Application of the local pre-analgesia on the PICC catheter under the direct vision of site-rite V ultrasonic

Abstract

Objective To explore the analgesic effect of local pre-analgesia on the peripherally inserted central catheter （ PICC ） catheter under the direct vision of site-rite V ultrasonic in order to provide the preemptive analgesia for PICC catheter patients and come true the painless nursing during the PICC catheter . Methods Sixty patients with the PICC catheter under the direct vision of site-rite V ultrasonic combined by the MST technology were chosen and divided into the observation group and the control group according to the random number table , each with 30 cases.The observation group received the subcutaneous local infiltration anesthesia in blood vessels through 0.3 ml of 0.2% lidocaine under the direct vision of site-rite V ultrasonic before the puncture , and the control group received the subcutaneous local infiltration anesthesia through 0.3 ml of 0.2%lidocain after the percutaneous puncture and before the skin expansion .The pain index , the degree of feeling during the PICC catheter in the patients and patients ’ satisfaction were compared between two groups . Results The score of pain during the PICC catheter was （5.29 ±2.89） in the observation group, and was （5.77 ±2.34） in the control group, and the difference was statistically significant （t=-0.710,P〈0.05）. The assessment grade of puncture feeling in the observation group was lower than that of the control group ;and the cases of patients with short sharp pain feeling in the puncture location were 20 cases in the observation group, and were 3 cases in the control group, and the difference was statistically significant （Z=-4.743,P〈0.05）.The patients’ satisfaction was 73.3%in the observation group , and was 53.3% in the control group, and the difference was statistically significant （χ2 =199.00,P〈0.01）.Conclusions The local pre-analgesia under the direct vision of site-rite V ultrasonic during the PICC catheter can accurately and effectively carry out the local anesthesia in the puncture location , and relieve patients ’ pain during the PICC catheter , and improve patients’ comfort, and increase patients ’ satisfaction.
