1/4. Anaesthesia for Friedreich's ataxia. Case report.Friedreich's ataxia is an inherited neuromuscular disorder often associated with significant cardiac disease and requiring special care during anaesthesia because of increased sensitivity to muscle relaxants. We report a 37 years old female patient with Friedreich's ataxia who underwent anaesthesia for total hip replacement because of degenerative hip arthritis. Anaesthesia was induced with alfentanil and propofol. Endotracheal intubation was achieved without the use of any muscle relaxants and muscle relaxants were avoided throughout the operation. Anaesthesia was maintained with propofol infusion and intermittent bolus doses of alfentanil. At the end of the procedure recovery from anaesthesia was fast and uneventful. When there is no absolute indication for neuromuscular blocking agents as its the case for many orthopaedic operations, avoiding these drugs would simply avoid many potential complications due to muscle relaxant use in this group of patients.- - - - - - - - - - ranking = 1keywords = anaesthesia (Clic here for more details about this article) |
2/4. Rocuronium for muscle relaxation in two children with Friedreich's ataxia.Friedreich's ataxia is a rare hereditary neurodegenerative disease caused by a defect in the gene that encodes a mitochondrial protein called frataxin. We report the use of rocuronium 0.6 mg kg(-1) in two adolescent girls with Friedreich's ataxia undergoing propofol-sufentanil-oxygen-air anaesthesia for spinal surgery. Neuromuscular transmission was monitored using acceleromyography, and onset and recovery times were recorded. The clinical duration of rocuronium was comparable to that of children without neuromuscular disease (25% recovery T(1)=44 and 24 min for patients 1 and 2 respectively).- - - - - - - - - - ranking = 0.33333333333333keywords = anaesthesia (Clic here for more details about this article) |
3/4. Anaesthesia for a patient with Friedreich's ataxia and cardiomyopathy.Friedreich's ataxia is an inherited neuromuscular disorder often associated with significant cardiac disease. We report a case of Friedreich's ataxia in a 13-year-old girl with ulcerative colitis and hypertrophic cardiomyopathy who was successfully managed for subtotal colectomy with general anaesthesia and epidural narcotic. Anaesthetic considerations included the maintenance of fluid volume and stable cardiovascular variables in the intra- and postoperative periods.- - - - - - - - - - ranking = 0.33333333333333keywords = anaesthesia (Clic here for more details about this article) |
4/4. Requirements for muscle relaxation in Friedreich's ataxia.Friedreich's ataxia is an inherited disorder of the nervous system, requiring special care during anaesthesia, because of increased sensitivity to muscle relaxants. We report a case of Friedreich's ataxia in a 31-year-old woman, anaesthetised on two occasions, for tendinoplasty and pes cavus repair. atracurium was used for neuromuscular blockade and monitored by a train-of-four twitch technique. The patient's response was normal. She returned to adequate spontaneous breathing within 20 min of the last dose of the muscle relaxant without need for anticholinesterase administration. When neuromuscular function is monitored, normal doses of muscle relaxant can safely be used in these patients.- - - - - - - - - - ranking = 0.33333333333333keywords = anaesthesia (Clic here for more details about this article) |
