The effect of total intravenous anesthesia on the postoperative cognitive functions of young and elderly patients after lumbar disk surgery.

Background/aim: The negative effects of surgery and anesthesia on cognitive functions and their relationships with many factors are well known. In the present study we aimed to investigate the effect of the total intravenous anesthesia (TIVA) method on the postoperative cognitive functions between young and elderly patients scheduled to undergo lumbar disk surgery.

Materials And Methods: The TIVA method was applied to 40 patients less than 65 years old (young, Group Y) and ≥65 years old (old, Group O), whose Mini Mental State Examination (MMSE) results and serum S-100 beta protein levels were compared preoperatively and postoperatively at the 24th hour.

Hemodynamic effects of chest-knee position: comparison of perioperative propofol and sevoflurane anesthesia.

Background/aim: There are limited data in the literature investigating the effects of anesthetic agents on cardiac output used in the chest-knee position. The aim of this study is to compare the effects of inhalation and total intravenous anesthesia on cardiac output in patients undergoing lumbar discectomy in the chest-knee position.

Materials And Methods: Forty patients undergoing discectomy in the chest-knee position were allocated to 2 groups.

Intraoperative neurophysiological monitoring during surgery for tethered cord syndrome.

Aim: The tethered cord syndrome refers to a variety of lesions that can cause the conus medullaris to be low-lying or incapable of movement within the spinal canal. Permanent or temporary neurological complications were reported following surgical release. In this report, peri- and postoperative results in cases with tethered cord syndrome that were followed by multimodal intraoperative neurophysiological monitoring (MIONM) methods are presented.
