CORRELATION BETWEEN EJECTION FRACTION AND CORONARY SINUS BLOOD FLOW DURING OFF-PUMP CORONARY ARTERY BYPASS GRAFTING SURGERY.

Introduction: Many studies have shown that coronary artery bypass grafting (CABG) increases the survival rate of patients, but the effect of bypass grafting on cardiac function is still a matter of debate.

Objective: The objective of our study was to determine: a. To what extent can the change in coronary sinus flow be used as an intraoperative criterion for the assessment of adequate revascularization.

SUCCESSFUL EMERGENCY ARTERIAL EMBOLIZATION FOR MASSIVE GASTRODUODENAL BLEEDING IN HIGH-RISK PATIENT. CASE REPORT.

Massive upper gastrointestinal bleeding still remains a challenge, which can cause serious clinical problems especially in high-risk patients. We present a rare case of patient with complex pathology successfully managed by endovascular treatment. A 78-year-old man with a medical history of chronic bronchitis, several minor strokes, type II diabetes, a 30-year history of smoking, and a family history of cardiovascular disease, presented with severe pain on the left side of his chest radiating to his left arm.

FEASIBILITY AND EFFECTIVENESS OF GENERAL ANESTHESIA WITH OPIOIDS VERSUS OPIOID-FREE ANESTHESIA PLUS TRANSVERSUS ABDOMINIS PLANE BLOCK ON POSTOPERATIVE OUTCOMES AFTER MINI GASTRIC BYPASS SURGERY.

Opioid-free anesthesia (OFA) is increasingly used at present in surgical practice by many hospitals as a new and very promising anesthesiologic regimen. This study aimed to compare the efficacy of standard general anesthesia with opioids with so-called opioid-free anesthesia on postoperative outcomes of patients who underwent gastric bypass surgery. This randomized, single-blind clinical study enrolled 103 patients scheduled for elective gastric bypass surgery.

EFFECT OF INHALED OXYGEN CONCENTRATION ON PULMONARY GAS EXCHANGE DURING OFF-PUMP CORONARY BYPASS GRAFTING.

Aim of study - supra-physiologic level of PaO2, securing oxygen reserves and preventing perioperative hypoxia, may offset the reduced oxygen delivery during cardiac surgery. However, high FiO2 will speed up gas absorption in low V/Q regions, promote atelectasis formation and increase pulmonary shunt fraction. PaO2/FiO2, P(a-Et)CO2 and PEtCO2/PaCO2 are the variables linked to CO2 and O2 exchange impairment.

Minimal fixed flow anesthesia for off-pump coronary artery bypass surgery: A parallel randomized trail.

Objectives: The aim of the present study was to test a safety of a fixed minimal (0.5 l/min) fresh gas flow (FGF) anesthesia as a method ensuring adequate oxygenation during off-pump coronary artery bypass grafting operations.

Design: A randomized, prospective study.
