简要总结
The purpose of this research is to study the effect of cannabis (marijuana) on gastric (stomach) emptying before surgery. The study will include people who use cannabis (study group) and people who do not use cannabis (control group).
详细描述
About 108 people will take part in this study (54 in the study group and 54 in the control group). Subjects will have an ultrasound of the abdomen before their scheduled surgery. The ultrasound will determine how much fluid remains in the abdomen.
Researchers will also review subjects' medical records and will include: age, body mass index, history of cannabis use including how often and how consumed, reason for surgery, and length of time without eating before surgery.
