Therapeutic Hypothermia in ICUs.

Recent research on Therapeutic Hypothermia (TH) post cardiac arrest has raised questions about its implementation and benefits. TH to 32-34 degrees C is still included in international guidelines for post-cardiac arrest care. We investigated how Irish ICUs are utilising TH as part of their management of patients post cardiac arrest using a telephone survey of all Irish ICUs. All 25 ICUs in Ireland participated. As of quarter 2 2014, TH was part of post-cardiac arrest management in 20 ICUs (80%), which is similar to international figures. 2011 was the median year for units to start using TH in Ireland. Over half 13 (52%) of Irish ICUs have experience with cooling more than 10 patients. Despite lack of evidence for its benefit, 12 ICUs (48%) use TH for OHCA non VF-VT arrests. Lack of resources was cited by 2 ICUs (8%) as well as no local consensus by 1 ICU (4%) prevented a small minority adopting the protocol. Similar methods of inducing and maintaining TH were found in Ireland as with overseas. Interest was expressed in recent research on TH and in 2 ICUs local practice had changed because of it. An updated international resuscitation guideline is awaited.
