Schauer %J Archive of "Pain and Therapy". %D 2017 %R 10.1007/s40122-016-0064-z %X Postoperative pain management can be challenging in patients with a high body mass index (BMI) especially as a result of poor venous access and delayed ambulation that can result in serious complications. Fentanyl iontophoretic transdermal system (ITS) is a needle-free, patient-controlled analgesic method available for use in acute postoperative pain. The primary objective of these analyses was to determine if there were any differences between patients with high BMI (>40 kg/m2) and lower BMIs (<30 kg/m2 and 35¨C40 kg/m2) in terms of efficacy or safety %K Fentanyl %K High body mass index %K Ionsys %K Iontophoretic transdermal system %K Obesity %K Patient-controlled analgesia %K Postoperative pain %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5447541/
