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
BACKGROUND: During inhalational induction of anaesthesia for children, severe respiratory events can occur but can be rapidly treated once intravenous access is in place. Reducing the time to successful cannulation during inhalational induction for children with poor vein visibility would improve safety. OBJECTIVE: To study the effectiveness of a near-infrared (NIR) vascular imaging device (Veinviewer) to facilitate intravenous cannulation. DESIGN: A prospective, multicentre, randomised, open clinical trial. SETTING: The operating rooms of three paediatric hospitals in Paris, France, from 1 October 2012 to 31 March 2016. PATIENTS: Children up to the age of 7âyears, with poor vein visibility requiring general anaesthesia. INTERVENTION: Inhalational anaesthesia was initiated and intravenous cannulation was performed with the standard approach or with the Veinviewer Vision. MAIN OUTCOME MEASURES: The primary outcome was the time to successful intravenous cannulation. A secondary outcome was the proportion of successful first attempts. RESULTS: The mean time to successful intravenous cannulation was 200 (95% CI, 143 to 295) seconds in the Veinviewer and 252 (95% CI, 194 to 328) seconds for the control group: hazard ratio 1.28 (1.02 to 1.60) (Pâ=â0.03). The adjusted hazard ratio for known predictive factors was 1.25 (0.99 to 1.56) (Pâ=â0.06). Success at the first attempt was 64.6% (102/158) in the 'Veinviewer' group vs. 55.6% (85/153) in the 'control' group (Pâ=â0.10). CONCLUSION: The Veinviewer has limited value in reducing the time to successful intravenous cannulation during inhalational anaesthesia for young children with poor vein visibility. However, there is a strong trend to reducing the delay in some cases and, given its absence of side effects, it could be part of a rescue option for a difficult venous-access strategy.

OBJECTIVE: To review the results of an anesthesiologist led pediatric percutaneous central venous access service. METHODS: Prospective data on percutaneous pediatric central venous catheter (CVC) insertions were collected over 22 years. Data included age, gender, weight, previous central CVCs, venous thromboses, investigations for great vein patency, type of CVC, external diameter, previous CVC insertions, intended use, operator identity, and the vein into which the CVC was inserted. The default technique was internal jugular vein cannulation using landmark technique (LT). Complication was defined as the following: failure to cannulate any vein, hemothorax, pneumothorax, right atrial perforation, extravenous wire positioning or CVC position and whether the patient was taken back to theater for CVC repositioning. RESULTS: Five thousand four hundred and thirty-four percutaneous CVC insertion procedures were performed on 3954 patients. One-third involved children <1 year of age (n = 1823: 34%). Five thousand one hundred and twenty-five CVCs (95.3%) were inserted into internal jugular veins. The majority were tunneled CVCs (n = 5190: 96.2%). The perioperative complication rate was 1.3%. Successful cannulation occurred in 99.5% of patients. Failure was more likely in children <3 kg, during large bore hemodialysis CVC insertions and during the first 4 years of the service - the latter suggesting a learning curve. Ninety-nine percent of CVCs were inserted using LTs. CONCLUSION: This study demonstrates a high success rate and low complication rate during pediatric percutaneous internal jugular vein CVC insertions by trained anesthesiologists using LTs. Smaller children, hemodialysis CVCs, and the team's learning curve were identified as risk factors for insertion failure.

Background: Robot-assisted pyeloplasty is the most frequently performed robotic procedure in children. A retroperitoneal approach limits surgical trauma and avoids peritoneal irritation. This led to the establishment of the criteria for day surgery (DS) and a related clinical care pathway. Objective: To assess the feasibility and safety of DS in children undergoing retroperitoneal robot-assisted laparoscopic pyeloplasty (R-RALP). Design setting and participants: We performed a bicentric prospective study (NCT03274050) over 2 yr involving the two major paediatric urology teaching hospitals in Paris. A clinical pathway and a prospective research protocol were specifically established. Intervention: DS in selected children undergoing R-RALP. Outcome measurements and statistical analysis: The primary outcomes were DS failure, 30-d complications, and readmission rates. The secondary outcomes included preoperative characteristics, perioperative parameters, and surgical outcomes. Quantitative variables were expressed as medians with interquartile ranges. Results and limitations: Thirty-two children fulfilled specific inclusion criteria and were consecutively selected for DS following R-RALP. The median patient age was 7.6 yr (4.1-11.8) and weight 25 kg (14-45). The median console time was 137 min (108-167). There were no intraoperative complications or conversions. Six children were kept under observation overnight and discharged the following day due to persistent pain (n = 3), parental anxiety (n = 2), or a prolonged procedure (n = 1). The median duration of hospital stay of the 26 children in the DS setting was 12.7 h (12.2-13.2). During the 30-d period, there were four emergency room visits (15%) resulting in two patients requiring readmission (8%): one for febrile urinary tract infection (Clavien-Dindo II) and one child with no JJ stent for urinoma (Clavien-Dindo IIIb). Radiological studies confirmed improvement in dilatation for all cases with no recurrence (median follow-up: 15 mo). Conclusions: This prospective case series is the first to demonstrate the feasibility and safety of DS in children undergoing R-RALP, obviating the need for routine inpatient care. Excellent results can be achieved by careful patient selection, a clear clinical pathway, and a dedicated team. Further evaluation is warranted to assess the cost effectiveness. Patient summary: This study shows that day surgery after robotic pyeloplasty is both safe and effective in selected children.
RESUMEN
OBJECTIVES: The main objective of this meta-analysis was to assess the accuracy of the Sleep-Related Breathing Disorder (SRBD) Scale in the diagnosis of obstructive sleep apnea syndrome (OSAS) in children. PATIENTS/METHODS: A literature search of studies comparing SRBD to polysomnography for the diagnosis of OSAS in children was performed. Risks of biases were quantified using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS) tool. Analyses determined the summary receiver operator characteristic area under the curve (SROC), the pooled sensitivity (Se), the specificity (Sp), and the positive and negative likelihood ratios (LR+ and LR-). Results were graded and are expressed as means [95% confidence interval]. Post-test probabilities were computed for various populations. RESULTS: Eleven studies were included; and two were considered to have high risk of bias. The SROC was 0.73 [CI: 0.63; 0.82]. The combined Se, Sp, LR+ and LR- were: 0.72 [CI: 0.68; 0.77], 0.59 [CI: 0.56; 0.63], 1.74 [CI: 1.32; 2.30], 0.53 [CI: 0.39; 0.71], respectively. Sub-group analyses displayed similar results in comparison to overall results. GRADE evidence for the overall analysis was low to moderate. Finally, pre-test to post-test probabilities were estimated to be: 3.5%-1%, 50%-30% and 75%-30%, for the general population, the obese patients and the patients assigned for surgical treatment of OSAS, respectively. CONCLUSIONS: The current meta-analysis indicates that the SRBD scale has acceptable accuracy in detecting patients with OSAS. It may be useful when evaluating patients with suspected OSAS before surgery. STUDY REGISTRATION: PROSPERO database (CRD42018088216).

OBJECTIVE: Thiopurine drugs are commonly used in pediatric patients for the treatment of acute leukemia, organ transplantation and inflammatory diseases. They are catabolized by the cytosolic thiopurine methyltransferase (TPMT), which is subject to a genetic polymorphism. In children, enzyme activities are immature at birth and developmental patterns vary widely from one enzyme to another. The present study was undertaken to evaluate erythrocyte TPMT activity and the correlation between genotype and phenotype in different age groups from birth to adolescence and adulthood. METHODS: The study included 304 healthy adult blood donors, 147 children and 18 neonates (cord bloods). TPMT activity was measured by liquid chromatography, and genotype was determined using a polymerase chain reaction reverse dot-blot analysis identifying the predominant TPMT mutant alleles (TPMT*3A, TPMT*3B, TPMT*3C, TPMT*2). RESULTS: There was no significant difference in TPMT activity between cord bloods ( n=18) and children ( n=147) (17.48+/-4.04 versus 18.62+/-4.14 respectively, P=0.424). However, TPMT was significantly lower in children than in adults (19.34+/-4.09) ( P=0.033). In the whole population, there were 91.9% homozygous wild type, 7.9% heterozygous mutants and 0.2% homozygous mutants. The frequency of mutant alleles was 3.0% for TPMT*3A, 0.7% for TPMT*2 and 0.4% for TPMT*3C. CONCLUSION: No impact of child development on TPMT activity could be evidenced, suggesting that TPMT activity is already mature at birth. The difference between children and adults was low with reduced clinical impact expected. When individual TPMT activity was compared with genotype, there was an overlapping region where subjects (4.5%, 12 adults, 9 children) were either homozygous wild type or heterozygous, with a TPMT activity below the antimode value. This result highlighted the importance of measuring TPMT activity to detect all patients at risk of thiopurine toxicity.
