About

This study aims to compare the ultrasound-guided edge of laminar block (ELB) and erector spinae plane block (ESPB) for postoperative analgesia in patients undergoing video-assisted thoracic surgery (VATS).

Full description

Postoperative pain after thoracic surgery, which is attributed to muscle incisions, rib retractions, and intercostal nerve damage, may be severe enough to cause pulmonary complications, such as atelectasis, pneumonia, and increased oxygen consumption.

The erector spinae plane block (ESPB) is used for managing post-thoracotomy pain and has numerous advantages that make it an attractive alternative technique. The ESPB injects a local anaesthetic around the erector spinae muscle at approximately the level of the T5. It may be able to block the dorsal and ventral rami of the thoracic spinal nerves.

A novel technique of retrolaminar block (RLB) called the edge of laminar block (ELB) to provide sensory analgesia during rib fracture surgery.
