Abstract/OtherAbstract:
The aim of the study was to investigate Na(+)-course of hip fracture patients in relation to demographic and clinical parameters. Data on 155 older hip fracture patients were analyzed retrospectively. Clinical parameters and serum Na(+) on admission (Na1), during 24h pre-op. (Na2), during 24h post-op. (Na3), and pre-discharge (Na4) were recorded. Hyponatremia and hypernatremia rates pre- and post-operation were 26.5%, 2.6%, 24.5% and 5.8%. Higher Na3 (138.76±4.4mEq/l) vs. Na1 (137.69±4.5mEq/l) (p=0.004) and correlation between age and Na3 (p=0.021) was found. Mean serum Na(+) of impaired mental status (IMS) vs. normal patients and of partially/independent vs. dependent patients were higher (p<0.05). More complications occurred in IMS patients tending to higher Na3 in patients with complications. No differences in Na(+)-courses were found according to sex or co-morbidities. Dysnatremia is highly prevalent in older hip fracture patients. A distinct post-operative increase in serum Na(+) was found, higher in the cognitively and functionally impaired patients. It seems that the Na(+) increase characterizes more IMS patients who suffer more complications, but does not necessarily indicate complications. We recommend surveillance of serum Na(+), particularly in cognitively and functionally impaired older patients in whom the risk of hypernatremia and complications is higher.
