Perioperative care in elderly cardiac surgery patients

Area of Science:

• Geriatric Medicine
• Cardiovascular Surgery
• Anesthesiology

Background:

• Aging leads to progressive cellular degeneration, impairing physiological responses to surgical stress in elderly patients (≥ 75 years).
• Older adults have a narrower safety margin during surgery, increasing risks of perioperative complications.

Purpose of the Study:

• To compare perioperative complications in patients aged 75 years and older undergoing cardiac surgery with those in younger patients.
• To evaluate the impact of a standardized perioperative care protocol on outcomes in elderly cardiac surgery patients.

Main Methods:

• A retrospective study involving 1446 patients at the Silesian Centre for Heart Diseases (2009-2014).
• Implementation of a standardized perioperative care protocol for seniors to minimize complications, mechanical ventilation, and delirium.
• Comparison of outcomes between patients aged ≥ 75 years and younger patients.

Main Results:

• The mean duration of mechanical ventilation was comparable between elderly (≥ 75 years) and younger patients (13.8 hours).
• In-hospital mortality was significantly higher in the elderly group (3.8%) compared to younger patients.
• Elderly patients undergoing cardiac surgery exhibited more comorbidities, impacting hospital stay duration and mortality.

Conclusions:

• The standardized perioperative care protocol successfully reduced mechanical ventilation duration and postoperative delirium in elderly patients (≥ 75 years).
• Despite improved ventilation and delirium rates, elderly cardiac surgery patients face significantly higher in-hospital mortality due to increased comorbidities.
