Abstract
The statistical data in this paper suggest that the number of neurosurgical operations on elderly patients will further increase and halothane anesthesia will maintain its popularity until the advent of a better anesthetic agent. The specificity of elderly patients and important preoperative preparations are discussed. Pre and postoperative complications were most frequently found in the cardiorespiratory system. PaO2 decreased postoperatively, whereas PaCO2 was often lower than normal. Good communication between the anesthesiologist and the neurosurgeon is fundamental for safe neuroanesthesia on problematic elderly patients.
