Is There a Risk of Perioperative Stroke Due to the Retraction Used During Anterior Cervical Discectomy?

Samsun University2 enrolled

Overview

In anterior cervical disc surgery, head and neck extansion position and, surgical retraction used while reaching the anterior surface of the cervical vertebra can be affect the carotid blood flow and constituting a risk for cerebral ischaemia. In this study, we planned to investigate the relationship between head position and retraction, cerebral oxygenation and postoperative cognitive functions in patients undergoing anterior cervical disc surgery.

Conditions

Cervical Disc Disease Cervical Stenosis Cervical Disc Herniation

Interventions

Near infrared spectroscopyDEVICE

The Near Infrared Spectroscopy (NIRS) is the method used for monitorize the risk of the development of cerebral ischaemia while providing information about brain tissue oxygenation.

Outcomes

Primary Outcomes

Near-infrared spectroscopy (NIRS)

Evaluate the effect of head position and surgical retraction on brain oxygenization with NIRS. Near-infrared spectroscopy (NIRS) is a brain imaging method that measures light absorbance to calculate oxy-hemoglobin (oxy-HB) and deoxy-hemoglobin (deoxy-HB), which provides an indirect measure of brain activity, particularly in the frontal cortex.

Time frame: Intraoperative

Secondary Outcomes

Mini-Mental State Examination

Evaluate the effect of head position and surgical retraction on cognitive functions with using mini-mental state examination . A Mini-Mental State Examination (MMSE) is a set of 30 questions that commonly use to check for cognitive impairment (problems with thinking, communication, understanding and memory)

Time frame: 2 hours postoperative
