BACKGROUND: Few studies have examined the association of layperson characteristics with cardiopulmonary resuscitation(CPR) provision. Previous studies suggested provider characteristics, including age and gender, were associated with CPR quality, particularly chest compression(CC) depth. We sought to determine the association of subject characteristics, including age and gender with layperson CPR quality during an unannounced simulated CPR event. We hypothesized shallower CC depth in females, and older-aged ***: As part of a larger multicenter randomized controlled trial of CPR training for cardiac patients' caregivers, CPR skills were assessed 6 months after training. We analyzed associations between subject characteristics and CC rate, CC depth and no-? ow time. Each variable was analyzed independently; signi? cant predictors determined via univariate analysis were assessed in a multivariate regression ***: A total of 521 laypersons completed a 6-month CPR skills assessment and were included in the analysis. Mean age was 51.8±13.7 years, 75% were female, 57% were Caucasian. Overall, mean CC rate was 88.5±25.0 per minute, CC depth was 50.9±2.0 mm, and mean no-flow time was 15.9±2.7 sec/min. CC depth decreased signi? cantly in subjects >62 years(Pjects performed deeper CCs than female subjects(47.5±1.7 vs. 41.9±0.6, P62 years and female gender are associated with shallower CC depth.

目的评价由MRI测得的肝脏-胸廓容积比(LiTR)与伴有孤立性先天性膈疝(CDH)胎儿生后存活率之间的关系。方法在30例保守治疗的CDH及31例行胎儿镜下腔内气管闭塞术(FETO)的胎儿中,应用逻辑回归分析研究胎儿总肺容积(TFLV)的观察/预期(O/E)比、LiTR、分娩时的胎龄、CDH侧、肝脏在胸腔内的位置以及那些行FETO的胎儿当时的胎龄及闭塞的周期对于生后存活率的影响。19例胎儿行FETO,并在FETO术后行MRI检查。与FETO前的TFLV相比,术后3～8周的TFLV的O/E比成比例增加,应用线性回归分析得出其与FETO前LiTR的相关性。结果对于保守治疗的胎儿,仅LiTR对生后存活率的预测有意义。对于行FETO的胎儿,LiTR及分娩时的胎龄对生后存活率均具有独立的预测价值。治疗后的肺应答与FETO前LiTR之间呈显著的负相关。结论在经过或未经过FETO治疗的胎儿中,LiTR可预测生后存活率。在经过FETO治疗的胎儿中,LiTR可预测FETO后的肺应答。要点①先天性膈疝在分娩后、外科治疗前通常行保守治疗。②胎儿镜下腔内气管闭塞术(FETO)已应用于重症CDH的胎儿。③行保守治疗的CDH,肝脏-胸廓容积比(LiTR)可很好地预测生后存活率。④出生前行FETO的重症CDH,LiTR也有助于预测生后存活率。⑤LiTR应该整合到CDH胎儿的产前决策中。

院内心脏骤停期间心肺复苏的质量

世界核心医学期刊文摘（心脏病学分册） 2005年第6期1卷 21-21页

Context: The survival benefit of well-performed cardiopulmonary resuscitation(CPR) is well-documented, but little objective data exist regarding actual CPR quality during cardiac arrest. Recent studies have challenged the notion that CPR is uniformly performed according to established international guidelines. Objectives: To measure multiple parameters of in-hospital CPR quality and to determine compliance with published American Heart Association and international guidelines. Design and Setting: A prospective observational study of 67 patients who experienced in-hospital cardiac arrest at the University of Chicago Hospitals, Chicago, Ill, between December 11, 2002, and April 5, 2004. Using a monitor/-defibrillator with novel additional sensing capabilities, the parameters of CPR quality including chest compression rate, compression depth, ventilation rate, and the fraction of arrest time without chest compressions(no-flow fraction) were recorded. Main Outcome Measure: Adherence to American Heart Association and international CPR guidelines. Results: Analysis of the first 5 minutes of each resuscitation by 30-second segments revealed that chest compression rates were less than 90/min in 28.1%of segments. Compression depth was too shallow(defined as< 38 mm) for 37.4%of compressions. Ventilation rates were high, with 60.9%of segments containing a rate of more than 20/min. Additionally, the mean(SD) no-flow fraction was 0.24(0.18). A 10-second pause each minute of arrest would yield a no-flow fraction of 0.17. A total of 27 patients(40.3%) achieved return of spontaneous circulation and 7(10.4%) were discharged from the hospital. Conclusions: In this study of in-hospital cardiac arrest, the quality of multiple parameters of CPR was inconsistent and often did not meet published guideline recommendations, even when performed by well-trained hospital staff. The importance of high-quality CPR suggests the need for rescuer feedback and monitoring of CPR quality during resusc
