Abstract:
Objective To explore the timing of local anesthesia in ultrasound-guided modified Seldinger technique PICC puncture, so as to provide theoretical basis for formulating unified operating standards in clinic. Methods Totals of 128 patients with PICC after operation were randomly divided into pre-anesthesia group and post-anesthesia group (64 cases in each group).In pre-anesthesia group, 0.2 ml 2%lidocaine was injected in the puncture point before puncturing; in post-anesthesia group, 0.2 ml 2% lidocaine was injected after puncturing.Body pain score in the process of puncturing and times of puncturing were compared between the two groups.Results The body pain score in pre-anesthesia group was (1.64 ±1.58),and (1.64 ±1.21)in post-anesthesia group, the difference was not statistically significant (t=0.00,P>0.05).The times of puncturing in pre-anesthesia group was (1.59 ±1.35), which higher than (1.18 ±0.50) in post-anesthesia group, and the difference was statistically significant (t=2.20,P<0.05).In pre-anesthesia group, the distance from local anesthesia point to the actual piercing point was positively related to pain score (r =0.319,P <0.05). Conclusions The pain were no different caused by local anesthesia before and after piercing, but less piercing times in condition of anesthesia after putting thread in, which can improve the success rate of puncture.
