Comparison of local and general anesthesia in tension-free (Lichtenstein) hernioplasty: a prospective randomized trial

To compare pulmonary effects, postoperative pain and fatigue, morbidity, patient satisfaction, and cost of different anesthetic techniques for inguinal hernia repair, 50 patients were randomized to local and general anesthesia groups (LA and GA). All patients received the same premedications and the same postoperative analgesic regimen. The standardized postoperative analgesic, intramuscular pyroxicam 20 mg, was given to all patients in the recovery room and an additional 20 mg on the same day was given as requested by each patient. Pulmonary function studies and arterial blood gas analysis were performed 1 h prior to the operation and at the postoperative 8th and 24th hours. All patients underwent Lichtenstein's tension-free hernioplasty. Postoperative pain and fatigue were registered 8 h and 24 h after the operation. A questionnaire was filled out by the patients, and they were asked to give grades for the general comfort of the anesthesia and the surgical procedure (1=worst, 10=best). Postoperative pulmonary function tests were significantly poorer in the GA group both on 8th- and 24th-hour measurements (P<0.05). Patients who underwent LA had significantly lower PCO₂ and higher PO₂ at the postoperative 8th hour (P<0.05). Mean postoperative pain and fatigue scores revealed a significant difference in favor of local anesthesia at only the 8th hour (P<0.05). There were two complications, one in each group (a hematoma in LA and a urinary retention in GA). Patient satisfaction grades were not different in the two groups. We conclude that LA in inguinal hernia repair does not adversely affect pulmonary functions, patients feel less pain, and patient satisfaction is comparable to that with GA.

细针抽吸活检术诊断脾结核

脾结核发病较少见，临床症状表现也不典型，常易误诊为其他病变如淋巴瘤、脓肿等，影像表现未见特异征象，极易误诊。现将我院收治的3例脾结核临床特点、影像表现进行介绍。特别是在B超或CT引导下的细针抽吸活检术应用，旨在提高对本病认识、及时正确诊断，避免误诊。     

支气管肺蠊缨滴虫病的临床诊治进展

支气管肺蠊缨滴虫感染是一种新的寄生虫疾病,1993年至2008年国内共确诊48例,临床诊断和治疗有一定进展,但蠊缨滴虫感染病例的临床表现缺少特征性,蠊缨滴虫自然宿主、传播途径、流行区域及致病机制等多个方面也尚不明确,其生物学分类地位也有争议,国内还没有建立抗原抗体检测或分子生物学鉴定方法.     

Chronic obstructive pulmonary disease and asthma General and medical management with special attention to exacerbations

The general management of patients with chronic obstructive pulmonary disease and asthma is discussed. Pathophysiological mechanisms of bronchial obstruction and inflammation are briefly described. The importance of preventive measures is emphasized. Medicine prescribed in chronic obstructive pulmonary disease and asthma, their relative place in treatment schedules and route of administration are reviewed. Finally, the importance of maximal bronchodilatation in exacerbations is stressed and the few indications for antibiotic treatment are discussed.     

Th1/Th2炎症极化与肺气肿和肺纤维化

肺气肿具有Ⅰ型T辅助细胞（Th1）炎症极化的特征，表现为损伤过度和修复不足，肺实质的破坏增加，肺间质变薄。与之相反，肺纤维则具有Ⅱ型T辅助细胞（Th2）炎症极化，表现为损伤后修复过度，肺间质增厚，胶原沉积。通过调控Th1和Th2的炎症趋势来控制肺组织的损伤和修复的结局可能会为肺气肿和肺纤维化的防治提供新思路。     

低潮气量治疗在机械通气肺结核术后合并呼吸衰竭患者中的应用

目的 探讨低潮气量维持通气对肺结核术后合并呼吸衰竭患者的应用价值。方法 在有效的抗结核、抗感染治疗的基础上，对32例肺结核术后合并呼吸衰竭患者进行低潮气量（6～8ml／kg）机械通气治疗，观察疗效及并发症。结果 呼吸衰竭治愈31例，死亡1例，治愈率96．9％，无明显并发症。结论 低潮气量维持通气对肺结核术后合并呼吸衰竭患者的治疗是安全的，且疗效显著。     

利福喷汀治疗耐利福平肺结核的疗效分析

目的分析增加利福喷汀的用药剂量对利福平耐药肺结核的疗效，以评价利福喷汀在治疗利福平耐药患者中的作用。方法根据药敏结果选取耐利福平肺结核患者101例，分为治疗1组（利福平低耐），治疗2组（利福平高耐），两组治疗方案中均含利福喷汀，对照组（利福平高耐）治疗方案中不合利福喷汀。观察治疗后3、18个月疗效。结果治疗1组在各阶段的痰菌阴转率、病灶吸收和空洞闭和情况明显优于治疗2组和对照组，两组差异有统计学意义；治疗2组的痰菌阴转率、病灶吸收和空洞闭和情况略优于对照组，两者差异无统计学意义。结论对利福平耐药的患者尤其在利福平低度耐药病例中，可以选择增加利福喷汀用药剂量的方案进行治疗，在利福平高度耐药病例中利福喷汀的作用不能确定。     

固定剂量复合剂在省结核病防治规划中应用的研究
