NCT06475365

Brief Summary

The goal of this randomized control trial is to collect sufficient preliminary data on the efficacy of sodium chloride, hereafter referred to as "saltwater" or "saline" in reducing the difficulty of swallowing following multi-level anterior cervical discectomy and fusion (ACDF) procedures. The study population will consist of generally healthy adults ages 18 - 80. The main question it aims to answer is: If the symptomatology and severity of swallowing difficulties following ACDF surgery can be reduced by gargling with warm salt water. Researchers will compare the control and interventional arms to see if the proposed intervention of gargling with warm salt water improves difficulty swallowing following surgery. Patients in the control arm will be asked to: \- Complete three (3) questionnaires at specified intervals (preoperative, postoperative day (POD) 1, 2, and 7; and at 1-month postoperatively). Patients in the experimental/interventional arm will be asked to:

  • Complete three (3) questionnaires at specified intervals (preoperative, postoperative day (POD) 1, 2, and 7; and at 1-month postoperatively).
  • Gargle with a warm saltwater solution once on POD 0, and thrice daily from POD 1 to POD 7.

Outcome Measures

Primary Outcomes (1)

  • Number of Participants with a SWAL-QOL Score of Greater Than 14

    The Swallowing-Related Quality of Life (SWAL-QOL) questionnaire is a 44-question assessment that measures the severity of oropharyngeal dysphagia (difficulty swallowing) and the impact it has on quality of life. Patients with score of greater than or equal to 14 are indicative of have some sort of difficulty with swallowing. This will be used to assess if patients in the Salt Water Gargle arm (intervention) have any relief after completing the described intervention.

    0 - 1 month

Secondary Outcomes (1)

  • Neck Disability Index (NDI) Score of 30 to 100

    0 - 1 month

Study Arms (2)

Control

NO INTERVENTION

This arm will receive no intervention. The patients in this arm will only be asked to complete the questionnaires related to the study. They will only receive the care as prescribed by their physician and care teams.

Salt Water Gargle

EXPERIMENTAL

After their surgery, this arm will receive "treatment." Patients will be asked to gargle with a warm sodium chloride (salt water) solution. Patients will gargle with 15mL (15cc) of a premade solution of salt water one time (q.d.) on postoperative day 0 (POD 0), and three times a day (t.i.d.) for the next seven (7) days following their surgery (POD 1 - POD 7). Patients will also be asked to complete a series of study-related questionnaires at specified time points.

Other: Sodium chloride gargle
