Abstract
OBJECTIVE
To evaluate characteristics of septic shock patients treated with hydrocortisone (HC) due to suspicion of critical illness-related corticosteroid insufficiency (CIRCI) as compared to septic shock patients without suspicion of CIRCI.
DESIGN
Retrospective study between February 2010 and October 2017.
SETTING
University teaching hospital ICU.
ANIMALS
Data were collected for 47 dogs with septic shock. Twenty-one dogs were treated with HC (HC-treated) due to suspicion of CIRCI. Twenty-six dogs did not receive HC (non-HC-treated).
INTERVENTIONS
HC was administered either as an intermittent IV bolus or as a constant rate infusion (CRI) to those patients with suspected CIRCI.
MEASUREMENTS AND MAIN RESULTS
Significantly higher baseline APPLEfull scores and predicted mortality were detected in the HC-treated patients compared to non-HC-treated patients (0.87 vs 0.44 for predicted mortality, P = 0.039). Patients in the HC-treated group were on more vasopressors and cardiotonics than those in the non-HC-treated group (2.5 vs 1.5, P <0 .001). All patients initially responded to vasopressor administration, with average time to resolution of hypotension being 90 minutes for the HC-treated group compared to 60 minutes for the non-HC-treated group (P = 0.640). However, HC-treated patients took significantly longer to have a sustained resolution (a systolic blood pressure > 90 mm Hg or a mean blood pressure > 65 mm Hg for at least 4 h) of their hypotension after starting vasopressors, as compared to their non-HC-treated counterparts (8.5 vs 4 h, P = 0.001). Three (14.3%) HC-treated patients survived to discharge compared to 9 (34.6%) non-HC-treated patients, but this was not statistically significant.
CONCLUSIONS
HC-treated patients had a higher baseline risk of mortality than non-HC-treated patients. There was no significant difference in survival between the HC-treated and non-HC-treated septic shock patients. Further studies are needed to evaluate the use of HC in patients with suspected CIRCI.
