ICU care standards

Open heart surgery is a major procedure that requires expert post-operative care to ensure a smooth and successful recovery. The Intensive Care Unit (ICU), particularly the Cardiothoracic Intensive Care Unit (CTICU), plays a crucial role in monitoring patients during the first few hours and days after surgery. At Aster RV Hospitals, under the guidance of experienced specialists like Dr. Divakar Bhat, patients receive comprehensive critical care supported by advanced technology and evidence-based protocols.

Waking up after surgery Following surgery, patients are transferred to the ICU while still under the effects of anesthesia. Most patients wake up either later the same day or early the following morning. Initially, a breathing tube connected to a mechanical ventilator helps support breathing until the patient is fully awake and capable of breathing independently.

The ICU team continuously monitors the patient’s condition and removes the breathing tube once the patient demonstrates adequate respiratory effort, stable oxygen levels, and sufficient alertness.

Continuous monitoring for recovery During the early recovery phase, several monitoring devices are used to ensure patient safety:

  • Intravenous and arterial lines monitor blood pressure and deliver medications.
  • Central venous lines help measure heart pressures and obtain blood samples.
  • A urinary catheter allows accurate monitoring of kidney function and urine output.
  • Frequent blood sugar checks are performed, as surgical stress can temporarily elevate glucose levels, even in non-diabetic patients.
  • Electrocardiograms (ECG), chest X-rays, and laboratory tests help evaluate heart function, lung expansion, and blood clotting status.

Most monitoring lines are safely removed within the first one or two days after surgery. Immediate ICU management

Upon arrival in the ICU, patients receive mechanical ventilation with standard settings while the healthcare team focuses on maintaining stable circulation and organ function.

Initial care includes:

  • Airway protection through endotracheal intubation
  • Mechanical ventilation support
  • Continuous cardiac output and blood pressure monitoring
  • Chest X-ray to verify the placement of tubes and assess lung expansion
  • ECG monitoring for early detection of heart muscle ischemia
  • Blood coagulation assessment following reversal of blood thinners used during surgery
Care during the first four hours The first four hours after surgery are critical for recovery.

Ventilator management As the patient’s condition improves, ventilation is gradually transitioned from mandatory support to pressure support mode while oxygen concentration is reduced according to tolerance.

Temperature control Patients are allowed to return to normal body temperature naturally, with active warming measures used only when necessary.

Hemodynamic support Blood pressure and circulation are carefully managed with medications that support heart function and vascular tone. ICU specialists remain vigilant for complications such as hypotension or cardiac tamponade.

Fluid and electrolyte management Balanced intravenous fluids help maintain circulation, while electrolyte levels—particularly potassium and magnesium—are closely monitored and corrected to reduce the risk of abnormal heart rhythms.

Readiness for extubation Most uncomplicated patients undergoing coronary artery bypass graft (CABG) surgery are ready for removal of the breathing tube within four to six hours after surgery, provided they meet the following criteria:

  • Stable blood pressure and heart function
  • Normal body temperature
  • Adequate level of consciousness
  • Effective spontaneous breathing
  • Normal oxygen levels
If extubation is delayed, the ICU team evaluates factors such as sedation, body temperature, cardiac stability, and respiratory function before proceeding safely.

Managing post-operative respiratory recovery

Early mobilization, breathing exercises, chest physiotherapy, and careful pain management are essential components of ICU care. These measures help reduce the risk of lung infections, improve oxygenation, and promote faster recovery.
