概括
上腺素 (NE) 是治疗脊髓麻醉诱导的低血压 (SAIH) 在剖腹产 (CD) 期间最有效的血管压缩剂,与上腺素 (PE) 和上腺素 (EP) 相比,显示出更好的孕产妇和新生儿结果. 这一发现支持优先使用NE来管理脊柱后低血压 (PSH).
科学领域:
- 麻醉学 麻醉学
- 产科 产科 产科 产科 产科
- 药理学 药理学是指药理学的学科.
背景情况:
- 脊柱麻醉诱导的低血压 (SAIH) 是剖腹产 (CD) 期间经常出现的并发症,可能会影响母亲和胎儿的健康.
- 上腺素 (NE),上腺素 (PE) 和上腺素 (EP) 是常见的治疗方法,但它们的相对有效性和安全性概况尚未得到充分确立.
研究的目的:
- 为了比较NE,PE和EP在低风险选择性CD期间管理脊柱后低血压 (PSH) 的疗效和耐受性.
- 在这种临床背景下为血管压缩剂选择提供基于证据的建议.
主要方法:
- 进行了随机对照试验 (RCT) 的系统审查和网络元分析 (NMA),包括到2025年6月的数据.
- 包括16个RCT与2,102分娩者,评估结果,如PSH纠正,孕产妇胸,恶心/吐,和新生儿参数 (阿巴格分数,动脉pH值).
- 使用Cochrane RoB 2和GRADE方法分别评估了偏差风险和证据确定性;试验序列分析 (TSA) 证实了这些发现.
主要成果:
- 与PE和EP相比,上腺素 (NE) 在逆转PSH方面表现出更高的有效性 (OR:0.23) 并与明显较少的孕产妇不良事件相关,包括胸肌梗塞 (OR:0.28) 和恶心/吐 (OR:0.36),与PE和EP相比.
- 新生儿结局在血管压缩剂组之间是可比的,NE在减少新生儿酸性病症方面有有利的趋势 (动脉pH OR:1.25).
- 网络元分析排名和TSA支持NE的稳定性和优越性.
结论:
- 上腺素 (NE) 是治疗选择性剖腹产 (CD) 中脊髓麻醉诱导的低血压 (SAIH) 的最有效和最好耐受的血管压缩剂.
- NE使用不会影响新生儿安全,并显示出改善新生儿酸性结局的趋势.
- 这些发现支持在这种患者群体中偏好使用NE而不是乙烯 (PE) 和乙烯 (EP) 来管理PSH.

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...

Cardiopulmonary Resuscitation IV: Pharmacological Management
675
Pharmacologic intervention is crucial in treating cardiac arrest patients during ACLS or Advanced Cardiovascular Life Support. The ACLS algorithms guide the administration of specific drugs based on the patient's cardiac arrest rhythm, which includes pulseless ventricular tachycardia (VT), ventricular fibrillation (VF), asystole, and pulseless electrical activity (PEA).EpinephrineIndication: Epinephrine is the first-line drug for all cardiac arrest rhythms.Mechanism of Action: Epinephrine...

Cardiac Catheterization IV: Nursing Management

Nursing responsibilities before cardiac catheterization include:Assess for allergies and establish baseline health status.Before cardiac catheterization, assess the patient for allergies to contrast dye. Perform a comprehensive baseline assessment, including vital signs, heart and breath sounds, and a neurovascular assessment of the extremities, noting distal pulses, skin color, and temperature. Instruct the patient to fast for 8-12 hours before the procedure. Evaluate baseline laboratory...

Antihypertensive Drugs: Vasodilators
2.0K
Vasodilators, primarily affecting the smooth muscles within arterial and venous walls, are commonly used for hypertension treatment. Medications such as minoxidil and hydralazine primarily target arteries and arterioles, while sodium nitroprusside acts on arterioles and venules. Minoxidil, functioning as a prodrug, is metabolized by hepatic sulfotransferase into its active form, minoxidil sulfate, after oral administration. This metabolite binds to the sulfonylurea receptor (SUR) component of...

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.
