Narcolepsy and opioid-free anesthesia: a review and case report. / Narcolepsia y anestesia libre de opioides: revisión y caso clínico.

INTRODUCTION: Narcolepsy is the second most common sleep disorder. It is characterised by excessive daytime sleepiness together with other symptoms such as cataplexy, sleep paralysis, and hallucinations. The pathophysiology and treatment of this disease, together with its associated syndromes, can severely interfere with anaesthesia. METHODOLOGY: Due to the lack of quality evidence on which to base a high grade of recommendation for anaesthesia in these patients, we performed a non-systematic, narrative review of the literature in Pubmed. We used the descriptors narcolepsy, anesthesia, surgery, perioperative, opioid, obstructive, apnea and sleep both individually and with AND and OR connectors. CONCLUSION: The recommendation to avoid opioids and the stability of opioid-free anaesthesia (OFA) make this approach an option to consider in these patients. We describe a case in which it was used safely.
