What are some indications for CABG?

The chief anatomical indications for CABG are the presence of triple-vessel disease, severe left main stem artery stenosis, or left main equivalent disease (ie, 70 percent or greater stenosis of left anterior descending and proximal left circumflex artery)—particularly if left ventricular function is impaired.

Which type of anesthesia would be used during a CABG procedure?

You stay under general anesthesia (fully asleep) during the duration of the surgery. You will be maintained under general anesthesia while the success of the surgery is monitored, making sure the bypass is allowing blood to reach the heart.

What are the indications for open heart surgery?

You may need open-heart surgery if you have one of these heart conditions:

  • Arrhythmias, including atrial fibrillation.
  • Congenital heart defects, such as atrial septal defect (hole in the heart) or hypoplastic left heart syndrome (underdeveloped heart structures).
  • Coronary artery disease.
  • Heart failure.

What medications are used during CABG?

Coronary Artery Bypass Grafting Medication: Anxiolytics, Benzodiazepines, Opioid Analgesics, Anesthetic Agents, Neuromuscular Blockers, Nondepolarizing, Anticoagulants, Hematologic.

When is CABG preferred over PCI?

CABG is the preferred option for left main disease with 2- and 3-vessel disease and a SYNTAX score >32. CABG is also the preferred option even in the presence of a lower SYNTAX score when multiple complex lesions are present and PCI remains technically limited to achieve complete revascularization.

What anesthetic is used for open-heart surgery?

Isoflurane. Isoflurane is a chemical isomer of enflurane and is currently one of the most commonly used volatile anesthetic in cardiac surgery. Its popularity has stemmed partly from its minimal cardiac effects when compared with older agents.

What medication is commonly given during the induction of most cardiovascular surgeries?

Propofol, etomidate, and ketamine are the intravenous (IV) sedative-hypnotic agents commonly used to induce general anesthesia (table 1), while adjuvant agents (eg, opioids, lidocaine, midazolam) are often used to supplement the effects of the primary sedative-hypnotic induction agent (table 2).

When is bypass surgery recommended?

Your doctor may recommend heart bypass surgery if your coronary arteries become so narrowed or blocked that you run a high risk of a heart attack. Your doctor will also recommend bypass surgery when the blockage is too severe to manage with medication or other treatments.

Why is omeprazole given before surgery?

Oral omeprazole 20 mg administered on the night prior to surgery will improve the gastric environment at the time of induction of anaesthesia, thus reducing the potential risk of pneumonitis, should the aspiration of gastric contents occur following the induction of anaesthesia.
