Conservative initial postoperative anticoagulation strategy after HeartMate 3 left ventricular assist device implantation

Introduction

Although anticoagulation therapy is mandated after implantation of a left ventricular assist device (LVAD), postoperative bleedings and reoperations occur relatively frequently and are associated with worse outcomes. We evaluated the use of a conservative postoperative anticoagulation protocol in patients implanted with a HeartMate 3 (HM3) LVAD.

Methods

In a single-centre retrospective analysis of postoperative outcomes after HM3 LVAD implantation, a standard (old) anticoagulation protocol (i.e. early, full-dose anticoagulation with low-molecular weight heparin and overlapping vitamin K antagonist) was compared with a new conservative anticoagulation protocol (i.e. slow initiation of vitamin K antagonists without overlapping heparin). Main outcomes were changes in international normalised ratio (INR), lactate dehydrogenase (LDH), bleeding and/or tamponade events requiring reoperation, length of stay and adverse events.

Results

In total, 73 patients (48 in old vs 25 in new protocol group) were evaluated. Mean age was 56 years (standard deviation 13) and most patients (78%) were males. Changes in INR and LDH in the first 14 days were similar in both groups (p?=?0.50 and p?=?0.997 for interaction, respectively). Number of bleeding/tamponade events requiring reoperation was lower in the new than in the old protocol group (4% vs 33%, p?=?0.005). Postoperative 30-day mortality was similar, and we observed no thromboembolic events. Median (25th–75th percentiles) total length of postoperative hospital stay (27 (25–41) vs 21 (19–27) days, p?<?0.001) and length of intensive care unit stay (5 (2–9) vs 2 (2–5) days, p?=?0.022) were significantly shorter in the new protocol group.

Conclusion

These retrospective data suggest that conservative slow initiation of anticoagulation therapy after HM3 LVAD implantation is associated with less bleeding/tamponade events requiring reoperation, a similar safety profile and a shorter duration of stay than the currently advised standard anticoagulation protocol.

     

神经内镜与显微镜下经鼻蝶入路手术切除垂体腺瘤的临床疗效比较及术中出现脑脊液漏的危险因素分析

摘要 目的：对比垂体腺瘤患者采用显微镜或神经内镜下经鼻蝶入路手术切除后的临床疗效,分析术中出现脑脊液漏的危险因素。方法：回顾性分析2018年3月~2022年2月期间来我院接受手术治疗的178例垂体腺瘤患者的临床资料。根据采用手术器械的不同将178例患者分为A组（显微镜,n=91）和B组（神经内镜,n=87）。比较两组的肿瘤有效切除率、临床指标、术中脑脊液漏发生率及术后并发症发生率。根据术中是否发生脑脊液漏分为脑脊液漏组和无脑脊液漏组。经单因素和多因素Logistic回归分析患者术中发生脑脊液漏的危险因素。结果：B组的手术时间、住院时间短于A组,术中出血量少于A组（P<0.05）。A组、B组的肿瘤有效切除率组间对比,无统计学差异（P>0.05）。B组术中脑脊液漏发生率、术后并发症发生率低于A组（P<0.05）。垂体腺瘤患者术中发生脑脊液漏与再次手术、肿瘤大小、年龄、肿瘤质地、美国麻醉医师协会（ASA）分级有关（P<0.05）。肿瘤大小为巨大腺瘤、再次手术、肿瘤质地为韧是垂体腺瘤患者术中发生脑脊液漏的危险因素（P<0.05）。结论：显微镜与神经内镜下经鼻蝶入路手术切除垂体腺瘤,治疗效果相当,但神经内镜下手术可缩短手术时间、住院时间,减少术中出血量,降低术中脑脊液漏发生率、术后并发症发生率。此外,肿瘤大小为巨大腺瘤、再次手术、肿瘤质地为韧是垂体腺瘤患者术中发生脑脊液漏的危险因素。     

Comparison of ReoPro((R)) (abciximab) versus intracoronary thrombolysis for early coronary stent thrombosis

AIMS: This study evaluated the treatment of early coronary stent thrombosis with intracoronary urokinase or the platelet glycoprotein IIb/IIIa receptor inhibitor ReoPro (abciximab). METHODS AND RESULTS: Seventy-four patients (126 stents) were treated immediately after identification of early (0-30 days) coronary stent thrombosis. Twenty-nine patients were treated with intracoronary urokinase (UK) (UK alone in 19; UK and additional balloon angioplasty in 10) and another 45 patients were given ReoPro((R)) (abciximab) (0.25 mg/kg as a bolus alone in 26, abciximab with additional balloon angioplasty in 19) within 30 days of stent implantation. TIMI grade 3 flow was obtained in 23 patients (79%) in the UK group and in 38 (84%) in the abciximab group (nonsignificant). Three patients (10%) in the UK group and one (2%) in the abciximab group underwent repeat percutaneous transluminal coronary angioplasty (PTCA) (nonsignificant). Five patients (17%) in the UK group and three (7%) in the abciximab group were referred for urgent coronary artery bypass graft surgery (CABG) because of residual thrombus and refractory ischemia (nonsignificant). Repeat revascularization was necessary in eight patients (28%) in the UK group versus four (9%) in the abciximab group (p < 0.05). Five patients (17%) in the UK group and eight (18%) in the abciximab group developed myocardial infarction (nonsignificant). Five patients (17%) in the UK group (cardiogenic shock (three), cerebral hemorrhage (one) and pneumonia (one)) and three (6.6%) in the abciximab group (cardiogenic shock (two), heart failure (one)) died within 30 days (nonsignificant). Overall, noncardiac complications (bleeding including surgical repair of groin) were observed in 11 patients (38%) in the UK group and three (7%) in the abciximab group (p < 0.001). CONCLUSION: Compared to urokinase, abciximab reduced the need for repeat revascularization procedures and the risk of noncardiac events, including bleeding complications in patients with early coronary stent thrombosis.     

Perioperative cardiovascular complications versus perioperative bleeding in consecutive patients with known cardiac disease undergoing non-cardiac surgery. Focus on antithrombotic medication. The PRAGUE-14 registry

Background

Interruption of antithrombotic treatment before surgery may prevent bleeding, but at the price of increasing cardiovascular complications. This prospective study analysed the impact of antithrombotic therapy interruption on outcomes in non-selected surgical patients with known cardiovascular disease (CVD).

Methods

All 1200 consecutive patients (age 74.2 ± 10.2 years) undergoing major non-cardiac surgery (37.4 % acute, 61.4 % elective) during a period of 2.5 years while having at least one CVD were enrolled. Details on medication, bleeding, cardiovascular complications and cause of death were registered.

Results

In-hospital mortality was 3.9 % (versus 0.9 % mortality among 17,740 patients without CVD). Cardiovascular complications occurred in 91 (7.6 %) patients (with 37.4 % case fatality). Perioperative bleeding occurred in 160 (13.3 %) patients and was fatal in 2 (1.2 % case fatality). Multivariate analysis revealed age, preoperative anaemia, history of chronic heart failure, acute surgery and general anaesthesia predictive of cardiovascular complications. For bleeding complications multivariate analysis found warfarin use in the last 3 days, history of hypertension and general anaesthesia as independent predictive factors. Aspirin interruption before surgery was not predictive for either cardiovascular or for bleeding complications.

Conclusions

Perioperative cardiovascular complications in these high-risk elderly all-comer surgical patients with known cardiovascular disease are relatively rare, but once they occur, the case fatality is high. Perioperative bleeding complications are more frequent, but their case fatality is extremely low. Patterns of interruption of chronic aspirin therapy before major non-cardiac surgery are not predictive for perioperative complications (neither cardiovascular, nor bleeding). Simple baseline clinical factors are better predictors of outcomes than antithrombotic drug interruption patterns.     

甲状腺再次手术治疗的临床分析

目的:探讨甲状腺再次手术的原因、手术方式的选择和手术效果以及患者的预后情况。方法:统计哈尔滨医科大学附属第二医院普外科2001年1月到2015年9月期间收治的1600例初次行甲状腺手术的患者,回顾分析其中175例再次行甲状腺手术患者的临床资料。结果:甲状腺再次手术采用双侧甲状腺次全切除术为92例,单侧甲状腺次全切除术为72例,甲状腺癌根治术为11例。甲状腺再次手术患者术后出现甲状腺功能减退、气管和喉返神经损伤、出血以及缺钙引起的手足抽搦等概率高,与首次手术比较差异有统计学意义(P0.05)。术后1年内对再次手术的患者进行随访,其中复发12例(病理确诊为甲状腺癌3例,结节性甲状腺肿9例),其他类型甲状腺疾病无复发。结论:甲状腺再次手术较初次手术难度较大,术中及术后并发症较多,再次手术应谨慎选择术式及术中精细操作。     

Effects of Glycemia on Immediate Complications Followings Cabg

ObjectiveWe investigated the relationship between postoperative glucose levels (days 1 through 3) and immediate outcomes in patients who underwent isolated coronary artery bypass grafting (CABG).MethodsWe conducted a retrospective study of 2,558 consecutive patients who had isolated CABG. Patients were stratified into 3 groups based on their pre-operative mortality risk (MR), using Society of Thoracic Surgeons’ criteria. Average glucose levels for the first 3 days following surgery were determined. Glucose levels for each group were divided into quartiles and related to relevant outcomes. Odds ratios assessing changes in outcomes as functions of increased glucose exposure were determined for postoperative days 1, 2, and 3 and for postoperative days 1 and 2 and 1 through 3.ResultsThe number of patients in each MR group (1 through 3; low, medium, and high) was 1,233, 852, and 473, respectively. Mean ± SD quartile glucose levels for days 1 and 2 were 133 ± 8.2, 150.4 ± 4.7, 167.2 ± 6.89, and 205.9 ± 24.9 mg/dL. The proportion of patients with a glucose level <70 mg/dL was 6.4%, <60 mg/dL was 2.7%, and <50 mg/dL was 1.1%.The most consistent and significant correlations between glucose quartiles and outcomes were observed for MR group 1, and they were most significant for the first 2 days following surgery. Glycemic control was not correlated with mortality, but it was correlated with total complications.ConclusionHyperglycemia during the first two days after CABG adversely affected total complications in patients who were in the low and medium MR groups, but it did not significantly affect hospital mortality.

用降钙素原和白细胞联合能预测心脏手术病人的感染

为了探讨通过结合C反应蛋白(C-reactive protein, CRP)、白细胞(leukocyte, WBC)和降钙素原(procalcitonin, PCT)来预测大批心脏病手术患者术后感染的可行性,本研究病例对照研究涉及423例接受心肺心脏搭桥手术的心脏病患者。基于在术后期间是否有严重的败血症或化脓性休克,病人被分成两组。在重症监护病房的第1天,提取用于生物测量(PCT, CRP和WBC)的血液样本,然后每天早上提取1次,直到术后第10天。研究发现,两组群体的CRP中值类似。在10 d术后期间,感染病人群体中的WBC和PCT中值明显比未感染的群体高。高程截止≤3次(概率:4.058, 95%置信区间:2.206～7.463; p=0.001)和高程截止≥4次(概率:10.274, 95%置信区间:3.690～28.604; p<0.001),在术后第2天,随着感染的发展,PCT中值(1.7 ng/mL)和/或WBC中值(13 000个细胞/mm3)发生了明显的变化。本研究初步表明,在术后前3 d,PCT和WBC水平结合,能够预测接下来30 d心脏手术的术后感染情况,具有一定的临床应用价值。     

Gastric Bypass in a Low‐Income,Inner‐City Population: Eating Disturbances and Weight Loss

Objective: To examine the prevalence of eating disturbances and psychiatric disorders among extremely obese patients before and after gastric bypass surgery and to examine the relationship between these disturbances and weight outcomes. Research Methods and Procedures: Sixty‐five women patients (ages 19 to 67) with a mean BMI of 54.1 were assessed by semistructured psychiatric interview before surgery and by telephone interview after surgery (mean follow‐up: 16.4 months) to determine psychiatric status, eating disturbances, and weight and health‐related variables. Results: Patients lost a mean of 71% of their excess BMI, with significantly poorer weight loss outcomes among African Americans. Psychiatric disorders remained prevalent before (37%) and after (41%) surgery. In contrast, binge eating disorder dropped from 48% to 0%. Psychiatric diagnosis did not affect weight outcomes. Instead, more frequent preoperative binge eating, along with greater initial BMI, follow‐up length, and postoperative exercise, predicted greater BMI loss. Postsurgical health behaviors (exercise and smoking) and nocturnal eating episodes were also linked to weight loss. Exercise frequency increased and smoking frequency tended to decrease after surgery. Discussion: These findings indicated that eating and psychiatric disturbances did not inhibit weight loss after gastric bypass and should not contraindicate surgery. Prior binge eating, eliminated after surgery, predicted BMI loss and, thus, may have previously been a maintaining factor in the obesity of these patients. The association between health behaviors and outcome suggests possible targets for intervention to improve surgical results. Poorer outcomes among African Americans indicate that these patients should be closely monitored and supported after surgery.

A 10-year review of perioperative complications in pharyngeal flap surgery

A 10-year retrospective study was undertaken to investigate perioperative complications in pharyngeal flap surgery in one institution using inferiorly and superiorly based flaps. In this fashion the current practice of surgical technique based on local findings and perioperative care, through regular monitoring by experienced nurses on the ward, was evaluated for adequacy. The charts of 275 patients who had 287 pharyngeal flap procedures were studied. Demographics, type and duration of operation, associated procedures, surgeon, anesthetist, duration of hospital stay, associated medical conditions, and perioperative complications such as bleeding, respiratory insufficiency, or flap dehiscence were evaluated. In this series a total complication rate of 6 percent was found, with 2.4 percent early (<6 weeks) and 3.8 percent late (>6 weeks) complications. Only two patients (0.7 percent) had postoperative bleeding requiring reoperation, and one patient (0.3 percent) needed reintubation. The most frequent complication was flap dehiscence in nine patients (3.1 percent), which occurred early in three and late in six. Pharyngeal flap surgery can be performed safely with very few complications provided the correct experience and infrastructure are present. Careful surgery, in conjunction with adequate anesthesia and postoperative monitoring, makes these procedures safe and rewarding.     

Outcome Of Implementation Of A Multidisciplinary Team Approach To The Care Of Patients After Transsphenoidal Surgery

Objective: Transsphenoidal surgery (TS) for sellar lesions is an established and safe procedure, but complications can occur, particularly involving the neuroendocrine system. We hypothesized that postoperative care of TS patients would be optimized when performed by a coordinated team including a pituitary neurosurgeon, endocrinologists, and a specialty nurse.Methods: We implemented a formalized, multidisciplinary team approach and standardized postoperative protocols for the care of adult patients undergoing TS by a single surgeon (J.N.B.) at our institution beginning in July 2009. We retrospectively compared the outcomes of 214 consecutive TS-treated cases: 113 cases prior to and 101 following the initiation of the team approach and protocol implementation. Outcomes assessed included the incidence of neurosurgical and endocrine complications, length of stay (LOS), and rates of hospital readmission and unscheduled clinical visits.Results: The median LOS decreased from 3 days preteam to 2 days postteam (P<.01). Discharge occurred on postoperative day 2 in 46% of the preteam group patients compared to 69% of the postteam group (P<.01). Rates of early postoperative diabetes insipidus (DI) and readmissions within 30 days for syndrome of inappropriate antidiuretic hormone (SIADH) or other complications did not differ between groups.Conclusion: Implementation of a multidisciplinary team approach was associated with a reduction of LOS. Despite earlier discharge, postoperative outcomes were not compromised. The endocrinologist is central to the success of this team approach, which could be successfully applied to care of patients undergoing TS, as well as other types of endocrine surgery at other centers.Abbreviations:CSF = cerebrospinal fluidDDAVP = desmopressinDI = diabetes insipidusLOS = length of stayPOD = postoperative daySIADH = syndrome of inappropriate antidiuretic hormoneTS = transsphenoidal surgery     

Bloodless open heart surgery with atraumatic extracorporeal circulation.

With careful refinements in the pump oxygenator and a nonblood prime, bloodless open heart surgery may be performed almost routinely. In our series these measures reduced blood trauma, with a remarkable preservation of blood elements, especially platelets, and a corresponding elimination of postoperative bleeding. The mean hematocrit value decreased from 38 to 27% and recovered to 33% in the first 3 hours of postoperative diuresis. Mannitol and furosemide were rarely needed. Of 61 adult patients whp underwent open heart surgery for aortocoronary bypass or valve replacement, the last 43 had a bloodless procedure. Of the 43, 26 (60%) required no bank blood postoperatively (in the operating room or the intensive care unit). In these 26 the operative mortality was 4% (1 patient). Bloodless techniques are invaluable during periods of bank blood shortage. They avoid the dangers of hepatitis and transfusion reaction, and they may minimize the incidence of postperfusion lung syndrome as well as renal complications.

Peritoneal cytokines as early markers of peritonitis following surgery for colorectal carcinoma: a prospective study

This study was to investigate if measurement of peritoneal cytokines is valuable for an early diagnosis of peritonitis following colorectal surgery. One hundred consecutive patients who were to undergo elective resection for carcinoma of the sigmoid colon or the rectum were investigated. Abdominal exudate was obtained from a drainage tube daily after surgery for measuring interleukin (IL)-1β, IL-6 and tumour necrosis factor (TNF)-α. The relationship between peritoneal cytokine levels during the first 3 days after surgery and the development of peritonitis was investigated. Eight patients developed postoperative peritonitis due to anastomotic leakage and pelvic abscess, which was diagnosed on postoperative days 5-8. Peritoneal cytokine levels on postoperative days 1 and 2 were not significantly different between the 8 patients who developed peritonitis and 92 patients who did not: day 1, IL-1βP=0.32, IL-6 P=0.45, TNF-αP=0.85; day 2, IL-1βP=0.26, IL-6 P=0.68, TNF-αP=0.22. In contrast, the cytokine levels on day 3 were significantly higher in patients who developed peritonitis as compared with patients who did not: IL-1βP=0.008, IL-6 P<0.0001, TNF-αP=0.0001. The cytokines significantly increased during the first 3 days in patients who developed peritonitis: IL-1βP=0.049, IL-6 P=0.03, TNF-αP=0.01, while significantly decreased in patients who did not: IL-1βP<0.0001, IL-6 P<0.0001, TNF-αP<0.0001. The outcomes of this investigation showed that the rise in peritoneal IL-1β, IL-6 and TNF-α levels may be an additional early diagnostic predictor of intraabdominal complications following colorectal surgery.     

E-PASS评分系统用于评估老龄患者消化道手术后并发症和转归的临床价值研究

目的:评价日常活动和手术应激评估(Estimation of physiologic ability and surgical stress,E-PASS)系统用于评估老龄患者消化道手术后并发症和转归的临床价值。方法:回顾性分析2011年7月至2013年7月西京医院消化外科所有65岁以上的患者的临床资料,计算其中行消化道手术者的E-PASS评分,并记录这些患者术后并发症的发生情况和患者术后的住院时间。分析E-PASS评分和几项该评分未涉及的因素与老龄患者消化道手术后并发症的发病率、死亡率、住院时间的相关性。结果:研究共纳入1236例老龄行消化道手术的患者,其中521例发生术后并发症(42.15%),8例死亡(0.65%)。患者术前E-PASS评分系统中,三项评分均与术后住院时间相关,术前风险评分(Preoperative risk score,PRS)和综合风险评分(Comprehensive risk score,CRS)与术后并发症的发病率和死亡率显著相关(P均0.05)。E-PASS评分系统未包含的指标中,麻醉方法与术后并发症发生和住院时间无关,术后入ICU、术中使用血管活性药物和急诊手术与术后发病率、死亡率和住院时间相关(P均0.05)。结论:E-PASS评分系统可用于预测老龄患者行消化道手术后并发症的发生情况和转归,纳入术后入ICU、术中使用血管活性药物和急诊手术三项指标可能进一步提高E-PASS评分系统的预测准确性。     

Survival Impact of Delaying Postoperative Radiotherapy in Patients with Esophageal Cancer

The purpose of the current study was to retrospectively assess the effect of postoperative radiotherapy (RT) delay on survival for patients with esophageal cancer. From 2008 to 2011, patients with esophageal cancer who had undergone postoperative RT in five different hospitals in China were reviewed. Clinical data, including time interval between surgery to RT, were prospectively collected. Kaplan-Meier method was conducted to estimate the effect of each variable on progression-free survival (PFS) and overall survival (OS), with differences assessed by log-rank test. Univariate Cox proportional-hazards models were performed for both PFS and OS for all assumed predictor variables. Statistically significant predictor variables (P < .05) on univariate analysis were then included in multivariate Cox proportional-hazards models, which were performed to compare the effects of RT delay on PFS and OS. A total of 316 patients were finally enrolled in this prospectively multicentric study. Time to RT after surgery varied from 12 days to over 60 days (median, 26 days). Multivariate analysis showed that delay to RT longer than the median does not appear to be a survival cost. There was also no statistically difference in PFS (P = .513) or OS (P = .236) between patients stratified by quartiles (≤21 days vs ≧35 days). However, patients with particularly long delays (≧42 days) demonstrated a detrimental impact on OS (P = .021) but not PFS (P = .580). Delaying postoperative RT of esophageal cancer does not impact PFS, but results in a significant reduction on OS if delaying longer than 6 weeks.
