RESUMEN
INTRODUCTION: The membranous septum (MS) length measured by cardiac computed tomography (CT) is useful for the prediction of permanent pacemaker implantation (PPMI) and new left bundle branch block (LBBB) after transcatheter aortic valve replacement. However, its predictive value for patients undergoing surgical aortic valve replacement (SAVR) is unknown. METHODS: A total of 2531 consecutive patients were registered in the institutional Society of Thoracic Surgeons database between July 2017 and June 2020. Patients who underwent non-SAVR procedures, had prior pacemaker/implantable cardioverter defibrillator, prior SAVR, no preprocedural CT assessment, or suboptimal CT imaging were excluded. RESULTS: A total of 126 SAVR with preprocedural CT assessment were analyzed. Bicuspid aortic valve morphology was confirmed on CT in 59.5% of patients. There were three new PPMIs and five new LBBBs observed after SAVR at the time of discharge. In-hospital mortality was 0.8%. Low left ventricular (LV) ejection fraction (<50%), LV mass index >120 g/m2, large right coronary artery height, and MS length <1.5 mm predicted new PPMI/LBBB. Multivariate analysis showed LV mass index >120 g/m2 (odds ratio: 9.165; 95% confidence interval: 1.644-51.080; P = 0.011) and MS length <1.5 mm (odds ratio: 14.449; 95% confidence interval: 1.632-127.954; P = 0.016) were independent predictors for new PPMI/LBBB. CONCLUSIONS: Short MS length on preoperative cardiac CT is a powerful and novel predictor for the risk of new PPMI/LBBB after SAVR. Special care should be taken in patients with short MS length to avoid suture-mediated trauma.

BACKGROUND: Patients with renal insufficiency have poor short-term outcomes after transcatheter aortic valve replacement (TAVR). METHODS: Retrospective chart review identified 575 consecutive patients not on hemodialysis who underwent TAVR between September 2014 and January 2017. Outcomes were defined by VARC-2 criteria. Primary outcome of all-cause mortality was evaluated at a median follow-up of 811 days (interquartile range 125-1,151). RESULTS: Preprocedural glomerular filtration rate (GFR) was ≥60 ml/min in 51.7%, 30-60 ml/min in 42.1%, and < 30 ml/min in 6.3%. Use of transfemoral access (98.8%) and achieved device success (91.0%) did not differ among groups, but less contrast was used with lower GFR (23 ml [15-33], 24 ml [14-33], 13 ml [8-20]; p < .001). Peri-procedural stroke (0.7%, 2.1%, 11.1%; p < .001) was higher with lower GFR. Core lab analysis of preprocedural computed tomography scans of patients who developed a peri-procedural stroke identified potential anatomic substrate for stroke in three out of four patients with GFR 30-60 ml/min and all three with GFR <30 ml/min (severe atheroma was the most common subtype of anatomical substrate present). Compared to GFR ≥60 ml/min, all-cause mortality was higher with GFR 30-60 ml/min (HR 1.61 [1.00-2.59]; aHR 1.61 [0.91-2.83]) and GFR <30 ml/min (HR 2.41 [1.06-5.48]; aHR 2.34 [0.90-6.09]) but not significant after multivariable adjustment. Follow-up echocardiographic data, available in 63%, demonstrated no difference in structural heart valve deterioration over time among groups. CONCLUSIONS: Patients with baseline renal insufficiency remain a challenging population with poor long-term outcomes despite procedural optimization with a transfemoral-first and an extremely low-contrast approach.

PURPOSE: This study aimed to compare analgesic efficacy of intranasal (IN) ketamine to IN fentanyl for moderate to severe pain in children in a pediatric emergency department. METHODS: A prospective, randomized, double-blinded, noninferiority study evaluating children aged 3 to 17 years in a pediatric emergency department with acute moderate to severe pain was conducted. Patients received either 1 mg/kg of IN ketamine or 1.5 µg/kg of IN fentanyl and were evaluated after 10, 20, 30, and 60 minutes. The primary outcome was the degree of pain reduction after 20 minutes. RESULTS: Twenty-two patients were enrolled (11 in each group). Underlying pain conditions represented were musculoskeletal injury (73%) and abdominal pain (27%). At 20 minutes after analgesia, there was no significant difference in pain scores between the fentanyl (median, 2; range, 0-8) and ketamine groups (median, 4; range, 0-7; P = 0.20). The ketamine group showed a significantly greater rate of adverse effects, 73% versus 9% (P = 0.002), and throughout the course of the study period, 7 patients in the ketamine group (64%) group showed some degree of sedation versus no one in the fentanyl group (P = 0.004). CONCLUSIONS: There was insufficient power to support the analgesic noninferiority of IN ketamine at a dose of 1 mg/kg compared with IN fentanyl at a dose of 1.5 µg/kg in children experiencing painful conditions at 20 minutes after administration. Intranasal ketamine was found to be inferior to IN fentanyl in relieving pain at 10 minutes and was found to have significantly greater rates of sedation and dizziness.

OBJECTIVE: Emergency Department patients with abdominal pain may require both an ultrasound (US) and computed tomography (CT) for an accurate diagnosis. Patients are often asked to drink oral radiocontrast while awaiting ultrasound, in order to better expedite a CT in the case of a non-diagnostic US. The impact of oral radiocontrast on US image quality has not been studied. We compared the quality of US images obtained before and after the ingestion of oral radiocontrast in healthy adult volunteers. METHODS: This was a prospective study in which adult volunteer subjects underwent sonographic studies of the aorta, the right upper quadrant, the right lower quadrant, and the Focused Assessment with Sonography in Trauma (FAST) examination. Initial studies were performed prior to ingestion of oral radiocontrast, with subsequent imaging occurring at 1 and 2hour post-ingestion. All of the images from the sonographic exams were randomized and subsequently scored for quality by two emergency ultrasound fellowship trained emergency physicians with extensive experience in performing and interpreting US. RESULTS: 638 images from 240 exams were obtained from 20 subjects at three time points. Six exams were not scored due to inadequate images. There were no significant differences in image quality for any of the US exam types after the ingestion of oral radiocontrast at 1 and 2h. CONCLUSION: Ingestion of oral radiocontrast did not affect image quality of four common abdominal ultrasound examinations.

STUDY OBJECTIVE: Nonsteroidal anti-inflammatory drugs are used extensively for the management of acute and chronic pain, with ketorolac tromethamine being one of the most frequently used parenteral analgesics in the emergency department (ED). The drugs may commonly be used at doses above their analgesic ceiling, offering no incremental analgesic advantage while potentially adding risk of harm. We evaluate the analgesic efficacy of 3 doses of intravenous ketorolac in ED patients with acute pain. METHODS: We conducted a randomized, double-blind trial to assess the analgesic efficacy of 3 doses of intravenous ketorolac (10, 15, and 30 mg) in patients aged 18 to 65 years and presenting to the ED with moderate to severe acute pain, defined by a numeric rating scale score greater than or equal to 5. We excluded patients with peptic ulcer disease, gastrointestinal hemorrhage, renal or hepatic insufficiency, allergies to nonsteroidal anti-inflammatory drugs, pregnancy or breastfeeding, systolic blood pressure less than 90 or greater than 180 mm Hg, and pulse rate less than 50 or greater than 150 beats/min. Primary outcome was pain reduction at 30 minutes. We recorded pain scores at baseline and up to 120 minutes. Intravenous morphine 0.1 mg/kg was administered as a rescue analgesic if subjects still desired additional pain medication at 30 minutes after the study drug was administered. Data analyses included mixed-model regression and ANOVA. RESULTS: We enrolled 240 subjects (80 in each dose group). At 30 minutes, substantial pain reduction was demonstrated without any differences between the groups (95% confidence intervals 4.5 to 5.7 for the 10-mg group, 4.5 to 5.6 for the 15-mg group, and 4.2 to 5.4 for the 30-mg group). The mean numeric rating scale pain scores at baseline were 7.7, 7.5, and 7.8 and improved to 5.1, 5.0, and 4.8, respectively, at 30 minutes. Rates of rescue analgesia were similar, and there were no serious adverse events. Secondary outcomes showed similar rates of adverse effects per group, of which the most common were dizziness, nausea, and headache. CONCLUSION: Ketorolac has similar analgesic efficacy at intravenous doses of 10, 15, and 30 mg, showing that intravenous ketorolac administered at the analgesic ceiling dose (10 mg) provided effective pain relief to ED patients with moderate to severe pain without increased adverse effects.

This is a case of a 19-year-old male who presented to the medical tent at an outdoor electronic dance music festival (EDMF) due to an altered mental state in the setting of acute 3,4-methylenedioxymethamphetamine (MDMA) intoxication. He was noted to be in severe respiratory distress, required endotracheal intubation in the field and subsequently developed Acute Respiratory Distress Syndrome (ARDS) without other acute organ dysfunction. He was hospitalized for 5days requiring endotracheal intubation and mechanical ventilation. By presenting this case, we will explore and discuss the cardiopulmonary effects of MDMA intoxication that can lead to a rare, deleterious complication of MDMA intoxication other than previously reported adverse outcomes.

STUDY OBJECTIVE: Compare adverse effects and analgesic efficacy of low-dose ketamine for acute pain in the ED administered either by single intravenous push (IVP) or short infusion (SI). METHODS: Patients 18-65, presenting to ED with acute abdominal, flank, or musculoskeletal pain with initial pain score≥5, were randomized to ketamine 0.3mg/kg by either IVP or SI with placebo double-dummy. Adverse effects were evaluated by Side Effects Rating Scale for Dissociative Anesthetics (SERSDA) and Richmond Agitation-Sedation Scale (RASS) at 5, 15, 30, 60, 90, and 120min post-administration; analgesic efficacy was evaluated by Numerical Rating Scale (NRS). RESULTS: 48 patients enrolled in the study. IVP group had higher overall rates of feeling of unreality on SERSDA scale: 92% versus 54% (difference 37.5%; p=0.008; 95% CI 9.3-59.5%). At 5min median severity of feeling of unreality was 3.0 for IVP versus 0.0 for SI (p=0.001). IVP also showed greater rates of sedation on RASS scale at 5min: median RASS -2.0 versus 0.0 (p=0.01). Decrease in mean pain scores from baseline to 15min was similar across groups: 5.2±3.53 (95% CI 3.7-6.7) for IVP; 5.75±3.48 (95% CI 4.3-7.2) for SI. There were no statistically significant differences with respect to changes in vital signs and need for rescue medication. CONCLUSION: Low-dose ketamine given as a short infusion is associated with significantly lower rates of feeling of unreality and sedation with no difference in analgesic efficacy in comparison to intravenous push.

OBJECTIVES: To compare pain relief between patients with intracapsular and extracapsular hip fractures who received an ultrasound-guided femoral nerve block (USFNB). DESIGN: A multicenter, prospective, randomized, clinical trial. SETTING: The study was conducted in the emergency departments of 3 academic hospitals located in New York City. SUBJECTS: Patients aged ≥60 years presenting to the emergency department with hip fracture. METHODS: A subgroup analysis from a larger data set was conducted of patients with intracapsular and extracapsular hip fractures who received an USFNB. We compared pain scores at baseline and then at 2 and 3 hours after the nerve block was performed, and also assessed pain relief at 2 and 3 hours. RESULTS: Seventy-seven patients were randomized to receive USFNB, of which 68 had follow-up data at 2 and 3 hours and were included in the data analysis. Thirty-one were diagnosed with intracapsular and 37 with extracapsular hip fractures. In both groups, reductions in pain scores were clinically and statistically significant. In the intracapsular group, mean pain scores decreased from 6.23 to 3.81 (P < .0001) at 2 hours and from 6.23 to 3.87 (P < .0001) at 3 hours. In the extracapsular group, mean pain scores decreased from 6.62 to 3.89 (P < .0001) at 2 hours and from 6.62 to 3.46 (P < .0001) at 3 hours. These differences were similar between the extracapsular and intracapsular groups at 2 hours (P = .92) and at 3 hours (P = .58), thus demonstrating similar reductions in pain in the 2 groups. The differences in pain relief between the intracapsular and extracapsular groups were also similar: 1.61 (confidence interval [CI], 1.14-2.08) vs 1.35 (CI, 0.96-1.75) at 2 hours (P = .39) and 1.68 (CI, 1.21-2.15) vs 1.38 (CI, 0.89-1.87) at 3 hours (P = .38). CONCLUSION: Ultrasound-guided femoral nerve block was equally effective in reducing pain for patients with both intracapsular and extracapsular hip fractures.

STUDY OBJECTIVE: We assess and compare the analgesic efficacy and safety of subdissociative intravenous-dose ketamine with morphine in emergency department (ED) patients. METHODS: This was a prospective, randomized, double-blind trial evaluating ED patients aged 18 to 55 years and experiencing moderate to severe acute abdominal, flank, or musculoskeletal pain, defined as a numeric rating scale score greater than or equal to 5. Patients were randomized to receive ketamine at 0.3 mg/kg or morphine at 0.1 mg/kg by intravenous push during 3 to 5 minutes. Evaluations occurred at 15, 30, 60, 90, and 120 minutes. Primary outcome was reduction in pain at 30 minutes. Secondary outcome was the incidence of rescue analgesia at 30 and 60 minutes. RESULTS: Forty-five patients per group were enrolled in the study. The primary change in mean pain scores was not significantly different in the ketamine and morphine groups: 8.6 versus 8.5 at baseline (mean difference 0.1; 95% confidence interval -0.46 to 0.77) and 4.1 versus 3.9 at 30 minutes (mean difference 0.2; 95% confidence interval -1.19 to 1.46; P=.97). There was no difference in the incidence of rescue fentanyl analgesia at 30 or 60 minutes. No statistically significant or clinically concerning changes in vital signs were observed. No serious adverse events occurred in either group. Patients in the ketamine group reported increased minor adverse effects at 15 minutes post-drug administration. CONCLUSION: Subdissociative intravenous ketamine administered at 0.3 mg/kg provides analgesic effectiveness and apparent safety comparable to that of intravenous morphine for short-term treatment of acute pain in the ED.

OBJECTIVES: The aim of this study was to clarify the dynamics of the mitral annulus throughout the cardiac cycle and its relevance to transcatheter mitral valve replacement (TMVR) sizing and case selection. BACKGROUND: Limited data are available regarding the relevance of mitral annular (MA) and neo-left ventricular outflow tract (LVOT) dynamics in the overall population presenting with significant mitral valve disease. METHODS: Patients attending a combined surgical-transcatheter heart valve clinic for severe symptomatic mitral valve disease were assessed using multiphase computed tomography. The relative influence of MA and neo-LVOT dynamics to TMVR case selection was studied. RESULTS: A total of 476 patients with significant mitral valve disease were evaluated. In 99 consecutive patients with severe mitral regurgitation, a 10-phase assessment showed that the mitral annulus was on average largest in late systole. On comparing maximal MA dimension with late systolic dimension, TMVR size assignment changed in 24.2% of patients. If the average MA perimeter was used to determine sizing, 48.5% were excluded because of MA dimension being too large; in a multiphase assessment of the neo-LVOT, an additional 16.2% were excluded on the basis of neo-LVOT dimension. In an expanded series of 312 consecutive patients, selection protocol influenced anatomical exclusion: a manufacturer-proposed early systolic approach excluded 69.2% of patients, whereas a late systolic approach excluded 82.7% of patients, the vast majority because of large mitral annuli. CONCLUSIONS: Contemporary TMVR can treat only a minority of patients with severe mitral regurgitation, principally because of limitations of large MA dimension.

BACKGROUND: Communication and interpersonal skills are important for effective patient care but are difficult to measure. Unannounced standardized patient encounters (USPEs) have the benefit of providing a standardized situation and provide a representation of usual care rather than best behavior, while also allowing for video recording without violating patient privacy. We conducted a feasibility pilot study to examine the use of videotaped USPEs in resident education of interpersonal and communication skills and specifically empathy. METHODS: This was a pilot study conducted at an urban community teaching hospital. About 16 first-year emergency medicine engaged in four videotaped USPEs during their normal clinical shifts during 1 academic year. All visible recording equipment was concealed from the residents. The standardized patients completed two assessment forms after each encounter to measure empathy. RESULTS: All 16 residents engaged in four videotaped USPEs for a total of 64 encounters. CONCLUSIONS: We were able to successfully demonstrate the feasibility of using USPEs for assessment of resident interpersonal and communication skills.
RESUMEN
INTRODUCTION: It is commonly assumed that orally-administered radiocontrast material (ORC) preceding abdominal ultrasound (US) performance can obscure image quality and potentially impair diagnostic accuracy when assessing patients with abdominal pain. Due to this concern, ORC administration per protocol for computed tomography (CT) is often delayed until after US performance, potentially contributing to prolonged length of stay in the emergency department (ED) in patients with concern for abdominal pathology. The objective of this study was to evaluate whether early administration of ORC in children with abdominal pain receiving abdominal CT for possible appendicitis obscures subsequent abdominal US image quality. METHODS: We designed a prospective observational study of children <18 years of age presenting to a pediatric ED with abdominal pain who were set to receive ORC prior to obtaining an abdominal CT. These patients received a point-of-care ultrasound (POCUS) of the abdomen to assess the abdominal aorta and right lower quadrant (RLQ) structures (psoas muscle and iliac vessels) pre- and post-ORC administration. Images were compared independently by two blinded emergency US-certified physician-assessors for quality, specifically to determine whether ORC obscured the anatomical structures in question. RESULTS: A total of 17 subjects were enrolled, and each subject had two POCUS studies of the abdomen, one pre- and one post-ORC administration looking to visualize the anatomy of the RLQ and abdominal aorta in both studies. Statistical analysis showed no significant differences in mean values of POCUS image quality scoring by two blinded US-trained physician-assessors for either RLQ structures or abdominal aorta when performed pre- and post-administration of ORC. CONCLUSION: Early ORC administration in children with abdominal pain does not adversely affect image quality of a subsequently performed abdominal US. Patients who may require abdominal CT to determine the etiology of abdominal pain can receive early administration of ORC prior to US performance to help minimize ED length of stay without impairing US diagnostic accuracy.

INTRODUCTION: Family presence during emergency resuscitations is increasingly common, but the question remains whether the practice results in psychological harm to the witness. We examine whether family members who witness resuscitations have increased post-traumatic stress disorder (PTSD) symptoms at one month following the event. METHODS: We identified family members of critically ill patients via our emergency department (ED) electronic health record. Patients were selected based on their geographic triage to an ED critical care room. Family members were called a median of one month post-event and administered the Impact of Event Scale-Revised (IES-R), a 22-item validated scale that measures post-traumatic distress symptoms and correlates closely with Diagnostic and Statistical Manual of Mental Disorders-IV criteria for post-traumatic stress disorder (PTSD). Family members were placed into two groups based on whether they stated they had witnessed the resuscitation (FWR group) or not witnessed the resuscitation (FNWR group). Data analyses included chi-square test, independent sample t-test, and linear regression controlling for gender and age. RESULTS: A convenience sample of 423 family members responded to the phone interview: 250 FWR and 173 FNWR. The FWR group had significantly higher mean total IES-R scores: 30.4 vs 25.6 (95% confidence interval [CI], -8.73 to -0.75; P<.05). Additionally, the FWR group had significantly higher mean score for the subscales of avoidance (10.6 vs 8.1; 95% CI, -4.25 to -0.94; P<.005) and a trend toward higher score for the subscale of intrusion (13.0 vs 11.4; 95% CI, -3.38 to .028; P = .054). No statistical significant difference was noted between the groups in the subscale of hyperarousal (6.95 vs 6.02; 95% CI, -2.08 to 0.22; P=.121). All findings were consistent after controlling for age, gender, and immediate family member (spouse, parent, children, and grandchildren). CONCLUSION: Our results suggest that family members who witness ED resuscitations may be at increased risk of PTSD symptoms at one month. This is the first study that examines the effects of family visitation for an unsorted population of very sick patients who would typically be seen in the critical care section of a busy ED.

OBJECTIVES: This study sought to minimize the risk of permanent pacemaker implantation (PPMI) with contemporary repositionable self-expanding transcatheter aortic valve replacement (TAVR). BACKGROUND: Self-expanding TAVR traditionally carries a high risk of PPMI. Limited data exist on the use of the repositionable devices to minimize this risk. METHODS: At NYU Langone Health, 248 consecutive patients with severe aortic stenosis underwent TAVR under conscious sedation with repositionable self-expanding TAVR with a standard approach to device implantation. A detailed analysis of multiple factors contributing to PPMI was performed; this was used to generate an anatomically guided MInimizing Depth According to the membranous Septum (MIDAS) approach to device implantation, aiming for pre-release depth in relation to the noncoronary cusp of less than the length of the membranous septum (MS). RESULTS: Right bundle branch block, MS length, largest device size (Evolut 34 XL; Medtronic, Minneapolis, Minnesota), and implant depth > MS length predicted PPMI. On multivariate analysis, only implant depth > MS length (odds ratio: 8.04; 95% confidence interval: 2.58 to 25.04; p < 0.001) and Evolut 34 XL (odds ratio: 4.96; 95% confidence interval: 1.68 to 14.63; p = 0.004) were independent predictors of PPMI. The MIDAS approach was applied prospectively to a consecutive series of 100 patients, with operators aiming to position the device at a depth of < MS length whenever possible; this reduced the new PPMI rate from 9.7% (24 of 248) in the standard cohort to 3.0% (p = 0.035), and the rate of new left bundle branch block from 25.8% to 9% (p < 0.001). CONCLUSIONS: Using a patient-specific MIDAS approach to device implantation, repositionable self-expanding TAVR achieved very low and predictable rates of PPMI which are significantly lower than previously reported with self-expanding TAVR.

BACKGROUND: Ketorolac tromethamine is a non-steroidal anti-inflammatory drug (NSAIDs) that is widely used in the emergency department (ED) for the treatment of moderate-to-severe pain. Ketorolac, like other NSAIDs, exhibits an analgesic ceiling effect and previous research suggests that 10 mg is possibly the ceiling dose. Do the patterns of ketorolac dosing by emergency physicians follow its analgesic ceiling dose? METHODS: This was a single center retrospective, descriptive study to characterize patterns of ketorolac administration in ED patients. Data for all patients who received ketorolac during the ten year study period from January 1, 2003 to January 1, 2013 were collected from the electronic medical record of an urban community ED with an annual volume of 116 935 patients. RESULTS: There were 49 605 ketorolac administrations during the study period; 38 687 (78%) were given intravenously, 9 916 (20%) intramuscularly, and 1 002 (2%) orally. Through the intravenous route, 5 288 (13.7%) were 15 mg, 32 715 (84.6%) were 30 mg, 15 (0.03%) were 60 mg, and 669 (1.7%) were other varying doses. Through the intramuscular route, 102 (1.0%) were 15 mg, 4 916 (49.6%) were 30 mg, 4 553 (45.9%) were 60 mg, and 345 (3.5%) were other varying doses. The most common diagnoses at discharge were renal colic (21%), low back pain (17%) and abdominal pain (11%). CONCLUSION: The data show that ketorolac was prescribed above its ceiling dose of 10 mg in 97% of patients who received intravenous doses and in 96% of patients receiving intramuscular doses.
RESUMEN
Mass-Gathering Medicine studies have identified variables that predict greater patient presentation rates (PPRs) and transport to hospital rates (TTHRs). This is a descriptive report of patients who presented for medical attention at an annual electronic dance music festival (EDMF). At this large, single EDMF in New York City (NYC; New York, USA), the frequency of patient presentation, the range of presentations, and interventions performed were identified. This descriptive report examined consecutive patients who presented to the medical tent of a summertime EDMF held at an outdoor venue with an active, mobile, bounded crowd. Alcohol was available for sale. Entry was restricted to persons 18 years and older. The festival occurred on three consecutive days with a total cumulative attendance of 58,000. Medical staffing included two Emergency Medicine physicians, four registered nurses, and 86 Emergency Medical Services (EMS) providers. Data collected included demographics, past medical history, vital signs, physical exam, drug and alcohol use, interventions performed, and transport decisions. Eighty-four patients were enrolled over 2.5 days. Six were transported and zero died. The ages of the subjects ranged from 17 to 61 years. Forty-three (51%) were male. Thirty-eight (45%) initially presented with abnormal vital signs; four (5%) were hyperthermic. Of these latter patients, 34 (90%) reported ingestions with 3,4-methylenedioxymethamphetamine (MDMA) or other drugs. Eleven (65%) patients were diaphoretic or mydriatic. The most common prehospital interventions were intravenous normal saline (8/84; 10%), ondansetron (6/84; 7%), and midazolam (3/84; 4%). Electronic dance music festivals are a growing trend and a new challenge for Mass-Gathering Medicine as new strategies must be employed to decrease TTHR and mortality. Addressing common and expected medical emergencies at mass-gathering events through awareness, preparation, and early, focused medical interventions may decrease PPR, TTHR, and overall mortality.
