We consider the effect of the number of previous interactions between the anesthesia provider and a single neurosurgeon during neurosurgical procedures ("familiarity") and occurrence of an interval ≥15 min from the end of surgery (i.e., dressings applied) to tracheal extubation ("prolonged extubation") during subsequent glioma procedures by that neurosurgeon. The value of 15min is a threshold at which post-case activity by non-anesthesia personnel in the operating room ends. ⋯ Lack of familiarity between the anesthesia provider and neurosurgeon during previous anesthetics is associated with prolonged tracheal extubation following intracranial glioblastoma surgery.
