  • Title: Sitting prone position for the posterior surgical approach to the spine and posterior fossa.
    Author: Cook AW, Siddiqi TS, Nidzgorski F, Clarke HA.
    Journal: Neurosurgery; 1982 Feb; 10(2):232-5. PubMed ID: 7070620.
    Abstract:
    The sitting prone position is compared with the standard laminectomy prone position and the sitting up position for posterior fossa surgery. We measured central venous pressure and airway pressure with the patient in different positions to determine the comparative efficacy of the sitting prone position. On a linear average, the central venous pressure increased by 6.83 cm H2O and the airway pressure increased by 3.16 cm H2O when the patient was changed from the supine to the standard prone position under general anesthesia; with a change from the standard prone position to the sitting prone position, the central venous pressure decreased by 10.45 cm H2O and the airway pressure decreased by 3.66 cm H2O. However, comparing the sitting prone position for posterior fossa surgery with the sitting up position, there was no statistically significant difference in central venous or airway pressure.
