【摘要】 目的探讨应用改良屈肌腱鞘浸润麻醉进行手足指(趾)手术的治疗效果。方法对32例手足指(趾),全部采用改良屈肌腱鞘浸润麻醉进行手术。结果所有病例均经1次注入鞘管成功。麻醉用药剂量单指(趾)平均1.5～3ml。起效时间平均2～3min,持续时间平均2～3h。术中对刷洗、双氧水冲洗、切皮、清创、咬除骨质、缝合等刺激耐受良好,无疼痛感。麻醉范围:拇指(趾)掌指(跖趾)关节以远部分,第2～5指(趾)掌指(跖趾)关节以远部及相邻指(趾)半指(趾),各指(趾)近节背侧效果稍差,拇指(趾)近节背侧几无麻醉作用。结论改良屈肌腱鞘浸润麻醉操作简单、起效迅速、用药经济安全、无任何副作用,特别适用于手足指(趾)手术的麻醉方法。更多还原

【Abstract】 Objective To evaluate the effect of improved flexor tendon sheath infiltration anesthesia in the operations of fingers and toes.Methods 32 cases were operated with flexor tendon sheath infiltration anesthesia.Results 45 digits of 32 cases were all injected into the tendon sheath by one time.The effects were all good.The average dosage of anesthetic was 1.5~3 ml every finger or toe.The average time to get effect was 2~3 minutes and the average duration was 2~3 hours.The stimulation such as scrub,washing with hydrogen peroxide solution,cutting,debriding,dividing bone and suturing were all tolerated.Patients did not feel pain.The bounds of anesthesia:The effective area was distal to metacarpophalangeal joint and half of neighbouring finger(toe).The effect of the back of proximal phalanx was poor.There is almost no effect on the back of proximal phalanx of pollex.Conclusions Improved flexor tendon sheath infiltration anesthesia is a simply-operated anesthetic method.Taking effect is very rapid.It is cost effective and safe,especially suitable for the operations of fingers and toes.更多还原
