AbstractTargeted temperature management (TTM) is widely used for postcardiac arrest management of patients with out-of-hospital cardiac arrest. However, the use of TTM for patients with in-hospital cardiac arrest (IHCA) is controversial. The aim of this study was to investigate the role of TTM in the management of patients with IHCA. The medical records of all IHCA patients who were resuscitated and returned to spontaneous circulation from January 2011 to December 2016 were reviewed. After excluding patients with new do not resuscitate orders and those who died within 24 hours, 262 patients were eligible for analysis. Thirty-five of the 262 patients (13.3%) received TTM after IHCA. Patients who received TTM and standard supportive care (SSC) had similar baseline epidemiological status. The TTM patients were older and had a longer cardiac pulmonary resuscitation duration; however, the differences were not statistically significant. The 28-day survival rate was not significantly different between groups (12/35 in the TTM group [34%] vs. 114/225 in the SSC group [50%], p = 0.079). In the patients with good neurological status before arrest (Glasgow-Pittsburgh cerebral performance category [GP-CPC] scores: 1-2), there was no significant difference in the 28-day survival between groups (11/26 in the TTM group [42.3%] vs. 81/154 [52.6%] in the SSC group; p = 0.332). In this subgroup, the TTM patients had poorer neurological outcomes at discharge (GP-CPC score 1-2) than the SSC patients (1/26 in the TTM group [3.8%] vs. 57/154 in the SSC group [37%]; p = 0.001). TTM was not associated with better 28-day survival than usual care among the patients with IHCA in this study, and the TTM patients had less favorable neurological outcomes at discharge. Randomized clinical trials are needed to assess the efficacy of TTM for IHCA patients.
