Most traditional opioids and non-steroidal anti-inflammatory drugs that are used to control perioperative pain have substantial side effects. The number of choices in clinical use was recently increased by two promising groups of drugs: N-methyl-D-aspartate receptor antagonists and central alpha2 agonists. One N-methyl-D-aspartate antagonist, dextromethorphan, blocks the generation of central pain sensation that arise from peripheral nociceptive stimuli by moderating the activity of N-methyl-D-aspartate. ⋯ Dexmedetomidine is a relatively new, highly selective central alpha2 agonist. Its sedative, pro-anaesthetic and pro-analgesic effects at 0.5-2 microg/kg given intravenously stem mainly from its ability to blunt the central sympathetic response by as yet unknown mechanism(s) of action. It also minimises opioid-induced muscle rigidity, lessens postoperative shivering, causes minimal respiratory depression, and has haemodynamic stabilising effects.

To assess our management of gunshot injuries of the extrahepatic biliary ducts. ⋯ Roux-en-Y biliary-jejunal anastomosis is appropriate in the treatment of gunshot injuries of the extrahepatic biliary ducts as there is always a degree of tissue loss and some debridement is required, making it difficult to do a tension-free anastomosis.
