    Double blind, randomized clinical trial in Mazandaran heart center
    This study is a randomized double-blind clinical trial conducted in Mazandaran Heart Center. Eight-member blocks were defined based on block-randomization. Patients respectively enrolled into the blocks and entered blindly into labetalol or nitroglycerin groups based on defined codes. An angiographic specialist prescribes the medication to the patients based on block-randomization and the investigator recorded the data without knowing the type of prescribed medication. Statistical analysts also was unaware of the interventionist groups. First, the initial diameter of the radial artery was measured before medication administration. Then patients received intra-arterial nitroglycerin (150 micrograms) or intra-arterial labetalol (500 micrograms). Radial artery diameter was re-measured immediately after the medication administration, as well as at the end of the angiography. Any spasm and pain during the procedure was also recorded.
    کارآزمایی بالینی دو سوکور در مرکز قلب مازندران
    این مطالعه یک کارآزمایی بالینی دوسوکور تصادفی شده است که در مرکز قلب مازندران انجام شده است. بلوکهای ۸ تایی بر اساس بلاک رندومیزیشن تعریف گردید. بیماران به ترتیب وارد بلوک ها شده و بر اساس کدهای تعریف شده به صورت کورسازی شده وارد گروه لابتالول یا نیتروگلیسرین می شوند. یک متخصص آنژیوگرافی بر اساس بلوک سازی تصادفی شده، دارو را به بیماران تجویز کرد و محقق بدون اطلاع از نوع داروی تجویزی، داده ها را ثبت کرد. هم چنین آنالیزگر آماری نیز از گروه های مداخله بی اطلاع بود. ابتدا، قطر اولیه شریان رادیال قبل از تجویز دارو اندازه گیری شد. سپس بیماران نیتروگلیسرین داخل شریانی (۱۵۰میکروگرم) یا لابتالول داخل شریانی (۵۰۰ میکروگرم) را دریافت کردند. قطر شریان رادیال بلافاصله پس از تجویز دارو و نیز در انتهای آنژیوگرافی، مجددا اندازه گیری شد. هر گونه بروز اسپاسم و درد نیز در حین پروسیجر ثبت گردید.

  • Intervention groups

    #1
    Intervention group: Initially, the diameter of the radial artery will be measured prior to administration of the drug. Then, the patients will receive intra-arterial labetalol (500 microgram) + nitroglycerin (200 microgram) and the radial artery diameter will be re-measured immediately after the administration of the medication and at the end of the angiography. Any spasticity and pain during the procedure will be recorded.
