肛门外括约肌肌力的量化分级在脊髓神经不完全损伤

目的对肛门外括约肌肌力进行量化分级，并探讨其在脊髓神经不完全损伤恢复期的意义。方法肛门内置水囊与KLP－V30型智能生理压力测试仪相联。测量20例腰麻前后的肛门外括约肌自主收缩压直至恢复至麻醉前水平，同时记录双下肢感觉运动评分。并对10例脊髓损伤恢复期患者观测随访。结果腰麻后随着神经功能状态改变，感觉运动评分逐渐提高，肛门外括约肌肌力也存在梯度。将其肌力分为4级，正常肌力在25mmHg左右。临床应用表明脊髓不完全损伤者肛门外括约肌肌力及恢复情况与脊髓损伤及恢复程度有关。结论对肛门括约肌肌力进行量化分级可作为脊髓损伤及其功能恢复程度的一个辅助参考。

Quantitative grade andsignificance of sphincter ani externus myodynamia

Objective To study the quantitative grade of sphincter ani externus myodynamia and to discuss the significance of using in convalescent of incomplete spinal cord injuries.Method A small water sac linked to KLP－ V30 intelligent measure of physiologic pressure was insered in to anal canal.Sphincter ani externus independence systolic pressure of 20 cases was measured from before lumbvar anesthesia to recovery.Meanwhile,both lower extremities sensorimotor score was dicumented.10 cases spinal cord injuries reconvalescent had been follow up .Result With the alteru of nerve functional status aftere lumbar anesthesia,sensorimotor score gradually rose,and sphincter ani externus myodynamia also rose by degrees.Accoding to the trial result,the myodynamia was divided 4 grades.Nomal myodynamia was about 25 mmHg.It was made clear that sphincter ani extermus myodynamia recovery of incomplete spinal cord injuries correlated with degree of spinal cord injuries and recoveries.Conclusion It might take as one reference of evaluation degree of spinal cord injury and its function recovery to make the quantitatvie grade of sphincter ani extermus myodynamia.
