[目的]评价在现代血液管理策略干预下,术中自体血回输在初次单侧全髋关节置换术(total hip arthro-plasty,THA)快速康复中的安全性和有效性。[方法]设定纳入与排除标准,回顾性纳入2015年1月~2016年1月,于四川大学华西医院关节外科行初次单侧THA的患者130例,其中手术过程中使用了自体血液回输装置的70例患者作为回输组,未使用的60例患者作为对照组。[结果]两组患者的凝血功能、炎性指标和术后并发症的发生率差异无统计学意义(P>0.05)。回输组的术中出血量多于对照组[(259.73±189.50)ml vs(118.25±56.47)ml,P<0.001],术后24 h引流量多于对照组[(274.43±153.31)ml vs(193.64±88.62)ml,P=0.031],两组患者术后第1 d的血红蛋白(hemoglobin,HB)和血细胞比容(hematocrit,HCT)下降量差异无统计学意义(P>0.05),术后贫血发生率差异无统计学意义(P=0.558),回输组术后第3 d的HB和HCT下降量多于对照组(P<0.05),异体输血率差异无统计学意义(4.29%vs 0%,P=0.300)。[结论]基于快速康复外科理念,在现代血液管理策略干预下,对于术中出血量多、手术时间长的复杂初次单侧THA,术中自体血回输不会改变患者的凝血功能和炎性指标,不会增加术后并发症的发生率。术中自体血回输可以减少患者血红蛋白的丢失,防止HB和HCT快速下降,降低术后贫血的发生率。  相似文献

背景:静脉及局部应用氨甲环酸(tranexamic acid,TXA)均能有效减少全髋关节置换术(total hip arthroplasty,THA)围术期出血量及输血率。但局部应用TXA是否能与静脉应用同等剂量TXA的止血效果相当尚不明确。目的:对比THA中局部应用TXA与静脉应用同等剂量TXA的止血效果。方法:2017年1月至2017年12月前瞻性纳入拟行初次单侧THA的患者116例,随机分为2组,每组58例。静脉组:皮肤切开前10 min给予静脉输注1 g TXA,3 h后再次静脉输注1 g TXA。局部组:术中及关闭切口前局部应用总剂量2 g的TXA。有效性指标包括围术期总失血量、输血率、引流量、术后第1日及第3日血红蛋白(hemoglobin,Hb)下降值;安全性指标包括深静脉血栓(deep vein thrombosis,DVT)及肺栓塞(pulmonary embolism,PE)发生率。结果:局部组患者的围术期平均总出血量、平均术后引流量、术后第1日及第3日Hb下降值均高于静脉组,均有统计学差异(P<0.05)。局部组患者的输血率高于对照组,但无统计学差异(P>0.05)。两组DVT发生率无统计学差异,两组均未发生PE。结论:THA中局部应用2 g TXA不能达到静脉应用2 g TXA相同的止血效果,若预期达到与静脉应用TXA相同的止血效果,可能需要局部应用更高剂量的TXA。  相似文献

Background

Fibrin sealants are topical agents used to reduce perioperative blood loss; however, their efficacy in total hip arthroplasty (THA) remains uncertain. The purpose of this study was to determine if a fibrin sealant containing aprotinin as an antifibrinolytic agent, TISSEEL (Baxter, Deerfield, IL), reduces postoperative blood loss and transfusion during THA when compared with intravenous (IV) tranexamic acid (TXA) and control groups.

Methods

Three retrospective uniform cohorts of primary THA procedures were identified, from a prospectively maintained database: 1 group who received TISSEEL, 1 group who received 1 g IV TXA, and 1 group who received neither (control). There were 80 patients in each group. Outcome measures included the lowest measured hemoglobin during postoperative hospitalization, greatest decrease in hemoglobin from preoperative to postoperative values, and blood transfusion rates.

Results

The minimum postoperative hemoglobin level was significantly lower for TISSEEL patients compared with that of IV TXA patients (P = .021) and no different when compared with that of control patients (P = .134). Patients receiving fibrin sealant had a greater hemoglobin level decrease compared with that of IV TXA (P = .029) and control (P = .036). Postoperative transfusion rates were no different for the group receiving TISSEEL compared with those of control (P = .375) and were statistically greater when compared with those of IV TXA (P = .002).

Conclusion

TISSEEL fibrin sealant does not reduce postoperative blood loss or transfusions; however, IV TXA reduced postoperative transfusions compared with TISSEEL and control. Therefore, TXA is recommended to reduce perioperative blood loss, while, utilization of a fibrin sealant requires further refinements before being adopted for routine use in THA.  相似文献

BackgroundTo evaluate the transfusion rates for octogenarians and nonagenarians following total knee and hip arthroplasty (TKA, THA), we compared transfusion rates and associated risk factors among sexagenarians, septuagenarians, octogenarians, and nonagenarians.MethodsThis retrospective cohort study included 13,603 sexagenarians, 9796 septuagenarians, 2706 octogenarians, and 158 nonagenarians that received a primary, unilateral THA or TKA between 2016 and 2020 at a high-volume institution. Using multivariable logistic regression analysis, the study analyzed risk factors for postoperative transfusions including use of tranexamic acid (TXA) and compared preoperative and postoperative hemoglobin (Hgb) levels and the drop in Hgb.ResultsNonagenarians had significantly higher transfusion rates (THA 25.5%, TKA 26.7%) than octogenarians (THA 9.9%, TKA 9.2%), septuagenarians (THA 3.3%, TKA 4.5%), and sexagenarians (THA 1.9%, TKA 2.9%) (P < .01). Significant risk factors for transfusion requirement following THA were American Society of Anesthesiologists level III (odds ratio [OR] 5.3, P < .01) and American Society of Anesthesiologists level IV (OR 8.0, P = .01), nonuse of TXA (intravenous: OR 0.3, P < .01; topical: OR 0.5, P < .01), lower preoperative Hgb levels (OR 0.4, P < .01), longer duration of surgery (OR 1.0, P < .01), and hepatopathy (OR 3.1, P < .01). Significant risk factors following TKA were nonuse of TXA (intravenous: OR 0.3, P < .01; topical: OR 0.5, P < .01; combined: OR 0.2, P < .01), lower preoperative Hgb levels (OR 0.4, P < .01), and longer surgery time (OR 1.0, P < .01).ConclusionThe strongest independent risk factors for increased transfusion rates among octogenarians and nonagenarians were lack of TXA application and lower preoperative Hgb levels. Routine TXA application and preoperative patient optimization are recommended to reduce transfusion rates in patients aged 80+.  相似文献

The objective of this study was to determine if tranexamic acid (TXA) applied topically reduced postoperative bleeding and transfusion rates after primary total hip arthroplasty (THA) and primary total knee arthroplasty (TKA). Two hundred and ninety consecutive patients from a single surgeon were enrolled. In TKA, TXA solution was injected into the knee after closure of the arthrotomy. In THA, the joint was bathed in TXA solution at three points during the procedure. In both THA and TKA the TXA solution was at a concentration of 3 g TXA per 100 mL saline. The mean blood loss was significantly higher in the non-TXA patients in both TKA and THA groups. Postoperative transfusions decreased dramatically with TXA, dropping from 10% to 0%, and from 15% to 1%, in the TKA and THA groups, respectively. Topical application of TXA significantly reduces postoperative blood loss and transfusion risk in TKA and THA.  相似文献

Background

The mode of administration for tranexamic acid (TXA) to significantly reduce the decrease in hemoglobin (Hb), number of transfusions, relevant costs, and side effects in patients undergoing primary unilateral total knee arthroplasty (TKA) has not been resolved.

Methods

A total of 560 patients undergoing primary unilateral TKA were randomized into 4 groups: intravenous group (140 patients receiving 2 doses of 20 mg/kg intravenous TXA), topical group (140 patients administered 3.0 g topical TXA), oral group (140 patients given 2 doses of 20 mg/kg oral TXA), and a control group (140 patients not given TXA). The primary outcomes included postoperative 48-hour Hb loss and drainage volume, number of transfusions, transfusion and TXA costs, and thromboembolic complications. Secondary outcomes were postoperative inpatient time and wound healing 3 weeks after TKA.

Results

Baseline data among the 4 groups were similar. The 48-hour Hb loss and drainage volume in the intravenous, topical, and oral groups were significantly less (P < .05) than those in the control group, and the latter had significantly more transfusions and transfusion costs than the other 3 groups (P < .05). The TXA cost was lowest in the oral group compared with that in the topical and intravenous groups (P < .05). No differences in thromboembolic complications, postoperative inpatient time, or wound healing were observed among the groups. However, wound dehiscence and continuous wound discharge occurred in the topical group.

Conclusion

All the 3 modes of TXA administration significantly reduced postoperative Hb loss, the number of transfusions, and transfusion costs compared with those in the control group. No pulmonary embolism or infection was observed. Oral TXA is recommended because it provided a similar clinical benefit and resulted in the lowest TXA cost compared with the other 2 modes of TXA administration.  相似文献

PurposeBlood loss during and following elective total hip arthroplasty (THA) can be substantial and may require allogeneic blood transfusions which carries significant risks and morbidity for patients. Intraoperative use of tranexamic acid (TXA) has been proven to reduce the need for allogeneic blood transfusion in elective THA patients. Data regarding TXA efficacy in reducing blood loss in trauma patients undergoing non-elective primary THA is sparse, and its routine use is not well established.MethodsThis is a retrospective analysis of a consecutive cohort of patients who underwent non-elective primary THA in a tertiary medical center between January 1st 2011- December 31st 2019. The cohort was divided into two groups; one received perioperative TXA treatment while the other did not. Blood loss, blood product administration, peri and postoperative complications, readmissions and 1-year mortality were compared between groups.ResultsA total of 419 patients (146 males, 273 females) who underwent THA were included in this study. The "TXA" group consisted 315 patients compared to 104 patients in the "no TXA" group. TXA use reduced postoperative bleeding, as indicated by changes in hemoglobin levels before and after surgery (ΔHb= -2.75 gr/dL vs. ΔHb= -3.34 gr/dL, p<0.001) and by administration of allogeneic blood transfusions (7.0% vs. 16.3%, p = 0.004).ConclusionSimilar to the known effect of TXA in elective THA patients, the use of TXA treatment in patients undergoing non-elective THA led to a significant reduction in postoperative blood loss and in the proportion of patients requiring allogeneic blood transfusions.  相似文献

Background

Routine laboratory studies are often obtained following total hip arthroplasty (THA). Moreover, laboratory studies are often continued daily until the patient is discharged regardless of medical management. The purpose of this study was to investigate the use of routine complete blood count (CBC) tests following THA. Secondarily, the purpose was to identify patient factors associated with abnormal postoperative lab values.

Methods

This retrospective review identified 352 patients who underwent primary THA at a single institution from 2012 to 2014. Preoperative and postoperative CBC values were collected along with demographic data, use of tranexamic acid (TXA), and transfusion rates. Logistic regression models were used to identify factors associated with an abnormal postoperative lab and risk of transfusion.

Results

Of the 352 patients, 54 patients were transfused (15.3%). Patients who underwent transfusion had a significantly lower preoperative hemoglobin (Hb; 12.0 g/dL) compared to patients who did not undergo transfusion (13.5 g/dL; P < .001). Patients who did not receive TXA were 3.7 times more likely to receive a transfusion. No patients received medical intervention based on the outcome of postoperative platelet or white blood counts. A Hb value below 11.94 g/dL for patients who are anemic preoperative or did not receive TXA predicted transfusion after postoperative day 1.

Conclusion

Under value-based care models, cost containment while maintaining high-quality patient care is critical. Routine postoperative CBC tests in patients with a normal preoperative Hb who receive TXA do not contribute to actionable information. Patients who are anemic before THA or do not receive TXA should at minimum obtain a CBC on postoperative day 1.  相似文献

Background

Total hip and knee arthroplasty (THA and TKA) are associated with significant blood loss and some patients require postoperative blood transfusion. While tranexamic acid has been studied extensively among this population, we tested the hypothesis that epsilon aminocaproic acid (EACA) can reduce blood loss and transfusion after joint arthroplasty.

Methods

In April 2014, our Veterans Affairs Medical Center introduced a protocol to administer EACA during THA and TKA. No antifibrinolytics were used previously. We retrospectively compared blood loss and incidence of transfusion among patients who underwent primary arthroplasty in the year before standardized administration of EACA with patients having the same procedures the following year. Blood loss was measured as delta hemoglobin (preoperative hemoglobin ? hemoglobin on postoperative day 1). All patients undergoing primary THA or TKA were included. Patients having revision surgery were excluded.

Results

We identified 185 primary arthroplasty patients from the year before and 184 from the year after introducing the EACA protocol. There were no changes in surgical technique or attending surgeons during this period. Delta hemoglobin was significantly lower in the EACA group (2.7 ± 0.8 mg/dL) compared to the control group (3.4 ± 1.1 mg/dL) (P < .0001). The incidence of blood transfusion was also significantly lower in the EACA group (2.7%) compared to the control group (25.4%) (P < .0001). There was no difference in venous thromboembolic complications between groups.

Conclusion

We demonstrated reductions in hemoglobin loss and transfusion following introduction of the EACA protocol in patients undergoing primary arthroplasty. EACA offers a lower cost alternative to TXA for reducing blood loss and transfusion in this population.  相似文献
