Abstract [en]

BACKGROUND: Mild to moderately severe dehydration is common in the elderly, but its relationship to surgical outcome is unclear.

OBJECTIVES: To study the incidence of dehydration prior to hip fracture surgery and its relationship to postoperative complications.

DESIGN: Prospective observational study.

SETTING: Operation department and orthopaedic ward at a regional hospital.

PATIENTS: Forty-five patients [median (interquartile range) age 78 (75 to 86) years] undergoing acute hip fracture surgery.

INTERVENTIONS: A urine sample was taken on admission to the operating theatre. Complications were assessed 2 days postoperatively using a check-list.

MAIN OUTCOME MEASURES: Dehydration was considered to be present if the urinary specific gravity was 1.020 or higher, indicating renal water conservation. The number and type of postoperative complications were recorded.

RESULTS: Dehydration was present in one third of the patients. Sixty percent of these patients had at least one postoperative complication, whereas the corresponding proportion was 30% in the euhydrated patients (P <0.01). Only one patient (3%) had more than one complication in the euhydrated group compared with six patients (40%) in the dehydrated group (P <0.01). Euhydrated patients had a mean of 0.3 postoperative complications per surgery, whereas dehydrated patients scored 1.1 complications (P <0.015). The higher incidence included confusion, arterial desaturation and cardiovascular events.

CONCLUSION: Dehydration before surgery nearly quadrupled the number of postoperative complications after hip fracture repair.
