 Normally, higher levels of preoperational stress or anxiety affect behavior and recovery after the operation. Moreover, patients undergoing mastectomy are usually young women, and this demographic is known to experience higher levels of stress and anxiety than any other. Anesthetizing patients involves more than just anesthesia in operation; it also includes all of the preoperative treatments for optimizing a patients condition and promoting quick postoperative recovery. Pharmacological premedication for anxiolysis or amnesia before anesthesia has been a common means of sedation that many studies have investigated. However, such studies have focused on alleviating patients anxiety and on how far patients can obey induction for sedation; there has been no research on post-operational prognoses, the ultimate purpose of reducing anxiety.
