Randomized Controlled Trial
Effect of pre-operative oral paracetamol on gastric residual volume and pH in young children in the context of a 1-hour clear fluid fast: a randomised controlled trial.
High gastric residual volume and low pH are associated with increased mortality following pulmonary aspiration in animal studies. The use of pre-operative oral paracetamol has not been investigated in younger children and infants in the context of a prescriptive 1-h clear fluid fast aimed at reducing the risk of pulmonary aspiration while improving patient experience. Children aged 1 month up to a weight of 25 kg and scheduled for elective surgery were randomly allocated to receive a prescribed 3.6 ml.kg-1 drink of water alone (water group) or 3 ml.kg-1 water and oral Infant Calpol® syrup (24 mg.ml-1 concentration, equivalent volume 0.6 ml.kg-1 , paracetamol group) 1 h before the induction of anaesthesia. ⋯ There was no significant difference in gastric residual volume (p = 1) or pH (p = 0.99) between the water and the paracetamol groups. Sub-group analysis revealed no significant difference in gastric residual volume or pH for 29 children who weighed < 10 kg compared with > 10 kg. Using a prescriptive fluid regime of 3 ml.kg-1 of water, the addition of oral paracetamol syrup did not significantly alter gastric residual volume or pH in the context of a 1-h fast in infants and young children.

Randomized Controlled Trial Multicenter Study
Analgesia for major laparoscopic abdominal surgery: a randomised feasibility trial using intrathecal morphine.
Effective pain control enhances patient recovery after surgery. Laparoscopic techniques for major abdominal surgery are increasingly utilised to reduce surgical trauma. Intrathecal morphine is an attractive analgesic option that is gaining popularity. ⋯ For secondary endpoints, fewer patients in the intrathecal morphine group required opioids in the post-anaesthesia care unit, their postoperative pain scores at rest were lower across the four time-points measured (p = 0.007), but not dynamic pain scores (p = 0.061), and pruritus was more common following intrathecal morphine (p = 0.007). Total oral morphine equivalents until postoperative day 3 were less in the intrathecal morphine group (median (95%CI) difference 82 (-13 to 168) mg), but this reduction was not statistically significant (p = 0.10). These findings support conducting a definitive clinical trial.

Randomized Controlled Trial
'Dear Doctor': a randomised controlled trial of a text message intervention to reduce burnout in trainee anaesthetists.
One in four doctors in training in the UK reports feeling 'burnt out' due to their work and similar figures are reported in other countries. This two-group non-blinded randomised controlled trial aimed to determine if a novel text message intervention could reduce burnout and increase well-being in UK trainee anaesthetists. A total of 279 trainee anaesthetists (Core Training Year 2, Specialty Training Years 3 or 4) were included. ⋯ Exploratory post-hoc analysis found the intervention was associated with reduced burnout in participants reporting personal or work-related difficulties during the trial period (-9.56, -17.35 to -1.77, p = 0.02) and in participants reporting that the COVID-19 pandemic had a big negative impact on their well-being (-10.38, -20.57 to -0.19, p = 0.05). Overall, this trial found the intervention had no impact. However, given this intervention is low cost and requires minimal time commitment from recipients, it may warrant adaptation and further evaluation.

Randomized Controlled Trial
A randomised controlled trial of a novel tramadol chewable tablet: pharmacokinetics and tolerability in children.
Tramadol is a bitter atypical opioid analgesic drug and is prescribed to treat postoperative pain in children. However, in many countries there is no licensed paediatric tramadol formulation available. We have formulated a novel chewable chocolate-based drug delivery system for the administration of tramadol to children. ⋯ Larger inter-individual variability in absorption rates were observed with the liquid tramadol. The tramadol chewable tablet was more acceptable in taste to children when assessed by the children, parents and nurses (all p < 0.001). We conclude that the novel tramadol chewable tablet has favourable acceptability and more reliable relative bioavailability in children compared with tramadol hydrochloride oral liquid.
