World’s First Awake Cardiac Bypass Surgery
Dr Vivek Jawali, chief cardiovascular surgeon along with his team at Wockhardt Heart Hospital at Bangalore have set a global benchmark by performing the first coronary bypass surgery along with an aortic valve replacement without using general anaesthesia or ventilator support while the patient was on a heart lung machine.The technique of high thoracic epidural analgesia is a highly precision based methodology which involves injection of micro doses of local anaesthetic in the epidural space around the spinal cord which anaesthetises only the chest region while the rest of the system is fully awake.
1. Insert an epidural catheter into the patient the day before the operation.
2. Patient to theatre. Administer a test dose of the epidural below the nape of the neck.
3. Give the patient the full dose and wait 20 minutes for all sensation from the chest to be blocked. Test by prodding the patient’s skin with a needle.
4. Open breastbone using electric saw.
5. Main surgery.
6. Close the breastbone with steel wire and close skin.
7. Transfer patient to intensive care.Aren’t the 7 easy steps just great? And awake open heart surgery, too intense for me.
