  1. The study's listed conditions name Thyroid Nodule, a narrower term within Thyroid Neoplasms.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

This research is being done to better understand and test if the investigators can minimize narcotic medication for controlling pain after thyroid or parathyroid surgery. This research will be performed at Doctors Hospital At Renaissance in the investigators clinic and the perioperative area.

Participants will be randomly chosen to receive one of two options for pain management that the investigators are already using in the care of patients after surgery. One option includes a narcotic medication and one option includes a non-narcotic and a narcotic as needed.

Participants will be asked to complete a form about the level of pain and how much pain medication was needed after surgery in the hospital and while at home. Participants will not have to do any additional visits to participate in this study. The investigators will obtain the research materials at the same time as the usual care visits around the participants' surgery.

Read the detailed description

A study team member will give the participant a copy of the informed consent form to read. Participants will have a chance to ask questions about the study before agreeing to participate. If participants agree, they will be randomly chosen to receive one of two options for pain management that the investigators are already using in the care of patients (option 1: Tylenol (also known as acetaminophen) with tramadol if needed, or option 2: Tylenol #3 as needed) after surgery.

Participants will be asked to complete a form about the level of pain and how much pain medication was needed after surgery in the hospital and while at home. Participants will come to the GME General Surgery Center approximately one week after surgery for a post-operative visit so that the investigators can see how much pain medication was used and how much pain the participant had in the first few days after surgery.

Participants will not have to do any additional visits to participate in this study. The investigators will obtain the research materials at the same time as the usual care visits around the participants' surgery. It should take approximately 2 minutes each day to complete.

Lead sponsor

This is the only study on the registry with Minerva A Romero Arenas as lead sponsor.

Compared within Thyroid Nodule, this study's primary condition as ClinicalTrials.gg classifies it; the registry's first condition term is Thyroid Neoplasms. The counts are of registry records indexed under each term, refreshed daily. How we classify →

No

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Adult patients 18 years of age or older,
  2. Who are undergoing thyroid or parathyroid surgery at DHR by an Endocrine Surgery faculty member,
  3. Provide to participate in the study in English or Spanish,
  4. Patients will be included if they are discharged the same day or on postoperative day 1,
  5. Patients who undergo central lymphadenectomy will be included,
  6. Patients who undergo two operations within a 2-week period (for example a thyroid lobectomy followed by subsequent completion thyroidectomy) will only have the postoperative narcotic requirements following the initial operation included for the study analysis.
  7. Patients who have a complication, such as seroma or hematoma, requiring return to the operating room within 48 hours will be included in the study for the initial operation only.

Exclusion criteria

Exclusion Criteria:

  1. Patients who undergo lateral neck lymph node dissection will be excluded from the study due to the extent of the operation requiring a different analgesic regimen;
  2. Patients allergic to any of the study drugs will be ineligible;
  3. Patients who undergo two operations within a 2-week period (for example a thyroid lobectomy followed by subsequent completion thyroidectomy) will only have the initial operation included for the study analysis.
  4. Patients with a formal diagnosis of hepatic failure will be ineligible
  5. Patients with any diagnosis of chronic pain requiring treatment with ongoing narcotic regimen will be ineligible
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Staged narcotic analgesic regimen is non-inferior to narcotics in controlling pain

    Patient pain scores will be logged using Wong-Baker FACES pain rating scale (range 0-10) and scores will be assessed for differences between the study arms

    Time frame: Patient will report pain score up to two weeks after surgery

Secondary outcomes

  1. Is there a difference in the duration of postoperative pain requiring medication

    The number of days after surgery that participants required pain medications will be counted and assessed for difference between the study arms

    Time frame: Patient will report medication requirements up to two weeks after surgery

  2. Is there a difference in the medication requirement

    The type and quantity of pain medications used after surgery will be counted and assessed for difference between the study arms

    Time frame: Patient will report medication requirements up to two weeks after surgery

  3. Staged regimen cross over to narcotic

    The type and quantity of pain medications used after surgery will be counted and number of patients requiring cross over will be assessed

    Time frame: Patient will report medication requirements up to two weeks after surgery

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 11, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
