Background

Ketamine is a cyclohexamine derivative that acts as a noncompetitive N-methyl D-aspartate receptor antagonist. Its use for procedural sedation is recommended by national clinical policy. However, its immunogenic potential is not well documented.

Case Report

We report a case of allergic reaction associated with the administration of intravenous ketamine for procedural sedation in a 16-year-old male. Minutes after administration, the patient developed a morbilliform, erythematous rash that extended to the upper and lower torso and resolved with intravenous diphenhydramine. It is most likely that this allergic reaction was caused by a ketamine-induced histamine release that has been described in vitro.

Why Should an Emergency Physician be Aware of This?

This is the first case report in which ketamine was used as monotherapy in the emergency department for the facilitation of procedural sedation that resulted in an allergic reaction. Supportive measures, including advanced airway procedures and hemodynamic support, may be necessary in more severe anaphylactic cases. Providers should be aware of this potential adverse effect when using ketamine for procedural sedation.  相似文献

Background

Procedural sedation for painful procedures in the emergency department (ED) can be accomplished with various pharmacological agents. The choice of the sedative used is highly dependent on procedure- and patient characteristics and on personal- or local preferences.

Methods

We conducted a multicenter retrospective cohort study of procedural sedations performed in the EDs of 5 hospitals in the Netherlands over a 4 year period to evaluate the efficacy- (success rate of the intended procedure) and safety (incidence of sedation (adverse) events) of propofol sedations compared to midazolam sedations.

Results

A total of 592 ED sedations were included in our study. Patients sedated with propofol (n = 284, median dose 75 mg) achieved a deeper level of sedation (45% vs. 25% deep sedation, p < 0.001), had a higher procedure success rate (92% vs. 81%, p < 0.001) and shorter median sedation duration (10 vs. 17 min, p < 0.001) compared to patients receiving midazolam (n = 308, median dose 4 mg). A total of 112 sedation events were registered for 99 patients. Transient apnea was the most prevalent event (n = 73), followed by oxygen desaturation (n = 18) airway obstruction responsive to simple maneuvers (n = 13) and hypotension (n = 6). Propofol sedations were more often associated with the occurrence of apnea's (20% vs. 10%, p = 0.004), whereas clinically relevant oxygen desaturations (< 90%) were found more often in patients sedated with midazolam (8% vs. 1%, p = 0.001). No sedation adverse events were registered

Conclusion

Propofol is more effective and at least as safe as midazolam for procedural sedation in the ED.  相似文献

Background

Minimizing and preventing adverse events and medical errors in the emergency department (ED) is an ongoing area of quality improvement. Identifying these events remains challenging.

Objective

To investigate the utility of tracking patients transferred to the ICU within 24 h of admission from the ED as a marker of preventable errors and adverse events.

Methods

From November 2011 through June 2016, we prospectively collected data for all patients presenting to an urban, tertiary care academic ED. We utilized an automated electronic tracking system to identify ED patients who were admitted to a hospital ward and then transferred to the ICU within 24 h. Reviewers screened for possible error or adverse event and if discovered the case was referred to the departmental Quality Assurance (QA) committee for deliberations and consensus agreement.

Results

Of 96,377 ward admissions, 921 (1%) patients were subsequently transferred to the ICU within 24 h of ED presentation. Of these 165 (19%) were then referred to the QA committee for review. Total rate of adverse events regardless of whether or not an error occurred was 2.1%, 19/921 (95% CI 1.4% to 3.0%). Medical error on the part of the ED was 2.2%, 20/921 (95% CI 1.5% to 3.1%) and ED Preventable Error in 1.1%, 10/921 (95% CI 0.6% to 1.8%).

Conclusion

Tracking patients admitted to the hospital from the ED who are transferred to the ICU < 24 h after admission may be a valuable marker for adverse events and preventable errors in the ED.  相似文献

Background

Chemical restraint is often required to control agitation induced by methamphetamine. Dexmedetomidine is an α-2 adrenergic receptor agonist with sedative, analgesic, and sympatholytic properties. Its use in the emergency department (ED) to control methamphetamine-induced agitation has not been reported.

Objective

To report two cases of methamphetamine-induced agitation successfully sedated with dexmedetomidine in the ED.

Case Report

The first case was a 42-year-old man with unstable emotion and violent behaviours after smoking methamphetamine. His agitation did not respond to a large cumulative dose of benzodiazepines (10 mg of diazepam and 332 mg of midazolam) administered over 48 h and sedation was achieved with dexmedetomidine. The second case was a 38-year-old methamphetamine user with unstable emotion and recurrent episodes of agitation despite repeated doses of benzodiazepines, whose agitation was controlled with dexmedetomidine infusion.

Discussion

In both cases, dexmedetomidine apparently reduced the dose of benzodiazepines needed to achieve adequate sedation. Transient falls in blood pressure and slowing of the heart rate were noted, which resolved either spontaneously or after reducing the infusion rate without requiring drug treatment.

Conclusion

Dexmedetomidine can be considered as an adjunct for chemical restraint when standard treatment fails to control the agitation induced by methamphetamine, but patient's hemodynamic state should be monitored closely during administration. Its efficacy and safety in the ED warrant further evaluation with prospective controlled trials.  相似文献

Objectives

Errors and adverse events associated with unexpected life-threatening events including unplanned transfer to the intensive care unit (ICU) and unexpected death after emergency department (ED) hospitalization are not well characterized. We performed this study to investigate the role of unexpected life-threatening events as a trigger to capture errors and adverse events for ED patient safety.

Methods

This prospective observational study enrolled adult non-trauma patients with unexpected life-threatening events within 24 h of general ward admission from the ED of a medical center in Taiwan. The period of study was one year (in 2013); the medical records of enrolled patients were reviewed to identify adverse events and errors. We measured the incidence rate of adverse events or errors. Preventability, type, and physical injury severity of adverse events were investigated.

Results

Of 33,224 adult non-trauma ward admissions from the ED, 100 admissions (0.3%) met the study criteria. Incidence rate was 2% and 15% for errors and adverse events, respectively. In admissions involving error, all were preventable and the error type was overlooked of severity. In admissions that involved adverse events, 93.3% were preventable. There were 20% of admissions that resulted in death and 60% developed with severe physical injury. The adverse event types were diagnosis issues (53.3%), management issues (40%), and medication adverse events (6.7%).

Conclusions

Unexpected life-threatening events within 24 h of admission from the ED could be a useful trigger tool to identify preventable adverse events with serious physical injury in ED.  相似文献

Objective

Prehospital personnel who lack advanced airway management training must rely on basic techniques when transporting unconscious trauma patients. The supine position is associated with a loss of airway patency when compared to lateral recumbent positions. Thus, an inherent conflict exists between securing an open airway using the recovery position and maintaining spinal immobilization in the supine position. The lateral trauma position is a novel technique that aims to combine airway management with spinal precautions. The objective of this study was to compare the spinal motion allowed by the novel lateral trauma position and the well-established log-roll maneuver.

Methods

Using a full-body cadaver model with an induced globally unstable cervical spine (C5-C6) lesion, we investigated the mean range of motion (ROM) produced at the site of the injury in six dimensions by performing the two maneuvers using an electromagnetic tracking device.

Results

Compared to the log-roll maneuver, the lateral trauma position caused similar mean ROM in five of the six dimensions. Only medial/lateral linear motion was significantly greater in the lateral trauma position (1.4 mm (95% confidence interval [CI] 0.4, 2.4 mm)).

Conclusions

In this cadaver study, the novel lateral trauma position and the well-established log-roll maneuver resulted in comparable amounts of motion in an unstable cervical spine injury model. We suggest that the lateral trauma position may be considered for unconscious non-intubated trauma patients.  相似文献

Objective

To evaluate the impact of a rivaroxaban discharge initiative on the efficacy and safety of acute venous thromboembolism treatment in emergency department patients.

Practice innovation

Patients discharged on rivaroxaban from the emergency department were provided extensive counseling along with a commercially-available medication dose pack by the ED pharmacist. Patients were contacted by phone until they had obtained outpatient follow-up and remained adherent to anticoagulation beyond the initial first month of treatment.

Methods

In this retrospective chart review over a thirteen month period, efficacy and safety outcomes were compared between patients with intervention versus those who received usual care. Efficacy was defined by reduced 90-day readmission rates due to nonadherence or treatment failure, and improved medication adherence beyond the first month from discharge. Safety was determined by comparing 90-day readmission rates due to bleeding or adverse event.

Results

41 patients received intervention with rivaroxaban, and 34 patients received usual care, with 76% prescribed rivaroxaban and remaining patients started on enoxaparin alone (6%) or enoxaparin plus warfarin (18%). Improved treatment efficacy in the intervention group was not found to be statistically significant. Safety outcomes were similar between the two groups.

Conclusion

Home treatment of acute VTE, facilitated by medication dose pack, is a promising tactic to ensure both immediate and long-term treatment efficacy and safety. Further studies are warranted to demonstrate clinical superiority of this intervention.  相似文献

Background

Disparities exist in the care children receive in the emergency department (ED) based on their insurance type. It is unknown if these differences exist among children transferred from outside EDs to pediatric tertiary care EDs.

Objective

To compare reasons for transfer and services received at pediatric tertiary care EDs between children with private and public insurance.

Methods

We performed a secondary analysis of a multicenter survey of ED providers transferring patients to pediatric tertiary care EDs in three major U.S. cities. Risk differences (RD) and 95% confidence intervals (CI) were calculated to compare reasons for transfer and care received at pediatric tertiary care EDs based on insurance type.

Results

There were 561 surveys completed by transferring providers describing reasons for transfer to pediatric tertiary care EDs with 52.2% of patients with private insurance and 47.8% with public insurance. We found no significant differences between privately and publicly insured children in reason for transfer for subspecialty consultation or need for admission. We found no significant differences in frequency of admission, radiologic studies, or ED procedures at the receiving facilities. However, a greater proportion of privately insured children had a subspecialty consultation at receiving facilities compared to publicly insured children (RD 9.7, 95% CI 2.0 to 17.4).

Conclusions

Transferred pediatric patients with private insurance were more likely to have subspecialty consultations than children with public insurance. Further studies are needed to better characterize the interplay between patients' insurance type and both the request for, and the provision of, ED subspecialty consultations.  相似文献

Background

Few studies were performed to compare ultrasound guided brachial plexus block with procedural sedation for reduction of shoulder dislocations in the Emergency Department (ED). This study was done to provide further evidence regarding this comparison.

Methods

This was a randomized clinical trial performed on patients presenting with anterior shoulder dislocations to the emergency department of an academic level 2 trauma center. Exclusion criteria were any contraindications to the drugs used, any patient which may not be potentially assigned into both groups because of an underlying medical condition, presence of neurovascular compromise related to the dislocation, presence of concomitant fractures, and patient refusal to participate in the study. Patients were randomly assigned into the Procedural Sedation and Analgesia (PSA) group with propofol and fentanyl or ultrasound guided Inter-Scalene Brachial Plexus Block (ISBPB) with lidocaine and epinephrine.

Results

A total of 60 patients (30 in each group) were included in the study. The emergency room length of stay was significantly lower in the ISBPB group, with mean (SD) values of 108.6 (42.1) vs. 80.2 (25.2) minutes (p = 0.005). However, pain scores in the PSA group during reduction showed advantage over ISBPB [0.38 vs. 3.43 (p < 0.001)]. Moreover, patient satisfaction was higher with PSA (p < 0.001).

Conclusion

Using ISBPB for reduction of anterior shoulder dislocations takes less time to discharge and may make it more feasible in conditions mandating faster discharge of the patient. However, since pain scores may be lower using PSA, this method may be preferred by many physicians in some other situations.  相似文献

Introduction

Procedural sedation and analgesia (PSA) are frequently used for fracture reduction in pediatric emergency departments (ED). Combining intranasal (IN) fentanyl with inhalation of nitrous oxide (N2O) allow for short recovery time and obviates painful and time-consuming IV access insertions.

Methods

We performed a bicentric, prospective, observational cohort study. Patients aged 4–18 years were included if they received combined PSA with IN fentanyl and N2O for the reduction of mildly/moderately displaced fracture or of dislocation. Facial Pain Scale Revised (FPS-R) and Face, Leg, Activity, Cry, Consolability (FLACC) scores were used to evaluate pain and anxiety before, during and after procedure. University of Michigan Sedation Score (UMSS), adverse events, detailed side effects and satisfaction of patients, parents and medical staff were recorded at discharge. A follow up telephone call was made after 24–72 h.

Results

90 patients were included. There was no difference in FPS-R during the procedure (median score 2 versus 2), but the FLACC score was significantly higher as compared to before (median score 4 versus 0, Δ 2, 95% CI 0, 2). Median UMSS was 1 (95% CI 1, 2). We recorded no serious adverse events. Rate of vomiting was 12% (11/84). Satisfaction was high among participants responding to this question 85/88 (97%) of parents, 74/83 (89%) of patients and 82/85 (96%) of physicians would want the same sedation again.

Conclusion

PSA with IN fentanyl and N2O is effective and safe for the reduction of mildly/moderately displaced fracture or dislocation, and has a high satisfaction rate.  相似文献

Background

Headache is one of the most common reasons for patients to seek care in emergency departments. While the administration of intravenous fluids is frequently recommended for emergency department patients with migraine, the epidemiology of the use of this intervention is unknown.

Objectives

To describe the epidemiology of intravenous fluid use in emergency department patients with headache.

Methods

This retrospective study utilized the 2011 US National Hospital Ambulatory Medical Survey, a multi-stage weighted survey providing nationally representative estimates of ED visits. Patients with chief complaints of non-traumatic headache or migraine headache were included. We determined the frequency of intravenous fluid administration among patients presenting with headache, and among specific subgroups including those with migraine headache.

Results

There were 1251 sample cases representing 5,981,000 visits for a chief complaint of headache. Intravenous fluids were administered at 40% (95% CI 35–44%) of these visits. Among the 222 migraine cases, 47% (95% CI 39–56%) received fluids. Fluids were commonly administered regardless of pain severity, and fluid administration was not significantly associated with pain severity among patients diagnosed with migraine (p = 0.39). After adjusting for patient characteristics, ED visit duration remained greater for patients receiving fluids than for those who did not among both patients with a headache complaint and among those with a diagnosis of migraine headache.

Conclusions

Despite a lack of efficacy data, patients treated in United States EDs for headache frequently receive IV fluids. Studies are needed to determine the efficacy of this basic treatment intervention.  相似文献

Introduction

In the difficult airway, the intubation skills are critically important. In selected cases, particularly in airway edema, laryngeal or tongue edema, endotracheal intubation can turn out very difficult, and repeated attempts may even worsen the airway edema, causing trauma and bleeding, and finally leading to complete airway obstruction and inability to ventilate the patient.

Aim of the study

The aim of the study was to compare the efficacy of endotracheal intubation performed by novice physicians using a standard Macintosh laryngoscope and an Intubrite videolaryngoscope.

Material and methods

The study was designed as a prospective, randomized, crossover, simulation study and continues our research assessing the effectiveness of selected endotracheal intubation techniques in prehospital settings. All participants were experienced with the Macintosh direct laryngoscope but remained novice to videolaryngoscopy. Instructions on the correct use of the Macintosh and Intubrite laryngoscopes were given before the procedure, and all the 30 novice physicians were allowed to practice at least 10 times before the study on manikin with normal airways. We employed an airway manikin (Trucorp Airsim Bronchi; Trucorp Ltd., Belfast, Northern Ireland) to simulate difficult airway, with was obtained by inflating the tongue with 50 mL of air. The participants were asked to perform tracheal intubation using an endotracheal tube with 7.5 mm of internal diameter (Portex; Smiths Medical, Hythe, UK) through the vocal cords, applying either a conventional Macintosh laryngoscope with a size 3 blade (MAC; Mercury Medical, Clearwater, FL, USA) or the Intubrite videolaryngoscope, also with a Macintosh No. 3 blade (INT; Intubrite Llc, Vista, CA, USA). In both intubation techniques, a guide stylet (Rusch Inc., Duluth, GA, USA) was introduced into the endotracheal tube in order to obtain a C-shape curve to facilitate tracheal intubation. Each participating physician was randomly assigned to three attempts of tracheal intubation with each device.

Results

The effectiveness of the first intubation attempt using MAC and INT was 63.6% and 53.4%, respectively (p = 0.023), and the total percentage of intubation was 100% for both methods. The median time to intubation was 29.5 (interquartile range [IQR], 27–35.5) s with MAC, and 229 (IQR, 25.5–37) s with INT. The total of 24 physicians out of all study participants would choose MAC as a device to intubate with in real terms, while only 6 physicians would choose INT.

Conclusions

During the simulation study, the novice physicians were able to perform endotracheal intubation at the same time using both the Macintosh and Intubrite videolaryngoscope. However, the efficacy of the first intubation attempt was higher for MAC. Further studies are needed to confirm the results.  相似文献

Background

In evaluating patients with chest pain, emergency department observation units (EDOUs) may use a staffing model in which emergency physicians determine patient testing (EP model) or a model similar to a chest pain unit (CPU) in which cardiologists determine provocative testing (CPU model).

Methods

We performed a prospective study with 30-day telephone follow-up for all chest pain patients placed in our EDOU. Halfway through the study period, our EDOU transitioned from an EP model to a CPU model. We compared provocative testing rates and outcomes between the 2 models.

Results

Over the 34-month study period, our EDOU evaluated 1190 patients for chest pain. Patients placed in the EDOU during the 17-month CPU model were more likely to be moderate risk (Thrombolysis in Myocardial Infarction score 3-5) than those during the 17-month EP model: 24.9% vs 18.8%, P = .011. Despite this difference, rates of provocative testing (stress testing or coronary computed tomography) were lower during the CPU model: 47.1% vs 56.5%, P = .001. This reduction was particularly evident among low-risk patients (Thrombolysis in Myocardial Infarction score 0-2): 49.8% vs 58.1%, P = .011. Rates of myocardial infarction, percutaneous coronary intervention, or coronary artery bypass graft were similar between the 2 groups (2.8% vs 3.2%, P = .140). We noted no significant events or missed diagnoses in either group during the 30-day follow-up.

Conclusion

An EDOU model that used mandatory cardiology consultation resulted in decreased provocative testing, particularly among low-risk chest pain patients. Future research should explore the cost-effectiveness of this model.  相似文献

Introduction

In emergency medicine (EM), patient care documentation serves many functions, including supporting reimbursement. In addition, many electronic health record systems facilitate automatically populating certain data fields. As a result, in the academic model, the attending's note may now more often recapitulate many of the same elements found in the resident's or physician assistant's (PA) note. We sought to determine the value of additional attending documentation, and how often the attending documentation prevented a downcoding event.

Methods

This retrospective, cross-sectional study was exempted by the Institutional Review Board. We randomly reviewed 10 charts for each attending physician during the study period. Outcome measures included the frequency of prevented downcoding events, and the difference in this incidence between residents and PAs.

Results

530 charts were identified, but 6 were excluded as these patients left without being seen. 524 charts remained, of which 286 (45%) notes were written by residents and 238 (55%) notes were written by PAs. Attending documentation prevented 16 (3%) downcoding events, of which 11 were in patient encounters documented by residents and 5 were in encounters documented by PAs (p = 0.057).

Conclusions

In this study of an academic medical center documentation model with an EHR, EM attending documentation of the history of present illness, review of systems, physical exam, and medical decision making portions prevented downcoding in a small number of cases. In addition, there was no significant difference in the incidence of prevented downcoding events between residents and PAs.  相似文献

Introduction

Delay in current nucleic acid amplification testing for Neisseria gonorrhoeae and Chlamydia trachomatis has led to recommendations for presumptive treatment in patients with concern for infection and unreliable follow-up. In the urban setting, it is assumed that many patients have unreliable follow-up, therefore presumptive therapy is thought to be used frequently. We sought to measure the frequency of disease and accuracy of presumptive treatment for these infections.

Methods

This was an observational cohort study performed at an urban academic Level 1 trauma center ED with an annual census of 95,000 visits per year. Testing was performed using the APTIMA Unisex swab assay (Gen-Probe Incorporated, San Diego, CA). Presumptive therapy was defined as receiving treatment for both infections during the initial encounter without confirmation of diagnosis.

Results

A total of 1162 patients enrolled. Infection was present in 26% of men, 14% of all women and 11% of pregnant women. Despite high frequency of presumptive treatment, > 4% of infected patients in each category went untreated.

Conclusion

Inaccuracy of presumptive treatment was common for these sexually transmitted infections. There is an opportunity to improve diagnostic accuracy for treatment.  相似文献

Study objectives

Morphine is the reference treatment for severe acute pain in an emergency department. The purpose of this study was to describe and analyse opioid-related ADRs (adverse drug reactions) in a large cohort of emergency department patients, and to identify predictive factors for those ADRs.

Methods

In this prospective, observational, pharmaco-epidemiological international cohort study, all patients aged 18 years or older who were treated with morphine were enrolled. The study was done in 23 emergency departments in the US and France. Baseline numerical rating scale score and initial and total doses of morphine titration were recorded. Logistic regression analysis was used to study the effects of demographic, clinical and medical history covariates on the occurrence of opioid-induced ADRs within 6 h after treatment.

Results

A total of 1128 patients were included over 10 months. Median baseline initial pain scores were 8/10 (7–10) versus 3/10 (1–4) after morphine administration. Median titration duration was 10 min (IQR, 1–30). The occurrence of opioid-induced ADRs was 25% and 2% were serious. Patients experienced mainly nausea and drowsiness. Medical history of travel sickness (odds ratio [OR], 1.7; 95% confidence interval [CI], 1.01–2.86) and history of nausea or vomiting post morphine (OR, 3.86; 95% CI, 2.29–6.51) were independent predictors of morphine related ADRs.

Conclusion

Serious morphine related ADRs are rare and unpredictable. Prophylactic antiemetic therapy could be proposed to patients with history of travel sickness and history of nausea or vomiting in a postoperative setting or after morphine administration.  相似文献

Objectives

Small bowel obstructions (SBOs) occur 300,000 times annually leading to $1.3 billion in cost. Approximately 20% of patients require a laparotomy to manage the obstruction and either prevent or treat intestinal ischemia. Early management may play a role in reducing these complications. Nasogastric decompression is commonly used for early management. Our primary objective was to determine if NGD was associated with lower rates of surgery, bowel ischemia or length of stay.

Methods

We retrospectively enrolled 181 ED patients with SBO from 9/2013 to 9/2015 in order to determine if nasogastric decompression was associated with a reduction in rates of surgery, bowel ischemia or hospital length of stay.

Results

Our subject population was 46% female, median age of 60.27% of patients received surgery. Nasogastric decompression was used in 51% of patients. There was no association with a reduction in rates of surgery (p = 0.20) or bowel resection (p = 0.41) with patients receiving Nasogastric decompression, and no difference in baseline characteristics. Nasogastric decompression was associated with a two-day increase in hospital length of stay. Factors that were significantly associated with surgical exploration of SBO were: female (OR 2.32 (95% CI: 1.01–5.31)) and “definite SBO” on CT (OR 3.29 (95% CI: 1.18–9.20)). Abnormal vital signs, obstipation, and lab values were not predictors of surgery.

Conclusion

Nasogastric decompression is not associated with a reduction in need for surgery or bowel resection, but is associated with a 2-day increase in median LOS. Women were more likely to receive surgery than men.  相似文献

Objective

Sedative-hypnotic medications (e.g., Benzodiazepines [BZDs] and non-benzodiazepine receptor agonists [nBZRAs]) are associated with adverse events, especially in the elderly, that may require emergency department (ED) treatment. This study assessed outcomes from ED visits attributed to BZDs and/or nBZRAs, and variations in these associations by age group.

Methods

Data came from the 2004–2011 waves of the Drug Abuse Warning Network (DAWN). Visits were categorized as involving: (1) BZDs-only, (2) nBZRAs-only, (3) combination of BZDs and nBZRAs, or (4) any other sedative-hypnotic medication. DAWN also recorded the disposition (i.e., outcome) of the visit. Analyses focused on outcomes indicating a serious disposition defined as hospitalization, patient transfer or death. Using logistic regression, the association of BZD and nBZRA use with visit disposition was assessed after applying sample weights so as to be nationally representative of ED visits in the United States involving medications or illicit substances.

Results

Nineteen percent of visits involving other sedative-hypnotics, 28% involving BZDs-only, 20% involving nBZRAs-only and 48% involving a combination of BZDs and nBZRAs resulted in a serious disposition. Compared to visits involving other sedative-hypnotics, visits involving BZDs-only had 66% greater odds (Odds Ratio [OR] = 1.66, 95% Confidence Interval [CI] = 1.37–2.01), and visits involving a combination of BZDs and nBZRAs had almost four times increased odds of a serious disposition (OR = 3.91, 95% CI = 2.38–6.41). Results were similar across age groups.

Conclusions

Findings highlight the need for clinical and regulatory initiatives to reduce BZD use, especially in combination with nBZRAs, and to promote treatment with safer alternatives to these medications.  相似文献

Background

Chest radiography is the initial choice for thoracic imaging. However, the wide availability of computed tomography (CT) has led to a substantial increase in its use in the emergency department (ED). We evaluated the utility of chest CT after a chest X-ray in patients presenting to the ED with non-traumatic thoracic emergencies, and determined if the diagnosis and management decision changed after CT.

Methods

The study enrolled 500 consecutive patients with both chest X-rays and CT who presented to the ED with non-traumatic complaints. Chest X-rays and CT images obtained within 12 h before any definitive treatment were randomly evaluated in consensus by two radiologists blinded to the clinical information.

Results

The chest X-ray and CT image findings were concordant in 49.2% of the 500 patients and this concordance was negatively correlated with patient age. Leading diagnosis and management decisions based on the chest radiograph changed after CT in 35.4% of the study group and this finding was also correlated with age. In 55% of 205 patients, pneumonic infiltrations were undiagnosed with radiography. Pulmonary edema was the most specific (93.3%) and sensitive (85.4%) radiography finding. Posteroanterior chest radiographs taken in the upright position had higher concordance with CT than anteroposterior (AP) radiographs taken in the supine position.

Conclusions

Chest CT may be an appropriate imaging choice in patients presenting to the ED for non-traumatic reasons, particularly for elderly patients and when the radiograph is taken with the AP technique in a supine position.  相似文献
