Comparison of the Distance of the Erector Spinae Muscle from the Skin at Different Thoracal Levels and Different Positions Under Ultrasonography

Öz

Background: The erector spinae plane block can be executed at various thoracic levels and in different positions. Our study aimed to determine the optimal distance of the erector spinae muscle from the skin and to identify the best ultrasonography imaging quality across different thoracic levels and positions. Materials and Methods: The erector spinae muscle was located using a high-frequency 10-15 MHz linear ultrasound probe at distinct thoracic levels (T1-T2, T5-T6, T11-T12) and in various positions (lateral, sitting, and prone). Results: The proximity of the erector spinae muscle to the skin was found to be significantly closer at the T5-T6 level compared to the T1-T2 and T11-T12 levels (p = 0.001; p < 0.01). In the prone position, the distance of the erector spinae muscle to the skin was significantly lower than in the lateral and sitting positions (p = 0.001; p < 0.01). Conclusions: In an ESPB to be applied at the T5-T6 thoracal level and in the prone position, the erector spinae muscle is closer to the skin, and the ultrasound image is better.

Ultrasonografi Eşliğinde Erektör Spina Kasının Farklı Torakal Seviyelerde ve Farklı Pozisyonlarda Cilde Olan Uzaklığının Karşılaştırılması

Öz

Amaç: Erektör spina düzlem bloğu çeşitli torasik seviyelerde ve farklı pozisyonlarda gerçekleştirilebilir. Çalışmamız, erektör spina kasının deriden optimal mesafesini belirlemeyi ve farklı torakal seviye ve pozisyonlarda en iyi ultrasonografi görüntüleme kalitesini belirlemeyi amaçladı. Materyal ve Metod: Erektör spina kası, yüksek frekanslı 10-15 MHz doğrusal ultrason probu kullanılarak farklı torakal seviyelerde (T1-T2, T5-T6, T11-T12) ve çeşitli pozisyonlarda (yan, oturma ve yüzüstü) konumlandırıldı. Bulgular: Erektör spina kasının cilde yakınlığının T1-T2 ve T11-T12 seviyelerine göre T5-T6 seviyesinde anlamlı olarak daha yakın olduğu görüldü (p=0.001; p<0.01). Yüzüstü pozisyonda erektör spina kasının cilde mesafesi yan ve oturma pozisyonlarına göre anlamlı derecede düşüktü (p=0.001; p<0.01). Sonuç: T5-T6 torakal seviyede ve yüzüstü pozisyonda uygulanacak erektöt spina plan bloğunda erektör spina kası cilde daha yakın olup ultrason görüntüsü daha iyidir.
