中心静脉导管在持续腰大池脑脊液引流术中的应用

目的观察中心静脉导管在持续腰大池脑脊液引流术中的应用效果。方法将86例蛛网膜下腔出血病人被随机分为2组，分别采用硬膜外导管及中心静脉导管进行持续腰大池引流，比较置管术中和术后并发症的发生情况。结果两种导管一次性置管成功率均较高，但在置管过程中均易出现下肢及会阴部异感不适等神经刺激症状，组间比较无显著性差异（P〉0．05）；与硬膜外导管组相比，中心静脉导管组出现引流不畅、导管脱落、感染及脑脊液漏等不良反应明显降低（P〈0．05或P〈0．01）。结论中心静脉管能保证引流通畅，容易控制流速和流量，适合持续腰大池引流术的需要。

Application of central venous catheter in continuing drainage of cerebrospinal fluid from Lumbar cerebellomedllary cistern

Objective To observe the effect of central venous catheter in continuing drainage of cerebrospinal fluid(CSF) from lumbar cerehellomedullary cistern.Methods 86 cases with subarachnoid hemorrhage(SAH) were randomly divided into two groups,43 cases in each group.Epidural catheter and central venous catheter were used in two groups respectively,complications during and after operative were recorded.Results Ievement ratio of placing catheter in both groups was high,nerve irritation of lower limbs and perineal region appeared during placing tuheo there was no difference in between the two groups (P＞0.05).Compared with epidural catheter group,adverse,effect such as inadequate drainage,catheter defluvium,infection and leakage of CSF in central venous catheter group decreased markedly (P＜0.05 or P＜0.01).Conclusions Entral venous catheter can drain CSF smoothly,control flow rate of CSF easily.Central venous catheter can .satisfy continue drainage,of CSF in lumbar cerehellomedullary cistern.
