概括
周关节注射 (PAI) 在结合内吗啡 (ITM) 脊髓麻醉后,没有减少全膝关节整形术 (TKA) 后的阿片类药物使用. 这表明PAI可以在使用ITM的TKA协议中安全地省略.
科学领域:
- 整形外科手术 整形外科手术
- 麻醉学 麻醉学
- 疼痛管理 疼痛管理
背景情况:
- 周关节注射 (PAI) 是全膝关节整形术 (TKA) 多模式止痛的组成部分.
- 在此之前,PAI与神经轴麻醉,特别是内吗啡 (ITM) 的组合尚未被评估.
- 这项研究研究了PAI在TKA患者接受脊柱麻醉与ITM的疗效.
研究的目的:
- 为了前性地比较PAI与安慰剂在降低TKA后术后阿片类药物消费方面的有效性.
- 评估PAI在TKA后的前48小时内对阿片类药物需求的影响.
- 为了确定PAI是否是止痛的必要组成部分,当使用ITM脊柱麻醉时.
主要方法:
- 进行了一项前性,双盲,随机对照试验.
- 接受TKA的患者接受了结合脊柱-外皮麻醉与ITM和多模式止痛.
- 研究小组接受了PAI与罗皮瓦卡因,克罗尼丁,凯托洛拉克和上腺素;对照组接受了盐水安慰剂注射.
主要成果:
- 在PAI组 (125.49MME) 和对照组 (138.80MME) 之间,在术后的阿片类药物消费总量上没有观察到统计学上显著的差异.
- 在TKA后0-24小时和24-48小时的阿片类药物需求也在两组之间相似.
- 该研究不足以检测出显著的差异,但趋势有利于PAI没有额外的好处.
结论:
- 周关节注射 (PAI) 在使用内吗啡 (ITM) 脊髓麻醉时,不会显著降低全膝关节整形术 (TKA) 患者的阿片类药物消耗.
- 当ITM是麻醉协议的一部分时,PAI可能会被排除在外,而不会对术后阿片类药物需求产生不利影响.
- 用更大的样本大小进行进一步的研究可能是有必要的,但目前的发现表明TKA止痛方案的潜在简化.

Opioid Analgesics: Synthetic and Semisynthetic Opioids
204
Synthetic and semisynthetic opioids are pivotal in pain management and tackling opioid addiction. Semisynthetic opioids, including morphinans (morphine derivatives), oxycodone, oxymorphone, hydrocodone, and hydromorphone, have improved pharmacokinetic profiles compared to morphine. Additionally, heroin and 6-MAM (6-Monoacetylmorphine) show better CNS penetration than morphine due to heightened lipid solubility. Hydromorphone, a potent opioid, undergoes hepatic metabolism to form the active...

Analgesia and Pain Management
422
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

Local Anesthetics: Clinical Application as Epidural Anesthesia
406
Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

Local Anesthetics: Clinical Application as Spinal Anesthesia
569
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...
