Nursing neurologic assessments after cardiac operations

Area of Science:

• Neurology
• Cardiology
• Critical Care Medicine

Background:

• Limited research exists on immediate postoperative neurologic status after cardiac operations.
• Standardized nursing neurologic evaluations can track early changes.

Purpose of the Study:

• To describe the sequence of neurologic changes in the early hours after cardiac surgery.
• To identify factors influencing postoperative neurologic recovery.

Main Methods:

• Prospective study using the Neurologic Intensive Care Evaluation (NICE) in the ICU.
• Serial neurologic assessments for up to 24 hours postoperatively.
• Evaluation of preoperative, intraoperative, and NICE score effects on outcome.

Main Results:

• Brainstem reflexes returned at 1.4 hours; full alertness at 5.1 hours in patients without deficits.
• New deficits, complex surgeries, older age, and higher cardiovascular risk prolonged recovery.
• Time to highest NICE score predicted intubation duration but weakly predicted other outcomes.

Conclusions:

• Standardized, serial nursing neurologic assessments offer insights into the immediate postoperative period.
• These assessments can aid in early identification of patients at risk for adverse outcomes.
