Acetaminophen plus ibuprofen versus opioids for treatment of post-tonsillectomy pain in children

Effect and safety of perioperative ibuprofen administration in pediatric tonsillectomy: A systematic review and meta-analysis

OBJECTIVES

This study aimed to evaluate the safety and efficacy of perioperative ibuprofen administration by conducting a meta-analysis of pertinent literature.

METHODS

We conducted a comprehensive review of studies sourced from PubMed, SCOPUS, Embase, Web of Science, and Cochrane databases. The studies covered the period from database inception to June 2024. A perioperative ibuprofen administration group was compared to a control group administered either saline, acetaminophen, paracetamol, or opioids. The primary outcome was post-tonsillectomy bleeding that was categorized into overall bleeding and further classified as type 1 (observed at home or evaluated in the emergency department without additional intervention), type 2 (necessitating readmission for observation), and type 3 (requiring a return to the operating room for hemorrhage control). Morbidity incidence rates for postoperative nausea and vomiting were also assessed. The secondary outcomes assessed were postoperative pain management and the frequency of analgesic drug usage. Postoperative pain management was assessed from the incidence of emergency department visits or nurses' calls for pain independent of the presence or absence of dehydration.

RESULTS

Twenty-two studies with 27,149 patients were included and reviewed for this meta-analysis. Post-tonsillectomy bleeding (OR = 0.9954, 95 % CI [0.8800; 1.1260], I2 = 0.0 %) was not significantly higher in the ibuprofen administration group compared to the control group. In subgroup analysis of post-tonsillectomy bleeding severity, ibuprofen caused clinically insignificant type 1 post-tonsillectomy bleeding that did not require intervention (OR = 1.1310 [0.7398; 1.7289]). Clinically significant bleeding requiring hospital admission (type 2) or surgical control (type 3) was not observed. Administration of ibuprofen has demonstrated efficacy in reducing the need for analgesic drugs (OR = 0.4734, 95 % CI [0.2840; 0.7893]; I2 = 19.8 %) and is associated with a significant decrease in the incidence of postoperative nausea and vomiting (OR = 0.4886, 95 % CI [0.3156; 0.7562], I2 = 34.3 %).

CONCLUSION

This study demonstrated that administration of ibuprofen for pediatric tonsillectomy did not increase the incidence of clinically significant postoperative bleeding. Ibuprofen administration decreased the incidence and severity of postoperative pain, nausea, and vomiting.

Change in Pediatric Adenotonsillectomy Postoperative Visit Patterns After Opioid Food and Drug Administration Warning

STUDY OBJECTIVE

This study aimed to determine the association between opioid prescriptions given after tonsillectomy with adenoidectomy (T + A) and pain-related return visit rates in pediatric patients. Determine association between Food and Drug Administration (FDA) black box warning against opioid use in this population and pain-related return visit rates.

METHODS

This was a single-institution retrospective cohort study of pediatric patients who underwent T + A between April 2012 and December 2015 and had return visits to the emergency department or urgent care center. Data were obtained from the hospital electronic warehouse using International Classification of Diseases-9/10 procedure codes. Odds ratios (ORs) with 95% confidence intervals (CIs) for return visits were calculated. Multivariate logistic regression analysis was used to measure association between opioid prescriptions and return visit rates as well as FDA warning and return visit rates adjusting for confounders.

RESULTS

There were 4778 patients who underwent T + A, median age, 5 years. Of these, 752 (15.7%) had return visits. Pain-related return visits were higher in patients who received opioid prescriptions (adjusted OR, 1.31; 95% CI, 1.09-1.57). After FDA warning, opioids were prescribed at a lower rate (47.9%) compared with previous (98.6%) (OR, 0.01; 95% CI, 0.008-0.02). Pain-related return visits were lower after FDA warning (OR, 0.73; 95% CI, 0.61-0.87). Steroid prescription rate increased after FDA warning (OR, 415; 95% CI, 197-874).

CONCLUSIONS

Opioid prescriptions were associated with higher pain-related return visits after T + A, whereas issuance of FDA black box warning against codeine use was associated with lower pain-related return visits. Our data suggest that the black box warning potentially had unintended benefits in pain management and health care usage.

Sustaining standardized opioid prescribing practices after pediatric tonsillectomy

INTRODUCTION

Opioid prescribing patterns after pediatric tonsillectomy are highly variable, and opioids may not improve pain control compared to over-the-counter pain relievers. We evaluated whether a standardized, opioid-sparing analgesic protocol effectively reduced opioid prescriptions without compromising patient outcomes.

METHODS

A quality improvement project was initiated in July 2019 to standardize analgesic prescribing after hospital-based tonsillectomy with/without adenoidectomy. An electronic order set provided weight-based dosing and defaulted to non-opioid prescriptions (acetaminophen and ibuprofen). Patients ages 0-6 received non-opioid analgesics alone. Patients ages 7-18 received non-opioid analgesics as first-line pain control, and providers could manually add hydrocodone-acetaminophen for breakthrough pain. Opioid prescriptions and quantities were compared for 18 months of cases pre- versus post-standardization. Postoperative returns to the system were reviewed as a balancing measure.

RESULTS

From 2018 through 2020, 1817 cases were reviewed. The frequency of opioid prescriptions decreased significantly post-standardization, from 64.9% to 33.5% of cases (P < .001). Opioid prescribing for young children steadily decreased from over 50% to 2.4%. Protocol adherence improved over time; outlier prescriptions were eliminated. Opioid quantities per prescription decreased by 16.3 doses on average (P < .001), and variance decreased significantly post-standardization (P < .001). The incidence of returns to the system did not change (P = .33), including returns for pain or decreased intake (P = .28).

CONCLUSION

An age-based and weight-based analgesic protocol reduced post-tonsillectomy opioid prescriptions without a commensurate increase in returns for postoperative complaints. Standardized protocols can facilitate sustained changes in prescribing patterns and limit potentially unnecessary pediatric opioid exposure.

Post-Tonsillectomy Ibuprofen: Is There a Dose-Dependent Bleeding Risk?

OBJECTIVES/HYPOTHESIS

Post-tonsillectomy hemorrhage (PTH) is a potentially life-threatening complication. A recent meta-analysis suggests that ibuprofen may increase the risk of PTH. The aims of this study were to 1) re-evaluate the effect of ibuprofen on PTH given additional recent evidence and 2) to evaluate a potential dose effect of ibuprofen.

STUDY DESIGN

Meta-analysis and meta-regression; single-institution retrospective review.

METHODS

We conducted a systematic review of the literature and a meta-analysis of 12 studies comparing postoperative ibuprofen analgesia to non-nonsteroidal anti-inflammatory drug (NSAID) controls. Next, we performed a meta-regression analysis to assess for an effect of dose, if any, on rates of PTH. Five studies specifying a dose of 5 mg/kg (828 patients, 1,411 controls) and 7 studies using 10 mg/kg (5,633 patients, 7,656 controls) were included. We then conducted a novel single-institution, retrospective review of data for 1,046 patients prescribed intermediate-dose 7.5 mg/kg ibuprofen.

RESULTS

Ibuprofen was not associated with an increased rate of PTH (log odds ratio [OR], 0.21; 95% confidence interval [CI] -0.15, 0.57). Meta-regression showed that ibuprofen dose (5 and 10 mg/kg) did not have a statistically significant effect on PTH (OR, 1.32; 95% CI 0.30, 5.84). Uncontrolled, aggregate rates of PTH across all studies were 2.29% (N = 828) for 5 mg/kg and 4.65% (N = 5,633) for 10 mg/kg dosing. The rate of secondary hemorrhage in patients prescribed 7.5 mg/kg ibuprofen was 3.10% (N = 1,046).

CONCLUSION

We found no statistically significant increased risk of PTH when ibuprofen is prescribed at the low or high range of commonly used clinical dosages, compared to a non-ibuprofen regimen. Further studies with less heterogeneity are needed to determine if there is a clinically relevant dose-dependent difference in PTH with ibuprofen.

Pharmacologic management of post-tonsillectomy pain in children

Tonsillectomy is a very common procedure in children, often performed on an outpatient basis. Severe postoperative pain is common, and can be prolonged. Despite a large number of available analgesic medications, often employed in combination, achieving adequate pain control remains a persistent challenge. Research suggests a tendency among caregivers to undertreat pain, and a need for detailed care instructions and education to ensure adequate pain management. Furthermore, ongoing questions regarding the safety and efficacy of the most commonly used medications have led to wide variance in practice patterns and continuous reassessment through research that yields sometimes conflicting results. This review summarizes the current state of the literature and presents a management approach which attempts to maximize pain control while minimizing potential harm with combinations of medications and modification based on patient-specific factors.

American Rhinologic Society expert practice statement: Postoperative pain management and opioid use after sinonasal surgery

The goal of this American Rhinologic Society expert practice statement (EPS) is to provide clinically applicable, evidence-based recommendations regarding pain management in sinonasal surgery. This EPS was developed following the recommended methodology and approval process as previously outlined. The topics of interest included preoperative counseling, local anesthesia, use of opioids for postoperative pain, use of nonopioid medication for postoperative pain, nonsteroidal anti-inflammatory drugs and bleeding, and use of gabapentin for pain control. Following a modified Delphi approach, 6 statements were developed, 5 of which reached consensus and 1 that did not. These statements and accompanying evidence are summarized along with an assessment of future needs.

Guidelines for Opioid Prescribing in Children and Adolescents After Surgery: An Expert Panel Opinion

IMPORTANCE

Opioids are frequently prescribed to children and adolescents after surgery. Prescription opioid misuse is associated with high-risk behavior in youth. Evidence-based guidelines for opioid prescribing practices in children are lacking.

OBJECTIVE

To assemble a multidisciplinary team of health care experts and leaders in opioid stewardship, review current literature regarding opioid use and risks unique to pediatric populations, and develop a broad framework for evidence-based opioid prescribing guidelines for children who require surgery.

EVIDENCE REVIEW

Reviews of relevant literature were performed including all English-language articles published from January 1, 1988, to February 28, 2019, found via searches of the PubMed (MEDLINE), CINAHL, Embase, and Cochrane databases. Pediatric was defined as children younger than 18 years. Animal and experimental studies, case reports, review articles, and editorials were excluded. Selected articles were graded using tools from the Oxford Centre for Evidence-based Medicine 2011 levels of evidence. The Appraisal of Guidelines for Research & Evaluation (AGREE) II instrument was applied throughout guideline creation. Consensus was determined using a modified Delphi technique.

FINDINGS

Overall, 14 574 articles were screened for inclusion, with 217 unique articles included for qualitative synthesis. Twenty guideline statements were generated from a 2-day in-person meeting and subsequently reviewed, edited, and endorsed externally by pediatric surgical specialists, the American Pediatric Surgery Association Board of Governors, the American Academy of Pediatrics Section on Surgery Executive Committee, and the American College of Surgeons Board of Regents. Review of the literature and guideline statements underscored 3 primary themes: (1) health care professionals caring for children who require surgery must recognize the risks of opioid misuse associated with prescription opioids, (2) nonopioid analgesic use should be optimized in the perioperative period, and (3) patient and family education regarding perioperative pain management and safe opioid use practices must occur both before and after surgery.

CONCLUSIONS AND RELEVANCE

These are the first opioid-prescribing guidelines to address the unique needs of children who require surgery. Health care professionals caring for children and adolescents in the perioperative period should optimize pain management and minimize risks associated with opioid use by engaging patients and families in opioid stewardship efforts.

Association of Perioperative Opioid Prescriptions With Risk of Complications After Tonsillectomy in Children

Importance

Practice guidelines recommend nonopioid medications in children after tonsillectomy, but to date, studies have not used recent national data to assess perioperative opioid prescribing patterns or the factors associated with these patterns in this population. Closing this knowledge gap may help in assessing whether such prescribing and prescription duration could be safely reduced.

Objective

To assess national perioperative opioid prescribing patterns, clinical and demographic factors associated with these patterns, and association between these patterns and complications in children after tonsillectomy compared with children not using opioids.

Design, Setting, and Participants

This cohort analysis used the 2016 to 2017 claims data from the database of a large national private insurer in the United States. Opioid-naive children aged 1 to 18 years with a claims code for tonsillectomy with or without adenoidectomy between April 1, 2016, and December 15, 2017, were identified (n = 22 567) and screened against the exclusion criteria. The final sample included 15 793 children.

Main Outcomes and Measures

The percentage of children with 1 or more perioperative fills (prescription drug claims for opioids between 7 days before to 1 day after tonsillectomy) was calculated, along with the duration of perioperative prescriptions (days supplied). Linear regression was used to identify the demographic and clinical factors associated with the duration of perioperative opioid prescriptions. Logistic regression was used to assess the association between having 1 or more perioperative fills and their duration and the risk of return visits 2 to 14 days after tonsillectomy for pain or dehydration, secondary hemorrhage, and constipation compared with children not using opioids.

Results

Among 15 793 children, the mean (SD) age was 7.8 (4.2) years, 12 807 (81.1%) were younger than 12 years, 2986 (18.9%) were between 12 and 18 years of age, and 8289 (52.6%) were female. In total, 9411 (59.6%) children had 1 or more perioperative fills, and the median (25th-75th percentile) duration was 8 (6-10) days; 6382 had no perioperative fills. The probability of having 1 or more perioperative fills and the duration of prescription varied across US census divisions. Having 1 or more perioperative fills was not associated with return visits for pain or dehydration (adjusted odds ratio [AOR], 1.13; 95% CI, 0.95-1.34) or secondary hemorrhage (AOR, 0.90; 95% CI, 0.73-1.10) compared with children not using opioids, but it was associated with increased risk of return visits for constipation (AOR, 2.02; 95% CI, 1.24-3.28). Duration was not associated with return visits for complications.

Conclusions and Relevance

These findings suggest that reducing perioperative opioid prescribing and the duration of perioperative opioid prescriptions may be possible without increasing the risk of these complications.

Reducing Readmissions Post-tonsillectomy: A Quality Improvement Study on Intravenous Hydration

INTRODUCTION

Dehydration is a potentially preventable complication post-tonsillectomy and can result in an Emergency Department visit and/or readmission. Our objectives were to identify risk factors for dehydration readmissions and develop interventions to prevent them.

METHODS

We used retrospective chart reviews to determine if increased intravenous (IV) hydration post-tonsillectomy prevented hospital readmissions for dehydration. All children aged 1-18 years who underwent tonsillectomy between July 1, 2007 and September 30, 2015 were included in this quality improvement study. Using the Pediatric Health Information System database, patients who experienced a readmission for dehydration within 72 hours of surgery were identified and validated with internal data. We analyzed the pre-implementation and post-implementation readmission rates after standardization of increased IV fluids (1.5 times maintenance). An interrupted time series analysis was used to estimate the effects of our hydration initiative.

RESULTS

Of 11,157 patients who underwent tonsillectomy during the study period, 96 (0.9%) met the criteria for readmissions for dehydration. The pre-implementation readmission rate was 1% compared to 0.2% post-implementation, a reduction of 82%.

CONCLUSIONS

The hydration initiative was associated with a significant decrease in hospital readmissions. This safe, low-cost, easy-to-implement approach to preventing dehydration post-tonsillectomy could be explored at other institutions.

Variables associated with pediatric emergency department visits for uncontrolled pain in postoperative adenotonsillectomy patients

OBJECTIVE

Returns to the emergency department (ED) for pain or dehydration after adenotonsillectomy (T&A) are frequent. Attempts to associate the specific pain regimens with these visits have been unrevealing, suggesting a need to assess for other potential factors associated with readmission.

METHODS

A review of a 2:1 cohort matched by age, gender and payer status compared post-T&A patients who did not return ED for pain or dehydration within 21 days to those who returned. Factors investigated included patient demographics, comorbidities, medication regimen and the presence of postoperative telephone encounters. Patients returning to the ED were further assessed for rates of medication adherence.

RESULTS

7493 patients underwent T&A during the period. Of these, 144 (1.9%) returned for pain/dehydration. Comparison to 285 matched patients revealed an association between ED returns and Hispanic ethnicity (p < 0.001), Spanish language (p = 0.0002), and comorbid Down syndrome and ADHD (p = 0.011 in both). The incidence of parent telephone calls to the office was associated with ED returns (58.7 in the ED cohort, 28.4% in non-ED cohort, p < 0.0001). On multivariable analysis, Hispanic ethnicity and phone calls were associated with ED returns (p < 0.0001 and p < 0.0001, respectively). Only 64.0% of patients returning to the ED were adherent with postoperative pain regimens.

CONCLUSIONS

While demographic factors may be associated with rate of ED returns for pain and dehydration, post-operative phone calls were most highly associated with returns. The majority of patients returning to the ED were non-adherent with recommended pain regimens, suggesting an opportunity to investigate medication adherence in all post-tonsillectomy patients.

Postoperative Bleeding Associated with Ibuprofen Use after Tonsillectomy: A Meta-analysis

Objective

To better quantify the risk of ibuprofen-associated posttonsillectomy hemorrhage (PTH).

Data Sources

PUBMED/MEDLINE, Web of Science, and Cochrane Clinical Trials Database.

Review Method

Literature searches were performed for English-language publications containing the terms tonsillectomy, ibuprofen, and tonsillectomy from database inception to May 2017. Human clinical trials, prospective cohort studies, and retrospective cohort studies related to tonsillectomy, ibuprofen use, and posttonsillectomy hemorrhage among pediatric patients were selected. Electronic searches revealed 151 studies, of which 12 were deemed eligible for analysis. Studies were weighted according to level of evidence and risk of bias.

Results

Pooling of results across all studies showed a statistically significant increase in PTH among the patients taking ibuprofen (odds ratio, 1.38; 95% confidence interval, 1.11-1.72). The I 2 statistic of 20.8% demonstrates overall low study heterogeneity and good comparability of the results.

Conclusion

Our meta-analysis of available cohort studies and randomized controlled trials (RCTs) shows possible increased tendency to PTH with the use of ibuprofen. This has not been demonstrated in other studies and systematic reviews because their analyses were limited by use of multiple nonsteroidal anti-inflammatory drugs and inclusion of studies limited to the perioperative period and low sample size. However, the current analysis is limited due to inclusion of many retrospective cohort studies with unclear follow-up and no blinding. Further RCTs will be required to investigate this trend toward increased PTH.

Ibuprofen for Pain Control in Children: New Value for an Old Molecule

BACKGROUND

Acute pain is one of the major complaints reported in pediatric emergency departments and general wards. Recently, both the US Food and Drug Administration and European Medicine Agency emitted some warnings regarding the use of opioids, including codeine, in children.

OBJECTIVE

The aims of this study were summarizing the main pharmacological aspects of ibuprofen, discussing the current evidence about the use of ibuprofen in different and specific clinical settings, and providing a comparison with acetaminophen and/or codeine, according to available studies.

STUDY DESIGN AND METHODS

Studies evaluating ibuprofen for the management of acute pain in children were extracted from the PubMed and MEDLINE database within the period ranging from 1985 through 2017. After discussing safety of ibuprofen and its concomitant use with acetaminophen, the specific indications for the clinical practice were considered.

RESULTS

Ibuprofen resulted to be more effective than acetaminophen, and comparable to the combination acetaminophen-codeine, for the control of acute pain related to musculoskeletal pain. Moreover, similar results have been reported also in the management of toothache and inflammatory diseases of the oral cavity and pharynx. Ibuprofen resulted to be useful as a first approach to episodic headache. Finally, the role of ibuprofen in the management of postoperative pain and, particularly, after tonsillectomy and/or adenoidectomy has been reconsidered recently.

CONCLUSIONS

Ibuprofen resulted to be the most studied nonsteroidal anti-inflammatory drug in the management of acute pain in children; in general, it showed a good safety profile and provided evidence of effectiveness, despite some differences according to the specific clinical context.

The effect of acupuncture on postoperative pain, nausea and vomiting after pediatric tonsillectomy: a systematic review

INTRODUCTION

Tonsillectomy is one of the most commonly performed surgical procedures among children around the world and management of post tonsillectomy complications are very important.

OBJECTIVES

The aim of this study was to evaluate the effects of acupuncture on the amount of pain, nausea and vomiting after tonsillectomy in children.

METHODS

In this study, two researchers searched individually for qualified articles on the effects of acupuncture on post-tonsillectomy pain, nausea and vomiting using PubMed, Cochrane Library, Embase, Google scholar and Ovid databases by September 2018.

RESULTS

After critically appraising the searched studies, 12 studies were selected and entered into a systematic review. Among the studies, various acupuncture methods were used.

CONCLUSION

This systematic review shows that acupuncture as a complementary method can prevent and reduce the severity of complications surrounding tonsillectomy.

Association of ibuprofen use with post-tonsillectomy bleeding in older children

OBJECTIVE

Evaluate post-tonsillectomy outcomes in children discharged with ibuprofen versus those without.

METHODS

This was a retrospective review of children who underwent tonsillectomy ± adenoidectomy from 2012 to 2016 at a tertiary care children's hospital. Main outcome measures included bleed rates, ER visits, and nurse phone calls.

RESULTS

Seven hundred and seventy-three patients were included; 504 had ibuprofen at discharge (ID) and 269 did not (NID). There were significant differences in mean age, 6.7 years in the ID group years versus 8.6 for the NID group (P < 0.001). Indication for surgery was sleep apnea in 70.5% of ID patients and 44.0% of NID patients (P < 0.001). Post-tonsillectomy bleeds occurred in 8.7% in the ID group and 5.9% of the NID group (P = 0.168). Other outcome measures revealed no significant differences between the two groups. There was no significant difference in the outcome measures between patients with sleep apnea or recurrent tonsillitis. Age was important; 12.1% of children 9-18 years versus 4.8% in children 3.1-6 years (P = 0.006) had post-tonsillectomy bleeding. For children 9-18 years old, 16.7% in the ID group bled versus 7.5% in the NID group (P = 0.039). Logistical regression revealed that age contributed to post-op bleeding, and ibuprofen contributed to number of ER visits.

CONCLUSION

Ibuprofen is associated with significantly elevated post-tonsillectomy bleeding in older children, further research is needed and other analgesics should be considered.

Potential Cytochrome P450 Drug-Drug Interactions among Pediatric Patients Undergoing Tonsillectomy

OBJECTIVE

To evaluate the frequency of potential cytochrome P450 (CYP) drug-drug interactions affecting opioid metabolism among children undergoing adenotonsillectomy.

STUDY DESIGN

Case series with chart review.

SETTING

Tertiary care children's hospital.

SUBJECTS AND METHODS

A retrospective review was conducted of 1000 patients undergoing adenotonsillectomy at Children's Hospital of Wisconsin. The discharge medication reconciliation form was reviewed. Each patient's list of medications was compared with various published sources to determine whether medications causing CYP inhibition or induction were present.

RESULTS

There were 157 unique medications with systemic absorption given postoperatively to this patient cohort. Eight percent of patients were on at least 5 medications after surgery other than their posttonsillectomy medication. The 5 most commonly prescribed medications were albuterol, cetirizine, fluticasone nasal spray, montelukast, and polyethylene glycol. Per a list of known CYP inducers and inhibitors published by the US Food and Drug Administration, 30 (3%) patients were on a medication that inhibited CYP3A4; 1 patient was on a CYP3A4 inducer, prednisone; and 46 (5%) patients were on a medication that inhibited CYP2D6.

CONCLUSIONS

A small fraction of patients undergoing adenotonsillectomy are on medications that potentially alter the metabolism of opioid pain medications. Given the narrow therapeutic index of opioids and increased sensitivity to opioids among patients with obstructive sleep apnea, drug-drug interactions need to be considered as they relate to whether an opioid is appropriate and at what dose.

Effect of changing postoperative pain management on bleeding rates in tonsillectomy patients

PURPOSE

To review rates of post-tonsillectomy hemorrhage (PTH) at a quaternary medical center, including the impact of narcotic versus nonsteroidal anti-inflammatory drug (NSAID) postoperative pain management.

MATERIALS AND METHODS

A retrospective review was performed of tonsillectomies conducted at a single institution between 1/1/2013 and 1/1/2017. The rates of PTH and subsequent intervention were calculated. These were categorized into patients having surgery pre- and post-July 1, 2015, the former group receiving narcotics and the latter ibuprofen with acetaminophen.

RESULTS

Of 1351 total tonsillectomies, 3.04% had PTH requiring return to the hospital. 0.74% required no further surgical intervention, whereas 2.30% required secondary surgical control. The bleed rate prior to July 2015 was 3.15%, with 1.05% non-surgical bleeds and 2.10% requiring surgery. Post-July 2015, the bleed rate was 2.92%, with 0.44% non-surgical bleeds and 2.49% requiring surgery. There were no statistically significant differences between the two groups with respect to overall, non-surgical, and surgical hemorrhage rates (p > 0.05). Of the total bleeds, the need for secondary surgery in the narcotic group was 66.7% and 85% in the NSAID group (p = 0.18). During the study period, 36 patients with PTH had their initial tonsillectomy performed at outside institutions; 53% required surgical intervention.

CONCLUSIONS

Secondary hemorrhage remains a significant cause of morbidity in post-tonsillectomy patients, often requiring surgical intervention. This review found no increased bleeding risk associated with use of ibuprofen and acetaminophen as opposed to narcotic pain relief.

Randomized Prospective Evaluation of Intraoperative Intravenous Acetaminophen in Pediatric Adenotonsillectomy

Objective

To establish the safety and efficacy of single-dose intraoperative intravenous (IV) acetaminophen in postoperative pain management following adenotonsillectomy in addition to a standardized regimen of oral pain medication.

Study Design

Randomized, controlled prospective clinical trial.

Setting

Single academic medical center.

Subjects and Methods

Patients between the ages of 3 and 17 years scheduled for tonsillectomy or adenotonsillectomy by a single surgeon between December 2014 and November 2016 were recruited. Patients were randomly assigned to 1 of 2 groups; group 1 received a single intraoperative dose of IV acetaminophen, and group 2 did not. Induction and maintenance of anesthesia, as well as operative technique, were standardized. Nursing pain scores, pain medications administered, and recovery times were reviewed during the 24-hour postoperative period. Postoperative pain regimen included standing alternating oral acetaminophen and ibuprofen.

Results

In total, 260 patients were included in the study, and 131 (50.4%) received a single intraoperative dose of IV acetaminophen. Patients receiving IV acetaminophen were more likely to experience postoperative nausea and vomiting than patients who did not receive IV acetaminophen (1.53% vs 0.00%, P = .016). There were no significant differences noted for postoperative pain scores, requirements for breakthrough pain medications, time to discharge from the recovery room or hospital, or postoperative complications.

Conclusion

The use of a single intraoperative dose of IV acetaminophen was associated with minimal additional adverse effects. However, a single intraoperative IV dose of acetaminophen added to standard narcotic and nonnarcotic pain medication does not provide a statistically significant improvement in pain control.

Is celecoxib a useful adjunct in the treatment of post-tonsillectomy pain in the adult population? A randomised, double-blind, placebo-controlled study

OBJECTIVE

To evaluate the efficacy and safety of celecoxib for pain management in post-tonsillectomy adult patients.

DESIGN

A randomised, double-blind, placebo-controlled, phase 3 clinical trial was conducted in an adult population (aged 18-55 years), with a parallel group design using an allocation ratio of 1:1.

METHODS

Eighty patients underwent elective tonsillectomy or adenotonsillectomy, operated on by one surgeon. They were discharged home with randomly assigned celecoxib or placebo, together with regular post-tonsillectomy medications (paracetamol and Endone). Pain scores were measured from post-operative days 1 to 10. All patients were assessed on post-operative days 5, 12 and 28.

RESULTS

There were no statistically significant differences in the daily or overall pain scores, the total intake of Endone, or the time taken to achieve freedom from pain after tonsillectomy between the study arms (n = 40 each arm). The celecoxib-treated group experienced significantly more vomiting (celecoxib vs placebo p < 0.001 (Mann-Whitney test), confidence interval = 0.57 to 0.76).

CONCLUSION

Celecoxib usage was associated with significantly more vomiting and did not reduce narcotic analgesia requirement post-tonsillectomy.

Assessment and management of pain in pediatric otolaryngology

INTRODUCTION

Pain is a disease by itself and it's a public health concern of major implication in children, not just because of the emotional component of the child and his family, but also due to the potential morbidity and mortality involving it. A proper assessment of pain it's a challenge in the pediatric population, due to their lack of understanding and verbalization of hurt. Additionally, a satisfactory treatment of pediatric pain can be arduous due to a lack of clinical knowledge, insufficient pediatric research, and the fear to opioid side effects and addiction.

OBJECTIVES

The aim of this review is to address the current definitions of pain, its physiological mechanisms and the consequences of its inadequate management, as well as, to guide the clinicians in the assessment and management of pain in the pediatric population at otolaryngology services.

METHODOLOGY

Narrative review by selective MeSH search terms: Children, Pediatrics, Otolaryngology, Pain measurement, Pain Management, Analgesics and Analgesia, from databases: MEDLINE/PubMed, Cochrane, ISI, Current Contents, Scielo and LILACS, between January 2000 and May 2016.

RESULTS

129 articles were reviewed according to the requirements of the objectives. Pain measurement is a challenge in children as there are no physical signs that constitute an absolute or specific indicator of pain, and its diagnosis must rely on physiological, behavioral and self-report methods. Regarding treatment, a suitable alternative are the non-pharmacological cognitive/behavioral therapies helped by pharmacological therapies tailored to the severity of pain and the child's age. We provide evidence-based recommendations on pain treatment, including non-opioid analgesics, opioid analgesics and adjuvant medicines to improve the management of pain in children in otolaryngology services.

CONCLUSIONS

We present a global review about assessment and management of pain in pediatric otolaryngology, which leads to future specific reviews on each topic. Research gaps on pain assessment and pharmacological interventions in neonates, infants and children are very wide and it should be promoted ethical and safe research on pain control in this population.

Primary Caregiver Perception of Pain Control following Pediatric Adenotonsillectomy

Objectives

To (1) review pain medications prescribed following pediatric adenotonsillectomy (T&A), (2) identify pain medications reported to be helpful, and (3) compare parent-reported outcomes among various combinations of pain medications.

Study Design

Case series with planned data collection.

Setting

Multihospital network.

Subjects and Methods

The primary caregivers of children aged 1 to 18 years who underwent isolated T&A from June to December 2014 were contacted 14 to 21 days after surgery. Data collected included pain medications prescribed, medications most helpful in controlling pain, and duration that pain medication was required. Parents rated their children’s pain on postoperative days 2, 3, 7, and 14 and reported the time to resumption of normal diet/activity, as well as any hospital return visits.

Results

The study cohort included 672 subjects of 1444 potential participants (46% response rate). The mean age of the patients was 7.9 ± 3.6 years. Narcotics were prescribed in 71.9%, and 70.4% were told to use ibuprofen. Children who took ibuprofen alone were significantly younger ( P < .001). Pain was significantly less on postoperative days 2 and 3 in the ibuprofen-only group as compared with the groups taking narcotics only ( P < .001) and ibuprofen with narcotics ( P = .002). Those taking ibuprofen alone returned to normal activity ( P < .001) and diet ( P = .026) sooner than those taking ibuprofen with narcotics. No difference was seen in pain control on subgroup analysis comparing oxycodone and hydrocodone.

Conclusions

For pediatric T&A, significant variation exists in the management of postoperative pain. Parents of children given ibuprofen reported less pain than those given narcotics with and without ibuprofen. Further studies are needed to identify the optimal pain regimen for children after T&A.

Codeine: Time to Say "No"

Codeine has been prescribed to pediatric patients for many decades as both an analgesic and an antitussive agent. Codeine is a prodrug with little inherent pharmacologic activity and must be metabolized in the liver into morphine, which is responsible for codeine's analgesic effects. However, there is substantial genetic variability in the activity of the responsible hepatic enzyme, CYP2D6, and, as a consequence, individual patient response to codeine varies from no effect to high sensitivity. Drug surveillance has documented the occurrence of unanticipated respiratory depression and death after receiving codeine in children, many of whom have been shown to be ultrarapid metabolizers. Patients with documented or suspected obstructive sleep apnea appear to be at particular risk because of opioid sensitivity, compounding the danger among rapid metabolizers in this group. Recently, various organizations and regulatory bodies, including the World Health Organization, the US Food and Drug Administration, and the European Medicines Agency, have promulgated stern warnings regarding the occurrence of adverse effects of codeine in children. These and other groups have or are considering a declaration of a contraindication for the use of codeine for children as either an analgesic or an antitussive. Additional clinical research must extend the understanding of the risks and benefits of both opioid and nonopioid alternatives for orally administered, effective agents for acute and chronic pain.

Analgesia for acute gingivostomatitis: a national survey of pediatric emergency physicians

Objectives

Gingivostomatitis is a common, painful pediatric presentation, and yet, few studies are available to guide management. We aimed to describe pediatric emergency physicians’ current practice patterns, with respect to analgesic use in children with acute gingivostomatitis, in order to inform future studies.

Methods

A national survey was conducted at all 15 national academic pediatric centres.

Electronic surveys were distributed to pediatric emergency physicians using a modified Dillman protocol; non-respondents received paper surveys via post. Data were collected regarding demographic characteristics, clinical behaviour, factors that may influence practice, and future directions.

Results

Response rate was 74% (150/202). Most physicians (72%) preferred the combination of acetaminophen and ibuprofen to either agent alone (ibuprofen 19%, acetaminophen 7%). The preferred second-line analgesics were oral morphine (48%, 72/150) and compounded topical formulas (42%, 64/150). The most commonly cited compounded agent was Benadryl plus Maalox (23%, 35/150). Clinical experience with a medication had the greatest influence on practice pattern, with 52% (78/149) strongly agreeing. The most commonly cited barrier to adequate analgesia was difficulty in the administration of topical or oral medication to children.

Conclusions

As with many other painful conditions, the combination of acetaminophen and ibuprofen was preferred, followed by either agent alone. Oral morphine and topical compounded agents were also frequently prescribed. Regardless of patient age, physicians preferred oral morphine as a second-line agent to treat pain from severe gingivostomatitis. Future research will focus on determining which analgesic and route (oral or topical) is the most effective and best-tolerated choice.

Celecoxib Versus Placebo in Tonsillectomy

Objectives:

Celecoxib is a cyclooxygenase-2-specific inhibitor indicated to treat acute pain and pain secondary to osteoarthritis and rheumatoid arthritis. Surgical models of acute pain have demonstrated superior pain relief to placebo. The objective of this study was to test the safety and efficacy of celecoxib for pain relief after tonsillectomy compared to placebo.

Methods:

Adult subjects were randomized to 200 mg celecoxib versus placebo with a loading dose the night before surgery then twice daily for 10 days. Subjects were instructed to supplement the study drug with hydrocodone/acetaminophen liquid or acetaminophen for pain as needed. Subjects completed a daily diary regarding their pain, nausea, vomiting, diet, and activity.

Results:

Seventeen subjects enrolled. Intraoperative blood loss was similar between groups, and no subject had postoperative bleeding. Three patients returned to the emergency department for treatment, and 2 patients could not complete the diaries, all in the placebo group. Subjects in the placebo group required statistically significant ( P < .05) higher doses of narcotic and acetaminophen to control pain. Pain and diet rating scores were slightly better in the celecoxib group compared to placebo.

Conclusions:

In this small cohort, celecoxib reduced postoperative narcotic and acetaminophen requirements compared to placebo without complications.

A Randomized Controlled Trial of Oral Versus Intravenous Administration of a Nonnarcotic Analgesia Protocol Following Pediatric Craniosynostosis Corrections on Nausea and Vomiting Rates

BACKGROUND

The authors' center uses a nonnarcotic postoperative regimen following craniosynostosis corrections. Despite opioid avoidance, the authors noted that some children still experienced nausea and vomiting following the oral administration of either acetaminophen or ibuprofen. This study sought to evaluate whether intravenous administration of these medications might reduce nausea and vomiting rates.

METHODS

A total of 50 children undergoing craniosynostosis corrections were prospectively randomized to a control group given only oral ibuprofen (10 mg/kg) and acetaminophen (15 mg/kg), or a treatment group given only intravenous ketorolac (0.5 mg/kg) and acetaminophen (15 mg/kg). All patients were assessed for postoperative nausea and vomiting by a blinded research nurse.

RESULTS

Twenty-eight patients randomized to the oral control group, and 22 to the intravenous treatment group. No statistically significant differences were identified between groups, including: age, weight, sex, before history of severe postoperative nausea and vomiting, or procedure. With similar anesthesia times there was significantly more vomiting episodes in the oral group (71% versus 41%). Using a multivariate logistic regression, controlling for age, weight and procedure, the odds ratio for vomiting in the oral control versus intravenous experimental groups was 3.61 (95% CI 1.11-1.76; P = 0.033), and for postoperative nausea was 14.0 (95% CI 1.40-71.69, P = 0.010).

CONCLUSIONS

The authors found a significant reduction in nausea and vomiting among children randomized to receive intravenous medications. In addition, the intravenous delivery of medications has the theoretical advantage of insuring an effective full dose delivery. Based on these findings, our standard process is to preferentially manage all children following craniosynostosis corrections with intravenous nonnarcotics.

Outcomes of an Alternating Ibuprofen and Acetaminophen Regimen for Pain Relief After Tonsillectomy in Children

Objectives:

To determine the outcomes of alternating doses of ibuprofen and acetaminophen in the treatment of post-tonsillectomy pain in children and to identify characteristics of children who had inadequate pain control.

Methods:

The medical records of children who received alternating doses of ibuprofen and acetaminophen for post-tonsillectomy pain between August 2012 and November 2013 at a tertiary care children’s hospital were reviewed. Incidences of postoperative bleeding and unresolved pain were determined.

Results:

A total of 583 patients (304 males, 279 females, age range =1-18 years) had received alternating doses of ibuprofen and acetaminophen after tonsillectomy and adenoidectomy. Of the 583 patients, 56 (9.6%) reported inadequate pain control. Age, sex, obesity, presence of comorbid conditions, indications for surgery, and concurrent surgical procedures were not different between children who had adequate analgesia and children who had unresolved pain. Twenty-four patients (4.1%) had postoperative bleeding. Nine patients (1.5%) required surgical intervention for bleeding.

Conclusions:

Alternating doses of ibuprofen and acetaminophen provided an effective treatment for post-tonsillectomy pain in the majority of children and did not increase rate of bleeding. Means of improving response rate to alternating doses of ibuprofen and acetaminophen merit further investigation.

Swedish guidelines for the treatment of pain in tonsil surgery in pediatric patients up to 18 years

BACKGROUND

Surgery of the tonsils often causes severe pain lasting for many days as been shown by data from the National Tonsil Surgery Register in Sweden. Tonsillotomy is associated with fewer readmissions due to bleeding, number of days requiring analgesics and health care contacts due to pain compared to tonsillectomy. The register data demonstrate the necessity of better-evidenced based pain treatment guidelines for tonsil-surgery.

OBJECTIVES

To develop evidenced based pain treatment guidelines for tonsil-surgery in Sweden.

METHODS

The evidence based guidelines were designed by an updated literature review and from the clinical expertise in the pediatric pain field, which thereafter were reviewed by ENT-doctors and anesthetists from each ENT-clinic in Sweden.

RESULTS

A multimodal pain treatment approach is advocated, including premedication and administration during anesthesia, with paracetamol (acetaminophen), clonidine and betamethasone. If not given as a premedication the combination can be administered intravenously in the initial phase of anesthesia. At the end of surgery, if no bleeding problems, cox-inhibitors can be given. After discharge from hospital, the recommendations for pain relief are paracetamol combined with cox-inhibitors (ibuprofen, diclofenac) and if needed oral clonidine in favor of opioids. When pain intensity decreases, discontinue the analgesic treatment in the following order: opioid, clonidine, paracetamol and at last ibuprofen. The need for analgesic treatment after tonsillectomy is usually 5-8 days, after tonsillotomy only 3-5 days. Parents are recommended to contact the hospital if the child has difficulties in drinking or eating adequately and/or suffers from pain despite taking the recommended medication regularly.

CONCLUSIONS

Swedish guidelines for tonsil-surgery provide practical evidence-based pain treatment recommendations.
