简要总结
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.

结局指标
主要结局
Anesthetic Recovery Times
时间窗: 0-72 hours after surgery
recovery from anesthesia will be measured by short-term outcomes like time to tracheal extubation and response to verbal commands, as well as by psycho-vigilance testing up to 72 hours postoperatively
次要结局
- sensitivity to sevoflurane during inhalation induction to anesthesia, determined by bispectral index of the EEG(during anesthetic induction)
- pain and sleepiness(from 0-72 hours after surgery)
