Association between the quantity of stroke care units and the complement of neurosurgical and neurology specialists in Japan: A retrospective study

BackgroundStroke care units provide advanced intensive care for unstable patients with acute stroke. We conducted a survey to clarify the differences in stroke care units between urban and regional cities and the relationship between the number of stroke care unit beds and neurologists. MethodsThis retrospective observational study was conducted in 2,857 and 4,184 hospitals in urban and regional cities in 47 provinces of Japan, respectively, between January 2020 and August 2023. Tokyo and ordinance-designated cities in provinces were defined as urban cities, and those without such cities were defined as regional cities. The primary endpoint was the presence or absence of a stroke care unit. ResultsMultiple linear regression analysis revealed that the presence of stroke care units was significantly associated with the number of neurosurgical specialists. Receiver operating characteristic curve analysis was performed to predict the number of personnel required for stroke care unit installation based on the number of neurosurgical specialists. The area under the receiver operating characteristic curve, Youden index, sensitivity, and specificity were 0.721, 0.483, 0.783, and 0.700, respectively. ConclusionsOur study underscores the indispensability of SCUs in stroke treatment, advocating for a strategic allocation of medical resources, heightened accessibility to neurosurgical specialists, and a concerted effort to address geographic and resource imbalances. The identified cutoff value of 8.99 neurosurgical specialists per 100,000 population serves as a practical benchmark for optimizing SCU establishment, thereby potentially mitigating stroke-related mortality.

Metformin-Associated Lactic Acidosis: Which Elimination Therapy to Use in Case of Haemodynamic Instability? A Retrospective Cohort Study

Introduction: Metformin, a commonly used oral antihyperglycemic drug, poses a rare risk related to the development of metformin-associated lactic acidosis (MALA). The Extracorporeal Treatments in Poisoning (EXTRIP) group recommended intermittent haemodialysis (IHD) as a primary elimination therapy in case of severe metformin poisoning. However, in haemodynamically unstable patients, our previous observations suggested that continuous venovenous haemofiltration (CVVH) might be more effective. This retrospective cohort study aimed to contribute evidence on the use of IHD and CVVH in patients with severe MALA, particularly in haemodynamically unstable patients. Methods: Data from January 2015 to December 2020 were collected from the Leuven University Hospital. Two separate search methods, based on hospital activity records and laboratory criteria, were used to identify patients with MALA. Patients diagnosed with MALA, receiving extracorporeal treatment within 24 h of admission, were included. Patients were categorized into the IHD and CVVH groups. Patient characteristics, treatment details, and outcomes were analysed. Results: Among 358,148 patient records, 35 MALA cases were identified. IHD was chosen as the initial elimination technique in 13 cases, whereas 22 patients were first commenced on CVVH. Patients treated with CVVH were sicker, had more comorbidities and had higher ventilation and vasopressor requirements. CVVH group had longer vasopressor use, longer ICU stays, and higher in-hospital mortality. Discussion: CVVH rather than IHD seems to be the preferred elimination technique in the more critically ill patients with MALA. Due to its retrospective design, this study failed to identify the superior elimination technique in terms of efficacy. Poorer outcomes in the CVVH group are likely attributed to the severity of illness rather than the inferiority of the elimination therapy. We acknowledge the diagnostic challenges regarding MALA. Using metformin assays could be beneficial in managing these patients. Conclusions: This study suggests clinicians’ preference for CVVH in severe cases of MALA with haemodynamic instability.

Are We Always Right? Evaluation of the Performance and Knowledge of the Passive Leg Raise Test in Detecting Volume Responsiveness in Critical Care Patients: A National German Survey.

Background: In hemodynamically unstable patients, the passive leg raise (PLR) test is recommended for use as a self-fluid challenge for predicting preload responsiveness. However, to interpret the hemodynamic effects and reliability of the PLR, the method of performing it is of the utmost importance. Our aim was to determine the current practice of the correct application and interpretation of the PLR in intensive care patients. Methods: After ethical approval, we designed a cross-sectional online survey with a short user-friendly online questionnaire. Using a random sample of 1903 hospitals in Germany, 182 hospitals with different levels of care were invited via an email containing a link to the questionnaire. The online survey was conducted between December 2021 and January 2022. All critical care physicians from different medical disciplines were surveyed. We evaluated the correct points of concern for the PLR, including indication, contraindication, choice of initial position, how to interpret and apply the changes in cardiac output, and the limitations of the PLR. Results: A total of 292 respondents participated in the online survey, and 283/292 (97%) of the respondents completed the full survey. In addition, 132/283 (47%) were consultants and 119/283 (42%) worked at a university medical center. The question about the performance of the PLR was answered correctly by 72/283 (25%) of the participants. The limitations of the PLR, such as intra-abdominal hypertension, were correctly selected by 150/283 (53%) of the participants. The correct effect size (increase in stroke volume ≥ 10%) was correctly identified by 217/283 (77%) of the participants. Conclusions: Our results suggest a considerable disparity between the contemporary practice of the correct application and interpretation of the PLR and the practice recommendations from recently published data at German ICUs.

Evolution in liver trauma management: a single centre experience

Objectives Liver trauma is common and can be treated non-operatively, through radiological embolisation, or surgically. Non-operative management (NOM) is preferred when possible, but specific criteria remain unclear. This retrospective study at a level I trauma centre assessed the evolution and outcomes of liver injury management over more than 20 years. Methods Data from January 1996 to June 2020 were analysed for liver trauma cases. Variables were evaluated, including the type of injury, diagnostic modalities, liver injury grade, transfer from other hospitals, treatment type, and length of hospital stay. Outcomes were assessed using soft (hospitalisation time and intensive care unit stay) and hard (mortality) endpoints. Results In total 406 patients were analysed, of which 375 (92.4%) had a blunt and 31 (7.6%) a penetrating liver trauma. Approximately one-third (31.2%) were hemodynamically unstable, although 78.8% had low-grade liver lesions. The initial treatment was non-operative in 72.9% of the patients (68.5% conservative, 4.4% interventional radiology). Blunt trauma was treated by surgery in 23.2% of the patients, while 74.2% in case of penetrating trauma. Overall mortality was 11.1% including death caused by associated lesions. The 24-h mortality was 5.7%. Indication for surgical treatment was determined by hemodynamic instability, high grade liver lesion, penetrating trauma, and associated lesions. Conclusions Although the role of surgery in liver trauma management has strongly diminished over recent decades, hemodynamically unstable patients, high-grade lesions, penetrating trauma, and severe associated lesions are the main indications for surgery. In other situations, NOM by full conservative therapy or radiological embolisation seems effective.

IPad-Based Neurocognitive Testing (ImPACT-QT) in Acute Adult Mild Traumatic Brain Injury/Concussion: Study on Practicality and Bedside Cognitive Scores in a Level-1 Trauma Center.

There lacks rapid standardized bedside testing to screen cognitive deficits following mild traumatic brain injury (mTBI). Immediate Post-Concussion Assessment & Cognitive Testing-Quick Test (ImPACT-QT) is an abbreviated-iPad form of computerized cognitive testing. The aim of this study is to test ImPACT-QT utility in inpatient settings. We hypothesize ImPACT-QT is feasible in the acute trauma setting. Trauma patients ages 12-70 were administered ImPACT-QT (09/2022-09/2023). Encephalopathic/medically unstable patients were excluded. Mild traumatic brain injury was defined as documented-head trauma with loss-of-consciousness <30 minutes and arrival Glasgow Coma Scale 13-15. Patients answered Likert-scale surveys. Bivariate analyses compared demographics, attention, motor speed, and memory scores between mTBI and non-TBI controls. Multivariable logistic regression assessed memory score as a predictor of mTBI diagnosis. Of 233 patients evaluated (36 years [IQR 23-50], 71% [166/233] female), 179 (76%) were mTBI patients. For all patients, mean test-time was 9.3 ± 2 minutes with 93% (73/76) finding the test "easy to understand." Mild traumatic brain injury patients than non-TBI control had lower memory scores (25 [IQR 7-100] vs 43 [26-100], P = .001) while attention (5 [1-23] vs 11 [1-32]) and motor score (14 [3-28] vs 13 [4-32]) showed no significant differences. Multivariable-regression (adjustment: age, sex, race, education level, ISS, and time to test) demonstrated memory score predicted mTBI positive status (OR .96, CI .94-.98, P = .004). Immediate Post-Concussion Assessment & Cognitive Testing-Quick Test is feasible in trauma patients. Preliminary findings suggest acute mTBIs have lower memory but not attention/motor scores vs non-TBI trauma controls.

Outcomes of mitral valve transcatheter edge-to-edge repair for patients with hemodynamic instability: A systematic review and meta-analysis

BackgroundThe outcomes after mitral valve transcatheter edge-to-edge repair (M-TEER) for the patients with severe mitral regurgitation (MR) in hemodynamically unstable conditions, such as cardiogenic shock, still remain unclear. We aimed to integrate previous publications regarding M-TEER indicated for life-threatening conditions and indirectly particularly compared the short-term outcomes thereof, with that of other treatments. MethodsWe systematically searched the PubMed, Cochrane, and MEDLINE databases for studies from inception to June 2023, regarding M-TEER in patients with hemodynamic instability and severe MR. The primary outcomes analyzed included the in-hospital and 30-day mortality rates, and peri-procedural complications. ResultsOf the initial 820 publications, we conducted a meta-analysis of a total of 25 studies. The relative risk of moderate-to-severe or severe MR was 0.13 (95 % confidence interval [CI]: 0.10–0.18, I2 = 45.2 %). The pooled in-hospital and 30-day mortality rates were 11.8 % (95 % CI: 8.7–15.9, I2 = 96.4 %) and 14.1 % (95 % CI: 10.9–18.3, I2 = 35.5 %), respectively. The 30-day mortality rate was statistically significantly correlated with the residual moderate-to-severe or severe MR, as per the meta-regression analysis (coefficient β = 3.48 [95 % CI: 0.99–5.97], p = 0.006). Regarding peri-procedural complications, the pooled rates of a stroke or transient ischemic attack, life-threatening or major bleeding, acute kidney injury, and peri-procedural mitral valve surgery were 2.3 % (95 % CI: 1.9–2.6), 7.6 % (95 % CI: 6.8–8.5), 32.9 % (95 % CI: 31.6–34.3), and 1.0 % (95 % CI: 0.8–1.3), respectively. ConclusionsThis meta-analysis demonstrates that the relatively higher rates of procedural complications were observed, nevertheless, M-TEER can potentially provide favorable short-term outcomes even in hemodynamically unstable patients.

Pulmonary Embolism: An Update Based on the Revised AWMF-S2k Guideline.

Pulmonary embolism (PE) is the third most common acute cardiovascular disease. The risk of PE increases with age and mortality is high. Patients are stratified into hemodynamically stable versus unstable patients, as this has important implications for diagnosis and therapy. Since clinical signs and symptoms of acute PE are nonspecific, the clinical likelihood of PE is estimated to guide diagnostic pathways. D-dimer testing is performed in hemodynamically stable patients with low or intermediate probability of PE and the visualization of thromboembolism and its sequelae is commonly achieved with computed tomography pulmonary angiography (CTPA), supplemented by ultrasound techniques. With confirmed PE, another risk stratification estimates disease severity and defines intensity and setting of the ensuing treatment. The therapeutic spectrum ranges from outpatient treatment with initial oral anticoagulation to thrombolytic or interventional treatment in the intensive care unit or catheterization laboratory. In single cases, even acute surgical thrombectomy is attempted.

Abdominal trauma: Clinical monitoring, an overlooked yet essential ally

Abdominal traumas are a frequent emergency and are associated with significant morbidity and mortality in spite of improved recongnition, diagnosis and management. Trauma is the second largest cause of disease accounting for 16% of global burden. Approach to trauma should be systemic and prioritized. The hemodynamically unstable patient should undergo expedient sonography to rule out abdominal haemorrhage. The use of computer tomography (CT) in this difficult patient group is also currently evaluated; however it takes specific amendments to the protocol and institution. In the hemodynamically stable patient however, computed tomography is the modality of choice to evaluate the injured abdomen. Non operative treatment can be successful in up to 80% of selected cases. This article objective the interest of close monitoring in the management of abdominal trauma, this monitoring reduces the rate of surgical intervention in clinically stable patients and also allows to propose a delayed surgery if the patient’s clinical or radiological status changes during monitoring.

Damage Control Interventional Radiology in Liver Trauma: A Comprehensive Review.

The liver is the second most common solid organ injured in blunt and penetrating abdominal trauma. Non-operative management (NOM) has become the standard of care for liver injuries in stable patients, where transarterial embolization (TAE) represents the main treatment, increasing success rates and avoiding invasive surgical procedures. In hemodynamically (HD) unstable patients, operative management (OM) is the standard of care. To date, there are no consensus guidelines about the endovascular treatment of patients with HD instability or in ones that responded to initial infusion therapy. A review of the literature was performed for published papers addressing the outcome of using TAE as the primary treatment for HD unstable/transient responder trauma liver patients with hemorrhagic vascular lesions, both as a single treatment and in combination with surgical treatment, focusing additionally on the different definitions used in the literature of unstable and transient responder patients. Our review demonstrated a good outcome in HD unstable/transient responder liver trauma patients treated with TAE but there still remains much debate about the definition of unstable and transient responder patients.

Pelvic packing or endovascular interventions: Which should be given priority in managing hemodynamically unstable pelvic fractures? A systematic review and a meta-analysis

BackgroundPelvic fractures in trauma patients can be associated with substantial massive hemorrhage. Hemostasis interventions mainly consist of pelvic packing (PP) and endovascular intervention (EI), such as angiography-embolization (AE) and resuscitative endovascular balloon occlusion of the aorta (REBOA). Whether PP or EI should be prioritized for the management of hemodynamic unstable patients with pelvic fractures remains under debate. This meta-analysis aimed to establish the evidence-based recommendations for the management of hemodynamic unstable patients. Materials and methodsPubMed, CENTRAL, and EMBASE databases were searched for articles published from January 1, 2000 to January 31, 2023. Eligible studies, such as retrospective cohort studies, propensity score matching studies, prospective cohort studies, observational cohort studies, quasi-randomized clinical trials evaluating PP and EI (AE or REBOA) for the management of patients with hemodynamically unstable pelvic fractures, were included. Mean Difference (MD), relative risk (RR), and 95 % confidence intervals (CI) were calculated using fixed- or random-effects models depending on the heterogeneity of included trials. We compared the effectiveness of the two methods in terms of mortality, unstable fracture pattens, injury severity score (ISS), systolic blood pressure (SBP), lactate (LA), base deficiency (BE), hemoglobin preoperatively, blood transfusion requirement, the time to and of operation, complications. ResultsOverall, 15 trials enrolling 1136 patients were analyzed, showing a total mortality rate of 28.4 % (323/1136). No effect of PP preference on the ISS (PP 36.4 ± 10.4 vs. EI 34.5 ± 12.7), SBP (PP 81.1 ± 24.3 mmHg vs. EI 94.2 ± 32.4 mmHg), LA (PP 4.66 ± 2.72 mmol/L vs. 4.85 ± 3.45 mmol/L), BE (PP 8.14 ± 5.64 mmol/L vs. 6.66 ± 5.68 mmol/L), and unstable fracture patterns (RR = 1.10, 95 % CI [0.63, 1.92]) was observed. PP application was associated with lower preoperative hemoglobin level (PP 8.11 ± 2.28 g/dL vs. EI 8.43 ± 2.43 g/dL, p < 0.05), more preoperative transfusion (MD = 2.53, 95 % CI [0.01, 5.06]), less postoperative transfusion within the first 24 h (MD = −1.09, 95 % CI [−1.96, −0.22]), shorter waiting time to intervention (MD = −0.93, 95 % CI [−1.54, −0.31]), and shorter operation time of intervention (MD = −0.41, 95 % CI [−0.52, −0.30]). PP had lower mortality rate owing to uncontrolled hemorrhage in the acute phase (RR = 0.41, 95 % CI [0.22, 0.79]). There was neither difference in mortality due to other complications (RR = 1.60, 95 % CI [0.79, 3.24]), nor in total mortality (RR = 0.92, 95%CI [0.49, 1.74]) (p > 0.05). ConclusionsPP showed advantages of reducing the amount of postoperative transfusion, shortening the time of waiting and operating, and decreasing mortality due to uncontrolled hemorrhage in the acute phase without raising the odds of mortality due to complications. PP, a reliable hemostatic method, should be prioritized for resuscitating most pelvic fractures with hemodynamically unstable, especially in case of bleeding from veins and fracture sites, as well as inadequate EI.

An International Survey of the Management of Atrial Fibrillation in Critically Unwell Patients.

To evaluate the current management of new-onset atrial fibrillation and compare differences in practice regionally. Cross-sectional survey. United States, Canada, United Kingdom, Europe, Australia, and New Zealand. Critical care attending physicians/consultants and fellows. None. A total of 386 surveys were included in our analysis. Rate control was the preferred treatment approach for hemodynamically stable patients (69.1%), and amiodarone was the most used antiarrhythmic medication (70.9%). For hemodynamically unstable patients, a strategy of electrolyte supplementation and antiarrhythmic therapy was most common (54.7%). Physicians responding to the survey distributed by the Society of Critical Care Medicine were more likely to prescribe beta-blockers as a first-line antiarrhythmic medication (38.4%), use more transthoracic echocardiography than respondents from other regions (82.4%), and more likely to refer patients who survive their ICU stay for cardiology follow-up if they had new-onset atrial fibrillation (57.2%). The majority of survey respondents (83.0%) were interested in participating in future studies of atrial fibrillation in critically ill patients. Significant variation exists in the management of new-onset atrial fibrillation in critically ill patients, as well as geographic variation. Further research is necessary to inform guidelines in this population and establish if differences in practice impact long-term outcomes.

Development of a Probabilistic Boolean network (PBN) to model intraoperative blood pressure management

BackgroundBlood pressure is a vital sign for organ perfusion that anesthesiologists measure and modulate during surgery. However, current decision-making processes rely heavily on clinicians’ experience, which can lead to variability in treatment across surgeries. With the advent of machine learning, we can now create models to predict the outcomes of interventions and guide perioperative decision-making. The first step in this process involves translating the clinical decision-making process into a framework understood by an algorithm. Probabilistic Boolean networks (PBNs) provide an information-rich approach to this problem. A PBN trends toward a steady state, and its decisions are easily understood via its Boolean predictor functions. We hypothesize that a PBN can be developed that corrects hemodynamic instability in patients by selecting clinical interventions to maintain blood pressure within a given range. MethodsData on patients over the age of 65 undergoing surgery with general anesthesia from 2018 to 2020 were drawn from the UF Health PRECEDE data set with IRB approval (IRB201700747). Parameters examined included heart rate, blood pressure, and frequency of medications given 15 min after anesthetic induction and 15 min before awakening. The medication frequency data were truncated into a 66/33 split for the training and validation set used in the PBN. The model was coded using Python 3 and evaluated by comparing the frequency of medications chosen by the program to the values in the testing set via linear regression analysis. ResultsThe network developed successfully models a hemodynamically unstable patient and corrects the imbalance by administering medications. This is evidenced by the model achieving a stable, steady state matrix in all iterations. However, the model's ability to emulate clinical drug selection was variable. It was successful with its use of vasodilator selection but struggled with the appropriate selection of vasopressors. ConclusionsThe PBN has demonstrated the ability to choose appropriate interventions based on a patient's current vitals. Additional work must be done to have the network emulate the frequency at which drugs are selected from in clinical practice. In its current state, the model provides an understanding of how a PBN behaves in the context of correcting hemodynamic instability and can aid in developing more robust models in the future.

Assessment of physician compliance to the CAEP 2021 Atrial Fibrillation Best Practices Checklist for rate and rhythm control in the emergency department.

Acute atrial fibrillation and flutter (AF/AFL) are common arrhythmias treated in the emergency department (ED). The 2021 CAEP Best Practices Checklist provides clear recommendations for management of patients with acute AF/AFL. This study aimed to evaluate physician compliance to Checklist recommendations for risk assessment and ED management of AF/AFL. This health records review assessed the management of adult patients presenting to two tertiary care EDs for management of acute AF/AFL from January to August, 2022. All ECGs demonstrating AF/AFL with a heart rate greater than 100 were compiled to capture primary and secondary causes. All visits were assessed for rate and rhythm control management, adverse events, return to ED, and safety criteria. Study physicians classified safety criteria from the Checklist into high and moderate concerns. The primary outcome was the proportion of cases with safety concerns and adverse events occurring during management in the ED. Data were analyzed using simple descriptive statistics. We included 429 patients with a mean age of 67.7years and 57.1% male. ED management included rate control (20.4%), electrical (40.1%), and pharmacological (20.1%) cardioversion. Adverse events occurred in 9.5% of cases: 12.5% in rate control, 13.4% in electrical cardioversion, and 6.9% in pharmacologic cardioversion. Overall, 7.9% of cases had management safety concerns. Moderate safety concerns occurred in 4.9% of cases including failure to attain recommended heart rate at time of discharge (3.9%). Severe concerns were identified in 3.0% of cases including failure to cardiovert unstable patients (1.2%). The 30-day return-to-ED rate was 16.5% secondary to AF/AFL. ED management of AF/AFL was consistent with the CAEP Checklist and was safe overall. Opportunities for optimizing care include attaining recommended targets during rate control, avoidance of calcium channel and beta blockers in patients with systolic dysfunction, and earlier cardioversion for clinically unstable patients.

Autonomic Nerve Function Predicts Risk of Early Death after Discharge in Acute Medical Disease

BackgroundHeart rate variability, a marker of autonomic function, has shown promising prognostic results in specific populations, but has not been tested in a general medical population. We hypothesized that heart rate variability identifies high-risk medical patients early after admission to the hospital. MethodsThis was a single-center prospective cohort study of acutely admitted medical patients aged ≥18 years with a life expectancy ≥3 months, included between 2019-2023. Unstable patients needing direct admission to the intensive care unit were excluded. Heart rate variability was recorded within 24 hours of admission for 10 minutes. The standard deviation of normal-normal beats (SDNN) was the primary heart rate variability marker. Low SDNN was defined as the lowest tertile (≤22 ms). The primary outcome was 30-day all-cause mortality. The secondary outcome was 30-day readmission or mortality. ResultsAmong 721 patients included, low SDNN carried an 8-fold greater risk of 30-day mortality in univariate analysis (hazard ratio [HR] 8.3; P = .001); in multivariate analyses a 4-fold greater risk (HR 3.8; P = .037). Low SDNN was associated with the combined outcome of 30-day mortality or readmission (HR 1.5; P = .03) in multivariate analysis. In receiver operating characteristics analyses, low SDNN improved the predictive accuracy of early warning score for 30-day mortality or readmission from 0.63 to 0.71 (P = .008) but did not improve the accuracy for 30-day mortality alone. ConclusionsIn patients admitted due to acute medical illness, low heart rate variability predicted 30-day mortality and readmission, suggesting heart rate variability as a tool to identify patients at high and low risk of relevant endpoints.

Anticoagulation in the Management of Acute Pulmonary Embolism—A Review

AbstractVenous thromboembolism (VTE) is a very frequent cardiovascular entity that encompasses deep vein thrombosis and pulmonary embolism (PE). This last entity represents a major cause of cardiovascular morbidity and mortality. The incidence of PE and the rate of PE-related morbidity significantly increase with age, race, and underlying medical conditions, such as malignancy. Given the recent advances in diagnostic strategies and algorithms, patients can be risk assessed and treated promptly to avoid disease progression. Anticoagulation is the mainstay of treatment for acute PE that is not hemodynamically unstable. Direct oral anticoagulants, such as apixaban, rivaroxaban, or edoxaban, are currently the preferred agents for the treatment of patients who present with acute PE or for long-term treatment. Treatment duration should be continued for at least 3 months, and all patients should be assessed for extended duration of therapy based on the precipitating factors that led to the development of the VTE. Novel anticoagulant agents targeting factor XI/XIa are currently being investigated in phases 2 and 3 clinical trials, representing an attractive option in anticoagulation therapies in patients with VTE. For hemodynamically unstable patients, systemic thrombolysis is the treatment of choice, and it may also be of benefit—in reduced dose—for patients with intermediate to high risk who are at risk of hemodynamic collapse.

Time performance of scoop stretcher versus vacuum mattress for prehospital spinal stabilization: open-label simulation-based randomized controlled trial

Recent research has yielded conflicting results on the use of spinal stabilization in prehospital care, with some guidelines expressing concerns about its potential lack of benefit or harm. Transportation on a backboard can cause pain, discomfort, and pressure ulcers, whereas the log-roll technique can cause unnecessary movement and aggravate existing injuries. The scoop stretcher and vacuum mattress provide comparable or better immobilization and comfort than the backboard. Prehospital time is critical, and patients with life-threatening conditions should undergo rapid stabilization procedures. Despite this, some studies have overlooked the scoop stretcher as a spinal stabilization device. The primary goal was to compare the time required to achieve spinal stabilization using a scoop stretcher versus a vacuum mattress. This was a monocentric, parallel, randomized (sealed envelope), superiority, open-label, controlled simulation experiment. All student paramedics, registered paramedics, and EMTs who work in the participating EMS were eligible to participate in the study apart of the study team. The experimental group had to use a scoop stretcher, whereas the control group used a vacuum mattress. Fifteen participants were included. The scoop stretcher group required less time to complete the stabilization procedure (median [Q1; Q3]: 127 seconds [111;145] versus 212 [156;237], p=0.005). Using a scoop stretcher for spinal stabilization is more time-efficient than a vacuum mattress, making it a viable option for unstable trauma patients in the prehospital setting. More research is needed to determine its efficacy in actual clinical practice.

Can prolonged P-R interval predict clinical outcomes in non-ST elevation acute coronary syndrome patients?

BackgroundThe present study aimed to respond to clinical question, can prolonged P-R interval predict clinical outcomes in non-ST elevation acute coronary syndrome patients?MethodsThis descriptive-analytical study was conducted on cardiac patients. All of the non-ST elevation acute coronary syndrome (NSTEACS) including non-ST elevation myocardial infarction (NSTEMI) and unstable angina patients included in the study. Then they divided into two groups: prolonged P-R interval and normal P-R interval. The patients who had a history of digoxin and calcium channel blocker use, using antiarrhythmic drugs, known valvular or congenital heart disease and connective tissue, unreadable P-R interval and cardiac block were excluded. Data were collected using the questionnaire consisted demographic data and clinical outcomes and a follow-up part was completed by one of the researchers.ResultsFinally, 248 patients completed the study. The results showed both of the two groups had significant differences in terms of the history of myocardial infarction (MI) (p = 0.018), the level of high-density lipoprotein (HDL) (p = 0.004), heart rate (p = 0.042), inverted T wave (p = 0.017), anterior ST- segment depression (p = 0.008), normal report of coronary angiography (CAG) (p = 0.003), three vessels disease (p = 0.043), left main lesion (p = 0.045) and SYNTAX score (p = 0.032) based on the CAG report. The results of six-month follow-up showed although, the frequency of ischemic stroke, coronary artery disease (CAD) and cardiovascular death were higher in prolonged P-R interval groups. The chi-square test showed this difference was statistically non-significant (p > 0.05). The multivariate logistic regression model revealed non-significant relationships between prolonged P-R interval and SYNTAX score, significant CAD, three-vessel disease, inverted T wave, anterior ST depression, heart rate and HDL.ConclusionsBased on the results of our study the six-month follow-up showed non-significant outcomes. Further studies are recommended to assess the long-term outcomes.

A Clinical Review and Experience of Splenic Trauma in North India: A Retrospective Observational Study.

The spleen is one of the frequently injured solid organs in abdominal blunt trauma. The standard of care is nonoperative nowadays depending on the hemodynamic stability (World Society of Emergency Surgery (WSES) grade I-III) of the patient due to advancements in treating modalities. Operative interventions are required in hemodynamically unstable patients or failure of nonoperative management. The study was planned to find the clinical spectrum of abdominalblunt trauma, specifically those having splenic trauma, and their subsequent management in an institution. This is a retrospective observational study. All included patients with blunt abdominal injuries were treated in a level 1 trauma center between July 2021 and December 2022. Data regarding demographic profile, blood transfusion, pre- and postoperative findings, and management including the period of hospital stay, morbidity, and mortality were collected and analyzed. One hundred sixty-four patients were analyzed, of which 142 were males and 22 were females. The commonest mechanism of injury was motor vehicle collision, followed by falls. Grade III splenic injury was the most common injury, while the predominantly associated injury was rib fracture. The patients were managed preferably through nonoperative management, followed by angioembolization and operative management. The commonest postoperative complication was pneumonia. Nonoperative management of splenic trauma has evolved as the standard of care replacing operative management in order tosustain its immune function, thereby preventing overwhelming post-splenectomy infection.

Safety and efficacy of pelvic arterial embolization for primary postpartum hemorrhage in hemodynamically stable and hemodynamically unstable patients: Is it “time” for a paradigm change?

BackgroundPelvic artery embolization (PAE) is an effective and safe technique for treating postpartum hemorrhage (PPH) with hemodynamic stability. However, its use in hemodynamically unstable patients remains controversial. PurposeTo determine the safety and efficacy of pelvic arterial embolization (PAE) according to the hemodynamic state of primary postpartum hemorrhage (PPH) patients. MethodsThis cohort study was conducted retrospectively, using data from January 2004 to December 2021, in a resource-rich setting at a tertiary Level 1 trauma academic center. A total of 437 patients were diagnosed with PPH during the study period. Of these 437 patients, 161 with primary PPH who underwent PAE were enrolled in the study. The outcomes assessed included the clinical success rate, mortality, the overall success rate, predictive factors for failed PAE, and time-dependent changes in hemodynamic parameters, such as systolic blood pressure (SBP), heart rate (HR), and shock index (SI). Propensity score (PS) matching analysis was performed to assess the influence of specific variables or conditions on the outcomes. ResultsOf the 161 patients who underwent PAE for primary PPH (mean age, 32.9 ± 4.3 [SD]), 85 were retrospectively categorized as having hemodynamic stability (mean age, 32.6 ± 4.1 [SD]), while 76 were categorized as having hemodynamic instability (mean age, 33.3 ± 4.4 [SD]). This study showed PAE for primary PPH had a success rate of 91.9 %, with no significant difference in mortality rates between the groups. The clinical success rate was 98.8 % for patients with hemodynamic stability and 84.2 % for those with hemodynamic instability (p < .001). The overall success rate was 98.8 % for hemodynamic stability and 89.5 % for hemodynamic instability (p = .014). After propensity score matching, the clinical success rate was higher in hemodynamically stable patients than in unstable ones (100 % vs. 86.3 %, p = .013). However, there was no significant difference in the overall success rate (100 % vs. 90.2 %, p = .056). Among the PS-matched population, predictive factors for the failed PAE in primary PPH were hemodynamic instability (adjusted odds ratio [aOR] 21.22, 95 % CI 1.27-355.76; p = .034) and emergency Cesarean delivery with accompanying hemorrhag (aOR 54.00, 95 % CI 11.93-244.56; p = .008). In three groups within a PS-matched population — hemodynamically stable, unstable with successful outcomes, and unstable with unsuccessful outcomes, a generalized linear mixed model (GLMM) analysis for time-dependent changes in hemodynamic parameters revealed a statistically significant difference in SBP, HR, and SI at various time points. ConclusionPelvic arterial embolization of primary postpartum bleeding in hemodynamic instability has been identified as an alternative, safe, and effective life-saving procedure for multidisciplinary treatment in resource-rich environments even after the baseline characteristics are balanced by the PS matching, suggesting it is a primary care option.
