Randomized Controlled Trial Clinical TrialSpinal (subarachnoid) morphine for off-pump coronary artery bypass surgery.
To study the effects of 8 microg/kg preoperatively administered intrathecal morphine sulfate on extubation time, postoperative pulmonary function, and postoperative analgesia after off-pump coronary artery bypass grafting (OPCAB). ⋯ Intrathecal morphine provided superior quality of analgesia that translated into better maintenance of postoperative lung volume determined by spirometry. This analgesic method also facilitated earlier tracheal extubation without any major respiratory or neurologic complications.

Comparative StudyMitral valve operations through standard and smaller incisions.
Evaluate the operative results of mitral valve repair (MVV) and mitral valve replacement (MVR) performed through standard and smaller incisions. ⋯ The mortality rate for MV operations is concentrated among a few diagnoses. In some patients surgery may be approached safely through smaller incisions without introducing new elements of operative risk.

Immediate Extubation after Aortic Valve Surgery Using High Thoracic Epidural Anesthesia.
Abstract Purpose: Fast-track anesthesia has gained widespread use in cardiac centers around the world. No study has focused on immediate extubation after aortic valve surgery. This study examines the feasibility and hemodynamic stability of immediate extubation after simple or combined aortic valve surgery using thoracic epidural anesthesia. ⋯ There were no complications related to TEA. Conclusions: Immediate extubation is feasible after aortic valve surgery with high thoracic epidural analgesia and maintenance of hemodynamic stability throughout surgery. Immediate extubation after aortic valve surgery is a promising new path in cardiac anesthesia.

Controlled Clinical TrialExperience on the way to totally endoscopic atrial septal defect repair.
Remote-access perfusion and robotics have enabled totally endoscopic closure of atrial septal defect (ASD) and patent foramen ovale (PFO). We report on a stepwise approach to a totally endoscopic procedure. ⋯ The implementation of robotic totally endoscopic closure of ASD or PFO in a heart surgery program seems to be safe. An intermediate step of performing the operations through minithoracotomy, adapting to remote access perfusion systems, and gaining experience in other robotic cardiac surgical procedures seems worthwhile. Learning curves are apparent, and adequate defect closure does not seem to be compromised by the totally endoscopic approach.

Controlled Clinical TrialIn vivo and in vitro evaluation of the heparin management test versus the activated coagulation time for monitoring anticoagulation level in aprotinin-treated patients during cardiac surgery.
Monitoring whole blood anticoagulation therapy with the activated coagulation time (kaolin ACT) and the heparin management test (HMT) were correlated in vivo with the plasma anti-activated factor X (anti-Xa) heparin concentration in patients who received variable doses of aprotinin and in vitro in the presence of increasing concentrations of aprotinin. ⋯ The abilities of the HMT and the kaolin ACT to measure anticoagulation effects were not significantly different. Aprotinin prolonged both the kaolin ACT and the HMT time in a dose-dependent manner, but the HMT was significantly less affected by aprotinin in vivo. The HMT is a reliable alternative to measuring the ACT in cardiac operations and may offer greater accuracy in aprotinin-treated patients.
