OBJECTIVETo explore the improvement the dingle technology through the PICC catheter puncture point elbow hemostatic effect. Selection.

METHODSBetween January 2013 and December 2013, chest hospital affiliated to Shanghai jiaotong university under the guidance of ultrasound improved the Ding Gehang PICC catheter patients of 997 cases were randomly divided into three groups A, B, C, respectively, using gauze pad, calcium alginate wound dressings, calcium alginate wound dressings with hemostatic gauze pad three methods to puncture point, compare the three groups within 48 h after puncture biopsy in patients with some local bleeding, treatment times and catheter after 1 week of the maintenance costs of the catheter.

RESULTSCompared with A, B two groups, patients of group C tube after 48 hours the puncture point local oppression hemostasis effect is better than that of group A and B, the difference was statistically significant (all P < 0.05); Catheter maintenance: group C within 1 week after catheter tube after local lowest maintenance cost.

CONCLUSIONPICC for surgery after the puncture point of oppression hemostasis method choice, the effect of calcium alginate dressings hemostatic gauze pad is better than that of gauze pads and calcium alginate dressings, calcium alginate dressings and gauze pad is more effective and economic, in clinical use.
