  Purpose

Despite recent advances in postoperative delirium research, the proportion of patients with postoperative delirium is still high ranging between 20-80%. Although postoperative delirium is a frequent complication and is associated with the need for more inpatient hospital care and longer length of hospital stay, little is known about risk factors for recovery room delirium (RRD) occurred in postanaesthesia care unit. The aim of the study was to determine pre- and intraoperative risk factors for the development of RRD among patients undergoing non cardiovascular surgery.

Further study details as provided by Huazhong University of Science and Technology:

Primary Outcome Measures:
  • The presence of delirium in post anesthesia care unit (PACU) determined by confusion assessment method (CAM) criteria [ Time Frame: at 1 hour after operation ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • heart rate in PACU [ Time Frame: every 10 mins ] [ Designated as safety issue: Yes ]
    heart rate was recorded every 10 min during PACU stay, maximal and minimal heart rate were collected for analysis

  • Pulse Oximeter Oxygen Saturation (SpO2) in PACU [ Time Frame: every 10 mins ] [ Designated as safety issue: Yes ]
  • Hospital-length of stay [ Time Frame: up to 6 months ] [ Designated as safety issue: Yes ]
  • Total health care fees [ Time Frame: up to 6 months ] [ Designated as safety issue: Yes ]

Groups/Cohorts
Delirium
Delirium was determined by CAM
no Delirium
no Delirium was determined by CAM

Detailed Description:

Recovery room delirium (RRD) defined as delirium occurred in PACU was diagnosed according to CAM criteria. Pre-, intra-, and postoperative data of patients undergoing elective non cardiovascular surgery were prospectively collected, univariate and multivariate logistic regression were performed to find the risk factors related to postoperative delirium.
