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
