To determine what methods are habitually used by Spanish anesthesiologists to identify the epidural space.
Spanish anesthesiologists were asked to fill in an Internet questionnaire about the methods they had learned during residency training for identifying the epidural space, the method they currently use most often, and the one they consider best for residents to learn during training.
Responses were received from 617 anesthesiologists. The techniques the respondents had learned during training were loss of resistance to air (LOR-A), 58.5%; LOR to saline (LOR-S), 31.9%; LOR and air bubble (LOR-B), 6.1%; and the hanging drop method, 2.4%. Those who had learned the LOR-A technique had changed in 14.2% of the cases, as had 28.4% of those who learned the LOR-S procedure. LOR-A is currently used by 59.2% of the respondents, LOR-S is used by 32.4%, and LOR-B by 6%. The respondents recommended that new residents physicians learn the LOR-A (48.5%) and LOR-S (37.8%) techniques. The LOR-B is recommended by 12.6% a much larger percentage of anesthesiologists than it is habitually used by. Of those who use the LORA technique habitually, 26.4% recommend that new residents use a different procedure.
The procedure used most often by Spanish anesthesiologists to identify the epidural space is the LOR-A technique; however, over a quarter of Spanish users of LOR-A do not recommend it.
确定西班牙麻醉医生习惯性用于识别硬膜外腔的方法。
邀请西班牙麻醉医生填写一份网络调查问卷，内容涉及他们在住院医师培训期间所学的识别硬膜外腔的方法、他们目前最常用的方法以及他们认为住院医师在培训期间最适合学习的方法。
共收到617名麻醉医生的回复。受访者在培训期间所学的技术有：空气阻力消失法（LOR-A），占58.5%；生理盐水阻力消失法（LOR-S），占31.9%；阻力消失与气泡法（LOR-B），占6.1%；以及悬滴法，占2.4%。学习LOR-A技术的人中有14.2%的情况发生了改变，学习LOR-S技术的人中有28.4%的情况发生了改变。目前，59.2%的受访者使用LOR-A，32.4%使用LOR-S，6%使用LOR-B。受访者建议新住院医师学习LOR-A（48.5%）和LOR-S（37.8%）技术。推荐LOR-B技术的占12.6%，这一比例远高于其实际使用比例。在习惯性使用LOR-A技术的人中，有26.4%建议新住院医师使用不同的方法。
西班牙麻醉医生识别硬膜外腔最常用的方法是LOR-A技术；然而，超过四分之一习惯性使用LOR-A技术的西班牙人并不推荐该方法。
