NCT06662422

Brief Summary

In this blinded prospective randomized control trial the researchers will investigate the impact of cutaneous vagal nerve stimulation on surgical conditions in patients undergoing functional and ascorbic sinus surgery (FESS). The device is an externally placed vagal nerve stimulator. The device will be applied to participants after consent and induction of anesthesia. The study team will open the randomization envelope and if the participant is assigned to stimulation the device will be turned on. In the case that the participant is assigned to the control arm, the device will be set to sham. The device will remain on for 30 minutes and removed before entering the OR. Device will be reinserted in the recovery room for another 30 minutes.

Outcome Measures

Primary Outcomes (1)

  • Boezaart Score

    Perioperative bleeding by Boezaart Score. Full scale is graded from Grade of 0 (clear surgical field) to 5 (severe bleeding). Higher score indicates more severe bleeding.

    every 15 minutes during surgical procedure

Secondary Outcomes (3)

  • Post-operative nausea score

    during PACU stay, average PACU stay is 3 hours

  • Post-operative vomiting score

    during PACU stay, average PACU stay is 3 hours

  • Visual Analog Scale (VAS) for Post-operative pain score

    30 minutes after procedure

Study Arms (2)

Electrostimulation

EXPERIMENTAL

Device will be turned on to send electrostimulation.

Device: Spark Biomedical Sparrow Ascent Transcutaneous Auricular Neurostimulation (tAN) System

Sham - no electrostimulation

SHAM COMPARATOR

Device will be toggled to Sham so no electrostimulation will be given.

Device: Spark Biomedical Sparrow Ascent Transcutaneous Auricular Neurostimulation (tAN) System

Interventions

The Spark Biomedical Sparrow Ascent Transcutaneous Auricular Neurostimulation (tAN) System is a single-use electrode placed on and around the ear which provides transcutaneous auricular neurostimulation (tAN), which targets the auricular branch of the vagus nerve (ABVN) and the auriculotemporal nerve (ATN).

ElectrostimulationSham - no electrostimulation
