Thiamine and the elderly orthopaedic patient

M W Older, J W Dickerson

    Age and Ageing
    |May 1, 1982
    PubMed
    Summary

    Elderly patients undergoing hip surgery experienced a temporary drop in thiamine (vitamin B1) levels. Thiamine deficiency was prolonged in fracture patients, potentially contributing to postoperative confusion.

    Area of Science:

    • Geriatric Medicine
    • Nutritional Science
    • Orthopaedic Surgery

    Background:

    • Thiamine (vitamin B1) is crucial for neurological function.
    • Elderly patients are at risk for nutritional deficiencies.
    • Surgical stress can impact nutrient status.

    Purpose of the Study:

    • To assess thiamine status in elderly orthopaedic patients post-surgery.
    • To investigate the relationship between thiamine levels and postoperative confusion.

    Main Methods:

    • Two groups of elderly patients were studied: elective total hip replacement (n=30) and femoral neck fracture (n=34).
    • Thiamine status was measured at baseline, 48 hours post-operation, and 14 days post-operation.
    • Cognitive status, specifically confusion, was assessed post-operatively.

    Main Results:

    • Patients undergoing elective hip replacement showed a transient decrease in thiamine status 48 hours post-op, normalizing by 14 days.
    • The majority of patients with femoral neck fractures exhibited thiamine deficiency throughout the 14-day post-operative period.
    • A significant fall in thiamine status was observed in confused patients in both groups.

    Conclusions:

    • Elective hip replacement patients experience a temporary decline in thiamine levels.
    • Femoral neck fracture patients are at high risk for prolonged thiamine deficiency post-surgery.
    • Thiamine deficiency may be a contributing factor to postoperative confusion in elderly orthopaedic patients.
