By Irowa OO and Agbonrofo PI.
Abstract
Context
Colonoscopy is a valuable armamentarium for the diagnosis of lesions in the colon. Sedation/anaesthesia makes the procedure easier and tolerable in patients with good bowel preparation. Poor tolerability is one of the reasons for incomplete colonoscopy.
Objectives
To share our experience with the use of Pentazocine, Promethazine, and Midazolam during colonoscopy, highlighting, the indication for colonoscopy, the tolerability of the procedure, success rate (Caecal intubation rate), and lesional findings. Materials and Methods: This is a 2-year descriptive cross-sectional study of patients referred for colonoscopy in the University of Benin Teaching Hospital. All patients received intravenous single-dose Pentazocine, Promethazine, and Midazolam. They were monitored during the procedure. Patients who required additional doses of Midazolam were adjudged to have poorly tolerated the procedure. The patient's demographics, indication for colonoscopy, colonoscopy findings, histology of specimens, and the tolerability of the procedure were entered into a proforma and analyzed.
