概括
储存的红细胞年龄会影响正常热区域输液 (NRP) 期间的乳酸水平. 较新的血液制品导致乳糖水平降低,有助于在移植时评估肝脏活力.
科学领域:
- 器官移植 器官移植 器官移植
- 进行心血管外科手术.
- 身体生理学 身体生理学
背景情况:
- 乳酸是正常热区域输液 (NRP) 期间肝脏活力的关键标志物.
- 储存的红细胞 (pRBC) 继续产生乳酸,可能会混NRP乳酸测量.
- 输血的pRBC的年龄可以影响NRP电路中的乳酸水平.
研究的目的:
- 为了研究储存红细胞年龄在NRP期间对乳酸水平的影响.
- 为了确定pRBC年龄是否与NRP透中的乳酸盐度相关.
- 评估肝脏活力评估在循环死亡 (DCD) 后捐赠者的临床影响.
主要方法:
- 对接受NRP的16名DCD捐赠者的前性研究.
- 输血前在pRBC袋中测量的乳酸水平.
- 对NRP电路的连续乳酸测量每15分钟进行一次.
主要成果:
- pRBC乳酸水平在4.4 mmol/L至>20 mmol/L之间,与血液年龄有很强的相关性 (r2 = 0.74).
- 接受较新的PRBC (到期后≥20天) 的捐赠者与接受较旧的PRBC (到期后<20天) 的捐赠者相比,60分钟NRP乳酸显著降低 (4.0±2.0 mg/dL对比6.3±2.3 mg/dL;p=0.048).
结论:
- 储存红细胞的年龄是NRP期间影响乳酸水平的重要因素.
- 临床医生应该考虑较旧的PRBC输血作为乳酸水平不下降的潜在原因.
- 在仅基于乳酸趋势的肝脏衰退之前,可能需要进一步的乳酸评估或延长输液 (NRP/NMP).

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
2.2K
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.

Factors Affecting Drug Distribution: Organ Perfusion Rate
827
Drug distribution within the body is a complex process influenced by several factors, including perfusion rate, the rate at which the bloodstream transports drugs to tissue. This limitation becomes particularly significant when dealing with highly lipophilic drugs. In such cases, the rate at which the drug can move across membranes is crucial, and if the membrane is highly permeable to the drug, distribution becomes rate-limited by perfusion.
