Objective To make an individualized administration scheme via evidence-based medicine methods, namely adding heparin into the total nutrient admixture (TNA) solution, so as to help a neonate to prevent the occlusion of peripherally inserted central catheter (PICC). Methods After carefully assessing the condition of neonate, this clinical issue was put forward in accordance with the PICO principles. Randomized controlled trials (RCTs) and systematic reviews on neonates’ PICC occlusion were collected from The Cochrane Library, CCTR, DARE, NGC, MEDLINE (Ovid) and CBM from inception to 2011. The clinical intervention scheme was finally made after the assessment of the retrieved evidence and neonate’s physiological condition. Results A total of 4 RCTs and 1 systematic review related to the issues were identified. The following scheme was finally made for the neonate through the assessment of the retrieved evidence and combination of intentions of the patient’s family members: heparin (0.5 U/mL) was added into TNA to prevent PICC occlusion. During the application, blood routine test and blood coagulation were monitored, and the catheter opening time and extubation reason were recorded. Through the above treatment, the neonate successfully completed the treatment before extubation. The time of both PICC detaining and opening was 20 days in total, and there were no PICC occlusion, no catheter thrombosis, and no catheter related bloodstream infection. Moreover, no observation showed thrombopenia and aggravated coagulation disorders resulted from heparin. Conclusion The evidence-based medicine method is an effective way to make reasonable heparin scheme for neonate, so as to prevent PICC occlusion, reduce catheter thrombosis, decrease risks of catheter related blood circulation infection, assure successful completion of treatment, and guarantee the safety of patients.

ObjectiveTo investigate the application value of the intravenous indwelling needle in radionuclide imaging examination. MethodsA total of 120 patients underwent single photon emission computed tomography for bone and kidney dynamic imaging between October 2012 and April 2013 were randomly divided into group injected by venous indwelling needle (observagtion group) and group injected by traditional steel needle (control group), with 60 cases in each. We calculated the one-time success rate of venipuncture, the leakage rate of intravenous injection, residual radioactive dosage within the syringe and average exposure time of medical staff to radionuclide in the two groups of patients. ResultsThe one-time success rate of venipuncture in observation group was similar to that in the control group (P > 0.05). During the injection, no leakage was found in observation group, while 4 leakage in 37 patients underwent bone imaging and 3 leakage in 23 patients underwent kidney dynamic imaging in the control group were found; there was no significant difference between the two groups (P > 0.05). The residual radioactive dosage within the syringe in observation group was lower than that in the control group, and the exposure time of medical staff to radionuclide in observation group was also lower than that in the control group (P < 0.01). ConclusionsIntravenous indwelling needle for venous puncture can avoid leakage of radioactive imaging agent, reduce the residual radiological dosage within the syrings, increase the one-time puncture success rate and imaging resolution of dynamic scan, and improve the diagnostic accuracy and work efficiency effectively. Besides, the intravenous indwelling needle technique can reduce average exposure time of medical staff to radionuclide, acheaving the goal of optimized protection.
ObjectiveTo observe the clinical efficacy of non-nutritional sucking and 10% glucose water plus non-nutritional sucking in relieving the venipuncture pain for premature infants. MethodA total of 167 premature infants between April and December 2014 were selected as our study subjects, and they were randomly divided into three groups:intervention group Ⅰ (n=53), intervention group Ⅱ (n=58), and the control group (without any intervention, n=56). Two minutes before venous indwelling needle puncture, blood oxygen saturation and heart rate of the infants were recorded during their quiet state. In the process of venipuncture, the intervention group Ⅰ was given non-nutritional sucking, intervention group Ⅱ was given 10% glucose water plus non-nutritional sucking, and the control group did not accept any intervention. Premature pain rating scale (PIPP) was used to compare the three groups of infants in terms of pain score, heart rate and blood oxygen saturation 1 minute and 5 minutes after intravenous indwelling needle puncture. SPSS 17.0 software was applied for statistical analysis. ResultsOf the 167 premature infants, one-time puncture was successful in 152 infants, with 46 in intervention group Ⅰ, 54 in intervention group Ⅱ, and 52 in control group. One minute after intravenous indwelling needle puncture, PIPP score of intervention group Ⅰ and Ⅱ was significantly lower than that of the control group (P<0.05). The PIPP score of intervention group Ⅱ was significantly lower than that of intervention group Ⅰ (P<0.05). One minute and 5 minutes after intravenous indwelling needle puncture, heart rate in the intervention groups was significantly lower than that in the control group (P<0.05), blood oxygen saturation in the intervention groups was signficantly higher than that in the control group (P<0.05), and they were significantly lower in intervention group Ⅱ than in intervention group Ⅰ (P<0.05). ConclusionsNon-nutritional sucking is effective in alleviating venipuncture pain for premature infants, especially when it is used together with 10% glucose water. The method is worthy of clinical promotion.
ObjectiveTo systematically review the effectiveness and safety of anatomic landmarks positioning method (ALM) and real-time two-dimensional ultrasound (RTUS) guidance in the internal jugular vein cannulation. MethodsWe searched PubMed, EMbase, Web of Knowledge, CBM, WanFang Data and CNKI for randomized controlled trials (RCTs) concerning the effectiveness and safety of ALM and RTUS in the internal jugular vein catheterization up to May 1st, 2014. According to the inclusion and exclusion criteria, two reviewers independently screened literature, extracted data, and assess methodological quality of included studies. Then meta-analysis was performed using RevMan 5.3 software. ResultsA total of 10 RCTs involving 1 973 cases were included in the metaanalysis. The results of meta-analysis showed that, compared with the ALM method, the RTUS method reduced puncture failure rate (OR=0.08, 95%CI 0.05 to 0.15, P<0.000 01). For safety, compared with the ALM method, the RTUS method was significantly lower in arterial injury rate (peto-OR=0.22, 95%CI 0.14 to 0.37, P<0.000 01), and the incidence of pneumothorax (peto-OR=0.13, 95%CI 0.04 to 0.40, P=0.000 3). ConclusionCompared to the ALM method, the RTUS method has characteristics such as causing fewer traumas, and having higher success rate and fewer complications. Due to limited quantity and quality of the included studies, the above conclusion still needs to be verified by conducting more studies.
ObjectiveTo systematically evaluate the efficacy and safety of anatomical landmark method (ALM) versus ultrasound (US)-guided internal jugular vein (IJV) catheterization in pediatric patients. MethodsDatabases including PubMed, EMbase, The Cochrane Library (Issue 10, 2016), CNKI, CBM, WanFang Data and CNKI were searched from inception to October 2016 to collect randomized controlled trials (RCTs) of landmark-guided versus ultrasound-guided IJV catheterization in pediatric patients who underwent elective surgery. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Then RevMan 5.3 software was used to perform meta-analysis. ResultsA total of 13 RCTs involving 1 026 pediatric patients were included. The results of meta-analysis showed that, the overall success rate (RR=1.21, 95%CI 1.09 to 1.34, P=0.000 5) and arterial puncture rate (RR=0.19, 95%CI 0.07 to 0.50, P=0.000 7) of US-guided IJV catheterization were both significantly superior to the ALM group. Whereas there was no significant difference between two groups as for the incidence of hematoma formation (RR=0.35, 95%CI 0.09 to 1.31, P=0.12). ConclusionCurrent evidence shows that, for IJV catheterization of pediatric patients, both the effectiveness and safety of ultrasound-guided technique are better than the landmark-guided. Since the quantity and quality of included studies are limited, the conclusion of this study needs more high quality studies to verify.
