Advantage of B-ultrasound Guidance in Indwelling Needle Puncture of External Jugular Vein for Patients in General ICU

The paper aims to investigate the advantage of B-ultrasound guidance in indwelling needle puncture of external jugular vein in the emergency treatment for critical patients with microcirculation failure. We included 70 microcirculation failure patients induced by different factors and with unclear external jugular veins that were admitted to the general ICU from September 2018 to June 2019 and performed indwelling needle puncture on them. We used random number table to divide the patients into control group and observation group with 35 patients in each group. The control group received traditional indwelling needle puncture and the observation group was given B-ultrasound guided indwelling needle puncture. The success rate, time and cost of indwelling needle puncture of two groups were compared. In the control group, 31 out of 35 cases of indwelling needle puncture were successful. The success rate was 88.6% and the average time consumed in each case was (9.09±2.35) min; in the observation group, 35 out of 35 cases of indwelling needle puncture were successful. The success rate was 100% and the average time consumed in each case was (2.13±0.52) minutes. Statistically, the results of observation group were significantly better than those of the control group (P<0.01). In the emergency treatment for critical patients with microcirculation failure, compared with the doctor-guided central venous catheterization, B-ultrasound guided indwelling needle puncture of the external jugular vein has the advantages of high success rate and time efficiency so as to open the vein access for critical patients quickly and help them take the medicine timely, which reduces the pressure of nurses and is well worth clinical application.
