Balanced electrolyte solution with 1% glucose as intraoperative maintenance fluid in infants: a prospective study of glucose, electrolyte, and acid-base homeostasis.

Background: Optimal composition and infusion rates of intravenous maintenance fluids for children undergoing surgery are not well defined. Avoidance of hypoglycaemia, ketosis, and hyponatraemia is important, and current guidelines recommend isotonic fluids containing 1.0-2.

Preoperative fasting in children. The evolution of recommendations and guidelines, and the underlying evidence.

This review discusses the evolution of preoperative fasting guidelines and examines the incidence of pulmonary aspiration of gastric contents and suggested treatments. Nine guidelines developed by professional societies and published in peer-reviewed journals since 1994 were identified. The recommendations on preoperative fasting for various categories have undergone only small adaptations in the following three decades in pediatric anesthesia.

New methods needed to investigate the potential adverse effects of anaesthesia on neurological development in childhood.

The issue of potentially harmful effects of neurotoxicity or anaesthesia management on children undergoing general anaesthesia is still not resolved. Studies have so far been limited by methodological problems. In a retrospective cohort study, a new noninvasive method was used to demonstrate visual processing changes in children with a single previous exposure to anaesthesia.

Distribution and outcomes of paediatric anaesthesia services in Sweden: an epidemiological study.

Background: Centralisation of perioperative care for small children to a limited number of specialised paediatric centres has many theoretical advantages, but neither the optimal balance nor the current distribution of paediatric anaesthesia on a national scale are well elucidated. The aim of this study was to describe the distribution, adverse events, and mortality in children undergoing anaesthesia in Sweden.

Methods: In this cohort study, data from all paediatric anaesthesia procedures registered in Sweden during the years 2019-22 were extracted from the Swedish Perioperative Register (SPOR).

Paediatric postoperative acute kidney injury after non-cardiac surgery: Protocol for a systematic review and meta-analysis.

Background: Paediatric acute kidney injury (AKI) is associated with significant adverse outcomes such as increased mortality, progression to chronic kidney disease and longer length of stay in hospital. Postoperative AKI is a common and recognized complication after surgery in adults. In the paediatric population, AKI postoperatively to cardiac surgery has been extensively studied.

A Transfusion Regimen With Same-donor Packed Red Blood Cells Reduces Exposure to Multiple Blood Donors in Craniosynostosis Surgery.

In major craniosynostosis surgery with moderate to severe blood loss, patients may be exposed to multiple donors. We have previously reported a method for reducing donor exposure using mixed pediatric units including plasma. To further reduce donor exposure, we used plasma-free divided pediatric units.

Case series of peripherally inserted central catheter insertion in young children: A new approach to the axillary vein.

Background: We have developed a new approach for peripherally inserted central catheter (PICC) insertion that we think has several advantages, including ease of insertion, access to a larger vein and patient comfort.

Methods: In this case series report, the first 19 cases were audited.

Results: All PICCs were inserted without complications; 17 on the first attempt.

Lung impedance changes during awake prone positioning in COVID-19. A non-randomized cross-over study.

Background: The effects of awake prone positioning (APP) on respiratory mechanics in patients with COVID-19 are not well characterized. The aim of this study was to investigate changes of global and regional lung volumes during APP compared with the supine position using electrical lung impedance tomography (EIT) in patients with hypoxemic respiratory failure due to COVID-19.

Materials And Methods: This exploratory non-randomized cross-over study was conducted at two university hospitals in Sweden between January and May 2021.

Effects of caloric and nutrient content of oral fluids on gastric emptying in volunteers: a randomised crossover study.

Background: Previous studies demonstrated conflicting results regarding the determinants of gastric emptying for fluids. Our aim was to compare gastric emptying times of fluids with different caloric and nutrient content.

Methods: Healthy adult volunteers underwent gastric ultrasound assessment for 4 h after consuming beverages with different caloric and nutrient content using a crossover design (oat drink with 3% fat [310 kcal], mango juice [310 kcal], oat drink with 0.

Clear rules for clear fluids fasting in children.

Preoperative fasting guidelines published in 2022 by the European Society of Anaesthesiology and Intensive Care represent a paradigm shift in the preoperative preparation of children undergoing general anaesthesia. Schmitz and colleagues report the results from a multi-institutional prospective cohort study to determine if application of the recent guidelines increased the risk of regurgitation and pulmonary aspiration. This study provides support for the concept of reducing real fasting times by allowing clear fluids until 1 h before induction of anaesthesia.

Ephedrine to treat intraoperative hypotension in infants: what is the target?

Off-label use of medications in paediatric anaesthesia is common practice, owing to the relative paucity of evidence-based dosing regimens in children. Well-performed dose-finding studies, especially in infants, are rare and urgently needed. Unanticipated effects can result when paediatric dosing is based on adult parameters or local traditions.

Randomized cross-over study investigating the tolerability and side effects of an intra-oral air-cooling device compared to ice in healthy volunteers.

Oral cryotherapy (OC) is a common preventive treatment of oral mucositis (OM) and is recommended in international guidelines. Ice and air OC have previously been shown to result in temperature reductions of 8.1-12.

Effect of high-flow nasal oxygen on postoperative oxygenation in obese patients: A randomized controlled trial.

Background And Aim: Postoperative hypoxemia is common after general anesthesia in obese patients. We investigated if early application of high-flow nasal oxygen (HFNO) improved postoperative oxygenation in obese patients compared with standard oxygen therapy following general anesthesia for laparoscopic bariatric surgery.

Methods: This was an open labeled randomized controlled trial conducted at a university hospital in Sweden between October 23, 2018 and February 11, 2020.

Role of Renal Sympathetic Nerve Activity in Volatile Anesthesia's Effect on Renal Excretory Function.

Regulation of fluid balance is pivotal during surgery and anesthesia and affects patient morbidity, mortality, and hospital length of stay. Retention of sodium and water is known to occur during surgery but the mechanisms are poorly defined. In this study, we explore how the volatile anesthetic sevoflurane influences renal function by affecting renal sympathetic nerve activity (RSNA).

Pro-Con Debate: 1- vs 2-Hour Fast for Clear Liquids Before Anesthesia in Children.

Perioperative fasting guidelines are designed to minimize the risk of pulmonary aspiration of gastrointestinal contents. The current recommendations from the American Society of Anesthesiologists (ASA) and the European Society of Anaesthesiology and Intensive Care (ESAIC) are for a minimum 2-hour fast after ingestion of clear liquids before general anesthesia, regional anesthesia, or procedural sedation and analgesia. Nonetheless, in children, fasting guidelines also have consequences as regards to child and parent satisfaction, hemodynamic stability, the ability to achieve vascular access, and perioperative energy balance.

High-flow nasal cannula versus face mask for preoxygenation in obese patients: A randomised controlled trial.

Background: Preoxygenation efficacy with high-flow nasal cannula (HFNC) in obese patients is not clearly established. The primary aim of this study was to compare heated, humidified, high-flow nasal cannula with face mask for preoxygenation in this population.

Methods: We conducted a single-centre, randomised, controlled trial.

Awake prone positioning in patients with hypoxemic respiratory failure due to COVID-19: the PROFLO multicenter randomized clinical trial.

Background: The effect of awake prone positioning on intubation rates is not established. The aim of this trial was to investigate if a protocol for awake prone positioning reduces the rate of endotracheal intubation compared with standard care among patients with moderate to severe hypoxemic respiratory failure due to COVID-19.

Methods: We conducted a multicenter randomized clinical trial.
