| 相互作用 | BACKGROUND AND OBJECTIVE: We have evaluated the effects of propofol and its relationship with K+ channels on human isolated umbilical vessels. METHODS: Umbilical vessel rings were suspended in isolated organ baths containing Krebs-Ringer solution. In the first series of experiments the effect of propofol (10(-9)-10(-4) M) was examined in a concentration-dependent manner on umbilical vessels precontracted with KCl (60 mmol). In the second series, these effects were studied in the presence of tetraethylammonium. RESULTS: A mild contraction was produced by low dose propofol in both precontracted umbilical artery and umbilical vein segments. 10(-4) M propofol caused significant relaxation in both umbilical artery and umbilical vein. The relaxation response was significantly reduced by the addition of 10(-1) M tetraethylammonium. CONCLUSION: These results suggested that the responses of propofol on KCl-induced contractions of both umbilical artery and vein were dose dependent, and this effect involved Ca2+ activated K+ channels.The nature of KCl-induced relaxations of the rat anococcygeus muscle was investigated. 2. The relaxations were mimicked by other K+ salts, but not by NaCl. 3. The muscle was more susceptible to the relaxant effects of KCl than the contractile effects. 4. Addition of ouabain (100 micron) had no effect on the relaxations. 5. The relaxations were abolished by tetrodotoxin (5 microgram/mL), procaine (500 micron), and by section of the inhibitory nerves. 6. The results suggest that KCl-induced relaxations are due to stimulation of the inhibitory nerves by K+.Twelve male mongrel dogs were used for this studysix were untreated (control) and six were given intravenous furosemide (1 mg/kg) daily for seven consecutive days before each study. Each animal received intravenous KCl 0.8, 1.6 or 3.2 mMol/kg/hr for one hour, but only one dose for each study and at least seven days were allowed between studies. The animals were given thiopentone for tracheal intubation and mechanically ventilated, maintaining a PaCO2 of 4.0 to 4.5 kPa (30-35 torr) and anaesthetized with nitrous oxide-oxygen and halothane. Daily administration of furosemide reduced serum potassium from 4.48 to 4.09 mMol/1 with no significant change in serum sodium. A greater number of furosemide-pretreated animals (6 vs 3) developed cardiac dysrhythmias during non-lethal intravenous KCl at 0.8, 1.6 mMol/kg/hr. The furosemide-pretreated group tended to succumb at a lower serum potassium concentration (12.2 vs 13.8 mMol/I, P less than 0.05) and developed earlier onset (44 vs 54 min, P less than 0.05) of cardiac standstill or ventricular fibrillation following intravenous KCl at 3.2 mMol/kg/hr. Cardiac output, heart rate and mean arterial pressure were significantly elevated during serum concentrations of 6.9-9.1 mMol/1, while no statistically significant changes were observed for stroke volume and peripheral resistance. There were no significant differences of urinary potassium excretion between the untreated and treated groups when like doses of KCl were infused. These data suggest that acute infusion of KCl in furosemide-pretreated dogs may not be an effective means of treating hypokalaemia and could be hazardous.The effect of s.c. administration of deoxycorticosterone acetate (DOCA) plus p.o. treatment with NaCl solution on gastric carcinogenesis induced by N-methyl-N'-nitro-N-nitrosoguanidine and the effect of p.o. potassium supplementation on the enhanced induction of gastric carcinogenesis in DOCA-NaCl rats were investigated in Wistar rats. After 25 weeks of p.o. treatment with the carcinogen, rats received s.c. injections of DOCA (50 mg/kg) twice a week and were given 1% NaCl solution with and without 1% KCl as drinking water. In Week 52, the blood pressure, the incidence of gastric cancer, and the number of cancers per rat were significantly greater in DOCA-NaCl rats than in the untreated group. Prolonged p.o. treatment of DOCA-NaCl hypertensive rats with potassium significantly reduced their blood pressure, the incidence of gastric cancers, and their number per rat. All gastric tumors were in the glandular portions of the stomach. The norepinephrine concentration in the gastric wall and the labeling indices of gastric mucosa were significantly greater in DOCA-NaCl hypertensive rats than in the untreated group, but p.o. potassium supplementation significantly reduced the norepinephrine concentration in the gastric wall and the labeling indices of the gastric mucosa in DOCA-NaCl rats. Thus, administration of DOCA and NaCl increased the norepinephrine concentration in the gastric wall and promoted gastric carcinogenesis, and p.o. potassium supplementation decreased the norepinephrine concentration in the gastric rats. Inasmuch as the norepinephrine concentration has been used as a marker of sympathetic nervous activity, these findings suggest that the sympathetic nervous system plays an important role in gastric carcinogenesis, probably associated with cell proliferation of antral epithelial cells.For more Interactions (Complete) data for POTASSIUM CHLORIDE (20 total), please visit the HSDB record page. |

| 健康影响 | The administration of oral potassium salts to persons with normal excretory mechanisms for potassium rarely causes serious hyperkalemia. However, if excretory mechanisms are impaired, of if potassium is administered too rapidly intravenously, potentially fatal hyperkalemia can result. It is important to recognize that hyperkalemia is usually asymptomatic and may be manifested only by an increased serum potassium concentration (6.5-8.0 mEq/L) and characteristic electrocardiographic changes (peaking of T-waves, loss of P-wave, depression of S-T segment, and prolongation of the QT interval). Late manifestations include muscle paralysis and cardiovascular collapse from cardiac arrest (9-12 mEq/L). |

| 不良影响 | Adverse effects from normal use of KCl are typically related to the administration route. The FDA notes particular adverse effects for each administration route. In general, oral formulations most commonly correlate with GI irritation, including vomiting and diarrhea. Tablet and capsule forms may cause ulcerative/stenotic lesions with prolonged exposure to GI surfaces. Injectable KCl formulations have the potential to cause injection site complications (e.g., phlebitis, erythema, thrombosis, etc.). Also, rapid injection of KCl can precipitate mild hyperkalemia. This review discusses the symptoms of hyperkalemia in the Toxicity section. |

| 毒性概述 | IDENTIFICATION AND USE: Potassium chloride (KCl) consists of odorless white crystals or crystalline powder or white granular powder or colorless crystals, with a strong saline taste. It is not registered for current pesticide use in the U.S., but approved pesticide uses may change periodically and so federal, state and local authorities must be consulted for currently approved uses. KCl is used as prevention and treatment of potassium deficiency, e.g. when thiazide diuretics or corticosteroids are used in case of excessive vomiting or diarrhea, or diets poor in potassiumin the treatment of cumulative digitalis poisoningand as a component of lethal injections. It is also used in the fertilizer industry as potash and in buffer solutions for photography. Potassium chloride has been identified as being used in hydraulic fracturing as a clay stabilizer. HUMAN EXPOSURE AND TOXICITY: KCl is an essential constituent of the body for intracellular osmotic pressure and buffering, cell permeability, acid-base balance, muscle contraction and nerve function. In humans, acute oral toxicity is rare because large single doses induce nausea and vomiting, and because KCl is rapidly excreted in the absence of any pre-existing kidney damage. Symptoms of acute poisoning after ingestion of potassium chloride are usually mild. KCl oral overdoses manifests in neuromuscular signs in the form of hyperkalemia, general muscular weakness and ascending paralysis, listlessness, vertigo, mental confusion, hypotension, acute cardiovascular changes with ECG abnormalities, and heart block. Gastrointestinal symptoms manifest as nausea, vomiting, paralytic ileus, and local mucosal necrosis, which may lead to perforation. There are several case reports of accidental iv or ip administrations of KCl. Symptoms of acute poisoning after parenteral administration are similar to symptoms after oral exposure but can appear more promptly and be more severe. A case report of a subcutaneous injection of KCl reports chemical burns and skin lesions. During routine spinal anesthesia, an injection of 15 mL of 15% KCl (30 mM) mixed with bupivacaine epidurally caused permanent parapalegia and an ampule of potassium chloride, instead of bupivacaine, was mistakenly opened and inadvertently administered intrathecally to a patient, resulting in pain, cramps, and death within 2.5 hours of injection. Usual therapeutic doses of potassium for oral solution-adults are 1.5-3 g/day to prevent depletion, and 3-7.5 g/day for replacement. A threshold concentration for skin irritancy of 60 % was seen when KCl in aqueous solution was in contact with skin of human volunteers. The threshold concentration when applied to broken skin was 5 %. Gastro-intestinal irritant effects in humans caused by KCl administrated orally have been reported at doses from about 31 mg/kg bw/day. One epidemiological investigation among potash miners disclosed no evidence of predisposition of underground miners to any of the diseases evaluated, including lung cancer. ANIMAL STUDIES: No evidence of treatment-related carcinogenicity was observed in rats administered up to 1820 mg KCl/kg body weight/day through the food in a 2 year study. A developmental study revealed no fetotoxic or teratogenic effects of KCl in doses up to 235 mg/kg/day (mice) and 310 mg/kg/day (rats). No gene mutations were reported in bacterial tests, with and without metabolic activation. However, high concentrations of KCl showed positive results in a range of genotoxic screening assays using mammalian cells in culture. The action of KCl in culture seems to be an indirect effect associated with an increased osmotic pressure and concentration. ECOTOXICITY STUDIES: In short-term acute toxicity tests with fish, daphnia and algae the following results were found (lowest test result values): Ictalurus punctulus 48hr-LC50 = 720 mg/LDaphnia magna: 48h-LC50 = 177 mg/LNitzschia linearis: 120 h-EC50 = 1337 mg/L. A chronic reproductive test with the invertebrate Daphnia magna gave a LOEC of 101 mg/L. All the studies compiled on the acute and chronic aquatic toxicity were > 100 mg/L. Thus it is concluded that KCl is not hazardous to freshwater organisms.KCl toxicity is primarily a discussion of hyperkalemia. Like hypokalemia, the potentially fatal complication of hyperkalemia is cardiac arrhythmia. The risk for cardiac arrhythmia is significant at serum potassium levels greater than 6.0 to 6.5 mEq/L. Other manifestations of symptomatic hyperkalemia include ascending muscle weakness and GI disturbance (e.g., nausea, local mucosal necrosis, etc.).Supplemental potassium in the form of high potassium food or potassium chloride may be able to restore normal potassium levels. |

| 生态毒性摘录 | /AQUATIC SPECIES/ Indigenous species are less commonly used in laboratory aquatic toxicity tests compared with standard test species due to (1) limited availability lack of requisite information necessary for their acclimation and maintenance under laboratory conditions and (2) lack of information on their sensitivity and the reproducibility of toxicity test results. As part of the Natural Resource Damage Assessment aquatic toxicity program in response to the Deepwater Horizon Oil incident (2010), sensitive life stages of native Gulf of Mexico species were evaluated in laboratory toxicity tests to determine the potential effects of the spill. Fish (n = 5) and invertebrates (n = 2) selected for this program include the following: the Florida pompano (Trachinotus carolinus), red drum (Sciaenops ocellatus), spotted sea trout (Cynoscion nebulosus), cobia (Rachycentron canadum), red porgy (Pagrus pagrus), blue crab (Callinectes sapidus), and the common moon jellyfish (Aurelia aurita). Initially in the program, to establish part of the background information, acute tests with reference toxicants (CdCl2, KCl, CuSO4) were performed with each species to establish data on intraspecies variability and test precision as well as identify other factors that may affect toxicity results. Median lethal concentration (LC50) values were calculated for each acute toxicity test with average LC50 values ranging from 248 to 862 mg/L for fish exposures to potassium chloride. Variability between test results was determined for each species by calculating the coefficient of variation (%CV) based on LC50 values. CVs ranged from 11.2 % for pompano (96-hr LC50 value) to 74.8 % for red porgy 24-hr tests. Cadmium chloride acute toxicity tests with the jellyfish A. aurita had the lowest overall CV of 3.6 %. By understanding acute toxicity to these native organisms from a compound with known toxicity ranges and the variability in test results, acute tests with nonstandard species can be better interpreted and used appropriately when determining risk./AQUATIC SPECIES/ Various nutrients, including K+ and NO3-, are increasingly being discharged into aquatic systems via anthropogenic sources, which may impact marine organisms. The present study was conducted on blue swimmer crab (Portunus pelagicus) early juveniles to determine the acute toxicity of NaNO3, KNO3, and KClif a toxicity interaction exists between K+ and NO3-the hemolymph Na+, K+, and Ca2+ changesand the gill histopathological alterations following exposure to elevated NaNO3, KNO3, and KCl levels. A total of 20 replicate crabs were exposed to each of the five NaNO3, KNO3, and KCl concentrations for 96 h. After 96 hr, the surviving crabs were sampled for hemolymph Na+, K+, and Ca2+ levels and fixed for histological examination of the anterior gills. The 96-hr median lethal concentration of NaNO3-N, KNO3-N, KNO3-K, and KCl-K was 3,452, 112, 312, and 356 mg/L, respectively, for early P. pelagicus juveniles. The toxicity of NaNO3-N was significantly less (p < 0.01) than that of KNO3-N. Furthermore, at the same K+ levels, KNO3-K was significantly (p < 0.05) more toxic than KCl-K, indicating a toxicity interaction between K+ and NO3-. Following exposure to elevated KNO3 and KCl levels, the crabs had significantly higher (p < 0.01) hemolymph K+ levels compared to the control. Conversely, following exposure to elevated NaNO3 concentrations, the crabs had significantly higher (p < 0.01) hemolymph Na+ levels but significantly lower (p < 0.01) hemolymph K+ levels. Despite the markedly different hemolymph ionic changes following NaNO3 and KNO3/KCl exposure, the histopathological changes to the anterior gill lamellae of the crabs appeared to be similar, including lamellae swelling, epithelial thickening, pillar cell disruption, necrosis, and distortion. |

| Human Toxicity Excerpts | /HUMAN EXPOSURE STUDIES/ Lethal injection of potassium chloride (KCl) can be used as a method of either suicide or homicide. As biological tests are still inadequate to differentiate endogenous from exogenous potassium, at the scene of death the cause can only be suspected. We wished to determine the usefulness of conventional pathological examination in this context and carried out a study in four fetuses after medical termination of pregnancy for serious disease. Pregnancy was terminated by KCl injection in two cases and by injection of lidocaine and sufentanil in the other two cases. In each of the two fetuses in which KCl injection was performed, macroscopic examination showed whitish deposits on the tissues and histological examination showed clumps of lanceolate crystals in the internal organs. In the two fetuses which received lidocaine and sufentanil injection, no deposits were visible on macroscopic examination and no crystals were seen on histological examination. These findings suggest that pathological study may have useful applications in forensic medicine when death by potassium injection is suspected./HUMAN EXPOSURE STUDIES/ Potassium chloride was compared with triamterene in a crossover trial involving 16 hypertensive patients with overt diuretic-induced hypokalemia. Potassium chloride, 24 to 96 mEq/day, normalized the plasma potassium (PK) level at 3.5 mEq/L or more in only eight of the patients. The average increase in PK level was 0.58 mEq/L. Triamterene, 50 to 200 mg daily, normalized PK level in ten of the patients. The average increase in PK level was 0.72 mEq/L, which was not significantly different than that with potassium therapy. Some patients who responded to potassium did not respond to triamterene, and vice versa. Most of the administered potassium was excreted in the urine even with persisting hypokalemia. Addition of triamterene to diuretic therapy resulted in a small but statistically significant increase in plasma creatinine level./HUMAN EXPOSURE STUDIES/ The effects of two dosage forms of wax-polymer matrix potassium chloride on the upper gastrointestinal mucosa were compared with placebo in 44 healthy volunteers. After 2 weeks of potassium chloride treatment, mucosal toxicity was observed. There was no correlation between the presence of lesions and symptoms. Six of seven volunteers with lesions healed spontaneously despite continuing treatment with potassium chloride./HUMAN EXPOSURE STUDIES/ OBJECTIVES: Induction of fetal demise before second-trimester termination is performed for a number of reasons. One method for inducing fetal demise is via sonographically guided intracardiac KCl (KCl) injection. We performed a retrospective cohort study to determine the efficacy and safety of intracardiac KCl injection as a method of second-trimester induced fetal demise. METHODS: We reviewed records from patients who were referred for induced fetal demise from October 2002 to October 2011. We excluded patients undergoing selective fetal reduction in multiple gestations. Procedural complications, the dose of KCl, and the number of failed procedures were determined. RESULTS: Of the 192 completed procedures, 191 were successful (99.5%). The median gestational age at termination was 22 weeks (range, 15.4-24.9 weeks), and most terminations were surgical (68.0%). Major indications for termination were fetal anomalies (41.6%), unwanted pregnancy (20.8%), and aneuploidy (15.7%). The median dose of KCl was 10 mL (range, 3-40 mL). We found a significant correlation between the dose of KCl and estimated fetal weight. There was no significant correlation between the dose of KCl and body mass index or gestational age. We had 1 maternal complication of a seizure after needle placement but before KCl injection.For more Human Toxicity Excerpts (Complete) data for POTASSIUM CHLORIDE (48 total), please visit the HSDB record page. |
