Airway Management for Trigeminal Thermal Coagulation

Not Applicable

Completed

• Conditions: Airway Management
• Interventions: Other: Nasopharyngeal Tube

• Registration Number: NCT01990599
• Lead Sponsor: Medical University of Vienna

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.

Arm && Interventions

Group	Intervention	Description
Nasopharyngeal Tube	Nasopharyngeal Tube	Every patient undergoing trigeminal thermal coagulation of the Gasserian ganglion will be ventilated by a nasopharyngeal placed ID 5mm tube during the whole neurosurgical intervention.

Primary Outcome Measures

Name	Time	Method
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 Outcome Measures

Name	Time	Method
SpO2 oxygen saturation (pulse oximeter)	Before and during the neurosurgical intervention
Hemodynamic parameters	Before and during the neurosurgical intervention
