RANDOMIZED CONTROLLED TRIAL
Sedation for Endoscopic Retrograde Cholangiopancreatography in Elderly Patients - the Effect of Intravenous Lidocaine Infusion. A Randomised, Double-Blind, Placebo Controlled Trial.
Journal of Gastrointestinal and Liver Diseases : JGLD 2022 December 18
BACKGROUND: Sedation of elderly patients with associated comorbidities, subjected to ERCP procedure, can produce serious complications including respiratory instability and hemodynamics caused by the administration of anesthetic substances. In this study we aimed to evaluate whether the administration of lidocaine in continuous infusion during ERCP procedure reduces the consumption of propofol and the rate of complications in these patients.
METHODS: 83 patients over 65-year old, ASA II-IV score, undergoing an ERCP procedure were randomized in two groups: lidocaine group (group L) who received 1.5 mg/kg lidocaine 1% and propofol 1mg/kg at induction and then 2 mg/kg lidocaine 1% in continuous infusion during the procedure and control group (group C) who received saline in the same amount as group L and propofol 1mg/kg. The consumption of propofol, intraprocedural complications, the time of awakening and recovery, the quality of postprocedural analgesia, the satisfaction of the endoscopist were registered.
RESULTS: Propofol consumption was statistically significantly lower in group L compared to group C [135.37 (±43.23) vs. 214.88 (±51.83), p=0.001]. The same result was obtained related to the awakening time [2.85 (±1.50) vs. 5.38 (±1.36), p=0.001] and recovery time [23.90 (±12.66) vs. 26.17 (±12.41), p<0.001], the episodes of intraprocedural desaturation (p=0.001), the involuntary intraprocedural movements (p=0.001), the endoscopist's satisfaction (p=0.006). No differences were found in terms of post-procedure pain scores (p=0.54).
CONCLUSIONS: Lidocaine can be administered to reduce the need for propofol, faster awakening and lower intraprocedural complications in elderly patients undergoing the ERCP procedure.
