连续护理干预模式对脊柱骨折伴脊髓损伤患者术后康复效果的研究

目的研究分析连续护理干预模式对脊柱骨折伴脊髓损伤患者术后康复效果。方法本项研究回顾了2017年2月—2018年7月间在某院采取了脊柱骨折伴脊髓损伤治疗的52例患者整个治疗过程的资料,将所有的患者使用数字双盲法将其分为了对照组(n=26)和观察组(n=26)。对照组患者使用护理措施为常规护理措施,观察组使用的护理措施为连续护理干预模式,在患者治疗完成后对比两个不同组别患者在围手术期期间各类指标和出现并发症概率。结果对照组患者手术下床活动时间、住院时间、住院所需费用以及患者并发症发生率均显著高于观察组,组别间数据对比差异具有统计学意义(P<0.05)。结论医护人员在进行脊柱骨折伴脊髓损伤患者的护理工作当中,对其采取连续护理模式可以降低患者并发症发生率,缩短患者住院时间,对患者身体的恢复具有显著意义。     

Características clínicas y pronóstico de la lesión medular traumática en pacientes mayores de 75 años

ObjectiveTo analyze the incidence and characteristics of traumatic spinal cord injury (SCI) in geriatric population of Galicia (Spain), hospital management and functional prognosis.MethodsComparative retrospective study. Patients admitted with acute traumatic SCI during the time period between January 2010 and December 2016 were included. Two groups established: The elderly over and under 75 years of age, with the latter acting as a control group.ResultsThree hundred seventy-nine patients were studied (27.2% ≥75 years). The main etiology in the >75 years group were falls: 80.6%. There were 65.7% who presented incomplete spinal cord injuries with mean motor index (MI) of 44.9/100. Upon discharge, 90.8% were dependent. Hospital mortality was 34.9%. Those >75 years suffered from more cervical injuries (74.8 vs. 51.2%; p<0.001), longer delay in diagnosis (31.1 vs. 9.2%; p<0.001) and higher hospital mortality (34.9 vs. 3.2%; p<0.001). Fewer surgical interventions were performed, with a longer delay. Percentages for admission into ICU, mechanical ventilation and performing a tracheostomy proved to be similar. There were no significant differences found in the evolution according to the ASIA scale or the MI.Conclusions1) The frequency of traumatic SCI in the elderly in Galicia is high; 2) Neurological evolution is similar to younger patients but the level of dependence is higher; 3) The level of care provided is similar in both groups, except for the surgical indication, and 4) Hospital mortality is high.     

Measured and predicted resting energy expenditure in wheelchair rugby athletes

Objective: Report measured resting energy expenditure (REE) in wheelchair rugby athletes and evaluate agreement between REE and the prediction models of Chun, Cunningham, Harris-Benedict, Mifflin, Nightingale and Gorgey, and Owen.

Design: Cohort-based validation study.

Setting. Paralympic team training camp.

Participants: Fourteen internationally competitive athletes who play wheelchair rugby, 13 of whom had cervical spinal cord injuries (SCI).

Outcome Measures: A portable metabolic analyzer was used to measure REE following an overnight fast and dual-energy X-ray absorptiometry (DXA) was used to assess lean body mass for the prediction equations.

Results: REE in the current sample was 1735?±?257?kcal?×?day^?1 ranging from 1324 to 2068?kcal?×?day^{?1 Bhambhani Y. Physiology of wheelchair racing in athletes with spinal cord injury. Sports Med 2002;32(1):23–51.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]}. Bland–Altman analyses revealed negative mean bias but similar limits of agreement between measured REE and scores predicted by Chun, Cunningham, Mifflin, Nightingale and Gorgey, and Owen models in elite athletes who play wheelchair rugby.

Conclusion: Prediction models regressed on persons with and without SCI under-predicted REE of competitive wheelchair rugby athletes. This outcome may be explained by the higher REE/fat-free mass (FFM) ratio of current athletes compared to less active samples. Findings from the current study will help practitioners to determine nutrient intake needs on training days of varied intensity.     

黄连解毒汤对重度颅脑损伤合并肺部感染患者血气指标和炎症因子影响分析

目的:观察黄连解毒汤对重度颅脑损伤合并肺部感染患者血气指标和炎症因子的影响,探讨其治疗效果。方法:随机抽签方式将77例重度颅脑损伤合并肺部感染患者分为两组。对照组35例接受常规治疗,研究组42例在常规治疗基础上,联合黄连解毒汤直肠灌注及全身擦浴治疗。评估两组临床效果,记录两组呼吸机使用时间、ICU入住时间及治疗费用,测定两组治疗前后血气指标和炎症因子。结果:两组临床治疗效果间差异无统计学意义(P>0.05)。与对照组比,研究组呼吸机使用时间和ICU入住时间明显缩短,ICU治疗费用显著减少(P<0.01)。治疗后两组SaO、PaO₂水平明显上升,PaCO₂及血清PCT、IL-1β、HMGB-1、CRP水平明显下降(P<0.05)。组间比较,研究组SaO、PaO₂水平高于对照组,PaCO₂及血清PCT、IL-1β、HMGB-1、CRP水平低于对照组(P<0.05)。结论:黄连解毒汤直肠灌注联合全身擦浴可明显控制重度颅脑损伤合并肺部感染患者感染病症,改善血气指标,调节炎症反应,缩短呼吸机使用时间和ICU入住时间,减少患者的治疗费用。     

冠状病毒感染对心血管系统的损伤及可能机制

冠状病毒(coronavirus,CoVs)感染主要累及肺部,但对心血管系统损伤作用也不容忽视。CoVs感染引起的心脏损伤并非罕见,其发生与病情的严重程度密切相关。本文首先从CoVs引起心血管损伤的证据入手,进一步探讨了CoVs对心肌的直接损伤,以及肾素血管紧张素(RAS)系统激活和细胞因子风暴与炎症反应对心血管损伤的可能作用机制。相关心血管损伤的可能机制包括,(1)病毒直接作用:CoVs在心肌细胞复制,损伤心肌;(2)RAS系统激活:感染CoVs后,心脏血管紧张素转化酶2(angiotensin-converting enzyme 2,ACE2)的表达下调,激活RAS系统,使得血管紧张素Ⅱ(AngiotensinⅡ,AngⅡ)收缩血管功能增强,Ang1-7保护心脏效应减弱;(3)诱发细胞因子风暴:循环细胞因子和全身炎症反应引起心脏损伤;(4)其他:包括低氧血症和儿茶酚胺心脏毒性。本文就相关内容作一综述,为后续的详尽机制和治疗策略研究提供思路。     

Validity and reliability of the Turkish version of the pressure injury knowledge assessment tool 2.0

AimThe aim of this study was to develop a Turkish version of the Pressure Ulcer Knowledge Assessment Tool 2.0 (PUKAT 2.0) and determine its validity and reliability.Materials and MethodsThis was a cross-cultural adaptation and validation study. The study sample included a total of 451 participants (232 nurses and 219 nursing students). The validity of the Turkish version of the PUKAT 2.0 was evaluated with linguistic validity, content validity, item validity (item difficulty, discriminating index), and construct validity (known-groups technique) analyses. The reliability of the tool was evaluated by conducting a test–retest analysis.ResultsContent validity index (CVI) for the items (Item-CVI) ranged from 0.83 to 1.00 and the CVI for the scale (Scale-CVI) was 0.95. The difficulty index for 21 items ranged from 0.10 to 0.63. Four items were found to be too difficult. Item discriminating index values ranged from 0.00 to 0.61. The overall intraclass correlation coefficient (ICC) was found to be 0.80.ConclusionThe Turkish version of the Pressure Injury Knowledge Assessment Tool 2.0 (PIKAT 2.0-Tr) is supported by acceptable psychometric properties and can be used to evaluate the knowledge of nurses and nursing students in Turkey about the prevention of PI.     

Influence of luminal stenosis in aneurysmal and non-aneurysmal blunt cerebrovascular injury

Background

Current blunt cerebrovascular injury (BCVI) grading grossly differentiates injury characteristics such as luminal stenosis (LS) and aneurysmal disease. The effect of increasing degree of LS beyond the current BCVI grading scale on stroke formation is unknown.
