Open heart surgery: Pre-Op & Post-Op Care
Open-heart surgery requires careful management before, during, and after the procedure to ensure patient safety and successful recovery. Each stage, pre-operative, intra-operative, and post-operative care, plays an important role in preparing the patient for surgery, supporting the surgical process, and promoting proper healing afterwards.
Pre-operative Care
Pre-operative care is an important stage that helps ensure the patient is medically prepared for open-heart surgery. Before the procedure, doctors perform a comprehensive evaluation that may include blood tests, an electrocardiogram (ECG), echocardiography, chest X-ray, CT scan, or a coronary angiography to assess the heart’s structure and function. The patient’s medical history, current medications, allergies, and existing health conditions, such as diabetes, hypertension, or lung disease, are carefully reviewed.
Patients may be advised to stop certain medications, such as blood thinners, a few days before surgery to reduce the risk of bleeding. Doctors also provide guidance on fasting for several hours before surgery, usually from midnight on the day of the procedure. In addition, patients may receive counselling about the surgical process, potential risks, and expected recovery. Proper preparation, including maintaining good nutrition, stopping smoking, and following medical instructions, helps improve surgical outcomes and reduce complications.
Intra-operative Care
Intraoperative care refers to the medical management provided during the surgery itself. The patient is placed under general anaesthesia, ensuring they remain unconscious and free from pain throughout the procedure. The surgeon makes an incision in the chest, typically through the breastbone (sternum), to gain access to the heart. In many open-heart procedures, a heart–lung machine is used to temporarily take over the function of the heart and lungs, maintaining blood circulation and oxygen supply to the body while the surgeon performs the repair or replacement.
Throughout the operation, a specialised surgical team—including cardiac surgeons, anesthesiologists, perfusionists, and nurses—closely monitors the patient’s heart rate, blood pressure, oxygen levels, and other vital signs. Advanced surgical instruments and imaging techniques help ensure accuracy and safety. Once the repair is completed, the heart is restarted if it was temporarily stopped, and the chest is carefully closed after confirming stable heart function.
Post-operative Care
Post-operative care begins immediately after the surgery and focuses on recovery and prevention of complications. Patients are usually transferred to the intensive care unit (ICU), where they are closely monitored for the first 24–48 hours. Medical staff continuously track vital signs such as heart rate, blood pressure, breathing, and oxygen levels. Patients may initially require a ventilator to assist with breathing until they are fully awake from anaesthesia.
Pain management, wound care, and medications such as antibiotics, blood thinners, and heart-supporting drugs are provided to promote healing and prevent infection or blood clots. Gradually, patients are encouraged to begin light movements and breathing exercises to improve circulation and lung function. Most patients remain in the hospital for about 5 to 10 days, depending on their recovery progress. After discharge, cardiac rehabilitation, lifestyle changes, regular follow-up visits, and adherence to prescribed medications are essential to support long-term heart health and successful recovery.
