Background and objectives: Brachial plexus block is one of the most effective anesthesia and analgesia methods for upper extremity surgeries across different age groups. However, the number of studies on this block in children is insufficient. The aim of this study was to retrospectively analyze and discuss the efficacy and safety of ultrasound (US)- and Ultrasound with nerve stimulator (US + NS)-guided infraclavicular brachial plexus block (ICB) in pediatric patients. Materials and Method: In this study, we retrospectively analyzed the data of 240 pediatric patients admitted to our clinic between October 2020 and April 2023, 120 of whom underwent US-guided ICB and 120 who underwent US + NS-guided ICB. Results: Demographic data of both groups who underwent US and US + NS-guided ICB were similar. The mean procedure time was 6.1 ± 0.8 min for the US group and 8.31 ± 0.82 min for the US + NS group (p < 0.001). The mean operative time was 62.4 ± 11.3 min in the US group and 62.4 ± 9.5 min in the US + NS group (p = 0.73). Intraoperative and postoperative opioid and additional analgesia use and pain scores at 1, 3, 6, 9, 12, 15, and 24 h were recorded in both groups. The mean duration of the motor block (MBD) was 6.20 ± 0.95 h in the US group and 6.29 ± 0.88 h in the US + NS group (p = 0.46). The mean duration of sensory block (SBD) was 9.38 ± 2.13 h in the US group and 9.53 ± 2.05 h in the US + NS group (p = 0.38). Conclusions: In pediatric patients, US and US + NS-guided ICB applications are effective and safe in ease of application, prolonged analgesia, and low complication rates. In skilled hands, US-guided ICB can be as effective as US + NS-guided ICB. Further prospective studies with more significant patient populations are needed to validate these findings. Full article

Introduction: Methadone is an opioid-sparing opioid and it is increasingly used in children undergoing surgery due to its beneficial effects on postoperative pain scores, decreased opioid requirements, and fewer adverse effects compared to other opioids. Intraoperative methadone is not well studied in pediatric cardiac surgery. We hypothesized that intraoperative methadone-based analgesia would provide comparable effectiveness in pain management to non-methadone-based analgesia, including caudal morphine, following pediatric cardiac surgery. Methods: We conducted a retrospective cohort study of 287 children undergoing cardiac surgery using single institutional electronic health records with Society of Thoracic Surgeons database outcomes. Patients were administered intravenous opioids plus caudal morphine (≤6 years) or intravenous opioids in the non-methadone group versus intravenous methadone (two 0.1 mg/kg doses given intraoperatively) with or without additional intraoperative opioids. The primary outcome was postoperative opioid use in morphine milligram equivalents (MME)/kg. Results: This study included 287 pediatric cardiac surgical patients with a mean age of 3.8 years, 59% male, and 72% White. Among 287 patients, 67 (23%) received intraoperative methadone. Unadjusted analysis showed the methadone group had lower postoperative opioid use on the day of surgery (median = 0.3 vs. 0.5 MME/kg, p = 0.005). Adjusted analyses showed there were no significant differences in postoperative opioid use, average pain, maximum pain, antiemetic use, reintubation, and use of naloxone between methadone and non-methadone groups. Hospital length of stay was 2.62 times longer (95% CI: [1.55, 4.41] p < 0.001) in the methadone group vs non-methadone group, but this was only shown in the younger children (≤6 years), who also had higher max pain scores in the methadone group. All outcomes were similar between analgesia groups in older children (>6 years). Conclusions: Intraoperative methadone-based analgesia had comparable effectiveness in postoperative opioid use, pain, and antiemetic use compared to non-methadone-based intraoperative pain management for pediatric cardiac surgery. Large prospective studies of perioperative methadone are needed to examine methadone’s analgesic benefits in children undergoing cardiac surgery. Full article

Pain management in children remains a challenge. Postoperative pain assessment, which currently relies on behavioral and subjective scales, could be enhanced by the identification of single nucleotide polymorphisms effect on pain thresholds and opioid metabolism. This study explores the impact of nine SNPs—rs1799971, rs4680, rs4633, rs6269, rs4818 (with catechol-o-methyltransferase haplotypes), rs7832704, rs1801253, and rs1045642—on postoperative pain intensity, opioid requirements, coanalgesic use, C-reactive protein levels, and post-anesthesia care unit length of stay. This study involved 42 pediatric patients undergoing scoliosis correction surgery with postoperative sufentanil infusion. The genotyping was performed using real-time PCR with peripheral blood samples. Patients with the rs1801253 ADRB1 GG genotype showed significantly lower 24 h NRS pain ratings (p = 0.032) and lower sufentanil infusion rates at the level of statistical tendency (p = 0.093). Patients with the rs1205 CRP CT genotype had a shorter PACU length of stay (p = 0.012). In contrast, those with the rs1045642 ABCB1 GG genotype had a longer PACU stay by 0.72 h (p = 0.046). No significant associations were found for OPRM1 rs1799971, COMT, or ENPP2 SNPs. ADRB1 rs1801253may be a novel SNP indicating higher postoperative pain risk, while rs1205 CRP and rs1045642 ABCB1 could predict increased care requirements in PACUs. The ADRB1 rs1801253 SNP may also predict opioid demand. These results suggest SNPs should be considered in acute pain assessment. Full article

Background: Iatrogenic withdrawal syndrome (IWS) poses a significant clinical challenge in pediatric intensive care units (PICUs) within Japan. Despite the existing availability of tools to assess pain and delirium, a validated instrument specifically designed for IWS has been notably absent in Japanese clinical practice. The Sophia Observation withdrawal Symptoms-Paediatric Delirium (SOS-PD) scale is globally recognized as an effective tool for IWS evaluation. To bridge this gap, this study aimed to validate the Japanese version of the SOS-PD scale. Methods: A prospective, cohort, observational study was undertaken in a single-center PICU in Japan. Participants ranged from neonates to children aged 20 years, excluding those with pre-existing neurological conditions or coma. Criterion validity was evaluated by comparing Japanese SOS-PD scale scores between a Weaning Group (WEAN) undergoing sedative/opioid tapering and a Maintenance Group (MAIN) receiving stable medication. Correlation analysis was also conducted against pediatric intensivists’ observational NRS (NRSobs). Inter-rater reliability of the Japanese SOS-PD scale was assessed utilizing kappa statistics and intraclass correlation coefficient (ICC). Results: In support of criterion validity, the WEAN group demonstrated significantly higher scores in both NRSobs and the IWS component of the Japanese SOS-PD scale compared to the MAIN group (p < 0.001). A strong correlation was observed between the Japanese SOS-PD IWS component and NRSobs (r = 0.91, p < 0.001). Inter-rater reliability was also robust, with a kappa coefficient of 0.95 and an ICC of 0.98. Conclusions: The Japanese version of the SOS-PD scale exhibits strong validity and inter-rater reliability for IWS assessment within Japanese PICUs. This validated instrument can support the early detection and appropriate management of pediatric IWS in Japan, with the potential to enhance the quality of patient care. Full article

Patients with chronic cholestatic liver diseases often experience itch and struggle with this symptom. We discuss the mechanism of itch in patients with chronic cholestatic liver diseases, such as primary biliary cholangitis (PBC) and others, and their therapies, including ileal bile acid transporter (IBAT) inhibitors. In patients with PBC, there are high serum/plasma concentrations of multiple factors, including bile salts, bilirubin, endogenous opioids, lysophosphatidic acid (LPA), autotaxin, and histamine. Bile salts, bilirubin, LPA, and autotaxin affect itch mediators in the skin and sensory nerves, while the endogenous opioid balance affects mediators in the spinal cord. Itch is sensitized by both the peripheral and central nervous systems. Both mechanisms are involved in itch in patients with chronic cholestatic liver disease. Although IBAT inhibitors have been approved for use in pediatric cholestatic conditions, such as progressive familial intrahepatic cholestasis and Alagille syndrome, IBAT inhibition seems to be a promising treatment for chronic refractory itch in patients with PBC. A traditional non-systematic review results in this narrative review. Multidisciplinary cooperation, involving hepatologists, dermatologists, and pharmacists, could provide better treatment for PBC patients suffering from refractory itch. In conclusion, we summarized the existing knowledge on itch caused by chronic cholestatic liver diseases, especially in PBC with a focus on the mechanisms and therapies. This narrative review provides the mechanisms and therapeutic options for itch in patients with chronic cholestatic liver diseases. Full article

Background/Objectives: Appropriate postoperative management, especially in pediatric patients, can be challenging for anesthesiologists. This retrospective study used machine learning to investigate the effects and complications of patient-controlled analgesia (PCA) in children undergoing orthopedic surgery. Methods: The medical records of children who underwent orthopedic surgery in a single tertiary hospital and received intravenous and epidural PCA were analyzed. Predictive models were developed using machine learning, and various demographic, anesthetic, and surgical factors were investigated to predict postoperative pain and complications associated with PCA. Results: Data from 1968 children were analyzed. Extreme gradient boosting effectively predicted moderate postoperative pain for the 6–24-h (area under curve (AUC): 0.85, accuracy (ACC): 0.79) and 24–48-h (AUC: 0.89, ACC: 0.87) periods after surgery. The factors that predicted moderate postoperative pain included the pain score immediately before the measurement period, the total amount of opioid infused, and age. For predicting side effects during the 6–24-h period after surgery, a least absolute shrinkage and selection operator model (AUC: 0.75, ACC: 0.64) was selected, while a random forest model (AUC: 0.91, ACC: 0.87) was chosen for the 24–48-h period post-surgery. The factors that predicted complications included the occurrence of side effects immediately before the measurement period, the total amount of opioid infused before the measurement period, and age. Conclusions: This retrospective study introduces machine-learning-based models and factors aimed at forecasting moderate postoperative pain and complications of PCA in children undergoing orthopedic surgery. This research has the potential to enhance postoperative pain management strategies for children. Full article

Regional anesthesia has gained increasing attention in pediatric surgery as a valuable tool for managing perioperative pain and improving surgical outcomes. This narrative review highlights the numerous advantages of regional anesthesia in pediatric populations, including superior pain control, reduced reliance on systemic opioids, fewer anesthetic-related complications, and enhanced recovery profiles. Using ultrasound-guided techniques has further expanded the safety and precision of regional blocks in children. Regional anesthesia also addresses critical concerns about the potential neurotoxicity of general anesthetics in developing brains, offering a safer alternative or complement for specific procedures. Reducing systemic anesthetic and opioid exposure minimizes the risk of adverse effects such as respiratory depression, nausea, and sedation, which are particularly significant in medically fragile or younger patients. Furthermore, regional techniques contribute to faster recovery times, better preservation of neurophysiological monitoring signals during surgery, and attenuation of the stress response. The integration of adjuvants like clonidine, dexmedetomidine, and dexamethasone further enhances the efficacy and duration of regional blocks while improving safety profiles. Despite these benefits, implementing regional anesthesia in pediatric populations requires specialized expertise and an understanding of children’s unique anatomical and physiological differences. This review underscores the growing role of regional anesthesia in modern pediatric perioperative care. It highlights its potential to optimize outcomes, reduce complications, and address emerging concerns about the safety of general anesthesia in children undergoing surgery. Full article

Neuropathic pain (NP) is a common complication associated with some types of childhood cancer, mainly due to nerve compression, chronic post-surgical pain, chemotherapy, and radiotherapy. NP is usually less responsive to traditional analgesics, and there is generally a lack of evidence on its management in cancer patients, leading to recommendations often based on clinical trials conducted on other forms of non-malignant NP. In pediatric oncology, managing NP is still very challenging for physicians. Different factors contribute to increasing the risk of undertreatment: (a) children may be unable to describe the quality of pain; therefore, the risk for NP to be underestimated or remain unrecognized; (b) specific tools to diagnose NP have not been validated in children; (c) there is a lack of randomized clinical trials involving children, with most evidence being based on case series and case reports; (d) most drugs used for adult patients are not approved for childhood cancers, and drug regulation varies among different countries; (e) recommendations for pediatric pain treatment are still not available. In this paper, a multidisciplinary team will review the current literature regarding children with cancer-related NP to define the best possible diagnostic strategies (e.g., clinical and instrumental tests) and propose a therapeutic care pathway, including both non-pharmacological and pharmacological approaches, which could help pediatricians, oncologists, neurologists, and pain therapists in designing the most effective multidisciplinary approach.

Background: While multimodal analgesia is the standard of care for postoperative pain relief, opioid medications continue to be a part of the treatment regimen, especially for more invasive surgeries such as spinal fusion, craniofacial reconstruction, laparotomy, and others. In pediatric patients, safe usage, storage, and dosing are especially important, along with clear instructions to caregivers on how to manage their child’s pain. Combination opioids such as hydrocodone with acetaminophen and acetaminophen with codeine are the most commonly prescribed opioid medications for postoperative pain control. However, these combination products can lead to acetaminophen toxicity, limit the ability to prescribe acetaminophen or ibuprofen, and add to caregiver confusion. Administering acetaminophen and ibuprofen individually rather than in combination products allows the maximal dosing of these nonopioid medications. The primary aim of this quality improvement (QI) project was to increase the utilization of single-agent opioids for postoperative pain control, primarily oxycodone, by the various surgical groups here at Cook Children’s Medical Center (CCMC). Methods: The project setting was a tertiary-level children’s hospital with a level 2 trauma center, performing over 20,000 surgeries annually. The opioid stewardship committee (OSC) mapped the steps and overlapping activities in the intervention that led to changes in providers’ prescription practices. A Plan–Do–Study–Act continuous improvement cycle allowed for an assessment and modification of implementation strategies. Statistical control process charts were used to detect the average percentage change in surgical specialties using single-agent opioid therapy. Data were monitored for three periods: one-year pre-intervention, one-year post-intervention, and one-year sustainment periods. Results: There were 4885 (41%) pre-intervention procedures, 3973 (33%) post-intervention procedures, and 3180 (26%) sustainment period procedures that received opioids. During the pre-intervention period, the average proportion of single-agent opioids prescribed was 8%. This average shifted to 89% for the first five months of the post-intervention period, then to 91% for the remainder of the study. Conclusions: The methodical application of process improvement strategies can result in a sustained change from outpatient post-surgical combination opioid prescriptions to single-agent opioid prescriptions in multiple surgical departments.

Background/Objectives: Prescription opioid use before adulthood is typically effective for acute pain control and is also associated with adverse short- and long-term consequences. Methods: This study examined pediatric opioid prescribing trends over time across different age groups (early childhood, school age, adolescence, young adult) and sociodemographic subgroups (sex, ethnicity, race, language, payer type) from 2005 to 2016. Results: Utilizing 42,020 first outpatient opioid prescriptions for youth aged 0–21 years from a large US children’s hospital, this research found notable trends and disparities. Prescription rates increased by 35% from 2005–2007 to 2008–2010, then decreased by 14% from 2008–2010 to 2011–2013, and decreased again by 22% from 2011–2013 to 2014–2016. Chi-squared tests indicated significant changes in prescription rates across all sociodemographic subgroups, though only age group, ethnicity, and payer type (i.e., the party responsible for payment for hospital services) had changes with non-negligible effect sizes (Cramer’s V). Specifically, age group showed small to medium effects (V = 0.16), while ethnicity and payer demonstrated small effects (V = 0.10 each). This study highlights variations in opioid prescribing trends, particularly among different age groups, ethnicities, and payer statuses up to 2016. Conclusions: These findings reveal differing trends in pediatric opioid prescribing during the peak of the opioid epidemic, highlighting the importance of considering age and sociodemographic variables for understanding prescribing patterns fully and raising potential concerns about inequities in pain management. Future studies should explore similar trends from 2016 onward. Full article

Pediatric regional anesthesia is evolving with new peripheral nerve blocks and techniques aimed at improving perioperative pain management. While caudal blocks have long been standard due to their simplicity and low complication rates, newer fascial plane blocks offer comparable efficacy with enhanced nerve coverage tailored to specific surgeries. Moreover, adjuncts like dexmedetomidine and dexamethasone have shown promise in prolonging block duration and enhancing post-operative pain relief and patient satisfaction. The integration of these advancements into clinical practice has yielded significant benefits, including reduced intraoperative fluid requirements, decreased reliance on opioids postoperatively, earlier initiation of enteral nutrition, lower readmission rates, shorter hospital stays, and decreased overall hospital costs. Our review underscores the technical progress and expanding literature supporting the rapid adoption of these impactful regional anesthesia techniques in pediatric care. Full article

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. Full article

Fentanyl is an opioid with powerful analgesic effects and a high speed of action. Due to its pharmacological properties, this molecule has therapeutic application as an anesthetic in surgery or as palliative therapy for cancer patients. Unfortunately, in recent years, the easy availability of this substance, the low cost and the illegal online market have favored the large-scale diffusion of fentanyl. Fentanyl is available in different forms, including nasal spray, oral patches, soluble capsules, aerosol or the new version of fentanyl mixed with other drugs, making its use very widespread. Subjects of various ages are involved in fentanyl consumption, including minors that have not yet reached adolescence. In this work, we performed a literature review using the search engines PubMed NCBI and SCOPUS regarding episodes of acute fentanyl intoxication occurring in those of a pediatric age using the Mesh Terms “fentanyl” AND “overdose” AND “children”. The inclusion criteria were English papers published in the last 10 years regarding the cases of children under the age of 10. We evaluated the most frequent methods of intake and the circumstances of such episodes. In cases of death, we analyzed the autopsy, the toxicological findings and the investigations carried out. The review results show that in this age group (under < 10 y.o. s), it is possible to identify the risk factors for fentanyl intake, such as the presence of this molecule within the family unit due to drug addiction or medical therapy. The results also demonstrate a significant risk of underestimation of this phenomenon, since the molecule is often not investigated through adequate toxicological analysis. These results, therefore, suggest always carrying out toxicological investigations in the case of suspected fentanyl intoxication, both on patients or cadavers. The investigations must always include a urinary screening for opiates, and the request for a second level analysis with molecule dosage in cases of positivity or in cases of strong suspicion for assumption. In cases of intoxication in a family context of drug addiction, it is necessary to investigate the chronicity of the intake through hair analysis and evaluate the possible co-administration of other drugs. In conclusion, we suggest a protocol, applicable both on patients or cadavers, which can be useful for physicians and forensic pathologists in order to promptly identify these cases and allow for the reporting of them to the judicial authorities with the adoption of strict prevention and control measures.

Background/Objectives: Preoperative fasting guidelines traditionally aim to reduce pulmonary aspiration risk. However, concerns over the adverse effects of prolonged fasting have led to exploring alternatives. This study aimed to investigate the impact of preoperative clear liquid intake on postoperative outcomes in children undergoing minimally invasive repair of pectus excavatum (MIRPE). Methods: A prospective randomized controlled study was conducted on children aged 3–6 years scheduled for elective MIRPE. Patients were randomized into either a routine overnight fasting group (NPO) or a clear liquid group. The incidence and severity of emergence delirium (ED) were assessed using Pediatric Anesthesia Emergence Delirium (PAED) and Watcha scales at recovery room. Postoperative pain scores and opioid requirements were evaluated at intervals of 1–6 h, 6–12 h, and 12–24 h after surgery. Results: Fasting time was 178.6 ± 149.5 min and 608.9 ± 148.4 min in the clear liquid group compared and NPO group, respectively. The incidence of ED, measured by PAED and Watcha scales, was lower in the clear liquid group (PAED score ≥ 12: 55.6% vs. 85.2%, p = 0.037; Watcha score ≥ 3: 51.9% vs. 85.2%, p = 0.019). The highest PAED score recorded in the recovery room was significantly lower in the clear liquid group (11.4 ± 2.8 vs. 14.6 ± 2.8, p < 0.001). Clear liquid group showed significantly lower pain scores at 1–6, 6–12, and 12–24 h postoperatively. Additionally, clear liquid group had lower opioid requirement at 1–6 and 6–12 h postoperatively. Conclusions: Preoperative clear liquid consumption was associated with a lower incidence of ED in pediatric patients undergoing MIRPE. Full article

Background: Pediatric regional anesthesia has been driven by the gradual rise in the adoption of opioid-sparing strategies and the growing concern over the possible adverse effects of general anesthetics on neurodevelopment. Nonetheless, performing regional anesthesia studies in a pediatric population is challenging and accounts for the scarce evidence. This study aimed to review the scientific foundation of studies in cadavers to assess regional anesthesia techniques in children. Methods: We searched the following databases MEDLINE, EMBASE, and Web of Science. We included anatomical cadaver studies assessing peripheral nerve blocks in children. The core data collected from studies were included in tables and comprised block type, block evaluation, results, and conclusion. Results: The search identified 2409 studies, of which, 16 were anatomical studies on the pediatric population. The techniques evaluated were the erector spinae plane block, ilioinguinal/iliohypogastric nerve block, sciatic nerve block, maxillary nerve block, paravertebral block, femoral nerve block, radial nerve block, greater occipital nerve block, infraclavicular brachial plexus block, and infraorbital nerve block. Conclusion: Regional anesthesia techniques are commonly performed in children, but the lack of anatomical studies may result in reservations regarding the dispersion and absorption of local anesthetics. Further anatomical research on pediatric regional anesthesia may guide the practice. Full article
