Association between cuffed tracheal tube use and reduced ventilator-associated pneumonia and conditions after elective cardiac surgery in infants and young children.

BACKGROUND: Ventilator-associated pneumonia (VAP) is a serious complication in children after cardiac surgery that may result from micro-aspiration. However, the current recommendation to use cuffed tracheal tubes (TTs) versus uncuffed TTs in children is still uncertain. Our main aim was to evaluate the incidence of VAP, ventilator-associated tracheobronchitis (VAT) and ventilator-associated conditions (VAC) in children up to five years old who underwent elective cardiac surgery. METHODS: Single-center, prospective before-and-after study at a tertiary pediatric intensive care unit (PICU) in Italy. 242 patients (121 in each group) through the following periods: phase I (from Jan 2017 to 20th Feb 2018), during which children were intubated with uncuffed TTs; phase II (from 21th Feb 2018 to Feb 2019), during which children were intubated with cuffed TTs. RESULTS: Data were collected using an electronic dedicated database. Median age was five months. The use of cuffed tubes reduced the risk of VAC and VAP respectively 15.8 times (95% CI 3.4-73.1, P=0.0008) and 14.8 times (95% CI 3.1-71.5, P=0.002). No major related airway complications were observed in the cuffed TTs group. Average treatment effect, calculated after propensity score matching, confirmed the significant effect of cuffed TTs on VAC and VAP. CONCLUSIONS: Our study suggests a marked reduction of VAP and VAC associated with use of a cuffed versus uncuffed TT in infants and children ≤5 years of age after elective cardiac surgery. A randomized clinical trial is needed to confirm these results and define the impact of use of a cuffed versus uncuffed TT across other relevant ICU outcomes and non-cardiac PICU patients.

The impact of a standardized perioperative management on hospital mortality after the Norwood procedure in a low volume center: results and perspectives.

BACKGROUND: Mortality of newborns with Hypoplastic Left Heart Syndrome (HLHS) is mainly concentrated after Norwood procedure (NP) stage 1 palliation (S1P) and between S1P and stage 2 palliation (S2P). Standardized management of these patients may help to control hospital mortality. Aim of the study was to evaluate the impact on hospital mortality of a standardized perioperative management (SPM) for newborns requiring S1P in a low volume center for NP. METHODS: A consecutive series of patients undergoing S1P from January 1, 2002 to December 31, 2006 were retrospectively compared, by a "before and after" design, with those receiving a SPM (i.e. use of selective cerebral perfusion, near infrared spectroscopy, delayed sternal closure, modified ultrafiltration) from January 1, 2007 to December 31, 2018. Demographic, intraoperative and postoperative characteristics were collected. Univariate and multivariate analyses assessed differences before and after SPM. RESULTS: 91 newborns underwent S1P in the considered period; of 74 eligible patients, 25 didn't receive SPM, while 49 received SPM. Hospital mortality after S1P was 31% (CI 21-44%). The introduction of a SPM didn't affect hospital mortality both at the univariate (28% vs 29%, p = 0,959) and at the multivariate analysis (HR 1.85, p=0.62). Mortality was 12% (CI 6-25%) between hospital discharge after S1P and S2P and 8% (CI 3-22%) between S2P and S3P. CONCLUSIONS: The use of a SPM for HLHS newborns requiring S1P was not effective in reducing hospital mortality in a low volume center. We suggest a collaboration between Italian Pediatric Cardiac Centers to manage HLHS patients.

The optimum initial pediatric epidural bolus: a comparison of four local anesthetic solutions.

BACKGROUND: There is no consensus on the concentration or type of local anesthetic used for initiation of epidural anesthesia. The aim of this randomized, double-blind, controlled trial was to compare the clinical effectiveness of epidural administration of both levobupivacaine and bupivacaine in 0.2% and 0.25% concentrations in pediatric patients undergoing abdominal and urological surgery. METHODS: One hundred and forty-one children scheduled for lower abdominal and urological surgery were randomized to receive 0.4-0.6 ml.kg(-1) epidural, 0.25% bupivacaine, 0.2% bupivacaine, 0.25% levobupivacaine or 0.2% levobupivacaine. Initial epidural volumes, onset times; hemodynamic consequences, postoperative pain scores and degree of residual postoperative motor block were all recorded. RESULTS: There were no significant differences in the proportion of children with effective analgesia after incision [0.20% bupivacaine 97%, 0.25% bupivacaine 94%, 0.20% levobupivacaine 91%, 0.25% levobupivacaine 92% (P=0.73)] when a median volume of 0.55 ml.kg(-1) was used. There was no association between the volume used for thoracic, lumbar, or sacral epidural anesthesia and the effectiveness of the agents used. There was a significantly greater incidence of pain on awakening with the 0.2% solutions compared with the 0.25% solutions, but no differences in the incidence of residual motor block between groups. CONCLUSIONS: While there is no difference in the proportion of effective surgical anesthesia, the lower incidence of pain and distress with the 0.25% solutions suggests that this concentration has clinical advantages over the 0.2% solutions for pediatric epidural anesthesia.
