To evaluate a large series of elective lumbar spine surgical procedures by a single surgeon whose patients were all offered spinal anesthesia. ⋯ Spinal anesthesia is an effective alternative to general anesthesia for lumbar spine surgery and has a reduced rate of minor complications.

To determine the differences in the onset time and duration of motor block produced by lidocaine 1% and lidocaine 2% via a quantitative and objective method, the measurement of compound muscle action potentials (CMAPs). ⋯ The present study describes a technique that can be used in vivo to objectively measure the speed of onset and duration of local anesthetic-induced motor blockade. Although statistically not different, lidocaine 2% demonstrated a faster onset and longer duration of ulnar nerve motor block than lidocaine 1%.

To evaluate heart rate (HR) variability in the prone position with power spectral heart rate (PSHR) analysis during spinal and general anesthesia. ⋯ The association of less change in LFa activity and preservation of BP on assumption of the prone position in patients during low spinal anesthesia suggests better preservation of autonomic nervous system compensatory mechanisms during low spinal anesthesia than with general anesthesia.

Separation of the lungs with a double-lumen endobronchial tube facilitates the surgical approach and protects the bronchial system from contamination by pus or blood from the operated lung. We report a case of a 49-year-old man who suffered a gram-negative pneumonia requiring mechanical ventilatory support and prolonged hospitalization after pulmonary resection. Contamination of the ventilated-dependent lung was documented intraoperatively. Current information on postoperative infectious complications and preventive measures are discussed.
