Paravertebral Versus Pectoralis Block for Post Mastectomy Pain

Start date: October 1, 2018
Phase: N/A
Study type: Interventional

Post-mastectomy pain affects more than half of patients undergoing the procedure and can last for years. It has been well established that development of chronic pain is related to experienced pain in the perioperative period. This study therefore aims to assess if both acute and chronic post-operative mastectomy pain can be better managed by a novel regional anesthesia nerve block known as the pectoralis block (PECs). The PECs block is easier for patients to position for placement, has less risk of harm to nearby structures, and less risk for systemic uptake of local anesthetic in comparison to the paravertebral block. The PECs block has a strong safety profile. Standard of care at University of Wisconsin (UW) hospital is to utilize regional anesthesia for post op pain management. While PVB is performed on a regular basis at UW per surgeon request, Surgeon can request for PECS block in patients where a PVB was contraindicated (ie. coagulation issues). PECS is in fact the standard of care at other hospitals. This study will assess outcomes in the post anesthetic care unit (PACU), post-operative day 1, 7 and 30.

Radiofrequency Thoracic Sympathectomy for Chronic Postmastectomy Pain; Randomized Placebo Controlled Study

Start date: April 2018
Phase: N/A
Study type: Interventional

Postmastectomy pain syndrome (PMPS) is a neuropathic pain that can follow surgical treatment for breast cancer, The antineuropathic medications (antidepressants and anticonvulsants) are disappointing and have low success rate. Continues Radiofrequency lesioning has been reported as treatment for several chronic pain conditions.The concept that the clinical effect of RF was caused by formation of heat had not been challenged. Thermocoagulation of nerve fibers would interfere with the conduction of nociceptive stimuli and pain would be relived. Thoracic sympathectomy has been done for many painful conditions that includes complex regional pain syndrome .It offers the benefit over stellate ganglion block as it blocks the Kuntz fibers that connect to the brachial plexus roots without passing through stellate ganglion.

Prevention of Post Mastectomy With Intraoperative Ketamine

Start date: May 1, 2017
Phase: Early Phase 1
Study type: Interventional

Aim 1: To determine the effectiveness of perioperatively administered ketamine to decrease acute and persistent postmastectomy pain (PPMP). Hypothesis 1.1: Patients undergoing partial or total mastectomy treated with a bolus and perioperative infusion of the NMDA-receptor antagonist ketamine will have decreased postoperative pain and opioid utilization compared to those receiving saline control. Hypothesis 1.2: Patients undergoing partial or total mastectomy treated with a bolus and perioperative infusion of the NMDA-receptor antagonist ketamine will have decreased persistent postoperative pain measured at one year after surgery. Aim 2: To determine whether there is increased power to detect therapeutic effectiveness in an interventional preventive trial, by enrichment with patients at high risk of PPMP. Hypothesis 2.1: Ketamine will have a greater analgesic and opioid sparing effect on pain scores in high-risk patients than non-high risk patients, compared to placebo. Hypothesis 2.2: Ketamine will have a greater preventive effect on pain burden scores at one year after surgery in high-risk patients than non-high risk patients, compared to placebo.
