浅谈中医生活护理
【关键词】中医 生活护理 环境 起居
中图分类号：R248文献标识码：B文章编号：1005-0515(2011)10-142-01
人们的日常生活起居及周围环境，与人体的健康具有密切关系。住院病人的生活起居条件，直接影响着治疗效果。生活护理，就是要对病人的日常生活起居加以照料，包括为病人提供一个良好的休养环境，使病人早日康复。古代医家对此积累了丰富的经验，可概括为以下两方面。
1 病区环境要求
1.1 病室整洁，温度、湿度、及光线适宜
明代陈实功《外科正宗》中指出：“先要洒扫患房洁净”，“冬要温床暖室，夏宜净几明窗”。这是对病人居住环境的基本要求。
病室内的卫生环境，直接影响患者的身体健康。应当指导病室的所有人员，都要关心并随时注意保持室内的整洁。病室内的陈设应力求简单实用，易于搬动，便于打扫，同时要便于医生查体和临床护理操作。除设置病人必须用品外，其余物品应当让家属带回。要定时打扫病室，要求门窗四壁净，天棚地板净。室内要湿式擦洗，防止灰尘飞扬。患者床单必须保持清洁、平整、干燥。床头柜要擦干净，病人的物品放置也要有规律。病人出院后，要清理床铺，更换被服，擦洗床头柜，整理病人用过的一切用品，进行消毒，做好迎接新患者的准备。
在保持室内整齐、干净的同时，还要适当调节室内的温度、湿度以及光线。病室温度以 18～20°C为宜。。过低会使病人感到寒冷，过高病人会感到炎热不适。病人对气温感觉有一定差别，应加以注意。老年人和阳虚阴盛之体多畏寒，室温宜偏高;年轻人和阴虚阳盛之体多恶热，室温宜偏低。外感风寒者，多恶风寒，要注意保温，室温宜偏高;里热亢盛者，但热不寒，要注意通风，室温宜偏低。若室温过高时可开窗通风或用电扇调节，但须注意不要让冷风直接吹在病人身上。《天隐子养生书》中指出：“避风如避箭，若盛暑所居，两头通屋，弄堂夹道，风回凉爽，其为害尤甚。养生者当慎之。”冬季若室温过低，要注意关紧门窗，并增加衣被或用热水袋以取暖。病人对室温要求不同时，可以通过加减衣被来调节。尤其应注意的是，北方冬季寒风凛冽，病室的窗户应当封好，仅留有气窗，以免靠窗病床的病人感受风邪。《保生要录》曾指出：“常坐之处，令其四面周密，勿令小有细隙，致风得入。人不易知，其伤人最重。初时不觉，久能中人。”总之，四时气候变化很大，要注意调节病室的温度。
室内空气湿度也须适当调节。湿度过高，汗液的蒸发受阻，病人会感到潮湿憋闷。脾虚湿盛及风寒湿痹患者，对此就更为敏感，往往会使病情加重。湿度过低，病人会感到口鼻干燥，咽喉不适。火热亢盛者就更觉口渴欲饮，特别是阴虚肺热者，常常会因此而诱发鼻衄、呛咳。一般室内的相对湿度应以55%～65%为宜。湿度过高，可开窗通风。湿度过低，可在室内洒水或用湿拖布擦地，冬季可在暖气上放湿毛巾以提高湿度。
另外，室内光线宜充足，使病人感到舒适愉快，同时也便于医护人员诊疗及护理操作。夏季正午，室内光线过强时可用窗帘适当遮蔽强光。正如《天隐子养生书》所云，室内应当“阴阳适中，明暗相半”，“太明即下帘，以和其内映，太暗则�帘，以通其外耀。内以安心，外以安目，心目具安，则身安矣”。说明光线的调节对病人很重要。
1.2 居处安静、空气新鲜
《素问・生气通天论》曰：“苍天之气，清净则志意治・・・・・・。”说明人的精神情志与外界环境密切相关。安静的环境，清新的空气，会使人感到心情愉快，身体舒适。相反，人声嘈杂，机器轰鸣小儿啼哭，会令人烦恼。病人的心理常常是紧张、焦急、烦恼、不安。对普通人来说几乎是无所谓的一点点声响，对病人来说可能就是一种不良刺激，往往会使病情加重。例如，心气虚者，甚至一声门响都会使之心悸不已;走廊的脚步声，会使患者彻夜不眠。因此医护人员要重视并保证病室内及周围环境的安静。使病人得到充分的休息和睡眠，从而精神振作，食欲增加，有利于疾病的康复。
保持病区内外环境的空气新鲜也是非常重要的。室内空气混浊，会使人感到头晕、疲倦，因此病室内严禁吸烟，同时要注意室内通风。夏季天气炎热，应经常打开门窗通风换气，其他季节可视情况而定每天至少1～2次。冬季气候寒冷，只能打开小气窗，时间不宜过长，切勿使空气对流。通风前要做好病人的保暖工作，防止病人受凉而感冒。
1.3 瘟疫劳瘵，消毒隔离
瘟疫是具有强烈传染性和流行性的一类急性热病的总称 。劳瘵则是一种具有传染性的慢性虚损性疾患。对于传染病的护理要注意食具、衣物以及病室空气的消毒，要采取隔离治疗的方法，以免传染给他人。但有时往往由于医生的误诊而将传染病患者收入普通病房。尤其在传染病流行季节，护士更应提高警惕，发现后立即将患者转至专科病房，并对原病房内外进行严格的消毒。
2 病人起居护理
2.1 法于阴阳，起居有常
中医认为自然界与人体是一个有机的整体，自然界季节、气候的变化，必然会使人体产生相应的反应，即“人与天地相应”。因此，在护理工作中，也应根据自然界四时阴阳的变化规律，指导患者的日常生活起居。春季天气由寒转暖，但气候不稳定，乍寒乍热，宣暄不一，所以当告知患者“不可顿去棉衣”。尤其是老年人，“气弱骨疏体怯，风冷易伤腠理”，应当提醒他们根据气温的变化，随时加减衣被。并且多主张“棉衣晚脱，不可令背寒”，“春不可衣薄”，“衣欲下厚而上薄”。夏季万物生长茂盛，人体阳气也发散于外，可以晚些入睡，但应早起锻炼身体。夏季天气炎热，不可让病人图一时之快而在空气对流的过道、弄堂中乘凉，也“不得于星月下露卧”，或睡眠中令人扇风取凉。秋季天气渐凉，人体阳气应当收敛，要“早卧早起”。秋季某些旧病容易复发，所以“宜和平将摄”。冬季天寒地冻，人体“伏阳在内”，可以“早卧晚起”，病室宜保暖，“去寒就温，无泄皮肤”。但也不可过暖，“棉衣当晚着，使渐渐加厚”。尤其是老年人“骨肉疏薄”，易感外邪，冬季不宜早起外出，以免感受风寒。总之，应该根据四时的变化，加以调护。
2.2 沐浴更衣，讲究卫生
使住院患者养成良好的卫生习惯，对于预防疾病的互相传播具有积极意义，有条件的地方，应当在病人入院时即给予沐浴，然后更换住院服，再送入病区。护士要督促轻患者搞好个人卫生，每日早晚要刷牙，每餐后要漱口，饭前、便后要洗手，勤剪指甲，经常保持皮肤及口腔的清洁。每晚临睡前要洗脸洗脚。用温水洗脚可以促进气血流通，帮助去除疲劳，以获得良好的睡眠。夏季天气炎热，人体汗出较多，应当勤洗澡，勤换衣裤。其他季节可根据情况1～2周左右沐浴一次，以保持皮肤清洁，衬衣也要每周换洗一次。孙思邈曾指出：“饥忌浴，饱忌沐。”我们应当注意宣传，以免患者空腹洗澡后发生晕厥。对卧床不起的病人，护士应当定期给予床上擦浴、洗头、修剪指甲，对于二便失禁的病人，要勤换尿布，勤擦洗，保持臀部干燥，防止发生褥疮。同时还要经常做好卫生宣传，指导病人不但要搞好个人卫生，还要保持公共卫生，不要随地吐痰，乱扔果皮等。
2.3 动静结合，促病痊愈
住院病人应当很好休息，以保持体力，有助于病体康复。适当的运动，可以使经络通畅，营卫气血调和，增加抵御外邪的能力，所以住院病人也应动静结合。要根据每个人的具体情况，适当安排休息和运动，不宜过分强调休息。急性病和危重患者须卧床休息，日常生活要由护理人员帮助，随着病情的好转，可在床上做适量的活动。大病初愈，也应当注意休息，待体力恢复后，再循序渐进地适当运动。慢性病和恢复期病人，不可久卧病榻，“久卧伤气”，对机体不利，可以到户外活动，如散步、做体操、打太极拳等，使血脉流通，以利于疾病的恢复。
