Yemekten Sonra İçilen Sigaranın Superior Mezenterik Arter ve Portal Ven Hemodinamiğine Etkisi: Doppler Ultrasonografi Çalışması

Amaç: Sağlıklı genç erişkinlerde, yemekten sonra içilen sigaranın mezenterik dolaşımdaki oluşturduğu değişikliklerin araştırılmasıdır. Yöntem: Çalışmaya 28 sigara içmeyen, 22 sigara içen olmak üzere toplam 50 birey katıldı. Üç gruba ayrıldı. Grup A: Sigara içmeyenler (n=28), Grup B: Sigara kullanan ve yemek sonrası da içmelerine izin verilenler (n=18), Grup C: Sigara kullanmakta olan ve yemek sonrası içmelerine izin verilmeyenler (n=16). 12 olgu hem grup B, hem de grup C’ye dahil edildi. Olgulara açlıkta Doppler sonografi yapıldı ve superior mesenterik arter (SMA) ve portal ven (PV) akım parametreleri ölçüldü. Standart bir yemek sonrasında 30, 60 ve 90. dakikalarda ölçümler tekrar edildi. Bulgular: Grup B’de SMA’in pik sistolik hız (PSH) ortalamaları hem açlık hem postprandial dönemde anlamlı olarak yüksekti (p=0,048). Gruplar arasında damar çap ortalamaları ve akım volümleri arasında sigara kullanımına göre fark yoktu (F=1,542, p=0,222; F=2,082, p=0,134). SMA’daki çap değişiklikleri her üç grupta farklı idi (F=6,406, p
