ObjectiveTo investigate the clinical effect of No. 8 blood collection needles in connecting broken balloon tubes. MethodsThirty-six patients who underwent mechanical ventilation in the Intensive Care Unit between January 2010 and December 2013 were included as the study subjects. We divided them into two groups. Patients who had accidental rupture of balloon tube during intubation were regarded as the trial group, while those with normal ventilation were regarded as the control group, with each group having 18 patients. The trial group used No. 8 disposable blood collection needles to connect the balloon tubes. Pressure gauge produced in Germany was used to measure the balloon pressure continuously for four hours. Balloon pressure level, balloon leakage and tube dislocation within 24 hours were observed. ResultsThe balloon pressure at different time periods was not significantly different between the two groups (P > 0.05). The leakage rate and complication rate were also not significantly different between the two groups (P > 0.05). ConclusionsUsing No. 8 blood collection needles for connecting broken balloon tubes is effective, easy, and convenient, and the balloon can be maintained at a constant pressure. It solved many previous clinical problems such as high cost, high complication rate, high death rate and medical disputes.
Objective To evaluate the effect and safety of infantile femoral vein blood sampling with vacuum versus disposable needle. Methods Such databases as VIP, CNKI, CBM, Google Academic and Wanfang data were searched to collect the randomized controlled trials (RCTs) about infantile femoral vein blood sampling with vacuum versus disposable needle published from January 2000 to July 2010. The studies were screened according to the inclusive and exclusive criteria, the data were extracted, the methodology quality was assessed, and meta-analysis was conducted by using RevMan 5.0 software. Results A total of 15 RCTs were included. Of 3 490 patients in all, 1 770 were in the treatment group and 1 726 were in the control group. The baseline conditions were reported in 14 studies, and the random methods were mentioned in 11 RCTs. All studies didn’t report the allocation concealment and blind method. Only 2 RCTs reported separately that, the degree of neonatal pain was lower in the treatment group (Plt;0.01), and the satisfaction of parents was higher in the treatment group (Plt;0.01). Four RCTs compared the sampling time between the two groups without meta-analysis mentioned due to the disunity of standard, only the descriptive outcomes showed a shorter time in the treatment group. The meta-analysis showed that, compared with the control group, the reject rate of sample quality was lower (RR=0.20, 95%CI 0.15 to 0.26), the success rate of one time sampling was higher (RR=1.20, 95%CI 1.16 to 1.24), the injury of local tissue was slighter (RR=0.62, 95%CI 0.45 to 0.86), and the iatrogenic contamination was lower (RR=0.62, 95%CI 0.45 to 0.86) in the treatment group. Conclusion This review shows that the vacuum sampling is superior to the disposable needle sampling for domestic infantile femoral vein blood collection. Due to the low quality of the included studies with high possibility of bias, this conclusion needs to be further verified by performing more high-quality studies.
