A 14-year-old boy with multiple trauma and bilateral basal ganglia hemorrhage due to coronavirus disease 2019: a case report.

BACKGROUND: In December 2019, coronavirus disease 2019 spread worldwide, causing acute respiratory distress syndrome. Coronavirus disease 2019 presents from an asymptomatic infection to severe disease causing multiorgan failure. Neurological manifestations were observed in some patients, including intracerebral hemorrhage. Bilateral basal ganglia hemorrhage is rare due to trauma. CASE PRESENTATION: Our patient was a 14-year-old Iranian boy with multiple trauma and loss of consciousness who tested positive for coronavirus disease 2019. The brain computed tomography scan reported bilateral basal ganglia hemorrhage. Bilateral ground glass opacity was reported through a chest computed tomography scan. DISCUSSION AND CONCLUSIONS: In this study, we reported a 14-year-old boy referred to the emergency room due to multiple trauma. Through the medical interventions, bilateral basal ganglia hemorrhage was discovered incidentally. Coronavirus disease 2019 was detected in this patient on the basis of findings in chest computed tomography scan and positive real reverse transcription polymerase chain reaction test. Several clinical reports and series exploring the relationship between coronavirus disease 2019 and ischemic strokes have been published. Coronavirus disease 2019, like other acute respiratory syndromes, can invade the central nervous system through hematogenous and neuronal dissemination or it can be an immune response to the cytokine storm. In conclusion, it is vital to know the pathophysiology of the neurological manifestations of coronavirus disease 2019 and prevent the mild neurological manifestations leading to severe conditions.

Traumatic injuries in children during COVID-19 pandemic: a national report from northern Iran.

BACKGROUND: There are no comprehensive and accurate statistics on epidemiology and clinical features, especially during the COVID-19 period. The present study tries to describe the pediatric traumas in a referral treatment center in northern Iran during the COVID-19 period and to compare the available statistics with the years before pandemics to examine the differences in the epidemiology of this event in our country. METHODS: This cross-sectional study was performed on 543 children under 15 years admitted to this hospital due to different types of traumas in the first six months of 2019 (before the COVID-19 pandemic) and the first six months of 2020 (coinciding with the peak of the pandemic). The information was retrospectively collected by reviewing the hospital recorded files and the trauma-specific hospital information system. RESULTS: In total, 436 children were referred before the COVID-19 pandemic period and 107 within the pandemic outbreak. The peak age of patients admitted was 2 to 6 years (32.0%) and 70.5% were male. Most of the pointed children had normal weight. The most common mechanism of trauma before and during the COVID-19 pandemic was falling from a height (46.3% versus 42.1%), followed by road accidents (35.6% versus 36.4%). The overall prevalence of penetrating trauma was 6.9% and 9.3%. The most common body sites affected were the head and neck (32.1%) followed by extremities (before the COVID-19 period) and extremities (29.0%) followed by the head and neck (24.3%) (in the COVID-19 period). The overall rates of multiple trauma before and within the pandemic were also 35.6% versus 35.5%. In children aged 12 to 15 years, road accidents were more reported during the COVID-19 pandemic period (68.4% versus 50.9%) and contrarily falling from a height more before the pandemic (25.5% versus 0.0%). In children under two years of age, head and neck trauma was more reported before the COVID-19 period than in the COVID-19 period (55.6% versus 35.5%), while at this age, limb trauma was more common during the COVID-19 period than before (5.6% versus 20.8%) (P = 0.043). In lean children, abdominal and pelvic trauma were mainly seen in the COVID-19 period (28.6% versus 2.6%) (P = 0.035). CONCLUSION: Referrals of children from traumatic injuries decreased during the COVID-19 period. However, the main differences in the mechanism of trauma and the type and severity of traumatic injuries to children in this period emphasize the provision of specific guidelines for trauma management in children.

Traumatic brain injuries in children during COVID-19 pandemic: a national report from northern Iran.

BACKGROUND: Evidence suggests that referral cases of traumatic injuries have decreased during the COVID-19 pandemic both in childhood and in adulthood. Still we have very little evidence of referrals due to traumatic brain injury among children during the COVID-19 outbreak. The present study aimed to describe epidemiological and clinical features of pediatric traumatic brain injuries. METHODS: This cross-sectional study was performed on all patients under 15 years with any evidence of head trauma, referring to Poursina teaching hospital, a referral center for trauma and road accidents in northern Iran. The patients' data were retrospectively collected by reviewing the hospital recorded files and the trauma-specific hospital information system. RESULTS: Of all 543 pediatric traumatic injuries referred to our hospital during the two pointed periods, 166 had any evidence of head and neck injuries leading to an overall prevalence rate of 30.6%. In this regard, the prevalence rate of head/neck injuries was estimated to be 140 out of 436 within a pre-COVID-19 period (32.1%) and 26 out of 107 within the COVID-19 period (24.3%) indicating no significant difference between the two time periods (P = 0.243). However, assessing the rate of head/neck injuries pre-COVID-19 and COVID-19 periods according to patients' age showed a higher rate of such injuries in pre-COVID-19 as compared to COVID-19 periods in patients aged less than two years (55.6% versus 37.5%, P = 0.013) as well as aged 2 to six years (45.8% versus 30.0%, P = 0.036). CONCLUSION: The rate of admission of children due to traumatic brain injury during the COVID-19 period does not show a significant change compared to before, and only in children under 6 years of age a decrease in referrals due to brain trauma during the COVID-19 period was observed.

Predicting factors for electrocardiographic findings in patients with tramadol-induced seizure.

BACKGROUND: Seizure and electrocardiographic (ECG) abnormalities are of the most common complications of tramadol toxicity. OBJECTIVE: This study aimed to show the prevalence and predictive value of various factors for ECG findings in patients with tramadol-induced seizures. METHOD: In a descriptive cross-sectional study, 146 patients with tramadol-induced seizures referred to Poursina Hospital, Guilan, Iran, between June and November 2018 were enrolled. The clinical manifestations, such as blood pressure, respiratory rate, and pulse rate (PR), and ECG parameters, including PR interval, QRS duration, R wave in aVR lead, and corrected QT interval, were assessed. Appropriate statistical tests were used to analyze the data. RESULTS: We showed that tramadol dose was significantly higher in patients with abnormal ECG findings compared with those with normal ECG pattern both upon admission (p = 0.001) and after 6 hours of admission (p = 0.001). The results found the predictive value of tramadol dose for abnormal ECG patterns upon admission (odds ratio (OR) 1.014, 95 percent CI 1.008 to 1.020) and 6 hours later (OR 1.008, 95 percent CI 1.003 to 1.013) in these patients. In addition, it was revealed that PR was a strong predictor of abnormal ECG findings in patients with tramadol-induced seizures upon admission (OR 1.085, 95 percent CI 1.038 to 1.134). Nevertheless, age only predicted abnormal findings 6 hours later (OR 1.104, 95 percent CI 1.019 to 1.195). CONCLUSION: Tramadol dose, age, PR, and seizures frequency could be used as indicators of abnormal ECG findings in patients with tramadol-induced seizures. KEY POINTS: The results of our study showed a high prevalence of sinus tachycardia, terminal S and R waves in aVR lead terminal S wave, and the combination of these abnormalities in this subset of patients.

Investigation of clinical findings and CT scan in children with minor head trauma.

BACKGROUND: The most common cause of death or severe impairment in children older than one-year-old is traumatic brain injury (TBI). Assessing TBI in children with minor head trauma (MHT) using clinical findings from history-taking and a physical exam is crucial to minimizing unnecessary brain CTs and more accurately predicting TBI. We aimed to evaluate the findings of brain CT scans in children with mild head trauma and their relationship with clinical signs and symptoms to avoid unnecessary interventions in many children with MHT. METHODS: This cross-sectional-analytical study was performed to evaluate the findings of brain CT scans in children with MHT and their relationship with clinical signs and symptoms that were referred to Poursina Hospital in Rasht in the first half of 2021. Children were divided into two age groups: under two years and 2-12 years, and analyzed separately. Initially, a list containing all demographic information, patients' clinical signs, and symptoms were prepared. The collected data were then analyzed using SPSS software version 26. RESULTS: According to the results, the mean age of patients was 66.01 months and 88 were boys (56.4%). The most common mechanism of injury was falling from a height. Most patients had isolated head injuries. Among the accompanying injuries, facial injuries were the most common. Among the clinical factors studied, cranial fracture on CT scan and GCS less than 15 were significantly associated with the occurrence of traumatic brain injury on CT scan. In addition, cranial fracture on CT scan, injury severity, and history of vomiting had the highest positive predictive value, respectively. CONCLUSION: Standard history and clinical examination are sufficient to identify high-risk cases of pediatric head injuries. GCS is the most important risk factor for pediatric MHT. Requesting a CT scan is not recommended without these risk factors.

Evaluation the accuracy and cost effectiveness of using the Bernese and Ottawa rules in ankle Sprain.

INTRODUCTION: Ankle sprain is one of the most common musculoskeletal injuries that occur most commonly in the active and working population. Ottawa and Burns Laws are tools for physicians to determine the need for a radiograph of an ankle injury. The purpose of this study was to evaluate the accuracy of the Ottawa and Bernese criteria in patients with torsion of the foot and the economical savings resulting from the application of these two criteria. METHODS: This prospective study was designed to evaluate the two rules burns of Bernese and Ottawa and their economic savings were designed in two phases. They were referred to Poursina Medical Center, Rasht, Iran from September 2019 to the achieved sample size. Data were analyzed by SPSS software version 24 (Statistical Package for Social Science (SPSS) 21, Chicago, IL, USA). RESULTS: A total of 800 patients were included in this study to determine the accuracy of bronze and Ottawa criteria in ankle torsion and the economic cost of using them. Of the 800 patients studied, 430 (53.7%) were male and 370 (46.3%) were female, with a mean age of 35.77±16.42 years. The diagnostic accuracy of the Ottawa criteria is 90% and the diagnostic accuracy of the Bernese criteria is 90.75%. The sensitivity of the Ottawa evaluation method was 97.6% and the specificity was 88%. The sensitivity of Bernese evaluation method was 91% and specificity was 90.7%. CONCLUSION: Because of the higher sensitivity of the Ottawa criterion than the Bernese criteria, it is preferred to determine the probability of fracture for emergency unit personnel. Using these two methods can reduce the time, energy and cost of treatment for the patient during the treatment period.

Evaluation of proximal femoral geometry and its relationship with body mass index in Iranian people: a cross sectional study.

INTRODUCTION: There are several studies on the angle of the femoral neck in different countries. It seems that data of diverse races might help the prediction of femoral neck fractures. The present study aimed to evaluate the femoral neck-shaft angle (FNSA) as a predictive factor of neck fracture in Iranian people. METHODS: In this cross-sectional study, the FNSA was measured using radiographs in 635 patients referred to Poursina Hospital in Rasht from September 2018 to October 2019. The body mass index (BMI) was calculated, age and sex of patients were recorded. Data were analyzed by SPSS. The level of statistical significance was adjusted to P<0.05. RESULTS: According to the measured variables, gender, age, BMI and right FNSA are significant in the way that participants with normal BMI have higher FNSA. FNSA decreased with age and height. Obese people had lower FNSA than normal and overweight people. Comparison of left and right angles using the Wilcoxon test showed a statistically significant difference (P<0.001). The right side FNSA was more than the left (59.94%). Only in 39.9%, the left FNSA was more than the right, and in 0.15% both were the same. CONCLUSION: The present cross-sectional study shows a significant relationship between BMI and FNSA. It is suggested that physician evaluates these parameters for prediction of fracture risk in individuals.

Electrocardiogram Changes as an Independent Predictive Factor of Mortality in Patients with Acute Ischemic Stroke; a Cohort Study.

INTRODUCTION: Various factors such as age and severity of the stroke have been deemed connected with risk of mortality in patients with acute ischemic brain stroke. The present study was performed with the aim of evaluating the role of electrocardiogram (ECG) changes in predicting the outcome of these patients. METHODS: In this cohort study, patients who had presented to the emergency department of a teaching hospital during 1 year and were diagnosed with acute ischemic stroke were evaluated. Demographic data and 12-lead ECG findings of the patients were gathered and their relationship with 1-year mortality was analyzed. RESULTS: Finally, 546 stroke patients with the mean age of 69.5±12.7 (24 - 100) years were studied (53.3% female). 82.7% of the studied patients had at least one of the evaluated ECG abnormalities. The most common ECG findings included normal sinus rhythm (27.3%), inverted T wave (21.2%), sinus tachycardia (11.7%), atrial fibrillation (AF) (11.5%), and pathologic Q wave (9.9%). In the end, 117 (20.9%) patients died during the 1-year follow-up. Frequencies of non-sinus rhythm (p < 0.0001), inverted T wave (p = 0.0001), AF rhythm (p<0.0001), pathologic Q (p<0.0001), ST segment changes (p = 0.011), and atrioventricular (AV) node block (p = 0.007) were significantly higher in patients who died. ECG changes increased the odds of 1-year mortality of these patients 4 times (Odds ratio = 4.05 with 95% CI: 2.39 - 6.87; p < 0.0001). Additionally, age over 60 years and having a history of cardiac diseases increased the odds of mortality 6 (95% CI: 1.4 - 27.9) and 1.5 (95% CI: 0.9 - 2.1) times, respectively. CONCLUSION: Based on the findings of the present study, it seems that along with age and history of cardiac diseases, ECG changes can be considered as an independent predictive factor of mortality in patients with ischemic stroke.

Cinnarizine/betahistine combination vs. the respective monotherapies in acute peripheral vertigo: a randomized triple-blind placebo-controlled trial.

PURPOSE: To compare the efficacy of cinnarizine/betahistine combination with the respective monotherapies in patients with acute peripheral vertigo (APV). METHOD: A randomized, triple-blind placebo-controlled phase III trial was performed on 162 patients with APV to compare the efficacy of cinnarizine/betahistine combination with the respective monotherapies. Patients were randomly allocated into three groups (n = 54 each) of Bet. (betahistine and placebo), Cin. (cinnarizine and placebo), and Bet. + Cin. (betahistine and cinnarizine). The first group received cinnarizine tablets (25 mg) plus placebo three times a day, the second group received betahistine tablets (8 mg) plus placebo three times a day, and the third group received betahistine (8 mg) plus cinnarizine (25 mg) combination three times a day. The treatments were continued for 1 week. Patients were followed up to 3 days and 1 week after initiation of the treatments for changes in vertigo severity measured by visual grading scale (VAS), mean vertigo score (MVS), and mean concomitant symptom score (MCSS). RESULTS: Results showed a significant difference between the groups in VAS (p = 0.001), MVS (p = 0.0001), and MCSS (p = 0.0001) at 1-week follow-up, where the respective values were significantly lower in the Cin. + Bet. group as compared with the respective monotherapies. Efficacy and tolerability of the treatment were found to be higher in the Cin. + Bet. group at 3-day and 1-week follow-up periods (p = 0.0001, for all comparisons). None of the patients reported any side effects during the study. CONCLUSION: This study indicated the superiority of the cinnarizine/betahistine combination over the respective monotherapies in the treatment of APV. TRIAL REGISTRATION: IRCT20130710013947N9.

Diagnostic Accuracy of Cincinnati Pre-Hospital Stroke Scale.

INTRODUCTION: Stroke is recognized as the third cause of mortality after cardiovascular and cancer diseases, so that lead to death of about 5 million people, annually. There are several scales to early prediction of at risk patients and decreasing the rate of mortality by transferring them to the stroke center. In the present study, the accuracy of Cincinnati pre-hospital stroke scale was assessed. METHODS: This was a retrospective cross-sectional study done to assess accuracy of Cincinnati scale in prediction of stroke probability in patients referred to the emergency department of Poursina Hospital, Rasht, Iran, 2013 with neurologic symptoms. Three criteria of Cincinnati scale including facial droop, dysarthria, and upper extremity weakness as well as the final diagnosis of patients were gathered. Sensitivity, specificity, predictive values, and likelihood ratios of Cincinnati scale were calculated using SPSS version 20. RESULTS: 448 patients were assessed. The agreement rate of Cincinnati scale and final diagnosis was 0.483 ± 0.055 (p<0.0001). The sensitivity of 93.19% (95% Cl: 90.11-95.54), specificity of 51.85% (95% Cl: 40.47-63.10), positive predictive value of 89.76% (95% Cl: 86.27-92.62), negative predictive value of 62.69% (95% Cl: 55.52-72.45), positive likelihood ratio of 1.94% (95% Cl: 1.54-2.43), and negative likelihood ratio of 0.13% (95% Cl: 0.09-0.20) were calculated. CONCLUSION: It seems that pre-hospital Cincinnati scale can be an appropriate screening tool in prediction of stroke in patients with acute neurologic syndromes.

An Epidemiologic Study of Traumatic Brain Injuries in Emergency Department.

INTRODUCTION: Traumatic brain injuries (TBI) are one of the most important causes of death in patients under the age of 25 years and is responsible for one third of total deaths caused by trauma. Therefore, knowing its epidemiologic pattern in different populations seems vital. Therefore, this study aims to examine the epidemiologic pattern of TBI in emergency department. METHODS: In this cross-sectional study, the profiles of 1000 patients affected by TBI were selected using simple random sampling. The examined variables in this study included demographic, season, mechanism of injury, accompanying injuries, level of consciousness, hospitalization duration, computed tomography (CT) scan results, needing surgery, admission to intensive care unit, and outcome of the patient. In the end, independent risk factors for the death of patients were determined. RESULTS: 1000 patients suffering from were studied (81.8% male; mean age 38.5±21.7 years). The frequency of their referral to hospital in spring (31.4%) was more (p<0.01). 45.9% of the patients had a level of consciousness less than 9 based on the Glasgow Coma Scale (GCS). Subdural (45.9%) and epidural bleeding (23.7%) were the most common findings in CT scans in this study (p<0.001). Finally, 233 (23.3%) of the patients were dead. Over 60 years of age, falling and motorcycle accidents, intracranial hemorrhage accompanied by brain contusion, subdural bleeding, a GCS of less than 9, and the need to be admitted to intensive care unit were independent risk factors of death in TBI. CONCLUSION: Age Over 60 years, falling and motorcycle accidents, intracranial hemorrhage accompanied by brain contusion, subdural bleeding, a GCS of less than 9, and need to be admitted to intensive care unit were independent risk factors for the death in TBI patients.

Non-Judicial Hanging in Guilan Province, Iran between 2011 and 2013.

INTRODUCTION: Hanging is one of the most commonly used way to commit suicide in many countries. This method used in suicide is considered a problem in Iran too, but no clear data exists regarding hanging in different regions or the country as a whole. Because of the epidemiologic differences in non-judicial hanging in different regions, this study aimed to assess it in Gilan province, Iran between 2011 and 2013. METHODS: In this cross-sectional study, profiles of hanging cases registered in Poorsina hospital in Gilan, Iran between 2011 and 2013 were evaluated. Age, sex, marital status, place of residency, level of education, occupation, history of suicide, history of clinical illness, season of suicide and hanging outcome were evaluated. RESULTS: 59 cases of hanging (mean age 31.4 ± 13.1 years and 83.0% male) were evaluated. 12 (20.34%) suffered from psychological disorders, and 9 (15.2%) confessed to substance abuse. 7 (11.9%) had a history of suicide attempts by hanging. Hanging was significantly higher in men (p<0.001), people with an education level of less than high school diploma (p=0.02) and the unemployed (p<0.05) patients. In the end, 20 (33.9%) of these attempts resulted in death. CONCLUSION: The results of this study showed that in 2 years, 59 cases committed suicide by hanging themselves, 33.9% of which finally died. Committing suicide by hanging was significantly more prevalent in men, people with an education level of less than high school diploma and the unemployed.

Prevalence of Tramadol Consumption in First Seizure Patients; a One-Year Cross-sectional Study.

INTRODUCTION: Previous studies have shown that there is a probability of seizure even with therapeutic doses of tramadol. Yet, no accurate data exist regarding this problem in Iran. Therefore, the present study aimed to evaluate the prevalence of tramadol consumption in patients with first seizure referred to the emergency department (ED). METHODS: In the present retrospective one-year cross-sectional study, all patients who were referred to the ED of Poursina Hospital, Rasht, Iran, with the complaint of first seizure were evaluated. Demographic data and data regarding history of tramadol consumption, duration, total dose, last dose, and time passed from the last dose of consumption were recorded and analyzed regarding the study questions using SPSS 20. RESULTS: 383 (68.9%) out of the 556 patients referred to the ED, were experiencing their first seizure (mean age 26.43 ± 6.48 years; 70.5% male). 84 (21.9%) patients had recently used tramadol. History of seizure in the family of tramadol consumers was significantly lower (3.6% compared to 11%; p = 0.036). Mean total tramadol consumption dose in the last 24 hours was 140.17 ± 73.53 mg (range: 50-300 mg). Duration of tramadol consumption was less than 10 days in 84.5% (df: 2; χ(2) = 96.1; p < 0.001). In addition, 62 (73.8%) patients had seizure within 6 hours of consumption (df: 3; χ(2) = 29.5; p < 0.001). CONCLUSION: Results of the present study showed that 21.9% of the patients with first seizure had a history of tramadol consumption. Seizure following tramadol consumption is more prevalent in the initial 10 days and within 6 hours of consumption. In addition, it seems that lower doses of tramadol may also induce seizure.

Third Ventricle Colloid Cyst as a Cause of Sudden Drop Attacks of a 13-Year-Old Boy.

Colloid cysts are mucous-filled masses with an outer fibrous layer. These cysts are rare developmental malformation and not a true neoplasm. They usually found incidentally and are asymptomatic; but in some cases may associate with rapid neurologic deterioration, herniation, and sudden death. Recognition of this rare but important diagnosis may result in decreasing mortality. In this report, we presented a 13-year-old boy with complaint of two times drop attack and final diagnosis of colloid cyst in the third brain ventricle.

Report of 121 Cases of Bell's Palsy Referred to the Emergency Department.

INTRODUCTION: According to the high incidence of Bell's palsy (IFP) and lack of clinical data regarding different aspects of disease, the present study investigated 121 Iranian patients with peripheral facial paralysis referred to the emergency department. METHODS: In this retrospective study, all patients with peripheral facial paralysis, referred to the emergency department of Poursina hospital, Rasht, Iran, from August 2012 to August 2013, were enrolled. For all patients with diagnosis of Bell's palsy variables such as age, sex, occupation, clinical symptoms, comorbid disease, grade of paralysis, and the severity of the facial palsy were reviewed and analyzed using STATA version 11.0. RESULTS: 121 patients with peripheral facial paralysis were assessed with a mean age of 47.14±18.45 years (52.9% male). The majority of patients were observed in the summer (37.2%) and autumn (33.1%) and the recurrence rate was 22.3%. The most common grades of nerve damage were IV and V based on House-Brackman grading scale (47.1%). Also, the most frequent signs and symptoms were ear pain (43.8%), taste disturbance (38.8%), hyperacusis (15.7%) and increased tearing (11.6%). There were not significant correlations between the severity of palsy with age (p= 0.08), recurrence rate (p=0.18), season (p=0.9), and comorbid disease including hypertension (p=0.18), diabetes (p=0.29), and hyperlipidemia (p=0.94). The patients with any of following symptoms such as ear pain (p<0.001), taste disturbance (p<0.001), increased tearing (p=0.03), and Hyperacusis (p<0.001) have more severe palsy. CONCLUSION: There was equal gender and occupational distribution, higher incidence in fourth decade of life, higher incidence in summer and autumn, higher grade of nerve damage (grade V and VI), and higher incidence of ear pain and taste disturbance in patients suffered from IFP. In addition, there was significant association between severity of nerve damage and presence of any simultaneous symptoms.

Ketamine and atropine for pediatric sedation: a prospective double-blind randomized controlled trial.

INTRODUCTION: Sedation in children can be a challenge for emergency physicians, which demands for selecting an effective medication with few complications and good analgesic effects. This study has been performed to evaluate the adverse effects of ketamine while using either atropine or placebo in emergency departments. METHODS: This is a prospective randomized controlled trial involving 200 patients with age ranging between 2 and 15 years, who need a painful procedure. Participants randomly were divided into 2 groups both treated by ketamine (1 mg/kg intravenously administered); group 1 received excessive intravenous atropine (0.01 mg/kg), whereas distilled water was given to group 2 as placebo. Adverse effects and duration of the treatments were recorded. RESULTS: From March to September 2010, 200 of 218 eligible patients were enrolled. The mean (SD) age of patients in the intervention group was 7.0 (3.6) years that showed no statistical difference with the control group (age range, 2-15 years; mean, 7.1 [3.8] years). The mean procedure and sedation time between the intervention and placebo groups were not significantly different (P = 0.919 and 0.783, respectively). Several differences between the intervention and placebo groups were noted including nausea and vomiting, but only the difference in hypersalivation was statistically significant (12% vs 28%). Low oxygen saturation was reported only in 2% of the participants, whereas none of the children experienced apnea or laryngospasm during the sedation process. CONCLUSIONS: Atropine added to ketamine significantly reduces hypersalivation without producing any adverse effects on the procedure duration or success rate.
