To determine whether postoperative cardiac surgery patients who are sedated with dexmedetomidine have fewer atrial arrhythmias, and whether dexmedetomidine is associated with fewer renal and more gastrointestinal (GI) complications. ⋯ Dexmedetomidine use after cardiac surgery was associated with a lower incidence of atrial arrhythmias.

Case Reports
Incidental discovery of a partial anomalous pulmonary venous connection in the surgical critical care unit.
Routine chest roentgenogram to confirm catheter placement in a postsurgical patient showed a left-sided internal jugular central venous catheter that did not appear to cross the midline. Arterial blood gas samples showed greater oxygenation from the central catheter as compared with the peripheral arterial sample. However, a transduced waveform showed a venous tracing and pressure. Computed tomographic scan of the thorax without intravenous contrast showed a partial anomalous pulmonary venous connection with drainage of the left upper lobe pulmonary vein into the innominate vein.

To identify risk factors for coagulopathy in patients undergoing liver resection. ⋯ Epidural anesthesia is feasible in patients scheduled for liver resection. Caution should be observed for patients with extended resection (≥3 segments) and increased postoperative lactate. In patients with preexisting liver disease, epidural catheters should be avoided.

Two cases of vocal cord closure, which was responsible for acute intraoperative impairment of mechanical ventilation in two patients with entropy-controlled depth of anesthesia, are reported. Administration of low-dose neuromuscular blocking drug was associated with immediate vocal cord relaxation and restoration of efficient mechanical ventilation.

Observational Study
Observational study of Mallampati changes after prone spinal surgery.
To evaluate airway changes in patients undergoing surgery in the prone position. ⋯ Modified Mallampati scores increased in the majority of patients after spinal surgery in the prone position.
