. The SI in group 4 was significantly lower compared with groups 1, 2, and 3. Group 2 had the minimum SI value in corrosive burn groups. The differences related to SI between groups 1, 2, and 3 were not statistically significant. The HDS was significantly lower in group 4 compared with groups 1, 2, and 3. The HDS in group 2 was significantly lower compared with groups 1 and 3. Conclusion. This study demonstrated that BAPN was able to decrease the development of stenosis and tissue damage better than prednisolone.
