Background And Aim:
The endoscopic retrograde cholangiopancreatography (ERCP) procedure is generally performed in patients with high comorbidity. We aimed to reduce the consumption of propofol by adding lidocaine before ERCP.
Methods:
Eighty ERCP patients with ASA I-III, aged between 45-75 years, were randomly divided into two groups. Lidocaine group (group L, n = 40), received 1-mg midazolam, 1.5 mg/kg lidocaine, and 1 mg/kg propofol intravenously. The control group (group C, n = 40) received 1-mg midazolam, saline in the same volume as the lidocaine group, and 1 mg/kg propofol intravenously. Propofol was administered with intermittent bolus doses. Propofol consumption, oropharyngeal reflex, recovery time, endoscopist satisfaction, ketamine need, and side-effects were recorded.
Results:
Propofol consumption during the procedure was statistically lower in group L than in the control group (157.25 ± 39.16 mg vs 228.75 ± 64.62 mg respectively, P < 0.001). Additionally, recovery time was statistically faster in group L compared with the control group (7.78 ± 3.95 min vs 11.92 ± 3.24 min respectively, P < 0.001). The oropharyngeal reflex was less in group L than control group (6/40 vs 15/40 respectively, P = 0.042). There was no significant difference between the two groups regarding visual analogue scale scores and endoscopist satisfaction (P > 0.05).
Conclusions:
We recommend the use of intravenous lidocaine before the ERCP procedure as it reduces propofol consumption, recovery times, and oropharyngeal reflex.
