RESUMO
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.
RESUMO
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.

PURPOSE: The aim of this work is to study a cohort of patients of ISS < 15 admitted to a TC, and to determine the number of patients that ultimately benefited from the skills and resources specific of a level 1 trauma center. METHODS: Retrospective study from a prospective cohort of patients admitted to TC (Beaujon Hospital, APHP) for suspected severe trauma from January 2011 to December 2017. The main outcome criterion was the use of surgery or interventional radiology within the first 24 h after admission of patients with ISS < 15. The secondary outcomes were stratified into severe (mortality, resuscitation care, length of stay in intensive care units) and non-severe criteria (mild head injury, hospital discharge or transfer within 24 h). RESULTS: Of 3035 patients admitted during the study period, 1409 with an ISS < 15 were included, corresponding to a theoretical overtriage rate of 46.4%. Among these, 611 patients (43.4%) underwent emergency intervention within the first 24 h (586 surgical interventions, 19 direct transfers to the operating theater and 6 acts of interventional radiology), 238 (16.9%) of patients presented with severe and 531 (38%) with non-severe outcome criteria. CONCLUSION: This work demonstrates that in a cohort of patients classified as ISS < 15 admitted to a TC, a considerable amount of TC-specific resources are required, and patients present with severe outcome criteria despite being classified as overtriaged. These results suggest that triage of trauma patients should be based on resource use and clinical outcome rather than anatomic criteria.
