A Prospective Trial to Reduce Post-Operative Pain in Implant Based Breast Reconstruction
Post-operative Pain
About this trial
This is an interventional treatment trial for Post-operative Pain focused on measuring pain, breast cancer, breast implant, breast reconstruction
Eligibility Criteria
Inclusion Criteria:
- Women undergoing immediate unilateral or bilateral tissue expander breast reconstruction following therapeutic skin-sparing or nipple-sparing mastectomy requiring postoperative expansions
- Women undergoing immediate bilateral tissue expanders breast reconstruction following risk-reduction (prophylactic) skin-sparing or nipple-sparing mastectomy requiring postoperative tissue expansions.
Exclusion Criteria:
- Subjects who are unable to read or speak English;
- Breast reconstruction using the latissimus dorsi flap combined with a tissue expander;
- Documented diagnosis of chronic pain, chronic migraine, upper limb spasticity, cervical dystonia, axillary hyperhidrosis, strabismus or blepharospasm;
- Hypersensitivity to any botulinum toxin (BT) preparation or to any of the components in the formulation;
- Infection at the proposed site of injection;
- Pre-existing neuromuscular disorders (including diagnosed myasthenia gravis, Eaton-Lambert syndrome, or amyotrophic lateral sclerosis);
- Aminoglycosides intake at the time of surgery (these antibiotics can potentiate the effect of BT);
- Women who are pregnant or breast feeding.

Current standard post-operative care for expander-implant breast reconstruction surgery consists of conventional pain medications including narcotics (like morphine, etc.) and sedatives (like valium). Placebo application during surgery will be made to establish perfection in the study design in terms of randomization and blinding. Injections will be done intramuscularly to the main chest muscle (pectoralis major) by the surgeon.
Current standard post-operative care for expander-implant breast reconstruction surgery consists of conventional pain medications including narcotics (like morphine, etc.) and sedatives (like valium). Patients will receive through an injection into the chest 10 ml (about 2 teaspoons) of 0.5% bupivacaine during surgery. Injections will be done intramuscularly to the main chest muscle (pectoralis major) by the surgeon.
Current standard post-operative care for expander-implant breast reconstruction surgery consists of conventional pain medications including narcotics (like morphine, etc.) and sedatives (like valium). Patients will receive through an injection into your chest 50 U of Botox diluted in 4ml (about 1 teaspoon) of normal saline per breast during your operation. Injections will be done intramuscularly to the main chest muscle (pectoralis major) by the surgeon.
