چکیده
مقدمه:‌ در این مطالعه تاثیر خواص ویژه غیر بیهوشی پروپوفول در بهبود زنده مانی فلپ های پوستی ارزیابی شده است.

روش کار: تعداد 32 سر موش صحرایی ماده بالغ به طور تصادفی به دو گروه تقسیم شدند. در گروه 1 بیهوشی با کتامین  (40 mg/kg) و در گروه 2 بیهوشی با پروپوفول  (100 mg/kg)به صورت داخل پریتونیومی (IP) انجام شد. پوست پشت رت در ابعاد 8 × 5/2 × 8 سانتیمتر تمام ضخامت در سه ضلع برداشته و پایه فلپ حفظ شد. فلپ بلافاصله در محل اولیه بازگردانده شده و با نخ نایلون 0/5 و الگوی ساده‌ تکی بخیه شد. وضعیت ظاهری ترمیم روزانه بررسی شده و با اندازه گیری ابعاد ناحیه نکروزشده و سالم، میزان زنده مانی فلپ پس از عکس­برداری محاسبه گردید. ارزیابی نمونه های هیستوپاتولوژیکاز سه نقطه بالا، وسط و پایین فلپ توسط پاتولوژیست نا آگاه از گروه نمونه ها در زمان های  1، 4، 7 و 21 روز صورت گرفت. ارزیابی میزان اینترلوکین های 1 و 6 در نمونه های خون قبل از ایجاد فلپ و در زمان‌های دوازده، بیست و چهار، و صدوشصت و هشت ساعت متعاقب ایجاد آن صورت گرفت.

یافته ها: درصد زنده مانی فلپ در روز 21 و میزان اینترلوکین 6 در روز صفر، ساعت 12 و روز 1 در گروه پرپوفول به طور معنی داری بیشتر از گروه کتامین بود و فعالیت اینترلوکین 1 تفاوت معنی داری نداشت. در گروه پرپوفول نشانه های ترمیم بیشتر از گروه کتامین مشاهده شد.

نتیجه گیری: به نظر می رسد پروپوفول نقش موثرتری در زنده مانی فلپ پوستی نسبت به کتامین دارد‏ْ‎؛ اما تایید قطعی آن نیاز به مطالعات دقیق تر و کامل تر دارد.

چکیده English

Introduction: Propofl is an anesthetic drug which has shown many other effects in different studies. The purpose of this study has been evaluation of non-anesthetic properties of propofol in skin flap survival in rats.

Materials and methods: Thirty two adult female white rats were randomly divided into two groups. In Group 1, anesthesia with ketamine (40mg/kg) and group 2 anesthesia with propofol (100 mg / kg) was performed intraperitoneally (IP). The skin on the back of rats (2.5 × 8 × 8 cm) was prepared aseptically. Full-thickness skin was removed in three parts and returned to the original location immediately. The skin was sutured with single interrupted pattern and nylon 0/5. Survival rate of the skin flaps were evaluated daily. Histopathological evaluation by a blind pathologist at 1, 4, 7 and 21 days was done. Interleukin 1 and 6 in blood samples before and after creation of flaps was measured at 12, 24 and 168 hours following euthanasia.

Results: Flap survival rate at day 21 and IL-6 at day 0, 12 hour and day 1 in propofol group were significantly higher than ketamine group and IL-1 was not significantly different. The amount of collagen deposition at days 1 and 7, epithelialization at days 1 and 4, fibroblast proliferation at day 21 and vascularity at days 4, 7 and 21 in propofol group were significantly more than ketamine, but the inflammatory cells infiltration at day 7 in propofol group was less than ketamine. Pathological signs of healing were more prominent in propofol group.

Conclusion: It is concluded that propofol has more restorative effect on skin flap survival in comparison with ketamine, but its definite confirmation needs more precisely researches.
