Improper use of it will still cause adverse reactions of varying degrees, such as nausea, fever, vomiting, chills, palpitations, etc. In severe cases, it may also lead to serious consequences such as local tissue necrosis, anaphylactic shock, and acute laryngeal edema, threatening Patient’s life safety.
How can we avoid or reduce the occurrence of adverse reactions?
Choosing the right medication is one of the solutions. At present, Calcium Gluconate Powder is mainly administered in two ways: intravenous injection and intravenous drip. Among them, intravenous drip is often used for large volume infusion, and intravenous bolus is mostly used for small volume liquid injection. Clinical studies have shown that intravenous bolus injection increases the probability of serious adverse reactions.
What could be the reason?
On the one hand, the static push speed is not easy to control, which may cause arrhythmia in patients. On the other hand, intravenous boluses may increase drug extravasation, which may subsequently cause desquamation and tissue necrosis. The focus of reducing the occurrence of adverse reactions is to control the injection speed, dilute the concentration of the drug solution and prolong the administration time.
The intravenous injection speed is relatively fast, and the calcium concentration in the blood suddenly rises. High calcium affects the cardiovascular system and other tissues and organs, and various adverse reactions are prone to occur, such as dizziness, headache, nausea, vomiting, chest tightness, arrhythmia, tachycardia Bradycardia, arrhythmia, etc. In severe cases, ventricular fibrillation and severe atrioventricular block will occur. If not rescued in time, the patient’s life may be endangered.
The speed of intravenous drip injection is controlled at 20-30 drops/minute, the calcium agent enters the blood relatively slowly, and the blood calcium will not suddenly rise in a short period of time, so the adverse reactions are significantly reduced.
On the other hand, during the intravenous injection of calcium gluconate, the general nurse is at the bedside, and can deal with it in time when adverse reactions occur. However, during the intravenous infusion of calcium gluconate, most of the nurses are not around. Once adverse reactions are found, they cannot be corrected and treated in time. .
Therefore, how to choose the usage of Calcium Gluconate Powder in clinical practice should be determined according to the specific situation.
If it is used to supplement calcium, you can choose intravenous infusion.
If it is used to control emergencies such as hypocalcemia spasm and numbness around the mouth of the hands, feet, you can choose to inject calcium gluconate intravenously as soon as possible within a safe range.
