Predictive Factors for Hypotension Associated With Supine-to-Prone Positional Change in Patients Undergoing Spine Surgery.
Positional change during general anesthesia can cause hypotension. The objective of this retrospective study was to determine predictive factors for hypotension associated with supine-to-prone positional change in spinal surgery patients. ⋯ Increased effect-site concentration of remifentanil, preoperative use of beta-blocker, and high MAP in the supine position were predictive factors for hypotension associated with supine-to-prone positional change in spinal surgery patients.

Glucose and Lactate Concentrations in Cerebrospinal Fluid After Traumatic Brain Injury.
Studies in which brain metabolism has been monitored using microdialysis have indicated decreases in cerebral glucose concentration and increases in lactate concentration in patients with traumatic brain injury (TBI). However, few data are available on glucose and lactate concentrations in the cerebrospinal fluid (CSF) of TBI patients. This study investigates the relationship between CSF glucose and lactate concentrations and outcomes after TBI. ⋯ Low CSF glucose/lactate ratio is observed in nonsurvivors after severe TBI and may have prognostic value.
