Abstract

Increased intraabdominal pressure decreases the venous return due to compression of vena cava inferior. Lower part of body is supposed to be affected mostly from this hemodynamic changes, especially microcirculation and afterward oxygen saturation in lower extremities. We investigated the relationship between intraabdominal pressure and oxygen saturation of lower extremity measured by pulse oxymetry and whether oxygen saturation of leg is an indicator for intraabdominal pressure. We employed on 5 dogs weighing mean 14.2 kg. Under general anaesthesia, pneumoperitoneum was established via Veres cannula and normal air insufflation at 6 different pressure levels ranging 0-50 mmHg and 3 different time intervals. Measured lower extremity oxygen saturations were analysed by bivariate correlation. Intraabdominal pressure showed a significant negative correlation with lower extremity oxygen saturation(p=0.001, r=0.97). As a conclusion, lower extremity oxygen saturation seems tobea reliable indicator for increased intraabdominal pressure. Further clinical and experimental studies are necessary in this subject.

Özet

Karin içi basinç artisi ile V. Cava inferior(VCI)'un baskilanmasi sonucu venöz dönüs azalir. Bu hemodinamik degisimden vücudun alt yarisinin, özellikle alt ekstremite mikrosirkülasyonunun fazla etkilenmesi ve bu bölgede oksijen saturasyonunun etkilenmesi beklenir. Pulse oksimetre ile ölçülen alt ekstremite transkutan oksijen saturasyonu(Tc-SaO2) ile karin içi basinç artisi arasinda bir iliski olup olmadigini, bu iliskinin artmis karin içi basincinin bir göstergesi olup olmadigini arastirdik. Bu deneysel çalismada ortalama agirliklari 14.2 kg olan 5 adet köpek endotrakeal entubasyonlu genel anestezi altinda Veres ignesi ile intraabdominal mesafeye girilerek her denekte 0-50 mmHg arasinda degisen 6 farkli basinç düzeyinde 3 degisik sürede beklendi ve bu sirada alt ekstremite transkutan oksijen saturasyon degerleri kaydedildi. Bulunan degerler "bivariate correlation" baginti analiz yöntemiyle degerlendirildi. Karin içi basinç arttikça ve yüksek basinçta kalma süresi arttikça alt ekstremite Tc-SAO2 degerinde azalma anlamli düzeylerde idi (p=0.001, r=0.97). Sonuç olarak alt ekstremite Tc-SaO2 degerleri karin içi basinç artisinin bir göstergesi olarak monitörizasyonda kullanilabilecegi anlasilmaktadir. Pratik kullanima girmesi için ilave klinik ve deneysel çalismalara gerek vardir.
