Brief Summary
Neostigmine is commonly used for medical treatment of acute colonic pseudo obstruction, however, the ideal route of administration has not been determined. Though IV push works rapidly, it is likely associated with the most side effects. This study will compare the efficacy and side effect profile of 2 potential routes of administration: IV push and subcutaneous.
