Brief summary
Airway management of patients undergoing thermal coagulation of the Gasserian ganglion is very delicate. This is because of the specific operation site and moreover patients should recover quickly from anesthesia to follow verbal intraoperative commands of the surgeon. Endotracheal intubation or laryngeal mask of course hinders the patient from speaking. An obvious alternative airway management, as performed in this preliminary study, is a nasopharyngeal placed tube. The purpose of the present study is to objectify the gas exchange in patients during this new ventilation technique.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Blood gas exchange | Before and during the neurosurgical intervention | Blood gas analyses will be determined at three time points perioperatively. The first measurement, at base line, will be performed preoperatively, the second one after puncture of the Gasserian ganglion and the third during the thermal coagulation of the Gasserian ganglion. |
Secondary
| Measure | Time frame |
|---|---|
| SpO2 oxygen saturation (pulse oximeter) | Before and during the neurosurgical intervention |
| Hemodynamic parameters | Before and during the neurosurgical intervention |
