心脏瓣膜置换术后患者的出院准备度现状及其影响因素分析

目的:调查心脏瓣膜置换术后患者的出院准备度现状,并分析其影响因素。方法:于2018年9月至2019年3月用一般资料、出院准备度量表、出院指导质量量表对139例瓣膜置换术后患者进行调查。结果:心脏瓣膜置换术后患者的出院准备度总分为(89.51±8.53)分,与出院指导质量呈正相关;多元回归分析显示,主要照顾者、婚姻状况、工作状态、服药种类、出院指导质量为出院准备度影响因素。结论:心脏瓣膜置换术后患者的出院准备度有待提高,患者感知的个人状态得分不理想;护士应鼓励患者配合进行早期康复,强化出院指导,采取有效措施提供康复信息,满足患者及其家属需求,提高出院准备度。     

中医药外治疗法治疗混合痔术后并发症临床研究概况

混合痔在其多样化的治疗方案中通过手术治疗是最主要的方法,但因肛管解剖结构和生理功能的特殊性、复杂性,且开放的术口会因排便刺激而损伤局部组织,造成肛门部水肿、疼痛、创面延期愈合等并发症出现,降低患者的生活质量并带来极大的身心痛苦。西医治疗主要是抗感染、止痛、止血等对症处理为主; 而中医治疗是以辨证论治为基础,达到消肿止痛、活血化瘀、抗炎促愈的目的,疗效稳定,尤其是中医外治疗法通过中药熏洗坐浴、灌肠塞肛及针灸敷药等方式直接作用于切口患处,减少胃肠道刺激,发挥多靶点、多环节、多层次的综合调控作用而增加疗效,其成本低、易操作、简便易行,能促进水肿消退、缓解疼痛、减少出血及创面早日愈合。现就混合痔术后并发症的中医药外治疗法进行综述如下。

目的 :评价改良引流法用于肛肠术后的临床价值。方法 :用半随机方法将 10 0例患者分为观察组和对照组 ,各 5 0例 ,对肛肠术后患者切口分别采用传统引流法和改良引流法 ,比较术后出现的并发症及并发症出现的平均时间。结果 :观察组术后并发症和并发症出现的时间少于对照组 (P <0 0 5 )。结论 :改良引流法能减轻患者痛苦 ,疗效好 ,并发症少。     

Differences in plans for living at home between temporary residents of a health-care facility for the elderly and their family caregivers in Japan

Aim: Older residents in Japan requiring rehabilitation often reside in health‐care facilities for the elderly (HCFE) prior to being discharged to home. The return home can be very stressful for both the elder and family caregiver. The purpose of this study was to clarify the differences in plans for home life between the residents of a HCFE who were scheduled for discharge home and their family caregivers. Method: Semistructured interviews were conducted with eight pairs of elders and caregivers. Results: Differences were seen in several areas, including dietary preferences, recognition of the elder’s independence, preconceptions or not knowing about the elder’s pleasurable activities, and the way of care. Conclusions: Differences with regard to enjoyable activities for the elderly arose from a lack of understanding of the lives of the elderly on the part of their families.     

Patient readiness for return to home: Discord between expectations and reality

This study examined the interface between acute hospital care and return to home in relation to elderly patients' perceived ability and preparedness to cope at home. Seventy-six (n = 76) elderly patients aged 60 years and over were randomly recruited from a large Queensland hospital and interviewed prior to discharge about their perceived health, functional status and their ‘readiness’ to cope at home. They were followed up at home 7–10 days post-discharge. Comparisons were made between a number of measures at discharge and post-discharge. Although the majority of patients indicated that they would cope very well upon discharge, a large number of patients reported experiencing considerable difficulty with activities of daily living, particularly instrumental activities of daily living prior to and especially after discharge. The self-reported health status of patients similarly deteriorated between discharge and follow-up. Despite a large number of patients experiencing functional limitations, few were referred to hospital or community-based therapy services. Some policy implications are explored.     

Subtype determination of soma-dendritic α2-autoreceptors in slices of rat locus coeruleus

The aim of the study was to subclassify the soma-dendritic α₂-autoreceptors in the locus coeruleus (LC) of the rat by means of antagonists. To this end, the frequency of spontaneous action potentials was recorded extracellularly from single LC neurones in brain slices. The neurones fired spontaneously at an average rate of 1 Hz. The selective α₂-adrenoceptor agonist 5-bromo-6-(2-imidazolin-2-ylamino)-quinoxaline (UK 14,304) and noradrenaline decreased the action potential discharge with IC₅₀ values of 5 and 510 nM, respectively. The concentration-inhibition curves of UK 14,304 and noradrenaline were shifted to the right by phentolamine (0.15 μM) and rauwolscine (0.15 μM) but not by prazosin (1 μM). Apparent K _d values of phentolamine were 17 nM (against UK 14,304) and 20 nM (against noradrenaline). Apparent K _d values of rauwolscine were 47 nM (against UK 14,304) and 70 nM (against noradrenaline). (+)-Oxaprotiline (1 μM) suppressed the firing of the neurones within 10 to 33 min. In the continued presence of oxaprotiline, phentolamine and rauwolscine restored firing with EC₅₀ values of 120 and 250 nM, respectively. Prazosin (1 μM) again was ineffective. All three antagonist affinity estimates – against UK 14,304, exogenous noradrenaline and endogenous noradrenaline (that accumulates in the extracellular space in the presence of oxaprotiline) – yield an affinity order phentolamine > rauwolscine >> prazosin, prazosin being ineffective even at a concentration of 1 μM. These findings identify the soma-dendritic α₂-autoreceptors of the LC as the rat variant of the α_2A/D-adrenoceptor, i.e. α_2D. Not only presynaptic but also soma-dendritic α₂-autoreceptors may at least predominantly be α_2A/D throughout the nervous system. Received: 3 March 1997 / Accepted: 21 April 1997
