概括
甲型玻尿素毒素 (BoNT-A) 在慢性腰部疼痛 (CLBP) 中没有显示出比安慰剂的短期益处. 需要进一步的研究来确认它在改善疼痛和功能方面的有效性.
科学领域:
- 整形外科 整形外科 整形外科
- 疼痛管理 疼痛管理
- 神经学 神经学
背景情况:
- 腰部疼痛 (LBP) 是由骨科外科医生管理的常见疾病.
- 副脊柱肌肉度有助于LBP.
- 毒素A型 (BoNT-A) 可能通过放松肌肉来缓解LBP,但有限的RCT支持其用于LBP.
研究的目的:
- 评估BoNT-A治疗慢性腰痛 (CLBP) 的安全性和有效性.
- 评估BoNT-A对CLBP患者疼痛减轻和功能结果的影响.
主要方法:
- 一项随机临床试验 (RCT) 涉及18至60岁的成年人,他们患有机械性LBP至少六个月.
- 参与者接受了200个伊普森单位的BoNT-A或安慰剂.
- 疼痛 (VAS) 和残疾 (ODI) 在2个月的随访期间进行了评估.
主要成果:
- 在40名参与者中,36名参与者注意到临床显著的疼痛减轻 (50%).
- 两组患者在治疗后的VAS和ODI分数都呈现出统计学上显著的下降.
- 然而,只有ODI得分的变化在群体之间具有统计学意义 (P=0.012),而不是VAS得分 (P=0.45).
结论:
- 在改善CLBP患者的疼痛或残疾分数方面,BoNT-A没有显示出与安慰剂相比的短期优势.
- 该研究表明,与安慰剂相比,BoNT-A不是对CLBP的优越短期治疗方法.

Skeletal Muscle Relaxants: Therapeutic Uses
475
Skeletal muscle relaxants are used to relax muscle tone and alleviate painful muscle contractions. However, the choice of skeletal muscle relaxants depends on the duration of the surgical procedure in order to minimize potential side effects. Skeletal muscle relaxants like neuromuscular blocking agents [NMBAs] are commonly employed as adjuvants alongside general anesthetics in clinical settings. NMBAs are also used to maintain controlled ventilation during surgery of the larynx or pharynx...

Directly Acting Muscle Relaxants: Dantrolene and Botulinum Toxin
660
Directly acting muscle relaxants like dantrolene and botulinum toxin (BoNT) have distinct mechanisms and applications. Dantrolene, a hydantoin derivative, acts on the ryanodine receptor (RYR1) in skeletal muscle cells. RYR1 are calcium channels present at the sarcoplasmic reticulum membrane. In response to excitation, they release calcium ions from the sarcoplasmic reticulum to the cytosol. Calcium promotes actin-myosin-mediated contraction of muscles.

Local Anesthetics: Clinical Application as Spinal Anesthesia
591
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...

Classification of Skeletal Muscle Relaxants
2.4K
Skeletal muscle relaxants are a group of drugs that can reduce muscle stiffness and induce temporary paralysis to relieve pain. These agents can act centrally to reduce muscle tone or spasms in painful conditions such as multiple sclerosis (MS), amyotrophic lateral sclerosis (ALS), or spinal injuries; they are called antispasmodics or spasmolytics.
