Randomized trial of acupuncture with antiemetics for reducing postoperative nausea in children.

BACKGROUND: Postoperative nausea and vomiting (PONV) is common after tonsillectomy in children. There is evidence that perioperative acupuncture at the pericardium 6 (P6) point is effective for preventing PONV in adults. Our goal was to determine if intraoperative acupuncture at the P6 point, in addition to usual antiemetics, is more effective than antiemetics alone in preventing PONV in children. METHODS: In a randomized double-blind trial, 161 children age 3 through 9 years undergoing tonsillectomy with or without adenoidectomy were randomized to either bilateral acupuncture at P6 plus antiemetics (n = 86) or antiemetics only (n = 75). All participants received ondansetron 0.15 mg/kg and dexamethasone 0.25 mg/kg, up to 10 mg. The presence of nausea, retching, emesis and administration of additional antiemetics were recorded during phases I and II of PACU recovery. Follow-up calls occurred on postoperative day 1 (POD 1). RESULT: During phase I and II recovery, the incidence of PONV was significantly less with acupuncture than without (7.0% vs 34.7%, RR: 0.2, 95% CI: 0.09-0.46; P < 0.001). The difference in PONV was driven by less nausea in the acupuncture group (5.0% vs 24.0%), with no difference in vomiting between the two groups. In the first 24 hours, PONV occurred in 36.1% with acupuncture and 49.3% without; these values did not differ significantly (P = 0.09). CONCLUSIONS: Children receiving acupuncture plus antiemetic therapy had less risk of developing nausea during phase I and II recovery, but there was no difference in PONV on POD 1. Acupuncture may reduce nausea in the PACU, even when combined with antiemetics.

Feed and Swaddle: An Alternative to Infant Sedation for Craniofacial Imaging.

OBJECTIVE: The gold standard for diagnosis of craniosynostosis is a clinical examination and motionless head computed tomography (CT). Computed tomography sedation is associated with increased cost, resource utilization, medical, and possible developmental risks. This study investigates whether a "feed and swaddle" protocol can be used to achieve diagnostic quality craniofacial imaging without the use of infant sedation. DESIGN: Prospective cohort study. SETTING: Tertiary academic medical center. PATIENTS: Ninety patients <18 months of age undergoing evaluation for craniosynostosis from 2012 to 2018. INTERVENTIONS: A feed and swaddle protocol. MAIN OUTCOME MEASURES: Diagnostic level imaging without the use of infant sedation. RESULTS: Eighty-five (94%) achieved a diagnostic quality craniofacial CT scan using the "feed and swaddle" method. Mean patient age was 24.0 ± 10.0 weeks. Craniosynostosis was diagnosed in 74% of patients. Mean age of patients with successful completion of a CT scan was 23.7 ± 9.6 weeks, compared to 27.2 ± 17.1 weeks for unsuccessful completion. Mean weight for the successful group was 15.6 ± 2.9 pounds and 15.9 ± 2.5 pounds for the unsuccessful group. Mean travel distance was 59.2 ± 66.5 miles for successful patients and 66.5 ± 61.5 miles for unsuccessful patients. For the unsuccessful patients, there were no delays in surgical planning or scheduling. CONCLUSION: The "feed and swaddle" protocol described here is an effective alternative to infant sedation for motionless craniofacial CT imaging.

Endoscopic Versus Open Repair for Craniosynostosis in Infants Using Propensity Score Matching to Compare Outcomes: A Multicenter Study from the Pediatric Craniofacial Collaborative Group.

BACKGROUND: The North American Pediatric Craniofacial Collaborative Group (PCCG) established the Pediatric Craniofacial Surgery Perioperative Registry to evaluate outcomes in infants and children undergoing craniosynostosis repair. The goal of this multicenter study was to utilize this registry to assess differences in blood utilization, intensive care unit (ICU) utilization, duration of hospitalization, and perioperative complications between endoscopic-assisted (ESC) and open repair in infants with craniosynostosis. We hypothesized that advantages of ESC from single-center studies would be validated based on combined data from a large multicenter registry. METHODS: Thirty-one institutions contributed data from June 2012 to September 2015. We analyzed 1382 infants younger than 12 months undergoing open (anterior and/or posterior cranial vault reconstruction, modified-Pi procedure, or strip craniectomy) or endoscopic craniectomy. The primary outcomes included transfusion data, ICU utilization, hospital length of stay, and perioperative complications; secondary outcomes included anesthesia and surgical duration. Comparison of unmatched groups (ESC: N = 311, open repair: N = 1071) and propensity score 2:1 matched groups (ESC: N = 311, open repair: N = 622) were performed by conditional logistic regression analysis. RESULTS: Imbalances in baseline age and weight are inherent due to surgical selection criteria for ESC. Quality of propensity score matching in balancing age and weight between ESC and open groups was assessed by quintiles of the propensity scores. Analysis of matched groups confirmed significantly reduced utilization of blood (26% vs 81%, P < .001) and coagulation (3% vs 16%, P < .001) products in the ESC group compared to the open group. Median blood donor exposure (0 vs 1), anesthesia (168 vs 248 minutes) and surgical duration (70 vs 130 minutes), days in ICU (0 vs 2), and hospital length of stay (2 vs 4) were all significantly lower in the ESC group (all P < .001). Median volume of red blood cell administered was significantly lower in ESC (19.6 vs 26.9 mL/kg, P = .035), with a difference of approximately 7 mL/kg less for the ESC (95% confidence interval for the difference, 3-12 mL/kg), whereas the median volume of coagulation products was not significantly different between the 2 groups (21.2 vs 24.6 mL/kg, P = .73). Incidence of complications including hypotension requiring treatment with vasoactive agents (3% vs 4%), venous air embolism (1%), and hypothermia, defined as <35°C (22% vs 26%), was similar between the 2 groups, whereas postoperative intubation was significantly higher in the open group (2% vs 10%, P < .001). CONCLUSIONS: This multicenter study of ESC versus open craniosynostosis repair represents the largest comparison to date. It demonstrates striking advantages of ESC for young infants that may result in improved clinical outcomes, as well as increased safety.

A prospective study comparing perioperative anxiety and posthospital behavior in children with autism spectrum disorder vs typically developing children undergoing outpatient surgery.

BACKGROUND: Research describing the experience of youth with autism spectrum disorders in the perioperative setting is limited. This study compared youth with autism spectrum disorder to typically developing children in the perioperative setting and examined group differences in: child anxiety, parent anxiety, premedication patterns, induction compliance, and changes in behavior postprocedure. METHODS: Participants were 60 youth (32 with autism spectrum disorder, 28 typically developing) of ages 2-19 years undergoing outpatient surgery and their parents. Parents and research assistants rated children's anxiety at 3 time points (waiting room, preoperative holding, separation), and parents rated their own anxiety in the waiting room and at separation. The anesthesiologist rated induction compliance. Postprocedure behavior change was assessed via phone survey 1 and 7 days postprocedure. Analyses examined group differences in anxiety, medication patterns, and behavior. RESULTS: Children with autism spectrum disorder had higher research assistant reported anxiety than typically developing youth in the holding room only. There were no group differences in parent report of their own anxiety or their child's anxiety across time points. Compared to typically developing youth, children with autism spectrum disorder were more likely to receive a premedication (including nonstandard premedication), and had poorer induction compliance. Groups did not differ on posthospital behavior change 1 or 7 days postsurgery. CONCLUSION: Findings revealed ratings of anxiety in youth with and without autism spectrum disorder facing surgery varied by reporter and setting, highlighting the importance of using multiple reporters in research of youth with autism spectrum disorder in the perioperative period. Furthermore, while results showed group differences in premedication patterns and induction compliance, groups did not differ in level of negative behavior change after surgery. Future research can examine how individual differences in youth with autism impact anxiety in the perioperative setting and degree of behavior change postprocedure.

Perioperative Outcomes and Management in Pediatric Complex Cranial Vault Reconstruction: A Multicenter Study from the Pediatric Craniofacial Collaborative Group.

BACKGROUND: The Pediatric Craniofacial Collaborative Group established the Pediatric Craniofacial Surgery Perioperative Registry to elucidate practices and outcomes in children with craniosynostosis undergoing complex cranial vault reconstruction and inform quality improvement efforts. The aim of this study is to determine perioperative management, outcomes, and complications in children undergoing complex cranial vault reconstruction across North America and to delineate salient features of current practices. METHODS: Thirty-one institutions contributed data from June 2012 to September 2015. Data extracted included demographics, perioperative management, length of stay, laboratory results, and blood management techniques employed. Complications and outlier events were described. Outcomes analyzed included total blood donor exposures, intraoperative and perioperative transfusion volumes, and length of stay outcomes. RESULTS: One thousand two hundred twenty-three cases were analyzed: 935 children aged less than or equal to 24 months and 288 children aged more than 24 months. Ninety-five percent of children aged less than or equal to 24 months and 79% of children aged more than 24 months received at least one transfusion. There were no deaths. Notable complications included cardiac arrest, postoperative seizures, unplanned postoperative mechanical ventilation, large-volume transfusion, and unplanned second surgeries. Utilization of blood conservation techniques was highly variable. CONCLUSIONS: The authors present a comprehensive description of perioperative management, outcomes, and complications from a large group of North American children undergoing complex cranial vault reconstruction. Transfusion remains the rule for the vast majority of patients. The occurrence of numerous significant complications together with large variability in perioperative management and outcomes suggest targets for improvement.

Implementation of a Tranexamic Acid Protocol to Reduce Blood Loss During Cranial Vault Remodeling for Craniosynostosis.

OBJECTIVE: Pediatric cranial vault remodeling for repair of craniosynostosis is associated with significant blood loss and transfusion requirements. Beginning in 2011, the authors evaluated the impact tranexamic acid (TXA) on blood loss and blood product transfusion for children less than 15 months of age undergoing primary surgical repair of nonsyndromic single suture craniosynostosis. METHODS: Following institutional review board approval, the authors performed a retrospective study of all children undergoing surgical correction of craniosynostosis at Oregon Health & Science University from 2005 to 2015. All available records were reviewed, and patient data were collected from the time of preoperative evaluation until discharge, comparing patient and clinical variables before and after the implementation of perioperative TXA. RESULTS: Of a total of 259 patients with craniosynostosis, 187 had nonsyndromic single-suture involvement; 69 of these patients (36.9%) received TXA. A single surgical team (AAK and NRS) performed all operations. Median age at the time of surgery was 8.1 months (interquartile range [IQR] of 6.0-9.8 months). The TXA group had a significant reduction in estimated intraoperative blood loss (26 mL/kg versus 36 mL/kg, P <0.001), cell saver volume transfused 6 mL/kg versus 10 mL/kg, P <0.001), red cell transfusion volume (32 mL/kg versus 42 mL/kg, P <0.001), exposure to plasma transfusion (0% versus 24% P <0.001), exposure to cryoprecipitate transfusion (0% versus 16%, P <0.001), and exposure to platelet transfusion (0% versus 7.6% P = 0.03). Despite reduced red cell transfusion, the TXA-treated patients exhibited similar postoperative hematocrits (30.4 versus 30.3 P = 0.906) to those not treated with TXA. Use of TXA was associated with reduced length of stay (4 days IQR 3-4 versus 4 days IQR 4-5, P <0.001) and reduced postoperative output from surgically placed drains (181 mL versus 311 mL P <0.001). There was no difference in postoperative complications between groups and no deaths in either group. CONCLUSIONS: The introduction of TXA for nonsyndromic single-suture synostosis repair at our institution has significantly reduced blood loss and blood product and plasma transfusion during and following primary cranial vault remodeling for single suture craniosynostosis. Postoperative hematocrit was similar in the TXA-treated and untreated groups despite reduced red cell transfusion in the treated group. In addition, TXA use in this population has eliminated the need for plasma transfusion, and is associated with a shorter hospital stay. No difference in postoperative complications was observed. Our data provide support for further investigation of TXA treatment to improve clinical outcomes in children undergoing pediatric cranial vault remodeling.

Autistic children and anesthesia: is their perioperative experience different?

BACKGROUND: Children with autism spectrum disorders (ASD) are an increasingly common patient population in the perioperative setting. Children with ASD present with abnormal development in social interaction, communication, and stereotyped patterns of behavior and may be more prone to elevated perioperative anxiety. The perioperative experience for these patients is complex and presents a unique challenge for clinicians. AIM: The aim of the current study was to provide a further understanding of the premedication patterns and perioperative experiences of children with ASD in comparison to children without ASD. METHODS: Using a retrospective cohort study design, medical records were evaluated for patients with and without ASD undergoing general anesthesia for dental rehabilitation from 2006-2011. The following objectives were measured and compared: (i) premedication patterns and (ii) complications, pain, anesthetic type, PACU time, and time to discharge. To compare categorical variables, the chi-square test was used. Bivariate and multivariable analyses were performed to control for potential confounding as a result of baseline differences between the two groups. RESULTS: A total of 121 ASD patients and 881 non-ASD patients were identified. When controlling for age, weight, and gender, children in the ASD group were more likely to have nonstandard premedication types (P < 0.0001), while children without ASD were more likely to have standard premedication types (P < 0.0001). No significant group differences were identified in regards to the other outcome measures. CONCLUSIONS: Other than a significant difference in the premedication type and route, we found that children with ASD seemed to have similar perioperative experiences as non-ASD subjects. It was especially interesting to find that their postoperative period did not pose any special challenges. There is much to be learned about this unique patient population, and a more in-depth prospective evaluation is warranted to help better delineate the best approach to caring for these patients.

Temporal variation of the leak pressure of uncuffed endotracheal tubes following pediatric intubation: an observational study.

PURPOSE: Uncuffed endotracheal tubes are still preferred over cuffed tubes in certain situations in pediatric anesthesia. Inaccurately sized uncuffed endotracheal tubes may lead to inadequate ventilation or tracheal mucosal damage during anesthesia. Endotracheal tube size in children is usually assessed by measuring the audible leak pressure; if the fit of the tube and the leak pressure decrease significantly with time, reintubation during surgery as a result of inability to ventilate effectively may be challenging, and could lead to patient morbidity. There is no evidence to indicate whether leak pressure increases or decreases with time following endotracheal intubation with uncuffed tubes in children. METHODS: We measured leak pressure for 30 min following tracheal intubation in 46 ASA I children age 0-7 years after excluding factors known to modify leak pressure. RESULTS: The largest mean change in leak pressure occurred between time points 0 and 15 min, an increase of 3.5 cmH2O. Endotracheal tube size and type of procedure were associated with the leak pressure. In the final linear mixed model, there were no statistically significant variations in leak pressure over time (P = 0.129) in this group of children. CONCLUSIONS: We did not identify a consistent change in leak pressure within 30 min following tracheal intubation with uncuffed endotracheal tubes in this group of children.

A Systematic Scoping Review on Pedagogical Strategies of Interprofessional Communication for Physicians in Emergency Medicine.

BACKGROUND: Interprofessional communication (IPC) is integral to interprofessional teams working in the emergency medicine (EM) setting. Yet, the coronavirus disease 2019 pandemic has laid bare gaps in IPC knowledge, skills and attitudes. These experiences underscore the need to review how IPC is taught in EM. PURPOSE: A systematic scoping review is proposed to scrutinize accounts of IPC programs in EM. METHODS: Krishna's Systematic Evidence-Based Approach (SEBA) is adopted to guide this systematic scoping review. Independent searches of ninedatabases (PubMed, Embase, CINAHL, Scopus, PsycINFO, ERIC, JSTOR, Google Scholar and OpenGrey) and "negotiated consensual validation" were used to identify articles published between January 1, 2000 and December 31, 2020. Three research teams reviewed the data using concurrent content and thematic analysis and independently summarized the included articles. The findings were scrutinized using SEBA's jigsaw perspective and funneling approach to provide a more holistic picture of the data. IN TOTAL: 18,809 titles and abstracts were identified after removal of duplicates, 76 full-text articles reviewed, and 19 full-text articles were analyzed. In total, four themes and categories were identified, namely: (a) indications and outcomes, (2) curriculum and assessment methods, (3) barriers, and (4) enablers. CONCLUSION: IPC training in EM should be longitudinal, competency- and stage-based, underlining the need for effective oversight by the host organization. It also suggests a role for portfolios and the importance of continuing support for physicians in EM as they hone their IPC skills. HIGHLIGHTS: • IPC training in EM is competency-based and organized around stages.• IPC competencies build on prevailing knowledge and skills.• Longitudinal support and holistic oversight necessitates a central role for the host organization.• Longitudinal, robust, and adaptable assessment tools in the EM setting are necessary and may be supplemented by portfolio use.

Postnatal Expansion, Maturation, and Functionality of MR1T Cells in Humans.

MR1-restricted T (MR1T) cells are defined by their recognition of metabolite antigens presented by the monomorphic MHC class 1-related molecule, MR1, the most highly conserved MHC class I related molecule in mammalian species. Mucosal-associated invariant T (MAIT) cells are the predominant subset of MR1T cells expressing an invariant TCR α-chain, TRAV1-2. These cells comprise a T cell subset that recognizes and mediates host immune responses to a broad array of microbial pathogens, including Mycobacterium tuberculosis. Here, we sought to characterize development of circulating human MR1T cells as defined by MR1-5-OP-RU tetramer labeling and of the TRAV1-2+ MAIT cells defined by expression of TRAV1-2 and high expression of CD26 and CD161 (TRAV1-2+CD161++CD26++ cells). We analyzed postnatal expansion, maturation, and functionality of peripheral blood MR1-5-OP-RU tetramer+ MR1T cells in cohorts from three different geographic settings with different tuberculosis (TB) vaccination practices, levels of exposure to and infection with M. tuberculosis. Early after birth, frequencies of MR1-5-OP-RU tetramer+ MR1T cells increased rapidly by several fold. This coincided with the transition from a predominantly CD4+ and TRAV1-2- population in neonates, to a predominantly TRAV1-2+CD161++CD26++ CD8+ population. We also observed that tetramer+ MR1T cells that expressed TNF upon mycobacterial stimulation were very low in neonates, but increased ~10-fold in the first year of life. These functional MR1T cells in all age groups were MR1-5-OP-RU tetramer+TRAV1-2+ and highly expressed CD161 and CD26, markers that appeared to signal phenotypic and functional maturation of this cell subset. This age-associated maturation was also marked by the loss of naïve T cell markers on tetramer+ TRAV1-2+ MR1T cells more rapidly than tetramer+TRAV1-2- MR1T cells and non-MR1T cells. These data suggest that neonates have infrequent populations of MR1T cells with diverse phenotypic attributes; and that exposure to the environment rapidly and preferentially expands the MR1-5-OP-RU tetramer+TRAV1-2+ population of MR1T cells, which becomes the predominant population of functional MR1T cells early during childhood.

Intraoperative opioid dosing in children with and without cerebral palsy.

OBJECTIVE: To describe the differences in intraoperative opioid dosing and associated outcomes in children with and without cerebral palsy (CP). BACKGROUND: Previous work on children with cognitive impairment has suggested that they receive less intraoperative opioid than children without cognitive impairment. This finding may be due to a common concern that impaired children are hypersensitive to the adverse effects of opioids. Patterns in intraoperative opioid dosing have yet to be studied in children with motor impairment (e.g. CP). METHODS: We examined the medical records of pediatric patients with CP who underwent orthopedic surgery over the last decade at our institution, as well as the records of a randomly selected group of pediatric orthopedic patients without CP (non-CP). Outcome variables were intraoperative opioid dosing, postoperative intensive care unit (ICU) admission, and postoperative oxygen desaturation. We collected demographic, surgical, and medical data for covariate analysis. A stepwise multivariate regression was used for each outcome. RESULTS: Seventy-one (71) CP and 77 non-CP charts were included in the study. CP children received significantly less intraoperative opioid (3.26 +/- 3.01 microg.kg(-1) fentanyl dose equivalents) than non-CP children (4.58 +/- 3.79 microg.kg(-1)) (P = 0.02), and this difference was corroborated by the regression analysis, which significantly associated CP with decreased opioid dosing (P < 0.001). In addition, intraoperative opioid dosing, but not CP, predicted ICU admission (odds ratio: 1.463, 95% CI: 1.042-2.054, P = 0.03) and postoperative oxygen desaturation (odds ratio: 1.174, 95% CI: 1.031-1.338, P = 0.02). CONCLUSIONS: Similar to prior research on children with cognitive impairment, a reduction in intraoperative opioid dosing was found in children with CP. Given the discrepant doses of intraoperative opioid between groups, it is unclear whether children with CP are at any greater risk for untoward opioid-related events.

Objective and subjective assessment of sleep in adolescents with chronic pain compared to healthy adolescents.

OBJECTIVES: The purpose of this study was to compare sleep of adolescents with chronic pain and healthy adolescents using both subjective and objective sleep assessments, and to identify correlates of poor sleep. METHODS: Forty adolescents (n=20 with chronic pain and n=20 healthy adolescents), aged 12 to 17 years (72.5% female) participated. Adolescents completed self-report measures of pain, sleep quality and hygiene, presleep arousal/worry, and depressive symptoms. Sleep patterns were assessed over 7 consecutive days using an actigraph, a motion-monitoring device detecting sleep-wake patterns by measuring activity levels. Total sleep time, sleep efficiency, wake time, and wake bouts were derived from the actigraph and aggregated for analysis. RESULTS: Compared with healthy peers, adolescents with chronic pain demonstrated similar total sleep time as healthy adolescents, but significantly poorer sleep. In particular, adolescents with chronic pain subjectively reported poorer sleep quality and increased insomnia symptoms, and demonstrated lower actigraphic sleep efficiency and more wake bouts compared with their healthy peers. Depressive symptoms and worry at bedtime were significant predictors of subjectively reported sleep quality but not of actigraphic sleep. DISCUSSION: Adolescents with chronic pain evidenced poorer sleep quality, increased insomnia symptoms, and less efficient sleep with more wake bouts in comparison with healthy adolescents, findings that require replication in a larger sample. Assessment and management of sleep disturbances is an important aspect of care for children and adolescents with chronic pain.

A comparison of laser-assisted drug delivery at two output energies for enhancing the delivery of topically applied LMX-4 cream prior to venipuncture.

BACKGROUND: Laser-assisted drug delivery (LAD) has the potential for facilitating topical anesthesia with reduced onset time. METHODS: In this randomized, double-blind, crossover study we compared the efficacy and adverse event profile of LAD for topical anesthesia before venipuncture using two output energies (2.0 and 3.5 J/cm2). RESULTS: Mean Visual Analog Scale pain scores were not statistically different (P = 0.57) between the low-energy (mean = 6.7) and high-energy (mean = 8.1) lasers. CONCLUSIONS: LAD at an energy of 2.0 J/cm2 (570 mJ) is as effective, with similar adverse events, as an energy of 3.5 J/cm2 (1000 mJ) in facilitating topical anesthesia.

A Narrative Review: Actigraphy as an Objective Assessment of Perioperative Sleep and Activity in Pediatric Patients.

Sleep is an important component of pediatric health and is crucial for cognitive development. Actigraphy is a validated, objective tool to capture sleep and movement data that is increasingly being used in the perioperative context. The aim of this review is to present recent pediatric studies that utilized actigraphy in the perioperative period, highlight gaps in the literature, and provide recommendations for future research. A literature search was completed using OVID and PubMed databases and articles were selected for inclusion based on relevance to the topic. The literature search resulted in 13 papers that utilized actigraphic measures. Results of the review demonstrated that actigraphy has been used to identify predictors and risk factors for poor postoperative sleep, examine associations among perioperative pain and sleep patterns, and assess activity and energy expenditure in both inpatient and outpatient settings. We propose expansion of actigraphy research to include assessment of sleep via actigraphy to: predict functional recovery in pediatric populations, to study postoperative sleep in high-risk pediatric patients, to test the efficacy of perioperative interventions, and to assess outcomes in special populations for which self-report data on sleep and activity is difficult to obtain.

Perioperative opioid administration in children with and without developmental delay undergoing outpatient dental surgery.

STUDY OBJECTIVE: Prior research has indicated that children with developmental delay (DD) experience qualitative and quantitative differences in health care (Boulet et al., 2009). In the perioperative setting, there is concern that children with DD may be more likely to experience postoperative complications including agitation and nausea/vomiting than typically developing patients (TDP). Differences in the administration and dosage of perioperative opioids may contribute to this, however, empirical investigations are lacking. The purpose of this research was to compare the experience of postoperative nausea/vomiting and agitation, as well as to examine perioperative opioid administration, among children with DD as compared to TDP. DESIGN: Retrospective original research. SETTING: Operating room, postanesthesia care unit. PATIENTS: 1145 patients (1-20.9years, ASA I-III, 23.9% with a history of DD) who had undergone outpatient dental surgery involving extraction/restorations under general anesthesia. MEASUREMENTS: Data was obtained and analyzed from the medical records of both DD and TDP across a five-year period. Data included the experience of agitation, nausea/vomiting, as well as perioperative medication administration. MAIN RESULTS: Postoperative agitation and nausea/vomiting did not differ significantly between the DD and TDP groups. Children with DD were significantly less likely to receive opioids during both the intra and postoperative period (χ2=10.02, p=0.001 and χ2=8.08, p=0.003, respectively). Further, higher dosage of intraoperative opioids was predictive of reduced administration of postoperative opioids among TDP; however, no significant association was observed between the dosage of intraoperative opioids and administration of postoperative opioids in the DD group. CONCLUSIONS: Children with DD experience similar rates of postoperative complications including nausea/vomiting and agitation as TDP. DD children were less likely to receive both intra and postoperative opioids than TDP. Importantly, while the dosage of intraoperative opioids was predictive of administration of postoperative opioids in the TDP group, this was not the case for the DD group. Clinical implications are discussed.

Effect of disease-related pain on the health-related quality of life of children and adolescents with cystic fibrosis.

OBJECTIVES: The authors' objective was to describe the effect of recurrent pain symptoms on the health-related quality of life (HRQOL) of children and adolescents with cystic fibrosis (CF). Frequent pain, independent of disease severity, was hypothesized to be associated with broad decrements in physical, psychological, and social functioning. METHODS: Forty-six children and adolescents (mean age 12.9 years; 52% female) completed the Cystic Fibrosis Questionnaire-Revised (CFQ-R) to assess their HRQOL and a retrospective pain interview to assess pain location, frequency, intensity, duration, and bother during a routine clinic visit. Forced expiratory volume in 1 second as percent of predicted (FEV1%) was recorded from medical charts to assess the children's disease severity. RESULTS: As hypothesized, pain symptoms were related to children's physical, emotional, and role functioning, CF-related symptoms, and overall perception of their health. Children with frequent pain had significantly reduced physical functioning, vitality, role limitations, and overall perceptions of their health, and increased eating disturbances, treatment burden, respiratory, and digestive symptoms compared with children with no pain or less frequent pain. After controlling for the effects of disease severity, pain frequency continued to predict children's HRQOL in each of these areas. DISCUSSION: Children with frequent CF-related pain experienced broad decrements in their HRQOL. These findings are similar to those found in other populations of children experiencing disease-related pain, suggesting a pervasive impact of pain on overall health and well-being. Future research is needed to evaluate treatments to reduce pain symptoms and improve HRQOL in children with cystic fibrosis.

Use of oxcarbazepine to treat a pediatric patient with resistant complex regional pain syndrome.

UNLABELLED: We describe a 12-year-old patient with severe, protracted complex regional pain syndrome type I. His pain did not respond to gabapentin, amitriptyline, physical therapy, opioids, or nonsteroidal drugs. Sympathetic or regional block was not attempted because of persistent bacteremia and severe local sepsis. His pain responded dramatically to the addition of oxcarbazepine, with rapid improvement in his symptoms and functional status. We suggest that oxcarbazepine might be a useful adjunct in the treatment of gabapentin-resistant complex regional pain syndrome type I in children and should be considered. PERSPECTIVE: Oxcarbazepine's antinociceptive effect is mediated via sodium channel inhibition in neuropathic models and by inhibition of substance P and prostaglandins in anti-inflammatory models. The efficacy of oxcarbazepine in this patient might be attributable to these mechanisms or possibly to synergism with either gabapentin or the anti-inflammatory effects produced by amitriptyline.

Assessment of acute and chronic pain symptoms in children with cystic fibrosis.

Pain is important to assess and treat in children with cystic fibrosis (CF), because pain symptoms may limit children's ability to participate in their CF-related care and may reduce their overall well-being and quality of life. The aims of this study were to: 1) assess acute and chronic pain symptoms as reported by children with CF, and 2) examine the relationship between pain symptoms and disease severity as measured by percentage of forced expired volume in 1 sec (FEV1%). Forty-six children completed a self-report questionnaire assessing characteristics of chronic disease-related pain (frequency, intensity, duration, associated emotional upset, and location of pain). Children also rated their pain intensity associated with common CF-related procedures. The primary locations of pain reported were the abdominal/pelvic region, chest, and head/neck. Forty-six percent of the sample described pain occurring at least once per week. Most children reported their pain intensity as mild and of short duration. However, a small subgroup of children reported longer-lasting and moderately intense pain. Children with chest pain were found to be particularly at risk for experiencing more functional limitations and a significantly lower FEV1% compared to children without chest pain. The majority of children reported that nonpharmacological therapies (e.g., medication, rest, or distracting activities) provided some pain relief. Disease-related pain is common for children and adolescents with CF, suggesting that pain assessment should be a routine part of their clinical care. Further research is clearly needed to better understand the sources of pain and how best to provide relief.

Analgesia following surgery in children with and without cognitive impairment.

Both children and adults with cognitive impairment (CI) have historically been excluded from research examining pain. This is unfortunate since patients with CI may be at higher risk for experiencing pain or having their pain undertreated due to the difficulty of pain assessment and communication. There are now several published reports about the general pain experience of both adult and pediatric patients with cognitive impairment. The purpose of this study was to compare the amount and type of pain medication administered in children with and without CI after surgery to ascertain if there were any differences in analgesic administration patterns between these two groups. One hundred and fifty-two children with borderline to profound CI and 138 non impaired (NI) children were recruited to participate. Analgesic administration data include type and amount of opioid, type of non-opioid medication, and prescribed discharge medications. Results of this study show that children with CI undergoing surgery received less opioid in the perioperative period than children without CI. However, children with CI received comparable amounts and types of analgesics in the postoperative period as children without CI.

Recognition and management of iatrogenically induced opioid dependence and withdrawal in children.

Opioids are often prescribed to children for pain relief related to procedures, acute injuries, and chronic conditions. Round-the-clock dosing of opioids can produce opioid dependence within 5 days. According to a 2001 Consensus Paper from the American Academy of Pain Medicine, American Pain Society, and American Society of Addiction Medicine, dependence is defined as "a state of adaptation that is manifested by a drug class specific withdrawal syndrome that can be produced by abrupt cessation, rapid dose reduction, decreasing blood level of the drug, and/or administration of an antagonist." Although the experience of many children undergoing iatrogenically induced withdrawal may be mild or goes unreported, there is currently no guidance for recognition or management of withdrawal for this population. Guidance on this subject is available only for adults and primarily for adults with substance use disorders. The guideline will summarize existing literature and provide readers with information currently not available in any single source specific for this vulnerable pediatric population.
