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.

Randomized Controlled TrialThoracic paravertebral block and its effects on chronic pain and health-related quality of life after modified radical mastectomy.
Patients undergoing breast cancer surgery frequently experience chronic postoperative pain. The primary objective of this randomized study was to determine if thoracic paravertebral block (TPVB) reduced the incidence of chronic pain after a modified radical mastectomy (MRM) when compared with general anesthesia (GA). ⋯ There is no significant difference in the incidence or relative risk of chronic pain at 3 and 6 months after an MRM when TPVB is used in conjunction with GA. Nevertheless, patients who receive a TPVB report less severe chronic pain, exhibit fewer symptoms and signs of chronic pain, and also experience better physical and mental HRQOL.

Comparative StudyAn Ex Vivo Comparison of Cooled-Radiofrequency and Bipolar-Radiofrequency Lesion Size and the Effect of Injected Fluids.
Radiofrequency (RF) neuroablation is a common therapy for alleviating chronic pain. Larger lesion volumes lead to higher chance of ablating small sensory nerves; therefore, bipolar-RF and cooled-RF are improved alternatives to conventional monopolar-RF. This work provides an ex vivo comparison of bipolar-RF to cooled-RF lesioning in the presence of bone structure using some conventional temperature and time programs and in conjunction with injection of a variety of clinically used substances. ⋯ Cooled-RF yields larger lesions than bipolar-RF under the conditions used in this study. The spherical shape of cooled-RF lesions provides larger volume coverage than lesions obtained with bipolar-RF at IED equals 5, 10, or 15 mm under similar electrode tip temperature and lesioning time.
