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.

肺心病患者血清碱性成纤维细胞生长因子水平的变化及其与肺动脉压的关系

目的　探讨碱性成纤维细胞生长因子 (b FGF)在低氧性肺动脉高压发病中的作用。方法　采用酶联免疫吸附法对具有低氧性肺动脉高压的肺心病患者 2 1例、无低氧性肺动脉高压的慢性阻塞性肺疾病 (COPD)患者 2 3例和 2 4例正常人血清 b FGF水平进行检测 ,以多普勒超声心动仪测定肺心病和 COPD患者的平均肺动脉压 (m PAP)。结果　肺心病组 m PAP水平 (33.33± 7.0 3m m Hg)明显高于 COPD组 (13.13± 2 .34mm Hg) ,P<0 .0 0 1;肺心病组血清 b FGF水平 (6 9.84± 16 .2 9pg/m l)明显高于 COPD组 (43.94± 7.5 7pg/ml)和正常对照组(44 .6 4± 6 .31pg/m l) ,P<0 .0 0 1;肺心病血清 b FGF水平与 m PAP之间呈明显正相关 ,r=0 .730 ,P<0 .0 0 1。结论慢性肺心病患者血清 b FGF水平明显升高 ,可能与其慢性低氧性肺动脉高压的形成有一定的关系。     

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。     

X线引导下支气管动脉栓塞治疗肺结核空洞咯血的一些体会

肺结核空洞大咯血来势凶猛,是常见的临床急症之一。常规内科止血效果不佳,而外科治疗对身体侵袭太大且受诸多因素影响常受限制。栓塞参与出血的支气管动脉及体动脉的其他分支是治疗急、慢性咯血安全有效并可重复进行的微创介入治疗方法犤1犦。1977年R em y首次报道选择性支气管     

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.     

经前后路联合手术治疗L5S1椎体结核

目的 探讨一期经前路病灶清除后路植骨内固定治疗L5S1椎体结核的临床疗效.方法 对40例L5S1椎体结核患者,采用一期经前路病灶清除椎体间植骨加后路椎弓根螺钉内固定植骨融合治疗.结果 所有患者随访6～24个月,35例植骨融合良好,5例融合欠佳;有1例出现尿路感染.结论 一期经前路病灶清除椎体间植骨加后路椎弓根螺钉内固定椎板植骨治疗L5S1椎体结核能在彻底清除病灶的前提下保证脊柱的稳定性,提高植骨块的融合率和缩短患者卧床时间.

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。

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。
