Abstract

OBJECTIVE The objective of this prospective randomized controlled study was to investigate the effect of nutritional supplementation on postoperative oxidative stress and duration of hospitalization in elderly patients with hip fracture METHODS A total of fourteen women = SG with hip fracture received individually adapted supplements enriched with protein and antioxidants postoperatively nine served as unsupplemented controls = CG Blood samples were taken preoperatively T1 on the day of discharge from hospital T2 and three weeks thereafter T3 Plasma concentrations of albumin and total protein TP were measured by autoanalysis advanced oxidation protein products AOPP and the total antioxidant capacity TAC were determined photometrically Malondialdehyde MDA levels were analyzed by HPLC RESULTS Postoperatively there was a significant T1 T2 p 001 decrease in plasma albumin TP and TAC followed by a significant p 005 increase in the period T2T3 in the CG but not in the SG This resulted in significant differences in TP T2 SG CG p 005 and TAC T2 SG CG p 001 between the investigated groups Postoperatively the plasma levels of AOPP and MDA increased significantly T1 T2 p 001 in both groups and remained at the significantly AOPP T1 T3 p 005 MDA T1 T3 p 001 elevated level in the CG but not in the SG T2 T3 p 001 Consequently the oxidant markers MDA and AOPP were significantly positively p 001 TAC and albumin significantly negatively p 005 related to duration of hospital stay in both groups CONCLUSIONS Individualized nutritional supplementation may reduce postoperative oxidative stress and shorten duration of hospitalization in patients with hip fractureZIELSETZUNG Ziel dieser prospektiven randomisierten kontrollierten Studie war es den Effekt einer gezielten Ernährungsintervention auf den postoperativen oxidativen Stress und die Krankenhausaufenthaltsdauer bei Hüftfrakturpatienten zu untersuchen METHODEN Vierzehn Patienteninnen Interventionsgruppe = SG erhielten postoperativ eine individuell angepasste Nahrungsergänzung mit Protein und Antioxidantien neun Patientinnen ohne Ernährungstherapie bildeten die Kontrollgruppe = CG Blutproben wurden präoperativ T1 am Tag der Entlassung T2 und drei Wochen T3 danach gesammelt Die Plasmakonzentrationen an Albumin und Gesamtprotein TP wurden mittels Autoanlyzer bestimmt Advanced Oxidation Protein Products AOPP und die Totale Antioxidative Kapazität TAC wurden photometrisch Malondialdehyd MDA mittels HPLC analysiert ERGEBNISSE Während die Plasmakonzentration an Albumin TP und TAC innerhalb der SG postoperativ konstant blieb wurde in der CG eine signifikante Reduktion T1T2 p 001 dieser Parameter welche nach der Phase T2–T3 wiederum das Ausgangsniveau T2 T3 p 005 erreichten erfasst Dies resultierte in signifikanten Differenzen von TP T2 SGCG p 005 und TAC T2 SGCG p 001 zwischen den untersuchten Gruppen Weiters zeigte sich postoperativ in beiden Gruppen ein signifikanter Anstieg der Plasmaspiegel an AOPP und MDA T1 T2 p 001 welche im weiteren Studienverlauf in der CG AOPP T1 T3 p 005 MDA T1 T3 p 001 nicht jedoch in der SG T2T3 p 001 signifikant erhöht blieben MDA and AOPP korrelierten in beiden Gruppen signifikant positiv p 001 TAC und Albumin signifikant negativ p 005 mit der Krankenhausaufenthaltsdauer SCHLUSSFOLGERUNGEN Individuell angepasste Supplementation mit Nährstoffen kann das Auftreten von postoperativem oxidativen Stress verringern sowie die Krankenhausaufenthaltsdauer bei Hüftfrakturpatienten verkürzen
