RT Journal Article SR Electronic T1 Can a bowel preparation exacerbate heart failure? JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 157 OP 160 DO 10.3949/ccjm.77a.10025 VO 78 IS 3 A1 Parikh, Kalindi A1 Weitz, Howard YR 2011 UL http://www.ccjm.org/content/78/3/157.abstract AB Polyethylene glycol solutions, used for bowel preparation before colonoscopy, in theory pass through the colon without any absorption of water. However, several investigators have reported that these solutions do increase plasma volume. This review compares polyethylene and sodium phosphate bowel preparations and their effects on patients with heart failure, and also offers recommendations for patients with heart failure who need colonoscopy.
