The carbon footprint and wastage of intravitreal injections.

Purpose: The healthcare system emits greenhouse gas emissions and produces waste that in turn threatens the health of populations. The objective of our study was to measure the ecological threat related to intravitreal injections.

Methods: Emissions were separated into scope 2 corresponding to Heating, Ventilation and Air Conditioning (HVAC) of the building, and scope 3 corresponding to travels (patients and staff), and life cycle assessment (LCA) of medical devices (MD) and pharmaceutics.

Is it safe to use telephone for anaesthesia consultation in high-risk patients before non-invasive surgery? A pilot study in ophthalmology.

Background: Although telemedicine with video support for preoperative evaluation has been found effective, there is limited research on anaesthesia consultation by phone without video support, particularly among high-risk patients. To evaluate the effectiveness, safety and potential benefits of performing pre-anaesthesia evaluation by phone before eye surgery in patients having non-invasive surgery, we performed an observational study in a French teaching hospital.

Method: All elective patients having elective ophthalmic surgery were included to have a consultation by phone instead of an in-person consultation, regardless of the type of anaesthesia or ASA score.

Investigating pupillometry to detect preoperative anxiety: a pilot study.

Guidelines from the European Society of Anesthesia (ESA) insist on the importance of preoperative anxiety management. However, its assessment currently relies on questionnaires that are long to submit and sometimes difficult to interpret. Exploring the balance between sympathetic and parasympathetic neural systems through the use of pupillometry is a promising path to identify anxiety and thus provides an objective and reproducible assessment tool.
