European Society of Anaesthesiology and Intensive Care consensus document on sustainability: 4 scopes to achieve a more sustainable practice.

Climate change is a defining issue for our generation. The carbon footprint of clinical practice accounts for 4.7% of European greenhouse gas emissions, with the European Union ranking as the third largest contributor to the global healthcare industry's carbon footprint, after the United States and China. Recognising the importance of urgent action, the European Society of Anaesthesiology and Intensive Care (ESAIC) adopted the Glasgow Declaration on Environmental Sustainability in June 2023. Building on this initiative, the ESAIC Sustainability Committee now presents a consensus document in perioperative sustainability. Acknowledging wider dimensions of sustainability, beyond the environmental one, the document recognizes healthcare professionals as cornerstones for sustainable care, and puts forward recommendations in four main areas: direct emissions, energy, supply chain and waste management, and psychological and self-care of healthcare professionals. Given the urgent need to cut global carbon emissions, and the scarcity of evidence-based literature on perioperative sustainability, our methodology is based on expert opinion recommendations. A total of 90 recommendations were drafted by 13 sustainability experts in anaesthesia in March 2023, then validated by 36 experts from 24 different countries in a two-step Delphi validation process in May and June 2023. To accommodate different possibilities for action in high- versus middle-income countries, an 80% agreement threshold was set to ease implementation of the recommendations Europe-wide. All recommendations surpassed the 80% agreement threshold in the first Delphi round, and 88 recommendations achieved an agreement >90% in the second round. Recommendations include the use of very low fresh gas flow, choice of anaesthetic drug, energy and water preserving measures, "5R" policies including choice of plastics and their disposal, and recommendations to keep a healthy work environment or on the importance of fatigue in clinical practice. Executive summaries of recommendations in areas 1, 2 and 3 are available as cognitive aids that can be made available for quick reference in the operating room.

Dexmedetomidine for the reduction of emergence delirium in children undergoing tonsillectomy with propofol anesthesia: A double-blind, randomized study.

BACKGROUND: Postanesthesia emergence delirium is a motor agitation state complicating pediatric anesthesia. We investigated the efficacy of dexmedetomidine in reducing emergence delirium in children undergoing tonsillectomy with and without adenoidectomy using total intravenous anesthesia with propofol. METHODS: This was a prospective, single-center, double-blind, randomized study. The primary outcome was the presence or absence of emergence delirium with and without dexmedetomidine. Secondary outcomes were emergence delirium severity, time to extubation, cardiovascular stability, and need for additional postoperative analgesia. Eligible were children 3-14 years of age, ASA I or II, scheduled for tonsillectomy with or without adenoidectomy. Patients were randomized to receive dexmedetomidine 1 mcg kg-1 or a volume matched normal saline solution. Presence of emergence delirium and agitation severity was assessed with the Watcha scale 10, 20, and 30 minutes after arrival in the postanesthesia care unit. RESULTS: Sixty children participated to the study, 31 (51.7%) of them were treated with dexmedetomidine. Their mean age was 6.2 years (SD 5.5). Duration of anesthesia and surgery and blood pressure measurements did not differ between groups. Extubation time was not different between groups. The dexmedetomidine group had a significantly lower frequency of emergence delirium compared with no dexmedetomidine after 20 and 30 minutes in postanesthesia care unit: 16.1% and 12.9% at 20 and 30 minutes in the dexmedetomidine group vs 48.3% and 41.4% in in the no dexmedetomidine group. CONCLUSION: Dexmedetomidine 1 mcg kg-1 reduces the incidence and severity of emergence delirium after tonsillectomy with propofol anesthesia without prolonging the extubation time.

The child with glutaric aciduria type I: anesthetic and perioperative management.

Glutaric aciduria type I (GA-1) is an inborn error of metabolism caused by a deficiency of glutaryl-CoA dehydrogenase. It presents early in life, usually after an episode of fever, dehydration, infection or fasting, and results in metabolic decompensation and neurologic damage. We report the perioperative management of a 5-year-old boy admitted to the hospital for surgery because of neurogenic hip dislocation. Here we present the preoperative preparation, which focused on appropriate fluid administration and therapy intensification, as well as the safe anesthetic management with inhalation anesthesia and remifentanil, taking into consideration the mitochondrial basis of the disease. Furthermore, the role of postoperative care is emphasized in relation to stress response prophylaxis and the avoidance of complications related to the disorder.
