Review Meta AnalysisPatient-Controlled Analgesia Plus Background Opioid Infusion for Postoperative Pain in Children: A Systematic Review and Meta-Analysis of Randomized Trials.
Bolus administration of opioids via a patient-controlled analgesia (PCA) device is widely used in the postoperative pediatric population. PCA devices have been shown to provide superior analgesia and greater patient satisfaction compared with intermittent administration. Studies comparing the efficacy of PCA with and without a background infusion for postoperative analgesia in children vary considerably in terms of dosing and methodologic quality, making it difficult for practitioners to derive clinically useful information. The purpose of this meta-analysis was to assess whether the addition of a background infusion to PCA bolus administration of an opioid analgesic is more effective (defined as lower pain scores) than PCA bolus alone in the postoperative population specific to children. ⋯ There was no significant difference in outcomes with the addition of an opioid background infusion to PCA bolus doses of opioid. Further high-quality studies are required.

Review Meta Analysis Comparative StudyDoes Propofol Anesthesia Lead to Less Postoperative Pain Compared With Inhalational Anesthesia?: A Systematic Review and Meta-analysis.
Many studies have compared propofol-based anesthesia with inhalational anesthesia. Results from several studies have shown improved postoperative analgesia after propofol anesthesia, but other studies showed contradictory results. There are no large prospective studies that compare postoperative pain after propofol versus inhalational anesthesia. This meta-analysis was designed to focus on this question. ⋯ The current results are affected by substantial heterogeneity, which makes it difficult to predict significant differences in postoperative pain control between propofol anesthesia and inhalational anesthesia. Further large, randomized controlled trials are needed to corroborate these results and to detect differences (if any) between propofol and inhalational anesthesia on postoperative pain.

Clinical Trial Observational StudyThe Feasibility of a Completely Automated Total IV Anesthesia Drug Delivery System for Cardiac Surgery.
In this pilot study, we tested a novel automatic anesthesia system for closed-loop administration of IV anesthesia drugs for cardiac surgical procedures with cardiopulmonary bypass. This anesthesia drug delivery robot integrates all 3 components of general anesthesia: hypnosis, analgesia, and muscle relaxation. ⋯ The completely automated closed-loop system tested in this investigation could be used successfully and safely for cardiac surgery necessitating cardiopulmonary bypass. The results of the present trial showed satisfactory clinical performance of anesthesia control.

Development and Validation of a Risk Stratification Score for Children With Congenital Heart Disease Undergoing Noncardiac Surgery.
Children with major and severe congenital heart disease (CHD) undergoing noncardiac surgery are at increased risk of mortality. The objective of this study was to identify the predictors for in-hospital mortality, and to develop a risk stratification score that could be used to help decision making and the development of perioperative management guidelines. ⋯ Our study demonstrates that, in addition to preoperative markers of critical illness (eg, inotropic support, mechanical ventilation, preoperative cardiopulmonary resuscitation, and acute or chronic kidney injury), the type of lesion (eg, single-ventricle physiology) and the functional severity of the heart disease (eg, severe CHD) are strong predictors of in-hospital mortality in children undergoing noncardiac surgery.
