Current management recommendations for equipment-laden athletes in sudden cardiac arrest regarding whether to remove protective sports equipment before delivering cardiopulmonary resuscitation are unclear.
To determine the effect of men's lacrosse equipment on chest compression and ventilation quality on patient simulators.
Cross-sectional study.
Controlled laboratory.
Twenty-six licensed athletic trainers (18 women, 8 men; age = 25 ± 7 years; experience = 2.1 ± 1.6 years).
INTERVENTION(S): In a single 2-hour session, participants were block randomized to 3 equipment conditions for compressions and 6 conditions for ventilations on human patient simulators.
MAIN OUTCOME MEASURE(S): Data for chest compressions (mean compression depth, compression rate, percentage of correctly released compressions, and percentage of optimal compressions) and ventilations (ventilation rate, mean ventilation volume, and percentage of ventilations delivering optimal volume) were analyzed within participants across equipment conditions.
Keeping the shoulder pads in place reduced mean compression depth (all P values < .001, effect size = 0.835) and lowered the percentages of both correctly released compressions ( P = .02, effect size = 0.579) and optimal-depth compressions (all P values < .003, effect size = 0.900). For both the bag-valve and pocket masks, keeping the chinstrap in place reduced mean ventilation volume (all P values < .001, effect size = 1.323) and lowered the percentage of optimal-volume ventilations (all P values < .006, effect size = 1.038). Regardless of equipment, using a bag-valve versus a pocket mask increased the ventilation rate (all P values < .003, effect size = 0.575), the percentage of optimal ventilations (all P values < .002, effect size = 0.671), and the mean volume ( P = .002, effect size = 0.598) across all equipment conditions.
For a men's lacrosse athlete who requires cardiopulmonary resuscitation, the shoulder pads should be lifted or removed to deliver chest compressions. The facemask and chinstrap, or the entire helmet, should be removed to deliver ventilations, preferably with a bag-valve mask.
目前对于突发心搏骤停且装备齐全的运动员，在进行心肺复苏前是否去除防护性运动装备，相关管理建议并不明确。
确定男子曲棍球装备对模拟患者的胸外按压和通气质量的影响。
横断面研究。
受控实验室。
26 名有执照的运动训练师（18 名女性，8 名男性；年龄=25±7 岁；经验=2.1±1.6 年）。
在一个 2 小时的单一疗程中，参与者按块随机分为 3 个设备条件进行胸外按压和 6 个设备条件进行通气，在人体模拟患者上进行。
对设备条件下的胸外按压（平均按压深度、按压频率、正确释放按压的百分比和最佳按压的百分比）和通气（通气频率、平均通气量和最佳通气量的百分比）数据进行了参与者内分析。
保持肩垫就位会降低平均按压深度（所有 P 值均＜.001，效应量=0.835），并降低正确释放按压的百分比（P=0.02，效应量=0.579）和最佳深度按压的百分比（所有 P 值均＜.003，效应量=0.900）。对于球囊面罩和口咽通气道，保持下颌带就位会降低平均通气量（所有 P 值均＜.001，效应量=1.323），并降低最佳通气量的百分比（所有 P 值均＜.006，效应量=1.038）。无论设备如何，使用球囊面罩而不是口咽通气道都会增加通气频率（所有 P 值均＜.003，效应量=0.575）、最佳通气的百分比（所有 P 值均＜.002，效应量=0.671）和平均通气量（P=0.002，效应量=0.598）。
对于需要心肺复苏的男子曲棍球运动员，应抬起或移除肩垫以进行胸外按压。应移除面罩和下颌带，或整个头盔，以进行通气，最好使用球囊面罩。
