Procedural sedation and analgesia in pediatric diagnostic and interventional radiology: An expert DELPHI consensus document developed by the ITALIAN scientific society of anesthesia, analgesia, resuscitation and intensive care (SIAARTI).

BACKGROUND: Children undergoing diagnostic and interventional radiology procedures often require sedation to achieve immobility and analgesia if the procedure is painful. In the past decades, leading scientific organizations have developed evidence-based guidelines for procedural sedation and analgesia in children outside of the operating room. Their recommendations are being applied to procedural sedation in radiology. However, some questions remain open regarding specific aspects contextualized to the radiology setting, such as elective prone sedation, the urgency of the procedure, when venous access or airway protection is required, and others. AIMS: To address the unresolved issues of procedural sedation and analgesia in pediatric diagnostic and interventional radiology. METHODS: An expert panel of pediatricians, pediatric anesthesiologists, intensivists, and neuroradiologists selected topics representative of current controversies and formulated research questions. Statements were developed by reviewing the literature for new evidence, comparing expertise and experience, and expressing opinions. Panelists' agreement with the statements was collected anonymously using the DELPHI method. RESULTS: Twelve evidence-based or expert opinion incorporate are presented, considering risks, benefits, and applicability. CONCLUSIONS: This consensus document, developed by a multidisciplinary panel of experts involved in the field, provides statements to improve the quality of decision-making practice in procedural sedation and analgesia in pediatric radiology.

Pure Interstitial 7q21.3-q 31.1 Duplication: A Rare Segmental Genomic Aneuploidy: Case Report and Review of Cases with Distal and Similar Segment Involved.

In children with developmental delay (DD) and neurologic impairment, diagnosis can be challenging because of the wide spectrum of causes. Since the last decade, the use of array comparative genomic hybridization (CGH) offered a great contribution to get a diagnosis in complex phenotypes. The chromosome 7 is subject of interest in medical genetics because of its frequent association with chromosome aberrations, rearrangements, and deletions involving clinical manifestations. We hereby reported a 3-year-old male child patient with severe neuro-DD, craniofacial dysmorphisms, and pulmonary stenosis, whose array CGH analysis disclosed a duplication of 14.4 Mb on chromosome 7 (7q21.3-7q31.1). By reviewing the current literature to date, we first reported on neurologic and dysmorphic anomalies related to this rearrangement which was not previously reported.

Epidural analgesia during labour and stress markers in the newborn.

Labour and modes of delivery can influence the plasma levels of stress hormones and cytokines involved in pathophysiologic cascade, potentially damaging brain development of the newborn. This prospective observational, single-centre, case-control, non-profit study aimed to detect potential differences in foetal well-being such as stress neuroendocrine responses. Quantitative determinations of the stress markers interleukin (IL)-1ß, IL-8, and ß-endorphin were compared between the control group and the epidural analgesia group. We found higher IL1-ß levels but lower IL-8 and ß-endorphin levels in the epidural analgesia group than in the control group. No significant inter-group differences were observed for any parameters. Our findings demonstrate that epidural analgesia for pain relief during labour does not result in significant differences in blood stress response markers.IMPACT STATEMENTWhat is already known on this subject? We already know that plasma levels of stress hormones and cytokines are influenced by labour and delivery modes. This has a deep impact on the newborn in terms of brain damage, immune system deficits, and altered hypothalamic-pituitary axis responses. We also know that epidural analgesia is a widespread practice that offers pain relief to the woman in labour, but there are few studies on the potentially negative effects of epidural labour analgesia on the unborn child.What do the results of this study add? This study found no significative differences in blood stress response markers between the epidural analgesia group and the control group. Under this study circumstances we found out that epidural analgesia does not significantly influence the newborn's well-being during labour and delivery.What are the implications of these findings for clinical practice and/or further research? These findings must be confirmed by further studies to verify whether epidural analgesia is safe for the newborn's development.

Echocardiographic Parameters and Mortality in Pediatric Sepsis: A Systematic Review and Meta-Analysis.

OBJECTIVE: We conducted a systematic review and meta-analysis to investigate the prognostic value of echocardiographic parameters in pediatric septic patients. DATA SOURCES: MEDLINE, PubMed, and EMBASE (last update April 5, 2020). STUDY SELECTION: Observational studies of pediatric sepsis providing echocardiographic parameters in relation to mortality. DATA EXTRACTION: Echocardiography data were categorized as those describing left ventricular systolic or diastolic function, right ventricular function, and strain echocardiography parameters. Data from neonates and children were considered separately. Analysis is reported as standardized mean difference and 95% CI. DATA SYNTHESIS: We included data from 14 articles (n = 5 neonates, n = 9 children). The fractional shortening was the most commonly reported variable (11 studies, n = 555 patients) and we did not identify an association with mortality (standardized mean difference 0.22, 95% CI [-0.02 to 0.47]; p = 0.07, I2 = 28%). In addition, we did not find any association with mortality also for left ventricular ejection fraction (nine studies, n = 417; standardized mean difference 0.06, 95% CI [-0.27 to 0.40]; p = 0.72, I2 = 51%), peak velocity of systolic mitral annular motion determined by tissue Doppler imaging wave (four studies, n = 178; standardized mean difference -0.01, 95% CI [-0.34 to 0.33]; p = 0.97, I2 = 0%), and myocardial performance index (five studies, n = 219; standardized mean difference -0.51, 95% CI [-1.10 to 0.08]; p = 0.09, I2 = 63%). However, in regard to left ventricular diastolic function, there was an association with mortality for higher early wave of transmitral flow/peak velocity of early diastolic mitral annular motion determined by tissue Doppler imaging ratio (four studies, n = 189, standardized mean difference -0.45, 95% CI [-0.80 to -0.10]; p = 0.01, I2 = 0%) or lower peak velocity of early diastolic mitral annular motion determined by tissue Doppler imaging wave (three studies, n = 159; standardized mean difference 0.49, 95% CI [0.13-0.85]; p = 0.008, I2 = 0%). We did not find any association with mortality for early wave of transmitral flow/late (atrial) wave of trans-mitral flow ratio (six studies, n = 273; standardized mean difference 0.28, 95% CI [-0.42 to 0.99]; p = 0.43, I2 = 81%) and peak velocity of systolic mitral annular motion determined by tissue Doppler imaging wave measured at the tricuspid annulus (three studies, n = 148; standardized mean difference -0.18, 95% CI [-0.53 to 0.17]; p = 0.32, I2 = 0%). Only a few studies were conducted with strain echocardiography. CONCLUSIONS: This meta-analysis of echocardiography parameters in pediatric sepsis failed to find any association between the measures of left ventricular systolic or right ventricular function and mortality. However, mortality was associated with higher early wave of transmitral flow/peak velocity of early diastolic mitral annular motion determined by tissue Doppler imaging or lower peak velocity of early diastolic mitral annular motion determined by tissue Doppler imaging, indicating possible importance of left ventricular diastolic dysfunction. These are preliminary findings because of high clinical heterogeneity in the studies to date.

Cerebral Palsy and Epilepsy in Children: Clinical Perspectives on a Common Comorbidity.

Cerebral palsy (CP) is a frequent cause of childhood disability often associated with a complex group of disorders, including epilepsy, which is reported to impact approximately 40% of affected individuals. This retrospective study involved a group of children affected by CP, some of whom also had comorbid epilepsy. The aim of this study was to report our experience of analyzing, in particular, (a) some of the clinical aspects of the different type of CP, and (b) the relationship between the clinical data of children affected by CP plus epilepsy and each type of CP. METHODS: This retrospective single-center study was performed with 93 children admitted to the Pediatric Department of the University of Catania, Italy, affected by CP and distinguished according to the type of motor clinical presentation, with 46 showing epileptic seizures, compared to a control group of 136 children affected by epilepsy without other neurologic disorders. RESULTS: Among the 93 CP children, 25 (27%) had spastic quadriplegia (plus one patient with dystonic quadriplegia), 39 (42%) had spastic hemiplegia, 11 (12%) had spastic diplegia (plus two with ataxia and one with dyskinetic CP), and 14 (15%) did not have a well-defined type of CP. The frequency of epilepsy was higher in affected CP children who showed major motor dysfunction (GMFCS IV-V types). As regards the 46 children with CP plus epilepsy, compared to the group of the control, the age of epilepsy onset was found to be statistically significant: 21 ± 35.1 months vs. 67 ± 39.7. CONCLUSIONS: Epilepsy represents one of the most frequent comorbidities of cerebral palsy. In children with CP, particular attention should be paid to the early identification and treatment of comorbid epilepsy.

Efficacy of Three Different Prophylactic Treatments for Postoperative Nausea and Vomiting after Vitrectomy: A Randomized Clinical Trial.

Postoperative nausea and vomiting (PONV) after vitreoretinal surgery may potentially be associated with severe complications, such as suprachoroidal hemorrhage. The purpose of the present multicenter clinical trial (NCT02386059) was to assess the efficacy of three different prophylactic treatments for PONV after vitrectomy under local anesthesia. Patients undergoing primary vitrectomy were randomized to the control arm or to one of the treatment arms (4 mg ondansetron, 4 mg dexamethasone, combination of the two drugs). The primary outcome measure was the proportion of complete response (no nausea, no vomiting, no retching, and no use of antiemetic rescue medication) during 24 h after vitrectomy. Secondary outcomes included the severity standardized score of PONV, postoperative pain standardized score, and rate of ocular and non-ocular adverse events. Baseline demographics of the 1287 patients were comparable between the four arms. The combined therapy group showed a statistically significant lower incidence of PONV compared to the placebo and monotherapy (p < 0.001). PONV severity was also reduced in the combination group compared to the others (p < 0.001). Postoperative pain scores and adverse events were comparable among the four groups. Combined therapy with dexamethasone and ondansetron was the most effective treatment for reducing the incidence and severity of PONV in patients undergoing vitrectomy under local anesthesia.

Epilepsy in Children: From Diagnosis to Treatment with Focus on Emergency.

Seizures are defined as a transient occurrence of signs and symptoms due to the abnormal, excessive, or synchronous neuronal activity in the brain characterized by abrupt and involuntary skeletal muscle activity. An early diagnosis, treatment, and specific medical support must be performed to prevent Status Epilepticus (SE). Seizure onset, especially in the child population, is related to specific risk factors like positive family history, fever, infections, neurological comorbidity, premature birth, mother's alcohol abuse, and smoking in pregnancy. Early death risk in children without neurological comorbidity is similar to the general population. Diagnosis is generally based on the identification of continuous or recurrent seizures but Electroencephalogram (EEG) evaluation could be useful if SE condition is suspected. The main goal of therapy is to counteract the pathological mechanism which occurs in SE before neural cells are irreversibly damaged. According to the latest International Guidelines and Recommendations of seizure related diseases, a schematic and multi-stage pharmacological and diagnostic approach is proposed especially in the management of SE and its related causes in children. First measures should focus on early and appropriate drugs administration at adequate dosage, airway management, monitoring vital signs, Pediatric Intensive Care Unit (PICU) admission, and management of parent anxiety.

Remifentanil and worse patient-reported outcomes regarding postoperative pain management after thyroidectomy.

BACKGROUND: Intraoperative remifentanil has been associated with postoperative hyperalgesia, higher visual analogic pain scores, and increased postoperative morphine consumption. However, this has not been investigated from patient's perspective by using a patient-reported outcomes (PROs) approach with a validated questionnaire. METHODS: We joined the largest prospective observational study on postoperative pain, PAIN OUT Project (NCT02083835), and collected data for 2 years. We studied the effects of remifentanil (R+) vs nonremifentanil (R-) anesthesia on PROs regarding their pain management after elective thyroidectomy. We selected 5 primary PROs (worst pain experienced, time spent in severe pain, relief received by treatment, satisfaction about pain management, wish for more pain treatment) and five secondary PROs (drowsiness, itching, nausea, dizziness, waking up due to pain) from the validated International Pain Outcomes questionnaire. RESULTS: The analysis included 317 patients, 208 in the R+ group (65.6%) and 109 in the R- group (34.4%), the latter receiving fentanyl as intraoperative opioid. Although the R+ group received more frequently intraoperative nonopioids (202/208, 97.1% vs 86/109, 78.9%; P < .0001) and opioids (184/208, 88.5% vs 38/109, 34.9%; P < .001), it reported higher worst pain (5.1±2.1 vs 4.3±2.1, P < .005), lower satisfaction (7.4±2.0 vs 8.1±2.1, P < .001), and worse results in 4 secondary PROs. A sensitivity analysis performed matching 67 couples of patients yielded similar results in primary PROs. CONCLUSIONS: Our study suggests that remifentanil-based anesthesia is associated with worse pain-related PROs in patients undergoing thyroidectomy despite more frequent intraoperative analgesic administration. This study adds further evidence to the growing literature about opioid- and remifentanil-induced hyperalgesia.

Emergence delirium in children: a comparison of sevoflurane and desflurane anesthesia using the Paediatric Anesthesia Emergence Delirium scale.

OBJECTIVES/AIM: This randomized control trial was designed to evaluate the incidence of emergence delirium (ED) in preschool children receiving sevoflurane or desflurane anesthesia combined with an effective caudal block. BACKGROUND: While ED has been described in children receiving sevoflurane or desflurane anesthesia, a direct comparison between the two agents using a validated ED assessment tool has not been reported previously. METHODS/MATERIALS: Two hundred and sixty preschool children scheduled for elective sub-umbilical surgery were randomized to receive sevoflurane or desflurane anesthesia combined with a caudal block. ED was defined as a Paediatric Anesthesia Emergence Delirium scale (PAED) ≥ 10 points. A delirium-specific score (ED I) was calculated from the first three items of the PAED score (eye contact, purposeful actions, awareness of the surroundings) and a nonspecific score (ED II) from the last two items on the PAED score (restlessness and inconsolability) to test the hypothesis that some items of the PAED scale may better reflect clinical ED than others. RESULTS: Thirty-one (25%) children in each group demonstrated ED after awakening with ED being of shorter duration in the desflurane group than the sevoflurane group. An ED I score of nine points had a sensitivity of 0.93 and a specificity of 0.94 for ED. An ED II score of five points had a sensitivity of 0.34 and specificity of 0.95 for ED. CONCLUSION: Sevoflurane and desflurane anesthesia were associated with similar incidences of ED in children undergoing sub-umbilical surgery and receiving effective regional anesthesia. High scores on the first three items of the PAED scale were highly correlated with ED. The items restlessness and inconsolability had lower sensitivity for the diagnosis of ED.

Sedation and analgesia in pediatric intensive care.

Almost all children in the pediatric intensive care (PICU) need analgesia and/or sedation. Analgesics drugs are used to control pain from surgical incisions, drainages, vascular access or endotracheal suctioning. Sedatives are used to facilitate the delivery of nursing care, to facilitate mechanical ventilation, prevent self-extubation and to minimize patient discomfort. A therapeutic plan for analgesia and sedation should be established for each patient and regularly reviewed. The most often used sedation agents in PICU patients are Morphine or Fentanyl alone or in combination with Midazolam. Several other drugs should be helpful to manage PICU patients therefore techniques like regional anesthesia and patient controlled analgesia to decrease the use of intravenous analgesia and sedation and to reduce the incidence of withdrawal syndrome. The therapeutic plan for analgesia and sedation should be established for each patient and regularly reviewed. Doses of sedative agents should be titrated to produce the desired level of sedation. The level of sedation should be regularly assessed and documented using few validated sedation assessment tool. However, behavioral evaluation tools based on patient responsiveness, cannot be used during the administration of neuromuscular blocking agents. Under this conditions it could be difficult to interpret the degree of sedation. EEG derived Monitoring devices may represents an useful tools of assessing the level of sedation, but there is insufficient evidence to support the routine use of the BIS monitor in PICU.

A randomized controlled trial demonstrates that a novel closed-loop propofol system performs better hypnosis control than manual administration.

PURPOSE: The purpose of this randomized control trial was to determine the performance of a novel rule-based adaptive closed-loop system for propofol administration using the bispectral index (BIS(R)) and to compare the system's performance with manual administration. The effectiveness of the closed-loop system to maintain BIS close to a target of 45 was determined and compared with manual administration. METHODS: After Institutional Review Board approval and written consent, 40 patients undergoing major surgery in a tertiary university hospital were allocated to two groups using computer-generated block randomization. In the Closed-loop group (n = 20), closed-loop control was used to maintain anesthesia at a target BIS of 45, and in the Control group (n = 20), propofol was administered manually to maintain the same BIS target. To evaluate each technique's performance in maintaining a steady level of hypnosis, the BIS values obtained during the surgical procedure were stratified into four clinical performance categories relative to the target BIS: < or = 10%, 11-20%, 21-30%, or > 30% defined as excellent, good, poor, or inadequate control of hypnosis, respectively. The controller performance was compared using Varvel's controller performance indices. Data were compared using Fisher's exact test and the Mann-Whitney U test, P < 0.05 showing statistical significance. RESULTS: In the Closed-loop group, four females and 16 males (aged 54 +/- 20 yr; weight 79 +/- 7 kg) underwent anesthesia lasting 143 +/- 57 min. During 55%, 29%, 9%, and 7% of the total anesthesia time, the system showed excellent, good, poor, and inadequate control, respectively. In the Control group, five females and 15 males (aged 59 +/- 16 yr; weight 75 +/- 13 kg) underwent anesthesia lasting 157 +/- 81 min. Excellent, good, poor, and inadequate control were noted during 33%, 33%, 15%, and 19% of the total anesthesia time, respectively. In the Closed-loop group, excellent control of anesthesia occurred significantly more often (P < 0.0001), and poor and inadequate control occurred less often than in the Control group (P < 0.01). The median performance error and the median absolute performance error were significantly lower in the Closed-loop group compared with the Control group (-1.1 +/- 5.3% vs -10.7 +/- 13.1%; P = 0.004 and 9.1 +/- 1.9% vs 15.7 +/- 7.4%; P < 0.0001, respectively). CONCLUSION: The closed-loop system for propofol administration showed better clinical and control system performance than manual administration of propofol. (Clinical Trials gov. NCT 01019746).

Sevoflurane causes less arrhythmias than desflurane after off-pump coronary artery bypass grafting: a pilot study.

BACKGROUND: Volatile anesthetics provide myocardial protection during cardiac surgery. Sevoflurane and desflurane are both efficient agents that allow immediate extubation after off-pump coronary artery bypass grafting (OPCABG). This study compared the incidence of arrhythmias after OPCABG with the two agents. MATERIALS AND METHODS: Forty patients undergoing OPCABG with immediate extubation and perioperative high thoracic analgesia were included in this controlled, double-blind study; anesthesia was either provided using 1 MAC of sevoflurane (SEVO-group) or desflurane (DES-group). Monitoring of perioperative arrhythmias was provided by continuous monitoring of the EKG up to 72 hours after surgery, and routine EKG monitoring once every day, until time of discharge. Patient data, perioperative arrhythmias, and myocardial protection (troponin I, CK, CK-MB-ratio, and transesophageal echocardiography examinations) were compared using t-test, Fisher's exact test or two-way analysis of variance for repeated measurements; P < 0.05. RESULTS: Patient data and surgery-related data were similar between the two groups; all the patients were successfully extubated immediately after surgery, with similar emergence times. Supraventricular tachycardia occurred only in the DES-group (5 of 20 patients), atrial fibrillation was significantly more frequent in the DES group versus SEVO-group, at five out of 20 versus one out of 20 patients, respectively. Myocardial protection was equally achieved in both groups. DISCUSSION: Ultra-fast track anesthesia using sevoflurane seems more advantageous than desflurane for anesthesia, for OPCABG, as it is associated with significantly less atrial fibrillation or supraventricular arrhythmias after surgery.

Does the Italian pediatric anesthesia training program adequately prepare residents for future clinical practice? What should be done?

BACKGROUND: Pediatric anesthesia should be considered a subspecialty addressing the complete pediatric population (from preterm to teenager) and requiring particular anatomical, pathophysiological, pharmacological and anesthesiological knowledge. A survey was conducted to evaluate the training in pediatric anesthesia performed by Medical Schools of Anesthesia in Italy and to assess if the European Federation of Associations of Pediatric Anesthesia (FEAPA) guidelines for training in pediatric anesthesia had been adopted. METHODS: The survey was addressed to the Directors of the Departments of Anesthesia and Intensive Care of the Medical Schools throughout Italy using a questionnaire. RESULTS: We contacted all 37 Schools of Anesthesia, but only 26 of these (70 %) answered all the questions. A specific training program exists in 24 (92%). The duration of the training is variable: in 40% of the schools it lasts 2 months, in 27% 3 months and in 33% more than 3 months (3-6 months). Only 29% of the Schools required a minimum number of procedures to be performed during the training period. A final test is performed in 46% of the Schools. A dedicated staff for pediatric anesthesia exists in 70% of the Italian Schools. CONCLUSIONS: In Italy, the FEAPA guidelines have not yet been completely adopted. The experience of a dedicated unit for pediatric anesthesia will be invaluable to define operative guidelines, courses and to establish the minimum equipment necessary for pediatric management in nonspecialist hospitals.
