脊柱后路内固定术后硬膜外血肿的预防与护理体会

目的 探讨脊柱后路内固定术后硬膜外血肿的预防与护理体会。方法 遵照回顾性分析法选择我院2013年2 月～2018 年2 月纳入的60 例脊柱后路内固定术患者，依照不同理疗方式进行分组。其中30 例给予常规药物治疗作为对照组，另30 例除了常规治疗之外实施综合护理作为研究组，记录两组硬膜外血肿、腰椎术后血肿及颈椎术后血肿发生率，分别在干预前后进行生活质量评分（QOL）调查，出院时发放满意度调查问卷表，对比两组干预结果。结果 研究组血肿发生率为6.67%，明显低于对照组的20.00%（P＜0.05）。干预前两组的食欲、精神、睡眠、疼痛及日常生活评分相比差异无统计学意义（P＞0.05），干预后研究组的各项评分均高于对照组（P＜0.05）。研究组对干预效果的满意度为90.00%，明显高于对照组的76.67%（P＜0.05）。结论 护理干预运用于脊柱后路内固定中效果显著，能够有效减少硬膜外血肿的发生率，提升生活质量，促进病情稳定，患者满意度较高，可维持良好医患关系。     

Nerve ultrasound reference data in children from two to seven years

ObjectiveWe examined selected peripheral and spinal nerves of children aged between two and seven years.MethodHigh resolution ultrasound was performed in 116 children (2–7 years of age) at 19 predefined landmarks of median, ulnar, tibial, fibular, sural and radial nerves, the vagus as well as cervical spinal nerve 5 and 6. Further, side-to-side measuring and grey-scale analysis was done at selected nerve sites.ResultsNerves of children were on average smaller than those of adults. Nerve growth correlates significantly with age in all nerves, the mean values were similar in the age of two to four years and five to seven years. Body mass index (BMI) and gender showed moderate effect at some nerve sites, however not uniformly in all. A side-to-side difference of up to 30% in median, and up to 20% in tibial nerve can occur in healthy individuals. Grey-scale analysis for echointensity has been performed in median, ulnar and tibial nerves.ConclusionNerve size increases with age, BMI and gender have moderate effect. A side-to-side-difference of up to 30% can exist.SignificanceReference values of nerve cross-sectional area, side-to-side-difference and echo intensity are necessary to detect nerve pathology in children as well as in adults.     

Angiopathie amyloïde cérébrale ou atteinte des microvaisseaux cérébraux en rapport avec l’HTA : un challenge clinique

Cerebral amyloid angiopathy (CAA) is a entity characterized by degenerative Amyloïd deposits in the walls of the meningeal and cortical vessels. It is considered as the second cause of primitives cerebral hemorrhage in elderly. The differential diagnosis between AAC and hypertension-related cerebral small vessel diseases is difficult and represent a true challenge for the clinician. We report two cases of cerebral small vessel diseases revealed by malignant hypertension.     

重型颅脑损伤的手术治疗

目的探讨重型颅脑损伤梯度减压的手术方法对预防术中脑膨出、降低死亡率及致残率的效果。方法对100例重型颅脑损伤患者采用分次减压手术方式及去骨瓣后，硬膜与颞肌筋膜瓣减张缝闭硬膜切口方法。结果40例脑肿胀患者术中脑嘭出6例占15．0％，死亡19例占47．5％；60例脑内血肿病人未发生脑膨出，死亡12例占20％。结论脑外伤后脑血管调节麻痹及血肿压迫继发脑水肿易造成脑膨出.术中分次减压降低了骨窗部位脑组织的顺应性，从而降低了局部的压力梯度，避免脑血管急性扩张，能有效防止脑膨出，降低死亡率及致残率。     

Hematoma Size in Deep Intracerebral Hemorrhage and its Correlation with Dot-Like Hemosiderin Spots on Gradient Echo T2*-Weighted MRI

BACKGROUND AND PURPOSE: Dot-like low intensity spots (dot-like hemosiderin spots: dotHSs) on gradient echo T2*-weighted MRI have been histologically diagnosed to represent old cerebral microbleeds associated with microangiopathies. They have also been correlated to the fragility of small vessels and the tendency to bleed. Therefore, a substantial number of dotHSs might be associated with a large-sized, deep intracerebral hematoma (ICH). On the other hand, dotHSs may reflect old microbleeds that did not enlarge to symptomatic size. METHODS: To investigate how dotHSs are related to the size (maximal diameter) of primary deep ICH, we analyzed the diameter and the number of dotHSs in 151 patients with deep ICH not associated with subarachnoid hemorrhage or intraventricular hemorrhage (75 males and 76 females, age ranged from 37 to 90 [65.7 +/- 11.3 years old] who were consecutively admitted to Hakodate Municipal Hospital. The hazard ratio (HR) for a maximal diameter of deep ICH < or =2 cm was estimated, using the number of dotHSs and risk factors for stroke. RESULTS: The number of dotHSs associated with the diameter < or =2 cm was 9.2 +/- 11.5, significantly larger than that with the diameter > or =2 cm (4.7 +/- 7.0, P= .012). Multivariate analysis revealed that a maximal diameter of deep ICH of < or =2 cm was found in patients with dotHS (HR, 3.7; 95% confidence interval [CI], 1.4-10.1; P= .009). CONCLUSION: Though small sample size limited the power of our analyses, these findings suggest that the number of dotHSs may be associated with a small diameter of deep ICH.     

创伤性迟发性颅内血肿的诊断和治疗

目的 探讨创伤性、迟发性颅内血肿的早期诊断和治疗的临床效果。方法 对22例病人的发病年龄、性别、伤因、早期诊断和治疗效果进行了回顾性分析。经过2—6个月，按GOS评定治疗效果。结果 良好者12例，中残者5例，重残者1例，植物生存者1例，死亡者3例，死亡率为14％。结论 早期诊断和治疗本病对于提高治愈率和降低死亡率至关重要，早期手术治疗本病，乃是多数病人首选的治疗方法。     

Spinal epidural hematoma. Report of a case and review of the literature

We report the case of a thoracic epidural hematoma at the T7-T9 level which occurred after placement of spinal epidural catheter for continuous anaesthesia in acute pancreatitis. The male patient felt a sudden back pain after six days of successful analgesia and became paraplegic 24 hours afterwards. An emergency laminectomy and removal of the hematoma were performed; however, the patient recovered only incompletely.We discuss the clinical signs and symptoms of spinal epidural hematoma as well as its diagnostics and therapy. The controversial views from the literature concernings its etiology are critically reviewed.     

白介素-6、血管内皮生长因子、D-二聚体对CSDH的影响

目的探讨血肿局部炎症、假膜新血管生成、局部纤溶状况及其在CSDH发生、发展中的作用。进而探讨CSDH的发病机制，并为CSDH的治疗及预防复发提供理论依据。方法以78例CSDH患者作为病例组，20例健康人作为正常对照组。采用ELISA法测定患者血清及血肿液中VEGF及IL-6的含量。比较患者末梢静脉血及血肿液中四种因子的含量变化并与正常对照组比较。结果病例组血肿液FDP、d-dimer检测均为阳性，血液为阴性；正常对照组血液FDP、d-dimer检测均为阴性；病例组血清VEGF含量与正常对照组比较差异无统计学意义。血肿液中VEGF浓度高于血清中。病例组血清IL-6浓度与正常对照组差异无统计学意义，血肿液中IL-6浓度高于血清中。CSDH患者血肿液VEGF、IL-6水平没有相关性。结论CSDH患者血肿液局部纤溶亢进，局部VEGF分泌旺盛，新血管生成活跃，局部炎症活跃，可导致CSDH不断扩大而参与CSDH发病机制。抗炎治疗、抑制VEGF的生理作用、有选择的对病人施行促凝治疗，可成为部分CSDH病人保守治疗及预防复发的有效手段。     

Subakute Verlegung der Atemwege infolge eines retropharyngealen H?matoms nach Halstrauma

Mechanical airway obstruction secondary to retropharyngeal bleeding is rare. In most cases such a complication is described after head and neck trauma. Complicating factors include anticoagulant therapy, tumour, aneurysm, infection or major cervical spine injury. A precise initial diagnosis is necessary to avoid a life-threatening situation. Lateral X-ray and computed tomography is essential for safe management. Treatment depends upon size of the haematoma as well as the clinical course of the patient. Smaller haematomas may be observed. Lager haematomas and those that fail to reabsorb should undergo drainage.
