简要总结
The aim of this study is to perform bedside gastric point of care ultrasound (POCUS) exams to assess the gastric volume and content (clear liquids vs solid food) perioperatively in patients who report cannabis use.
详细描述
Cannabis use in the United States has continued to increase in recent years, particularly in the adult population. Ease of access through legalization paired with improved public perception has contributed to the uptick in cannabis use. The subset of cannabis users suffering from pain who present for surgery pose a risk for perioperative aspiration due to the slowing of gastric motility due to cannabis use. There is currently no adapted NPO guideline to account for cannabis use.
Gastric Ultrasound (GUS) can be used as a bedside tool for assessing a patient's stomach contents and risk of aspiration. GUS can identify whether a patient's stomach is empty or filled with clear liquid, thick liquid, or solid food. The volume of the stomach can be accurately calculated if there is clear liquid content. A full stomach is categorized as those with solid or thick liquid content or with clear liquid measuring more than 1.5 ml/kg body weight. As GUS is noninvasive and does not pose risk to patients, it is a useful tool assessing aspiration risk in the preoperative period.

结局指标
主要结局
Incidence of delayed gastric emptying
时间窗: This will be measured pre-operatively in the holding room area.
A full stomach on gastric ultrasound is defined by the presence of either solid food, thick liquids, or a specific volume (\>1.5 ml/kg) of clear liquids on gastric ultrasound.
次要结局
- Nothing by mouth (NPO) intervals(This will be measured pre-operatively in the holding room area.)
- Time interval since last cannabis use(This will be measured pre-operatively in the holding room area.)
- Presence of gastric peristalsis(This will be measured pre-operatively in the holding room area.)
