脑卒中偏瘫患者药熨配合中医推拿的康复护理 总被引:2,自引:0,他引:2
2005年5月-2006年5月收治的66例脑卒中偏瘫患者在神经内科常规治疗的基础上,以药熨配合中医推拿进行康复治疗及护理。药熨法:取吴茱萸50g、莱菔子50g、白芥子50苦、菟丝子50g、苏子50g干燥成熟种子放入小布袋内充分摇匀,放入微波炉内(旁边放1小杯水)用高火加热2-3min,达70~80℃,将药袋放到患肢用力来回推熨;中医推拿:由专业治疗师为患者进行穴位推拿,护士协助其进行坐站走康复练习等。连续施护8周后瘫侧上肢运动功能2级以下7例,2~4级24例,~6级35例;瘫侧下肢运动功能2级以下8例,2~4级12例,~6级46例;治疗后步行能力1级6例,2级15例,3级21例,4级24例。认为在整个康复过程中,康复护理要做好:(1)非活动时瘫痪肢体需功能位摆放;(2)预防和治疗瘫痪肢体痉挛;(3)掌握患者残存机能的范围和程度,以便指导和训练患者进行日常生活活动。药熨时掌握药袋的适宜温度,不可在皮肤病变及破损处行药熨。 相似文献

记录液体出入量(简称出入量)是指将患者24h内的摄人量与排泄量详细地记录在护理记录单上,为临床了解病情,协助诊断,决定治疗方案提供重要依据。因而准确记录出入量是一项十分重要的基础护理工作。由于出入量所包含项目的多样性,在实践中记录出入量容易产生误差,存在着漏记、记量不准确等现象。为进一步分析出入量记录存在误差的原因, 相似文献

Goals of work The objectives of this pilot trial were to assess the potential efficacy and safety of levetiracetam for the treatment of
hot flashes, a major cause of morbidity among breast cancer survivors.
Patients and methods Women, aged 18 years or more, with a history of breast cancer or those who wished to avoid estrogen because of a perceived
increased risk of breast cancer, who were experiencing bothersome hot flashes (more than or equal to 14 times per week, for
more than or equal to 1 month before study entry), were included. During the baseline week, general demographic characteristics,
hot flash information, and quality of life data were obtained. At the beginning of week 2, patients were started on levetiracetam
for a total of 4 weeks. Information about hot flashes, quality of life, and toxicity were collected during these 4 weeks and
compared with the baseline week.
Main results After treatment with levetiracetam for 4 weeks (N = 19), mean hot flash scores (frequency times mean severity) were reduced by 57%, and mean hot flash frequencies were reduced
by 53%, compared to the baseline week; both these reductions were greater than what would be expected with a placebo (20–25%
reduction). There were significant improvements in abnormal sweating (p = 0.004), hot flash distress (p = 0.0002), and satisfaction of hot flash control (p = 0.0001), when comparing data from the fourth week of treatment to the baseline week. Twenty-nine percent of the subjects
did not complete the study because of treatment-related adverse events, with the most frequently reported side effects being
somnolence, fatigue, and dizziness, usually with mild to moderate intensity.
Conclusion The results of this pilot trial suggest that levetiracetam might be an effective therapy for the treatment of hot flashes.
Further data are needed to test this hypothesis, evaluating the efficacy and toxicity of this agent.

目的比较单用热敷法与热水袋+土豆片湿热敷法预防肌注后硬结发生的疗效,寻找预防长期肌注后硬结的最有效方法。方法选择120例肌注黄体酮的患者,采用自身对照,在每例患者的两侧臂大肌首次注射后,分别用热敷法(热敷组)和热水袋+土豆片湿热敷(联用组),观察患者注射局部硬结的发生率,疼痛程度。结果联用组较热敷组局部硬结的形成及疼痛发生率低,两者比较差异有统计学意义(P〈0.001)。结论联用法预防肌注后硬结的发生,减轻患者疼痛效果优于单用热敷法。 相似文献

Objectives
During menopausal transition autonomic balance is known to shift towards sympathetic dominance, but the role of vasomotor hot flushes in this phenomenon is not understood. We compared cardiovascular autonomic responsiveness between women with and without hot flushes.Study design and main outcome measures
One hundred fifty recently postmenopausal healthy women with varying degree of hot flushes (none, mild, moderate, severe) underwent comprehensive cardiovascular autonomic nervous testing (controlled and deep breathing, active orthostatic test, Valsalva manoeuvre and handgrip test) assessing both sympathetic and parasympathetic activity. The responses of heart rate, heart rate variability and blood pressure in these tests were evaluated.Results
Responses in heart rate showed differences between the study groups only in the Valsalva manoeuvre where the tachycardia ratio in all symptomatic women was lower (p = 0.041) than in women without hot flushes. Neither change in the heart rate variability analyses nor the blood pressure responses were affected by hot flush status. However, there was a non-significantly higher maximum systolic (140 (112–182) mmHg vs. 135 (102–208) mmHg) and diastolic blood pressure (94 (72–112) mmHg vs. 90 (66–122) mmHg) following the handgrip test in women without hot flushes vs. all the symptomatic women.Conclusions
Menopausal hot flushes seem to be associated with a possibly increased sympathetic preponderance without an effect on parasympathetic activity in cardiovascular autonomic responses. This may imply a potentially negative impact on cardiovascular health in women experiencing hot flushes. 相似文献57.
In breast cancer patients, menopausal symptoms such as hot flashes, urogenital problems, musculoskeletal symptoms and cognitive dysfunction are common, regardless of age at diagnosis. They affect quality of life and systemic therapy will worsen this. Endocrine and/or chemotherapy may induce temporary or permanent ovarian failure and can exacerbate these symptoms. Hormone therapy (HT) has been studied in breast cancer survivors, but safety has been questioned. The HABITS trial investigating estrogen-based HT, as well as the LIBERATE trial investigating tibolone, found a reduction in disease-free survival for those treated. Alternative strategies are needed, as menopause symptoms may reduce compliance with breast cancer treatments. This article reviews recently published strategies to tackle menopausal problems in breast cancer patients. Antidepressants may help with hot flashes. Acupuncture and hypnosis can also be used but the evidence is conflicting. For urogenital problems vaginal moisturizers or topical estrogens can be employed. A musculoskeletal syndrome induced by aromatase inhibitors (AIs) is frequently encountered and currently there are no effective treatment strategies. Bisphosphonates reduce AI-induced bone resorption and can also increase disease-free and overall survival. Standard-dose endocrine and chemotherapy are associated with a decline in cognitive function. 相似文献

The increased risk of breast cancer recently observed with some specific estro-progestin associations has raised concerns about the harmful effects of menopausal hormone replacement therapy (HRT). It has been proposed that phytoestrogens (PEs), which have a similar chemical structure to estrogens, could be used as HRT. The main selling points of these preparations concern the management of hot flashes and their potential beneficial effects on breast tissue. In this review, we will address the effects of PE on hot flashes and breast cancer risk as well as the questions raised on a chemical point of view. We conclude that the efficacy of a PE rich diet or nutritional supplements is not clearly established. The use of PE as an alternative for HRT cannot be advocated for now, due to insufficient and conflicting data on efficacy and safety. Moreover, due to the hormone dependence of breast cancer, PE use must be contraindicated in breast cancer survivors. 相似文献

Reversible attenuation of neuropathic-like manifestations in rats by lesions or local blocks of the intralaminar or the medial thalamic nuclei 总被引:1,自引:0,他引:1

BACKGROUND AND AIM: Thalamic somatosensory nuclei have been classified into medial and lateral systems based on their role in nociception. An imbalance between these two systems may result in abnormal somatic sensations and spontaneous pain. This study aims to investigate the effects of transient or permanent block of the medial and intralaminar nuclear groups on the neuropathic-like behavior in a rat model for mononeuropathy. METHODS: Neuropathy was induced on one hind paw in different groups of rats following the spared nerve injury model. When the resulting hyperalgesia and allodynia (tactile and cold) reached a maximum plateau, the rats received either chemical or electrolytic lesion or lidocaine (2%) microperfusion, placed in the various thalamic nuclear groups. RESULTS: All procedures produced transient but significant decrease of neuropathic manifestations. The magnitude and duration of decrease depended on the type and the site of the block. These effects can be ranked in increasing order as follows, electrolytic相似文献
