Abstract
BACKGROUND: The scarcity of mortality data in our country led to systematic effort with aim of evaluating peri-operative parameters associated with mortality in hip arthroplasties to determine better fixation method and reducing avoidable variables. MATERIALS & METHODS: 252 consecutive patients (133 males and 119 females; Mean age 58.68 years) operated for hip arthroplasties (cemented & uncemented THR and bipolar hemiarthroplasty) were observed prospectively for 2 years. Heart-rate, O2 saturation and BP were recorded at specific surgical steps and post-operatively for 48 h. Post-operative Trop-T and 2D Echocardiography were done in all patients and D-Dimer and CTPA in indicated ones. All post-operative deaths were extensively studied. RESULTS: - Majority (63%) were operated for traumatic indications.48% belonged to ASA grade-1, 46% grade-2 and 4% grade-3. There was statistically significant association of diagnosis (traumatic aetiology), ASA grade 2, raised Troponin -T, raised D-dimer and pulmonary embolism with mortality. Mortality rate in our study at post-op 48 h was 5.5%, 30 day- 8% and 1-year mortality rate was 19%. With total of 14 deaths, 8 deaths (57.14%) occurred among 127 cemented arthroplasties and 6 deaths (42.86%) among 125 uncemented arthroplasties. CONCLUSIONS: Selection of implant (cemented or uncemented) made no difference in eventual mortality. Collaborative effort of orthopaedic surgeon, anaesthetist and experts from respective fields in elderly high-risk patient with vigilant post-operative surveillance for minimum 48 h would help in lowering mortality associated with hip arthroplasties.
