Intravenous drug allocation center refers to an organization that provides high-quality products and pharmaceutical services for clinic by strictly stopping the allocation of intravenous drugs such as total parenteral nutrition, cytotoxic drugs and antibiotics by specially trained nurses in accordance with the standard operating procedures under the operating environment designed in accordance with international standards and according to the characteristics of drugs. It has changed the traditional method of mixing intravenous infusion and medication, improved the quality of infusion and ensured the safety of patients'medication. The decoration of intravenous drug distribution center found that nurses' exposure to drugs directly or indirectly in the process of dispensing and dispensing would have potential harm to their health.
一。化学要素：1.细胞毒类药物 其是治疗肿瘤的常用药物，该药物在体内不能辨别正常细胞和肿瘤细胞，因而在杀伤肿瘤细胞的同时也会对人体的正常细胞具有杀伤和抑止作用，而PIVAS护士每天都需求面对大量的细胞毒类药物，在抽吸瓶装药等药物配置过程中大量肉眼看不到的毒性微粒气雾构成可经过皮肤、眼睛、呼吸道等途径给护理人员形成潜在伤害，招致蓄积毒作用，发作过敏反响等免疫力降落的概率明显高于普通人群。2.化学消毒剂 大局部的消毒灭菌剂都具有挥发性，该些物质固然具有良好的消毒效果，但是也具有一定的腐蚀性和挥发性，而配置室内的空气又相对封锁，特别是采用紫外线消毒后，高浓度的臭氧以及甲醛？O气体可能诱发护士的各种呼吸道疾病，并可能惹起皮肤过敏以及留意力不集中记忆力降落等。
One. Chemical Elements: 1. Cytotoxic drugs are commonly used in the treatment of tumors. They can not distinguish normal cells from cancer cells in vivo. Therefore, they can kill and inhibit normal cells of human body while killing cancer cells. PIVAS nurses need to face a large number of cytotoxic drugs every day, and they have a large number of naked eyes in the process of drug allocation such as suction of bottled drugs. Invisible toxic particulate aerosol can cause potential harm to nurses through skin, eyes, respiratory tract and other ways, which can lead to accumulated toxicity and allergic reaction. The probability of immunity decline is significantly higher than that of the general population. 2. Chemical disinfectants are mostly volatile. Although these substances have good disinfection effect, they also have certain corrosiveness and volatility. The indoor air is relatively blocked, especially after ultraviolet disinfection, high concentration of ozone and formaldehyde? O gas may induce various respiratory diseases of nurses, and may cause skin allergies and loss of concentration and memory.
二：物理要素：1.利器损伤 利器损伤是PIVAS为常见的职业损伤，由于护士在药物配置的过程中，随时都有碰到各种利器的可能，如在清洁物品时被尖利器物擦伤，用针头配置药物时被针头刺伤等，这对护士来讲固然普通，但若处置不当可能存在较大的风险性。2.紫外线损伤 PIVAS室内的空气消毒多采用紫外线作为消毒物，直接接触过量的紫外线会对机体，如暴露的皮肤、眼睛等形成灼伤，特别是对眼睛的伤害更大，可能惹起角膜炎等病症。3.噪音损伤 PIVAS的噪音主要来源于生物平安柜、风机、空调系统、超净台、程度层流台以及振荡仪等，噪音可达100dB，严重超越我国对医院环境的噪音规范值35dB，极限值为45dB，而PIVAS的护士又需长时间的在这种环境下工作，严重影响人体内脏器官和神经系统，为安康埋下了隐患。
2. Physical factors: 1. Sharp injury is the most common occupational injury in PIVAS. Because nurses may encounter all kinds of sharp tools at any time in the process of drug allocation, such as abrasion of sharp objects when cleaning articles, stabbing of needles when allocating drugs with needles, etc. It is common for nurses, but there may be greater risks if not handled properly. 2. Ultraviolet radiation is often used as disinfectant for air disinfection in PIVAS rooms. Direct exposure to excessive ultraviolet radiation can cause burns to the body, such as exposed skin and eyes, especially to the eyes, which may cause keratitis and other diseases. 3. Noise damage to PIVAS mainly comes from biological safety cabinets, fans, air conditioning systems, super-clean platforms, laminar flow platforms and oscillators. Noise can reach 100 dB, which seriously exceeds the noise standard value of 35 dB and the limit value is 45 dB for hospital environment in China. The nurses of PIVAS need to work in this environment for a long time, seriously affecting the visceral organs and nervous system of human body. Kang laid a hidden danger.
Three. The social psychological factors of PIVAS nurses are heavy tasks, heavy workload, highly concentrated working hours, long-term excitement of the brain, heavy workload and occupational risks, which have increased the physical and mental harm of nurses, but also prone to insomnia, anxiety, depression and other diseases.
