Abstract
Non-steroidal anti-inflammatory drugs (NSAID) are now commonly used in the treatment of postoperative pain. In normovolaemic conditions, prostaglandins do not seem to play a substantial role in maintaining renal function. However, numerous studies have shown that during activation of vasoconstrictor systems the synthesis of renal prostaglandins counteracts the vasoconstrictor effects and thereby maintains renal function. In animals, renal blood flow and GFR are markedly decreased when an NSAID is administered in the presence of renal hypoperfusion. Major surgery decreases renal function secondary to stimulation of the adrenosympathetic system and the renin-angiotensin system, and it has previously been demonstrated that maintenance of renal blood flow during laparotomy in dogs depends on an intact prostaglandin synthesis. Perioperative effects of NSAIDs are only sparsely investigated in humans, and studies on the effect on renal haemodynamics have not been presented. As in unanaesthetized volunteers, NSAID have been found to decrease the postoperative excretion of water, sodium and potassium. It therefore still remains unclarified whether general anaesthesia and surgery increase the risk of renal side effects of NSAIDs. Because of the potential risk of peri- and postoperative complications that may further deteriorate renal function, NSAIDs should not be used preoperatively, and not in patients in unstable haemodynamic states.
