Application effect of measuring central venous pressure with different catheter in LBWIs

Objective To discuss the effect of measuring central venous with peripherally inserted central catheter (PICC) in low birth weight infants (LBWIs). Methods Totally 100 LBWIs admitted in the intensive care unit (ICU) of a tertiary hospital from January to Octomber 2015 were selected and were randomly divided into the PICC group and the central venous catheterization (CVC) group, with 50 cases in each group. Patients in the PICC group received the main intravenous catheter, while patients in the CVC group received subclavian intravenous catheter. Data were collected for statistical analysis. The difference of central venous pressure and the incidence rate of complications in patients with different measure methods were compared between two groups. Results The central venous pressure of LBWIs in the PICC group was (8.26±2.18) cmH2O, and in the CVC group was (7.85±2.36) cmH2O (t=0.421, P>0.05); the incidence rates of catheter obstruction, phlebitis and puncture point bleeding of the PICC group were lower than that of the CVC group (χ2=5.01, 6.93, 4.00; P<0.05). Conclusions PICC catheter measurement won′t affect the measure results of central venous pressure in LBWIs, and can reduce the incidence of complications related with central venous catheter in very low LBWIs, so it can be popularized for use.
