Clinical Trial Summary

Patients undergoing total mastectomy with immediate breast reconstruction with a tissue expander or implant under general anesthesia will be randomly assigned to the addition of a pectoral nerve block or no regional block. Post-operative pain, nausea/vomiting scores will be assessed.


Description:

Patients undergoing total mastectomy with immediate breast reconstruction with a tissue expander or implant under general anesthesia will be randomly assigned to the addition of a pectoral nerve block or no regional block after induction of general anesthesia and prior to the start of surgery. Post-operative pain scores and post-operative pain medication usage will be recorded. Post-operative nausea/vomiting scores and post-op anti-emetic medication usage will be recorded. The clinical impact of pectoral nerve block on this expanding population of patients will be determined.

Intervention

Device:
Ultrasound
Pectoral nerve block is a regional block administered under ultrasound guidance which blocks the nerves of the thorax and chest areas.
Drug:
0.25% bupivacaine
Pectoral nerve block is a regional block administered under ultrasound guidance where 15 mL of 0.25% bupivacaine is instilled between the pectoral major and pectoral minor muscles where the lateral and medial pectoralis nerves lie. In a similar manner, 20 mL of 0.25% bupivacaine will be deposited under ultrasound-guidance at the level of the third rib above the serratus anterior muscle.
