ABSTRACT
Objective To evaluate the clinical effectiveness of venipuncture using the fluorescent intravenous indwelling catheter in dark environment in dog experiments. Methods Six dogs were randomly divided into three groups of two dogs each, and each dog was subjected to 40 times of venipuncture performed on a foreleg with normal intravenous indwelling catheter and fluorescent intravenous indwelling catheter, respectively, under high(101 -105 lux), moderate (10.2-100 lux)or low(5 -10 lux)brightness conditions. The success rates and time consumption of those two procedures were analyzed and compared statistically. Results The success rate and time consumption for venipuncture using fluorescent and normal intravenous indwelling catheter under low brightness were 82.5% and(204.36 ± 13.13)s vs. 40.0% and(249.35 ± 17.98)s, those performed under moderate(simulating morning and dawn)brightness were 90.0% and(194.86 ± 8.60)s vs. 67.5% and(206.37 ± 9.70)s, all showed a significantly higher efficiency of the venipuncture using fluorescent intravenous indwelling catheter(P < 0.05). Conclusions The use of fluorescent intravenous indwelling catheter has the advantages of higher success rate and shorter time consumption for venipuncture under low and moderate brightness conditions.
ABSTRACT
Objective To explore effect of two methods for treating extravasation of venous indwelling needles.Methods A total of 96 patients with extravasation at transfusion were randomly divided into experiment and control groups with 48 cases in each group. Magnesium sulfate wet packing was used in the control group and external application of potato chips in the experiment group.The two groups were compared in terms of time for curative effect to occur and time for recovery.Result The time for curative effect to occur and time for recovery in the experiment group were both significantly shorter than those of the control group.Conclusion External application of potato chips is effective in reducing extravasation during venous transfusion.It is simple and free from side effects.
