【摘要】：目的制備一種水凝膠敷料并考察其對SD大鼠深Ⅱ度燒傷創(chuàng)面的愈合作用。方法制備水凝膠敷料,并篩選其滅菌方法。采用新西蘭兔考察其皮膚刺激性。采用熱固體燙傷法制備SD大鼠深Ⅱ度燒傷模型,采用清得佳及長海醫(yī)院院內(nèi)制劑脫痂軟膏為陽性對照,考察水凝膠敷料對其創(chuàng)面愈合作用。結(jié)果制備的水凝膠敷料澄清、透明,黏度與陽性對照藥物清得佳一致。輻射滅菌后,水凝膠敷料黏度急劇下降,高壓蒸汽滅菌前后,黏度無顯著性變化。水凝膠敷料對兔皮膚無顯著刺激性。與清得佳及脫痂軟膏相比,實驗組愈合時間無顯著性差異;與模型對照組相比,愈合時間有顯著性差異(P0.01)。結(jié)論以羥乙基纖維素為基質(zhì)制備的水凝膠敷料,黏度適宜,澄清透明,易于觀察創(chuàng)面愈合情況,無顯著皮膚刺激性,可顯著促進(jìn)SD大鼠深Ⅱ度燒傷創(chuàng)面的愈合,具有廣闊的應(yīng)用前景。
[Abstract]:Objective to prepare a hydrogel dressing and investigate its healing effect on deep second degree burn wounds in SD rats. The skin irritation was investigated by New Zealand rabbit. The SD rat model of deep second degree burn was made by hot solid scald method. Qingdejia and Changhai hospital were used as positive control. The effect of hydrogel dressing on wound healing was investigated. Results the prepared hydrogel dressing was clear and transparent, and the viscosity of hydrogel dressing was consistent with that of the positive control drug. After radiation sterilization, the viscosity of hydrogel dressing decreased sharply. There was no significant change in viscosity before and after high pressure steam sterilization. Hydrogel dressing had no significant irritation on rabbit skin. There was no significant difference in healing time between the experimental group and Qingdejia and descab ointment. Compared with the model control group, the healing time was significantly different (P 0.01). Conclusion the hydrogel dressing prepared with hydroxyethyl cellulose is suitable for viscosity, clear and transparent, and easy to observe wound healing. No significant skin irritation can significantly promote the healing of deep second degree burn wounds in SD rats, which has a broad application prospect.
