电视腹腔镜子宫切除术与阴式、腹式子宫切除术的临床评价

本文对腹腔境辅助阴式子宫切除术、阴式子宫切除术、腹式子宫切除术三组术式进行信床评价。每组10制，对其手术指征、腹腔镜组、腹式组以子宫肌瘤、卵巢肿瘤为主各为90％、100％，而阴式组则以子宫脱垂为主占100％(P值＜O．001)。腹腔镜组还能同时行胆囊切除术占30％。所切除子宫大小阴式组小于正常子宫占90％。而腹腔境组、腹式组均超过正常子宫大小(P＜0．001)。术后肠功能恢复在24h之内．腹腔镜组占100％、阴式组占80％、腹式组占20％(P＜0．001)。腹腔境组术后无需用镇痛剂。术后住院日腹腔镜组平均5天乏与腹式组平均7．3天比较。P＜0．001。得出腹腔镜辅助阴式子宫切除术兼阴式、腹式子宫切除术的优点。虽然出现2例非损伤性并发症．但只要仔细操作，该项手术在妇科手术领域有很大空间。     

髋关节结核临床治疗的观察（附120例报告）

自１９５８年～１９９６年我院治疗髋关节结核１２０例，随访７４例，平均随访期１４６年，其优良率８１１％。从治疗结果看，为保持关节功能对髋关节结核以早期彻底清除病灶为主，对少数儿童、年老体弱及有手术禁忌症者可采取非手术治疗。对陈旧性结核经病灶清除而留有髋关节畸形者，可作关节成形术，髋关节功能恢复虽不满意，但结核未复发     

443例胃癌根治术后发生肺部并发症的危险因素

目的 探讨胃癌根治术术后肺部并发症(PPCs)的相关危险因素,为PPCs的个体化防治提供相应的对策。 方法 回顾性分析2019年1月至2021年3月兰州大学第二医院普通外科443例胃癌患者的临床资料,统计患者的临床病理特征,采用二分类Logistic回归分析胃癌根治术PPCs的危险因素。 结果 443例胃癌根治术PPCs的发生率为18.1%(80/443),其中肺部感染的发生率为12.4%(55/443),胸腔积液的发生率为11.7%(52/443),发生PPCs较未发生PPCs住院时间延长。Logistic回归分析显示,年龄≥60岁(OR=0.424、95%CI: 0.241~0.746)、糖尿病史(OR=0.318、95%CI: 0.146~0.693)、每分钟最大通气量(MVV)(%)<85%(OR=0.509、95%CI: 0.297~0.874)、术中失血量≥200 mL(OR=0.496、95%CI: 0.276~0.797)和术后吻合口并发症(OR=4.038、95%CI: 1.250~13.049)是胃癌根治术发生PPCs的独立危险因素。 结论 对于年龄≥60岁、糖尿病史、MVV(%)<85%、术中失血量≥200 mL、术后吻合口并发症的胃癌患者,应注意预防PPCs的发生。     

Effects of epidural bupivacaine and epidural morphine on bowel function and pain after hysterectomy

A comparison was made of the effects of continuous epidural analgesia with bupivacaine and intermittent epidural morphine on bowel function after abdominal hysterectomy. The duration of postoperative ileus was assessed as the time from the end of operation to the first postoperative passage of flatus and feces. Twenty-two patients were randomly allocated to two equal groups. An "epidural morphine" group received general anesthesia and epidural morphine for postoperative pain relief, and an "epidural bupivacaine" group was given combined general anesthesia and epidural anesthesia with 0.5% bupivacaine intraoperatively and epidural analgesia with 0.25% bupivacaine postoperatively. Epidural morphine or bupivacaine was given for 42 h postoperatively. Pain intensity (visual analog scale) was low in both groups, but lower (P less than 0.05) in the epidural bupivacaine group. The time to first passage of flatus was 22 +/- 16 h in the epidural bupivacaine group and 56 +/- 22 h in the epidural morphine group (P less than 0.001). The time to first postoperative passage of feces was shorter (P less than 0.05) in the former than in the latter 57 +/- 44 h vs 92 +/- 22 h). The patients of the epidural bupivacaine group started intake of oral fluids earlier (P less than 0.01) and to a greater extent (P less than 0.05) than those in the epidural morphine group. It is concluded that the duration of postoperative ileus after hysterectomy is shorter when epidural bupivacaine is given for postoperative pain relief than when this is achieved by epidural morphine.

目的 :了解子宫切除时宫颈去留对术后性生活质量的影响 ,并观察健康教育干预对提高患者术后性生活质量的作用。方法 :将因子宫良性病变而行子宫切除的病人分为全切组和次切组 ,每组再随机分为干预组和非干预组 ,分别进行术后性生活质量评分比较。结果 :1 在未经心理干预的子宫切除病人中次切组性生活质量评分高于全切组 (P <0 0 5 ) ;2 干预组术后性生活质量评分高于非干预组 (P <0 0 5 )。结论 :子宫切除时保留宫颈及手术前后的健康教育干预有利于患者术后性生活质量的改善     

小径微孔聚氨酯人工血管的顺应性

由激光测微器、压力传感器、A／D卡、微电脑和循环回路等组成的装置测定了小径人工血管的径向顺应性，由微注射器、压力传感器等组成的装置测定了体积顺应性，轴向顺应性由体积顺应性和径向顺应性计算出。体积顺应性，径向顺应性和轴向顺应性都随血管材料弹性的增大、盐／胶比的增加（孔隙率）和浸渍层数（血管壁厚度）的减小而增大。PU血管的外周模量与径向模量分别由径向顺应性。轴向顺应性计算，外周模量与径向模量之比值接近1，即两模量大小与变形方向无关。外周模量与径向模量随血管材料弹性和盐／胶比增加而变小。但管壁厚度对其的影响不大。通过合理选择更具弹性的PU材料（Chro佳，PCU1500次之），最佳盐／胶比例（6：1）以及控制浸渍层数（4～6层），可以制备出顺应性接近天然血管的小径人工血管。     

Fifteen years experience with an in-vitro fertilization surrogate gestational pregnancy programme

The purpose of our study was to review and evaluate retrospectively the experience of an in-vitro fertilization (IVF) surrogate gestational programme in a tertiary care and academic centre. In a 15 year period from 1984 to 1999, a total of 180 cycles of IVF surrogate gestational pregnancy was started in 112 couples. On average, the women were 34.4 +/- 4.4 years of age, had 11.1 +/- 0.72 oocytes obtained per retrieval, 7.1 +/- 0.5 oocytes fertilized and 5. 8 +/- 0.4 embryos subsequently cleaved. Sixteen cycles (8.9%) were cancelled due to poor stimulation. Except for six cycles (3.3%) where there were no embryos available, an average of 3.2 +/- 0.1 embryos was transferred to each individual recipient. The overall pregnancy rate per cycle after IVF surrogacy was 24% (38 of 158), with a clinical pregnancy rate of 19% (30 of 158), and a live birth rate of 15.8% (25 of 158). When compared to patients who underwent a hysterectomy, individuals with congenital absence of the uterus had significantly more oocytes retrieved (P < 0.006), fertilized, cleaved and more embryos available for transfer despite being of comparable age. IVF surrogate gestation is an established, yet still controversial, approach to the care of infertile couples. Take-home baby rates are comparable to conventional IVF over the same 15 year span in our programme. Patients with congenital absence of the uterus responded to ovulation induction better than patients who underwent a hysterectomy, perhaps due in part to ovarian compromise from previous surgical procedures.     

瑞芬太尼与舒芬太尼对老年腹腔镜直肠癌根治术患者围术期血流动力学影响的比较研究

目的探讨瑞芬太尼和舒芬太尼对行腹腔镜直肠癌根治术的老年患者围术期f血流动力学的影响。方法选取2019年9月一2020年6月在北部战区总医院行直肠病根治术的老年患者40例,随机分为I组和II组.各20例。I组给予七氟烷联合瑞芬太尼麻醉,II组给予七氟烷联合舒芬太尼麻醉。观察比较两组围术期各时间点脑电双频指数.血压、心率,以及麻醉恢复期情况。结果两组气腹后血压和心率均升高,I组气腹后5minf血压高于II组,差异有统计学意义(P<0.05)。拔除气管导管后5 min两组血压和心率均较术前升高,而且I组血压和心率均较II组高,差异有统计学意义(P<0.05)。两组不同时间点脑电双频指数值差异均无统计学意义(P>0.05)。I组自主呼吸恢复时间与拔管时间均较I组长,差异有统计学意义(P<0.05)。两组气腹前后呼气末二氧化碳分压差异无统计学意义(P>0.05)。结论瑞芬太尼和舒芬太尼均能满足行腹腔镜直肠癌根治术老年患者的麻醉要求,而且舒芬太尼对患者围术期血流动力学的影响较小,更有利于老年患者术中麻醉的维持与术后恢复。     

根治性膀胱癌切除术后感染切口愈合的危险因素

目的探究根治性膀胱癌切除术后感染切口愈合的危险因素及与单核淋巴细胞因子的关系。方法回顾性选取2015年1月-2018年12月于南阳市中心医院泌尿外科接受根治性膀胱癌切除术治疗的患者作为研究对象,共200例,根据术后切口是否发生感染分为感染组(n=100)和未感染组(n=100),其中感染组根据切口愈合时间分为早期愈合组(n=65)和延迟愈合组(n=35)。对影响根治性膀胱癌切除术后感染切口愈合的因素进行单因素和多因素Logistic回归分析;比较感染组和未感染组血清单核淋巴细胞水平。结果延迟愈合组患者术中出血量高于早期愈合组,白蛋白含量低于早期愈合组,手术时间长于早期愈合组,尿瘘、肠瘘次数均高于早期愈合组(均P<0.05)。经Logistic回归分析,白蛋白、术中出血量、手术时间、尿瘘、肠瘘是影响患者感染切口愈合的独立危险因素(P<0.05)。切口感染组血清肿瘤坏死因子-α(TNF-α)、粒细胞集落刺激因子(G-CSF)、白细胞介素-8(IL-8)、IL-4、IL-6水平高于未感染组(均P<0.05),而IL-2水平低于未感染组(P<0.05)。结论白蛋白、术中出血量、手术时间、尿瘘、肠瘘是影响患者感染切口愈合的独立危险因素,在临床上应采取有针对性的预防控制措施,避免影响术后切口的愈合。同时,对单核淋巴细胞因子的检测有助于防治术后切口感染的发生。
