The following are antidotes that should be familiarized by the nurse to respond to this emergency situation quickly. This post will help you familiarize yourself with the common antidotes that are used in the hospital setting. The term antidote is a Greek word meaning “given against”. June 12th.An antidote is a substance that can counteract a form of poisoning. (2018) “The Use of Antidotes for Calcium Gluconate Extravasation: An Experimental Study in Mice”. Pacheco Compaña, F., Míguez, J.M., de Toro Santos, F.J., Centeno Cortés, A., López San Martín, P., Yebra-Pimentel Vidal, M.T. In the histological study, calcium deposits were found in 53% of cases without antidote, 100% of cases with triamcinolone acetonide, 33% of cases with saline solution and 13% of cases with sodium thiosulfate or hyaluronidase.ĬONCLUSIONS: Sodium thiosulfate and hyaluronidase prevent the development of calcium deposits after calcium gluconate extravasation. In the radiographic study, calcium deposits larger than 0.5mm were observed in 40% of cases without an antidote, in 33% with triamcinolone acetonide, in 13% with a saline solution and none at all with thiosulfate and hyaluronidase. RESULTS: Only in the group infiltrated with sodium thiosulfate did all skin lesions disappear after the 3-week period following infiltration. After three weeks, a skin biopsy was performed and a radiographic and histological study carried out. ![]() Five minutes were allowed to lapse after the calcium gluconate infiltration and then an antidote was infiltrated. The substances selected for use in this study were calcium gluconate (4.6 mEq/ml), hyaluronidase (1500 IU/ml), sodium thiosulfate (25%), triamcinolone acetonide (40 mg/ml 0.5 mg/kg) and saline solution 0.9%. METHODS: 74 BALB/c mice were used in the study. The aim of the present study is to analyze the beneficial effects of four possible local antidotes for calcium gluconate extravasation: hyaluronidase, sodium thiosulfate, triamcinolone acetonide and physiological saline solution. The aim of the present study is to analyze the beneficial effects of four possible local antidotes for calcium gluconate extravasation: hyaluronidase, sodium thiosulfate, triamcinolone acetonide and physiological saline solution” Pacheco Compaña et al (2018).īACKGROUND: Calcium Gluconate Extravasation is a process that can cause serious lesions, such as necrosis and calcification of the soft tissues. ![]()
