18类常用急救药品

18种急救药品八种高危药品:1、重酒石酸去甲肾上腺素注射液(正肾)【药理作用】为肾上腺素受体激动药,是强烈的α受体激动药,同时也激动b受体。

通过α受体激动,也可引起血管极度收缩,时血压升高,冠状动脉血流增加;通过b受体的激动,时心肌收缩加强,心排出量增加。

【适应症】用于治疗急性心肌梗死,体外循环引起的低血压,对血容量不足所致的休克、低血压或嗜铬细胞瘤切除后的低血压,本品作为急救时补充血容量的辅助治疗,使血压回升,暂时维持脑与冠状动脉灌注,直到补充血容量发生作用;也可用于椎管内阻滞时的低血压及心跳骤停复苏后血压维持。

【规格】1ml:2mg【用法用量】用5%葡萄糖注射液或葡萄糖氯化钠注射液稀释后静滴。

【不良反应】1药液外漏可引起局部组织坏死。

2本品强烈的血管收缩可以使重要脏器器官血流减少,肾血流锐减后尿量减少,组织供血不足导致缺氧和酸中毒,之久或大量使用时,可使回心血量减少,外周血管阻力升高,心排血量减少,后果严重。

3应重视的反应包括静脉输注时沿静脉径路皮肤发白,注射局部皮肤破溃,皮肤紫癜,发红,严重眩晕,上述反应虽属少见,但后果严重。

4个别病人因过敏而有皮疹,面部水肿。

5在缺氧,电解质平衡失调、器质性心脏病病人中或逾量时,可出现心律失常,血压升高后可出现反射性心率减慢。

6以下反应如持续出现应注意:焦虑不安、眩晕、头疼、皮肤苍白、心悸、失眠等。

7逾量时可出现严重头痛及高血压、心率减慢、呕吐、抽搐。

2、盐酸肾上腺素注射液(副肾)【药理作用】可兴奋α、β二种受体。

兴奋心脏β1-受体,使心肌收缩力增强,心率加快,心肌耗氧量增加;兴奋α-受体,可收缩皮肤、粘膜血管及内脏小血管,使血压升高;兴奋β2-受体可松驰支气管平滑肌,解除支气管痉挛。

用于过敏性休克、心脏骤停、支气管哮喘、粘膜或齿龈的局部止血等。

【用法】1.抢救过敏性休克:肌注0.5~1mg/次,或以0.9%盐水稀释到10ml缓慢静注。

如疗效不好,可改用2~4mg溶于5%葡萄糖液250~500ml中静滴。

18 types of commonly used rescue drugs(For emergencydepartment only)1. Central nervous system stimulantsNicosame (Colamin)[Pharmacology andapplication] Directly excite the medulla oblongata respiratory center to deepen and speed up breathing. It also has a weak excitatory effect on the vascular movement center. Used for central respiratory depression and circulatory failure, poisoning of anesthetics and other central depressants.[Usage] Common dosage: intramuscularly or intravenously, 0.25-0.5g/time, repeat 1 to 2 hours if necessary. Maximum amount:1.25g/time.[Note] Large doses can cause elevated bloodpressure, palpitations, sweating, vomiting, arrhythmia, tremor and convulsions.Lobeline (Lobeline)[Pharmacology and application] Exciting carotid body chemoreceptors and reflex excitement of respiratory center. It is used for neonatal asphyxia, inhalation anesthetics and other central depressant poisoning, carbon monoxide poisoning and respiratory failure caused by pneumonia.[Usage] Common dosage: intramuscularly or intravenously, 3 mg/time,repeat in half an hour if necessary. The maximum amount is 20mg/day.[Note] Adverse reactions include nausea, vomiting, diarrhea, headache, dizziness; large doses can cause tachycardia, respiratory depression, blood pressure drop, and even convulsions.2. Anti-shock vasoactive drugsDopamine[Pharmacology and application] Directactivation of α and β receptors, as well as dopamine receptors. The effect on different receptors is related to the dose: low-dose (2~5μg/kg•min) l ow-speed instillation, excites dopamine receptors, Dilate the kidneys, mesenteric, coronary arteries and cerebral vessels, increase blood flow and urine output. At the same time, it stimulates the β1 receptors of the heart, and also produces a moderately programmed positive inotropic effect by releasing norepinephrine; at a medium dose (5~10μg/kg•min), it can obviously activate β1 receptors to excite the heart and strengthen the myocardium. Contraction force. At thesame time, it also stimulates alpha receptors, causingperipheral blood vessels such as skin and mucous membranes to contract. At high doses (>10μg/kg•min), the positive muscle strength and vasoconstriction effect are more obvious, and the renal vasodilation effect disappears.Positive muscle strength and renal vasodilatation are dominant in medium and low-dose anti-shock therapy.
