RESUMEN
Objective To analyze the difference of the peripherally inserted central venous catheter (PICC) and central venous catheter (CVC) in cancer chemotherapy.Methods All eligible studies on PICC and CVC were searched in China National Knowledge Infrastructure,Wanfang database and VIP database.The Jadad scale was used for quality assessment of all the included studies.All analysis were conducted in Stata 12.0.Results Thirty-six studies with a total of 4920 cases of patients were included in this meta-analysis,with 2349 cases in PICC group and 2571 cases in CVC group.PICC group had advantages in puncture success rate for the first time,the average puncture time,the average catheter time than the CVC group.PICC group had fewer complication,such as the hemopneumothorax incidence,the strayed artery incidence and catheter infection incidence; however,the phlebitis incidence was higher than the CVC group.Conclusions PICC has some advantages specific in simple operation,a long retention time,fewer complications and safety.Therefore,PICC can be widely used in cancer chemotherapy.
