骨科择期手术患者压疮危险因素的研究

Objectives：The purposes of the study were to investigate the incidence of pressure ulcer of orthopedics patients undergoing selective operation, and to identify the risk factors of pressure ulcer.Methods: A prospective cohort study was employed in this study. Data were collected concerning the general characteristics as well as preoperative, intraoperative and postoperative indicators probable to induce pressure ulcer and then analyzed in view of the risk factors of pressure ulcer. Results: (1) Pressure ulcers developed in thirty five patients (10.1%) on day 0 and the first 3 days following surgery; (2) age, hemoglobin, lymphocyte and getting up late for the first time after surgery were significantly associated with the occurrence of pressure ulcers (odds ratio 1.068,  0.948, 0.293, 1.019, respectively).Conclusions: (1) Patients have higher risk of developing pressure ulcer after operation, the critical period beginning from the operation day to the 3rd day after operation. (2) The age older, the later getting up for the first time after surgery, the liable it is for the patients to develop pressure ulcer postoperatively.目的 调查骨科择期手术后患者压疮的发生率，分析术后压疮发生的危险因素。方法 采用前瞻性队列研究的方法，样本采用便利取样。记录患者的一般资料、术前、术中和术后可能与压疮发生有一定关系的各项指标，对骨科手术后患者的压疮危险因素进行分析。结果 （1）共35例患者发生了压疮，发生率为10.1%；术后皮肤出现异常的时间均在手术当天至手术后1～3天内；（2）高龄、术前低淋巴细胞总数、术前低血红蛋白含量和术后首次下地时间晚是骨科择期手术后患者发生压疮的危险因素，OR值分别为1.068、0.948、0.293、1.019。结论 （1）骨科择期手术后患者是院内压疮发生的高危人群，其中手术当天至手术后第3天为术后压疮预防的关键时期；（2）年龄越大、术前血红蛋白含量、淋巴细胞总数水平越低及手术后首次下地时间越晚，术后发生压疮的可能性就越大

2-(4-Bromo­phen­yl)-N-(2-methoxy­phen­yl)acetamide

In the title compound, C15H14BrNO2, the 4-bromo­phenyl fragment makes a dihedral angle of 76.55 (17)° with the acetamide unit and the dihedral angle between the two benzene rings is 50.88 (14)°. In the crystal structure, inter­molecular N—H⋯O hydrogen bonds and C—H⋯π contacts connect the mol­ecules, forming chains propagating in [100]
