Nebulized Fentanyl for Dyspnea: A Retrospective Chart Review.
Nebulized fentanyl is well established for analgesia but its use for dyspnea requires further investigation. The aim of our study was to determine the effectiveness of nebulized fentanyl in treating patients with dyspnea and to determine if there were harmful side effects described by patients or their providers. We used a convenience sample of patients from July 1 2014 to July 1 2018 and performed a retrospective chart review. ⋯ Also, 71% of patients with documented responses experienced an improvement in their dyspnea. Our preliminary data suggest that nebulized fentanyl has limited side effects and may have a role in the treatment of dyspnea. Further research is necessary to determine its efficacy.

Case Reports Multicenter StudyA Multi-Centered Case Series Highlighting the Clinical Use and Dosing of Lidocaine and Mexiletine for Refractory Cancer Pain.
Lidocaine infusion for pain control has been used for years. While some centers transition from continuous infusion lidocaine to oral mexiletine, there are no published studies to guide this conversion in pain and palliative care settings. This is a retrospective case series of 10 cancer patients across four institutions, with attention to dosing of both agents, and subsequent decrease in morphine-equivalent daily dosing (MEDD). ⋯ There was no lidocaine-induced toxicity and no lidocaine levels were obtained. Two of the 10 patients stopped mexiletine early, one from confusion four days after initiation of mexiletine, and the other after six weeks due to dizziness and visual changes. For cancer patients with suboptimal pain control on large doses of opioid, lidocaine infusion followed by oral mexiletine was well tolerated and effective.
