概括
在怀孕后期,母亲使用止痛药可能会导致胎儿导管收缩,特别是与metamizole. 乙氨基也显示出轻微的,可逆的效应,表明前列腺素介导的机制需要多普勒监测.
科学领域:
- 围产儿医学 围产儿医学
- 胎儿心脏病学 胎儿心脏病学
- 药理学 药理学是指药理学的学科.
背景情况:
- 在怀孕晚期,母亲使用止痛药是常见的.
- 对胎儿血液动力学,特别是管道和肺动脉的潜在影响需要调查.
- 了解药物特异性影响,比如甲米醇与乙氨基,至关重要.
研究的目的:
- 评估妊娠晚期母亲暴露于止痛药 (甲米醇,乙氨基) 和胎儿管道/肺血液动力学之间的关联.
- 为了比较甲米醇和乙氨基对胎儿导管收缩的影响.
- 评估药物停止后观察到的血液动力学变化的可逆性.
主要方法:
- 67例第三个月妊娠 (47例暴露,20例对照) 的前性队列研究.
- 在暴露期间 (T1) 和药物戒断后 (T2) 进行的连续胎儿心声图.
- 对管道收缩进行评估的多普勒参数 (PI,速度);对肺血液动力学进行评估的MPAP和AT/ET.
主要成果:
- 胎儿导管收缩发生在38.3%的暴露胎儿中,而对照组为0% (p=0.00065).
- 甲米醇暴露的收缩率比乙氨基 (20%) 高 (52%).
- 甲醇的使用,最近的暴露和更高的剂量独立地与收缩有关;在停药后,影响是可逆的.
结论:
- 在怀孕晚期,母亲使用止痛药与胎儿导管收缩有关.
- 与乙氨基相比,梅塔米佐尔表现出更强的,与剂量相关的与收缩的联系.
- 这些发现强调了在妊娠晚期暴露于前列腺素调节剂的胎儿中进行多普勒监测的必要性.

Analgesia and Pain Management
2.4K
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
875
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: Differential Sensitivity of Nerve Fibers
1.5K
Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...
