概括
100毫克的内吗啡 (ITM) 在剖腹产后提供有效的镇痛,副作用较少. 更高的剂量 (125和150微克) 提供更长的缓解疼痛,但增加恶心和等不良事件.
科学领域:
- 产科和妇科 产科和妇科
- 麻醉学 麻醉学
- 药理学 药理学是指药理学的学科.
背景情况:
- 增强的恢复协议旨在优化手术后患者的治疗结果.
- 内吗啡 (ITM) 用于在剖腹产中进行术后止痛.
- 优化ITM剂量对于平衡疼痛缓解和副作用至关重要.
研究的目的:
- 在接受剖腹产的产科患者中,比较三种不同剂量的脑内吗啡 (ITM) 的有效性和副作用概况.
- 评估ITM在增强恢复协议中的作用.
主要方法:
- 一项前性队列研究,涉及574名接受重复选择性剖腹产的女性患者 (ASA 2,>18岁).
- 患者接受了100微克,125微克或150微克的ITM.
- 结果包括口服吗啡等价物,阿片类药物不含率,ITM相关的副作用,止痛的持续时间,疼痛评分和停留时间.
主要成果:
- 所有的ITM剂量都提供了有效的止痛,高剂量与增加的副作用相关.
- 与较低剂量相比,150mcg组在24小时和48小时内显示出较低的阿片类药物消耗率和较高的阿片类药物无效率.
- 100毫克组的恶心和吐明显减少,而150毫克组报告的更多.
结论:
- 所有评价的注射式吗啡剂量都有效地控制了剖腹产后的疼痛.
- 100mcg ITM剂量呈现了止痛效果和有利的副作用概况之间的最佳平衡.
- 较低的ITM剂量可能与功能限制的趋势有关.

686
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...

914
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...

850
Opioids are a class of drugs that mimic endogenous opioid peptides and act on opioid receptors, and help in pain relief. These compounds are classified as natural, synthetic, or semi-synthetic. Natural opioids, like morphine, codeine, and thebaine, are derived from the opium poppy plant (Papaver somniferum or Papaver album) and are termed opiates. Synthetic opioids are artificial, while semi-synthetic opioids combine natural and synthetic compounds. Morphine, a prototypical opioid, possesses a...

01:11Local Anesthetics: Clinical Application as Spinal Anesthesia
1.3K
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...
