Potassium Preparations
...It is usually added to a solution in which the concentration should generally not exceed 40 mEq of potassium per liter because higher concentrations can lead to pain and sclerosis of a peripheral vein...
Severe Hypokalemia
...In general, the maximum rate of intravenous potassium administration is 10 to 20 mEq per hour, although as much as 40 to 100 mEq per hour has been given to selected patients with paralysis or life-threatening arrhythmias [82]. In these cases, solutions containing as much as 200 mEq of potassium per L (20 mEq in 100 mL of isotonic saline) have been used. They should be infused into a large vein, such as the femoral vein; a central venous line has also been used, but a local increase in the potassium concentration possibly could have a deleterious effect on cardiac conduction.

В панангине в ампуле содержится приблизительно 100 мг калия. Это приблизительно 1,5 мЭкв. Таким образом, разведя его согласно инструкции 10 мл растворителя, можно вполне спокойно вводить в периферическую вену. Но откровенно не знаю, какой дефицит можно восполнить этим, не прибегая к многолитровым инфузиям панангина. Хотя подозреваю, что это отголосок реанимационного шовинизма.
