【摘要】：背景:膝骨性關節(jié)炎是一種在中老年人群中較為常見的慢性退行性疾病。目前人工膝關節(jié)置換術(TKA)作為一種成熟的技術已經廣泛應用于中晚期膝骨性關節(jié)炎的治療,其療效也己經被證實確切可靠。TKA術后截骨面及髓腔內的出血量較大,部分患者術后不可避免需要進行異體輸血。但目前臨床上出現(xiàn)的用血緊張現(xiàn)象及難以避免的輸血窗口期感染疾病的風險,一直對患者及臨床醫(yī)生造成困擾。因此臨床上一直希望能夠找到一種新的方法來減少手術創(chuàng)傷帶來的失血,降低術后的輸血概率及相應帶來的輸血風險。目前國內外有多篇報道于TKA術中靜脈或局部使用氨甲環(huán)酸均可降低術后失血量。但目前術中氨甲環(huán)酸如何使用可取得最佳的效果并無統(tǒng)一意見。對于氨甲環(huán)酸用于局部關節(jié)腔內使用與靜脈使用的效果孰優(yōu)孰劣也一直有不少爭議。國內外雖然對該此有不少相關研究及報道,但目前并沒有統(tǒng)一的結論。局部關節(jié)腔內使用氨甲環(huán)酸需在手術結束后大部分都會對負壓引流管夾閉一段時間,其目的是減少局部的氨甲環(huán)酸的流失,并盡可能的產生最大的藥物效應。故本研究夾閉引流管3小時的情況下采用關節(jié)腔內局部注射氨甲環(huán)酸,以盡量延長藥物的作用時間。目的:比較全膝關節(jié)置換術中關節(jié)腔內局部氨甲環(huán)酸使用方法的臨床療效。方法:將2013.4-2014.11期間蘇州大學附屬常熟市第一人民醫(yī)院骨科66例患膝關節(jié)骨性關節(jié)炎擬行單側人工全膝關節(jié)置換術的患者,其中男性為18例,女性為48例,采用隨機的方法分為三組,A組21例,B組23例,C組22例,A組患者術中使用局部浸潤氨甲環(huán)酸治療,在安裝假體結束后,縫合表面支持帶后,夾閉負壓引流,將1g氨甲環(huán)酸注射液直接注射于關節(jié)腔內。術后引流管保持夾閉3小時。B組患者于松開止血帶前10分鐘靜滴氨甲環(huán)酸1g,術后同樣夾閉負壓引流3小時。C組不使用氨甲環(huán)酸,術后同樣夾閉負壓引流3小時。術中根據(jù)出血量,患者心跳,血壓等一般情況綜合考慮是否輸血。三組患者均于術后24小時拔除負壓引流管�；颊咝g后當血常規(guī)Hb小于70g/L予輸紅懸糾正貧血,70至80g/L之間時,根據(jù)患者當時一般情況以及是否存在明顯的貧血癥狀決定是否進行輸血治療。記錄的數(shù)據(jù)如下:術中失血量,患者術前及術后96h時Hb及HCT,術后24h內負壓管血性液引流量,術前及術后3小時后凝血功能指標變化(含D2聚體,纖維蛋白原、活化部分凝血活酶時間以及凝血酶原時間),術后患肢腫脹程度變化(髕上10cm周徑變化),術后患肢疼痛評分變化,術后需要輸血患者例數(shù)及輸血量,術后2周時膝關節(jié)Hss評分,下肢靜脈血栓或肺栓塞情況。使用SPSS19.0(社會科學統(tǒng)計軟件包)對以上采集的臨床數(shù)據(jù)進行統(tǒng)計學數(shù)據(jù)分析,計量資料如經過檢驗符合正態(tài)分布的標準,則采用(χ±S)表示。組間數(shù)據(jù)兩兩比較采用單因素分析的方法。如檢驗后不符合正態(tài)分布的標準,則采用四分位數(shù)表達。三組患者性別,輸血比例采用卡方檢驗,如最小理論頻數(shù)小于5,則使用Fisher確切概率法對所得的數(shù)據(jù)進行分析,如P0.05則考慮有顯著性的差異。結果:①術后24h內負壓管血性液引流量比較結果:A組B組C組三組間術后24h內血性液引流量比較結果,P值均0.05,有統(tǒng)計學意義。②術后96h時隱性失血量比較結果:A組和B組術后隱性失血量比較結果,P0.05,無統(tǒng)計學意義。A組B組分別與C組比較,P值均0.05,有統(tǒng)計學意義。③術后96h時總體失血量比較結果:A組B組C組三組間術后總失血比較結果,P值均0.05,有統(tǒng)計學意義。④A組B組C組三組間術后FDPS,PT,APTT比較結果,P值均0.05,無統(tǒng)計學意義。A組和B組術后D二聚體比較結果,P0.05,無統(tǒng)計學意義。A組B組D二聚體結果分別與C組比較,P值均0.05,有統(tǒng)計學意義。⑤術后患肢1天及4天時腫脹程度變化比較結果:A組和B組術后患肢髕上10cm周徑程度變化比較結果,P0.05,無統(tǒng)計學意義。A組B組分別與C組比較,P值均0.05,有統(tǒng)計學意義。⑥術后患肢24h,48h,96 h靜息疼痛評分變化比較結果:A組B組C組三組間術后患肢疼痛評分比較結果,P值均0.05,無統(tǒng)計學意義。⑦術后2周時膝關節(jié)Hss評分比較結果:A組B組C組三組間術后2周Hss評分比較結果,P值均0.05,無統(tǒng)計學意義。⑧需要輸血患者比例比較結果:A組和B組術后需要輸血患者比例比較結果,P0.05,無統(tǒng)計學意義。A組B組分別與C組比較,P值均0.05,有統(tǒng)計學意義。結論:全膝關節(jié)置換術中關節(jié)腔內局部使用氨甲環(huán)酸可以減低術后出血量及輸血的概率。且并不會增加術后發(fā)生靜脈栓塞的概率。
[Abstract]:Background: knee osteoarthritis is more common in the elderly population of chronic degenerative diseases. The total knee arthroplasty (TKA) as a kind of advanced technology has been widely used in the treatment of knee osteoarthritis, its curative effect has been proved to be exact and reliable bleeding after.TKA the surface of the osteotomy and intramedullary greatly, some patients need blood transfusion. But the inevitable risk of current clinical use of blood and nervous phenomena appear difficult to avoid blood transfusion infection in window period of the disease, has been caused by the troubled patients and clinicians. So we always hope to be able to find a new method to reduce surgical trauma caused by blood loss, reduce the probability of postoperative blood transfusion and bring the risk of blood transfusion. There are several reports on intravenous TKA operation or topical use of tranexamic acid can reduce the postoperative loss But the current volume. Intraoperative tranexamic acid can be used to obtain the best effect. There is no unified opinion for tranexamic acid for local intra-articular and intravenous use of the effect of the merits has also been a lot of controversy. Although many of the related studies and reports, but there is no unified conclusion local intra-articular use of tranexamic acid in the end of the operation are mostly on negative pressure drainage pipe clamp for a period of time, the purpose is to reduce the partial loss of tranexamic acid, and as far as possible to produce the biggest effect of drugs. Therefore, the study of closed drainage for 3 hours under the condition of the use of intra-articular local injection of tranexamic acid, so as to prolong the time of drug action. Objective: To compare the clinical effect of total knee arthroplasty in intra-articular local tranexamic acid use. Methods: during the period of 2013.4-2014.11 in Suzhou Department of orthopedics, the first people's Hospital of Changshou City affiliated to study 66 patients with knee osteoarthritis underwent unilateral total knee arthroplasty patients, including 18 cases of male, female 48 cases, were randomly divided into three groups and 21 cases in A group, 23 cases in B group, C group of 22 cases, the use of local the infiltration of tranexamic acid in the treatment of patients in the A group, in the installation of prosthesis after suture with support surface after clamping the negative pressure drainage, Tranexamic Acid Injection 1g will directly injected into the articular cavity. Keep the tube clamping 3 hour.B patients on tourniquet release 10 minutes before the intravenous drip of tranexamic acid 1g postoperative drainage, postoperative the same clamping drainage for 3 hours in group.C without the use of tranexamic acid, after the same clamping drainage for 3 hours. According to the intraoperative bleeding, blood pressure in patients with heart, generally considered whether blood transfusion. Three groups of patients in the 24 hours after removal of negative pressure drainage tube. When the blood of patients after operation The conventional Hb is less than 70g/L to lose the red suspension for correction of anemia, between 70 and 80g/L, according to the patient at the time the general situation and the existence of obvious symptoms of anemia, determine whether blood transfusion treatment. The data recorded are as follows: the intraoperative blood loss, Hb and HCT in patients with preoperative and postoperative 96h, negative pressure drainage tube bloody 24h after the operation, preoperative and postoperative 3 hours after the change of coagulation index (including D2 dimer, fibrinogen, activated partial thromboplastin time and prothrombin time), changes of postoperative limb swelling (10cm patellar circumference), postoperative limb pain score changes, postoperative blood transfusion and the number of patients, 2 weeks after operation Hss knee score, lower extremity venous thrombosis or pulmonary embolism. Using SPSS19.0 (statistical package for Social Science) for statistical data analysis of the clinical data collected over the measurement data, such as through the test are consistent with the 鎬佸垎甯冪殑鏍囧噯,鍒欓噰鐢，
