摘要目的 观察两种不同折叠方式的纱布在外周静脉穿刺置入中心静脉导管(PICC)置管后局部止血的效果.方法 将152例患者按PICC置管日期先后分为对照组72例和研究组80例,对照组采用约2 cm×2 cm小纱块压迫穿刺点,研究组采取自制的约1.0 cm×1.5 cm无菌纱球压迫穿刺点,观察两组患者PICC穿刺点渗血情况.结果 研究组止血效果优于对照组(x2=15.88,P＜0.01),研究组均未发生肢体肿胀(x2=58.064,P＜0.01).两组止血效果比较差异有统计学意义.结论 采用自制无菌纱球点状压迫止血效果好,又不影响肢体的血液循环.

abstractsObjective To observe the effects of two different gauze folding patterns used in local hemostasis after peripherally inserted central catheters (PICC).Methods A total of 152 patients were selected and divided into two groups according to PICC date sequence as control group of 72 patients using 2.0 cm× 2.0 cm little gauze to oppress the puncture point and observation group of 80 patients using 1.0 cm× 1.5 cm gauze ball made by ourselves to oppress the puncture point.The oozing of the puncture point was observed in patients of the two groups.Results The hemostasis was better in the observation group than in the control group (x2=15.88,P＜0.01).No limb swelling happened to the patients in the observation group (x2=58.064,P＜0.01).There was statistically significant difference in hemostatic effect between the two groups.Conclusion The sterile gauze ball made by ourselves has a good effect on local hemostasis through oppressing the puncture point without any impact on blood circulation of limbs.
