A Comparative Study Between Conventional & Modified Carbo-dissection Techniques for LIMA Harvesting in CABG Patients

The carbo-dissection technique is performed using an improvised instrument that combines an electrocautery pencil (ValleylabTM Force FX electrocautery Pencil, Covidien, USA) with a CO2 mister blower (PerfX® Heart Lung pack Blower/Mister Kit, B L Lifesciences, Noida, India) and the instruments are fixed together using silk ties.The electrocautery is used in the coagulation mode at a setting of 10 to 15. The C02 flow is set at 2 to 3 litres/minute. Saline flow is adjusted to a level that does not hinder the effective coagulation but still prevents drying and desiccation of the tissues. Following the dissection of LIMA by the techniques mentioned above, blood flow from the harvested LIMA for one whole minute was noted(1 min post division of LIMA). The operative time required for LIMA dissection was also noted and entered. Patient's s demographic data were also collected and entered.
