Effects of the menstrual cycle on bispectral index and anesthetic requirement in patients with preoperative intravenous dexmedetomidine following propofol induction.

ABSTRACT: Several studies have suggested that the menstrual cycle has the impact on sedation. No previous study has evaluated the effects of the menstrual cycle on sedation level and propofol requirement with preoperative intravenous dexmedetomidine.
