Postnatal day-14 (P14) infant rats remained naive or were implanted with osmotic minipumps infusing saline or fentanyl (50 microg kg(-1) h(-1)). Fentanyl was administered 72 h later for measurement of antinociception in the tail-flick test. The potency of fentanyl was 3.0-fold lower in fentanyl-infused compared to saline-infused P17 rats. Fentanyl-infused P17 rats injected with naloxone underwent withdrawal characterized by increases in spontaneous activity, wall climbing, diarrhea, abdominal stretching, forepaw treading/tremors, wet-dog shakes, jumping, ptosis, rhinorrhea and hypothermia. Other naive, saline-infused and fentanyl-infused P17 rats not challenged with fentanyl or naloxone were housed until maturing into P42 juveniles. Fentanyl's potency was equal among each treatment group. However, morphine's potency was reduced in juveniles tolerant to fentanyl as infants. Morphine was also less potent in P90 adults tolerant to fentanyl as infants. Thus, chronic opiate exposure during infancy may affect the developing central nervous system, and desensitize animals and humans to opiate analgesia throughout life.

Patients diagnosed with ocular myasthenia gravis (MG) and mitral valve disease represent a significant perioperative management problem, especially for the anaesthesiologist, due to complex inter-actions between the disease, drugs to treat the disease, and anaesthetic agents, such as neuromuscu-lar blocking agents (NMBAs). This paper describes the successful management of a 31-year-old female with mitral valve stenosis and ocular MG who was diagnosed with MG 4 years prior to the indication for cardiac surgery. Preoperatively, the patient was under treatment with Pyridostigmine and Prednisone. Mitral valve replacement and full thymectomy were performed, under general anaesthesia, using Fentanyl, Sevoflurane and low doses of non-depolarising NMBAs. The postoperative course was uneventful, the patient was extubated at 6 hours postoperatively, in-tensive care unit stay was 48 hours, and the patient was discharged after 6 days without any compli-cations. After 3 months, at the follow-up examination, the patient's ocular symptoms (eyelid ptosis) disappeared.
