RESUMEN
BACKGROUND: The administration of intravenous lidocaine during the peri-operative period may improve pain management after paediatric surgery. OBJECTIVE: To explore the decrease in postoperative pain intensity and opioid consumption associated with peri-operative lidocaine administration in the paediatric population. DESIGN: A systematic review with meta-analysis of randomised controlled trials and a Grading of Recommendations Assessment, Development and Evaluation (GRADE) analysis. DATA SOURCES: Extensive literature review. ELIGIBILITY CRITERIA: This study includes clinical trials conducted during surgery that examined the effect of intravenous lidocaine compared with placebo on postoperative pain management. RESULTS: Lidocaine administration decreased pain intensity in PACU (standardised mean difference (SMD)â=â-1.89 [-3.75, -0.03], I2â=â97%, P of I2â<â0.001) and on postoperative day 1 (SMDâ=â-2.02 [-3.37, -0.66], I2â=â96%, P of I2â<â0.001, number of studiesâ=â5). Lidocaine was associated with a decrease in opioid consumption on postoperative day 1 (SMDâ=â-1.2 [-2.19, -0.2], I2â=â93%, P of I2â<â0.001) but not on postoperative day 2 (SMDâ=â-1.73 [-3.9, 0.44], I2â=â96%, P of I2â<â0.001). GRADE analyses resulted in low-quality results. Subgroup analyses revealed that pain intensity in PACU and opioid consumption on postoperative day 1 decreased when lidocaine was administered during both the intra-operative and postoperative periods. CONCLUSIONS: The use of lidocaine is associated with improved pain management. However, further studies are needed to increase the level of evidence and determine the optimal administration regimen for pain management.
RESUMEN
PURPOSE: Patient blood management has been recently emphasized to avoid perioperative blood transfusion in AIS surgery. Hydroxyapatite charged collagen sponge (HCS) is a bone substitute material made of collagen and ceramized hydroxyapatite, with associated haemostatic properties. The goal of this study was to assess the impact of HCS in the perioperative blood loss in AIS surgery. METHODS: After IRB approval, all AIS patients undergoing primary correction were prospectively included over a 15-month period. Patients receiving HCS at the end of the procedure were compared to a control group (matched for age, gender, and fusion levels) without any haemostatic agent or bone substitute. The same perioperative blood saving strategies were used in both groups. Two subfascial drains were used for 48 h in all patients. Perioperative blood loss and transfusion rates were analysed. RESULTS: A total of 34 patients were included in each group. No difference in drainage volume was observed at day 1, but the reduction was statistically different at day 3 (1135 mL [800-1640] versus 930 [480-1510], p = 0.028, 0.63 ml/Kg/h [0.4-0.92] versus 0.46 [0.29-0.7], p = 0.042). Multivariate analysis found that the use of HCS was associated with a decrease in the postoperative blood loss (OR = 1.17 [1.10-1.25]). The transfusion rate was lower in the HCS group [0 (0% vs. 3(8.8%), p = 0.076)]. No infection occurred, and no complication was reported. CONCLUSION: With 27% reduction in drain volume, hydroxyapatite charged collagen sponge can be considered as a blood salving strategy in AIS surgery. The role of the biomaterial in fusion rate still needs to be further assessed.

INTRODUCTION: Bleeding and transfusion remain important concerns during surgical correction of scoliosis even when multiple conservative strategies, such as preoperative recombinant erythropoietin and/or antifibrinolytic agents, are used. The current work aimed to determine the impact of other potential risk factors, especially the volume of intraoperative fluid intake, on the perioperative risk of allogenic transfusion during surgical correction of adolescent idiopathic scoliosis. METHODS: This prospective study included all cases of adolescent idiopathic scoliosis operated in a single center during 2 years (2018-2020). Predictors analyzed were as follows: body mass index, preoperative hemoglobin concentration, thoracoplasty, preoperative halo-gravity, volume of intraoperative crystalloid administration, use of esophageal Doppler (for goal-directed fluid therapy), and duration of surgery. Statistical analyses were performed using a multivariable logistic regression model. RESULTS: Two hundred patients were included in the analysis. Multivariable analysis found: an increased volume of intraoperative crystalloid administration as a significant predictor of allogenic blood transfusion. Receiving operator characteristics analysis found the model exhibiting an area under the curve of 0.85 (95% confidence interval: 0.75-0.95). Optimizing stroke volume using esophageal Doppler was associated with a decrease in intraoperative crystalloid intake. CONCLUSION: These results indicate a statistical association between the increase in crystalloid intake and the risk of allogenic blood transfusion during surgical correction of adolescent idiopathic scoliosis. Controlled studies are needed to address the causative relation between intraoperative fluid intake and the risk of allogenic transfusion.

BACKGROUND: The goal of the present study was to investigate intraoperative factors associated with major neurological complications at 1 year following surgery for necrotizing enterocolitis. MATERIAL AND METHODS: The study consisted of a retrospective review of medical charts of patients operated for over one calendar year in one institution. Data collected included demographic data, cardiac resuscitation at birth, Bell classification, antibiotics usage, time of day of surgery, surgical technique, surgical duration, type of ventilation, intraoperative vasoactive agents, and albumin use, nadir cerebral saturation, the decrease in cerebral saturation from baseline, the time period when cerebral saturation was at least 20% below baseline, and the mean arterial pressure at nadir cerebral saturation. Reported follow-up complications were assessed during formal neonatologist consultation and additional imaging exploration as needed. Analyses included descriptive statistics, and univariable and multivariable statistics. RESULTS: The study included 32 patients with no prior clinical neurological complications, of which 25 had normal cerebral imaging. Severe neurological complications occurred in nine patients at 1 year: Intraventricular hemorrhage (N = 2) and Periventricular leukomalacia (N = 7). However, preoperative cerebral imaging was lacking in seven patients. Consequently, the observed neurological complications at 1 year might be present before the surgery. Multivariable analysis found the decrease in cerebral saturation ≥36% from baseline as the only factor associated with the occurrence of those complications. CONCLUSION: Intraoperative decrease of cerebral oxygen saturation below ≥36% from baseline is associated with severe neurological complications in neonates undergoing surgery for necrotizing enterocolitis.

BACKGROUND: Little evidence is available regarding work-related quality of life (WRQoL) for anesthesiologists. We aimed to explore factors associated with WRQoL among French anesthesiologists. METHODS: The study surveyed French anesthesiologists qualified for more than 2 years. The primary objective was the determination of factors associated with WRQoL. Factors analyzed included demographic characteristics, lifestyle, financial status, personality traits, professional relations, management and organization, and occupational tasks when at work. Statistical analyses were performed using a multivariable quantile regression model. RESULTS: Overall, 2040 anesthesiologists responded to the survey and 1922 responses were analyzed. The latter represents 19% of practicing French anesthesiologists. The following factors were independently associated with increased WRQoL: family income, long-term employment, organizational and managerial factors (lesser weekly workload, the belief of providing high quality, safe health care services, team management, and operating theatre organization), human relations (satisfaction with workplace ambiance and relations with hospital management and colleagues), and occupational tasks (participation in team activities). Three personality traits were found to be significantly associated with increased WRQoL: extraversion, conscientiousness, and openness. Neuroticism was associated with reduced WRQoL. CONCLUSIONS: The current study demonstrates exogenous and endogenous factors associated with increased WRQoL in anesthesiologists. Results should be considered as explorative and provide hypotheses for further research in this domain.

PURPOSE: Definitive fusion can be considered in early onset scoliosis (EOS) around triradiate cartilage closure. Halo-gravity traction (HGT) is an old strategy that can help lengthen and balance the spine before fusion. The postoperative changes of the trunk have never been investigated to date with modern imaging. The goal of this study was to analyze the 3D radiological outcomes, and the associated pulmonary function, of a cohort of severe EOS patients treated by definitive posterior fusion prepared by HGT. METHODS: All consecutive EOS patients with severe (> 85°) and stiff (flexibility < 25%) curves, treated by HGT followed by posterior fusion, were followed. 3D radiological measurements and pulmonary function were assessed. RESULTS: Forty-nine EOS patients underwent fusion, with a mean follow-up of 4 years (± 1). Age at surgery averaged 13.5 years old. HGT protocol reached on average 41% of body weight. Mean preoperative 3D Cobb angle was 95° (± 10) and final correction averaged 68.4% after surgery. 3D T4T12 kyphosis was reduced after surgery (11°, p < 0.01), while the apical vertebral rotation was improved by 27.8% (p = 0.06). 3D thoracic volume increased after surgery (p = 0.02), with a 3D T1T12 height gain averaging 3.7 cm (± 2). Both parameters were significantly correlated with total lung capacity improvement. Seven complications (14.2%) were reported, and 5 patients (10.6%) underwent unplanned revision. CONCLUSION: HGT is a safe and efficient strategy to prepare posterior fusion in severe EOS patients. The 3D trunk analysis demonstrated significant postoperative gains in thoracic and spinal lengths, as well as in thoracic volume. LEVEL OF EVIDENCE: IV.

BACKGROUND: Few publications in the literature examine enhanced recovery after scoliosis surgery (ERAS) in children, despite significant scientific interest in adults. The objective of the current study was to describe an ERAS protocol for surgical correction of adolescent idiopathic scoliosis (AIS) and its results. METHODS: ERAS outcomes were measured in two patient cohorts. Historical controls and ERAS groups were selected from patients managed for scoliosis surgery in 2015 and 2018, respectively. The ERAS protocol included fasting minimization, carbohydrate loading, the avoidance of background morphine infusions, perioperative opioid-sparing protocols, the use of a cooling brace, early physiotherapy, feeding and oral medications, and the early removal of urinary catheters and surgical drains. The main outcome of the study was hospital length of stay. RESULTS: Overall, 82 controls and 81 ERAS patients were recruited. ERAS protocols were observed in over 80% of patients for almost items. Median length of hospital stay was significantly lower in the ERAS group (- 3 [95% confidence interval: -2; -4] days). Median morphine consumption was reduced by 25% and 35% on days 2 and 3, respectively. The incidence of PONV did not differ between the two groups, and the incidence of constipation decreased slightly but significantly in the ERAS group on day 2. Pain intensity at rest and movement were lower in the ERAS group at day 2 and 3. CONCLUSIONS: The current study suggests an ERAS protocol after adolescent idiopathic scoliosis surgery is associated with reduced hospital length of stay and improved postoperative care.

PURPOSE: To evaluate the impact of the COVID-19 pandemic-related lockdown on management and outcomes of children with acute appendicitis. METHODS: A retrospective cohort study was conducted, including children treated for acute appendicitis (January 20th-May 11th, 2020). The data regarding the severity of appendicitis and outcome were collected and compared for two time periods, before and after the nationwide lockdown (March 17th, 2020). RESULTS: The number of cases of acute appendicitis increased by 77% during the lockdown (n = 39 vs. n = 69, p = 0.03). During the lockdown, children treated for appendicitis were older (11.1 vs. 8.9 years, p = 0.003), and were more likely to live more than 5 km away from our institution (77% vs. 52%, p = 0.017). Less children had previously consulted a general practitioner (15% vs. 33%, p = 0.028), whereas more children were transferred from other hospitals (52% vs. 31%, p = 0.043). There was no difference in terms of length of hospital stay, rate of postoperative intra-abdominal abscess, ER visits, and readmissions between both periods. Three children (4%) were diagnosed with COVID-19 and appendicitis. CONCLUSIONS: Despite an increase in the number of children with appendicitis managed at our hospital during the COVID-19-related lockdown, management, and outcome remained similar. Although our pediatric center was strongly affected by this pandemic, maintaining our prior practice strategies for acute appendicitis avoided the occurrence of collateral damage for those children.

AIM OF THE STUDY: Mowat Wilson syndrome (MWS) is a complex genetic disorder due to mutation or deletion of the ZEB2 gene (ZFHX1B), including multiple clinical features. Hirschsprung disease is associated with this syndrome with a prevalence between 43 and 57%. The aim of this study was to demonstrate the severe outcomes and the high complication rates in children with MWS, focusing on their complicated follow-up. METHODS: A retrospective comparative study was conducted on patients referred to Robert-Debré Children's Hospital for MWS from 2003 to 2018. Multidisciplinary follow-up was carried out by surgeons, geneticists, gastroenterologists, and neurologists. Data regarding patient characteristics, surgical management, postoperative complications, and functional outcomes were collected. RESULTS: Over this period of 15 years, 23 patients were diagnosed with MWS. Hirschsprung disease was associated with 10 of them (43%). Of these cases, two patients had recto-sigmoïd aganglionosis (20%), three had aganglionic segment extension to the left colic angle (30%), two to the right colic angle (20%), and three to the whole colon (30%). The median follow-up was 8.5 years (2 months-15 years). All patients had seizures and intellectual disability. Six children (60%) presented with cardiac defects. At the last follow-up, three patients still had a stoma diversion and 7 (70%) were fed orally. One patient died during the first months. Eight (80%) of these children required a second surgery due to complications. At the last follow-up, three patients reported episodes of abdominal bloating (42%), one recurrent treated constipation (14.3%), and one soiling (14.3%). Genetic analysis identified three patients with heterozygous deletions, three with codon mutations, and three with frameshift mutations. CONCLUSIONS: MWS associated with Hirschsprung disease has a high rate of immediate surgical complications but some patients may achieve bowel function comparable with non-syndromic HD patients. A multidisciplinary follow-up is required for these patients. LEVEL OF EVIDENCE: Retrospective observational single cohort study, Level 3.

BACKGROUND: Renal transplantation is the best available therapeutic option for end-stage renal failure in both children and adults. However, little is known about anesthetic practice during pediatric renal transplantation. MATERIAL AND METHODS: The study consisted of a national survey about anesthetic practice during pediatric renal transplantation in France. French tertiary pediatric centers performing renal transplants were targeted, and one physician from each team was asked to complete the survey. The survey included patient data, preoperative assessment and optimization data, and intraoperative anesthesia data (drugs, ventilation, and hemodynamic interventions). RESULTS: Twenty centers performing kidney transplantation were identified and contacted to complete the survey, and eight responded. Surveyed centers performed 96 of the 122 pediatric kidney transplantations performed in France in 2017 (79%). Centers consistently performed echocardiography and ultrasound examinations of the great veins preoperatively and consistently employed esophageal Doppler cardiac output estimation and vasopressors intraoperatively. All other practices were found to be heterogeneous. Central venous pressure was monitored in six centers, and dopamine was administered perioperatively in two centers. CONCLUSIONS: The current study provides a snapshot of the perioperative management of pediatric kidney transplantation in France. Results emphasize the need for both standardization of practice and awareness of recent evidence against the use of CVP monitoring and dopamine infusions.

RESUMEN
PURPOSE: The aim of this study was to investigate the opioid-sparing effect of a cooling brace after surgical correction of idiopathic surgery in children. METHODS: We compared two consecutive cohorts of patients before and after introducing this technique in our institution. Management of patients was standardized. The primary objective of the study was to investigate the morphine consumption during the first postoperative day. Secondary outcomes were opioid consumption at day 3, pain intensity (at days 1 and 3), the mobilization in the standing position and duration of hospitalization. RESULTS: This study included 23 and 22 patients in the control and the cooling cohorts. Cooling brace was associated with a significant decrease in morphine consumption at day 1 (1.7 [0.9, 3.3] versus 1.2 [0.5, 3.2] mg kg-1, P = 0.02) and day 3 (2.5 [0.5, 6.7] versus 1.2 [0.9, 2.5] mg kg-1, P = 0.003), and a reduction in duration of hospitalization (4 [3, 6] versus 3 [3, 4] days, P = 0.004). However, no difference was found on the pain intensity or the percentage of patient mobilized in the standing position. Number of level fused and intraoperative opioid consumption were also different between the two cohorts. However, multivariate analysis found only the use of the cooling brace as significantly associated with opioid consumption at day 1. CONCLUSION: The use of this cooling brace allows decreasing the opioid use after surgical correction of idiopathic surgery in children. The current results strongly suggest an interest of this technique in the postoperative management of patients. These slides can be retrieved under Electronic Supplementary Material.

BACKGROUND: Hydroxyethyl starch (HES) solutions have shown their efficiency for intravascular volume expansion. A safety recommendation limiting their use in adult patients has recently been made. OBJECTIVE: To assess the efficacy and adverse effects of HES when administered intra-operatively to paediatric patients. DESIGN: Systematic review with meta-analyses. Data were analysed using classical mean differences [and their 95% confidence intervals (CIs)] and trial sequential analysis. A Grading of Recommendations Assessment, Development and Evaluation (GRADE) classification was performed for all outcomes. Reviewers extracted valid data, including perioperative total fluid intakes, mortality, renal function, coagulation tests, blood loss and length of hospital and ICU stay. DATA SOURCES: Searches were performed in databases (Pubmed, Embase, Cochrane central register of controlled trials), clinical trials register, and open access journals not indexed in major databases. ELIGIBILITY CRITERIA: Randomised controlled trials (RCTs) published before December 2016 involving paediatric patients who received 6% low molecular weight HES. RESULTS: Nine RCTs involving 530 peri-operative paediatric patients were analysed. Compared with other fluids, HES did not significantly modify the amount of peri-operative fluid administered [mean difference 0.04; 95% CI (-1.76 to 1.84) ml kg], urine output [mean difference -33; 95% CI (-104 to 38) ml kg] or blood loss [mean difference -0.09; (-0.32 to 0.15) ml kg]. Trial sequential analysis determined that the outcomes for peri-operative fluid and urine output were underpowered. All results were graded as very low quality of evidence. CONCLUSION: Intravascular volume expansion with low molecular weight 6% HES did not appear to modify renal function, blood loss or transfusion when administered to children during the peri-operative period. However, given the lack of statistical power and the very low GRADE quality of evidence, more high-quality RCTs are needed to explore these outcomes.

BACKGROUND: Peri-operative respiratory adverse events (PRAEs) in paediatric patients with upper respiratory tract infections (URTIs) remain inadequately explored in patients allowed to proceed to anaesthesia and surgery. OBJECTIVE: To determine the incidence and risk factors of PRAE in children with URTI allowed to proceed to anaesthesia. DESIGN: Multicentre cohort study performed over 6 months in France. SETTING: Sixteen centres with dedicated paediatric anaesthetists. PATIENTS: Eligible patients were aged from 0 to 18 years with URTI symptoms on admission or a history of such over the preceding 4 weeks. MAIN OUTCOMES: The primary outcome of the study was to determine predictors of PRAE. Secondary outcomes were: predictors of peri-operative arterial desaturation and of the decision to proceed with anaesthesia and surgery in children with URTI. RESULTS: Overall, 621 children were included and 489 (78.7%) anaesthetised. Of those anaesthetised, 165 (33.5%) and 97 (19.8%) experienced PRAE and arterial desaturation, respectively. Factors predictive of PRAE included patient age, tracheal intubation and the absence of midazolam premedication. Factors predictive of peri-operative arterial desaturation included patient age, anaesthetist experience, endoscopic procedures and the presence of other PRAE. Factors predicting proceeding to anaesthesia in the context of URTI included anaesthetist experience, emergency procedures and the absence of severe URTI symptoms. CONCLUSION: The risk of PRAE in patients anaesthetised in the presence of URTI was similar to previous publications - close to 30%. In the light of our findings, first, current rescheduling indications should be questioned, and second, further medical and organisational strategies should be investigated to reduce PRAE in children with URTI. TRIAL REGISTRATION: The study was registered in the European Networks of Centers for Pharmacoepidemiology and Pharmacovigilance (EUPAS16436).

BACKGROUND: Muscle relaxation for tracheal intubation during paediatric anaesthesia remains a subject of debate. OBJECTIVE: The aim of the current meta-analysis was to investigate the effect of muscle relaxants (MR) compared with opioids on intubation conditions in children. DESIGN: Meta-analysis of randomised controlled studies. DATA SOURCES: Exhaustive literature analysis. ELIGIBILITY CRITERIA: Clinical trials, with no high-risk bias, that examined the effect of MR in comparison with opioids on intubation conditions (excellent: primary outcome, acceptable: secondary outcome) in children were included. RESULTS: Excellent intubation conditions were not significantly different in their occurrence between children receiving MR or opioids, risk ratio [95% Confidence Interval] â=â1.17 [0.96, 1.43], Iâ=â36%, number of studiesâ=â5, number of patientsâ=â226. However, trial sequential analysis indicated the lack of power of this result and the need for more trials to provide certainty for this outcome (81 patients needed in future trials). Acceptable intubation conditions were more frequent when administering MR, risk ratioâ=â1.25 [1.06, 1.47], Iâ=â70%, number of studiesâ=â6, number of patientsâ=â362. This effect was confirmed using the trial sequential analysis. Grading of Recommendations Assessment, Development and Evaluation analysis found a low and moderate quality of evidences for excellent and acceptable intubation conditions, respectively. CONCLUSION: The current meta-analysis shows that the use of MR during tracheal intubation might improve the quality of intubation conditions. Further studies, including at least 81 children, are required to confirm this and determine the impact of MR on complications related to intubation.
