چکیده
OBJECTIVE This study aimed to show the effects of intra-operative diltiazem infusion on flow in arterial and venous grafts in coronary artery bypass graft surgery. METHODS Hundred fourty patients with a total of 361 grafts [205 (57%) arterial and 156 (43%) venous] underwent isolated coronary surgery. All the grafts were measured by intraoperative transit time flow meter intra-operatively. Group A (n=70) consisted of patients who received diltiazem infusion (dose of 2.5 microgram/kg/min), and Group B (n=70) didn't receive diltiazem infusion. RESULTS Mean graft flow values of left internal mammary artery were 53 ml/min in Group A and 40 ml/min in Group B (P<0.001). Pulsatility index (PI) values of left internal mammary artery for Group A and Group B were 2.6 and 3.0 respectively (P<0.001). No statistically significant difference was found between venous graft parameters. CONCLUSION We recommend an effect of diltiazem infusion in increasing graft flows in coronary artery bypass graft operations.

Evaluation of Factors Influencing Liver Function Test in On-Pump Coronary Artery Bypass Graft Surgery
Background: Liver dysfunction during on-pump coronary artery bypass graft surgery (CABG) is a rare complication but is associated with significant morbidity and mortality. The ability to identify high-risk patients may be helpful in planning appropriate management strategies. We aimed to evaluate the factors influencing liver function tests during on-pump CABG.Methods: In 146 patients scheduled...

OBJECTIVE The aim of this study was to assess the coronary vascular resistance (CVR) and to analyze the flow differences through grafts in coronary artery bypass graft surgery. METHODS Between 17 June and 15 July 2005, we assessed the coronary vascular resistance profile in 10 patients undergoing coronary artery bypass graft surgery by grafting a section of saphenous vein and checking CVR dir...

Introduction: One of the important complications of peripheral venous catheters is suppurative thrombophlebitis that would be life threatening without treatment. In this report, we introduce a patient who developed purulent thrombophlebitis due to venous catheter in the upper limb after coronary artery bypass graft surgery. Multiple abscess formation was developed on her upper limb after the th...
متن کاملThe factors that affect blood and blood products usage in coronary artery graft surgery
Background: Coronary artery bypass surgery is one of the surgeries in which high blood transfusions are needed. About 20% of all surgical operations require a blood transfusion. Packed cell administration increases perioperative morbidity and mortality. In the United States, from every 1000 people, one has undergone a coronary artery bypass graft surgery, and it is estimated that around 800,000...
متن کاملIntraoperative flow measurements in gastroepiploic grafts using pulsed Doppler.
OBJECTIVE The patency of a pedicled right gastroepiploic artery (RGEA) graft can be compromised by intraoperative twists, kinks or spasms. Therefore, a systematic flow assessment was made in RGEA grafts and was compared with similar measurements made in other types of bypass conduits. METHODS Intraoperative pulsed Doppler flowmeter measurements obtained in a series of 556 consecutive patients...
