Randomized Controlled Trial Clinical Trial
Postoperative effects of low-dose intrathecal morphine in coronary artery bypass surgery.
Intrathecal morphine has been used in hopes of providing long-lasting postoperative analgesia in patients after cardiac surgery. The aim of this study was to evaluate the effects of 7 micro/kg intrathecal morphine administration in coronary bypass surgery in the postoperative period. ⋯ Intrathecal morphine provided effective analgesia, earlier tracheal extubation and less ICU length stay after on-pump coronary bypass surgery. The influence on ICU length of stay requires further evaluations.

Randomized Controlled Trial Clinical Trial
On-pump beating heart versus hypothermic arrested heart valve replacement surgery.
Comparison of neurological parameters in patients undergoing prosthetic heart valve replacement with two operating techniques-either cardioplegic arrest of the heart under hypothermic cardiopulmonary bypass (CPB) or the heart beating on normothermic bypass, with or without cross-clamping the aorta, without cardioplegic arrest. methods: Fifty valvular surgery patients were randomly assigned into three groups. Sixteen patients underwent beating heart valve replacement with normothermic bypass without cross-clamping the aorta, 17 patients underwent the same procedure with cross-clamping the aorta and retrograde coronary sinus perfusion, and the remaining 17 patients had conventional surgery with hypothermic bypass and cardioplegic arrest. ⋯ There is no difference regarding neurological monitoring results between on-pump beating heart and hypothermic arrested heart valve replacement surgery. Also no significant difference was encountered among the groups regarding the clinical outcomes.

Comparative Study Clinical Trial
Neurocognitive functions after beating heart mitral valve replacement without cross-clamping the aorta.
Although neurologic outcome after cardiac surgery is well-established, neurocognitive functions after beating heart mitral valve replacement still needs to be elucidated. The aim of this study was to compare preoperative and postoperative neurocognitive functions in patients who underwent beating heart mitral valve replacement on cardiopulmonary bypass without cross-clamping the aorta. ⋯ The technique of mitral valve replacement with normothermic cardiopulmonary bypass without cross-clamping of the aorta may be safely used for majority of patients requiring mitral valve replacement without causing deterioration in neurocognitive functions.

Clinical Trial
Risk factors for prolonged stay in the intensive care unit and on the ward after cardiac surgery.
Prolonged length of stay (LOS) after cardiac surgery has been associated with poor outcome and a considerable expenditure of health care resources. As our patient's demographics are changing, a continuing evaluation of the preoperative and intraoperative variables affecting LOS in the intensive care unit (ICU) and on the floor remains important. ⋯ In this series of 426 consecutive patients, we have identified several perioperative risk factors associated with prolonged hospitalization that can help clinicians in their preoperative patient counseling, risk stratification, and selection. However, the most obvious use of these results is in allowing decision makers to implement specific strategies that would best allocate resources depending on the risk profile of cardiac patients.

We present a rare case of bullet embolism from the left brachiocephalic vein to the right ventricle, following a chest gunshot wound, in a 56-year-old soldier. The bullet was accidentally discovered on a systematic chest X-ray. The bullet was very close to the tricuspid subvalvular apparatus and was about to come out from the ventricle. We removed it under cardiopulmonary bypass.
