Opioid-free anesthesia for adenotonsillectomy in children

The effect of two different video demonstrations on pain and anxiety in children undergoing adenotonsillectomy: A randomized controlled trial

AIM

The study was conducted to determine the effect of two different video demonstrations on pain and anxiety in children undergoing adenotonsillectomy.

METHODS

This randomized controlled trial (NCT06339866) was conducted by randomly assigning children aged 6-12 years who underwent adenotonsillectomy to three groups (animation group = 34, cartoon group = 32 and control group = 32). Data were collected using Sociodemographic Questionnaire, Wong-Baker Faces Pain Rating Scale, Child Anxiety Scale-Conditioning (CAS-C).

RESULTS

The pain score of the children in the control group was found to be significantly higher than that of the other groups (p < 0.05). Furthermore, the pain score of the children in the cartoon group was found to be significantly higher than that of the children in the educational animation group (p < 0.05). In all of the parent and nurse assessments, the mean scores of the children in the education group were found to be lower after surgery compared to the preoperative period (p < 0.001). A negative correlation was observed between Wong-Baker Faces Expressions Pain Rating Scale scores and change in CAS-C scores (p < 0.05). The changes in CAS-C scores accounted for 26.1 % of the total variance in pain scores according to the children's assessment, 19.0 % according to the parents' assessment, and 42.6 % according to the nurses' assessment. The intraclass correlation analysis was conducted to assess the agreement between the mean scores of children, parents, and nurses on the Wong-Baker Faces Expressions Pain Rating Scale and the CAS-C. The results demonstrated excellent agreement (p < 0.001).

CONCLUSION

The use of educational animation and cartoons in the preoperative period has a significant effect on reducing postoperative anxiety and pain levels in children. The use of educational animation was found to be the most effective method. In future studies, it is recommended that more impressive videos and presentations with technological developments be used comparatively both in children undergoing adenotonsillectomy and in children undergoing different surgical procedures.

Perioperative opioids in high-risk children undergoing tonsillectomy - A single institution experience

BACKGROUND

Patients undergoing tonsillectomy/ adenotonsillectomy (T/AT) can experience substantial postoperative pain. The aims of this study are to assess perioperative pain management in high-risk children (children with severe obstructive sleep apnea and other complex medical comorbidities or age younger than 2 years) undergoing T/AT, and the impact on oxygen levels and pain during extended Post-Anesthesia Care Unit (PACU) admission.

METHODS

A retrospective case series study at a tertiary care children's hospital.

RESULTS

There were 278 children enrolled in the study. The Apnea-Hypopnea index and mean oxygen nadir on preoperative polysomnography were 31.3 ± 25.76/h and 79.5 ± 9.5 % respectively. Overall, 246 (89 %) patients received intraoperative opioids alone (n = 35, 13 %) or in combination with non-opioid analgesia (n = 209, 75 %). While the median dose of opioid-free medications (acetaminophen, ibuprofen) ranged from 93 to 100 % of standard maximal dosing by weight and age, the median dose of opioids was significantly lower and ranged from 54 to 63 % of standard maximal dosing by weight and age, with 43 % of the patients receiving less than half the recommended maximum dose. Oxygen desaturation was charted in 21 patients (8 %) during their PACU admission. Patients who received opioid-free analgesia were as likely to develop oxygen desaturations (n = 17 (81 %) vs. n = 228 (89.4 %), p = 0.27) and to receive rescue pain medication during their PACU stay as patients who received opioids intraoperatively (n = 18 (56 %) vs. n = 167 (68 %), p = 0.23).

CONCLUSIONS

Intraoperative pain management varies across high-risk pediatric tonsillectomies. Opioid-free analgesia was not associated with an increased need for pain medications during PACU admission, or with a decreased likelihood of oxygen desaturations compared to intra-operative opioid analgesia use.

Optimizing pediatric tonsillectomy outcomes with an opioid sparing anesthesia protocol: Learning and continuously improving with real-world data

INTRODUCTION

This quality improvement initiative is a continued pursuit to optimize outcomes by iteratively improving our opioid sparing anesthesia protocol for tonsillectomy with or without adenoidectomy at our pediatric ambulatory surgical center through data driven Plan-Do-Study-Act cycles.

METHODS

From 1/2015 through 12/2023, our standardized tonsillectomy protocol underwent nine procedure-specific perioperative Plan-Do-Study-Act cycles, three procedure-specific postoperative prescription Plan-Do-Study-Act cycles, and four general ambulatory surgical center enhanced recovery Plan-Do-Study-Act cycles. We analyzed data from the medical record using statistical process control charts. The primary outcome measure was the percent of patients requiring intravenous opioid in the post anesthesia care unit. Secondary outcomes included maximum post anesthesia care unit pain score, the percent of patients requiring treatment for nausea and/or vomiting in the post anesthesia care unit, and the number of postoperative opioid prescription dosages. Balancing measures were average post anesthesia care unit length of stay, percent of patients with prolonged Post Anesthesia Care Unit length of stay (>120 min), and 30-day reoperation rate.

RESULTS

A total of 5654 tonsillectomy with or without adenoidectomy cases were performed at our ambulatory surgical center from 2015 to 2023. The incidence of intravenous opioid administered in the post anesthesia care unit initially rose with opioid free anesthesia launch, but subsequently decreased below the target of 10%. Maximum post anesthesia care unit pain scores rose from mean 3.6 to 4.5, but subsequently returned to the baseline of 3.5, while the incidence of postoperative nausea and/or vomiting improved. The average post anesthesia care unit length of stay increased by 10 min with opioid free anesthesia; however, prolonged post anesthesia care unit stay and 30-day reoperation rates were unchanged.

CONCLUSIONS

The continued refinement of our opioid sparing anesthesia protocol has led to reduced perioperative and home opioid use, stable maximum post anesthesia care unit pain scores, and improved postoperative nausea and vomiting rates, with only a slight increase in mean post anesthesia care unit length of stay.

Updating Clinical Practice: Improving Perioperative Pain Management for Adeno-Tonsillectomy in Children

BACKGROUND/OBJECTIVE

Perioperative acute pain management in pediatric patients is essential to reduce complications. Adenoidectomy-Tonsillectomy are surgical procedures requiring pain control, and risk minimization for postoperative bleeding, nausea, and vomiting. Despite their known secondary effects, the use of opioid analgesics is still preponderant in pediatric perioperative management. We performed a comprehensive review on adeno-tonsillectomy perioperative pain management in children. We developed and implemented a multimodal analgesia protocol aimed to improve patients' pain management while consistently reducing opioids use.

METHODS/RESULTS

relevant Information was summarized, then compared to our clinical needs. Learnings were used to create and implement a multimodal analgesia protocol that we use in patients 3-9 years-old undergoing adenoidectomy/tonsillectomy. The full protocol is presented. Analgesic strategies have emerged to reduce or avoid the use of opioids. Among these strategies, combining different non-opioid analgesics (Ibuprofen, Paracetamol, Metamizole) has been shown to be an effective and safe pharmacological strategy when implemented as part of perioperative multimodal analgesia protocols. Considerable evidence associating the use of NSAIDs with a bigger risk of postoperative bleeding does not exist.

CONCLUSIONS

Perioperative management of adenotonsillectomy pain should include preventive and multimodal analgesia, which have shown to provide significantly more effective analgesia than some opioid regimens. Ibuprofen offers highly effective analgesia for postoperative pain, particularly when combined with acetaminophen.

Care of the Pediatric Patient for Ambulatory Tonsillectomy With or Without Adenoidectomy: The Society for Ambulatory Anesthesia Position Statement

The landscape of ambulatory surgery is changing, and tonsillectomy with or without adenoidectomy is one of the most common pediatric surgical procedures performed nationally. The number of children undergoing tonsillectomy on an ambulatory basis continues to increase. The 2 most common indications for tonsillectomy are recurrent throat infections and obstructive sleep-disordered breathing. The most frequent early complications after tonsillectomy are hemorrhage and ventilatory compromise. In areas lacking a dedicated children's hospital, these cases are managed by a nonpediatric specialized anesthesiologist and general otolaryngology surgeon. In response to requests from our members without pediatric fellowship training and/or who care for pediatric patients infrequently, the Pediatric Committee of the Society for Ambulatory Anesthesia (SAMBA) developed a position statement with recommendations for the safe perioperative care of pediatric patients undergoing tonsillectomy with and without adenoidectomy in freestanding ambulatory surgical facilities. This statement identifies children that are more likely to experience complications and to require additional dedicated provider time that is not conducive to the rapid pace and staffing ratios of many freestanding ambulatory centers with mixed adult and pediatric practices. The aim is to provide health care professionals with practical criteria and suggestions based on the best available evidence. When high-quality evidence is unavailable, we relied on group consensus from pediatric ambulatory specialists in the SAMBA Pediatric Committee. Consensus recommendations were presented to the Pediatric Committee of SAMBA.

Opioid Free Ptyregopalatine Ganglion Block Based Multimodal Anesthesia Versus Conventional Opioid Based Multimodal Anesthesia for Tonsillectomy Operations: A Randomized Controlled Trial

Background

Otolaryngology often involves adenotonsillectomies, surgical procedures aimed at addressing obstructive sleep-disordered breathing and underlying apnea in children.

Objectives

Pediatric anesthesiologists and otolaryngologists encounter challenges in managing pain post-adenotonsillectomy, especially due to the use of opioid medications in children who have an elevated baseline risk of airway obstruction and associated morbidity and mortality.

Methods

This prospective, randomized, double-blinded study was conducted at Eldemerdash Hospital, Ain Shams University, Egypt, from September 2022 to August 2023. A total of 90 patients aged 5 - 13 years who underwent elective tonsillectomy surgery were randomly assigned to two groups, with 45 patients in each group. The first group, referred to as group A, received intravenous 1.0 μg/kg fentanyl, dexamethasone 150 μg/kg, and paracetamol 15 mg/kg. The second group, referred to as group B, received dexamethasone 150 μg/kg and paracetamol 15 mg/kg, with an opioid-free pterygopalatine ganglion block for multimodal anesthesia. The primary outcome measure of this study was the postoperative Wong-Baker scale at 1st, 3rd, and 24th hours.

Results

This study included 90 individuals with similar demographic profiles and comparable initial characteristics and surgical techniques in both groups (P > 0.05). Intraoperative heart rate, mean blood pressure, additional analgesia, postoperative Wong-Baker scale, postoperative rescue analgesia, and laryngospasm did not show significant differences between the two groups (P > 0.05). However, there were statistically significant differences between the groups in terms of nausea, vomiting, hypoxia, and post-anesthesia care unit stay, with group B experiencing fewer of these issues (P < 0.05).

Conclusions

Both conventional opioid-based multimodal anesthesia and opioid-free pterygopalatine ganglion block-based multimodal anesthesia are effective methods for providing analgesia during and after tonsillectomy surgery. The pterygopalatine ganglion block, the latter option, has been found to result in fewer postoperative complications such as nausea, vomiting, and hypoxia. Additionally, patients who receive this type of anesthesia typically require less time in the post-anesthesia care unit.

Perioperative clinical practice recommendations for pediatric tonsillectomy: a systematic review

PURPOSE

Tonsillectomy is one of the most common surgical procedures performed in children. Since most clinical practice guidelines (CPGs) are designed to support surgical decisions, none are specifically designed for the perioperative management of children undergoing tonsillectomy. We aimed to identify and analyze the existing CPGs with recommendations for the perioperative management of children undergoing tonsillectomy by conducting a systematic review.

SOURCE

We searched Embase, MEDLINE, MEDLINE ePub Ahead of Print, and CINAHL for relevant articles published from inception to 3 August 2022. The inclusion criteria were: 1) CPG of perioperative recommendations for tonsillectomy under general anesthesia in children, 2) CPG that include at least one evidence-based recommendation, 3) peer-reviewed CPG published in English after 2000. We extracted data on baseline characteristics of each CPG and general recommendations for perioperative interventions or complications.

PRINCIPAL FINDINGS

Out of five eligible CPGs, AGREE II and REX confirmed that two CPGs were high quality while only one of the two was recommended for implementation without modifications. Most of the recommendations were for pain management. Acetaminophen was the only medication recommended in all five CPG. Except for the oldest CPG, the CPG all supported of the use of nonsteroidal anti-inflammatory drugs and steroids as a pain adjunct.

CONCLUSIONS

Acetaminophen, nonsteroidal anti-inflammatory drugs, and steroids are recommended in the perioperative management of pediatric tonsillectomy. Future CPG should further clarify the safe use of opioids based on severity of obstructive sleep apnea and in the context of opioid-sparing techniques, such as dexmedetomidine, high-dose dexamethasone, and gabapentinoids.

The association of intraoperative opioid dose with postanesthesia care unit outcomes in children: a retrospective study

PURPOSE

In children, the relationship between the dose of intraoperative opioid and postoperative outcomes is unclear. We examined the relationship between intraoperative opioid dose and postanesthesia care unit (PACU) pain scores and opioid and antiemetic administrations.

METHODS

We performed a single-institution retrospective cohort study. Patients who were aged < 19 yr, had an American Society of Anesthesiologists Physical Status of I-III, were undergoing one of 11 procedures under general anesthesia and without regional anesthesia, and who were admitted to the PACU were included. Patients were analyzed by quartiles of total intraoperative opioid dose using multivariable regression, adjusting for confounders including procedure. An exploratory analysis of opioid-free anesthetics was also performed.

RESULTS

Three thousand, seven hundred and thirty-three cases were included, and the mean age of included patients was 8.3 yr. After adjustment, there were no significant differences between the lowest and higher quartiles for first conscious pain score, mean pain score, PACU opioid dose, or PACU length of stay; in addition, estimated differences were small. Patients in higher quartiles were estimated to be more likely to receive antiemetics, significantly so for those in the second quartile. Patients in the lowest quartile received significantly more intraoperative nonopioid analgesics. In the exploratory analysis, no significant difference in PACU pain scores was found in cases without intraoperative opioids.

CONCLUSIONS

Children who received lower doses of intraoperative opioids did not have worse PACU pain outcomes but required fewer antiemetics and received greater numbers of nonopioid analgesics intraoperatively. These findings suggest that lower doses of intraoperative opioids may be administered to children as long as other analgesics are used.

Opioid stewardship and perioperative management of pediatric tympanoplasty

OBJECTIVE

To provide insight into the intraoperative management, admission course, pain management, and graft success of microscope- and endoscope-assisted tympanoplasty.

STUDY DESIGN

Retrospective Chart Review.

METHODS

This study included children 18 years and younger who underwent ambulatory tympanoplasty at a tertiary pediatric hospital between January 2018 and December 2020. Medical records were reviewed and information about intraoperative factors, surgical approach, laterality, complications, and post-operative perforation closure success rates was collected. Multivariate analysis was performed to compare and contrast the two surgical approaches.

RESULTS

The review included 321 pediatric patients who underwent a tympanoplasty. Endoscopic tympanoplasty accounted for 17.4%, while microscopic tympanoplasty accounted for 82.6%. In both approaches, the rate of intraoperative complications, postoperative complications, audiological improvements, and perforation closure success rates were statistically similar. However, patients who underwent endoscopic tympanoplasty were 3.96 times less likely to require opioids in the post-anesthesia care unit (PACU) and had a shorter post-operative admission length. This pattern emerged regardless of the type of graft used. Obtaining an autograft was not associated with a higher opioid requirement in the PACU.

CONCLUSION

While both approaches are viable, our findings demonstrate the reduced need for opioids with similar success rates following an endoscopic tympanoplasty. Ultimately, the trade-off for the minimally invasive endoscopic approach appears to be a less painful experience for the child while promoting clinically appropriate opioid stewardship in the perioperative setting.

The effect of anesthesia without opioid on perioperative opioid demand in children with severe obstructive sleep apnea (OSA) for adenotonsillectomies — single-center retrospective observational study

Background

Children with severe obstructive sleep apnea (OSA) carry a higher risk of respiratory complications after adenotonsillectomy. Their altered sensitivity to opioids may be a significant contributor to respiratory morbidity. The purpose of this study was to identify how anesthesia without opioids affects perioperative opioid demand and postoperative course.

Methods

A chart review of children with severe OSA (apnea hypoxia index; AHI ≥ 10) undergoing adenotonsillectomies was performed. Comorbidities and perioperative medications were documented. Perioperative opioid doses within 48 h of procedure were calculated as morphine equivalents (mcg/kg). Pain scores, rescue medications, and postoperative complications in PICU and non-PICU settings were also documented. Anesthesia without opioid and with opioid groups were compared.

Results

The analysis included 225 children. A significantly higher percentage of children received no postoperative opioids in the anesthesia without opioid group compared to those with opioid (46 of 88 children vs. 43 of 137; P < 0.05). The incidence of severe postoperative pain between the two groups was not different in PICU (P = 0.88) or non-PICU setting (P = 0.84). Perioperative opioid administration was significantly lower in anesthesia without opioid (median, Q1, Q3: 0.0, 0.0, 83.0) compared to with opioid (144.4, 72.5, 222.2; P < 0.01). Anesthesia without opioid was one of the independent factors to achieve perioperative opioid avoidance (<50mcg/kg).

Conclusions

Anesthesia without opioid for children with severe OSA for tonsillectomy significantly reduced perioperative demand for opioid and did not affect the occurrence of severe pain. Anesthesia without opioid is an effective strategy to minimalize opioid demand perioperatively for children with severe OSA for tonsillectomy.

The Utilization of an Opioid-Free Anesthetic for Pediatric Circumcision in an Ambulatory Surgery Center

Circumcision is one of the most common urologic procedures performed at pediatric ambulatory centers. Emerging data on the short- and long-term effects of perioperative opioid administration has highlighted the importance of an opioid-free anesthetic regimen. We sought to evaluate the effectiveness of an opioid-free anesthetic in pediatric circumcision and its correlation with ambulatory surgery center efficiency. Patients, 3 years of age and younger, who underwent circumcision or circumcision revision by two surgeons pre and post introduction of an opioid-free anesthetic fast-track regimen at an outpatient surgical center were included. There were 100 patients included in this analysis, with 50 patients in each cohort. On univariate analysis, fast-tracking was associated with a decrease in median combined in-room and post-anesthesia care unit times (102.5 vs. 129.0 min, p-value < 0.001). This difference continued after multivariable analysis with an adjusted median combined in-room and post-anesthesia care unit time difference of -15.6 min (95% CI -34.2 to -12.7 min, p-value 0.018). In addition, the fast-track cohort received less intraoperative morphine equivalents without an increase in post-operative analgesic administration or change in postoperative questionnaire score. This demonstrates that opioid-free anesthesia may be used effectively in pediatric circumcision while also allowing for significant time savings for surgical centers.
