An Epidemiology Survey on the Incidence of Perioperative Hypothermia
An Epidemiology Survey on the Incidence of Perioperative Hypothermia of Patients Undergo Elective Operation With General Anaesthesia in Beijing Area
- The purpose of this study is to understand and grasp the incidence rate of hypothermia during perioperative period of elective operations under general anaesthesia in Beijing.
- The purpose of this study is to carry out a subgroup analysis on the survey data and explore the high-risk factors for the incidence of hypothermia.

Gedetailleerde beschrijving
This survey was anticipated to enroll 800 patients who underwent elective operations with general anaesthesia from 24 hospitals in Peking. After obtaining approval from the Ethical Committee related to research involving human subjects,the investigators will enroll the patients according to the inclusion and exclusion criterion. The tympanic temperature(measured by Braun PRO4000 Thermometer) will be monitored at the following time points respectively: arrived at waiting area, enter the OR room, 5 min before and after anesthesia induction, every 15 min during the operation, operation ended,arrived at PACU. Other information will also be collected, the investigators will record the type and dosage of anesthesia drug,duration of surgery and anesthesia, the patient warming method or if it is used.operation room temperature,the amount of the infusion of intravenous fluids and blood,etc. during the whole operation procedure. The other information will be followed up and recorded after the operation(within 30 days postoperation) which incudes ICU stays, hospital stays, incision infection, new cardiology events.etc.
The contract research organization will be delegated to do the site monitor once a week for each hospital participate the survey during the recruitment and perform the source data validation at the same time to review the related medical records,source data and the case report forms, etc.to ensure the data accuracy and completeness
Data management will be conduct through the whole survey procedure. EPIDATA3.1 software was used for compile the inputting procedure for data inputting and management. In order to guarantee the correctness of the data, two data managing staffs should input and verify the data independently.
SAS9.2 statistical analysis software was used for the calculation of all the statistical analyses. The number of cases, mean, standard deviation, median value, maximal value and minimal value should be calculated for the descriptions of the qualitative parameters. Number of cases and percentages are used for the descriptions on the classification parameters.Two side test is used for all the statistical tests, P<0.05 indicates that the difference is statistically significant (unless indicated otherwise), and 95% confidence is used as the confidence interval.
