Ketamine has been recognized as an anesthetic agent of choice in areas with limited resources, particularly in emergency situations. Unlike other commonly used induction agents, it preserves respiratory drive and maintains predominant sympathetic tone. However, ketamine's application in other clinical settings has been limited by its psychomimmetic properties, which other anesthetics do not posses. Despite these drawbacks, ketamine has become a favorable drug for the sedation of children undergoing various procedures. Here we propose 3 clinical paradigms where ketamine may be the agent of choice for the pediatric patient requiring sedation or anesthesia, including (1) the child with a difficult airway, (2) the child with a reactive airway disease, and (3) the uncooperative child requiring intravenous access.
氯胺酮已被公认为资源有限地区(尤其是紧急情况下)的首选麻醉剂。与其他常用的诱导剂不同,它能保持呼吸驱动力并维持主要的交感神经张力。然而,氯胺酮在其他临床环境中的应用受到其精神拟态特性的限制,而其他麻醉剂则没有这些特性。尽管存在这些缺点,氯胺酮已成为接受各种手术的儿童镇静的首选药物。在这里,我们提出了 3 种临床范例,在这些范例中,氯胺酮可能是需要镇静或麻醉的儿科患者的首选药物,包括(1)气道困难的儿童,(2)有反应性气道疾病的儿童,以及(3)需要静脉通路的不合作儿童。
