Pulmonary aspiration in the perioperative period carries the risk of significant morbidity and mortality. As such, guidelines have been developed with the hopes of minimizing this risk by recommending fasting from solids and liquids over a specified amount of time. Point-of-care ultrasound has altered the landscape of perioperative medicine; specifically, gastric ultrasound plays a pivotal role in perioperative assessment. Further, the advent of glucagon-like-peptide-1 receptor agonists, the widespread use of cannabis, and Enhanced Recovery program carbohydrate beverage presents new challenges when attempting to standardize fasting guidelines. This review synthesizes the literature surrounding perioperative fasting guidelines specifically with regard to the use of point-of-care ultrasound in assessing for gastric contents and minimizing the risk of aspiration.

A female teenager with a history of polysubstance use, including a recent overdose, is scheduled for multilevel posterior spinal fusion surgery due to idiopathic scoliosis and has asked to avoid the use of opioids in the context of her upcoming surgery. This problem-based learning discussion (PBLD) focuses on the examination of the care of a spinal fusion patient that allowed for the successful provision of opioid-obviating care.
