毒理性

• 解毒与急救

/SRP:/ 立即急救：将患者从接触物质中移开。确保已经进行了充分的去污处理。如果患者停止呼吸，开始人工呼吸，最好使用需求阀复苏器、袋阀面罩装置或口袋面罩，按训练操作。如有必要，进行心肺复苏。立即用缓慢流动的水冲洗受污染的眼睛。不要催吐。如果发生呕吐，让患者向前倾或放在左侧（如果可能的话，头部向下），以保持呼吸道通畅，防止吸入。保持患者安静，维持正常体温。寻求医疗救助。 /无机碱/碱性腐蚀物及相关化合物/

/SRP:/ Immediate first aid: Remove patient from contact with the material. Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on the left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Inorganic Bases/Alkaline Corrosives and Related Compounds/

• 解毒与急救

/SRP:/ 基本治疗：建立专利气道（如有需要，使用口咽或鼻咽气道）。如有必要，进行吸痰。密切观察呼吸不足的迹象，如有必要，进行辅助通气。通过非重复呼吸面罩以6至12升/分钟的速度给予氧气。监测肺水肿，并在必要时进行治疗……。监测休克，并在必要时进行治疗……。对于眼睛污染，立即用水冲洗眼睛。在运输过程中，用0.9%的生理盐水（NS）持续冲洗每只眼睛……。不要使用催吐剂。对于摄入，如果患者能够吞咽、有强烈的呕吐反射且不流口水，则用水冲洗口腔，并给予5毫升/千克，最多200毫升的水进行稀释……。不要尝试中和。在去污后，用干燥的无菌敷料覆盖皮肤烧伤……。/无机碱/碱性腐蚀剂及相关化合物/

/SRP:/ Basic treatment: Establish a patent airway (oropharyngeal or nasopharyngeal airway, if needed). Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 6 to 12 L/min. Monitor for pulmonary edema and treat if necessary ... . Monitor for shock and treat if necessary ... . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with 0.9% saline (NS) during transport ... . Do not use emetics. For ingestion, rinse mouth and administer 5 ml/kg up to 200 ml of water for dilution if the patent can swallow, has a strong gag reflex, and does not drool ... . Do not attempt to neutralize. Cover skin burns with dry sterile dressings after decontamination ... . /Inorganic Bases/Alkaline Corrosives and Related Compounds/

• 解毒与急救

/SRP:/ 高级治疗：对于昏迷、严重肺水肿或严重呼吸困难的病人，考虑进行口咽或鼻咽气管插管以控制气道。在上呼吸道阻塞的最初迹象出现时，可能需要早期插管。使用气囊面罩装置的正压通气技术可能有益。考虑对肺水肿进行药物治疗...。监测心率和必要时治疗心律失常...。开始静脉输注D5W /SRP: "保持开放"，最低流量/。如果出现低血容量的迹象，使用0.9%生理盐水（NS）或乳酸钠林格氏液（LR）。对于伴有低血容量迹象的低血压，谨慎给予液体。如果病人在正常液体容量下出现低血压，考虑使用血管收缩剂。注意观察液体过载的迹象...。使用丙美卡因氢氯化物协助眼部冲洗...。/无机碱/碱性腐蚀剂及相关化合物/

/SRP:/ Advanced treatment: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious, has severe pulmonary edema, or is in severe respiratory distress. Early intubation, at the first signs of upper airway obstruction, may be necessary. Positive-pressure ventilation techniques with a bag valve mask device may be beneficial. Consider drug therapy for pulmonary edema ... . Monitor cardiac rhythm and treat arrhythmias as necessary ... . Start IV administration of D5W /SRP: "To keep open", minimal flow rate/. Use 0.9% saline (NS) or lactated Ringer's (LR) if signs of hypovolemia are present. For hypotension with signs of hypovolemia, administer fluid cautiously. Consider vasopressors if patient is hypotensive with a normal fluid volume. Watch for signs of fluid overload ... . Use proparacaine hydrochloride to assist eye irrigation ... . /Inorganic Bases/Alkaline Corrosives and Related Compounds/
