Study of Nerve Block Pain Management in Patients Undergoing a Double Mastectomy With Immediate Reconstruction

Patient will be placed in the prone, lateral, or sitting position. With an ultrasound probe placed in the parasagittal or transverse position, the paravertebral space will be identified. Injections will be done in an in-plane manner relative to the ultrasound probe. Local anesthesia will be injected to cover T1-T6 dermatomes.

For PECS-1, the patient will be placed in the supine position with an ultrasound probe placed inferolaterally starting at the mid-clavicular level the pectoralis major and minor will be identified. Injection of local anesthesia will be performed between the pectoralis major and minor

For the serratus block, the patient will be placed in the supine or lateral decubitus position and with an ultrasound probe, in the parasagittal plane, the serratus muscles will be identified. Injections will be done in-plane below the serratus anterior.
