Temperature monitoring practices during regional anesthesia
Monitoring and maintaining body temperature during the perioperative period has a significant impact on the risk of myocardial ischemia, cardiac morbidity, wound infection, surgical bleeding, and patient discomfort. To test the hypothesis that body temperature is inadequately monitored during regional anesthesia (RA), we randomly surveyed 60 practicing anesthesiologists to determine practice patterns for temperature monitoring. Only 33% of the clinicians surveyed routinely monitor body temperature during RA. Although skin temperature monitoring has limitations, it was the most commonly used method among the survey respondents. When temperature is monitored during RA, most clinicians use either liquid crystal skin-surface monitoring or axillary temperature probes. Of those surveyed, < 15% use acceptable core temperature monitoring techniques (urinary bladder or tympanic membrane). In conclusion, it seems that body temperature is often not monitored in patients receiving RA. Implications: The results of this survey of practicing anesthesiologists indicate that body temperature is often not monitored in patients receiving regional anesthesia. It is therefore likely that significant hypothermia goes undetected and untreated in these patients.
