Abstract Ultrasound guided transversus abdominis plane (TAP) blockade has been rapidly evolving leading to the development of the most recent approach called oblique subcostal approaches. Preliminary data have shown that this approach provides wider sensory blockade and is suitable for surgery both superior and inferior to the umbilicus. On the other hand, evidence and experience in the use of paravertebral blockade has mounted. The safety concerns from previous decades have proved to be unfounded with TPV block having a comparable rate of complications to thoracic epidurals and intercostal blockade. The use of ultrasound offers the capability to place a catheter in the paravertebral space with real-time image guidance. This study aimed at comparing the analgesic and opioid-sparing effects of oblique subcostal transversus abdominis plane (OSTAP) block with unilateral thoracic paravertebral (TPV) block in patients undergoing open cholecystectomy under general anesthesia. After obtaining approval by the Hospital Ethics Committee, and written informed patient consent, this work was conducted on 46 American Society of Anesthesiologists (ASA) physical statuses I and II patients of both sexes undergoing open cholecystectomy under general anesthesia at Suez Canal University Hospital. |
