概括
在剖腹产期间常规的左侧倾斜在使用预防性血管压缩剂时是不必要的. 这种做法不会减少血管压缩剂的需求或改善新生儿的结果,允许个性化的患者定位.
科学领域:
- 麻醉学 麻醉学
- 产科 产科 产科 产科 产科
- 孕产妇和胎儿医学 孕产妇和胎儿医学
背景情况:
- 传统上,建议在剖腹产期间进行左侧倾斜,以防止动脉腔压缩并保持血液动力学稳定性.
- 随着目前的预防性血管压缩剂策略,常规倾斜的有效性是可疑的,需要进一步调查.
研究的目的:
- 为了评估左侧倾斜在剖腹产中增加的好处,当预防性血管压缩剂被管理.
- 为了确定左侧倾斜是否会影响母亲的血液动力学稳定性或新生儿的结果.
主要方法:
- 一项前性,非随机的观察性研究包括99名在脊髓麻醉下接受选择性剖腹产的妇女.
- 参与者被分配到一个标准的15°左侧倾斜或一个平坦的仰卧姿势.
- 使用预防性上腺素输注,定位以保持缩血压在基线的90-100%;主要结局是平均上腺素输注速率.
主要成果:
- 在倾斜和不倾斜组之间没有观察到中位数诺亚上腺素输注速率的显著差异 (两者均为0.03μg/kg/min).
- 群体之间,每公斤上腺素总剂量和正常化剂量是可比的.
- 新生儿结局,包括Apgar分数和动脉血气参数,没有显著差异.
结论:
- 15°左右的横向倾斜不会减少血管压缩剂的需求,也不会提高剖腹产产后新生儿的预后结果.
- 在这种情况下,对于血液动力学优化而言,常规的母体倾斜似乎是不必要的.
- 可以使用个性化患者定位,而不会影响母亲或新生儿的安全.

Local Anesthetics: Clinical Application as Epidural Anesthesia
682
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...
