The two most common methods for ultrasound-guided arterial cannulation are the long-axis in-plane (LA-IP) and short-axis out-of-plane (SA-OOP) approaches. However, it is uncertain which method is more advantageous. We conducted a meta-analysis of reported randomized clinical trials (RCTs) comparing the two techniques in terms of success rate, cannulation time, and complications. ⋯ The present results suggest that the SA-OOP technique is associated with a higher incidence of posterior wall puncture and hematoma than the LA-IP technique, whereas success rates are similar for the two ultrasound-guided arterial cannulation techniques. These findings should be experimentally evaluated in a more rigorous manner due to high inter-RCT heterogeneity.

Clinical Trial
Changes in ventilation distribution during general anesthesia measured with EIT in mechanically ventilated small children.
Atelectasis during general anesthesia is a risk for perioperative complications. EIT measurements were performed in mechanically ventilated healthy children during elective surgery to demonstrate the changes in ventilation distribution during general anesthesia. The ventilation distribution was quantified by calculating the Global Inhomogeneity index (GI). ⋯ Controlled ventilation of healthy children resulted in increased ventilation of the ventral and collapse of the dorsal lung areas. Restart of spontaneous breathing after cessation of surgery resulted in an increase in ventilation in the dorsal with decrease in the ventral lung areas. By calculating the GI, representing the ratio of more to less ventilated lung areas, revealed the presumed homogeneous distribution of ventilation.

Observational Study
Glycaemic profile of children undergoing anaesthesia (GLYCANA) at Mercy James Centre in Malawi: an observational study.
Hypoglycaemia and hyperglycaemia may develop during anaesthesia and surgery in children and can lead to severe adverse clinical outcomes. No study, as far as we know, has investigated glucose homeostasis in children undergoing surgery in Malawi. The aim of this study was to assess perioperative glucose levels of the children undergoing anaesthesia at Mercy James Centre (MJC) for Paediatric Surgery, Blantyre, Malawi. ⋯ Glycaemia increases under anaesthesia and surgery. Recommended fasting times, optimising nutritional status, when possible, no dextrose or lower than 2.5% dextrose in IV maintenance fluid are possible strategies to maintain blood sugar homeostasis during paediatric surgery and anaesthesia.

Observational Study
Persistent incisional pain at 1 year after craniotomy: a retrospective observational study.
There have been few reports on persistent incisional pain at 1 year after craniotomy. Hence, this study aimed to explore the distribution of pain at 1 year after elective craniotomy and its related factors. ⋯ The pain score at 1 year after elective craniotomy was minor; however, preoperative bodily pain and postoperative pain scores were significantly related factors.
