A method for epiduroscopy and spinaloscopy. Presentation of preliminary results.
A method for endoscopic observation of the epidural space, epiduroscopy, and the subarachnoid space, spinaloscopy, in the lumbar region is described using the Olympus Selfoscope SES 1711 S. The preliminary results of 30 consecutive attempts at epiduroscopy on randomly chosen autopsy cases, with 28 successes, are presented. Five spinaloscopies were performed on the same material. The results justify the conclusion that epiduroscopy and spinaloscopy are methods that can be used for study of individual variation of the contents of the lumbar epidural and subarachnoid spaces.

Comparative StudyEffect of anaesthesia on respiratory function after major lower extremity surgery. A comparison between bupivacaine spinal analgesia with low-dose morphine and general anaesthesia.
Postoperative pulmonary function was studied in 16 patients undergoing total hip or knee arthroplasty. Their mean age was 65 years. Half of them received spinal analgesia (22.5 mg bupivacaine + 0.3 mg morphine) and the other half underwent general anaesthesia with halothane-nitrous oxide. ⋯ Simultaneously, PA-ao2 was increased, and Pao2 remained reduced despite increased alveolar ventilation (lowered PaCo2). In the general anaesthesia group FVC, FRC and CC were also reduced, but the gas distribution index remained at the awake level and blood gases were unaltered. It is suggested that the slight hypoventilation in the spinal analgesia group early after surgery may have contributed to impaired gas distribution and ventilation-perfusion matching later postoperatively.
