AbstractAlthough the hazards of using Demerol for pain management is well documented, physicians at a 350-bed tertiary-care center in the upper midwest continued to follow the antiquated practice of ordering intramuscular Demerol and Vistaril to manage pain for patients with acute pancreatitis. Their reasoning was based on early evidence that Demerol, unlike morphine, does not cause biliary-tract spasms resulting in epigastric or right upper quadrant pain. In an effort to change practice patterns, a multidisciplinary team was formed to study the efficacy of using Transdermal Therapeutic System (TTS) fentanyl to manage pain in this patient population. Thirty-two subjects were enrolled in a double-blind, placebo-controlled study to evaluate the efficacy of using TTS fentanyl with intramuscular Demerol for breakthrough pain in comparison to using a placebo system and intramuscular Demerol. There was no statistically significant difference in self-reported pain intensity between the control and experimental groups on the first day of hospitalization. This finding would be expected because serum fentanyl concentrations rise gradually during the first 12 to 14 hours after application of the TTS fentanyl and plateau at 24 hours. There was a statistically significant difference between groups at 36 hours (exact p <.0154) and 45 hours (exact p <.0132) after application of the TTS fentanyl. This is probably because of greater serum fentanyl concentrations observed during the 36- to 48-hour period after application of TTS fentanyl. Although not statistically significant, trends in the data revealed that the experimental group had lower self-reported pain intensity scores than the control group throughout the course of hospitalization. Even though the experimental group had significantly more previous hospitalizations for acute pancreatitis and a higher pain intensity score on admission, this group had a significantly shorter length of stay in the hospital c2 (1, N = 31) = 4.3706 p <.05. There was no statistically significant difference between the two groups for self-reported satisfaction with pain management.Copyright 2002, Elsevier Science (USA). All rights reserved.
