To confirm the relationship between bevel orientation, catheter direction, and radiopaque contrast spread in the lumbar region. ⋯ A strong relationship exists between bevel orientation and catheter direction; however, catheter position does not reliably predict the direction in which the injected fluid spreads in all cadavers.
-
To validate intraoperative pulse hemoglobin (SpHb) measurements in anesthetized patients with large forearm temperature - fingertip temperature gradients. ⋯ SpHb measured at fingertip was significantly affected by the perfusion state, with lower perfusion associated with lower SpHb. Thermoregulatory vasoconstriction affects measurement of SpHb.
-
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.

Randomized Controlled Trial
Prewarming of the i-gel facilitates successful insertion and ventilation efficacy with muscle relaxation: a randomized study.
To determine if prewarming of the i-gel (Intersurgical, Wokingham, United Kingdom) improves insertion and ventilation efficacy with muscle relaxation in patients undergoing elective surgery. ⋯ Prewarming the i-gel to 42°C demonstrated a higher successful ventilation initiation.
