Summary

Regional Anesthesia is a procedure in which numbing medication is injected around nerves that transmit pain from areas involved in a surgery. The objective is to block the nerves so a patient does not feel pain after surgery. Regional nerve blocks offer many advantages over traditional anesthetic techniques, including faster recovery time, fewer side effects and a dramatic reduction in post-surgical pain.

The use of regional anesthesia in breast reconstructive surgery, such as the latissimus dorsi flap, has led to major improvements in patient care. Today, the most common regional anesthetic used in latissimus dorsi flap reconstruction is the intercostal nerve block, where numbing medication is injected around the nerves supplying the chest wall.

While intercostal nerve blocks have been used successfully in breast surgery, they do not provide a complete nerve block to the chest wall, as there are some nerves that are unaccounted for in the block which can contribute to a patients pain after surgery.

The mixed pectoral one / serratus plane block (PECI/SPB) block is another regional nerve block that has been successfully used by anesthesiologists at The Ottawa Hospital and offers a more complete pain blockade than the intercostal nerve block, as it includes more nerves that supply the breast. In addition to this, the intercostal nerve block is a so-called "blind-technique" compared to the PECI/SPB block, which is more accurately guided by ultrasound. Blind techniques are associated with higher failure rates.

Both the intercostal nerve block and the PECI/SPB nerve block have been used successfully at the Ottawa Hospital. In this study, the investigators propose a prospective, double blinded, randomized controlled, head to head comparison of the PECI/SPB and intercostal nerve block to determine which block is associated with the best pain blockade and patient satisfaction in lattissimus dorsi flap surgery.
