Overview
The insertion of a urinary catheter in a patient undergoing a surgical procedure, especially urinary interventions, may lead to catheter-related bladder discomfort (CRBD) with varying degrees of severity during the postoperative period. Paracetamol is a drug with proven efficacy for the management of mild and moderate postoperative pain. Tramadol is a centrally acting, synthetic opioid analgesic with weak opioid agonist properties. It inhibits the detrusor activity by inhibition of type-1 muscarinic (M1) and type-3 muscarinic (M3) receptors. Dexmedetomidine, a highly selective α2-adrenergic receptor agonist, with analgesic, sedative, anxiolysis, sympatholytic, and sedative properties, is a very useful associated agent for general anesthesia.
