Effect of Pectoral Nerve Block on Post-op Pain in Patients Undergoing Mastectomy and Immediate Reconstruction

22. september 2016 opdateret af: Jeannie Shen, Huntington Memorial Hospital

Pectoral Nerve Block vs. Standard Anesthesia in Patients Undergoing Mastectomy and Immediate Breast Reconstruction: Impact on Post-operative Pain and Nausea/Vomiting

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.

Detaljeret beskrivelse

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.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: GA + Pec Block
Following induction of general anesthesia, the patients in the intervention group will undergo an ultrasound-guided pectoral block. With the patient in proper position, the infraclavicular and axillary regions are prepped with chlorhexidine. An US probe is placed below the third of the clavicle over the pectoralis major muscle. After identifying the appropriate anatomical structures, a 21-gauge echogenic needle is advanced under US visualization to the tissue plane between the pectoral major and pectoral minor muscles where the lateral and medial pectoralis nerves lie and 15 mL of 0.25% bupivacaine will be deposited. 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.
Enhed: Ultrasound
Pectoral nerve block is a regional block administered under ultrasound guidance which blocks the nerves of the thorax and chest areas.
Medicin: 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.
