Image-Guided Resuscitation With Limited Transthoracic Echocardiogram in Pediatric Trauma Patients.

INTRODUCTION: Limited transthoracic echocardiogram (LTTE) has been shown to be a useful tool in guiding resuscitation in adult trauma patients. Our hypothesis is that image-guided resuscitation in pediatric trauma patients with LTTE is feasible. METHODS: A retrospective chart review was performed on highest level pediatric trauma alerts (age 18 years or younger) at our level I trauma center during a 6-month period. Patients were divided into 2 groups as follows: those who had LTTE performed (LTTE group) and those who did not have LTTE performed (non-LTTE group). RESULTS: A total of 31 charts were reviewed; 4 patients were excluded because they died on arrival to the emergency department. Fourteen patients had LTTE performed (LTTE group); 13 patients did not have LTTE performed (non-LTTE group). There was no difference in mechanism of injury, age, injury severity score, weight, or intensive care unit admission between the groups. The LTTE group received significantly less intravenous fluid than the non-LTTE group (1.2 vs 2.3 L, P = 0.0013).Within the LTTE group, 8 patients had "full" inferior vena cava (IVC) and 6 patients had "empty" IVC. There was no difference in injury severity score between these subgroups (P = 0.1018). Less fluid was given in the group labeled with full IVC [1.1 L (0.8-1.2)] than the group with empty IVC [2.4 L (1.7-2.6)], P = 0.0005. Four of the 6 patients with "empty" IVC had a confirmed source of bleeding. CONCLUSIONS: Limited transthoracic echocardiogram can limit the amount of unnecessary crystalloid resuscitation given to pediatric trauma patients who are not hypovolemic.

Use of limited transthoracic echocardiography in patients with traumatic cardiac arrest decreases the rate of nontherapeutic thoracotomy and hospital costs.

OBJECTIVES: Limited transthoracic echocardiography (LTTE) has been introduced as a hemodynamic tool for trauma patients. The aim of this study was to evaluate the utility of LTTE during the evaluation of nonsurviving patients who presented to the trauma bay with traumatic cardiac arrest. METHODS: Approval by the Institutional Review Board was obtained. All nonsurviving patients with traumatic cardiac arrest who reached the trauma bay were evaluated retrospectively for 1 year. Comparisons between groups of patients in whom LTTE was performed as part of the resuscitation effort and those in whom it was not performed were conducted. RESULTS: From January 2012 to January 2013, 37 patients did not survive traumatic cardiac arrest while in the trauma bay: 14 in the LTTE group and 23 in the non-LTTE group. When comparing the LTTE and non-LTTE groups, both were similar in sex distribution (LTTE, 86% male; non-LTTE, 74% male; P = .68), age (34.8 versus 24.1 years; P= .55), Injury Severity Score (41.0 versus 38.2; P= .48), and percentage of penetrating trauma (21.6% versus 21.7%; P = .29). Compared with the non-LTTE group, the LTTE group spent significantly less time in the trauma bay (13.7 versus 37.9 minutes; P = .01), received fewer blood products (7.1% versus 31.2%; P = .789), and were less likely to undergo nontherapeutic thoracotomy in the emergency department (7.14% versus 39.1%; P < .05). The non-LTTE group had a mean of $3040.50 in hospital costs, compared with the mean for the LTTE group of $1871.60 (P = .0054). CONCLUSIONS: In this study, image-guided resuscitation with LTTE decreased the time in the trauma bay and avoided nontherapeutic thoracotomy in nonsurviving trauma patients. Limited TTE could improve the use of health care resources in patients with traumatic cardiac arrest.

Older patients' aversion to antidepressants. A qualitative study.

BACKGROUND: Depression is common among older patients yet is often inadequately treated. Patient beliefs about antidepressants are known to affect treatment initiation and adherence, but are often not expressed in clinical settings. OBJECTIVE: To explore attitudes toward antidepressants in a sample of depressed, community-dwelling elders who were offered treatment. DESIGN. Cross-sectional, qualitative study utilizing semi-structured interviews. PARTICIPANTS: Primary care patients age 60 years and over with depression, from academic and community primary care practices of the University of Pennsylvania Health System and the Philadelphia Department of Veterans Affairs. Patients participated in either the Prevention of Suicide in Primary Care Elderly: Collaborative Trial or the Primary Care Research in Substance Abuse and Mental Health for the Elderly Trial. Sixty-eight patients were interviewed and responses from 42 participants with negative attitudes toward medication for depression were analyzed. MEASUREMENTS: Interviews were audiotaped, transcribed, and entered into a qualitative software program for coding and analysis. A multidisciplinary team of investigators coded the transcripts and identified key features of narratives expressing aversion to antidepressants. RESULTS: Four themes characterized resistance to antidepressants: (1) fear of dependence; (2) resistance to viewing depressive symptoms as a medical illness; (3) concern that antidepressants will prevent natural sadness; (4) prior negative experiences with medications for depression. CONCLUSIONS: Many elders resisted the use of antidepressants. Patients expressed concerns that seem to reflect their concept of depression as well as their specific concerns regarding antidepressants. These findings may enhance patient-provider communication about depression treatment in elders.

Defining the cervical spine clearance algorithm: A single-institution prospective study of more than 9,000 patients.

BACKGROUND: Variability exists in the approach to cervical spine (c-spine) clearance after significant trauma. Using concurrently gathered data on more than 9,000 such patients, the current study develops an evidence-based and readily adoptable algorithm for c-spine clearance aimed at timely removal of collar, optimal use of imaging, and appropriate spine consultations. METHODS: Prospective study of adult blunt trauma team alert (TTA) patients presenting at a Level I trauma center who underwent screening computed tomography (CT) to diagnose/rule out c-spine injury (January 2008 to May 2014). Regression analysis comparing patients with and without c-spine injury-fracture and/or ligament-was used to identify significant predictors of injury. The predictors with the highest odds ratio were used to develop the algorithm. RESULTS: Among 9,227 patients meeting inclusion criteria, c-spine injury was identified in 553 patients (5.99%). All 553 patients had a c-spine fracture, and of these, 57 patients (0.6% of entire population and 10.31% of patients with injury) also had a ligamentous injury. No patient with a normal CT result was found to have an injury. The five greatest predictors of ligament injury that follow were used to develop the algorithm: (1) CT evidence of ligament injury; (2) fracture pattern "not" isolated transverse/spinous process; (3) neurologic symptoms; (4) midline tenderness; and (5) Glasgow Coma Scale score <15. CONCLUSION: TTA patients should undergo screening c-spine CT to rule out injury. Most patients will have a negative CT and can have their collars removed. A select group of patients will require collars and spine consultation and a smaller subset of magnetic resonance imaging to rule out ligament injury. LEVEL OF EVEDINCE: Therapeutic study, level III.

Pediatric health care provider perceptions of weight loss surgery in adolescents.

This study explored pediatric health care providers' obesity treatment practices and perceptions about adolescent weight loss surgery (WLS). Surveys were e-mailed to pediatric listservs. After descriptive analyses, correlations, chi-squares, and one-way analyses of variance compared responses by provider characteristics. Surveys were completed by 109 providers. Almost half do not routinely measure body mass index. Providers typically counsel patients about lifestyle change, with limited perceived benefit; <10% have ever referred patients for WLS, citing cost (20%), risk (49%), or "not indicated in pediatrics" (17%) as reasons. However, when presented with patient scenarios of different ages and comorbidities, likeliness to refer for WLS increased substantially. Surgeons, younger providers and those with fewer years of experience were more likely to refer for WLS (P < .05). Despite expert consensus recommendations supporting WLS as part of a comprehensive obesity treatment plan, significant pediatric provider resistance to refer obese adolescents remains. Improved referral and management practices are needed.

Laparoscopic gastric plication in the morbidly obese adolescent patient.

Childhood obesity is a significant problem. Due in part to suboptimal weight loss with lifestyle intervention alone, bariatric surgery, combined with ongoing lifestyle changes, has become a favorable approach in adolescents with severe obesity and weight-related comorbidities and is associated with effective weight loss and reducing weight-related comorbidities. Laparoscopic greater curvature plication is a promising new bariatric surgical procedure that has been shown to be effective in adults with severe obesity but has not been evaluated in the adolescent population. Gastric plication may be a particularly attractive approach for the adolescent patient as it is potentially reversible, does not involve the surgical removal of tissue, and is without a significant malabsorptive component. Our team has obtained approval from our Institutional Review Board to perform a laparoscopic greater curvature plication on 30 adolescent patients with severe obesity and study its effect on weight loss, metabolic effects, and psychological functioning in the setting of a multidisciplinary program. Results of this study, including comprehensive clinical and psychological data collected over a 3.5-year span, will inform larger prospective investigations comparing the laparoscopic greater curvature plication and other bariatric operations in the adolescent population.

Computed tomographic scan: it's not just about the fracture.

BACKGROUND: Computed tomography (CT) scan is the criterion standard to rule out cervical spine (c-spine) injury after blunt trauma. Many algorithms still include other tools to exclude ligamentous injuries that often lead to unnecessary prolonged collar use. The purpose of this study was to determine the accuracy of CT to rule out any clinically significant c-spine injury that would require intervention. METHODS: We performed a retrospective review of a prospective study of blunt trauma patients between January 2008 and December 2012 at a Level 1 trauma center. For those patients identified with ligamentous injury, further chart review was performed to determine how it was diagnosed and treated. RESULTS: A total of 5,676 patients were identified. The median age was 39.0 years (18-103 years), median Glasgow Coma Scale (GCS) score was 15 (3-15), median Injury Severity Score (ISS) was 5 (1-75), median length of stay was 2 days (1-175 days), and mortality was 2.6%. The incidence of any injury to the c-spine was 7.4% (420 of 5,676). The incidence of fracture was 7.2% (409 of 5,676), while that of ligamentous injury was 0.92% (52 of 5,676). Of the 52 patients with ligamentous injury, 20 (38.4%) were suspected by CT. However, for those that were not suspected, all had associated fractures identified by CT, requiring further interventions. Hence, CT had a 100% sensitivity and specificity in ruling out c-spine injuries. CONCLUSION: CT scan of the c-spine is an excellent tool to rule out c-spine injury. For patients with a normal CT finding of the c-spine, no further imaging is necessary, and collars should be cleared as soon as possible. LEVEL OF EVIDENCE: Prognostic study, level II; diagnostic study, level II.

Findings of a randomized controlled trial using limited transthoracic echocardiogram (LTTE) as a hemodynamic monitoring tool in the trauma bay.

BACKGROUND: We hypothesize that limited transthoracic echocardiogram (LTTE) is a useful tool to guide therapy during the initial phase of resuscitation in trauma patients. METHODS: All highest-level alert patients with at least one measurement of systolic blood pressure less than 100 mm Hg, a mean arterial pressure less than 60 mm Hg, and/or a heart rate greater than 120 beats per minute who arrived to the trauma bay (TB) were randomized to have either LTTE performed (LTTEp) or not performed (non-LTTE) as part of their initial evaluation. Images were stored, and results were reported regarding contractility (good vs. poor), fluid status (empty inferior vena cava [hypovolemic] vs. full inferior vena cava [not hypovolemic]), and pericardial effusion (present vs. absent). Time from TB to operating room, intravenous fluid administration, blood product requirement, intensive care unit admission, and mortality were examined in both groups. RESULTS: A total of 240 patients were randomized. Twenty-five patients were excluded since they died upon arrival to the TB, leaving 215 patients in the study. Ninety-two patients were in the LTTEp group with 123 patients in the non-LTTE group. The LTTEp and non-LTTE groups were similar in age (38 years vs. 38.8 years, p = 0.75), Injury Severity Score (ISS) (19.2 vs. 19.0, p = 0.94), Revised Trauma Score (RTS) (5.5 vs. 6.0, p = 0.09), lactate (4.2 vs. 3.6, p = 0.14), and mechanism of injury (p = 0.44). Strikingly, LTTEp had significantly less intravenous fluid than non-LTTE patients (1.5 L vs. 2.5 L, p < 0.0001), less time from TB to operating room (35.6 minutes vs. 79.1 min, p = 0.0006), higher rate of intensive care unit admission (80.4% vs. 67.2%, p = 0.04), and a lower mortality rate (11% vs. 19.5%, p = 0.09). Mortality differences were particularly evident in the traumatic brain injury patients (14.7% in LTTEp vs. 39.5% in non-LTTE, p = 0.03). CONCLUSION: LTTE is a useful guide for therapy in hypotensive trauma patients during the early phase of resuscitation. LEVEL OF EVIDENCE: Therapeutic study, level II.

A, B, C, D, echo: limited transthoracic echocardiogram is a useful tool to guide therapy for hypotension in the trauma bay--a pilot study.

BACKGROUND: Limited transthoracic echocardiogram (LTTE) has been introduced as a technique to direct resuscitation in intensive care unit (ICU) patients. Our hypothesis is that LTTE can provide meaningful information to guide therapy for hypotension in the trauma bay. METHODS: LTTE was performed on hypotensive patients in the trauma bay. Views obtained included parasternal long and short, apical, and subxyphoid. Results were reported regarding contractility (good vs. poor), fluid status (flat inferior vena cava [hypovolemia] vs. fat inferior vena cava [euvolemia]), and pericardial effusion (present vs. absent). Need for surgery, ICU admission, Focused Assessment with Sonography for Trauma examination results, and change in therapy as a consequence of LTTE findings were examined. Data were collected prospectively to evaluate the utility of this test. RESULTS: A total of 148 LTTEs were performed in consecutive patients from January to December 2011. Mean age was 46 years. Admission diagnosis was 80% blunt trauma, 16% penetrating trauma, and 4% burn. Subxyphoid window was obtained in all patients. Parasternal and apical windows were obtained in 96.5% and 11%, respectively. Flat inferior vena cava was associated with an increased incidence of ICU admission (p < 0.0076) and therapeutic operation (p < 0.0001). Of the 148 patients, 27 (18%) had LTTE results indicating euvolemia. The diagnosis in these cases was head injury (n = 14), heart dysfunction (n = 5), spinal shock (n = 4), pulmonary embolism (n = 3), and stroke (n = 1). Of the patients, 121 had LTTE results indicating hypovolemia. Twenty-eight hypovolemic patients had a negative or inconclusive Focused Assessment with Sonography for Trauma examination finding (n = 18 penetrating, n = 10 blunt), with 60% having blood in the abdomen confirmed by surgical exploration or computed tomographic scan. Therapy was modified as a result of LTTE in 41% of cases. Strikingly, in patients older than 65 years, LTTE changed therapy in 96% of cases. CONCLUSION: LTTE is a useful tool to guide therapy in hypotensive patients in the trauma bay. LEVEL OF EVIDENCE: Diagnostic study, level III.

Flat inferior vena cava: indicator of poor prognosis in trauma and acute care surgery patients.

Flat inferior vena cava (IVC) on ultrasound examination has been shown to correlate with hypovolemic status. We hypothesize that a flat IVC on limited echocardiogram (LTTE) performed in the emergency room (ER) correlates with poor prognosis in acutely ill surgical patients. We conducted a retrospective review of all patients undergoing LTTE in the ER from September 2010 until June 2011. IVC diameter was estimated by subxiphoid window. Flat IVC was defined as diameter less than 2 cm. Fat IVC was defined as diameter greater than 2 cm. Need for intensive care unit admission, blood transfusion requirement, mortality, and need for emergent operation between patients with flat versus Fat IVC were compared. One hundred one hypotensive patients had LTTE performed in the ER. Average age was 38 years. Admission diagnosis was blunt trauma (n = 80), penetrating trauma (n = 13), acute care surgery pathology (n = 7), and burn (n = 1). Seventy-four patients had flat IVC on initial LTTE. Compared with those with fat IVC, flat patients were found have higher rates of intensive care unit admission (51.3 vs 14.8%; P = 0.001), blood transfusion requirement (12.2 vs 3.7%), and mortality (13.5 vs 3.7%). This population also underwent emergent surgery on hospital Day 1 more often (16.2 vs 0%; P = 0.033). Initial flat IVC on LTTE is an indicator of hypovolemia and a predictor of poor outcome.
