A descriptive analysis of pediatric post-tonsillectomy pain and recovery outcomes over a 10-day recovery period from 2 randomized, controlled trials

Keep Calm: Does parental preoperative anxiety affect post-tonsillectomy pain scores in children?

PURPOSE

To understand if high parental anxiety leads to increased post-tonsillectomy pain in children.

METHODS

Prospective study including parents of children aged 3-10 years old submitted to tonsillectomy with or without adenoidectomy. To evaluate anxiety, parents were asked to fill the State-Trait Anxiety Inventory form-Y, with postoperative pain being evaluated with the Wong-Baker FACES pain scale at postoperative days 1, 3 and 7. Parents were also asked to register the number of days during which children took analgesic and the number of analgesic intakes needed.

RESULTS

41 parents were enrolled, of which 95.1% (n = 39) were female with a mean age of 35.64 years (SD 5.751), with 41 children also being enrolled, of which 85.4% of children (n = 35) underwent tonsillectomy and adenoidectomy. 43.9% (n = 18) of parents presented State anxiety scores above the cut-off level and 53.7% (n = 22) above the Trait anxiety scores above the cut-off. Children of parents with high State anxiety presented statistically higher pain scores in both the third (p = 0.035) and the seventh postoperative days (p = 0.006), with significantly longer use of analgesic medication (p = 0.043) being found, as well as a statistically higher number of analgesic intakes (p = 0.045) (Table 4).

CONCLUSION

The present study establishes an association between preoperative parental anxiety, postoperative pain scores and the need for longer analgesic use in children undergoing tonsillectomy. This reinforces the importance of reducing parental anxiety and opens the door for further strategies to better post-tonsillectomy outcomes.

Suprazygomatic Maxillary Nerve Blocks and Opioid Requirements in Pediatric Adenotonsillectomy: A Randomized Clinical Trial

Importance

Pain management following pediatric adenotonsillectomies is opioid-inclusive, leading to potential complications.

Objective

To investigate the use of suprazygomatic maxillary nerve (SZMN) blocks to reduce pain and opioid use after pediatric intracapsular adenotonsillectomy and to measure recovery duration and incidence of complications.

Design, Setting, and Participants

This was a randomized, blinded, prospective single-center tertiary pediatric hospital that included 60 pediatric patients (2-14 years old) scheduled for intracapsular adenotonsillectomy from November 2021 to March 2023. Patients were excluded for having combined surgical procedures, developmental delay, coagulopathy, chronic pain history, known or predicted difficult airway, or unrepaired congenital heart disease. Participants were randomized to receive bilateral SZMN blocks (block group) or not (control group).

Intervention

SZMN block administered bilaterally under general anesthesia for intracapsular adenotonsillectomy.

Primary Outcomes and Measures

Opioid consumption, FLACC (Face, Legs, Activity, Cry, Consolability) scores, and rates of opioid-free postanesthesia care unit (PACU) stay. Secondary outcomes were recovery duration and incidence of adverse effects, ie, nausea, vomiting, block site bleeding, and emergency delirium.

Results

The study population included 53 pediatric patients (mean [SD] age, 6.5 [3.6] years; 29 [55%] females; 24 [45%] males); 26 were randomly assigned to the SZMN block group and 27 to the control group. The mean (SD) opioid morphine equivalent consumption during PACU stay was 0.15 (0.14) mg/kg for the 27 patients in the control group compared with 0.07 (0.11) mg/kg for the 26 patients in the block group (mean difference, 0.08; 95% CI, 0.01-0.15; Cohen d, 0.64). The block group had a higher incidence of opioid-free PACU stays (n = 7 patients; 58%) compared with the control group (n = 15 patients; 26%) (mean difference, 32%; 95% CI, 5%-53%). Patients in the block group experienced lower FLACC scores (0.7 vs 1.6; mean difference, 0.9; 95% CI, 0.2-1.6; Cohen d, 0.7). The overall occurrence of adverse events was similar in the 2 groups, with no reported nerve block-related complications.

Conclusions and Relevance

The results of the randomized clinical trial indicate that SZMN blocks are a useful adjunct tool for managing postoperative pain in pediatric intracapsular adenotonsillectomy. Use of these blocks during adenotonsillectomy provided clinically meaningful reductions of postoperative opioid consumption with a low risk of complications.

Post-Tonsillectomy Bleeding and Analgesic Use Before and After the FDA Boxed Warning Against Codeine

OBJECTIVE

The aim of this study was to investigate the trends in post-tonsillectomy analgesic utility and incidence of post-tonsillectomy hemorrhage before and after the 2013 FDA Boxed Warning against codeine use after pediatric tonsillectomy.

METHODS

A retrospective study was conducted using TriNetX. A search for patients up to 18 years from 2008 to 2022 within the US Collaborative Network identified 15,648,542 subjects. CPT and ICD-10 codes were used to identify children who experienced post-tonsillectomy hemorrhage within 14 days of a tonsillectomy. Analgesics given within 14 days of tonsillectomy were tabulated annually from 2008 to 2022, including codeine, ibuprofen, acetaminophen, oxycodone, ketorolac, and hydrocodone. Bleeding percentage and analgesic utility were grouped into events before and after 2013.

RESULTS

Mean age at tonsillectomy was 5.6 years (SD = 3.0). Before 2013, the median percentage of children who experienced postoperative bleeding was 1.8% with 0.73% returning to the OR for bleeding control. After 2013, the median percentage of children who experienced postoperative bleeding was 2.4% (p = 0.029), and 0.99% returned to the OR (p = 0.008). Use of post-tonsillectomy codeine fell from 10.4% to 0.5% (p = 0.003) whereas ibuprofen rose from 2.0% to 63.9% (p = <0.001), acetaminophen from 42.8% to 77.2% (p = <0.001), ketorolac from 1.2% to 9.2% (p = <0.001), and oxycodone from 2.0% to 30.9% (p = <0.001). No change was detected in use of hydrocodone.

CONCLUSION

Analgesics used post-tonsillectomy in children have changed since the FDA Boxed Warning against codeine. There has been a small but statistically significant increase in post-tonsillectomy bleeding.

New postoperative pain instrument for toddlers-Secondary analysis of prospectively collected assessments after tonsil surgery

BACKGROUND

The Children's and Infant's Postoperative Pain Scale (CHIPPS) and the German version of the Parent's Postoperative Pain Measure (PPPM-D) are used to assess postoperative pain intensity in preschool children. However, they have shown low concordance in previous prospective studies on quality improvement.

AIMS

Our secondary analysis aimed to estimate the association strength between the pain score items and indication for rescue medication defined as CHIPPS ≥4 and/or PPPD-D ≥ 6. Thus, we intended to create a further developed pain instrument with fewer variables for easier routine use.

METHODS

We analyzed 1067 pain intensity assessments of hospitalized children for the development of our novel tool in two steps using modern statistical and machine-learning methods: (1) Boruta variable selection to analyze the association strength between CHIPPS score, PPPM-D items, age, weight, and elapsed time after surgery, including their interactions and pattern stability, and the binary outcome (analgesics required yes/no). (2) Symbolic regression to generate a short formula with the least number of variables and highest accuracy for rescue medication indication.

RESULTS

Additional analgesics were required in 19.96% of pain intensity assessments, whereby the PPPM-D showed higher variance than CHIPPS. Boruta identified PPPM-D score, CHIPPS score, 9 of the 15 PPPM-D variables, and time of assessment as associated with the indication for RM. Symbolic regression revealed that additional analgesics are required if CHIPPS is ≥4 OR PPPM-D item "less energy than usual" AND one of the items "more easily cry" or "more groan/moan" are answered with "yes." These PPPM-D items were not redundant and showed nonlinear course over time. The cross-validated accuracy for this assessment tool was 94.94%.

CONCLUSIONS

The new instrument is easy to use and may improve postoperative pain intensity assessment in children. However, it requires prospective validation in a new cohort.

Pain management after tonsil surgery in children and adults-A national survey related to pain outcome measures from the Swedish Quality Register for tonsil surgery

OBJECTIVE

The primary aim of this study was to describe the current practice regarding pain management in relation to tonsil surgery among Ear Nose and Throat (ENT) clinics in Sweden. The secondary aim was to determine the impact of the provider's regime of rescue analgesics on the pain related Patient Reported Outcome Measures (pain-PROMs) from the Swedish Quality Register for Tonsil Surgery (SQTS).

MATERIALS & METHODS

A descriptive cross-sectional study originating from a validated web-based questionnaire. The survey enrolled one respondent from each ENT clinic (47/48 participated) nationally. Pain-PROMs from the SQTS, recorded from October 2019 to October 2022, were included (8163 tonsil surgeries).

RESULTS

Paracetamol was used by all enrolled ENT clinics as preemptive analgesia. The addition of COX inhibitors was used in 40% of the clinics. Betamethasone was usually administered, to prevent pain and nausea (92%). All clinics gave postdischarge instructions on multimodal analgesia with COX inhibitors and paracetamol. Rescue analgesics were prescribed after tonsillectomy for 77% of adults, 62% of older children, 43% of young children and less often after tonsillotomy. The most frequently prescribed rescue analgesic was clonidine in children (55%) and oxycodone in adults (72%). A high proportion of patients reported contact with health care services due to postoperative pain (pain-PROMs/ SQTS). Tonsillectomy procedures were associated with the highest rates of contacts (children/adolescents 13-15%; adults 26%), while tonsillotomy were associated with lower rates, (5-7% of children/adolescents). There was no significant difference in the frequency of health care contacts due to pain regarding whether clinics routinely prescribed rescue analgesics or not after tonsillectomy.

CONCLUSION

The Swedish analgesic regimen after tonsil surgery is good overall. Nevertheless, there is a need for increased awareness and knowledge to achieve optimal patient recovery. Pain-PROM data demonstrate the call for improvement in pain management after tonsil surgery.

The post-operative tonsillectomy (POPT) study: A multi-centre prospective paediatric cohort study

OBJECTIVES

Tonsillectomy is the most common operation performed by otolaryngologists in the UK, despite this we have a poor understanding of the post-operative recovery. We aimed to investigate post-operative bleeding and pain following paediatric tonsillectomy using a patient diary.

DESIGN

Prospective observational cohort study.

SETTING

Multi-centre study involving 12 secondary and tertiary otolaryngology units across the North of England. Patients were recruited from 1st March 2020 to 30th June 2022. Multilevel ordered logistic regression model statistics were performed.

PARTICIPANTS

Children (≥4 years, ≤16 years) undergoing tonsillectomy (with or without adenoidectomy) for benign pathology.

MAIN OUTCOME MEASURES

Frequency and severity of post-operative bleeding. Intensity and pattern of post-operative pain.

RESULTS

In total 297 children were recruited, with 91 (30.6%) diaries eligible for analysis. Post-operative bleeding occurred in 44% of children. Most frequently blood in the saliva was reported (82.9%). Increasing age significantly increased bleeding odds by 17% per year (p = .001). Bleeding frequency decreased with higher surgeon grade (p = .003) and when performing intracapsular coblation tonsillectomy (p = .02) compared with other techniques. Lower age and intracapsular coblation tonsillectomy, against other techniques, significantly reduced rates of pain post-operatively (p < .0001 and p = .0008).

CONCLUSION

A high level of low-level post-operative bleeding was observed. Pain scores remained high for 5 days post-operatively then gradually reduce to normal by day 13. Intracapsular coblation tonsillectomy appears to be superior to all other techniques in terms of reducing post-operative bleeding and pain. These findings should be used to guide patients in the consent process to inform them of the expected nature of post-surgical recovery.

Parents' perspective on recovery at home following adenotonsillectomy: a prospective single-centre qualitative analysis

PURPOSE

In North America, pediatric adenotonsillectomy (TA) is conducted as an ambulatory procedure, thus shifting the burden of postoperative care to parents. The purpose of this study was to describe this parental experience.

METHODS

We conducted a prospective single-centre qualitative study, recruiting the families of children (n = 317) undergoing elective TA in 2018. Parents were invited to submit written comments to two open-ended questions. We coded the comments from 144 parents in a grounded theory analysis and report representative exemplars. Themes and subthemes for the problems encountered, and strategies employed by parents, were developed. We then coded and classified factors that helped/hindered parents and developed models of the experience.

RESULTS

Some parents felt ill-prepared for the severity and duration of pain. Specific findings included a lack of strategies to manage pain at night, refusals, and night terrors. Parents identified the use of pain scales, pain diaries, and liaison with the research team as helpful supports at home. Inconsistent messaging was a barrier. The odynophagia associated with elixirs of acetaminophen and ibuprofen was a barrier to achieving analgesia.

CONCLUSIONS

The findings from this qualitative analysis provide insight into the challenges faced by parents when caring for their children at home following TA; these challenges included difficulties managing physical needs and pain. The analysis suggests that educational content should be standardized and include the use of pain scales and diaries, and both pharmacologic and nonpharmacologic strategies. Development of support at home, including a practicable liaison with health care providers, seems to be warranted.

Postoperative recovery in children: Turkish cross-cultural adaptation

BACKGROUND

Postoperative recovery is an individual process involving subjective experiences. The fact that children still experience high rates of complications associated with surgery requires the discovery of new evaluation methods. No studies in Turkey have reported a measurement instrument evaluating postoperative recovery in children. The purpose of this methodological study is to cross-culturally adapt the Postoperative Recovery in Children (PRiC) instrument into the Turkish language and test the validity and reliability of its Turkish version.

METHODS

One hundred children (81% male) aged 4 to 12 years undergoing tonsillectomy at a hospital were included. The self-administered PRiC and Parents' Postoperative Pain Measure (PPPM) instruments were used to collect data on the 1st, 4th, and 10th days after surgery. Internal consistency, parallel-forms reliability, content validity, and construct validity of the instruments were determined.

RESULTS

PRiC had a three-factor structure, and these factors explained 68% of the total variance in the variable it measured. It showed a high level of internal consistency (Cronbach's alpha = 0.842). The item-total score correlation coefficients for 23 of the items were ≥0.30. PRiC was moderately correlated with PPPM on the 1st day after surgery (r = 0.64, p < .01), on the 4th day after surgery (r = 0.69, p < .01), and on the 10th day after surgery (r = 0.51, p < .01).

CONCLUSION

The Turkish version of PRiC has good reliability and validity. A validity and reliability study of PRiC to assess children's postoperative recovery in the context of different surgical operations should be conducted.

Validation of the parent's postoperative pain measure with an age-appropriate reference pain scale for children 2-12 years old during a 14-day recovery after tonsillectomy: A prospective cohort study

BACKGROUND

Adenotonsillectomy is associated with severe postoperative pain. The parent's postoperative pain measure (PPPM), a 15-item instrument to measure a child's pain at home, has been validated with a seven-point faces scale in children 7-12 years and with the parents' global report of pain in children 2-6 years.

AIMS

Our primary objective was to validate the PPPM with a recommended age-appropriate pain scale in children 2-12 years after adenotonsillectomy. Our secondary objective was to reduce the PPPM components and validate this reduced PPPM.

METHODS

We recruited 319 children out of the 563 adenotonsillectomies performed between December 19, 2017, and December 18, 2018. Parents recorded administration of analgesics and their child's pain scores twice daily for 14 days: PPPM for all children and either the face, legs, arms, crying, consolability (FLACC) pain scale for children 2-3 years or the faces pain scale-revised (FPS-R) for children 4-12 years. In addition, parents recorded analgesics.

RESULTS

Among the 354 eligible children, 9% of parents declined. 252 (79%) families submitted pain diaries. The median age was 2.9 [2.5-3.3] years for FLACC (n = 114) and 5.6 [4.5-7.2] years for FPS-R (n = 138). Across the 14-day recovery period, Cronbach's alpha for PPPM was 0.77 to 0.87. Generalized linear mixed models evaluated the association between PPPM and reference pain scales after adjustment for potential confounders. Time of day and postoperative days were included as predictors in the models. PPPM was strongly associated with FLACC and FPS-R (beta coefficient = 0.4; p < 0.0001). The association decreased over time, and the reduction was more significant for FPS-R than FLACC (beta coefficient = -0.13 vs. -0.04, respectively; p < 0.0001). There was a positive association between PPPM and the use of analgesics. A reduction analysis eliminated items from the original PPPM: four for FLACC and five for FPS-R, suggesting age-related differences. The reduced PPPM instruments achieved similar associations with their respective reference pain scales (beta coefficient = 0.5; p < 0.0001).

CONCLUSIONS

This study extends previous work by validating the PPPM in children as young as 2 years with a recommended age-appropriate pain scale over 14-day convalescence after adenotonsillectomy. The reduced PPPM instruments differed in the two age groups. Future studies might explore these age-appropriate reduced PPPM instruments to assess pain at home following adenotonsillectomy.

Pain in children undergoing tonsillotomy with alternating ibuprofen and paracetamol - a prospective observational study

BACKGROUND

The optimal pain therapy for children undergoing tonsillotomy remains unknown. Our aim was to evaluate a standard pain therapy including the alternating application of ibuprofen and paracetamol.

METHODS

Pain intensity of 81 in-patients after tonsillotomy aged 2-12 years was evaluated three times daily (mean observation 3.85 days) using the Children's and Infants' Postoperative Pain Scale (CHIPPS) in children <5 years, or with the Faces Pain Scale-Revised (FPS-R) in older children. Parents completed the Parents' Postoperative Pain Measure (PPPM-D) in addition. Exceeding the cut-off value in one of the scores implied the indication for an opioid rescue medication (RM). Endpoints were number of children with indication for the RM, course of pain, concordance between pain scales, and adverse events.

RESULTS

Overall, 45.7% of children needed the RM either in the recovery room or on the ward. The rate of children having an indication for RM on the ward was 30.9%. The highest proportion of affected children was identified on the day of surgery (32.1%). Most indications were detected with the PPPM-D only. A comparison with an earlier study showed less affected children compared to ibuprofen monotherapy on the day of surgery and the first postoperative day. Eleven children (13.6%) developed fever.

CONCLUSION

Although our pain therapy concept was effective from postoperative day 1 onwards, it needs improvement for the day of surgery. The overall concordance between the PPPM-D and CHIPPS or FPS-R was low. Fever might be a confounder for the pain intensity measurement with the PPPM-D.

Trajectory of Pain, Functional Limitation, and Parental Coping Resources Following Pediatric Short-stay Surgery: Factors Impacting Rate of Recovery

OBJECTIVES

Although there are many benefits of short-stay hospital admissions for high volume, pediatric surgical procedures, this model of care places greater responsibility on parents for the management of children's pain. This study aimed to document the trajectory of child pain outcomes and a range of parent-reported functional outcomes following discharge from a short-stay surgical admission. Moreover, we aimed to document the trajectory of parental perceived personal coping resources. Second, we assessed whether parental dispositional factors, assessed before hospital discharge, predicted the child's pain intensity and parent-reported functional recovery.

METHODS

Participants included children (aged 4 to 14 y) admitted for a short-stay tonsillectomy or appendectomy, and their parents. Parents completed a questionnaire before discharge from hospital. Demographic and surgical information was recorded from medical records. Following discharge, daily assessments of pain and functioning were carried out over a 10-day period using iPods or mobile phones. Predischarge and postdischarge data were obtained for 55 child and parent dyads.

RESULTS

Pain intensity scores returned to low levels (2/10 or less) by day 5 for appendectomy and day 10 for tonsillectomy. Parents' perceived personal coping resources increased more slowly following tonsillectomy than appendectomy. Controlling for time since surgery and parental coping resources, parental pain-related catastrophizing was a significant predictor of child pain and functional recovery.

DISCUSSION

Short-stay surgery results in parents facing considerable burden in managing their child's pain and functional impairment over a 10-day period. The potential value of screening for parental pain-related catastrophizing before discharge from hospital warrants further consideration and may enable identification of children likely to experience poorer recovery.

Impact of a revised postoperative care plan on pain and recovery trajectory following pediatric tonsillectomy

BACKGROUND

A previous cohort of adenotonsillectomy patients at our institution demonstrated moderate-severe post-tonsillectomy pain scores lasting a median (range) duration of 6 (0-23) days and postdischarge nausea and vomiting affecting 8% of children on day 1 following surgery. In this subsequent cohort, we evaluate the impact of changes to our discharge medication and parental education on post-tonsillectomy pain and recovery profile.

METHODS

In this follow-on, prospective observational cohort study, all patients undergoing tonsillectomy at our institution during the study period were discharged with standardized analgesia. Parents received a revised education package and a medication diary which were not provided to the previous cohort. Pain scores, rates of nausea and vomiting, medication usage and unplanned representation rates were collected by telephone from parents.

RESULTS

Sixty-nine patients were recruited. Moderate-severe pain lasted a median (range) of 5 (0-12) days. Twenty-nine (42%) had pain scores ≥4/10 beyond postoperative day 7. By postoperative day 5, only 37 (53%) parents continued to administer regular analgesia. The median number of oxycodone doses used was 5 (0-22), and only 28 (41%) parents had disposed of leftover oxycodone within 1 month of surgery. Twenty-four (35%) patients experienced nausea or vomiting postdischarge. The median (range) time for return to normal activities was 6 (0-14) days. Thirty-two/sixty-nine (46%) patients had unplanned medical representations. Most occurred between postoperative day 5 and 7. Pain contributed to 16 (35%) representations.

CONCLUSIONS

Despite extensive changes to our discharge protocols parents continued to report a prolonged period of pain, post operative nausea and vomiting, and behavioral changes. Further work is required to examine barriers to compliance with simple analgesia and education in appropriate methods of opioid disposal.

Patterns of dispensed opioids after tonsillectomy in children and adolescents in South Carolina, United States, 2010-2017

OBJECTIVES

Tonsillectomy (with or without adenoidectomy) is a common pediatric surgical procedure requiring post-operative analgesia. Because of the respiratory depression effects of opioids, clinicians strive to limit the use of these drugs for analgesia post-tonsillectomy. The objective of this study was to identify demographic and medication use patterns predictive of persistent opioid dispensing (as a proxy for opioid use) to pediatric patients post-tonsillectomy.

PATIENTS AND METHODS

Retrospective cohort of South Carolina (USA) Medicaid-insured children and adolescents 0-18 years old without malignancy who had tonsillectomy in 2014-2017. We evaluated opioid dispensing pre-surgery and in the 30 days exposure period after hospital discharge. The main outcome, persistent opioid dispensing, was defined as any subject dispensed ≥1 opioid prescription 90-270 days after discharge. Group-based trajectory analyses described post-procedure opioid dispensing trajectories.

RESULTS

There were 11,578 subjects representing 12,063 tonsillectomy procedures. Few (3.5%) procedures were followed by persistent opioid dispensing. Any opioid dispensing during the exposure period was associated with an increased odds of persistent opioid dispensing status during the follow up period (OR 1.51 for 1-6 days of exposure and OR 1.65 for 7-30 days of opioid exposure), as was pre-procedure opioid dispensing, having >1 tonsillectomy procedure, and having complex chronic medical conditions. Group-based trajectory analyses identified 4 distinct patterns of post-discharge opioid dispensing.

CONCLUSIONS

Any opioid dispensing during the 30 days after tonsillectomy increased the odds of persistent opioid dispensing by > 50%. Multivariable and group-based trajectory analyses identified patient and procedure variables that correlate with persistent opioid dispensing, primarily driven by groups receiving pre-tonsillectomy opioids and a second group who experienced multiple episodes of tonsillectomy.
