ObjectiveTo evaluate the role of triclosan-coated polyglactin 910 suture in reducing wound infections of emergency gastrointestinal surgeries. MethodsThis was a prospective, randomized, controlled, single center study. From May 2009 to August 2010, 412 patients underwent emergency gastrointestinal operations in our department, 198 of them were chose randomly as experimental group using triclosancoated polyglactin 910 suture for abdominal wall closure， 214 using traditional braiding suture were taken as control. The risk factors for wound healing were analyzed, and wound infection rate was compared between two groups. ResultsThere were no significant differences of gender, age, body mass index, combined diabetes, use of immunosuppressant, and glucocorticoid steroid, type of incision, intraoperative bleeding volume, and operation time between two groups (Pgt;0.05). Wound infection rate of experimental group 〔3.0% (6/198）〕 was significantly lower than that of control group 〔11.7% (25/214), Plt;0.001〕. Especially in subgroup of type Ⅲ incision and operative time more than 120 min, wound infection rate was significantly different between experimental group and control group 〔3.5%(5/141) versus 14.3%(22/154); 3.3%(2/60) versus 21.2%(11/52) respectively, Plt;0.001〕. ConclusionTriclosancoated polyglactin 910 suture can reduce wound infection rate of gastrointestinal emergency operations, especially with type Ⅲ incision and operation time ≥120 min.
目的 探讨急性化脓穿孔性阑尾炎术后切口感染的相关因素。方法 回顾性分析2009年1月至2011年6月期间我院普外科手术治疗的化脓穿孔性阑尾炎161例患者的临床资料。结果 161例患者中35例（21.7%）发生了切口感染。单因素分析结果表明，肥胖（体质指数＞30kg/m2）、手术时间超过1h、术前未预防性应用抗生素及术后首次切口换药时间＞3d者切口感染发生率高（P＜0.05）；多因素分析结果表明，手术时间超过1h及术前未预防性应用抗生素是急性化脓穿孔性阑尾炎术后切口感染的独立危险因素（P＜0.05）。结论 早期诊治、降低手术时间、术前合理预防性应用抗生素有助于减少切口感染机会。
摘要:目的: 探讨在阑尾切除术中应用抗菌薇乔缝线以减少阑尾切口感染的可能性。 方法 : 将我院2007年4月至2009年3月所有阑尾切除术病例1425例随机分为抗菌薇乔缝线组和丝线组,比较其切口感染发生率。 结果 : 统计中按阑尾未穿孔、阑尾穿孔以及总计分别计算切口感染率,在抗菌微乔线组感染率分别为017%、072%、028%,丝线组分别为154%、781%、267%,两组间分别予以X2检验,其〖WTBX〗P 值均小于001,具有显著性差异。 结论 : 缝线是辅助产生切口感染的一个危险因素,在阑尾切除术中使用抗菌薇乔缝线可以显著降低切口感染率。Abstract: Objective: To investigate the application of Coated VICRYL Plus Antibacterial suture in order to reduce the possibility of infection of appendectomy incision. Methods : Hospital from April 2007 to March 2009 appendectomy patients in all 1425 cases were randomly divided into Coated VICRYL Plus Antibacterial suture group and silk group,compared to the incidence of incision infection. Results : The statistics are not in accordance with perforated appendicitis, perforated appendicitis, as well as calculation of the total, respectively, incision infection, the infection rate in the Coated VICRYL Plus Antibacterial suture group were 017%, 072%, 028%, silk group were 154%, 781%, 267% between the two groups separately X2 test, the P value of less than 001, with a significant difference. Conclusion : The suture is to assist the incision produced a risk factor for infection in appendectomy,Coated VICRYL Plus Antibacterial suture can be used in a significant reduction in incision infection rates.
ObjectiveTo review the research on the reasons of unplanned reoperation (URP) for degenerative lumbar spine diseases, and to provide new ideas for improving the quality of surgery for degenerative lumbar spine diseases. Methods The literature about the URP of degenerative lumbar spine diseases at home and abroad in recent years was reviewed and analyzed. Results At present, the reasons for URP include surgical site infection (SSI), hematoma formation, cerebrospinal fluid leakage (CSFL), poor results of surgery, and implant complications. SSI and hematoma formation are the most common causes of URP, which happen in a short time after surgery; CSFL also occurs shortly after surgery but is relatively rare. Poor surgical results and implant complications occurred for a long time after surgery. Factors such as primary disease and surgical procedures have an important impact on the incidence of URP. ConclusionThe main reasons for URP are different in various periods after lumbar spine surgery. Interventions should be given to patients with high-risk URP, which thus can reduce the incidence of URP and improve the surgery quality and patients’ satisfaction.
目的探讨阑尾切除术后腹腔引流放置与否对切口感染的影响。方法回顾性分析1 719例阑尾手术的引流情况和切口感染情况。结果引流组切口感染率为50.93%，未引流组为3.17%(Plt;0.005)。其中单纯性阑尾炎引流组感染率为33.33%，未引流组为1.66%； 化脓性阑尾炎引流组感染率为46.43%，未引流组为3.12%； 坏疽性阑尾炎引流组感染率为56.25%，未引流组为20.00%； 穿孔性阑尾炎引流组感染率为54.95%，未引流组为23.08%。结论无论何种类型阑尾炎，术后放置腹腔内引流均可能增加切口感染。
Objective To evaluate outcomes of vacuum sealing drainage（VSD）for the treatment of wound infection after cardiac surgery.?Methods?We retrospectively analyzed clinical data of 70 patients（with valvular heart disease，congenital heart disease or coronary heart disease）who underwent cardiac surgery via mid-sternotomy and had postoperative wound infection from Jan. 2008 to Jan. 2012 in General Military Hospital of Guangzhou Command. According to different treatment strategy for wound infection, all the patients with wound infection （incision longer than 5 cm） were randomly divided into VSD group （n=35） and control group（n=35） by random number table，while VSD treatment was used for patients in VSD group and routine treatment was used for patients in control group. Treatment outcome，duration of wound infection, duration of antibiotic treatment and treatment cost were compared between the two groups.?Results?There was no in-hospital death in both groups. Wound exudate significantly decreased and fresh granulation tissue grew well in the wound in most VSD group patients after VSD treatment. The cure rate of VSD group was significantly higher than that of control group （94.3% vs. 60.0%，P＜0.05）. Duration of wound infection （12.9±3.4 d vs. 14.8±4.1 d；t=-2.094，P=0.040）and duration of antibiotic treatment （7.0±1.5 d vs. 8.3±1.9 d；t=-2.920，P=0.005） of VSD group were significantly shorter than those of control group. There was no statistical difference in treatment cost between the two groups. Fifteen patients in VSD group were followed up （42.9%） for 3 months with good wound healing, and 20 patients in VSD group were lost in follow-up.?Conclusion?VSD is effective for the treatment of wound infection after cardiac surgery with shortened treatment duration and similar treatment cost compared with routine treatment.
目的 探讨急性阑尾炎手术后切口感染的相关因素。方法 观察我院2002年5月至2007年5月期间收治的665例急性阑尾炎患者采用术前预防使用抗生素、术中保护切口、术后加强切口管理等处理后切口感染情况，并分析切口感染与阑尾炎的病程、手术时间、切口选择、留置引流和病理类型之间的关系。结果 本组患者中32例发生切口感染，感染率为4.81% (32/665)，急性阑尾炎术后切口感染与性别无关（ P ＞ 0.05），与病程长短、切口选择、手术时间、腹腔留置引流与否以及病理类型均有关（ P ＜ 0.01）。结论 病程长、手术时间久、炎症较重的急性阑尾炎病例切口感染率较高； 做好围手术期的处理，术中尽量保护切口可以降低切口感染率。
目的 观察可调节负压引流技术联合局部氧疗治疗腹部切口感染创面的临床效果。 方法 对2009年5月－2012年9月28例腹部切口感染创面患者使用可调节负压引流技术联合局部氧疗治疗，创口内填入负压吸附垫，持续输氧0.5～1 L/min，可调节负压采用连续工作模式，使密闭创面保持60～120 mm Hg（1 mm Hg=0.133 kPa）的负压状态，3～7 d更换负压吸附垫和引流管。 结果 28例切口创面感染得到控制。8例经一次治疗创面愈合，15例经2～4次治疗创面愈合，2例行Ⅱ期缝合，3例患者对贴膜过敏，治疗一次后改为换药治疗。28例患者创面愈合时间4～28 d，平均14 d，随访1～18个月无切口裂开，7例有凹陷瘢痕，余瘢痕平整。 结论 可调节负压引流技术联合局部氧疗治疗腹部切口感染创面，具有操作简便、安全可靠、疗效明显的优点，可加快创面愈合，缩短住院时间，提高切口的愈合质量，减轻患者痛苦及医务人员的工作量。
