Serum electrolyte concentrations during two days post-laparotomy infusion of saline, glucose or amino acids in rabbit.
The changes in serum sodium, potassium, chloride, calcium, and phosphorus concentrations during 48 hours post-laparotomy infusion of saline, 10 percent glucose alone, and in combination with two different amino acid solutions were investigated in the rabbit. Most of the changes occur 24-hours after the laparotomy. The changes of serum potassium concentration are different from those of chloride, sodium, calcium, and phosphorus. The quality of infusion does not change the direction of the post-laparotomy change of the serum chloride (increase) and calcium (decrease) concentration. The serum potassium concentration increases and phosphorus remains constant when saline is infused, whereas potassium remains constant and phosphorus decreases when the other solutions are given. The responses to the different infusions are most diversed in the case of sodium. The serum electrolyte concentrations remain at the level of the 24-hours post-laparotomy state also after the 48-hours infusion, with the exception the decrease of potassium during saline, increase of sodium during glucose and amino acid and increase of calcium during glucose infusion.
