目的:了解骨盆或髋臼骨折患者术前灌肠的现状，以及骨科医师对灌肠这一术前准备措施的看法，以期指导临床治疗。方法:2019年9月以微信问卷星形式进行横断面调查，调查问卷发给1 000名全国各地的骨科医师，涉及的内容为参与调查者职称、所在单位级别，调查的问题包括：①在进行骨盆或髋臼骨折手术前是否会给患者灌肠？②如果术前给患者灌肠，会选择何种方式？③给患者进行术前灌肠的目的是什么？④如果术前不给患者灌肠，理由是什么？等等。按参与调查医师所在医院等级不同（二级医院和三级医院）做分层分析。结果:共有704名来自全国各地的骨科医师完成了本次调查，其中三级医院506名（71.88%，506/704），二级医院198名（28.13%，198/704）。调查结果显示：41.90%（295/704）的医师在术前会给患者灌肠，但选择“不灌肠”（26.99%，190/704）和“不一定”（31.11%，219/704）的医师也很多。对于主张灌肠的医师，灌肠的目的主要是为了“排除肠气，使术中透视更为清晰”（77.04%，396/514）。对于不支持灌肠的医师，反对这一措施的主要原因是“会增加患者的痛苦”（76.84%，146/190）。与三级医院比较，二级医院的医师进行术前灌肠、选择机械性灌肠的比例更高，同时，更高比例的二级医院医师认为灌肠可以减少患者并发症的发生，也可以使术中透视更为清晰。结论:目前国内一些医师、特别是三级医院医师在骨盆或髋臼骨折手术前不对患者进行灌肠。“,”Objective:To investigate the current situation of preoperative enema in patients with pelvic or acetabular fracture and how orthopedists think about enema as a preoperative preparation so as to provide clinical guidance.Methods:In a cross-sectional survey conducted in September 2019 in the form of Wechat Questionnaire Star, a questionnaire was sent to 1,000 orthopedists all over the country. The items surveyed included the professional title and the hospital level of the participants. The questions asked included: 1. Will enema be performed for a patient with pelvic or acetabular fracture before surgery? 2. If enema is given to a patient before surgery, what method will you choose? 3. What is your purpose of preoperative enema for patients? 4. What are your reasons for not giving a patient enema before surgery? Stratified analysis was conducted by the hospital levels of the participants.Results:A total of 704 orthopedists from all over the country completed the present survey. The questionnaires finished came from 506 (71.88%, 506/704) tertiary hospitals and 198 (28.13%, 198/704) secondary hospitals. The survey showed that 41.90% of the orthopedists (295/704) would give their patients enema before surgery, 26.99% (190/704) would not and 31.11% (219/704) would not necessarily. The main purpose of enema in the orthopedists who advocated enema was to eliminate intestinal gas so as to make intraoperative fluoroscopy more clearly (77.04%, 396/514); the main reason against this measure in those who did not support enema was that it would increase the pain of patients (76.84%, 146/190). Compared with the tertiary hospitals, a higher proportion of orthopedists in the secondary hospitals would perform preoperative enema and choose mechanical enema. Moreover, a higher proportion of orthopedists in the secondary hospitals believed that enema could reduce complications and make intraoperative fluoroscopy clearer.Conclusion:At present, a number of orthopedists in China, especially those in a tertiary hospital, do not give their patients enema before surgery of pelvic or acetabular fracture.
