Accuracy of the Drager Dual-sensor Temperature Measurement System

This study has been completed.
Sponsor:
Information provided by (Responsible Party):
Andrea Kurz, The Cleveland Clinic
ClinicalTrials.gov Identifier:
NCT00980642
First received: September 18, 2009
Last updated: May 15, 2017
Last verified: May 2017
  Purpose
Our primary hypothesis is that the Draeger dual-sensor temperature monitoring system, used at the forehead, is sufficiently accurate compared to tympanic, bladder or esophageal temperature and oral temperature for routine clinical use during hypothermic conditions, as well as during fever.

Condition Intervention
Hypothermia; Anesthesia Device: Draeger double-sensor Device: Esophageal stethoscope temperature sensor Device: Foley catheter temperature sensor

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: No masking
Primary Purpose: Other
Official Title: Accuracy of the Draeger Dual-sensor Temperature Measurement System in The Perioperative Period

Further study details as provided by Andrea Kurz, The Cleveland Clinic:

Primary Outcome Measures:
  • The Bias Between Temperature Measured by Drager Double-sensor vs Core Temperature [ Time Frame: From anesthesia induction to the end of surgery ]
    Determine if the Drager double-sensor temperature monitoring system, used at the forehead is accurate compared to esophageal temperature for general anesthesia group and bladder temperature for regional anesthesia group.


Secondary Outcome Measures:
  • Sensitivity for Detection of Hypothermia [ Time Frame: From anesthesia induction to the end of surgery ]
    Hypothermia is defined as a temperature < 36 Celsius degree

  • Specificity for Detection of Hypothermia [ Time Frame: From anesthesia induction to the end of surgery ]
    Hypothermia will be defined as a temperature < 36 Celsius degree


Enrollment: 56
Study Start Date: March 2010
Study Completion Date: August 2012
Primary Completion Date: February 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
General anesthesia
Temperature is measured by Draeger double-sensor and esophageal stethoscope temperature sensor every 5-min during the surgery.
Device: Draeger double-sensor
The sensor will be attached to the patient's forehead with adhesive tape, and a small amount of contact gel will be applied between sensor and skin.
Device: Esophageal stethoscope temperature sensor
Esophageal temperature is measured by sensors incorporated into an esophageal stethoscope during the surgery.
Regional anesthesia
Temperature is measured by Draeger double-sensor and Foley catheter temperature sensor every 5-min during the surgery.
Device: Draeger double-sensor
The sensor will be attached to the patient's forehead with adhesive tape, and a small amount of contact gel will be applied between sensor and skin.
Device: Foley catheter temperature sensor
Urinary bladder temperature is measured via a sensor incorporated into a Foley catheter during the surgery

Detailed Description:
We will include patients undergoing general anesthesia or regional anesthesia. The temperature recorded by Draeger dual-sensor monitoring system will be obtained at 5-minute interval.
