Proximal External Aortic Compression for Life-Threatening Abdominal-Pelvic and Junctional Hemorrhage: An Ultrasonographic Study in Adult Volunteers

Introduction: Following life-threatening junctional trauma, the goal is to limit blood loss while expediting transfer to operative rescue. Unfortunately, life-threatening abdominal-pelvic or junctional hemorrhage is often not amenable to direct compression and few temporizing strategies are available beyond hemostatic dressings, hypotensive resuscitation, and balanced transfusion. Objectives: In this study, we evaluated proximal external aortic compression to arrest blood flow in healthy adult men. Methods: This was a simulation trial of proximal external aortic compression, for life-threatening abdominal-pelvic and junctional hemorrhage, in a convenience sample of healthy adult male volunteers. The primary end points were cessation of femoral blood flow as assessed by pulse wave Doppler ultrasound at the right femoral artery, caudal to the inguinal ligament. Secondary end points were discomfort and negative sequelae. Results: Aortic blood flow was arrested in 12 volunteers. Median time to blood flow cessation was 12.5?seconds. Median reported discomfort was 5 out of 10. No complications or negative sequelae were reported. Conclusion: This trial suggests that it may be reasonable to attempt temporization of major abdominal-pelvic and junctional hemorrhage using bimanual proximal external aortic compression. In the absence of immediate alternatives for this dangerous and vexing injury pattern, there appear to be few downsides to prehospital proximal external aortic compression while concomitantly expediting definite care.

Initial improvements in lung function and bronchial hyperresponsiveness are maintained during 5 years of treatment with inhaled beclomethasone dipropionate and terbutaline.

OBJECTIVES: Treatment with inhaled corticosteroids reduces bronchial hyperresponsiveness and relieves airways obstruction in patients with asthma. Up to now, it is unknown whether initial improvements are maintained over a long period of time. Therefore, we assessed whether initial improvements in FEV(1), provocative concentration of histamine causing a 20% fall in FEV(1) (PC(20)), and peak expiratory flow (PEF) persist with a constant dose of inhaled corticosteroids. Furthermore, we investigated whether FEV(1), PC(20), PEF indexes, and symptom scores improve after increasing the dose of inhaled corticosteroids in patients who did not respond sufficiently to treatment with beclomethasone dipropionate (BDP), 800 microg/d. METHODS: Sixty-eight patients with bronchial hyperresponsiveness and airways obstruction completed a previous study on 3 years of treatment with terbutaline, 500 microg qid, and BDP, 200 microg qid. Fifty-eight of these patients participated in the current extension of another 2.5 years of follow-up. Every 6 months, FEV(1) and PC(20) were measured. Five patients dropped out of the study, one for pulmonary reasons. Forty-four patients continued treatment with BDP, 800 microg/d (BDP-800 group), and 9 patients received a higher dose of BDP (500 microg tid; BDP-1,500 group) after the first 3 years because of a rapid decline in FEV(1) (> 50 mL/yr) despite BDP treatment during the previous study period. RESULTS: After the initial improvement, the mean slope of individual regression lines for FEV(1), PC(20), and morning PEF were - 28 mL/yr, - 0.01 doubling concentrations per year, and 0.6 L/min/yr, respectively, in the BDP-800 group. In the BDP-1,500 group, there were no statistically significant improvements in FEV(1), PC(20), PEF indexes, and symptom scores after increasing the dose of BDP. CONCLUSIONS: We conclude that initial improvements in FEV(1), PC(20), and PEF are well preserved over 5 years in patients with obstructive airways diseases who are treated with terbutaline and BDP. In the patients who responded sufficiently to 800 microg/d of BDP, there was no accelerated decline in FEV(1) compared with the general population. Increasing the dose of BDP in a small group of patients with an accelerated fall in FEV(1) (initially treated with a moderate dose of BDP) resulted in no significant improvement in FEV(1), PC(20), PEF indexes, and symptom scores.     

Cardiopulmonary Resuscitation Feedback: A Comparison of Device-Measured and Self-Assessed Chest Compression Quality

BackgroundHigh-quality cardiopulmonary resuscitation is the foundation of cardiac arrest care. Guidelines specify chest compression depth, recoil, and rate, but providers often fail to achieve these targets. Furthermore, providers are largely unable assess the quality of their own or other peoples’ chest compressions. Chest compression feedback devices can improve chest compression quality; their use is endorsed internationally, but they remain largely absent in clinical care.This article analyzes preclinical data collected during a quality improvement project. It describes provider demographics and perceptions about their chest compression quality and correlates them to measured chest compression quality, compares clinician perception of chest compressions to objective measures, and describes the effect of feedback on compression quality.MethodsClinicians were recruited from 2 metropolitan emergency departments. A questionnaire was used to assess participants’ levels of training and experience. A before-and-after assessment of chest compression quality was performed using a Laerdal CPRmeter 2 and a CPR mannequin. Pretest measures of chest compression quality were made by covering the device screen thereby blinding providers to feedback; repeat measures were then collected from the same participants but unblinded to feedback. Provider charecteristic were collected by survey. Correlations between blinded chest compression quality and provider charecteristics; the reliability of providers estimated compared to measured quality; and the effects of feedback on chest compression quality were assessed using Pearsons correlations, Cohens κ, and paired t testing.Results84 participants were assessed. The mean years of certification were 11.74. Ninty-five percent of the providers self-assessed as more experienced than novice and 81% reported performing cardiopulmonary resuscitation at least occasionally. The frequency of performing chest compressions was correlated with self-assessed skill (r = 0.58, P < .001). However, self-assessed skill was only weakly correlated with chest compression quality (r = 0.29, P = .01) and not at all with the frequency of performing chest compressions or years of certification. There was no agreement between self-assessed and device-measured chest compression depth (κ = ?0.10, P = 0.11), recoil (κ = ?0.14, P = .03), or rate (κ = 0.06, P =.30). The overall quality of compressions improved by 16.9%; the percentage of chest compressions achieving target depth by 3.58%; recoil by 22.82%; and rate by 23.66% with feedback. A total of 97.6% of the staff rated chest compression feedback helpful.ConclusionsOur findings suggest that participants’ demographics were not correlated with chest compression quality and that providers cannot reliably assess chest compression quality. The data also demonstrate that with minimal training, feedback can significantly improve chest compression quality.     

Long‐term compliance with endoscopic surveillance for familial adenomatous polyposis

Aim The study assessed compliance of patients with familial adenomatous polyposis (FAP) with endoscopic surveillance. Method In this nationwide, cross‐sectional study, individuals from FAP families registered with the Netherlands Foundation for the Detection of Hereditary Tumours were invited to complete a questionnaire on endoscopic screening experiences. Results A total of 328 individuals were eligible for the study of whom 85 were at risk for FAP, 108 had an intact rectum after a colectomy with ileorectal anastomosis (IRA), and 135 had had a pouch following a proctocolectomy with ileoanal anastomosis (IPAA). Based on medical record data, 20% of the at‐risk group and 26% of the IRA‐group were found to be undercompliant with surveillance advice which was associated significantly with perceived self‐efficacy, use of sedatives during surveillance, pain after surveillance and low perceived benefits of surveillance (P < 0.05). Conclusion One in five individuals at risk for FAP and one in four with a retained rectum are undercompliant with screening advice. We recommend that sedatives should be patient‐tailored for FAP individuals undergoing surveillance and that adequate pain medication be provided after endoscopy.
