Postoperative anxiety and depression can negatively affect surgical outcomes and patient wellbeing. This study aimed to quantify the incidence of postoperative worsening anxiety and depression symptoms and to identify preoperative predictors of these conditions. ⋯ Postoperative worsening anxiety and depression appear to be associated more closely with preoperative active mental health or pain symptoms rather than self-reported history of these conditions. Preoperative identification of at-risk patients will require screening for symptoms rather than simple history taking.

Flexible bronchoscopy for tracheal intubation is indicated in patients with difficult airways, but the upper airway is frequently obstructed in sedated or anaesthetised apnoeic patients. This makes it more difficult to locate the glottis through bronchoscopy, and increases the risk of hypoxaemia. Nasal high-flow oxygenation is useful to prevent hypoxaemia during airway management, but no studies have assessed if this method of oxygenation improves the bronchoscopic view of the glottis by preventing upper airway obstruction. ⋯ Nasal high-flow oxygenation facilitates flexible bronchoscopy for tracheal intubation by widening the pharyngeal space and by improving the view of the glottis through the bronchoscope. Therefore, use of nasal high-flow oxygenation is useful in patients with difficult airways in whom flexible bronchoscopy for tracheal intubation is indicated.

Delayed gastric emptying increases the risk of pulmonary aspiration during anaesthesia for Caesarean delivery. Our aim in conducting this narrative review was to consider the effect of pregnancy on gastric emptying. The indices of gastric emptying after liquids, solids, or both and when fasted in the various trimesters of pregnancy, at the time of Caesarean delivery, in labour, and the postpartum period were assessed. ⋯ Women in labour who have eaten solids in the last 8 h still have high-risk gastric contents present in the stomach. The evidence with respect to the postpartum period is conflicting. In conclusion, inconsistencies in the literature reflect the unpredictability of gastric emptying in pregnancy and underline the potential value of gastric ultrasound in women who are pregnant.

Concerns regarding residual neuromuscular block (RNMB) have persisted since the introduction of neuromuscular blocking agents, with reported incidences in the 21st century up to 50%. Advances in neuromuscular transmission (NMT) monitoring and the introduction of sugammadex have addressed this issue, but the impact of these developments remains unclear. ⋯ The incidence of residual neuromuscular block in the PACU was 2.2%. This suggests significant improvement in the prevention of residual neuromuscular block and stresses the importance of rigorous neuromuscular transmission monitoring and adequate use of reversal agents.
