In the Nova Scotia (NS) PD Program, patients are counseled to maintain a type 3-4 stool on the Bristol Stool Chart (BSC). An ideal stool is a type 4, which appears like a sausage or snake and is smooth and soft in consistency. To maintain a type 3-4 stool, current therapy includes senna 8.6-17.2 g twice daily with the addition of lactulose 30-60 mL twice daily, as needed. Rescue therapy in the Current Bowel Protocol is lactulose 30-60 mL every hour until bowel movement.
