This report describes a case of two-yr-old female with severe clinical Reye syndrome (Stage III and over), who was treated with not only conventional therapies but also mild hypothermia therapy. She presented acute episodes of tonic convulsion, hepatic dysfunction and intracranial hypertension. The first treatment consisted of the administration of anticonvulsant and mannitol, which were not effective to control intracranial pressure. Therefore, we induced mild hypothermia to rectal temperature of 33-34 degrees C for ten days to control intracranial hypertension as well as barbiturate therapy and hyperventilation under mechanical ventilation. Although she had hypokalemia, atelectasis of the right upper lung lobe and thrombocytopenia as the side effects during this therapy, we effectively controlled ICP. Glucose fluid therapy is recommended for Reye syndrome. We especially should pay attention to hypokalemia because of hyperventilation, absorption of potassium with insulin and transudation of potassium from the intestine. We determined the initiation and weaning of mild hypothermia therapy by findings of MRI as well as intracranial pressure. MRI findings will contribute to the determination of initiation and weaning of mild hypothermia therapy. Mild hypothermia therapy should be considered in patients with severe clinical Reye syndrome if conventional supportive therapies are not effective.

Urea Cycle Disorders (UCD) is an inborn error of urea synthesis in which ammonium and other nitrogenous precursors of urea accumulate leading to episodic coma and a high mortality rate. Therapy with peritoneal dialysis, essential amino acids or their nitrogen-free analogues has increased survival. The authors report 5 cases of urea cycle disorders, all of whom developed and were rescued from hyperammonemic coma. However, the eventual outcome was quite variable. Argininosuccinate lyase deficiency (ALD) Case 1. A 2 month old male infant, a product of a consanguineous marriage (Suphanburi province); developed poor feeding on day 7, lethargy, convulsion, hepatomegaly and respiratory alkalosis leading to respiratory failure and coma. Hyperammonemia, elevation of glutamic acid and argininosuccinic acid and its anhydrides confirmed the diagnosis of ALD. He is now 9 years old and severely retarded. Case 2. A male infant with history of lethargy, poor feeding on day 3, treated as sepsis and required respiratory support for 6 days; subsequently readmitted at age 2 weeks with vomitting, lethargy, seizure activity and hyperammonemia, and was treated by a local pediatrician in Songkhla province. There was a history of parental consanguinity and he was referred to Siriraj Hospital on day 64 with severe essential amino acid deficiency and acrodermatitis enteropathica with markedly elevated plasma citrulline level. In spite of aggressive treatment; the patient developed sepsis and he expired on day 78. Ornithine transcarbamylase deficiency (OTC) Case 3. An eleven-month-old male infant, the product of a non-consanguineous marriage, developed neonatal onset of hyperammonemia on day 5 after poor feeding, lethargy, hypothermia, seizure, apnea and coma. He was rescued from neonatal hyperammonemic coma on day 9 after aggressive treatment, but expired at eleven months of age after overwhelming sepsis. Case 4. A male infant, sibling of case 3 was referred to Siriraj Hospital on day 8 with hyperammonemia and coma. In spite of intensive genetic counseling given after the birth of their first child with OTC, the couple chose to have another baby without informing any physician. The baby developed vomiting and lethargy on day 2; subsequently hyperammonemia was noted. In spite of aggressive treatment given; hepatic dysfunction, renal failure and disseminated intravascular coagulation defects occurred on day 15. He expired on day 18 after parental permission for discontinuation of all treatment. Argininosuccinate synthetase deficiency (ASS) or Citrullinemia. Case 5. A seven week old female infant, the product of a consanguineous marriage and of Pakistani ethnic origin; developed intermittent vomiting from day 6. Initial diagnoses included ruminations, sepsis and pyloric stenosis for which she was operated on (day 30); however, vomiting continued; subsequently seizures, hyperammonemic coma developed and she was rescued from hyperammonemic coma within 30 hours. Significant elevations of citrulline and L-glutamine were demonstrated. She was discharged in excellent condition to her home in Dubai, the United Arab Emirates.

We report a case of severe rhabdomyolysis associated with Salmonella encephalopathy. A 3-year-old girl was admitted to our hospital because of status convulsives and unconsciousness. She was diagnosed as having Salmonella encephalopathy with rhabdmyolysis, and was treated by mild hypothermia and mechanical ventilation. Five days later she developed anuria with increased serum levels of myoglobin, CK and creatinine. And the diagnosis of acute renal failure was made. Peritoneal dialysis was begun from 6 days after admission. Hyperinfusion, the usual therapy of rhabdomyolysis, was not performed. She survived showing gradual improvement of renal function and consciousness. In a case of rhabdomyolysis complicating a neurologic disorder, a well-known poor prognostic factor, priority should be given to brain protection rather than to symptomatic treatment of rhabdomyolysis.

Cases of pediatric nonenvironmental hypothermia are uncommon. When presenting to the emergency department, these patients are often evaluated for possible sepsis/shock, brain tumors, endocrine disorders, and drug ingestions. We report a case of a 5-year-old girl who presented to the pediatric emergency department on two occasions with hypothermia and lethargy. She was found to have an unusual cause of her symptoms: episodic spontaneous hypothermia with hyperhidrosis.

We experienced a case of hypoxic brain damage induced by severe asthma who was successfully treated by hypothermia. A 20-year-old woman with a history of bronchial asthma suffered from severe respiratory distress and she stopped breathing for about 20 minutes. She was admitted to our hospital with respiratory arrest, deep coma, mydriasis and weak motor response to pain. She was intubated and mechanically ventilated with 100% oxygen. She was cooled down to 33 degrees C within 4 hours of her arrival. Her body temperature was maintained at about 33 degrees C for 2 days, and then gradually rewarmed. During hypothermia, PaCO2 was quite high(80-100 mmHg), but the intracranial pressure was kept low. After hypothermia therapy, she became free from consciousness disturbance and there were no neurological disorders except for mild myoclonus. Hypothermia has a possibility of effective therapy for patients with hypoxic brain damage after respiratory distress.

A 90-year-old woman was transferred to our hospital because of severe chest and back pain. Chest computed tomography (CT) scan showed impending rupture of the true aneurysm of the aortic arch. Emergent operation was performed under deep hypothermia and retrograde cerebral perfusion through median sternotomy. Ascending and transverse aorta were totally replaced with arch graft with 4 branches using the arch vessels first technique. Postoperative course was uneventful expect for urinary tract infection. She discharged from our hospital 76 days after the operation and is now doing well.

A 15-year-old female with short intestine syndrome due to chronic intestinal pseudo-obstruction associated with kidney failure underwent a multivisceral (stomach-duodenum-jejunum-ileum-pancreas-liver) and kidney transplant. She had required parenteral nutrition for the last 5 years, with numerous complications such as sepsis from the central catheter, deep venous thrombosis, severe liver dysfunction, pancytopenia due to bone marrow failure, and severe malnutrition. Surgery lasted 15 hours and was free of complications other than hypothermia, which worsened after revascularization of the grafts. Replacement of 6 units of blood products and crystalloids was required. Biochemical and hemodynamic variables were stable, apart from the development of hypernatremia, hyperglycemia, and lactic acidosis. The anesthetic approach included preoperative assessment of problems related to chronic parenteral nutrition (liver dysfunction, coagulopathy, and restricted venous access), the prevention of hypothermia, correction of electrolyte imbalance and the acid-base status, treatment of reperfusion syndrome, and the replacement of fluids and blood products to maintain circulatory homeostasis and assure sufficient splanchnic perfusion.

A 73-year-old woman with a history of hypertension and hyperlipidemia presented with a sharp pain ranging from the right shoulder to the upper limb. She had suffered a sharp pain at rest accompanied by general fatigue and nausea for about ten months prior to admission. Her white blood cell count was 12,800/microl, and her serum C-reactive protein was 17.5 mg/dl. A chest computed tomography scan revealed an aneurysmal change of the origin of the brachiocephalic artery. Pseudoaneurysm due to infection and aortic dissection was considered as a preoperative diagnosis. A total arch replacement was performed under cardiopulmonary bypass, deep hypothermia, and selective cerebral perfusion. Postoperatively, a bacteriologic culture of the contents of the aneurysm revealed Staphylococcus aureus. Perioperative administration of antibiotics was effective and the postoperative course was uneventful.

Malignant neoplasms rarely extend into the inferior vena cava and up to the right side of the heart. Although massive pulmonary tumor embolism occurs relatively rarely, it can be a catastrophic problem. Intraoperative pulmonary tumor embolism and cardiac arrest occurred in a 68-year-old woman while dissecting the inferior vena cava to resect a pararenal tumor extending into the retrohepatic inferior vena cava. Abrupt arterial hypotension, tachycardia, and increased central venous pressure lead to the diagnosis of massive pulmonary tumor embolism. Emergency cardiopulmonary bypass was commenced under profound hypothermia and cardiac arrest. The tumors in the main pulmonary artery were extracted, and fragments of remnant tumor were retrieved by a vascular endoscope, a Fogarty catheter, and milking of the lung. Following embolectomy, the tumor in the retrohepatic to infrarenal inferior vena cava was removed and the primary tumor together with the infrarenal inferior vena cava was resected under hepatic vascular exclusion and partial cardiopulmonary bypass. The inferior vena cava below the renal veins was not reconstructed. The patient recovered with slight retrograde amnesia. A postoperative pulmonary perfusion scintigram showed no defect in the pulmonary circulation. She is well now 8 months after surgery. Safe prevention measures should be accomplished as a part of the perioperative management of patients with inferior vena cava tumor thrombus that may be fragile, and cardiopulmonary bypass should always be stand-by on surgery.
