Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
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.
Ultrasound
Pectoral nerve block is a regional block administered under ultrasound guidance which blocks the nerves of the thorax and chest areas.
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.
GA only
Patients will receive standard general anesthesia.
