Background:
Small bowel obstruction (SBO) is a common condition leading to numerous hospital admissions and operations. Standardized care of adhesive SBO patients has not been widely implemented in hospital systems.
Methods:
A prospective cohort of SBO patients was compared to a historical cohort of SBO patients after implementation of a SBO protocol using evidence-based guidelines and Omnipaque, a low-osmolar water soluble contrast. Patients without a history of abdominal surgery were excluded and data was collected through chart review.
Results:
Univariate analyses demonstrated a decrease in both LOS by 1.35 days and in the proportion of patients receiving surgery (37% vs 25%; p < 0.05). There was a decrease in time to surgery, rate of SBR, and rate of complications, yet an increase in readmission, although these findings were not statistically significant.
Conclusions:
Utilizing an evidence-based SBO protocol can lead to shorter LOS and may result in fewer operations for adhesive SBO patients.

Physical Properties Affecting Solubility
As for any solution, the solubility of a gas in a liquid is affected by the attractive intermolecular forces between solute and solvent species. Unlike solid and liquid solutes, however, there is no solute-solute intermolecular attraction to overcome when a gaseous solute dissolves in a liquid solvent since the atoms or molecules comprising a gas are far separated and experience negligible interactions. Consequently, solute-solvent interactions are the sole...
