Meta analysis of the application of ultrasound-guided for the vein catheterization in infants

Abstract

Objective To systematically evaluate the difference between ultrasound-guided and traditional body surface localization for the vein catheterization in infants .Methods Cochrane library , PubMed, Highwire, EMbase, China biomedical literature databases （CBM）, CNKI and so on were searched.The randomized clinical trials of ultrasound-guided and traditional body surface localization for the vein catheterization in infants were collected .The date of retrieval documents is from January 1993 to January 2013 . The evaluation method of Cochrane system was used , and the research objects were chosen according to the inclusion and exclusion criteria .The effective data were analyzed by RevMan 5.0 software through Meta analysis.Results Six randomized controlled clinical studies （319 cases） in which the ultrasound-guided and traditional body surface localization for the vein catheterizations in infants were used were chosen .The results showed that in the ultrasound-guided group the time was shorter [ WMD =-6.10, 95%CI （ -8.10 --4.10）],and the successful rate of puncture was higher [WMD=5.06, 95%CI（2.33-10.97）], and the attempt times of puncture was less [WMD=-1.05, 95%CI （ -1.43--0.68）], and the incidence rate of complication was lower [WMD=0.13, 95%CI （0.55-0.34）].Conclusions On the premise of mastering the use of ultrasonic instrument , the ultrasound-guided for the vein catheterization can shorten the time , and improve the successful rate , and reduce the times of puncture , and decrease the complications compared with the traditional body surface localization .Especially for the cases of difficultly puncturing through the traditional body surface localization , the ultrasound-guided for the vein catheterization has significant advantages , and is worthy of clinical application .
