概括
结合脊髓-外周止痛 (CSE) 止痛疗法在产妇中减少了与外周止痛疗法 (EA) 相比的补充止痛的需要. 然而,CSE的表现并没有显著地超过持续刺穿外围治疗 (DPE),尽管它提供了更快的发病和更低的疼痛得分.
科学领域:
- 产科和妇科 产科和妇科
- 麻醉学 麻醉学
- 疼痛管理 疼痛管理
背景情况:
- 结合脊髓-外皮 (CSE) 止痛疗法提供了快速的分娩疼痛缓解.
- 在CSE中,高内阿片类药物剂量可能会引起不良反应,而超低剂量可能会缩短块的持续时间.
- 与外周止痛 (EA) 或外周穿孔外周 (DPE) 相比,在CSE中低剂量内射罗皮瓦卡因-苏芬坦尼尔降低救援止痛的疗效尚未得到充分证实.
研究的目的:
- 为了比较CSE与低剂量内罗皮瓦卡因-苏夫坦尼尔对EA和DPE在减少分娩期间需要补充止痛的有效性.
- 评估二次结果,包括发病时间,疼痛评分 (VAS) 和患者控制的外周止痛疗法 (PCEA) 的使用.
主要方法:
- 一项随机对照试验,涉及131名分娩妇女,分为EA,DPE或CSE组.
- 在CSE组接受了特定的低剂量内罗皮瓦卡因-苏夫坦尼尔组合.
- 主要结局是患者中需要补充医疗提供者为突破性疼痛提供止痛的比例.
主要成果:
- 与EA组相比,CSE组所需的补充止痛剂明显少于EA组 (22%对48%,P=0.013).
- 虽然DPE组的补充止痛需求比EA更低,但在统计学上并不显著 (30%,P=0.09).
- 在CSE和DPE组之间没有发现补充止痛需求的显著差异 (P=0.27);然而,CSE显示出更快的发病和较低的VAS得分,而不是EA和DPE (P<0.001).
结论:
- 与EA相比,低剂量静脉内罗皮瓦卡因-苏夫坦尼尔CSE有效地减少了补充止痛的需求,但不是DPE.
- 虽然CSE提供了更快的发病速度和更大的感官阻断,但其优越性比DPE还没有最终确立.
- 无论是CSE还是DPE都是临床上可接受的分娩止痛选择,当最大限度地减少突破性疼痛是优先事项时,CSE可能会被优先考虑.

Local Anesthetics: Clinical Application as Epidural Anesthesia
687
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
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...

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
1.2K
Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.

Local Anesthetics: Differential Sensitivity of Nerve Fibers
1.4K
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...

Parenteral Anesthetics: Overview
611
Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.
