Manejo anestésico de las pacientes embarazadas tetrapléjicas durante el parto: una revisión sistemática

IntroductionPregnancy in spinal cord injured patients has specific issues that must be carefully addressed. However, guidelines for their management are scarce.MethodsA systematic review of the literature regarding the anaesthetic management during delivery of pregnant patients with cervical spinal cord injury was performed on the electronic databases of PubMed (Medline) and Cochrane.ResultsA higher incidence of preterm birth and caesarean delivery were seen. Anaesthetic management was diverse, although most pregnant patients received epidural analgesia. Autonomic dysreflexia symptoms were present in 51% of pregnancies.ConclusionTimely management of these patients could possibly reduce caesarean and preterm delivery rates, avoid or minimize common complications, as well as reduce costs. An early reference to anaesthesiology consultation and a multidisciplinary approach is recommended.

Management of blood pressure disorders in individuals with spinal cord injury

Blood pressure regulation is impacted by a spinal cord injury (SCI) due to impaired descending sympathetic vascular control. Common blood pressure problems in the SCI population include persistently low blood pressure with bouts of orthostatic hypotension and autonomic dysreflexia, which are more prevalent in individuals with lesions above the sixth thoracic vertebral level; however, they may occur regardless of the neurological level of injury. Although blood pressure disorders adversely impact daily function and quality of life, most individuals with SCI do not acknowledge this association. Few pharmacological options have been rigorously tested for safety and efficacy to manage blood pressure disorders in the SCI population. Furthermore, clinical management of any one blood pressure disorder may adversely impact others, as such treatment is complicated and not often prioritized.     

两种保留自主神经D3根治术治疗中低位直肠癌的安全性及生存质量比较

目的比较腹腔镜保留自主神经D3根治术与开腹术治疗中低位直肠癌的安全性及生存质量差异。 方法回顾性分析2015年6月至2017年8月间84例低位直肠癌患者资料，根据手术方式不同分为腹腔镜组(n＝46)和开腹组(n＝38)，应用SPSS21.0软件完成数据分析。手术相关指标采用( ±s)表示，独立样本t检验；并发症发生率、复发率及生存率等指标采用χ²检验；P<0.05为差异有统计学意义。 结果腹腔镜组患者的手术时间长于开腹组(P<0.05)，而术中出血量、住院时间、尿管保留时间、肛门排气时间均短于开腹组(均P<0.05)。腹腔镜组术后并发症总发生率为6.5%低于开腹组的26.3%(χ²＝4.6517，P<0.05)。两组患者1年局部复发率及生存率差异均无统计学意义(均P>0.05)。腹腔镜组患者术后10 d排尿功能、术后2个月勃起功能、术后2个月射精功能均优于开腹组(均P<0.05)。 结论腹腔镜保留自主神经D3根治术治疗中低位直肠癌安全性较高，复发率及生存率与开腹术相当，并能显著提高患者的生存质量，值得推广应用。     

瓦氏动作在脑血流自动调节功能中的应用

CA是指脑血流在动脉血压和脑灌注压发生改变时保持相对稳定的一个复杂的多因素过 程。脑血流自动调节与多种神经系统疾病如脑血管病、帕金森病、头痛、自主神经功能障碍等疾病的 发生、发展及临床预后相关。对脑血流自动调节功能有很多种评估测量方法，监测瓦氏动作所诱导 的血压变化更具有操作性及标准化，适用于各种人群，其安全、简单、准确的特点使其在脑血流自动 调节中运用十分广泛。本文重点对瓦氏动作在脑血流自动调节功能中的应用做一个综述介绍。     

脑小血管病排尿与排便障碍研究现状及机制探索

脑小血管病（cerebral small vessel disease，CSVD）是一种主要累及脑内小血管的慢性全脑性 疾病，临床表现多样。排尿障碍和排便障碍作为CSVD的常见症状，严重影响着人们的日常生活和社 会功能。约70%的CSVD患者可出现排尿障碍，以排尿刺激症状为主，可表现为尿频、尿急、急迫性尿 失禁及夜尿增多，且与疾病的严重程度、病变部位相关。排便障碍与脑血管病关系密切，但目前尚无 有关CSVD患者排便障碍的大型流行病学数据。本文分别以CSVD患者排尿功能障碍与排便功能障碍 为切入点，探讨CSVD患者二便障碍的发生率和具体表现形式，探索可能引起CSVD患者二便障碍的病 理生理机制，为CSVD的诊治提供新的方向。     

关于医学硕士研究生科研写作能力的培养思考

随着国家社会经济的高速发展,各领域都需要更多高层次拔尖创新性人才。我国医药卫生事业的快速、稳定发展将会直接关系国民生命的健康,这就需要培养大量硕士研究生及以上的医学高层次人才。目前,医学硕士研究生还存在着科研能力不足的现状,而科研写作是科研水平和科研质量的呈现,是增强沟通、提高创新性的必然媒介。就如何培养提高医学硕士研究生写作能力内外部影响因素进行了阐述,并提出了改善方法。     

Transient anisocoria after a traumatic cervical spinal cord injury: A case report

Context: Autonomic dysreflexia and dysautonomia can be a common complication following spinal cord injury, especially at levels of T6 and above and can lead to complications associated with the pupil. In this case report, we review autonomic dysreflexia, the anatomy and physiology of the sympathetic nervous system of the eye, as well as review the clinical relevance in understanding autonomic and pupillary changes in response to autonomic dysfunction.

Findings: We present a patient with an incomplete C4 level injury who was found to have isolated anisocoria on two separate occasions during his acute inpatient rehabilitation stay.

Conclusion/Clinical Relevance: Anisocoria associated with abnormal sympathetic activation may be a clinical sign of dysautonomia.
