The eXpectations of Parents regarding Anesthesiology Study (XPAS) from a parental perspective: a two-phase observational cross-sectional cohort study.

BACKGROUND: Uncertainty concerning anesthetic procedures and risks in children requiring anesthesia may cause concerns in parents and caregivers. AIMS: To explore parental expectations and experiences regarding their child's anesthesia using questionnaires designed with parental input. METHODS: This observational cross-sectional cohort study included parents (including caregivers) of children undergoing anesthesia in a tertiary pediatric referral university hospital. The study consisted of two phases. In Phase 1, we developed three questionnaires with parental involvement through a focus group discussion and individual interviews. The questionnaires focused on parental satisfaction, knowledge, concerns, and need for preparation regarding their child's anesthesia. In Phase 2, independent samples of parents completed the questionnaires at three time points: before the preanesthesia assessment (T1), 2 days after the preanesthesia assessment (T2), and 4 days after the anesthetic procedure (T3). RESULTS: In Phase 1, 22 parents were involved in the development of the questionnaires. The three questionnaires contained 43 questions in total, of which 10 had been proposed by parents. In Phase 2, 78% (474 out of 934) parents participated at T1, 36% (610 out of 1705), at T2 and 34% (546 out of 1622) at T3. Parental satisfaction scores were rated on a visual analogue scale for the preanesthesia assessment with a median of 87/100, and with a median of 90/100 for the anesthetic procedure (0: not satisfied and 100: satisfied). Parental concerns were rated with a median of 50/100 (0: no concerns and 100: extremely concerned). Parental answers from the questionnaire at T2 revealed significant knowledge deficits, with only 73% reporting that the anesthesiologist was a physician. Parents preferred to receive more information about the procedure, especially regarding the intended effects and side effects of anesthesia. CONCLUSIONS: Overall, parental satisfaction scores regarding the pediatric anesthesiology procedure were high, with a minority expressing concerns. Parents indicated a preference for their child's anesthesiologist to visit them both before and after the anesthetic procedure. Parental expectations regarding anesthesia did not completely correspond with the information provided; more information from the clinician about the intended effects and side effects of anesthesia was desired.

Off-label use of dexmedetomidine in paediatric anaesthesiology: an international survey of 791 (paediatric) anaesthesiologists.

PURPOSE: The purpose of this international study was to investigate prescribing practices of dexmedetomidine by paediatric anaesthesiologists. METHODS: We performed an online survey on the prescription rate of dexmedetomidine, route of administration and dosage, adverse drug reactions, education on the drug and overall experience. Members of specialist paediatric anaesthesia societies of Europe (ESPA), New Zealand and Australia (SPANZA), Great Britain and Ireland (APAGBI) and the USA (SPA) were consulted. Responses were collected in July and August 2019. RESULTS: Data from 791 responders (17% of 5171 invitees) were included in the analyses. Dexmedetomidine was prescribed by 70% of the respondents (ESPA 53%; SPANZA 69%; APAGBI 34% and SPA 96%), mostly for procedural sedation (68%), premedication (46%) and/or ICU sedation (46%). Seventy-three percent had access to local or national protocols, although lack of education was the main reason cited by 26% of the respondents not to prescribe dexmedetomidine. The main difference in dexmedetomidine use concerned the age of patients (SPA primarily < 1 year, others primarily > 1 year). The dosage varied widely ranging from 0.2-5 µg kg-1 for nasal premedication, 0.2-8 µg kg-1 for nasal procedural sedation and 0-4 µg kg-1 intravenously as adjuvant for anaesthesia. Only ESPA members (61%) had noted an adverse drug reaction, namely bradycardia. CONCLUSION: The majority of anaesthesiologists use dexmedetomidine in paediatrics for premedication, procedural sedation, ICU sedation and anaesthesia, despite the off-label use and sparse evidence. The large intercontinental differences in prescribing dexmedetomidine call for consensus and worldwide education on the optimal use in paediatric practice.

Long-term neurodevelopment in children born with esophageal atresia: a systematic review.

BACKGROUND: Although the survival rate of esophageal atresia (EA) has increased to over 90%, the risk of functional long-term neurodevelopmental deficits is uncertain. Studies on long-term outcomes of children with EA show conflicting results. Therefore, we provide an overview of the current knowledge on the long-term neurodevelopmental outcome of children with EA. METHODS: We performed a structured literature search in Embase, Medline Ovid, Web of Science, Cochrane CENTRAL, and Google scholar on November 8, 2020 with the keywords 'esophageal atresia', 'long-term outcome', 'motor development', 'cognitive development', and 'neurodevelopment'. RESULTS: The initial search identified 945 studies, of which 15 were included. Five of these published outcomes of multiple tests or tested at multiple ages. Regarding infants, one of six studies found impaired neurodevelopment at 1 year of age. Regarding preschoolers, two of five studies found impaired neurodevelopment; the one study assessing cognitive development found normal cognitive outcome. Both studies on motor function reported impairment. Regarding school-agers, the one study on neurodevelopmental outcome reported impairment. Cognitive impairment was found in two out of four studies, and motor function was impaired in both studies studying motor function. CONCLUSIONS: Long-term neurodevelopment of children born with EA has been assessed with various instruments, with contrasting results. Impairments were mostly found in motor function, but also in cognitive performance. Generally, the long-term outcome of these children is reason for concern. Structured, multidisciplinary long-term follow-up programs for children born with EA would allow to timely detect neurodevelopmental impairments and to intervene, if necessary.

Associations of perioperative characteristics with motor function in preschool children born with esophageal atresia.

BACKGROUND: Children born with esophageal atresia experience long-term neurodevelopmental deficits, with unknown origin. AIMS: To find associations between perioperative variables during primary esophageal atresia repair and motor function at age 5 years. METHODS: This ambidirectional cohort study included children born with esophageal atresia who consecutively had been operated on in the Erasmus MC-Sophia Children's Hospital, University Medical Center, Rotterdam, from January 2007 through June 2013. The perioperative data of this cohort were collected retrospectively; the motor function data prospectively. RESULTS: After exclusion of patients with syndromal congenital diseases (n = 8) and lost to follow-up (n = 10), the data of 53 children were included. The mean (SD) total motor function impairment z-score at 5 years of age was -0.66 (0.99), significantly below normal (p < .001). In multivariable linear regression analysis, number of postoperative days endotracheal intubation (B = -0.211, 95% CI: -0.389 to -0.033, p = .021) was negatively associated with motor outcome, whereas high blood pressure (B = 0.022, 95% CI 0.001 to 0.042, p = .038) was positively associated. Preoperative nasal oxygen supplementation versus room air (B = 0.706, 95% CI: 0.132 to 1.280, p = .016) was positively associated with motor outcome, which we cannot explain. CONCLUSIONS: Motor function in 5-year-old esophageal atresia patients was impaired and negatively associated with the number of postoperative days of endotracheal intubation and positively associated with high blood pressure. Prospective studies with critical perioperative monitoring and monitoring during stay at the intensive care unit are recommended.

Towards integrative neuromonitoring of the surgical newborn: A systematic review.

BACKGROUND: The altered neurodevelopment of children operated on during the neonatal period might be due to peri-operative changes in the homeostasis of brain perfusion. Monitoring of vital signs is a standard of care, but it does not usually include monitoring of the brain. OBJECTIVES: To evaluate methods of monitoring the brain that might be of value. We also wanted to clarify if there are specific risk factors that result in peri-operative changes and how this might be evaluated. DESIGN: Systematic review. DATA SOURCES: A structured literature search was performed in MEDLINE in Ovid, Embase, Cochrane CENTRAL, Web of Science and Google Scholar. ELIGIBILITY CRITERIA: Studies in neonates who received peri-operative neuromonitoring were eligible for inclusion; studies on neurosurgical procedures or cardiac surgery with cardiopulmonary bypass and/or deep hypothermia cardiac arrest were excluded. RESULTS: Nineteen of the 24 included studies, totalling 374 infants, reported the use of near-infrared spectroscopy. Baseline values of cerebral oxygenation greatly varied (mean 53 to 91%) and consequently, no coherent results were found. Two studies found a correlation between cerebral oxygenation and mean arterial blood pressure. Five studies, with in total 388 infants, used (amplitude-integrated) electro-encephalography to study peri-operative brain activity. Overall, the brain activity decreased during anaesthesia and epileptic activity was more frequent in the peri-operative phase. The association between intra-operative cerebral saturation or activity and neuro-imaging abnormalities and/or neurodevelopmental outcome was investigated in six studies, but no association was found. CONCLUSION: Neuromonitoring with the techniques currently used will neither help our understanding of the altered neonatal pathophysiology, nor enable early detection of deviation from the norm. The modalities lack specificity and are not related to clinical (long-term) outcome or prognosis. Accordingly, we were unable to draw up a monitoring guideline.

A systematic review and narrative synthesis on the histological and neurobehavioral long-term effects of dexmedetomidine.

BACKGROUND: Recent experimental studies suggest that currently used anesthetics have neurotoxic effects on young animals. Clinical studies are increasingly publishing about the effects of anesthesia on the long-term outcome, providing contradictory results. The selective alpha-2 adrenergic receptor agonist dexmedetomidine has been suggested as an alternative nontoxic sedative agent. AIMS: The aim of this systematic review was to assess the potential neuroprotective and neurobehavioral effects of dexmedetomidine in young animals and children. METHODS: Systematic searches separately for preclinical and clinical studies were performed in Medline Ovid and Embase on February 14, 2018. RESULTS: The initial search found preclinical (n = 661) and clinical (n = 240) studies. A total of 20 preclinical studies were included. None of the clinical studies met the predefined eligibility criteria. Histologic injury by dexmedetomidine was evaluated in 11 studies, and was confirmed in three of these studies (caspase-3 activation or apoptosis). Decrease of injury caused by another anesthetic was evaluated in 16 studies and confirmed in 13 of these. Neurobehavioral tests were performed in seven out of the 20 studies. Of these seven rodent studies, three studies tested the effects of dexmedetomidine alone on neurobehavioral outcome in animals (younger than P21). All three studies found no negative effect of dexmedetomidine on the outcome. In six studies, outcome was evaluated when dexmedetomidine was administered following another anesthetic. Dexmedetomidine was found to lessen the negative effects of the anesthetic. CONCLUSION: In animals, dexmedetomidine was found not to induce histologic injury and to show a beneficial effect when administered with another anesthetic. No clinical results on the long-term effects in children have been identified yet.

Perioperative management of esophageal atresia/tracheo-esophageal fistula: An analysis of data of 101 consecutive patients.

BACKGROUND: The perioperative management of esophageal atresia/tracheo-esophageal fistula by open or thoracoscopic approach can be complicated by metabolic derangements. Little is known, however, about the severity of derangements of vital and metabolic parameters in the perioperative period. AIM: The aim of this study is to describe the perioperative courses of vital and metabolic parameters in 101 consecutive neonates undergoing surgical repair of esophageal atresia type C. METHOD: In a retrospective cohort study, we extracted all data from the electronic anesthetic and medical charts of patients who underwent esophageal atresia type C repair within 30 days of life (2007-2017). We distinguished three types of surgery: primary open, primary thoracoscopic, and primary thoracoscopic surgery converted to open surgery. Descriptive analysis was applied. RESULTS: The charts of 117 patients were reviewed: data of 101 were included. The perioperative anesthetic management was not standardized; various methods and medications were used for anesthesia induction and maintenance. Intraoperative blood gas analysis data of 72 patients were available and showed derangements regardless of type of surgery. The median pH-value decreased to 7.21 [IQR 7.14-7.30] and a pH-value below 7.20 was found in 29 patients; in four cases below 7.0, with the lowest value 6.83. The median PaCO2 reached an upper level of 7.5kPa [IQR 5.8-9.2]; in 13 cases above 10.0kPa, with a peak value of 25.8kPa. These high PaCO2 levels fluctuated with lowest measured PaCO2 of median 5.6 [IQR 4.5-6.6], with the lowest value 2.8kPa. The median PaO2 level reached an upper level of 16.9kPa [IQR 11.8-25.7], in 22 cases above 20.0kPa, with a peak value of 50.0kPa. These high levels fluctuated with lowest measured PaO2 levels of median 8.3kPa [IQR 6.73-10.5]; the lowest PaO2 value was 4.7 kPa. CONCLUSION: Open and thoracoscopic correction of esophageal atresia were associated with periods of severe metabolic derangements. These events need to be taken into account for the evaluation of esophageal atresia (surgical) care and in evaluations of short- and long-term outcomes.

Primary repair of esophageal atresia is followed by multiple diagnostic and surgical procedures.

BACKGROUND: Children born with esophageal atresia (EA) face comorbidities and complications often requiring surgery and anesthesia. We aimed to assess all procedures performed under general anesthesia during their first 12 years of life. METHODS: We performed a retrospective cohort study about subsequent surgeries and procedures requiring general anesthesia in children born with type C EA between January 2007 and December 2017, with follow-up to March 2019. RESULTS: Of 102 eligible patients, 63 were diagnosed with comorbidities, of whom 18 had VACTERL association. Follow-up time for all patients varied between 14 months and 12 years (median 7 years). The patients underwent total 637 procedures, median 4 [IQR2-7] per patient. In the first year of life, 464 procedures were performed, in the second year 69 and in the third year 29. Thirteen patients underwent no other procedures than primary EA repair. In 57 patients, 228 dilatations were performed. Other frequently performed procedures were esophagoscopy (n=52), urologic procedures (n=44) and abdominal procedures (n=33). CONCLUSIONS: Patients with EA frequently require multiple anesthetics for a variety of procedures related to the EA, complications and comorbidities. This study can help care providers when counselling parents of a patient with an EA by giving them more insight into possible procedures they can be confronted with during childhood.
