Pharmaceuticals account for 19-32% of healthcare greenhouse gas (GHG) emissions. Paracetamol is a common perioperative analgesic agent. We estimated GHG emissions associated with i.v. and oral formulations of paracetamol used in the perioperative period. ⋯ Intravenous paracetamol has 12-fold greater life-cycle carbon emissions than the oral tablet form. Glass vials have higher greenhouse gas emissions than plastic vials. Intravenous administration should be reserved for cases in which oral formulations are not feasible.

Anaesthesia contributes substantially to the environmental impact of healthcare. To reduce the ecological footprint of anaesthesia, a set of sustainability interventions was implemented in the University Hospital Zurich, Switzerland. This study evaluates the environmental and economic implications of these interventions. ⋯ Implementing sustainable anaesthesia interventions can significantly reduce the environmental impact and cost of anaesthesia.

Review Meta Analysis
The effect of sugammadex on patient morbidity and quality of recovery after general anaesthesia: a systematic review and meta-analysis.
Residual neuromuscular block is associated with increased patient morbidity. Therefore prevention of residual neuromuscular block is an important component of general anaesthesia where neuromuscular blocking agents are used. Whereas sugammadex improves reversal based on neuromuscular twitch monitoring parameters, there have been no prospective, adequately powered definitive studies demonstrating that sugammadex is also associated with less patient morbidity. ⋯ PROSPERO database (CRD42022325858).

The microcirculation describes the network of the smallest vessels in our cardiovascular system. On a microcirculatory level, oxygen delivery is determined by the flow of oxygen-carrying red blood cells in a given single capillary (capillary red blood cell flow) and the density of the capillary network in a given tissue volume (capillary vessel density). Handheld vital videomicroscopy enables visualisation of the capillary bed on the surface of organs and tissues but currently is only used for research. ⋯ Similarly, it remains unclear if cardiac surgery, especially with cardiopulmonary bypass, impairs the sublingual microcirculation. The effects of therapeutic interventions specifically targeting the microcirculation remain to be elucidated and tested. Future research should focus on further improving microcirculation monitoring methods and investigating how regional microcirculation monitoring can inform clinical decision-making and treatment.
