中频脉冲电疗法治疗经外周静脉置入中心静脉置管致静脉炎的疗效观察

目的：探讨中频脉冲电疗法治疗经外周静脉置入中心静脉导管（peripherally inserted central catheter，PICC）所致静脉炎的效果。方法：将90例PICC致静脉炎的患者采用随机数字表法分为3组，每组30例, A组给予中频脉冲电疗法，B组给予康惠尔透明贴疗法，C组给予湿热敷疗法，观察患者在治疗第3天、5天、7天后疼痛与肿胀缓解情况、治愈率情况。结果：3组疗法治疗第3天、5天、7天后疼痛缓解程度比较；治疗5天、7天后肿胀缓解程度比较；治疗7天后治愈率比较均示A组治疗明显优于B、C组治疗（P均〈0.05，P〈0.01）。结论：中频脉冲电疗法治疗PICC致静脉炎能尽早地减轻患者局部疼痛、肿胀，治愈率明显优于康惠尔透明贴法与湿热敷法，值得临床开展与推广。

Effects of intermediate frequency pulse electric therapy on phlebitis caused by PICC

AIM：To explore the effect of intermediate frequency pulse electric therapy on Phlebitis caused by peripherally inserted central catheter（PICC）.METHODS：Ninety cases of phlebitis caused by PICC were randomly divided into 3 groups（group A,B and C,n=30）.Group A,B and C were treated by intermediate frequency pulse electric therapy,Kang whirlpool posted therapy and moist heat therapy respectively.The degree of pain,swelling and the cure rate were observed on the 3rd day,5th day and 7th day after treatment.RESULTS：The reduced level of pain among the three groups on the 3rd day,5th day and 7th day was statistically significant（P〈0.01for all）.The difference of the eliminated degree of swelling on the 5th day and 7th day was statistically significant（P0.01）.The cure rate was statistically significant different on the 7th day.The better effect of the treatment was observed in group A comparing with group B or C（P〈0.01）,but there was no obvious difference between group B and C（P〉0.05）.CONCLUSION：The intermediate frequency pulse electric therapy is effective in alleviating local pain and swelling,and shows a better effect in the treatment of phlebitis caused by PICC than kang whirlpool transparent stickers or moist heat,and this method is worthly being recommended in the clinical application.
