Of calcium gluconate

Beiran, I., Miller, B., Bentur, Y. The efficacy of calcium gluconate in ocular hydrofluoric acid bums. Hum Exp Toxicol 16(4)), 223-228 (1997)... 

Extreme caution should be used in handling anhydrous HF. It can cause severe bums that may not be noticed immediately but will be very painful later HF dehydrates the skin, and F removes Ca2+from tissues and delays healing. Immediate thorough water washing of any exposed skin should be followed by application of calcium gluconate gel or benzalkonium chloride (trade name Zephiran Chloride), and medical attention is essential. 

Neuromuscular paralysis This side effect most often results after direct intraperitoneal or intrapleural application of large doses of aminoglycosides. The mechanism responsible is a decrease in both the release of acetylcholine from prejunctional nerve endings and the sensitivity of the postsynaptic site. Patients with myasthenia gravis are particularly at risk. Prompt administration of calcium gluconate or neostigmine can reverse the block. 

The label on a bottle of supplements lists all the vitamins and minerals the supplements contain. It also lists the form and source of each vitamin and mineral, and the amount of each. The form of a mineral is especially important to know because it affects the quantity your body can use. For example, a supplement may claim to contain 650 mg of calcium carbonate, CaC03, per tablet. This does not mean that there is 650 mg of calcium. The amount of actual calcium, or elemental calcium, in calcium carbonate is only 260 mg. Calcium carbonate has more elemental calcium than the same amount of calcium gluconate, which only has 58 mg for every 650 mg of the compound. Calcium gluconate may be easier for your body to absorb, however. 

The recovery of calcium gluconate from fermentation broth involves the following. 

AN ORIGINAL BEHAVIOUR OF COPPER(II)-EXCHANGED Y FAUJASITE IN THE RUFF OXIDATIVE DEGRADATION OF CALCIUM GLUCONATE... 

Copper(II)-exchanged Y Faujasite in the Ruff Oxidative Degradation of Calcium Gluconate... 

Copper(II)-exchanged faujasite was tested in the Ruff degradation of calcium gluconate and compared, under the same reaction conditions, with homogeneous catalysis by copper(II) sulphate. The amount of copper was the same in both cases and the reactions were stopped when hydrogen peroxide was totally consumed. D-arabinose and D-erythrose were the main products, glyceraldehyde was formed in small amount 2% yield). Blank experiment was carried out with the starting Na-faujasite, for the same reaction time as the one required for the oxidation in presence of copper zeolite. 

Table 1 Yield of arabinose and erythrose in the oxidative degradation of calcium gluconate by hydrogen peroxide catalysed by Cu(II)-exchanged faujasite. Comparison with homogeneous catalysis,...

When sodium gluconate was used in place of calcium gluconate, copper was always remaining in solution at the end of the reaction. Such a difference of behaviour let to think that the precipitation of calcium carbonate led the precipitation of copper hydroxide when calcium gluconate was used. ... 

CAUTION Fluorine and anhydrous HF can cause severe bums. Before undertaking work of the kind reported here, the experimentalist must become familiar with these reagents. Fresh tubes of calcium gluconate gel should always be on hand for the fast treatment of skin exposed to these reagents. 

Intravenous injection of calcium gluconate can antagonize the cardiac effects of excess potassium. Also, intravenous injection of sodium bicarbonate and glucose will help diminish the effects of potassium hemodialysis overdose, while dialysis can be used to remove excess serum potassium. 

Table VI Influence of the addition of calcium gluconate and glycerol...

I, 1,1 -trichloroethane and other halogenated hydrocarbons are generally supportive and rely on the body s ability to eliminate rapidly 1,1,1-trichloroethane and its metabolites. Animal studies indicate that intravenous injection or infusion of calcium gluconate or phenylephrine are protective against acute blood pressure reduction caused by exposure to 1,1,1-trichloroethane (Herd et al. 1974). Further animal testing is needed to assess whether these compounds might be used to resuscitate individuals exposed to high concentrations of 1,1,1-trichloroethane.
