ABSTRACT
OBJECTIVES: There is no sufficient data to provide a clear picture of out-of-hospital cardiac arrest (OHCA) across Türkiye. This study is the first to present the prognostic outcomes of OHCA cases and the factors associated with these outcomes. MATERIALS AND METHODS: The study was conducted in a prospective, observational, multicenter design under the leadership of the Emergency Medicine Association of Turkey Resuscitation Study Group. OHCA cases aged 18 years and over who were admitted to 28 centers from Türkiye were included in the study. Survived event, return of spontaneous circulation (ROSC), survival to hospital discharge, and neurological outcome at discharge were investigated as primary outcomes. RESULTS: One thousand and three patients were included in the final analysis. 61.1% of the patients were male, and the average age was 67.0 ± 15.2. Cardiopulmonary resuscitation (CPR) was performed on 86.5% of the patients in the prehospital period by emergency medical service, and bystander CPR was performed on only 2.9% by nonhealth-care providers. As a result, the survived event rate was found to be 6.9%. The survival rate upon hospital discharge was 4.4%, with 2.7% of patients achieving a good neurological outcome upon discharge. In addition, the overall ROSC and sustained ROSC rates were 45.2% and 33.4%, respectively. In the multiple logistic regression analysis, male gender, initial shockable rhythm, a shorter prehospital duration of CPR, and the lack of CPR requirement in the emergency department were determined to be independent predictors for the survival to hospital discharge. CONCLUSION: Compared to global data, survival to hospital discharge and good neurological outcome rates appear to be lower in our study. We conclude that this result is related to low bystander CPR rates. Although not the focus of this study, inadequate postresuscitative care and intensive care support should also be discussed in this regard. It is obvious that this issue should be carefully addressed through political moves in the health and social fields.
ABSTRACT
BACKGROUND: Wearable devices, particularly smartwatches like the Apple Watch (AW), can record important cardiac information, such as singlelead electrocardiograms (ECGs). Although they are increasingly used to detect conditions such as atrial fibrillation (AF), research on their effectiveness in detecting a wider range of dysrhythmias and abnormal ECG findings remains limited. The primary objective of this study is to evaluate the accuracy of the AW in detecting various cardiac rhythms by comparing it with standard ECG's lead-I. METHODS: This single-center prospective observational study was conducted in a tertiary care emergency department (ED) between 1.10.2023 and 31.10.2023. The study population consisted of all patients assessed in the critical care areas of the ED, all of whom underwent standard 12lead ECGs for various clinical reasons. Participants in the study were included consecutively. An AW was attached to patients' wrists and an ECG lead-I printout was obtained. Heart rate, rhythm and abnormal findings were evaluated and compared with the lead-I of standard ECG. Two emergency medicine specialists performed the ECG evaluations. Rhythms were categorized as normal sinus rhythm and abnormal rhythms, while ECG findings were categorized as the presence or absence of abnormal findings. AW and 12lead ECG outputs were compared using the McNemar test. Predictive performance analyses were also performed for subgroups. Bland-Altman analysis using absolute mean differences and concordance correlation coefficients was used to assess the level of heart rate agreement between devices. RESULTS: The study was carried out on 721 patients. When analyzing ECG rhythms and abnormal findings in lead-I, the effectiveness of AW in distinguishing between normal and abnormal rhythms was similar to standard ECGs (p = 0.52). However, there was a significant difference between AW and standard ECGs in identifying abnormal findings in lead-I (p < 0.05). Using Bland-Altman analysis for heart rate assessment, the absolute mean difference for heart rate was 0.81 ± 6.12 bpm (r = 0.94). There was strong agreement in 658 out of 700 (94%) heart rate measurements. CONCLUSION: Our study indicates that the AW has the potential to detect cardiac rhythms beyond AF. ECG tracings obtained from the AW may help evaluate cardiac rhythms prior to the patient's arrival in the ED. However, further research with a larger patient cohort is essential, especially for specific diagnoses.

BACKGROUND AND STUDY AIMS: Esophageal burns due to ingestion of corrosive substances are frequently seen in both children and adults. However, there is no standard method of treatment to prevent associated mortality and morbidity. Therefore, this study aimed to evaluate the effects of known antioxidants, namely N-acetyl cysteine and ethyl pyruvate, on esophageal damage due to sodium hydroxide-induced corrosive burns. MATERIALS AND METHODS: Thirty-five female rats were randomly assigned to five equal groups. Group 1 was the sham group, while Group 2 was the control group. Group 3 received N-acetyl cysteine, Group 4 received ethyl pyruvate, and Group 5 received both N-acetyl cysteine and ethyl pyruvate. Rats in the "burn" groups were gavage-fed with 0.2mL of 25% NaOH. All esophagi were extracted on day 4 for histopathological evaluation. RESULTS: Total histopathological damage scores were evaluated at the end of the study. Groups 3 and 5 were significantly different from the control group in terms of total histopathological scores (p = 0.001), while no significant difference was seen with Group 4. Stenosis index results in groups 3 and 5 were similar to those seen with total histopathological scores (p = 0.004). CONCLUSION: N-acetyl cysteine, alone or in combination with ethyl pyruvate, may be useful in the treatment of esophageal damage associated with corrosive substances and in achieving histopathological improvement in an experimental setting.

OBJECTIVES: The aim of this study is to compare the diagnostic values of plasma levels of vascular adhesion protein-1 (VAP-1) and intestinal fatty acid-binding protein (I-FABP) for diagnosing acute mesenteric ischemia (AMI). METHODS: The study used a randomized, controlled experimental design. Forty-two female Sprague-Dawley rats were divided into three control groups and three ischemia groups. Plasma VAP-1 and I-FABP levels were measured, and the extent of ischemic damage was determined using a histopathological damage score in terminal ileum tissue samples. RESULTS: In the early phase of AMI (i.e. at the 30-min time point), VAP-1 levels did not differ between the control and ischemia groups (p > 0.05), but I-FABP levels were significantly higher in the ischaemia groups (p = 0.017). Although both VAP-1 and I-FABP levels increased in the ischaemia groups, only VAP-1 levels showed a significant increase compared to the control group at the 2-h time point (p = 0.011). Ischemic damages associated with AMI became the most prominent at the 6-h time point. During this phase, both VAP-1 and I-FABP levels were significantly higher in the ischemia groups than in the control groups (p = 0.007 and p = 0.002, respectively). Both VAP-1 and I-FABP levels showed a significant correlation with ischemic changes, but a higher correlation was observed for VAP-1 levels (r = 0.771). CONCLUSIONS: Both I-FABP and VAP-1 levels were useful for diagnosing AMI, but VAP-1 levels correlated better with the extent of ischaemic damage.

No association was determined between grayanotoxin levels in blood and clinical data.
ABSTRACT
OBJECTIVE: This study explores the potential use of drones in searching for and locating victims and of motorized transportation of search and rescue providers in a mountain environment using a simulation model. METHODS: This prospective randomized simulation study was performed in order to compare two different search and rescue techniques in searching for an unconscious victim on snow-covered ground. In the control arm, the Classical Line Search Technique (CLT) was used, in which the search is performed on foot and the victim is reached on foot. In the intervention arm, the Drone-snowmobile Technique (DST) was used, the search being performed by drone and the victim reached by snowmobile. The primary outcome of the study was the comparison of the two search and rescue techniques in terms of first human contact time. RESULTS: Twenty search and rescue operations were conducted in this study. Median time to arrival at the mannequin was 57.3min for CLT, compared to 8.9min for DST. The median value of the total searched area was 88,322.0m2 for CLT and 228,613.0m2 for DST. The median area searched per minute was 1489.6m2 for CLT and 32,979.9m2 for DST (p<0.01 for all comparisons). CONCLUSIONS: In conclusion, a wider area can be searched faster by drone using DST compared to the classical technique, and the victim can be located faster and reached earlier with rescuers transported by snowmobile.

OBJECTIVES: To develop a low-cost biomaterial-covered chest tube simulation model and assess its possible usefulness for developing the chest tube insertion skills among medical interns. Methods: This mannequin-based interventional study was performed in a University hospital setting. We included 63 physicians performing emergency medicine internship at the Faculty of Medicine, Karadeniz Technical University, Trabzon, Turkey, between January 2015 and March 2015. A dummy was prepared for training simulation using a display mannequin. Medical interns received instruction concerning pneumothorax and the chest tube procedure. A total of 63 medical interns participating in this interventional study were asked to insert a chest tube in a biomaterial-covered mannequin. A senior trainee scored their performance using a check list and the mean of the total scores was calculated (21 items; total score, 42). Results: The mean procedural score was 40.9 ± 1.3 of a possible 42. The maximum score of 42 was achieved by 39.7% of the medical interns, while another 33.3% achieved a score of 41. Of the participants, 85% succeeded in inserting the tube via an appropriate technique, achieving a score of 40 or more. Conclusion: Our results indicated that this model could be useful for effective training of medical interns for chest tube insertion, which is an important skill in emergency medicine. This biomaterial-covered model is inexpensive and its use can potentially be widened to improve training methods without significant financial demand.

Intracranial subdural hematoma developing following spinal anesthesia is a rare but serious complication. We describe a case of subdural hematoma developing following spinal anesthesia and diagnosed late. A female patient receiving spinal anesthesia for cesarean delivery 45 days prior to arrival at the emergency department presented to our hospital with non-severe headache persisting for 45 days after discharge. Computerized tomography (CT) of the brain performed due to long-term persisting headache resistant to medical treatment and a history of spinal intervention revealed a hypodense chronic subdural hematoma in the left frontoparietal area and a shift from left to right in midline structures. The patient was operated and discharged without sequelae on the 7th day postoperatively. Care must be taken over subdural hematoma in the presence of headache after spinal anesthesia persisting despite fluid intake and medical treatment and exceeding 48 h in duration, and diagnosis must not be delayed.
ABSTRACT
OBJECTIVE: Migraine and subarachnoid hemorrhage (SAH) patients present to emergency departments with the similar symptoms as headache, nausea, and vomiting. This study investigated whether the neutrophil-lymphocyte ratio (NLR) could distinguish patients with SAH from those with migraine. METHODS: This retrospective study was performed after research ethics committee approval. Data were gathered from the ED and neurology clinics of a university hospital between January 2015 and January 2016, from patients with symptoms of headache (primarily), nausea and vomiting. One hundred and twenty one with SAH, 123 patients with migraine and 987 with other primary headache syndromes were considered. Neutrophil-lymphocyte ratios (NLR-1) were compared between groups on admission. In SAH patients NLR taken on the 24th-30th hour of admission (NLR-2) was compared to admission NLR. RESULTS: NLR values, showed that the median NLR values of SAH patients were significantly higher than migraine and other headaches group values (p<0.001; p<0.001). There was no statistically significant difference between the NLR values of the migraine and control groups (p>0.05). An NLR cut-off value of 4.02 produced 85.95% sensitivity, 97.46% specificity, a 33.79 positive likelihood ratio (LR+), and a 0.14 negative likelihood ratio (LR-). A statistically significant increase was observed in median NLR-2 values compared to median NLR-1 values in SAH patients (p<0.001). CONCLUSION: In this retrospective analysis, NLR distinguished patients with SAH from those with migraine. Presence of SAH should be evaluated from discharged and readmitted patients (with headache symptoms) when an increase in NLR between initial and readmission levels is observed.

STUDY OBJECTIVE: To assess the effectiveness of nebulized fentanyl used for analgesia in renal colic. MATERIALS/METHODS: This research was planned as a randomized, blinded study in which prospectively collected data were analyzed retrospectively to compare nebulized and intravenous (iv) fentanyl therapies. Patients with renal colic with 'moderate' or worse pain on a four-point verbal pain score (VPS) or with pain of 20mm or above on a 100-mm visual analogue score (VAS) at time of presentation were randomized into iv fentanyl (n=62) or nebulized fentanyl (n=53) study groups. Decreases in VAS and VPS scores at 15 and 30min compared to baseline, rescue analgesia requirements and side-effects between the groups were compared. RESULTS: Both iv fentanyl and nebulized fentanyl provided effective analgesia in renal colic patients at the end of 30min. However, iv fentanyl provided more rapid and more effective analgesia than nebulized fentanyl. Patients receiving iv fentanyl had lower rescue analgesia requirements than those receiving nebulized fentanyl (37.1% vs 54.7%), although the difference was not statistically significant (p=0.058). In addition, side-effects were more common in the iv fentanyl group compared to the nebulized fentanyl group (22.1% vs 9.4%), although the difference was also not significant (p=0.058). CONCLUSION: Nebulized fentanyl provides effective analgesia in patients with renal colic. However, iv fentanyl exhibits more rapid and more powerful analgesic effects than nebulized fentanyl. Nonetheless, due to its ease of use and few potential risks and side-effects the nebulized form can be used as an alternative in renal colic.

OBJECTIVE: Neuroleptic malignant syndrome (NMS) is a neurological emergency rarely encountered in clinical practice but with a high mortality rate. Cases associated with atypical antipsychotic use or termination of dopamine agonists have been seen in recent years. The purpose of this study was to assess the presence of risk factors for mortality by investigating all clinical and laboratory characteristics of cases with NMS. MATERIAL AND METHODS: This descriptive, cross-sectional study retrospectively investigated all clinical and laboratory characteristics by scanning the ICD-10 codes of patients presenting to the XXXX Faculty of Medicine Emergency Department and diagnosed with NMS between 2006 and 2016. Patients were divided into surviving and non-surviving groups, and the data elicited were subjected to statistical comparisons. RESULTS: The mean age of the 18 patients diagnosed with NMS was 46.9 ± 4.8 years, and 50% were women. In addition to antipsychotics among the drugs leading to NMS, the syndrome also developed as a result of levodopa withdrawal in three patients and metoclopramide use in one patient. Statistically significant differences were determined between the surviving and non-surviving patients in terms of blood pressure, blood urea nitrogen (BUN), creatine kinase (CK) and mean platelet volume (MPV) values (p ≤ 0.05). CONCLUSION: In this study the most common agent that cause NMS was atypical antipsychotics. Also advanced age, increased blood pressure and serum CK, BUN and MPV values were identified as potential risk factors for mortality in NMS.
ABSTRACT
PURPOSE: To investigate the difference in pentraxin 3 (PTX 3) levels between patients with pulmonary contusion and healthy volunteers. MATERIALS AND METHODS: This study was conducted with a group of 20 trauma patients diagnosed with pulmonary contusion and 30 healthy individuals enrolled as a control group in a tertiary university hospital. RESULTS: Median PTX 3 levels were 7.05 (3.29-13.1), ng/ml in the contusion group and 1.03 (0.7-1.58) ng/ml in the control group. PTX 3 titers were significantly higher in patients with pulmonary contusion compared to those of the control group (p<0.001). An area under the curve (AUC) value of 0.968 investigated using ROC analysis to determine the diagnostic value of the PTX-3 in pulmonary contusion patients was measured. A PTX-3 cut-off value of 2.06 produced 95.5% sensitivity and 86.7% specificity. CONCLUSION: PTX 3 levels in pulmonary contusion increased significantly compared to the healthy control group. If supported by wider series, PTX 3 may be expected to be capable of use as a marker in pulmonary contusion.

OBJECTIVE: The objective was to compare the protective effects of N-acetylcysteine (NAC) plus normal saline (NS), sodium bicarbonate (NaHCO3 ) plus NS, and NS alone in the prevention of contrast-induced nephropathy (CIN) after computed tomography pulmonary angiography (CTPA) in emergency patients. METHODS: This study was planned as a randomized, controlled clinical research. Patients undergoing contrast-enhanced CTPA on suspicion of pulmonary embolism (PE) in the emergency department and with at least one risk factor for development of CIN were included in one of three different prophylaxis groups. The groups received 3 mL/kg intravenous (IV) NAC+NS or NaHCO3 +NS solution or NS alone 1 hour before CTPA and 1 mL/kg IV per hour for a minimum of 6 hours after CTPA. CIN was evaluated as the primary outcome and moderate or severe renal insufficiency and in-hospital mortality as secondary outcomes. RESULTS: A total of 257 patients were enrolled in the study. The total level of CIN development was 23.7% (61/257), the level of moderate and severe renal failure was 12.5% (32/257), and the in-hospital mortality rate was 12.8% (33/257). Rates of CIN development in the drug groups were 23.5% in the NAC group (20/85), 21.2% (18/85) in the NaHCO3 group, and 26.4% in the NS group (23/87). Rates of development of moderate or severe renal insufficiency were 9.4% in the NAC group (8/85), 10.6% in the NaHCO3 group (9/85), and 17.2% in the NS group (15/87). In-hospital mortality rates were 12.9% in the NAC group (11/85), 11.8% in the NaHCO3 group (10/85), and 13.8% in the NS group (12/87). No difference was determined between the drug groups in terms of CIN, moderate or severe renal injury, or hospital mortality. CONCLUSIONS: Our results indicate that there is a high risk of CIN in patients with suspected PE despite three different types of prophylaxis being administered, and no statistically significant differences were observed among prophylactic NAC, NaHCO3 , and NS in prevention of CIN following contrast-enhanced CTPA.

INTRODUCTION: The aim of this study was to evaluate patients presenting to the emergency department (ED) with wrist trauma using physical examination findings and functional tests and to identify findings with high sensitivity and specificity among the parameters assessed in patients with fracture in the wrist. The ultimate objective was thus to establish a reliable and widely usable clinical decision rule for determining the necessity of radiography in wrist trauma. METHODS: This prospective, multicenter study was performed in 8 hospitals. The relation between radiologically determined fracture and clinical findings consisting of physical examination findings and functional tests was assessed in terms of whether or not these were markers of radiography requirement, with the aim of identifying predictive values for fracture. RESULTS: A total of 603 eligible trauma patients presented to the participating EDs during the study period. Fracture was identified in 24.5% of patients (n = 148). The 4-way combination with the highest sensitivity was identified as axial compression and the positive distal radioulnar drawer test, and pain with radial deviation and dorsal flexion. Sensitivity at distal ulna palpation was added as a fifth parameter, and sensitivity and negative predictive value thus increased to 100%. CONCLUSION: With their 100% sensitivity and 100% negative predictive values, the Karadeniz wrist rules may represent a clinical decision rule that can be used in practice in EDs. If all 5 findings are negative, there is no indication for wrist radiography.

INTRODUCTION: Reperfusion therapies play an important role in early-period treatment for patients presenting to the emergency department due to stroke. However, the ischemia-reperfusion injury that may occur with reperfusion must then be considered. The purpose of this study was to determine the effectiveness of N-acetylcysteine (NAC) and ethyl pyruvate in preventing ischemia-reperfusion injury. METHOD: This study is a randomized, controlled experimental study. In group 1, rats' left main carotid arteries were clamped. Reperfusion was established by releasing the clamp after 1.5 hours. In group 2, the left main carotid artery was clamped, and 20 mg/kg intraperitoneal NAC was administered after 1 hour. The clamp was released 0.5 hour after NAC administration. In group 3, rats' left carotid arteries were clamped, and 50 mg/kg ethyl pyruvate was administered intraperitoneally after 1 hour. The clamp was released 0.5 hour after ethyl pyruvate administration. All tissue samples were collected 2.5 hours after reperfusion. Brain tissues were compared histopathologically. RESULTS: A higher percentage of degenerative neurons was determined in group 1 compared with groups 2 and 3 (P values: P(a) = .003 and P(c) = .003, respectively). A significant difference was also observed between groups 2 and 3 (P(b) = .003), with the percentage of degenerative neurons being lower in the NAC group than in the ethyl pyruvate group. CONCLUSION: The use of NAC and ethyl pyruvate reduces injury resulting from ischemia-reperfusion in an experimental animal model of acute ischemic stroke and subsequent reperfusion.

BACKGROUND: Mad honey-related intoxication frequently leads to bradycardia, hypotension, and syncope. Hypothermia is a potentially life-threatening condition if not identified early and treated appropriately. CASE REPORT: Three patients are reviewed. Patient 1 was a 66-year-old man who presented to the emergency department with nausea, vomiting, and faintness beginning 2 h after consuming honey. His temperature was 34°C, his blood pressure was 70/40 mm Hg, and his heart rate was 30 beats/min. Patient 2, a 57-year-old man, presented to the emergency department with headache, feeling cold, and faintness beginning 3 h after consuming honey. His temperature was 35°C, his blood pressure was 60/40 mm Hg, and his heart rate was 46 beats/min. Patient 3 was a 79-year-old woman who presented with nausea, vomiting, and headache 2 h after consuming honey. Her temperature was 35°C, her blood pressure was 70/40 mm Hg, and her heart rate was 40 beats/min. All 3 patients were discharged in good condition after appropriate therapy. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Bradycardia and hypotension are frequently encountered in mad honey intoxication. However, intoxication accompanied by hypothermia has attracted little attention to date.

BACKGROUND AND OBJECTIVE: Intoxications related to "mad honey" are frequently encountered in the Black Sea region of Turkey. Intoxication is established on the basis of whether honey was consumed when history was taken at presentation. The search for a simple and reliable method for showing the grayanotoxins (GTXs) in mad honey in body fluids and in honey consumed by patients is still at the research stage. The purpose of this preliminary study was to investigate GTX levels in blood, urine, and honey consumed by patients with mad honey intoxication and to determine whether there is an association with clinical status. DESIGN AND SETTINGS: This descrptive study was conducted at the department of Emergency Medicine of Karadeniz Technical University Medical Faculty in Turkey. Mad honey, blood, and urine samples were obtained from patients between September 2013 and October 2014. METHODS: Four cases presenting the Department of Emergency Medicine and diagnosed with mad honey intoxication were included in the study. GTX levels in blood, urine, and honey consumed by patients were determined using liquid chromatography-tandem mass spectrometry. RESULTS: Patients' mean blood GTX I level was 30.62 ng/mL, GTX III level 4.917 ng/mL, urine GTX I level 0.447 mg/mL, and GTX III level 1.998 mg/mL. The mean GTX I level in the honey samples consumed was 4.683 mg/g and GTX III level 8.423 mg/g. CONCLUSION: The present study is unique in representing the first time that GTXs have been determined in human body fluids. There is now an urgent need for a large series of studies to provide statistical evidence whether there is a relationship between levels of toxins in human body fluids and clinical picture.

BACKGROUND: Acute mesenteric ischemia (AMI) is a potentially fatal disease. Difficulties in diagnosis make it essential to find early biomarkers. AIMS: This study investigated the diagnostic value of procalcitonin (PCT) levels in AMI. STUDY DESIGN: Animal experimentation. METHODS: Rats were divided into six groups of six animals each. In the experimental group, an experimental ischemia model was established by clamping the superior mesenteric artery from the aortic outflow tract. Blood and tissue specimens were collected from rats in the experimental mesenteric ischemia model at 30 min and 2 and 6 h, and these were compared with specimens from the respective control groups. PCT levels were compared at 30 min and 2 and 6 h. RESULTS: PCT levels were 185.3 pg/mL in the control group and 219.3 pg/mL in the study group, 199.6 pg/mL in the control group and 243.9 pg/mL in the study group, and 201.9 pg/mL in the control group and 286.9 pg/mL in the study group, respectively, at 30 minute, 2 and 6 hours. Significant differences were determined between 6-h control group and ischemia group PCT levels (p=0.005). CONCLUSION: The absence of a significant increase in PCT levels in the early period, while a significant difference was detected in the later period (6 h), shows that PCT levels rise late in mesenteric ischemia and can be a marker in the late period.
ABSTRACT
OBJECTIVE: To investigate the potential diagnostic value of plasma signal peptide, CUB (complement proteins C1r/C1s, Uegf, Bmp1) domain, epidermal growth factor (EGF)-like 1 (SCUBE1) protein in experimentally induced testicular torsion (TT). MATERIALS AND METHODS: In this randomized, controlled, experimental study, 24 mature male Wistar rats were divided into four groups: 2- and 4-hour control (groups I and III, respectively), and 2- and 4-hour torsion (groups II and IV, respectively) groups. Torsion was performed by rotating the left testis 720° clockwise and maintained by fixing the testis. Plasma SCUBE1 levels and histopathological damage scores were compared. RESULTS: There was significantly greater histopathological damage in the 4-hour torsion group compared with the other groups. SCUBE1 levels in this group were also higher than those in the other groups, and the difference was significant. There were significant correlations between histopathological scores and SCUBE1 levels. CONCLUSION: SCUBE1, a novel marker of platelet activation, is elevated in TT. According to our results, platelet activation may play an important pathological role in tissue injury associated with testicular ischemia. Plasma SCUBE1 measurement may have diagnostic, therapeutic, or prognostic value in TT.

OBJECTIVES: The purpose of this study was to evaluate predetermined physical examination and function tests recommended to identify severe injury among patients presenting with wrist injury to the emergency department and to establish a reliable clinical decision rule capable of determining the need for radiography in wrist injuries. MATERIALS AND METHODS: This was a multicenter prospective derivation study of wrist injuries. All patients were assessed in terms of mechanism of trauma, inspection findings, heart rate, sensitivity at palpation, presence of pain with active movement, grasp strength, and functional tests using an examination form under main headings. Sensitivity, specificity, and positive and negative predictive values were expressed for each sign and each examination finding. RESULTS: One hundred nineteen adult patients were enrolled during the 6-month study period. Fracture was identified in 24.3% (n = 29). Presence of pain on the radial deviation, dorsal flexion, distal radioulnar drawer, and axial compression tests exhibited high sensitivity (82.8%, 89.7%, 82.8%, and 86.2%, respectively) and high negative predictive values (88.6%, 81.3%, 87.5%, and 93.6%, respectively) for wrist fracture. Sensitivity of 96.6% was observed when these 4 tests were evaluated together. CONCLUSIONS: The presence of one of these examination findings increases the likelihood of fracture and is adequate to recommend wrist radiography. In addition, there is a strong possibility of radiography being unnecessary if all 4 test results are negative in patients presenting with wrist injury, potentially preventing many nonessential radiographs being performed.
