Is estimated peri-operative glomerular filtration rate associated with post-operative mortality in fractured neck of femur patients?
AIM: Comparison of renal function in patients who died within 30 days of surgery for hip fractures with surviving patients matched for age, type of surgery, type of anaesthesia and clinical assessment of fitness for surgery. MATERIALS & METHODS: A retrospective case-control study of 80 patients was performed. Pre- and post-operative urea, creatinine, estimated glomerular filtration rate (eGFR), sodium and potassium of 40 patients who died within 30 days post-surgery (cases) were compared with 40 patients who survived matched for age, sex, surgical procedure and pre-operative ASA grade (controls). Statistical analysis involved univariable analysis by paired t-test and logistic conditional regression analysis. RESULTS: Pre- and post-operative mean serum creatinine were significantly higher in patients who died compared with surviving controls (pre-op 108.2 vs. 90.2 micromol/l [p=0.002], post-op 103.9 vs. 87.1 micromol/l [p=0.003]). However, mean creatinine values for both groups were sti
