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.

There is well-established evidence linking adverse childhood experiences (ACEs) and chronic pain in adulthood. It is less clear how ACE exposure might influence the response to chronic pain treatment. In this systematic review, we synthesise the literature assessing the impact of ACE exposure on outcomes relating to the use, benefits, and harms of analgesic medications (analgesia-related outcomes). ⋯ CRD42023389870 (PROSPERO).

Cardiac surgery poses a significant risk of perioperative bleeding and allogeneic blood transfusions, particularly in patients with bleeding disorders. Increasingly frequent use of coagulation factor concentrates could impact haemorrhagic risks, thromboembolic events, and costs. We describe the use of coagulation factor concentrates and allogeneic blood products in cardiac surgical patients with hereditary and acquired bleeding disorders to assess pertinent outcomes, including perioperative haemorrhage, thromboembolism, and hospital costs. ⋯ Acquired bleeding disorders in cardiac surgery patients are associated with increased use of haemostatic interventions, postoperative complications, and increased healthcare costs. Improved management of perioperative haemostasis and thromboprophylaxis strategies are essential for optimising patient outcomes and reducing expenses.
