概括
持续监测显示,在剖腹产后,50微克和150微克内性吗啡 (ITM) 剂量之间的呼吸速率没有显著差异. 虽然更高的剂量增加了低血事件,但它们在临床上没有显著意义,这质疑了当前的SOAP监测建议.
科学领域:
- 产科麻醉 产科麻醉 产科麻醉
- 周围生理学 周围生理学
- 术后护理 术后护理
背景情况:
- 产妇麻醉和周围生理学学会 (SOAP) 提供了基于内吗啡 (ITM) 剂量监测剖腹产后呼吸抑制的指导方针.
- 支持这些特定监测建议的证据需要进一步调查.
研究的目的:
- 在接受剖腹产分娩的妇女中,比较ITM管理后的呼吸指标.
- 评估当前SOAP监测建议的证据基础.
主要方法:
- 一项前性观察队列研究招募了在脊髓麻醉下进行非紧急剖腹产的妇女.
- 手术后的镇痛包括50μg ITM,150μg ITM或横腹平面 (TAP) 阻断.
- 持续呼吸率 (RR) 和氧和 (SpO2) 在手术后长达12小时被监测.
主要成果:
- 喘 (RR ≤8次/分钟) 在50μg组的81.8%和150μg组的87.0%发生.
- 与50μg组 (中位数48秒) 相比,150μg组 (中位数56秒) 的低氧症持续时间明显延长.
- 在50微克和150微克ITM组之间没有观察到RR的统计学上显著差异;护理评估错过了所有呼吸事件.
结论:
- 连续监测没有显示出50微克和150微克的ITM剂量之间呼吸速率的统计学上显著差异.
- 尽管150μg ITM的低氧化事件发生率较高,但这些事件被认为不具有临床意义.
- 调查结果表明,需要重新评估目前的SOAP建议,以基于ITM剂量的呼吸监测强度.

Parenteral Anesthetics: Overview
844
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.

Local Anesthetics: Clinical Application as Epidural Anesthesia
889
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...

Endoscopic Studies II: Thoracocentesis
1.8K
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

General Anesthesia: Overview
911
Anesthesia is a medical procedure that uses drugs for CNS suppression to enable painless surgeries and procedures. The selection of anesthetics is influenced by their pharmacokinetic properties, side effects, and patient characteristics. Various types of anesthesia include general, local, regional, spinal, and inhalational.
General anesthesia induces unconsciousness in the whole body, while the others target specific areas or sensations. It is administered to minimize adverse effects, maintain...

Cardiomyopathy VII: Pre and Post Operative Nursing Management
405
Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...

Stages of General Anesthesia
2.0K
Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...
