Summary

Early extubation after cranial surgery is safe and avoids routine CT scans. Patients not extubated within one hour require early CT due to increased risk of neurosurgical intervention.

Area of Science:

  • Neurosurgery
  • Critical Care Medicine
  • Radiology

Background:

  • Routine postoperative computed tomography (CT) is common after elective cranial surgery.
  • This study evaluated an alternative management strategy.
  • The strategy involved early extubation and close neurological monitoring without routine CT.

Purpose of the Study:

  • To determine the safety of early extubation and close neurological monitoring post-cranial surgery.
  • To compare the rate of postoperative emergency neurosurgical intervention with published data.
  • To assess if routine postoperative CT can be safely omitted.

Main Methods:

  • Prospective analysis of 492 patients undergoing elective cranial surgery.
  • Targeted extubation within one hour of skin closure.
  • Computed tomography (CT) was reserved for cases with unexpected neurological findings within 48 hours.

Main Results:

  • 95.3% of patients were extubated within one hour.
  • Only 8.7% of patients required emergency CT within 48 hours.
  • The rate of recraniotomy for hemorrhage was 0.8%, and 0.8% required external ventricular drain (EVD) placement.

Conclusions:

  • Early extubation with close neurological monitoring is a safe alternative to routine postoperative CT.
  • Delayed extubation (over one hour) was significantly associated with an increased risk of requiring emergency neurosurgical intervention (13.0%).
  • Selective CT based on clinical assessment is effective, avoiding routine imaging and its associated risks and costs.
