The Effects of Body Mass Index on Efficacy of Intermittent Pneumatic Compression

Abstract

Objectives: The aim of our study was to compare the efficacy of intermittent pneumatic compression on venous hemodynamics in individuals with different body mass indexes (BMIs). Materials and Methods: The study included a total of 48 healthy volunteers. The participants were classified into three groups according to their BMIs as <24.9 kg/m2 (group I), 25-29.9 kg/m2 (group II), and >30 kg/m2 (group III). The measurements of pulse, arterial blood pressure and oxygen saturation were made, and venous ultrasonography was performed by the investigator. The measurements were repeated at the 30th minute of intermittent pneumatic compression. Vena femoralis communis (common femoral vein) (VFC) vein flow dynamics were evaluated 1-1.5 cm proximal to the junction of the VFC and great saphenous vein. Results: The increases observed in the peak systolic flow rates of both right and left VFC in groups I and II were found to be significantly higher compared to those observed in group III at the 30th minute of intermittent pneumatic compression application. (p<0.001, p=0.012, and p=0.049, respectively) Conclusion: We demonstrated that intermittent pneumatic compression application increased the femoral venous flow; however, this effect changed among individuals with different BMIs. We believe that BMI should be considered as an independent risk factor in patients for whom venous thromboembolism prophylaxis has been planned, which is frequently encountered in emergency units, and that providing the same effect in individuals with different physical properties is important in planning the prophylaxis.

Vücut Kitle İndeksinin Aralıklı Pnömatik Kompresyon Etkililiği Üzerindeki Etkileri

Abstract

Amaç: Çalışmamız aralıklı pnömatik kompresyonun, farklı vücut kitle indeksine (VKİ) sahip bireylerde venöz hemodinamiye olan etkilerinin karşılaştırılmasını amaçlamaktadır. Gereç ve Yöntem: Çalışmaya sağlıklı gönüllülerden olmak üzere toplam 48 birey dahil edildi. Çalışmaya alınan gönüllüler, hesaplanan VKİ’leri <24,9 kg/m2 olan (grup I), 25-29,9 kg/m2 arasında olan (grup II) ve >30 kg/m2 (grup III) olan olmak üzere üç gruba ayrıldı. Nabız, arteriyel kan basıncı ile oksijen satürasyonu ölçümleri ve venöz ultasonografi incelemeleri çalışmayı yürüten araştırmacı tarafından yapıldı. Aralıklı pnömatik kompresyon uygulamasının 30. dakikasında ölçümler tekrarlandı. Vena femoralis communis (ortak femoral ven) (VFC) çapı ve venöz akım dinamiği, VFC’nin büyük safen venle bileşkesinin 1-1,5 cm proksimalinden değerlendirildi. Bulgular: Grup I ve grup II’de olan bireylerin, aralıklı pnömotik kompresyon uygulamasının 30. dakikasında, sağ ve sol VFC tepe sistolik akım hızlarının artışı, grup III’de olan bireylerin, sağ ve sol vena femoralis communis tepe sistolik akım hızlarının artışına oranla istatistiksel olarak anlamlı yüksek bulundu (sırasıyla, p<0,001, p=0,012, p=0,049). Sonuç: Aralıklı pnömatik kompresyon uygulamasının femoral venöz akışı arttırdığını; ancak bu etkinin farklı VKİ’lere sahip bireyler arasında değiştiğini gösterdik. VKİ’nin, acil servislerde sıklıkla karşılaşılan, venöz tromboembolizm profilaksisi planlanlanan hastalar için bağımsız bir risk faktörü olarak düşünülmesi gerektiğine ve farklı fiziksel özeliklere bireylerde aynı etkiyi sağlamasının önemli olduğu kanaatindeyiz.
