醫(yī)學論文范文:急性化膿性膽管炎合并心血管疾病的循證麻醉
【摘要】 目的：借助循證醫(yī)學的方法為一例急性化膿性膽管炎合并心血管疾病的老年患者確定麻醉方案。方法：充分評估患者情況后，提出臨床問題，從Cochrane 圖書館(2009年第1期 )、Pubmed(1999年1月-2009年4月)檢索。檢索主題詞為：hypertension， cardiovascular disease，acute suppurative cholangitis，elderly patient，epidural anesthesia，general anesthesia， RCT,human，meta-analysis，systmatic review。結果：共檢索出與麻醉處理相關問題的隨機對照試驗24篇，系統(tǒng)評價12篇。分析文獻后為患者制定合理的麻醉方案。結論：在臨床工作中采用循證方法，結合最佳文獻證據及醫(yī)務人員的臨床經驗和患者的期望值，為急性化膿性膽管炎合并心血管疾病的患者制定理想的治療方案，有效提高麻醉安全性。
【關鍵詞】 心血管疾病;急性化膿性膽管炎;老年患者;麻醉
Evidence-Based Anesthesia for an Acute Suppurative Cholangitis Patient Complicated Cardiovascular DiseaseZENG Wen-jing,LIU Ju-ying (Renmin Hospital of Wuhan University,Wuhan,Hubei 430060;Department of Anesthesiology,Taihe Hospital,Yunyang Medical College,Shiyan,Hubei 442000,China)Abstract:Objective A clinical scheme of anesthesia for an an acute suppurative cholangitis elderly patient complicated cardiovascular disease was made with the evidence-based medicine approach.Methods The situation of patient was fully assessed,the clinical problems were proposea and the information about how to slove the problems was searched in the database of Cochrane library(the first period,2009),PubMed(from January 1999 to April 2009).The searched Medical Subject Headings(MeSH) were:hypertension,cardiovascular disease,acute suppurative cholangitis,elderly patient,epidural anesthesia,general anaesthesia,RCT,human,meta-analysis,systmatic review.Results There were total 24 randomized controlled trials(RCTs) and 12 systmatic reviews correlating with the anesthetic treatment,the clinical scheme was worked out through the analysis of those literatures.Conclusion The evidence-based medicine method,the effective information from literatures,the clinical practise of medical staff combined with the expected value of patients could provide an ideal scheme for acute suppurative cholangitis patients complicated cardiovascular disease,and effectively improve the safety of anesthesia醫(yī).學.全.在.線quanxiangyun.cn.

1 一般資料
1.1 臨床資料患者，女，84歲，因反復右上腹疼痛一周入院。既往有膽囊結石，腦血栓，高血壓病史。入院前行頭孢噻肟和替硝唑抗炎治療一周，緩解后再發(fā)。查體：T 40 ℃，HR 125 bpm，R 20 bpm，BP 125/75 mmHg。神志清楚，精神差，皮膚鞏膜黃染，右上腹壓痛，劍突下和右上腹有明顯壓痛和肌緊張，墨菲征陽性。輔助檢查：白細胞：14.5×109/L，血生化：GPT 539 mmol/L，GOT 1 013 mmol/L，總血膽紅素明顯升高;B超提示：膽囊腫大、膽囊多發(fā)性結石、膽總管擴張。
1.2 評估患者并提出問題
根據患者臨床表現(xiàn)，結合實驗室檢查和體格檢查，參照1983年全國肝膽管結石專題研討會制定的診斷標準，患者急性化膿性膽管炎的診斷成立。術前訪視患者，ASA為3級;根據Goldman非心臟手術病人心血管疾病危險因素評分方法，對此例病人進行分析，得分12分，術前請相關科室會診;根據非心臟手術心血管危險度分層，心血管危險1%～5%(心血管危險度包括心源性死亡及非致命性心肌梗死總發(fā)病率)，屬中危，施行麻醉有一定風險。患者呼吸儲備功能明顯下降，無困難氣道體征。既往有高血壓、腦血栓病史，規(guī)律服用降壓藥及抗凝藥，發(fā)病前血壓維持在150/90 mmHg水平。據此，提出問題：⑴此病人手術時機如何選擇?⑵采取哪種麻醉方式相對安全?⑶用麻醉藥時注意哪些方面?
