1/2. Combination propofol-ketamine anaesthesia in sick neonates.Two critically ill, opioid-tolerant neonates were anaesthetized using pancuronium and a mixture of propofol (PROP) and ketamine (KET). Three mg of KET were added per ml (10 mg) of PROP in a single syringe and infused at a rate of 100-150 microg x kg(-1) x min(-1) of the PROP component (30-45 microg x kg(-1) x min(-1) KET). Total doses of 12-15 and 3.6-4.5 mg x kg(-1) of PROP and KET, respectively, were administered. Both patients remained haemodynamically stable throughout their surgical procedures. PROP-KET is a rational and effective combination for intravenous anaesthesia in critically ill neonates who are likely to be opioid-tolerant when an anaesthesia vaporizer is not readily available.- - - - - - - - - - ranking = 1keywords = anaesthesia (Clic here for more details about this article) |
2/2. Intentional overdose of Large Animal Immobilon.We describe a case of voluntary self-injection with Large Animal Immobilon, a veterinary anaesthesia product containing etorphine, a very strong opioid, and acepromazine, a phenothiazine. This resulted in cardiorespiratory arrest and the need for sustained haemodynamic support after resuscitation. Large Animal Immobilon is used under specific conditions only, mainly in zoo and wildlife medicine. Primary toxicological analysis, although guided by the presumed toxin, could only detect a metabolite of acepromazine in the urine. Further analysis was able to show some traces of etorphine. A number of topics are treated, including the apparent potency of the etorphine and the selection of a suitable antidote, taking into account the different properties of the respective agents.- - - - - - - - - - ranking = 0.16666666666667keywords = anaesthesia (Clic here for more details about this article) |
