Relationship between serum lactate and ionized calcium in open-heart surgery.
We studied 16 patients undergoing open-heart surgery and heart-lung bypass, to examine the relationship between ionized calcium and lactate. Blood was sampled at successive stages of the operation for measurement of ionized and total calcium, lactate, blood gases, pH, hematocrit, and other constituents. We found that correlations between ionized calcium and lactate were positive and statistical...
متن کاملSimple method for estimating plasma hemoglobin during open heart surgery.
Standard methods to measure plasma haemoglobin use orthotolidine or benzidine. These have disadvantages of (a) being time consuming, (b) depending for accuracy on critical timing of colour development, and (c) both compounds are considered to be carcinogenic. Some laboratories give an approximate result, e.g., a one, two, or three plus degree of plasma haemoglobin. In estimating plasma haemoglo...
متن کاملPatterns of total and ionized calcium and other electrolytes in plasma during and after general surgery.
Thirteen patients were studied during two hours of anaesthesia for abdmonial operations and for an hour post-operatively. Serial venous blood samples were taken for determination of plasma total and ionized calcium, acid-base variables, Na, K, Mg, PO4 total proteins and parathyroid hormone. One group of patients received 5 per cent dextrose/water and the other 5 per cent dextrose in Ringer's so...
