Brief Summary
The purpose of this study is to assess the effect size and variability of dural tension measured as intracranial pressure (ICP) below the dura of the surgical field in patients undergoing elective supra-tentorial surgery for brain neoplasms in patients alternatively ventilated with traditional high-volume-no-PEEP ventilation and protective low-volume-low-PEEP ventilation.

Outcome Measures
Primary Outcomes (1)
Intracranial pressure measured in mmHg
Primary endpoint: to assess the effect size and variability of dural tension measured as intracranial pressure (ICP) below the dura of the surgical field in patients undergoing elective supra-tentorial surgery for brain neoplasms in patients alternatively ventilated with traditional high-volume-no-PEEP ventilation and protective low-volume-low-PEEP ventilation.
Outcome 1 is assessed before the incision of dura mater (mean 1 hour).
Secondary Outcomes (1)
Dural tension measured by a two point scale (acceptable/unacceptable).
Outcome 2 is assessed before the incision of dura mater (mean 1 hour).
Study Arms (2)
Traditional to protective ventilation
OTHERTraditional ventilation will be set with 9 ml/kg with predicted body weight of tidal volumes and no PEEP. Arterial CO2 partial pressure will be maintained between 30 and 35 mmHg. After intracranial pressure measurement ventilation will be switched to protective.
Protective to traditional ventilation
OTHERProtective ventilation will be set with 7 ml/kg tidal volume, 5 cm H2O PEEP, and 0.4 inspired O2 fraction (FiO2). Arterial CO2 partial pressure will be maintained between 30 and 35 mmHg. After intracranial pressure measurement ventilation will be switched to traditional.
Interventions
Traditional ventilation will be set with 9 ml/kg with predicted body weight of tidal volumes and no PEEP and switched to protective ventilation after intracranial pressure measurement.
Protective ventilation will be set with 7 ml/kg tidal volume, 5 cm H2O PEEP, and 0.4 inspired O2 fraction (FiO2), and switched to traditional ventilation after intracranial pressure measurement.
