OBJECTIVE:The utility of preoperative biomarkers for assessing perioperative complications in patients undergoing spine surgery (SS) is unclear, and no study has assessed the ability of preoperative natriuretic peptides to predict adverse events following SS. This study aimed to evaluate the prognostic importance of N-terminal pro-brain natriuretic peptide (NT-proBNP) in patients undergoing SS. METHODS:We prospectively followed 154 consecutive adult patients ≥50 years old hospitalized for elective SS. The outcomes of interest were length of stay in hospital and perioperative medical complications during hospitalization, defined as pneumonia, deep or organ space surgical site infection, bacteremia, prolonged mechanical ventilation >48 hours, unplanned reintubation, acute renal failure, sepsis or septic shock, venous thromboembolism (deep vein thrombosis or pulmonary embolism), cardiac arrest, stroke, myocardial infarction, return to operating room, and in-hospital mortality. RESULTS:In 21 (13.6%) patients, 32 episodes of medical adverse events occurred. Older patients and patients with more comorbid conditions, such as heart failure, diabetes, cerebrovascular disease, coronary artery disease, and chronic obstructive pulmonary disease, tended to have a higher rate of adverse events. Patients with adverse events had higher NT-proBNP and troponin levels on admission compared with patients without adverse events. Multivariate analysis showed that NT-proBNP >242 pg/ml (odds ratio 2.374; 95% confidence interval, 1.000-2.958; P = 0.001) and presence of diabetes (odds ratio 2.16; 95% confidence interval, 1.86-7.89; P = 0.008) were significant and independent predictors of perioperative adverse events. CONCLUSIONS:This study demonstrates that preoperative NT-proBNP level in patients undergoing SS could be a valuable prognostic marker for several postoperative complications.


目的: 术前生物标志物用于评估脊柱手术 (SS) 患者围手术期并发症的效用尚不清楚,也没有研究评估术前利钠肽预测SS术后不良事件的能力。本研究旨在评估N末端脑钠肽前体 (NT-proBNP) 在SS患者中的预后重要性。 方法: 我们前瞻性随访了 154 例连续的 ≥ 50 岁住院择期SS的成人患者。感兴趣的结果是住院时间和住院期间围手术期医疗并发症,定义为肺炎、深部或器官间隙手术部位感染、菌血症、延长机械通气> 48 小时,非计划再插管率、急性肾衰竭、脓毒症休克,静脉血栓栓塞症 (深静脉血栓形成或肺栓塞),心脏骤停、中风、心肌梗死、返回手术室和住院死亡率。 结果: 在 21 例 (13.6%) 患者中,发生了 32 次医疗不良事件。老年患者和合并疾病较多的患者,如心力衰竭、糖尿病、脑血管疾病、冠状动脉疾病和慢性阻塞性肺疾病,往往有较高的不良事件发生率。有不良事件的患者在入院时NT-proBNP和肌钙蛋白水平高于无不良事件的患者。多因素分析显示,NT-proBNP >242 pg/ml (比值比 2.374; 95% 置信区间,1.000-2.958; P = 0.001) 和存在糖尿病 (比值比 2.16; 95% 置信区间,1.86-7.89; P = 0.008) 是围手术期不良事件的显著和独立预测因素。 结论: 本研究表明,术前NT-proBNP水平在接受SS的患者中可能是一些术后并发症的有价值的预后指标。

METHODS:BACKGROUND:Postoperative cognitive dysfunction (POCD) is a common complication after orthopedic surgery, which is not conducive to the prognosis of the elderly. AIMS:We performed this study to investigate the effects of oxycodone applied for patient-controlled intravenous analgesia (PCIA) on postoperative cognitive function in elderly patients after total hip arthroplasty (THA). METHODS:Ninety-nine participants were enrolled and allocated into two groups: oxycodone group (group O) and sufentanil group (group S). The primary outcome was the incidence of POCD, diagnosed according to the changes in the Mini-mental status examination (MMSE) and Montreal Cognitive Assessment (MoCA) scores. The secondary outcomes included the plasma levels of S-100B protein and neuron-specific enolase (NSE), the amount of postoperative analgesic consumption and the incidence of adverse reactions. RESULTS:The incidence of POCD was significantly lower in patients receiving oxycodone up to the 3rd postoperative day (POD, 1st POD 27.3% vs. 51.1%, P = 0.021; 3rd POD 20.5% vs. 40.0%, P = 0.045), as compared to patients receiving sufentanil. The MMSE and MoCA scores of both groups decreased to varying degrees. However, compared with group S, the MMSE scores at 1st POD, 3rd POD, 5th POD and 7st POD in group O were higher than that in group S, while MoCA scores at 1st POD, 3rd POD and 5th POD in group O were higher. Compared with group S, the plasma levels of S-100B protein in group O at 4 h, 8 h, 12 h post-surgery were lower. While the plasma levels of NSE in group O at 4 h, 8 h, 12 h, 24 h post-surgery were lower. Number of PCIA boluses and consumption of analgesic drug during the first two POD were similar between two groups. However, postoperative incidence of nausea, vomiting and pruritus was significantly lower in patients receiving oxycodone. CONCLUSION:Oxycodone applied for PCIA in elderly patients after THA could reduce the incidence of POCD, improve postoperative cognitive function and decrease the adverse reactions.

METHODS:BACKGROUND:Primary treatment for Blount disease has changed in the last decade from osteotomies or staples to tension band plate (TBP)-guided hemiepiphysiodesis. However, implant-related issues have been frequently reported with Blount cases. The purpose of our study is to evaluate the surgical failure rates of TBP in Blount disease and characterize predictors for failure. METHODS:We performed an Institutional Review Board-approved retrospective chart-review of pediatric patients with Blount disease to evaluate the results of TBP from 2008 to 2017 and a systematic literature review. Blount cases defined as pathologic tibia-vara with HKA (hip-knee-ankle) axis and MDA (metaphyseal-diaphyseal angle) deviations ≥11 degrees were included in the analysis. Surgical failure was categorized as mechanical and functional failure. We studied both patient and implant-related characteristics and compared our results with a systematic review. RESULTS:In 61 limbs of 40 patients with mean follow-up of 38 months, we found 41% (25/61) overall surgical failure rate and 11% (7/61) mechanical failure rate corresponding to 11% to 100% (range) and 0% to 50% (range) in 8 other studies. Statistical comparison between our surgical failure and nonfailure groups showed significant differences in deformity (P=0.001), plate material (P=0.042), and obesity (P=0.044) in univariate analysis. The odds of surgical failure increased by 1.2 times with severe deformity and 5.9 times with titanium TBP in the multivariate analysis after individual risk-factor adjustment. All 7 mechanical failures involved breakage of cannulated screws on the metaphyseal side. CONCLUSIONS:Most of the studies have reported high failure rates of TBP in Blount cases. Besides patient-related risk factors like obesity and deformity, titanium TBP seems to be an independent risk factor for failure. Solid screws were protective for mechanical failure, but not for functional failure. In conclusion, efficacy of TBP still needs to be proven in Blount disease and implant design may warrant reassessment. LEVEL OF EVIDENCE:Level III-retrospective comparative study with a systematic review.

METHODS:INTRODUCTION:As cancer treatments continue to improve the overall survival rates, more patients with a history of cancer will present for anatomic total shoulder arthroplasty (TSA). Therefore, it is essential for orthopaedic surgeons to understand the differences in care required by this growing subpopulation. Although the current research suggests that good outcomes can be predicted when appropriately optimized patients with cancer undergo lower extremity total joint arthroplasty, similar studies for TSA are lacking. The primary study question was to examine whether a history of cancer was associated with an increased rate of venous thromboembolism (VTE) after TSA. Secondarily, we sought to examine any association between a history of prostate and breast cancer and surgical or medical complications after TSA. METHODS:Using a national insurance database, male patients with a history of prostate cancer and female patients with a history of breast cancer undergoing anatomic TSA for primary osteoarthritis were identified and compared with control subjects matched 3:1 based on age, sex, diabetes mellitus, and tobacco use. Patients with a history of VTE and patients who underwent reverse TSA or hemiarthroplasty were excluded. RESULTS:Female patients with a history of breast cancer and male patients with a history of prostate cancer undergoing TSA had significantly higher incidences of acute VTE (including deep venous thrombosis and pulmonary embolism) compared with matched control subjects (female patients: odds ratio, 1.41; 95% confidence interval, 1.10 to 1.81; P = 0.024 and male patients: odds ratio, 1.37; 95% confidence interval, 1.05 to 1.79; P = 0.023). No significant differences were noted in the incidences of any other complications assessed. CONCLUSION:Although a personal history of these malignancies does represent a statistically significant risk factor for acute VTE after anatomic TSA, the overall VTE rate remains modest and acceptable. The rates of other surgical and medical complications are not significantly increased in patients with a history of these cancers after TSA compared with control subjects.
