背景:在拥挤和陌生的环境中,晕厥和其他短暂的意识丧失发作可能会导致重大的健康危害。尽管有许多出版物,麦加朝圣者的晕厥数据缺乏。
目标:为了确定触发因素,危险因素,以及国内朝圣者中晕厥和其他短暂意识丧失发作的患病率。
方法:这项横断面研究包括了一个方便的国内朝圣者样本,这些朝圣者在2023年7月使用在线GoogleForms问卷(AlphabetInc.,山景,CA).
结果:在388名参与者中,69(18.1%)报告了朝圣期间的晕厥史。其中,57人(82.6%)报告意识完全丧失,56(81.2%)在发作前出现警告症状。49名受访者(71%)中发生了一次晕厥攻击。确定了几个晕厥的诱因,从坐姿突然站立是最普遍的(100%)。其他共同触发因素是拥挤(n=43;62.3%),压力条件(n=30;43.2%),长时间站立(n=21;30.4%),和步行(n=11;15.9%)。据报道,33例(47.8%)因晕厥造成创伤。长时间站立在阿拉法特当天(阿拉法特站立)成为最常见的触发情况(n=48;69.6%)。有多种医学因素导致晕厥发作;最常见的医学解释是中暑(n=48;69.6%),脱水(n=24;34.8%),过度劳累(n=48;69.6%),低血糖(n=10;14.5%),和低血压(n=17;24.6%)。重要的预测因素是心脏病的存在(奇数比(OR)7.6,95%置信区间(CI)2.71-21.45,p<0.001),贫血(OR2.5,95%CI1.01-6.09,p=0.049),既往晕厥(OR2.5,95%CI1.02-6.27,p=0.049,以及晕厥家族史(OR10.1,95%CI2.08-49.32,p=0.004)。
结论:国内朝圣期间晕厥频繁,尤其是在阿拉法特的日子,并有外伤的危险.以前有晕厥和合并症发作的人,尤其是心脏病患者和有晕厥家族史的人,特别容易出现这种风险。医疗保健应该专注于有风险的患者,特别是在关键的朝圣日,并提高朝圣者对晕厥诱因的认识,包括突然和长时间站立,努力,和热暴露。
BACKGROUND: Syncope and other transient loss of consciousness episodes in crowded and unfamiliar environments may lead to major health hazards. Despite numerous publications, data on syncope among
Hajj pilgrims in Makkah is lacking.
OBJECTIVE: To identify the triggers, risk factors, and prevalence of syncope and other transient loss of consciousness episodes among domestic pilgrims.
METHODS: This cross-sectional study included a convenient sample of domestic pilgrims who performed
Hajj in July 2023 using an online Google Forms questionnaire (Alphabet Inc., Mountain View, CA).
RESULTS: Out of 388 participants, 69 (18.1%) reported a history of syncope during the
Hajj pilgrimage. Among these, 57 (82.6%) reported complete loss of consciousness, and 56 (81.2%) noted warning symptoms preceding the episode. The syncopal attack occurred once in 49 respondents (71%). Several triggers for syncope were identified, with sudden standing from a sitting position being the most prevalent (100%). Additional co-triggers were crowding (n=43; 62.3%), stressful conditions (n=30; 43.2%), prolonged standing (n=21; 30.4%), and walking (n=11; 15.9%). Traumatic injuries were reported in 33 (47.8%) as a result of syncope. Standing for long periods of time on the day of Arafat (Arafat standing) emerged as the most common triggering situation (n=48; 69.6%). There were multiple medical factors contributing to syncopal episodes; the most common medical explanations were heat exhaustion (n=48; 69.6%), dehydration (n=24; 34.8%), over-exertion (n=48; 69.6%), low blood sugar (n=10; 14.5%), and low blood pressure (n=17; 24.6%). Significant predictors were the presence of cardiac disease (odd ratio (OR) 7.6, 95% confidence interval (CI) 2.71-21.45, p<0.001), anemia (OR 2.5, 95% CI 1.01-6.09, p=0.049), previous syncope (OR 2.5, 95% CI 1.02-6.27, p=0.049, and family history of syncope (OR 10.1, 95% CI 2.08-49.32, p=0.004).
CONCLUSIONS: Syncope during the domestic
Hajj pilgrimage is frequent, especially on the day of Arafat, and carries the risk of traumatic injury. People with previous episodes of syncope and comorbidities, especially cardiac patients and those who have a family history of syncope, are particularly prone to this risk. Healthcare should focus on at-risk patients, particularly on critical pilgrimage days, and increase pilgrims\' awareness about triggers of syncope including sudden and prolonged standing, exertion, and heat exposure.
