The National Health Service (NHS) has pledged to reach carbon net-zero by 2040. In alignment with this goal, a London hospital's anaesthesia department is actively reducing desflurane use and transitioning towards total intravenous anaesthesia (TIVA) as a sustainable alternative, contributing to environmentally responsible practices within the healthcare sector. ⋯ The evaluation examines stakeholder attitudes, perceptions, and behaviours, focusing on transitioning from desflurane to TIVA. The study highlights the importance of staff engagement, organisational support, and underscores the crucial role that healthcare practitioners and leadership play in fostering sustainability within the healthcare sector.

Observational Study
Effects of intraoperative different fluid therapy protocols on postoperative renal functions.
Planning intraoperative fluid therapy in patients undergoing major abdominal surgery is important. It was aimed to define the difference between fluid therapy protocols for renal function, bleeding and postoperative service follow-ups. ⋯ Kidney function was preserved during individualized targeted fluid therapy using non-invasive haemodynamic monitoring parameters.

Acute kidney injury (AKI) significantly increases morbidity and mortality following cardiac surgery, especially in patients with pre-existing renal impairments. N-terminal pro-B-type natriuretic peptide (NT-proBNP) is a marker of cardiac stress and dysfunction, conditions often exacerbated during cardiac surgery and prevalent in chronic kidney disease (CKD) patients. Elevated NT-proBNP levels can indicate underlying cardiac strain, hemodynamic instability and volume overload. This study evaluated the association between perioperative changes in NT-proBNP levels and the incidence of AKI in this particular patient group. ⋯ Perioperative NT-proBNP level changes are predictive of postoperative AKI in patients with pre-existing renal deficiencies undergoing cardiac surgery, aiding in risk assessment and patient management.

The most commonly prescribed anti-seizures medications (ASMs) for the treatment of epilepsy are currently topiramate, zonisamide, lacosamide, carbamazepine and levetiracetam. The objective of this study was to examine the correlation between preoperative, intraoperative, and postoperative metabolic acidosis and the use of ASMs prior to craniotomy operations. ⋯ The use of ASMs in patients undergoing surgery is important in terms of mortality and morbidity. Topirimat and zonisamide are ASMs that can cause preoperative, intraoperative and postoperative metabolic acidosis. Patients receiving topirimat or zonisamide are particularly susceptible to metabolic acidosis. Special care should be taken in the management of anaesthesia in patients receiving these drugs, and monitoring of the perioperative metabolic status is essential.

Randomized Controlled Trial
90% effective volume of 0.1% ropivacaine combined with 0.4 µg/ml sufentanil for epidural labour analgesia with push pump at a rate of 400 mL/hr and a bolus interval of 30 min: a double-blind sequential dose-finding study.
It was reported that either shorter programmed intermittent epidural bolus (PIEB) intervals or high-speed bolus can produce more extensive epidural spread. We hypothesized that a combination of shortened time interval and increased speed of epidural bolus might further improve analgesic effect and therefore reduce the hourly volume for epidural labour analgesia. ⋯ The optimum bolus volume of ropivacaine with sufentanil while using push pump at a time interval of 30 min is approximately 5 mL. It could probably further reduce the hourly bolus volume for epidural labour analgesia.
