Review Meta AnalysisNeural Blockade for Persistent Pain After Breast Cancer Surgery.
Persistent pain after breast cancer surgery is predominantly a neuropathic pain syndrome affecting 25% to 60% of patients and related to injury of the intercostobrachial nerve, intercostal nerves, and other nerves in the region. Neural blockade can be useful for the identification of nerves involved in neuropathic pain syndromes or to be used as a treatment in its own right. ⋯ In this systematic review, we found only 7 studies (n = 135) assessing blocks directed at 3 neural structures-stellate ganglion, paravertebral plexus, and intercostal nerves-but none focusing on the intercostobrachial nerve. The quality of the studies was low and efficacy inconclusive, suggesting a need for well-designed, high-quality studies for this common clinical problem.

Clinical Accuracy and Safety Using the SynchroMed II Intrathecal Drug Infusion Pump.
We evaluated the infusion accuracy and device-related safety of implantable drug infusion pumps in subjects with chronic pain or severe spasticity. ⋯ The pump accurately delivered intrathecal medication in the clinical setting of this study. Adverse events were similar in nature and severity to those described in the product labeling and literature.
