Application of colloidal-hyperosmolar solution in the early postoperative period in patients after cardiosurgery
Objective. To substantiate the safety of the infusion drug Hecoton in the early postoperative period in patients after cardiac surgery.
Materials and methods. The study involved 60 patients receiving infusions of 200 ml colloid-hyperosmolar solution Gecotone. The solution contains: hydroxyethyl starch 130/0.42 – 5 %, polyatomic alcohol xylitol – 5 %, sodium lactate – 1.5 % and electrolytes Na+, K+, Ca++, Mg++, Cl-. The total amount of sodium in the solution is 270 mmol/l, which is 2 times higher than its concentration in blood plasma. The amount of lactate is 133 mmol/l, which is 4 times higher than in isotonic polyelectrolyte solutions. The total osmolarity of the drug is 890 mOsm/l. Vital signs, hemodynamics, glucose, arterial blood gas and acid-base status was evaluated before, during and infusion of medication.
Results and discussion. Gecoton infusions had no adverse effect on hemodynamic parameters. All changes were not statistically significant. The mean values of the patient’s body temperature were within the normal range. There was no case of temperature increase above 36.9 °C in all patients after administration of the drug. There was a slight, statistically unreliable increase in the mean glucose level (from 8.57±0.42 to 9.53±0.48 mmol/l), which was most likely due to response to the surgical stress. Dynamics of arterial blood gas and acid-base state shows that pH and PaCO2 practically did not change, decrease of PaO2 from 115.69±5.52 mm Hg to 110,79±4,83 mm Hg after the infusion of Gecotone, was statistically unreliable, the base excess showed little dynamics to increase (from -1.84±0.35 to -1.29±0.23 mmol/l) after administration of Gecotone.
Conclusions. The use of the complex colloid-hyperosmolar infusion solution Gecotone in patients after cardiac surgery in the early postoperative period is safe.
