Effects of Upper Arm Placement of Peripherally Inserted Central Catheters with SiteRite5 Vascular Ultrasound Guidance System and Microintroducer Technique

Objective To observe the effects of peripherally inserted central catheters(PICC) puncture by using SiteRite5 vascular ultrasound guidance system and microintroducer technique.Methods A total of 139 PICC patients from January to November,2009 were divided into the observational group(N=72) and control group(N=67) based on admission sequence.The status of target vessels of the observational group were evaluated with Bard SiteRite5 vascular ultrasound guidance system and then microintroducer technique was used in PICC puncture of the upper arm.The patients of the control group were treated with PICC puncture using normal vascular ultrasound machine.The differences in the one-time success rate and the overall success rate of the puncture,the potential complication and the comfort status were compared between the two groups.Results The one-time success rate and the total success rate reached 97.2% and 100% respectively.After the operation,none of the cases was found with mechanical phlebitis,deep vein thrombosis or local infection.The difference had statistical significance between two groups after therapy(P0.01).Significant difference in PICC puncture pain was observed in the patients of the two groups(P0.01).Conclusion The PICC puncture using SiteRite5 vascular ultrasound guidance system and microintroducer techniques can provide a safe minimal invasive surgery with higher one-time success puncturing rate,lower rate of complications and fewer pains,which has wider clinical applications.
