Comparing a New Technique of Combining Carbon-dioxide With Electrocautery With Usual Technique of Stand-alone Electrocautery for Taking Down Left Internal Mammary Artery for Coronary Artery Bypass(CABG)

The goal of this study is to compare the efficacy of a new harvesting technique for an arterial conduit(LIMA - Left Internal Mammary artery) in patients undergoing Coronary artery bypass grafting. The researcher will compare the

1. Time taken to harvest the artery 2. Flow of blood between the two techniques

About this study

Following consultation to our department, after a detailed history and clinical examination,patients with CAD, being planned for CABG, will be subjected to a detailed pre-op Echocardiogram and coronary angiogram. After necessary pre-op assessment, patient will be taken up for the surgery. Invasive monitoring will be done.

Following dissection of LIMA by the above mentioned technique, flow of blood from the harvested LIMA, for one whole minute is noted. The operative time required for the dissection of LIMA will be noted and entered.

The data between the two techniques will be compared statistically.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Elective CABG
  • Hemodynamically stable CAD patients

Exclusion criteria

  • Re-operation, previous sternotomy (where LIMA is already dissected)
  • concomitant valve operation, ventricular aneurysm resection
  • other additional major cardiac procedures
  • Patients with chronic obstructive pulmonary disease

Treatment and study plan

Modified Carbo-dissection Technique

Procedure

This technique comes the C02 blower with electrocautery. Thereby, producing vasodilatation due to the gas and dissection aided by the electrocautery.

Conventional Arm

Procedure

This technique uses only the electrocautery as conventional model

Primary outcomes

  1. Operative time

    Time frame: 10-20 min

    Time taken to perform the harvesting of the LIMA

  2. Blood flow/min

    Time frame: 1 min

    Post dividing of the LIMA: blood from the LIMA is measured for 1 min
