1/35. succinylcholine induced hyperkalemia and cardiac arrest death related to an EEG study.Changes in EEGs during cardiac arrest have been described in detail by many authors; however, mortality because of an EEG has never been reported. The authors report the case of a patient who developed cardiac arrest causally related to administration of succinylcholine for reduction of excessive amounts of myogenic artifact during an EEG. This case indicates the need for caution when doing an EEG study in an intensive care unit setting.- - - - - - - - - - ranking = 1keywords = hyperkalemia (Clic here for more details about this article) |
2/35. Asystole during combination chemotherapy for non-Hodgkin's lymphoma: the acute tumor lysis syndrome.The acute tumor lysis syndrome is a rare condition that has most frequently been documented in patients with rapidly dividing myeloproliferative and lymphoproliferative malignancies. It is characterized by the development of hyperuricemia, hyperkalemia, hyperphosphatemia, hypocalcemia, acute renal failure and metabolic acidosis, as a result of massive tumor cell destruction, usually secondary to effective cytotoxic treatment. We want to present the case history of a 62-year-old woman who died from cardiorespiratory arrest during combination chemotherapy for non-Hodgkin's lymphoma due to acute tumor lysis syndrome. Despite general preventive measures, severe electrolyte abnormalities developed within 18 h of the start of chemotherapy. The general guidelines for the management of this potentially fatal oncologic emergency are discussed, with special emphasis on the pathogenetic mechanisms and risk factors in our patient.- - - - - - - - - - ranking = 0.25keywords = hyperkalemia (Clic here for more details about this article) |
3/35. Cardiac arrest due to succinylcholine-induced hyperkalemia in a patient with wound botulism.Cardiac arrest due to hyperkalemia is a known complication of succinylcholine administration in patients with neuromuscular disease, extensive burns, and prolonged immobility. We report a case of hyperkalemic cardiac arrest following the administration of succinylcholine in a patient suffering from wound botulism.- - - - - - - - - - ranking = 1.25keywords = hyperkalemia (Clic here for more details about this article) |
4/35. Acute tumor lysis syndrome with choriocarcinoma.A 52-year-old man with retroperitoneal nodal, lung, and liver metastases from choriocarcinoma received chemotherapy with etoposide, cisplatin, and bleomycin. Within 48 hours of starting treatment, he had hypotension, hypoxemia, and anuria. Laboratory values showed hyperuricemia, hyperkalemia, hyperphosphatemia, hypocalcemia, and metabolic acidosis. He was placed on mechanical ventilation, and hemodialysis was instituted, with marked improvement in renal function. A second, shortened course of chemotherapy with carboplatin and etoposide was given 21 days later. However, on hospital day 48, the patient died of progressive pulmonary insufficiency and cardiac arrest. This represents the first reported case of acute tumor lysis syndrome after systemic chemotherapy for advanced nonseminomatous germ cell cancer.- - - - - - - - - - ranking = 0.25keywords = hyperkalemia (Clic here for more details about this article) |
5/35. Hyperkalemic cardiac arrest successfully reversed by hemodialysis during cardiopulmonary resuscitation: case report.Severe hyperkalemia is a potential life-threatening cardiac emergency especially in the patients who suffer from a defective renal capacity to excrete potassium such as the dialysis patient. Various conventional therapies including intravenous sodium bicarbonate, insulin with glucose and several beta-2 agonists are commonly employed as transient measures to enhance shift of potassium from the extracellular to the intracellular compartment. If the potassium load is massive and situation is critical, emergency hemodialysis may be useful. During cardiopulmonary resuscitation, the external cardiac compression can support adequate blood flow for hemodialysis. We report a case of a 68-year-old woman who developed sudden cardiac arrest secondary to hyperkalemia with renal insufficiency. Despite 100 minutes of cardiopulmonary resuscitation and conventional treatment for hyperkalemia, the cardiac arrest still persisted. Hemodialysis was then initiated during cardiopulmonary resuscitation and the patient restored spontaneous heart beat 20 minutes later. There was no neurologic sequela after her recovery. Hemodialysis should be considered early in the course of cardiopulmonary resuscitation in severe hyperkalemia induced cardiac arrest if conventional therapies were judged to be ineffective.- - - - - - - - - - ranking = 1keywords = hyperkalemia (Clic here for more details about this article) |
6/35. lidocaine-induced conduction disturbance in patients with systemic hyperkalemia.We report 2 cases in which lidocaine, given for wide-complex tachycardia in the presence of hyperkalemia, precipitated profound conduction disturbance and asystole. The electrophysiologic effects of hyperkalemia and its interaction with lidocaine are reviewed. In patients with known hyperkalemia and wide-complex tachycardia, treatment should be directed at hyperkalemia, rather than following treatment algorithms for wide-complex tachycardia.- - - - - - - - - - ranking = 2keywords = hyperkalemia (Clic here for more details about this article) |
7/35. Geophagia. A cause of life-threatening hyperkalemia in patients with chronic renal failure.Geophagia has been associated with life-threatening hyperkalemia in five patients with chronic renal failure. All five patients were black and had been born in the southeastern united states. Four had had frequent hyperkalemia requiring at least one hospitalization, and two had had hyperkalemia with serum potassium concentration as high as 9.8 mEq/liter, resulting in cardiac arrest in one and paralysis, disorientation, and cardiac arrythmia in the other. Since riverbed clay contains as much as 100 mEq of potassium in 100 gm of clay, much of which is exchangeable at acid pH, the mechanism of geophagia-induced hyperkalemia appears to be the absorption of potassium released from clay after ingestion. After discontinuing geophagia, no new hyperkalemic episodes occurred in these patients.- - - - - - - - - - ranking = 2keywords = hyperkalemia (Clic here for more details about this article) |
8/35. Cardiac arrest in an infant with congenital adrenal hyperplasia.We report a 3-month-old boy who suffered an out-of-hospital cardiac arrest. During resuscitation, the medical team was informed that he was receiving hydrocortisone treatment. The possibility of adrenal insufficiency with hyperkalemic cardiac arrest prompted the administration of calcium, which resulted in the return of spontaneous circulation. The infant's diagnosis of congenital adrenal hyperplasia was not spontaneously mentioned by the parents. This case illustrates the importance of obtaining adequate parental information and considering hyperkalemia as a possible cause of cardiac arrest.- - - - - - - - - - ranking = 0.25keywords = hyperkalemia (Clic here for more details about this article) |
9/35. gas gangrene pyaemia with myocardial abscess formation--fatal outcome from a rare infection nowadays.We report a case of sudden death after gas gangrene. A 67-year-old male patient with diabetes mellitus and chronic renal failure (on haemodialysis three times a week) presented in the surgical emergency department with a severe swelling and crepitation in the right groin. No signs of trauma were present-except for a well-healed, 1-year-old scar after femoro-popliteal bypass surgery. Two days earlier, he had presented to the internal medicine department with epigastric pain and had left against medical advice. On readmission the patient was initially conscious and in a stable cardiopulmonary condition but developed sudden cardiocirculatory failure and underwent resuscitation. Despite all resuscitation measures, including the administration of high doses of catecholamines and the treatment of hyperkalemia, the patient died. autopsy revealed septicaemia with rod-shaped gram-positive bacteria, typical of clostridium perfringens, evidenced by multiple areas of myonecrosis. abscess formation was found in the myocardium. Clostridial gas gangrene is a rare clinical condition. Unless immediate diagnosis and adequate therapy measures are taken, the outcome and chances for survival are poor as demonstrated by this case.- - - - - - - - - - ranking = 0.25keywords = hyperkalemia (Clic here for more details about this article) |
10/35. hyperkalemia in fatal MDMA ('ecstasy') toxicity.3,4-Methylenedioxymethamphetamine (MDMA, 'ecstasy') is an amphetamine synthetic analog widely used as an recreational drug. Acute and severe toxic effects following MDMA ingestion include hyperthermia, arrhythmias, rhabdomyolisis, disseminated intravascular coagulation, hepatotoxicity and even death. Recently, we treated a patient in whom hyperkalemia, in the absence of renal failure, aggravated the expected toxic complications of MDMA, becoming the immediate cause of his death.- - - - - - - - - - ranking = 0.25keywords = hyperkalemia (Clic here for more details about this article) |
