A peri-parturient fifteen-month-old female Maine Coon cat was presented with extreme weakness and depression, profound hypovolaemia and hypothermia. Severe hyperkalaemia, hyponatraemia and anaemia were detected. Disseminated intravascular coagulation was suspected due to marked prolongation of activated partial thromboplastin time. Uterine torsion was diagnosed at exploratory laparotomy. The cat made a full recovery following ovariohysterectomy and intensive supportive therapy.

Alprazolam is a benzodiazepine anti-anxiety agent that acts at the limbic, thalamic, and hypothalamic level of the CNS and has anxioytic. sedative, hypnotic, skeletal muscle relaxant, and anticonvulsant properties. A retrospective study was conducted of 415 alprazolam ingestions in dogs reported to the ASPCA Animal Poison Control Center between January 1998 and August 2000: 238 suspected alprazolam toxicoses in dogs were evaluated. Clinical signs were ataxia/disorientation, depression, hyperactivity, vomiting, weakness, tremors, vocalization, tachycardia, tachypnea, hypothermia, diarrhea, and increased salivation that developed within 10-30 min post-ingestion. Treatment included standard decontamination procedures, such as emesis and activated charcoal: the specific benzodiazepine antagonist, flumazenil, may be used for severe CNS depression.

Brimonidine is an ophthalmic solution of 0.2% brimonidine tartrate used to lower intraocular pressure in human glaucoma patients. A retrospective study was conducted of brimonidine ophthalmic solution ingestion in 52 dogs reported to the ASPCA Animal Poison Control Center between January 1998 and December 2000. Eighty percent of the dogs were < 1-y of age. Approximate ingested dosages ranged from 0.18-5.55 mg/kg. Incidence of clinical signs were bradycardia (67%), depression (46%), ataxia (27%), hypotension (25%), pallor (23%), weakness (17%), change in mucous membrane color (17%), hypothermia (13%), vomiting or retching (13%.). Shock, weak pulses, and poor capillary refill time were also reported. Treatment involved early decontamination, supportive care, andyohimbine and atipamezole as specific alpha-2 antagonists that could be helpful in reversing the effects of brimonidine. Due to the possibility of severe cardiovascular effects developing, the ingestion of brimonidine ophthalmic solution in dogs should be considered dangerous.

The neuromuscular disorders described are divided into four groups: motoneuron diseases, peripheral neuropathies, disturbances of neuromuscular transmission and myopathies. In motoneuron diseases problems mainly result from respiratory insufficiency and the predisposition for aspiration caused by progressive muscular weakness. Depolarising muscle relaxants may elicit myotonic reaction and massive hyperkalemia. In contrast to non-depolarising muscle relaxants there may be an extreme hypersensitivity. In peripheral neuropathies the cardiac function is often limited whereby dysautonomia may enhance cardiovascular instability. The negative inotropic effect of anaesthetic agents must be observed with care and patients with higher degree of AV blocks may need a cardiac pacemaker during general anaesthesia. The Charcot-Marie-Tooth-Syndrome is characterized with a high sensitivity to thiopental. Disturbances of neuromuscular transmission frequently cause respiratory problems The fluctuating weakness of bulbar and respiratory muscles may impair swallowing and can lead to recurrent aspirations. Due to the reduced number of acetylcholine receptors the sensitivity to non-depolarizing muscle relaxants is elevated and the response to succinylcholine is reduced. Drugs reducing neuromuscular transmission such as antibiotics and beta-blockers may enhance these symptoms and should be avoided. In progressive muscular dystrophies the anaesthetic risk is mainly dependent on cardiac and respiratory impairment. Administration of succinylcholine leads to the risk of hyperkalmic cardiac arrest. Patients with metabolic myopathies are also at risk due to the involvement of cardiac muscle but respiratory problems are less frequent. Muscle metabolism should be supported by administration of substrates depending on the underlying disorder. In membrane disorders muscle rigidity (myotonic reactions) or weakness may lead to respiratory insufficiency. In addition to the depolarising muscle relaxants also anticholinesterase drugs, hypothermia and dyskalaemia can evoke myotonic reactions.

Sarin (O-isopropylmethylphosphonofluoridate) is a highly toxic nerve agent produced for chemical warfare. Sarin is an extremely potent acetylcholinesterase (AchE) inhibitor with high specificity and affinity for the enzyme. Death by sarin is due to anoxia resulting from airway obstruction, weakness of the muscles of respiration, convulsions and respiratory failure. The main clinical symptoms of acute toxicity of sarin are seizures, tremors and hypothermia. Exposure to sarin during incidents in Japan in 1994, 1995 and 1998, and possible exposure to low levels of sarin during the Gulf War, resulted in the deaths and injury of many people in Japan and caused possible long-term health effects on Gulf War veterans. Symptoms related to sarin poisoning in Japan still exist 1-3 years after the incident and include fatigue, asthenia, shoulder stiffness and blurred vision. Sarin produced seizures in rats and pigs. Recent studies showed that long-term exposure to low levels of sarin caused neurophysiological and behavioral alterations. Toxicity from sarin significantly increased following concurrent exposure to other chemicals such as pyridostigmine bromide. Further research to examine effects of sarin on the cellular and the molecular levels, gene transcription, endocrine system as well as its long-term impact is needed.

Pituitary coma is a rare case of emergency and primarily due to ACTH and TSH deficiency. Pituitary coma occurs more often in patients with well-known pituitary deficiency than in patients with intrasellar tumor. Clinical manifestations are hypotonia, bradycardia, decreased skin and nipple pigmentation, muscle weakness, vomitus, nausea, obstipation, hypothermia, and hypoventilation. A postpartal agalactia is often the first sign of Sheehan's syndrome. Unlike primary adrenal insufficiency (Addison's disease) ACTH deficiency does not cause hyperpigmentation, hyperkalemia, or salt loss. The suspicion of pituitary coma requires replacement with 100 mg hydrocortisone iv, 200 mg hydrocortisone iv/24 h, 500 micro g levothyroxine iv and fluid substitution. Since thyroxine accelerates the degradation of cortisol and can precipitate adrenal crisis in patients with limited pituitary reserve, hydrocortisone replacement should always precede levothyroxine therapy. ACTH stimulation test, CRH stimulation test and insulin tolerance test (optional) should be performed after therapeutic compensation to determine pituitary function.

Hypothermia, a reduction in the body's core temperature to <95.0 degrees F (<35.0 degrees C), is a preventable medical emergency usually caused by prolonged exposure to cold temperatures without adequate protective clothing. Warning signs and symptoms of hypothermia include lethargy, weakness and loss of coordination, confusion, uncontrollable shivering, and reduced respiratory or heart rate. Common risk factors are advanced age, substance abuse, altered mental status, and increased contact with substances that promote heat loss, such as water. This report describes three hypothermia-related deaths that occurred in the United States during 2003-2004, summarizes hypothermia-related mortality during 1979-2002, describes risk factors for and symptoms of hypothermia, and reviews measures to prevent hypothermia-related injury and death. Public health strategies tailored to persons at increased risk for exposure to excessive cold might help reduce hypothermia-related morbidity and mortality.

Cerebral palsy (CP) is a group of nonprogressive, motor impairment patterns due to an insult to the developing encephalon. Clinical manifestations vary by the specific motor deformity, anatomically affected region, and location of the brain injury. Spasticity is common, resulting in skeletal muscle weakness and loss of fine motor control. Spasticity in a child undergoing skeletal maturation may precipitate joint contractures and dislocation. Long-term medical care is interventional. The therapeutic goals are to increase the person's independence and improve the caretaker's ability to provide daily care. Early medical intervention to control spasticity and prevent contractures may reduce the need for future orthopedic surgical intervention. Centrally acting, tone-reducing medications may decrease spasticity but cause central nervous system side effects. Orthopedic surgical procedures may be necessary to remedy the chronic effects of increased tone on the muscles and bones of the extremities and spine. Anesthetic care of children and adolescents with CP is increasing. Thorough preoperative assessment facilitates preparation of an intraoperative care plan. Intellectual disability may attend CP and limit the person's ability to participate in preoperative preparation. Perioperative complications include hypothermia, intravascular depletion, muscle spasm, limb contracture, and seizure control. Gastroesophageal reflux and poor respiratory function might complicate anesthetic management.

A 6-day-old, female roan antelope (Hippotragus equinus cottoni) was diagnosed with a single intrahepatic portosystemic venous shunt at necropsy. Clinical signs had included weakness, lethargy, hypothermia, diarrhea, and a weak suckle response. Multiple seizure episodes were associated with hypoglycemia and characterized by vocalization, muscle fasciculations, and disorientation. Hematologic abnormalities included anemia with hypochromasia, anisocytosis, poikilocytosis, and leukopenia with neutropenia and lymphopenia. Serum biochemical abnormalities included elevations in blood urea nitrogen and total serum bile acid concentration. A portosystemic vascular anomaly should be a differential diagnosis for nonthriving, exotic ruminant calves with overt or subtle neurologic signs, persistent hypoglycemia, and/or elevated bile acids. In very young calves, total bile acid concentration may be more useful in establishing a diagnosis than blood ammonia concentration.
