Randomized Controlled Trial Clinical Trial
Determination of the analgesic dose-response relationship for epidural fentanyl and sufentanil with bupivacaine 0.125% in laboring patients.
To establish the analgesic effective doses as defined as a visual analog pain scale (VAS) of at least 10 for 95% of parturients (ED95) receiving either epidural fentanyl or sufentanil with bupivacaine 0.125% for labor analgesia. ⋯ Epidural analgesia with fentanyl and sufentanil in bupivacaine 0.125% behaves in a dose-response fashion allowing for the determination of equipotent dose of each.

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 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.
