Abstract
Introduction: The most effective treatment for withdrawal syndrome in Opioid-dependent patients admitted to intensive care units (ICUs) remains unknown. This study aimed to compare fentanyl and methadone in this regard.
Methods: This prospective, single-blinded, controlled pilot study was conducted on opioid-dependent intubated patients admitted to the toxicology ICU of Loghman Hakim Hospital, Tehran, Iran, between August 2019 and August 2020. Patients were alternately assigned to either fentanyl or methadone group after the initiation of their withdrawal syndrome. Duration and alleviation of the withdrawal signs and symptoms, ICU and hospital stay, development of complications, development of later signs/symptoms of withdrawal syndrome, and need for further administration of sedatives to treat agitation were then compared between these two groups.
Results: Median age of the patients was 42 [interquartile range (IQR): 26, 56]. The two groups were similar in terms of the patients’ age (p = 0.92), sex (p = 0.632), primary Simplified Acute Physiology Score (SAPS) II (p = 0.861), and Clinical Opiate Withdrawal Score (COWS) before (p = 0.537) and 120 minutes after treatment (p = 0.136) with either methadone or fentanyl. The duration of intubation (p = 0.120), and ICU stay (p = 0.572), were also similar between the two groups. The only factor that was significantly different between the two groups was the time needed for alleviation of the withdrawal signs and symptoms after the administration of the medication, which was significantly shorter in the methadone group (30 vs. 120 minutes, p = 0.007).
Conclusion: It seems that methadone treats the withdrawal signs and symptoms faster in dependent patients. However, these drugs are similarly powerful in controlling the withdrawal signs in these patients.
