Outcomes
Primary outcome [1] 286043 0
Penehyclidine Hydrochloride reduces the incidence of intraoperative awareness in patients undergoing breast cancer surgery during general anesthesia.
Timepoint [1] 286043 0
Every Patient was interviewed twice, at anytime between 2 and 6 hours postoperatively and at any time between 24 and 48 hours postoperatively.

Patients with higher degree anxiety levels were liable to report intraoperative awareness.
Timepoint [1] 295031 0
Before they received Penehyclidine Hydrochloride or saline, the patients were assessed preoperative anxiety levels by using a 100-mm visual analogue scale.

Summary
Brief summary
Extensive evidence has proved that basal forebrain cholinergic system play extremely important role in explicit memory.Penehyclidine hydrochloride (PHC; (2-hydroxyl-2-cyclopentyl-2-phenyl-ethoxy) quinuclidine) is a new anticholinergic drug with both antimuscarinic and antinicotinic activity while retaining potent central and peripheral anticholinergic activity.The primary purpose of this study is to verify the effectiveness of PHC reducing the incidence of intraoperative awareness. Modified Brice interview was used to assess awareness in the study.
