Anti-reflux Control to Decrease Post Tonsillectomy Pain

Ascension Health

Status and phase: Terminated; Phase 4

Conditions: Throat Pain; Laryngopharyngeal Reflux

Treatments: Drug: Omeprazole

Study type: Interventional

Details and patient eligibility

About

The study aims to determine if treating pediatric patients (age 7-17) for four weeks with omeprazole prior to tonsillectomy will decrease post tonsillectomy pain. The hypothesis is that many patients have silent laryngopharyngeal reflux and by reducing the acid entrance into the oropharynx, patients will have less post tonsillectomy pain due to decreased acid irritation of the surgical wound (tonsil fossas).

The study will be a prospective double blind randomized study. Participants will be invited to participate in the study by giving the study information at the preoperative assessment, when the decision is made to have a tonsillectomy performed. If the patient agrees to participate in the study, a written consent and child assent will be obtained and the patient will be randomly assigned to a treatment versus control group based on the randomly assigned participant number.

The treatment group will then be given a four week course of omeprazole to be taken for the four weeks prior to tonsillectomy. The patient will be given a post tonsillectomy assessment form. The form looks at postoperative pain (using a visual analog scale 1-10) as well as oral intake at postoperative day 0,1,3,5,7,10, and 14. The form will be turned in at the postoperative visit or mailed in.

The pain level and oral intake between the two groups to will be compared to determine if antireflux control helps decrease the postoperative pain after tonsillectomy.

Full description

The study aims to determine if treating pediatric patients (age 7-18) for four weeks with omeprazole prior to tonsillectomy will decrease post tonsillectomy pain. The hypothesis is that many patients have silent laryngopharyngeal reflux and by reducing the acid entrance into the oropharynx, patients will have less post tonsillectomy pain due to decreased acid irritation of the surgical wound (tonsil fossas).

The study will be a prospective double blind randomized study. Participants will be invited to participate in the study by giving the study information at the preoperative assessment, when the decision is made to have a tonsillectomy performed. If the patient agrees to participate in the study, a written consent and child assent will be obtained and the patient will be randomly assigned to a treatment versus control group based on the randomly assigned participant number.

The treatment group will then be given a four week course of omeprazole or placebo to be taken for the four weeks prior to tonsillectomy. The investigators will be blinded to the intervention. The medication will be kept in a locked drawer at the ENT Associates office. The patient will take the medication 20 mg orally once a day for 28 days prior to the procedure with day 28 being the day before the tonsillectomy. The patient will be provided with a calender that is marked with the start date of the medication. The patient is to document any missed doses on the calender. On the day of surgery, the patient will return the remainder of the medication in an opaque bag along with the calender and this will be given back to the research pharmacist to account for the medication.

The patient will be given a post tonsillectomy assessment form. The form looks at postoperative pain (using a visual analog scale 1-10) as well as oral intake at postoperative day 0,1,3,5,7,10, and 14. The form will be turned in at the postoperative visit (2 weeks after the surgery) or mailed in.

The pain level and oral intake between the two groups to will be compared to determine if antireflux control helps decrease the postoperative pain after tonsillectomy.

Other variables collected will be patient age, gender, method of surgery, pain medication prescribed, and indication for procedure. The data will be stored in a password protected computer files and the patient will only be identified by study number.

Enrollment: 6 patients

Sex: All

Trial design

Primary purpose: Prevention

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Quadruple Blind

---

6 participants in 2 patient groups, including a placebo group

Omeprazole

Active Comparator group

Description:

Yes. Omeprazole (generic) will be used. Children \>20 kg will be given 20 mg PO daily for 4 weeks prior to tonsillectomy. This is the normal standard pediatric dosing for reflux. Omeprazole is authorized to treat reflux in children. The study focuses on laryngopharyngeal reflux that possibly contributes to post tonsillectomy pain.

Treatment:

Drug: Omeprazole

Sugar pill

Placebo Comparator group

Description:

The placebo does not look like the omeprazole, however this will not be an issue because none of the subjects will have knowledge of how the medications look.

Treatment:

Drug: Omeprazole
