Official title
Preoperative Cerebrospinal Fluid (CSF) Levels of Hypocretin and Recovery After Hip Surgery With Combined Spinal and General Anesthesia
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
A specific group of neurons in the brain produces hypocretin, a peptide which has been established as an important regulator of sleep and wakefulness. Activation of these neurons (increased hypocretin) stabilizes wakefulness; impairing or blocking these neurons (decreased hypocretin) promotes sleep. Evidence suggests that these neurons may be involved in the hypnotic properties of several anesthetics, and play a role in the induction and emergence from anesthesia. In humans there is a considerable inter-individual variability in hypocretin levels. This study aims to investigate how hypocretin levels affect the anesthetic care and recovery of patients undergoing elective hip surgery.
