Factors determining the post-operative hypo-albuminaemia in cancer patients--stepwise regression analysis

To investigate factors influencing post-operative hypo-albuminaemia in cancer patients, with special reference to low dose albumin and/or immunoglobulins administration.

In 270 patients with malignant neoplasms, who underwent extensive chest and/or abdominal surgery, albumin concentrations on the first four postoperative days were examined. One hundred and three high-risk patients received human immunoglobulins intravenously; 44 were given albumin. Univariate and multivariate regression analyses were used to determine the factors influencing albuminaemia on the first four postoperative days.

Mean nadir of hypo-albuminaemia occurred on the third postoperative day. In the multivariate analysis, a positive correlation was found between postoperative albuminaemia and pre-operative albuminaemia (b = 0.4919; p = 0.0000) as well as male gender (b = 2.0939; p = 0.0025). A negative correlation was found with the duration of surgery (b = -0.0416; p = 0.0212), pre-operative plasma protein (b = -0.2118, p = 0.0130) and postoperative immunoglobulin administration (b = -1.8858, p = 0.0074).

Postoperative albuminaemia is positively correlated with pre-operative albuminaemia and male gender and negatively correlated with the duration of surgery, pre-operative proteinaemia and postoperative Ig administration.
