摘　　要：目的比较多种泡沫敷料吸、锁水及透气性能，为临床医师针对不同类型创面选用敷料提供参考。方法选择痊愈妥、美皮埭、康惠尔3种临床常用泡沫敷料进行比较。用蒸馏水将8．3gNaCI和0．367gCaCI2·H2O溶解许定容至1L，模拟伤口渗出液（简称渗出液），分别检测：（1）敷料经渗出液浸没24h发水率；（2）敷料存渗出液中浸没1、5、10、20min时吸水速牢；（3）渗出液滴至敷料表面5min后扩敞阿径，以反映敷料锁水性能；（4）敞料密封渗出液24h水蒸发量，以反映其透气忡能。每种敷料每个指标检测5个样本，对数据进行单因素方差分析和冲重复测量设计方差分析，两两比较采用LSD法．结果（1）痊愈妥、美皮康、康惠尔泡沫敷料经渗出液浸没24h的吸水率依次降低．分别为（646±18）％、（616±19）％、（499±11）％（F=423．854，P〈0．01）．敷料间两两比较，差异有统计学意义（P值均小于0．01）。（2）渗出液浸没1、5、10、20min后．痊愈妥泡沫敷料吸水速率分删为（35．20±2．31）、（12．48±0．37）、（6．63±0．23）、（3．39±O．08）g·s-1·m-2．屁若低于荚皮康泡沫敷料的（119．68±2．59）、（24．39±0．62）、（12．33±0．29）、（6．18±O．13）g·s-1·n-2与康惠尔泡沫敷料的（121．09．4-3．41）、（24．73±0．52）、（12．37±0．25）、（6．18±0．13）g-s-1·m-2 P值均小于0．01随着浸没时间的延长，各种敫料的吸水速率均呈明显下降趋势，同种敷料两相邻时相点比较，差异均有统计学意义（P值均小于0．01）。（3）美皮康、康惠尔、痊愈妥泡沫敷料上渗液扩散血伯分圳为（5．66±0．15）、（4．84±0．15）、（3．94±0．21）cm （F=124．742，P〈0．01），敷料间两两比较，差异有统计学意义（P值均小于0．01）。（4）痊愈妥、荚皮康、康惠尔泡沫敷料密封渗出液24h的水蒸发�Objective To compare the proper＇lies of water-absorption, water-locking, and air per- meability among several foam dressings, and to provide references for clinician in choosing dressings for dif- ferent types of wounds. Methods The comparison was made among Allevyn foam dressing, Mepilex foam dressing, and Biatain toam dressing that were eomm±mly used in clinic. NaCI and CaCL ± H,O respectively in the weight of 8.3 g and 0. 367 g were diluted with distilled water to the volume of 1 L to simulate wound exudation. The simulated wound exudation was used to test the water-ahsori±ing rate of dressings at p±st im- mersion hour （PIH） 24, water-absorbing speed of dressings a! post immersion minute （PIM） 1 , 5, I0, anti 20, the diffllsinn diameter o[＂ exudation dripped on the surface of dressings flowr 5 rain to reflect the water-loc- king eapaeit. dressings, and the water evaporatitm capacity of exudation after being sealed tip by dressings flowr 24 h to reflect the stir permeability t±f dressings. Five samples of each dressing were used for each index. Data were processed with one-way analysis of variance and analysis of variance of repeated measurement, and LSD method was applied in paired comparison. Results （ I ） The waler-absorhing rate at P1H 24 of AI- lev.vn foam dressing, Mepilex flJam dressing, and Biatain foam dressing were respectively （646 ± 18）% ,（616 ±19 ） % , and （499 ± 11 ） % （ F = 423. 854, P 〈 0.01 ）. The differences between each two dressings in water-absorbing rate were statistically significant （ with P values all below 0.01 ）. （2） The water-absorb- ing speed of Allevyn foam dressing at PIM 1, 5, 10, and 20 were （35.20 ±2.31）, （12.48 ±0.37）, （6.63 ±0.23）, and （3.39±0.08） g· s-1 · m-2, which were obviously lower than those of Mepilex foam dressing [ （119.68 ±2.59）, （24.39 ±0.62）, （12.33 ±0.29）, and （6.18±0.13） g ± s-1 ± m-2 and Biatainfoam dressing [（121.09±3.41）, （24.73±0.52）, （12.37±0.25）, �
