The aim of this study was to investigate changes in PI in patients undergoing surgery in the supine, prone, and sitting positions, and to assess the effect of body mass index (BMI) on the relative change in PI (ΔPI). Material and Methods: This is a prospective cross-sectional observational study. A total of 82 patients were enrolled between June 2023 and December 2023, including individuals over 18 years of age. The study investigated the effects of different patient positions (supine, sitting, and prone) and BMI on the relative change in perfusion index.Results: Of the patients, 52.4% were male (n = 43). It was found that 43.9% of the patients had a BMI greater than 25 kg/m² (n = 36). The operations were performed in the prone position in 32.9% of cases (n = 27), supine position in 32.9% (n = 27), and sitting position in 34.1% (n = 28). No statistically significant difference was observed in the PI value at 0 minutes across all groups. The PI values at 10, 20, and 30 minutes were highest in Group 1 patients. It was found that the PI values were statistically higher in patients with a BMI KW - Patient positions KW - Perfusion index KW - Overweigth KW - Anesthesia N2 - Amaç: Anestezi indüksiyonundan sonra cerrahi pozisyondaki değişiklikle gözlenen perfüzyon indeksi (PI) değerindeki değişiklik birçok faktörden etkilenir. Bu çalışmanın amacı sırtüstü, yüzüstü ve oturma pozisyonlarında ameliyat edilen hastalarda PI'daki değişikliği ve vücut kitle indeksinin (VKİ) PI'daki (ΔPI) bağıl değişiklik üzerindeki etkisini araştırmaktır. Gereç ve Yöntemler: Bu prospektif kesitsel gözlemsel bir çalışmadır. Haziran 2023 ile Aralık 2023 arasında 18 yaş üstü, sırtüstü, oturma ve yüzüstü pozisyonlarda olmak üzere toplam 82 hasta kaydedildi ve hasta pozisyon değişiklikleri ve VKİ değerlerinin ΔPI üzerindeki etkileri araştırıldı.Bulgular: Hastaların %52,4'ünün erkek olduğu (n: 43) görüldü. Hastaların %43,9’unun (n:36) BKİ’sinin 25 kg/m2’nin üzerinde olduğu görülmüştür. Cerrahi operasyonlar %32,9 yüzüstü pozisyonda (n:27), %32,9 sırtüstü pozisyonda (n:27) ve %34,1 oturur pozisyonda (n:28) gerçekleştirilmiştir. Tüm gruplarda PI 0 değerinde istatistiksel olarak anlamlı bir fark olmadığı görülmektedir. PI 10-20-30 değerinin grup 1 hastalarında en yüksek düzeyde olduğu görülmektedir.
