两种减压床垫预防心外ICU术后患者压疮的效果比较

Comparing the effect of two types of alternating pressure air mattresses on hospital-acquired pressure ulcers among ICU patients in department of cardiac surgery

目的预防心外ICU术后患者发生压疮,为临床减压床垫选择提供依据。方法将心外ICU 160例术后患者随机分为观察组和对照组各80例,对照组使用交替式减压床垫,观察组使用自动压力交替床垫,其他护理措施相同,观察术后住ICU期间压疮发生率和分期。结果对照组压疮发生率(16.25%)显著高于观察组(5.00%)(P<0.05)。结论自动压力交替减压床垫预防压疮效果优于交替式减压床垫。

Objective To evaluate and compare the effects of two types of alternating pressure air mattresses（APAM）on the incidence of hospital-acquired pressure ulcers（HAPU）among ICU patients in department of cardiac surgery,and to provide a reference for choosing a suitable mattress in clinical practice.Methods A total of 160 cardiac surgical patients were randomized into an experimental and a control group,each of 80.The control group were lying on an APAM after cardiac surgery,while the experimental group were lying on an automatically pressure adjusting APAM（Pro-care Auto,Apex Medical Corp）.The other nursing care and interventions were identical in both groups.Both groups were then observed for HAPU incidences and stages during their ICU stay periods after surgery.Results There were significantly higher incidence of HAPU in the control group（16.25%）than that of the experimental group（5.00%）（P〈0.05）.Conclusion Automatically pressure adjusting APAM were more effective than APAM in preventing pressure ulcers.
