INTRODUCTION Hyperlactatemia during cardiopulmonary bypass is relatively frequent and is associated with an increased postoperative morbidity. The aim of this study was to determine which perfusion-related factors may be responsible for hyperlactatemia, with specific respect to hemodilution and oxygen delivery, and to verify the clinical impact of hyperlactatemia during cardiopulmonary bypass i...
A multipurpose arterial graft holder designed for use during coronary artery bypass grafting is described. This new holder is atraumatic and holds the arterial grafts and saphenous vein graft securely during anastomosis. The use of this instrument facilitates the use of multiple arterial grafts for coronary artery bypass grafting.
Background: Different approaches are available to irrigate the arterial catheter, such as continuous and intermittent techniques. However, there is a disagreement regarding the most appropriate method. Aim: this study aimed to compare the effect of two continuous and intermittent irrigation methods on complications of arterial catheter and partial thromboplastin time (PTT) in patients with coro...
Abstract Introduction: Cardiovascular illness is the common disease in developed countries. Among of these illnesses the coronary artery failure significantly counted as a high rate of heart disease in the world. The main treatment for this condition is replacing coronary artery bypass graft (CABG) heart pump under surgical crew including skilled nurses. Objective: This study aimed to det...
An extracorporeal bypass was performed in mongrel dogs for 2 hours with or without hypertonic mannitol infusions. In animals given mannitol, the plasma osmolality was elevated maximally to 344 +/- 7.1 mOsm/L and the urine volume was maintained well during bypass. A hypertonic mannitol solution was effective in maintaining the CPAH during and after bypass, but was not effective in minimizing the...
Gaseous microemboli have been associated with post operative neurological deficits in patients undergoing cardiopulmonary bypass. Creating an optimal perfusion system that minimizes microemboli production and has enhanced abilities to sequester entrained air during the bypass procedure has been an important focus. This study examines the air-handling capabilities of a cardiopulmonary bypass cir...
Background & Aims: Metabolic acidosis can be harmful and can complicate cardiopulmonary bypass (CPB) during coronary artery bypass graft surgery. We hypothesized that the pump prime can cause this disturbance. We compared effects of Ringer solution with Ringer Lactate, two types of priming fluid in producing metabolic acidosis in patients undergoing coronary artery bypass graft (CABG) ...Materi...
The possibility that venous blood could be withdrawn through a radial artery cannula when venous pressure is high was examined in 30 patients during cardiopulmonary bypass for coronary artery bypass operation. Progressive desaturation of radial artery blood occurred when venous pressure was equal to arterial pressure. Desaturation not only increased with duration of venous obstruction but also ...
