  • Influence of PICC Ultrasound Guidance on Elbow Puncture and Catheterization and Its Complications: A Systematic Review

    Objective To systematically evaluate the influence of PICC (peripherally inserted central catheter) ultrasound guidance on success rates and incidences of complications of elbow catheterization. Methods The Cochrane Library (Issue 3, 2012), Library of JBI evidence-based nursing center, MEDLINE, EMbase, CBM, VIP, CNKI and WanFang Data were searched for relevant studies to influence on success rates of puncture and catheterization and complications from upper arm placement of PICC ultrasound guidance as well as conventional PICC placement from inception to March, 2012. The data were extracted according to the inclusion and exclusion criteria by two reviewers, the quality of included studies was also evaluated. Meta-analysis was conducted using RevMan 5.1, or only descriptive analysis was conducted instead. Results Eleven randomized controlled trials, five clinical controlled trials and four cohort studies were included, involving 4 052 patients. The results of meta-analysis showed that, upper arm placement of PICC ultrasound guidance combined with modified Seldinger technique was associated with significantly higher one-time success rates of puncture and catheterization than conventional PICC placement below the elbow, with significant differences (OR=4.71, 95%CI 1.97 to 11.28, P=0.000 5; OR=8.63, 95%CI 1.92 to 38.82, P=0.005). Conventional elbow catheterization had a significantly higher incidence of phlebitis than catheterization on the elbow that under the guidance of PICC ultrasound and modified Seldinger technique (OR=0.13, 95%CI 0.08 to 0.21, Plt;0.000 01). Conclusion Elbow catheterization under the guidance of PICC ultrasound combined with modified Seldinger technique has an obvious advantage in improving the success rates of puncture and catheterization and reducing the incidence of complications, compared with conventional elbow catheterization.

  • Efficacy of Comfort Care on Patients Undergoing CT Enhanced Scan

    ObjectiveTo explore the effect of comfort care on patients undergoing CT enhanced scan. MethodsSixty patients undergoing CT enhanced scan were enrolled in June 2013, who were randomly divided into general care group (n=30) and comfort care group (n=30). General care group was given the routine care, while patients in the comfort care group accepted comfort care as well as routine care. The success rate of examination and excellent or good imaging rate between the two groups were compared. ResultsIn the general care group, the scan was successful in 21 patients and failed in 9, with a successful scan rate of 70.0% (21/30), and the excellent and good imaging rate was 71.4%. For the comfort care group, the scan examination succeeded in 29 patients and failed in 1 with a success rate of 96.7% (29/30), and the excellent and good imaging rate was 96.6% (28/29). The success rate in the two groups had statistical significance (χ2=7.680, P=0.006), and the excellent and good imaging rate was also significantly different (χ2=7.607, P=0.022). ConclusionComfort care for patients undergoing CT enhanced scan has a good effect in alleviating psychological stress, ensuring comfort and safety, and improving the success rate and excellent and good rate of imaging quality, which reflects its real value of nursing service in CT Department.
