RESUMEN
Objective To study effects of palm pressing peripherally inserted untral catheter(PICC) and mandible-pressing-on-shoulder on PICC′s misplacement in jugular veins during intubation. Methods Seventy-six patients undergoing intubation with PICC were randomized into observation group and control group equally by random digital table. The palm pressing PICC method was used in the observation group and the mandible-pressing-on-shoulder method was used in the control group. The two groups were compared in terms of the incidence of PICC misplacement. Result The misplacement rate of PICC in the experiment group was significantly lower than that in control group (P<0.01). Conclusion Palm pressing method is much effective in prevention of PICC misplacement in jugular veins and worth promoting especially in hospitals of basic level.
RESUMEN
Objective To probe into the clinic effect of folded infusion tube which can produce negative pressure on increasing the success rate of infants' scalp venepuncture. Methods 200 infant patients were divided into the control group and the observation group with 100 cases in each group. The control group used routine venepuncture method, while folded infusion tubes are used in the obser-ration group. The end of infusion tubes were folded by 0.5 cm and clamped well. When the needle has been punctured under an infant patient's scalp, the clamp could be loosed so that there was a little neg-ative pressure in the tube. Then the situation of natural revehent blood and success rate of scalp venepuncture were observed in the two groups. Results Rate of natural revehent blood in the control group was 72%, and success rate of scalp venepuncture was 87%. Rate of natural revehent blood in the observation group was 97%, and success rate of scalp venepuncture was 97%. Rate of natural revehent blood and success rate of scalp venepuncture in the observation group were both higher than those of the control group. Conclusions Folded infusion tube can immediately judge whether the needle is punctured inside the blood vessel and effectively increase the success rate of scalp venepuncture.
