Carbon Footprint in Anesthetic Clinical Trial
Official title:
Life Cycle Assessment of General Anesthetic, Regional Anesthetic and the Combination of General Anesthetic and Regional Anesthetic: a Randomized Controlled Trial
Following Ethics approval, all adult patients undergoing surgery to fix the wrist fracture will be approached and consent to undergo this study. The amount of waste generated from general anesthetic, regional anesthetic and regional+general anesthetic will be collected and weighed. Patients undergoing this type of wrist surgery have only regional anesthetic, or general anesthetic, or both ie. regional anesthetic and general anesthetic. The aim of the study is to compare the amount of waste generated from each type of anesthetic and this will give us a better idea of which anesthetic is more environmentally sustainable.
Following Ethics approval, all adult patients undergoing surgery to fix the wrist fracture will be approached and consent to undergo this study. The amount of waste generated from general anesthetic, regional anesthetic and regional+general anesthetic will be collected and weighed. Waste will include disposable and reusable wastes. Examples of disposable waste are all plastic packaging, syringes, needles, breathing tube, breathing circuits, gloves as well as drugs. Examples of reusable waste will be anesthetic face mask, laryngeal mask (which is a form of airway device that can be reprocessed), sterile gowns. The amount of anesthetic gas used will be obtained from the anesthetic machine. Patients undergoing this type of wrist surgery have only regional anesthetic (freezing performed higher up in the arm to numb the whole arm for several hours), or general anesthetic (patient completely goes to deep anesthetic sleep), or both ie. regional anesthetic (freezing just for pain control afterwards) and general anesthetic (patient goes to deep anesthetic sleep after the freezing is done and they may need less pain killer during the surgery as well as afterwards). The amount of waste generated will be compared amongst these 3 groups by life cycle analysis. ;
