Spontan Solunumu Olan Gönüllülerde Cerrahi Hasta Pozisyonlarının Plet Değişkenlik İndeksi , Perfüzyon İndeksi ve Noninvaziv Sürekli Kardiyak Output Ölçüm Yöntemi Üzerine Olan Etkisi

Amaç: Cerrahi prosedür için verilen farklı pozisyonlar doku perfüzyonunda ve kardiyak outputta değişikliklere neden olabilir. Bu çalışmada spontan solunuma sahip katılımcılarda plet değişkenlik indeksinin (PVI), perfüzyon indeks (PI) ve noninvaziv sürekli kardiyak output ölçüm yöntemi (EscCO) nin farklı cerrahi pozisyonlardaki değişimlerini araştırmayı amaçladık.Materyal ve Metod: 20 katılımcıdan oluşan bir sağlıklı birey grubu prospektif gözlemsel çalışmaya dahil edildi. Sırasıyla Supin, 30 derece baş yukarı, 45 derece baş yukarı, 20 derece Trendelenburg, 20 derece ters-Trendelenburg, ve pron pozisyonları uygulandı. Her pozisyon arası 10 ar dk olacak şekilde süre tutuldu. Her pozisyon değişikliğinden önce gönüllüler sırtüstü pozisyona alındı ve beş dakika dinlendikten sonra yeni pozisyon verildi. Pozisyon değişiminden sonraki 5. dakika PI, PVI, EscCO, SpO2 değerleri kayıt altına alındı.Bulgular: Katılımcıların farklı pozisyondayken ölçülen PI, PVI ile EscCO değerlerinde istatistiksel olarak anlamlı bir fark bulunamadı.Sonuç: Bu çalışma, PI, PVI ile EscCO nun tüm cerrahi pozisyonlarda herhangi bir değişikliğe uğramadığını ve her üç parametrenin de spontan solunumuna sahip genç sağlıklı bireylerde pozisyondan etkilenmediği ortaya koymuştur.

The Effect of Surgical Patient Positions on Plet Variability Index, Perfusion Index and Noninvasive Continuous Cardiac Output Measurement Method in Voluntary Breathing Volunteers

Background: Different positions given for the surgical procedure can cause changes in tissue perfusion and cardiac output. In this study, we aimed to investigate the changes of pleth variability index (PVI), perfusion index (PI) and noninvasive continuous cardiac output measurement method (EscCO) in different surgical positions in participants with spontaneous breathing. Materials and Methods: A sample of 20 healthy individuals was included in the prospective observational this study. Participants held six different positions: supine, prone, 30 degrees upside, 45 degrees upside, trendelenburg (20-degrees head down), and reverse trendelenburg (20-degrees head up). The time was kept 10 minutes between each position. Before each position change, volunteers were placed in the supine position and after five minutes of rest, a new position was given. After the position change, PI, PVI, EscCO, peripheral capillary oxygen saturation values at 5th minutes were recorded. Results: No statistically significant difference was found in PI, PVI and EscCO values measured while the participants were in different positions (p >0.05). Conclusion: This study revealed that PI, PVI and EscCO did not change in all surgical positions, and this parameters were not affected by position in young healthy individuals with spontaneous breathing.
