Ultrasonography-Guided Oblique Subcostal Transversus Abdominis Plane Block in Combination with Ultrasonography-Guided Rectus Sheath Block for Anaesthesia in Abdominal Wall Surgery.

Abdominal wall blocks provide considerable analgesia for relieving post-operative pain. Although they have been performed generally for post-operative pain management, abdominal wall blocks can be used as the principal anaesthesia method in certain cases. In this study, the case of a 47-year-old male patient who underwent surgical excisional biopsy for 2 vague intramuscular mass lesions (was within the rectus abdominis muscle and the other was within the transversus abdominis muscle) was presented. Ultrasonography (USG)-guided oblique subcostal transversus abdominis plane block in combination with USG-guided rectus sheath block was performed successfully as anaesthesia for the abdominal wall surgery. The intervention was performed fully under regional anaesthesia without any need for deep sedation or general anaesthesia.
