Single-dose oral omeprazole for reduction of gastric residual acidity in adults for outpatient surgery

Omeprazole is a substituted benzimidazole that causes dose-dependent intracellular inhibition of gastric acid secretion in humans. This double-blind study examined the effect of omeprazole in decreasing gastric acidity and gastric residual volume in outpatient adults. Unpremedicated outpatients, ASA I-III, 18 years or older (n = 17), were randomly assigned to receive omeprazole 80 mg, or placebo by mouth the night before scheduled elective outpatient surgery. The patients were fasted for 8 h prior to surgery. After the patient was anesthetized, an orogastric tube was inserted with proper placement verified by auscultation for gastric sounds. Gastric residual contents were withdrawn into a Luken's trap, and pH was then determined and gastric volume indexed to weight (ml.kg-1). Data were analyzed by a t-test, with P less than 0.05 considered statistically significant. Patient characteristics of both groups were similar. There was a statistically significant difference between the two groups for pH (P = 0.02), but not between the two groups for gastric volume indexed to weight (P = 0.07).     

应用抗凝剂的心脏瓣膜置换患者接受胆道手术的术前处理

目的总结瓣膜置换患者行胆道手术的术前用药方法。方法对38例瓣膜置换后在服用华法令过程中因胆道疾病需行择期手术治疗的患者随机分为2组,肝功能正常组(A组)23例、肝功能不正常组(B组)15例均于术前3d停服华法令,B组术前12h肌注VitK110mg。术前无应用华法令历史的患者115例做为对照组。结果38例患者停药2d后A组血浆凝血酶原时间与对照组差异无显著意义,B组于术前12h肌注VitK110mg后,血浆凝血酶原时间与对照组相比差异也无显著性意义。结论瓣膜置换患者在抗凝期间行胆道手术,只要准备充分,围手术期是安全的。

重症脑出血微创术后下呼吸道感染病原学分析

目的:重症脑出血微创术后气管切开病人痰培养病原菌分布与耐药情况分析,其院内感染发生的原因、探讨防治对策。方法:应用痰培养检出的病原菌及耐药性分析。结果:重症脑出血微创术后气管切开病人下呼吸道感染41例,其中G-杆菌26例占63.4%,G 球菌15例占36.6%,其中金葡菌11例,药敏仍以敏感菌株为主,但耐药菌株有增多趋势。结论:重症脑出血微创术后气管切开病人下呼吸道感染以G-杆菌为主,G 球菌以金葡菌为主,仍以敏感菌珠为主,耐药有增多趋势。万古霉素对G 球菌,氨曲南对G-杆菌敏感性较敏感,故在培养结果未出来之前经验用药是非常重要的。

Slipped upper femoral epiphysis with hemophilia A

A 13-year-old boy who had hemophilia A was reported with pain in the left thigh and hip on walking. He had no history of trauma. Severe hemophilia A is diagnosed with a Factor VIII level of <1 iu/dl. The presumptive diagnosis was that of a spontaneous bleed into the hip joint. Factor VIII mutational analysis revealed a C to G substitution at nucleotide 6683 which results in a cystine change at codon 2194. However, the symptoms persisted and an X-ray demonstrated the presence of an acute on chronic slip of the upper femoral epiphysis. The patient was transferred to the center treating his hemophilia where the hip was pinned in situ under cover with Factor VIII. This case demonstrates the need to be aware of a possible traumatic diagnosis of hip pain in a hemophiliac child with a longstanding history of spontaneous bleeding into joints.     

胆道癌ERCP诊断(附49例分析)

本文报道用ERCP诊断胆管癌24例、胆囊癌6例、壶腹癌19例、共49例,都经手术或病理证实,诊断符合率为85.7％。 文章描述了胆道癌ERCP的X线表现。依造影所见把胆管癌分为阻塞型、狭窄型和息肉型。狭窄型又分闭塞型、环型及弥漫型三个亚型。胆管癌以阻塞型和闭塞型狭窄多见。胆囊癌表现为胆囊内基底宽广固定不变的充盈缺损。壶腹癌为壶腹部边缘不整的占位病变,可阻塞胆管或胰管或同时阻塞胰胆管。肝内胆管的软藤状改变是胆道恶性肿瘤的特征性表现。
