Parental assessment of pain control following pediatric adenotonsillectomy: Do opioids make a difference?

Postoperative prescribing of opioids following pediatric adenotonsillectomy can have negative consequences including unnecessary opioid exposure and potential for respiratory depression. While guidelines from The American Academy of Otolaryngology/Head & Neck Surgery recommend treatment of post adenotonsillectomy pain using acetaminophen and ibuprofen, many providers continue to prescribe opioids and may do so, in part with concern for parental dissatisfaction with post-operative analgesia. Our aim was to determine whether a post-operative prescription for opioids affects parental assessment of pain control following pediatric adenotonsillectomy. This post-operative survey assessed the parental assessment of pain control in 324 patients, ages 1-17 years undergoing adenotonsillectomy. This study was conducted at a quaternary care children's hospital in Houston, Texas from December 1, 2018 through March 31, 2019. Post-operative pain regimens included acetaminophen and ibuprofen or combination hydrocodone/acetaminophen in addition to ibuprofen for post-operative analgesia based on the attending surgeons prescribing preferences. The primary study outcome was identification of the proportion of parents rating their child's analgesia following pediatric adenotonsillectomy as poor or inadequate based on the post-operative analgesic regimen including opioids. Of the 798 surveys sent, the response rate was 42% (324/775) of those who received the survey email, and 69% (324/470) for those who opened the email. Between the opioid and non-opioid groups, there was no difference in gender (male; 48% vs. 51.3%; p = 0.58), race/ethnicity (white; 53% vs. 46%; p = 0.35) or insurance status (insured; 62% vs. 50.9%; p = 0.06). The proportion of parents who rated their child's pain as poor or inadequately controlled following adenotonsillectomy was relatively rare: 9% and 5% in the non-opioid and opioid groups, respectively. Parents rating their child's pain as excellent with regards to pain control following adenotonsillectomy were 58% and 50% in the non-opioids and opioid groups respectively. The results of this study indicate that non-opioid analgesic regimens following pediatric adenotonsillectomy were not associated with decreased parental satisfaction or an increasing assessment of poor or inadequately controlled pain. Limiting opioid exposure following pediatric adenotonsillectomy is feasible and does not result in worse parental satisfaction with the analgesic plan.

Parental Assessment of Pain Control Following Pediatric Circumcision: Do Opioids Make a Difference?

To determine whether a postoperative prescription for opioids affects parental assessment of pain control following pediatric circumcision. This postoperative survey assessed the parental assessment of pain control in 199 patients, ages<18 years undergoing circumcision. This study was conducted at a quaternary care children's hospital in Houston, Texas from December 2018 to January 2020. Postoperative pain regimens included acetaminophen and ibuprofen or combination hydrocodone/acetaminophen in addition to ibuprofen for postoperative analgesia based on the surgical preference. The primary study outcome was identification of the proportion of parents rating their child's analgesia following pediatric circumcision as poor or inadequate based on the postoperative analgesic regimen. Of the 502 surveys sent, the response rate was 40% (199/502) of those who received the survey email, and 64% (199/308) for those who opened the email. Between the opioid and nonopioid groups, there was no difference in, race/ethnicity (Caucasian; 28% vs 37%; P = .43) or insurance status (insured; 51% vs 45%; P = .44). The proportion of parents who rated their child's pain as poor or inadequately controlled following circumcision was relatively rare:5.5% and 1.1% in the nonopioid and opioid groups, respectively. Parents rating their child's pain as excellent with regards to pain control following circumcision were 61% and 53% in the nonopioids and opioid groups, respectively. The results of this study indicate that nonopioid analgesic regimens following pediatric circumcision were not associated with decreased parental satisfaction or an increasing assessment of poor or inadequately controlled pain. Limiting opioid exposure following pediatric circumcision is feasible and does not result in worse parental satisfaction with the analgesic plan.

Primary Caregiver Perception of Pain Control following Pediatric Adenotonsillectomy: A Cross-Sectional Survey.

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. Case series with planned data collection. Multihospital network. 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. 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. 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.

The development of an opioid sparing anesthesia protocol for pediatric ambulatory tonsillectomy and adenotonsillectomy surgery-A quality improvement project.

Pain management following pediatric tonsillectomy and adenotonsillectomy surgery is challenging and traditionally involves perioperative opioids. However, the recent national opioid shortage compelled anesthesiologists at Bellevue Surgery Center to identify an alternative perioperative analgesic regimen that minimizes opioids yet provides effective pain relief. We assembled an interdisciplinary quality improvement team to trial a series of analgesic protocols using the Plan-Do-Study-Act cycle. Initially, we replaced intraoperative morphine and acetaminophen (M/A protocol) with intraoperative dexmedetomidine and preoperative ibuprofen (D/I protocol). However, when results were not favorable, we rapidly transitioned to intraoperative ketorolac and dexmedetomidine (D/K protocol). The following measures were evaluated using statistical process control chart methodology and interpreted using Shewhart's theory of variation: maximum pain score in the postanesthesia care unit, postoperative morphine rescue rate, postanesthesia care unit length of stay, total anesthesia time, postoperative nausea and vomiting rescue rate, and reoperation rate within 30 days of surgery. There were 333 patients in the M/A protocol, 211 patients in the D/I protocol, and 196 patients in the D/K protocol. With the D/I protocol, there were small increases in maximum pain score and postanesthesia care unit length of stay, but no difference in morphine rescue rate or total anesthesia time compared to the M/A protocol. With the D/K protocol, postoperative pain control and postanesthesia care unit length of stay were similar compared to the M/A protocol. Both the D/I and D/K protocols had reduced nausea and vomiting rescue rates. Reoperation rates were similar between groups. In summary, we identified an intraoperative anesthesia protocol for pediatric tonsillectomy and adenotonsillectomy surgery utilizing dexmedetomidine and ketorolac that provides effective analgesia without increasing recovery times or reoperation rates.

Comparison of Oral Loading Dose to Intravenous Acetaminophen in Children for Analgesia After Tonsillectomy and Adenoidectomy: A Randomized Clinical Trial.

Acetaminophen is a frequently used adjunct analgesic in pediatric patients undergoing tonsillectomy and adenoidectomy. We compared opioid administration following preoperative intravenous (IV) or oral acetaminophen in addition to a standard multimodal regimen to test the hypothesis that 1 loading dose approach would provide superior opioid sparing effects among pediatric surgical patients undergoing tonsillectomy and adenoidectomy. This single-center, double-blind, double-dummy prospective randomized study was conducted in patients ages 3 to 15 years undergoing tonsillectomy and adenoidectomy with or without myringotomy and tube placement between September 2017 and July 2019. Subjects received 1 dose of either oral acetaminophen 30 mg/kg with IV placebo (oral group) or IV acetaminophen 15 mg/kg with oral placebo (IV group). Acetaminophen plasma levels were measured at 2 timepoints to evaluate safety and determine plasma levels attained by each dosing regimen. Intraoperative opioid administration and postoperative analgesia were standardized. Standardized postoperative multimodal analgesia included opioid if needed to control pain assessed by standardized validated pediatric pain scales. The primary outcome measure was total opioid administration in the first 24 hours after surgery. Continuous data were not normally distributed and were analyzed using the Wilcoxon rank sum test and the Hodges-Lehman estimator of the median difference. Clinical significance was defined as a 100 µg/kg IV morphine equivalents per day difference. Sixty-six subjects were randomized into and completed the study (29 women, 37 men; age 5.9 ± 3.0 years; percentile weight for age 49.5 ± 30.2; no differences between groups). There was no opioid dose difference between oral (median 147.6; interquartile range [IQR], 119.6-193.0 µg/kg) and IV groups (median 125.4; IQR, 102.8-150.9 µg/kg; median difference 21.3; 95% confidence interval [CI] -2.5 to 44.2 µg/kg IV morphine equivalents; P = .13). No acetaminophen levels exceeded the predefined safety threshold (40 mg/L). No difference was found in the percentage of patients with severe pain: 50.0% oral group, 47.2% IV group; relative risk of severe pain in IV 0.94; 95% CI, 0.57-1.6; P = .82. Postoperative plasma acetaminophen levels were higher in oral (22; IQR, 16-28 mg/L) than IV (20; IQR, 17-22 mg/L) group (median difference 7.0; 4.0-8.0 mg/L; P = .0001). Opioid-sparing effects did not differ following an oral or standard IV acetaminophen loading dose with no identified acetaminophen toxicity in pediatric patients undergoing tonsillectomy and adenoidectomy who received standardized multimodal postoperative analgesia. An oral loading dose may provide more consistent serum acetaminophen levels at lower cost compared to a standard IV dose.
