ABSTRACT BODY

TARGET POINT INJECTION FOR TREATMENT OF LUMBARDISC HERNIATION
Provincial Hospital Of Heilongjiang Di Si HAO
Aim: The purpose of this study was to examine the target point injection on lumbardisc herniation (LDH). This investigation utilized a 2-group.Single- blind experimental design.
Method: In order to be included in this study, all subjects had to have a negative neurological and medical workup in vertebral canal .All of these patients have unilateral pain in lumbar and limb.80 cases were selected ,Male 50, Female 30, age from 20~55 years ,BW 55~65kg,BH 165~175cm, illness duration 6~12 months. All patients were demonstrated by CT in L4,5 or L5,S1 protrude.80 patients were divided into 2 groups average randomly.
Group A After succeeded epidural puncture in L3,4 space, a epidural catheter with a microelectrode was inserted into epidural space 3 cm toward the head. Then connected the stimulator with weak current .When the stimulating was feeling in illness limb, the correct position was demonstrated following 1% xylocaine 10ml contain Triamcinolone Acetonide iTAj 20mg was injected .Group B epidural injection was performed with 1% xylocaine 10 ml contain TA 20 mg. VAS were determined, the pain measure were taken pre and post 10,20,30,60 min..
Results: Group A. excellent 80.3%,good 12.5%, improvement0.5%,failed 0.25%.Group B excellent 63.6%,good14.3%,improvement 10.7%,failed11.4%.P<0.001.The results suggest that target point injection was significantly more then general epidural injection.
Discussion: It was general acknowledged that epidural injection for treatment of LDH but the effect was different may be related to the injection position .Some authors were supervised by X ray ,CT and DSA but too complicate and costly. Target point injection in this study is simply and easily and gained a good effect. We did not design this study to determined the mechanism by which target point exerts itfs analgesic effects. However the finding supports the original explanation proposed by Melzack and based on the Gate Control Theory.
Conclusion: The results presented here indicated that target point injection in epidural space represented a significant effect it is a best selection for LDH.
