  Purpose

American Society of Anesthesiologists (ASA) physical status scale has been used worldwide for assessing the status of patients before operation. However, merely the value of ASA scale did not give enough information of patients to determine their prognosis and improvement of outcomes. Since 1948, World Health Organization (WHO) defined health as the state of complete physical, mental and social well-being and not merely the absence of disease or infirmity. Therefore, the investigators hypothesized that the ASA scale only was needed to be modified and should be replaced by a comprehensive gauge to evaluate the status of patients in depth. Based on this thought, the investigators used a new system, i.e., physical-psycho-social (PPS) scale, to assess the overall state before surgical procedures.

Primary Outcome Measures:
  • Time of recovery [ Time Frame: Six months after operation. ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Intraoperative consumption of drugs [ Time Frame: 1 day after operation ] [ Designated as safety issue: Yes ]
  • Incidence of side events [ Time Frame: 72 hours after operation ] [ Designated as safety issue: Yes ]
  • Hospitalization days [ Time Frame: From 0 min after operation to the time duration of discharge home, this measure would be varied in different patients ] [ Designated as safety issue: No ]
  • Psychological state [ Time Frame: Six months after operation ] [ Designated as safety issue: Yes ]
