Post-tonsillectomy Pain Control in Adults

Hypotheses

• There is an optimal pain control regimen for post-tonsillectomy pain control in adults
• Post-tonsillectomy pain levels in adults peak around postoperative day number seven
• Post-tonsillectomy adults return very slowly to normal (pre-surgery) oral intake and diet

Purpose

• To assess daily post-tonsillectomy pain level in adults for the two weeks after surgery
• To determine if there is an optimal post-tonsillectomy pain control regimen in adults for the two weeks after surgery
• To determine oral intake levels in post-tonsillectomy adults for the two weeks after surgery
• To determine daily amounts of nausea/vomiting in post-tonsillectomy adults for the two weeks after surgery
• To determine the change in weight in the two to three weeks after surgery

Study Background Tonsillectomy (with or without adenoidectomy) is a very common procedure in children and adults. The most common indications for tonsillectomies include chronic tonsillitis and/or obstructive sleep apnea. While many studies have examined the optimal postoperative pain control regimen in children, the optimal pain control regimen in adults remains poorly studied and understood.

Literature regarding post-tonsillectomy pain in adults has primarily focused on the specific tonsillectomy surgical technique (there are many) rather than the exact medications used for pain control. Interestingly, some of these aforementioned studies did not include the name, type or quantity of pain medications given to their patients when the primary study endpoint was pain. Additional studies have examined the role of steroids, antibiotics, and/or pain medications given by Anesthesia while a patient is anesthetized and undergoing tonsillectomy to determine if this can reduce postoperative pain. IV steroids given perioperatively to adults undergoing tonsillectomy have less pain, nausea, and vomiting in the first few days after tonsillectomy. IV steroids are now routinely given before tonsillectomy by most practicing Otolaryngologists, including our senior authors.

There are a limited number of studies looking at actual postoperative pain control regimens in adults. Most of these studies are limited in that they only looked at the first 24 hours following surgery rather than trending pain levels for the first week or two after surgery. Additional studies are limited because they are observational or prospective without comparative pain regimen groups (i.e. they gave all patients the same medications asked them their daily pain levels).

Furthermore, a majority of studies involving postoperative pain control used a "cold steel" technique tonsillectomy, which is uncommonly practiced in the United States by Otolaryngologists, who prefer the use of electrocautery devices for tonsillectomy. It is well known and accepted that cautery causes more postoperative pain due to thermal tissue injury, however it allows for a straightforward surgery with better intraoperative control of bleeding. Furthermore, randomized prospective studies for postoperative pain control following cautery tonsillectomy are lacking in the literature.

It is well known that the expected recovery period for adults is 2-4 weeks, during which they cannot work or do any strenuous activity. We would argue that the first 24 hours after tonsillectomy is actually better tolerated by adults because they have received high potency narcotics (usually through their IV) during and right after surgery. Therefore a more meaningful time period to study would be postoperative day number 1 - 14, when the patient is at home and the pain is most severe (most patients state that their pain peaks around postoperative number 5-7). Pain control is incredibly important issue in the post-tonsillectomy patient. If they have too much pain, they will not drink or eat enough to stay hydrated and nourished. This can lead to electrolyte abnormalities and dehydration requiring visits to the Emergency Department with or without admission to the hospital.

The purpose of this study is to evaluate post-tonsillectomy pain control in adults using three randomized medication regimens. All patients would undergo the same surgical technique to avoid confounding variables. Surgeries would be performed by Otolaryngology - Head and Neck Surgery Residents under the direct supervision of Otolaryngology staff attending surgeons. All of the proposed pain regimens are commonly accepted regimens used by practicing Otolaryngologists for adults.

Patients would be asked to complete a questionnaire that numerically evaluates their daily: pain level, amount of oral intake, amount of nausea/vomiting, and amount of pain medications used. They would asked to mail in their results or return the clinic. Additional information would be collected from the patients and/or their medical records including visits to the emergency department, readmissions to the hospital, and postoperative complications including post-tonsillectomy bleeding. Data would be compiled and analyzed to determine the typical postoperative pain levels, daily oral intake level, and to compare the different pain regimens to determine if one is superior.

It is important to note that there are accepted risks of general anesthesia and undergoing tonsillectomy with or without adenoidectomy. Participation in this study would not change any of the accepted risk of undergoing the surgical procedure. The risks commonly discussed with patients before tonsillectomy with or without adenoidectomy include failure to resolve chronic throat infections, failure to resolve obstructive sleep apnea, voice changes after surgery, damage to lips/teeth/tongue, taste changes, dehydration, need to return to the emergency department, need for admission to the hospital, and 3-5% risk of post-tonsillectomy bleeding that may result in need for additional surgical procedures and/or blood transfusions.
