The effect of pulsatile versus non-pulsatile flow during cardiopulmonary bypass on cerebral oxygenation: A randomized trial.

Background: The present study aims to compare regional oxygen supply determined by Near-Infrared Spectroscopy in the course of pulsatile perfusion with non-pulsatile perfusion during cardiopulmonary bypass in patients undergoing valvular heart surgery.

Methods: In this prospective randomized single-blinded trial, we enrolled adult subjects aged 18-65 years scheduled for elective valvular heart repair/replacement surgery with non-stenotic carotid arteries, employing a consecutive sampling method. Eligible patients were then randomly assigned in a 1:1 ratio to pulsatile or non-pulsatile perfusion during aortic cross-clamp.

Modified translaryngeal tracheostomy for ventilator-dependent cardiac patients: A pilot of nonrandomized study.

Introduction: A significant proportion of ventilator-dependent cardiac patients need tracheostomy during intensive care unit (ICU) stay. Three different methods including traditional (surgical), percutaneous dilatation tracheostomy, translaryngeal tracheostomy (TLT), and classical Fantoni method have been developed. In this study, modified translaryngeal tracheostomy (MTLT) has been introduced to reduce and correct the technical difficulty of classical TLT through the larynx.

Suprasternal innominate artery cannulation for reoperative aortic surgery: a technical note.

Suprasternal cannulation of the innominate artery in aortic reoperations may be useful in specific situations. Over a period of 3.5 years, 9 patients (6 males, average age = 49.

Intravenous patient-controlled remifentanil versus paracetamol in post-operative pain management in patients undergoing coronary artery bypass graft surgery.

Background: Pain management after cardiac surgery has been based on parenteral long-acting opioids such as morphine. The other alternatives are paracetamol and remifentanil.

Objectives: In this prospective, double-blind, randomized study, we compared the efficacy of intravenous patient-controlled analgesia (IV-PCA) paracetamol and remifentanil for post cardiac surgery pain relief.

The Effects of Positive Airway Pressure Ventilation during Cardiopulmonary Bypass on Pulmonary Function Following Open Heart Surgery.

Background: Intrapulmonary shunt as a result of atelectasis following cardiac surgeries is an important and common postoperative complication that results into pulmonary dysfunction typically lasting more than a week following surgery. Different methods have been provided to prevent these complications.

Objectives: In order to prevent postoperative pulmonary complications, investigation of the effectiveness of continuous positive airway pressure (CPAP) and intermittent mandatory ventilation (IMV) during cardiopulmonary bypass (CPB) in patients undergoing coronary artery bypass grafting (CABG).
