Clinical observation on limb elevation for prevention of blood spills during withdrawal of trocar puncture core needles

ObjectiveThe study aimed to explore a lien secure trocar as an effective method to prevent blood spills.MethodsThis study included 1200 patients, who had a safety catheter from March to April in 2012, from the emergency department of the Shengjing Hospital of China Medical University. The patients were randomly divided into an experimental group and a control group. Using a conventional method, we compressed the vein at the tip of catheter to prevent blood spillage in the control group. We raised the patient's upper limb, while compressing the vein at the tip of catheter in the experimental group.ResultsThe results showed that the experimental group was better than the control group not only in quantity but also in quality regarding blood pollution. The results reached a level of statistical significance (P < 0.01).ConclusionsRaising the patient's upper limb and occluding the vein distal to the catheter can effectively interrupt blood spillage while withdrawing the steel needle (i.e., pulling out the trocar)
