What postoperative instructions should be given after tonsillectomy and adenoidectomy?

Post-Tonsillectomy and Adenoidectomy Instructions

Prescribe ibuprofen, acetaminophen, or both for pain control on a scheduled basis, and absolutely avoid codeine in children under 12 years old. 1

Pain Management (Most Critical Component)

Medication Regimen

• Administer ibuprofen and/or acetaminophen around-the-clock for the first several days, not just as needed 1
• Give pain medication on a regular schedule, including waking the child at night during the first few postoperative days 1
• Alternating ibuprofen and acetaminophen is recommended for optimal pain control 1
• If oral intake is refused, rectal acetaminophen is an acceptable alternative 1

Critical Safety Warning: Never prescribe or administer codeine or any codeine-containing medication to children under 12 years old—this carries an FDA black box warning due to risk of fatal respiratory depression, particularly in ultra-rapid metabolizers and children with OSA 1

Pain Assessment

• Caregivers should assess pain every 4 hours using age-appropriate validated scales 1:
  • Wong-Baker FACES scale for children ≥3 years
  • FLACC scale for children 2 months to 7 years
  • Numeric scale (0-10) for older children
• Children may not spontaneously report pain, so proactive assessment is essential 1

Expected Pain Course

• Pain typically lasts 7-10 days but can persist up to 2 weeks 1
• Pain may be worse in the morning (this is normal) 1
• Throat pain, ear pain, and neck pain are all expected 1

Non-Pharmacologic Pain Management

Supplement (but do not replace) medications with 1:

• Distraction techniques (favorite toys, video games, television)
• Cold or hot packs applied to neck/ears
• Interactive activities (bubbles, art projects, coloring, reading)

Diet and Hydration

No dietary restrictions are necessary—children can eat a normal diet as tolerated 1

Specific Instructions

• Hydration is critical and associated with less pain 1
• Offer frequent small amounts of fluids via bottle, sippy cup, or glass 1
• Encourage chewing and eating, including:
  • Fruit snacks
  • Popsicles
  • Pudding
  • Yogurt
  • Ice cream
  • Regular foods as tolerated 1

Note: The traditional "soft diet only" restriction is not evidence-based. Research shows no difference in complications between restricted and unrestricted diets, and some evidence suggests unrestricted diets may improve recovery 2, 3

Activity Level

No strict activity restrictions are necessary—children may return to normal activities as tolerated 2, 3

• Some evidence suggests activity restrictions may actually increase bleeding risk 2
• Allow children to self-regulate their activity level
• Avoid only extremely strenuous activities for the first week

Monitoring for Complications

Bleeding (Primary Concern)

Caregivers must understand bleeding risk and when to seek care:

• Primary bleeding occurs within 24 hours of surgery 1
• Secondary bleeding occurs after 24 hours (typically days 5-10) 1
• Any bleeding beyond minor blood-tinged saliva requires immediate medical evaluation
• Severe bleeding is a medical emergency requiring emergency department evaluation

When to Contact the Surgeon

• Inability to adequately control pain with prescribed medications 1
• Any significant bleeding
• Persistent fever
• Dehydration (decreased urination, dry mouth, lethargy)
• Difficulty breathing

Special Populations Requiring Inpatient Monitoring

Arrange overnight hospital observation for 1:

• Children <3 years old
• Children with severe OSA (AHI ≥10 events/hour or oxygen saturation nadir <80%)

Follow-Up

• Document presence or absence of bleeding at follow-up 1
• Counsel families that obstructive sleep-disordered breathing may persist or recur after surgery and require further management 1

Common Pitfalls to Avoid

1. Underdosing pain medication due to parental fear of side effects—studies show only 17% of parents give the recommended 4 doses on postoperative day 1 1
2. Prescribing codeine despite clear contraindication and FDA black box warning 1
3. Unnecessarily restricting diet, which may prolong recovery and increase parental anxiety 2, 3
4. Failing to emphasize hydration, which is directly associated with reduced pain 1
5. Not providing specific pain assessment tools to caregivers, leading to undertreatment 1

The 2019 AAO-HNS guidelines represent a significant shift toward more aggressive pain management with safer medications and away from unnecessary dietary restrictions, based on systematic reviews showing ibuprofen does not increase bleeding risk despite persistent clinical concerns 1, 4.
