目的 :探讨肛管粘膜反射的临床意义。方法 :食指插入肛管 ,向肛外快速抽拉 ,指触到肛管括约肌收缩为反射阳性。观察 :(1 ) 5 0例正常人的肛管粘膜反射 ,(2 ) 38例脊柱脊髓损伤或病变者肛管粘膜反射、肛门反射与球海绵体反射出现时间 ,(3) 2 0例与脊髓无关的腰麻手术者麻醉消退过程中 ,上述 3种反射出现的时间顺序。结果 :正常人肛管粘膜反射检出率 1 0 0 % ;脊髓不完全损伤者肛管粘膜反射恢复时间早于球海绵体反射和肛门反射 ;腰麻后肛管粘膜反射出现的时间平均为 3 5h ,球海绵体反射出现的时间平均为 4 5h ,肛门反射出现的时间平均 5 0h。结论 :肛管粘膜反射检查简便易行 ,可作为脊休克结束、脊髓功能开始恢复的一个标志。
Objective: To investigate the clinical significance of anal canal mucosal reflex. Methods: The index finger was inserted into the anal canal and quickly pulled out to the outside of the anal. The finger was touched and the anal sphincter contracted to be reflexive. Observations were: (1) mucosal reflexes in 50 normal subjects, (2) mucosal reflexes, anorectal reflex and bulbocervical reflex in 38 patients with spinal cord injury or lesions, (3) 20 and spinal cord Unrelated to spinal anesthesia anesthesia subsided during the above three reflections appear in chronological order. Results: The detection rate of mucosal reflex in normal people was 100%. The mucosal reflex recovery time of anus mucosa was earlier than that in spontaneous reflex and anal reflex in patients with incomplete spinal cord injury. 5h, the average time of sponge reflex appears to be 45h, the time of anal reflex appearance 50h. Conclusion: Anal canal mucosa reflex examination is simple and easy, and can be taken as a sign of the end of spinal shock and the recovery of spinal cord function.
