Postoperative free water administration is associated with dysnatremia after congenital heart disease surgery in infants.
Dysnatremia after congenital heart disease (CHD) surgery is common. European guidelines on intraoperative fluid therapy in children recommend isotonic solutions to avoid hyponatremia, but prolonged cardiopulmonary bypass and administration of high sodium-containing solutions (i.e., blood products and sodium bicarbonate) are associated with postoperative hypernatremia. The aim of the study was to describe fluid composition prior to and during the development of postoperative dysnatremia. ⋯ Postoperative hyponatremia occurred in 30% of infants despite restrictive volumes of hypotonic maintenance fluid, whereas hypernatremia was mainly associated with blood product transfusion. Individualized fluid therapy, with continuous reassessment to reduce the occurrence of postoperative dysnatremia is mandatory in pediatric cardiac surgery. Prospective studies to evaluate fluid therapy in pediatric cardiac surgery patients are warranted.

Review Meta AnalysisGlucocorticoids added to paracetamol and NSAIDs for postoperative pain: a systematic review with meta-analysis and Trial Sequential Analysis.
Paracetamol and non-steroidal anti-inflammatory drugs (NSAIDs) are recommended as the basic pain treatment regimen for most surgeries. Glucocorticoids have well-known anti-inflammatory and anti-emetic properties and may also demonstrate analgesic effects. We assessed benefit and harm of adding glucocorticoids to a combination of paracetamol and NSAIDs for post-operative pain management. ⋯ Multimodal approaches for post-operative analgesia are favoured, including paracetamol and nonsteroidal anti-inflammatory drugs. In this meta-analysis, pooled results from clinical trials are assessed to describe possible benefit of addition of glucocorticoid treatment for analgesia. The findings did not identify additional benefit, though the certainty of the evidence was not high.

Observational StudyThe Usefulness of a Nasopharyngeal Multiplex Polymerase Chain Reaction System to Screen Pediatric Patients with Preoperative Fever.
When children have a preoperative fever, anesthesiologists must help determine whether to postpone or proceed with surgery, as fever may be a sign of upper respiratory tract infection (URTI). Such infections are a known risk factor for perioperative respiratory adverse events (PRAEs), which are still one of the prime causes of anesthetic mortality and morbidity in pediatric patients. Since the COVID-19 pandemic, preoperative assessments have become drastically more complex as hospitals strive to balance practicality and safety. In our facility, if pediatric patients presented with preoperative fever, we used the FilmArray® Respiratory Panel 2.1 to determine whether to postpone or proceed with surgery. ⋯ Our retrospective observational study revealed that 44% of the FilmArray positive group subsequently developed symptoms, and no PRAEs were observed in the FilmArray negative group. We suggest that FilmArray could be useful as a screening test for pediatric patients with preoperative fever.

Randomized Controlled TrialComparing Restrictive vs. Liberal Oxygen Strategies for Trauma Patients: The TRAUMOX2 Trial - Statistical Analysis Plan.
The international advanced trauma life support guidelines recommend that all severely injured trauma patients receive supplemental oxygen based on very limited evidence. The TRAUMOX2 trial randomises adult trauma patients to a restrictive or liberal oxygen strategy for 8 h. The primary composite outcome consists of 30-day mortality and/or development of major respiratory complications (pneumonia and/or acute respiratory distress syndrome). This manuscript presents the statistical analysis plan for TRAUMOX2. ⋯ This statistical analysis plan of the TRAUMOX2 trial will minimise bias and add transparency to the statistics applied in the analysis of the trial. The results will add evidence on restrictive and liberal supplemental oxygen strategies for trauma patients.

Lower or Higher Oxygenation Targets for Acute Hypoxaemic Respiratory Failure: protocol for an individual patient data meta-analysis.
Supplemental oxygen therapy is central to the treatment of acute hypoxaemic respiratory failure, a condition which remains a major driver for morbidity and mortality in intensive care. Despite several large randomised clinical trials comparing a higher versus a lower oxygenation target for these patients, significant differences in study design impede analysis of aggregate data and final clinical recommendations. ⋯ The presented individual patient data meta-analysis will synthesise individual level patient data from two of the largest randomised clinical trials on targeted oxygen therapy in intensive care. The results will provide a re-analysis of the intervention effects on the pooled intention-to-treat populations and facilitate subgroup analyses with an increased power to detect clinically important effect modifications.
