Interventions

In the supine position, after the skin sterilization, ultrasound with a high-frequency linear probe will be placed subcostally and from the xiphoid to the right iliac crest obliquely. The rectus abdominis and underlying transversus abdominis muscles will be identified. The local anesthetic solution (%0.5 Bupivacaine 10ml + %1 Prilocaine 10ml + %0.9 NaCl 10ml) will be injected after negative aspiration to the transversus abdominis plane between the rectus abdominis and transversus abdominis muscles along the oblique subcostal line.

dual tap blockoblique subcostal tap block

In the supine position, after the skin sterilization, ultrasound with a high-frequency linear probe will be placed subcostally and from the xiphoid to the right iliac crest obliquely. %0.9 NaCl 30ml will be injected after negative aspiration to the transversus abdominis plane between the rectus abdominis and transversus abdominis muscles along the oblique subcostal line.

posterior tap block

After the oblique subcostal TAP block, the operation table will be slightly turned left laterally for better visualization of the blocking area. The same high-frequency linear ultrasound (Esaote MyLab5) probe will be placed over the postero-lateral abdominal wall, posterior of the mid-axillary line between the costal margin and iliac crest. After the identification of the internal abdominis, transversus abdominis, and quadratus lumborum muscles, the needle will be advanced into the transversus abdominis plane between the internal abdominis and transversus abdominis muscles, at the aponeurosis of quadratus lumborum and these muscles. The local anesthetic solution (%0.5 Bupivacaine 10ml + %1 Prilocaine 10ml + %0.9 NaCl 10ml) will be injected after negative aspiration.
