Key result
ICU drop-off hypotension occurred in 54% of post-cardiac surgery patients and was not associated with hospital mortality.
Why the study?
Hypotension is a frequent complication in the ICU after adult cardiac surgery, motivating an assessment of its frequency upon arrival from the operating room and its relation to hospital outcomes.
Does hypotension within the first 30 minutes of ICU arrival after adult cardiac surgery increase hospital mortality and length of stay compared to maintaining normotension?
Cohort (n=417)
No
Does hypotension within the first 30 minutes of ICU arrival after adult cardiac surgery increase hospital mortality and length of stay compared to maintaining normotension?
Hypotension within 30 minutes of ICU arrival occurs in over half of post-cardiac surgery patients—particularly those with diabetes, coronary artery disease, or longer bypass times—and is associated with prolonged mechanical ventilation, highlighting the need for structured OR-to-ICU handoff communication regarding vasopressor bolus use.

ICU drop-off hypotension was not linked to higher mortality; leaves open effects on other outcomes and need for prospective studies.
BACKGROUND: Hypotension is a frequent complication in the intensive care unit (ICU) after adult cardiac surgery. AIM: To describe frequency of hypotension in the ICU following adult cardiac surgery and its relation to the hospital outcomes. METHODS: A retrospective study of post-cardiac adult surgical patients at a tertiary academic medical center in a two-year period. We abstracted baseline demographics, comorbidities, and all pertinent clinical variables. The primary predictor variable was the development of hypotension within the first 30 min upon arrival to the ICU from the operating room (OR). The primary outcome was hospital mortality, and other outcomes included duration of mechanical ventilation (MV) in hours, and ICU and hospital length of stay in days. RESULTS: < 0.001, for all). CONCLUSION: Hypotension upon anesthesia-to-ICU drop-off is more frequent than previously reported and may be associated with adverse clinical outcomes.

Cengic et al. (2020) conducted a cohort in Adult non-transplant cardiac surgery patients admitted to the ICU (n=417). Hypotension within the first 30 min upon ICU arrival from the OR (SBP < 90 mmHg or MAP < 65 mmHg) vs. No ICU hypotension within the first 30 min upon arrival from the OR was evaluated on Hospital mortality (OR 4.33, 95% CI 0.94-20.02, p=0.073). ICU drop-off hypotension occurred in 54% of post-cardiac surgery patients and was not associated with hospital mortality.
