Analgesia after bilateral myringotomy and placement of pressure equalization tubes in children: acetaminophen versus
1Department of Anesthesiology, Vanderbilt University, Nashville, Tennessee, USA.
Insights
Preoperative acetaminophen with codeine significantly reduces pain after ear tube surgery in children. This combination therapy offers superior pain relief compared to acetaminophen alone, minimizing the need for additional analgesics.
Area of Science:
- Pediatric Anesthesiology
- Pain Management
- Otolaryngology
Background:
- Bilateral myringotomy with pressure equalization (PE) tube placement is common in children.
- Postoperative pain management after PE tube insertion often requires supplemental analgesia.
- Acetaminophen and NSAIDs show limited efficacy in managing pain following this procedure.
Purpose of the Study:
- To evaluate the efficacy of preoperative acetaminophen with codeine versus acetaminophen alone for analgesia after bilateral myringotomy and PE tube placement.
- To compare pain scores and the need for supplemental analgesics between the two treatment groups.
Main Methods:
- Prospective study of 50 pediatric patients (ASA grade I or II) undergoing bilateral myringotomy and PE tube insertion.
- Randomized administration of oral midazolam premedication mixed with either acetaminophen (15 mg/kg) or acetaminophen (10 mg/kg) and codeine (1 mg/kg).
- Postoperative pain assessed using an objective pain scale at four intervals; anesthesia with halothane, nitrous oxide, and oxygen.
Main Results:
- Patients receiving acetaminophen with codeine demonstrated significantly lower pain scores at all assessment points compared to those receiving acetaminophen alone.
- None of the patients in the acetaminophen with codeine group required supplemental analgesics, versus 12 of 25 in the acetaminophen group.
- No adverse effects were observed in either treatment group.
Conclusions:
- Preoperative administration of acetaminophen with codeine provides superior postoperative analgesia following bilateral myringotomy and PE tube placement in children.
- This combination therapy effectively reduces pain and eliminates the need for additional pain medication.
- Acetaminophen with codeine is a safe and effective option for managing pain in this pediatric surgical population.
Abstract:
Despite the brief nature of the procedure with limited tissue trauma, some form of analgesia is required in most children after bilateral myringotomy and placement of pressure equalization (PE) tubes. Previous studies have demonstrated the relative inefficacy of acetaminophen and nonsteroidal antiinflammatory drugs (NSAIDs), with 30%-55% of patients requiring supplemental postoperative analgesia. We undertook a prospective study evaluating the efficacy of the preoperative administration of oral acetaminophen (15 mg/kg) versus acetaminophen (10 mg/kg) and codeine (1 mg/kg). Fifty ASA grade I or II patients were randomized to receive oral midazolam premedication (0.7 mg/kg) mixed in either acetaminophen or acetaminophen with codeine elixir. Anesthesia was induced and maintained with halothane in nitrous oxide and oxygen. Postoperative pain was assessed at four times during the postoperative course using an objective pain scale. The two groups were similar with respect to age, weight, gender, duration of anesthesia, and duration of the surgical procedure. The patients who received acetaminophen with codeine had lower pain scores at all four points when compared with patients who received acetaminophen. None of the 25 patients who received acetaminophen with codeine required supplemental analgesics compared with 12 of 25 who received acetaminophen. No adverse effects were noted in either group. We conclude that the preoperative administration of acetaminophen with codeine provides superior analgesia after bilateral myringotomy and placement of PE tubes.
