Association Between Anaemia and Handgrip Strength in Female Planned for Major Surgery and the Effect of Intravenous Iron on Handgrip Strength

November 18, 2020 updated by: University of Malaya

Anaemia and Handgrip Strength, a Prospective Observatonal Study Amongst Female Population Planned for Major Elective Surgery

This is a sub-study parallel to ProPBM : A Randomised Control Trial Comparing a Modified Patient Blood Management Protocol Against Standard Care for Patients Undergoing Major Surgery (NCT03888768).

Only female participants of ProPBM will be included in this sub-study.

Association between anaemia and handgrip strength and the effect of intravenous iron therapy as part of ProPBM protocol within female participants is elucidated in this study.

Study Overview

Detailed Description

BACKGROUND:

Maximal physical efforts and aerobic exercise depend highly on adequate oxygen supply provided by haemoglobin and level of iron bound to haemoglobin.

Handgrip strength has been shown to have a strong validity and high reliability in testing the upper body and lower body muscle strength, however its use as a potential tool to identify early anaemic patients planned for surgery is not fully explored. To our knowledge, this study is the first to investigate the diagnostic power of functional performance test within preoperative anaemic population and the change of handgrip strength after administration of intravenous iron.

METHODS:

At recruitment of ProPBM study, all eligible patients for this sub-study will be invited to this sub-study and have their full blood count, ferritin and transferrin saturation recorded and handgrip strength assessed.

After randomization, those within the ProPBM protocol will receive IV iron therapy as indicated. Participants who are randomized to standard care will follow usual medical management.

Participants will be admitted 1 day prior to surgery. On admission, preoperative bloods and handgrip strength will be repeated for patients who were randomized into the ProPBM arm.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Iron deficiency anaemia
Preoperatively, participants who are iron deficient with or without anaemia will receive intravenous iron (Monofer) as per ProPBM protocol.

The strength of the dominant hand will be recorded before and after receiving intravenous iron.

Each participant will be positioned in a straight back chair with both hand and feet flat on the ground, elbow flexed to 90 degrees with forearm and wrist in the neutral position. Patient's muscle strength will then be tested three times with an interval of one minute between testing and the average of three times will be recorded to the nearest 0.1kg.

Other Names:
  • Handgrip strength
No iron deficiency anaemia
Patient in this group will not be given intravenous iron.

The strength of the dominant hand will be recorded before and after receiving intravenous iron.

Each participant will be positioned in a straight back chair with both hand and feet flat on the ground, elbow flexed to 90 degrees with forearm and wrist in the neutral position. Patient's muscle strength will then be tested three times with an interval of one minute between testing and the average of three times will be recorded to the nearest 0.1kg.

Other Names:
  • Handgrip strength

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Association between handgrip strength and haemoglobin status within female participants of ProPBM study
Time Frame: At recruitment

The dependent variable is concentration of plasma circulating haemoglobin (Hb) taken at recruitment and measured in g/dL.

The non-dependant variable is the baseline handgrip strength recorded in kilogram using Jamar hydraulic hand dynamometer. Participants will be positioned in a straight back chair with both hand and feet flat on the ground, elbow flexed to 90 degrees with forearm and wrist in the neutral position. Patient's muscle strength will then be tested three times with an interval of one minute between testing and the average of three times will be recorded to the nearest 0.1kg.

The association between anaemia and handgrip strength will be analyzed by using binary logistic regression technique.

At recruitment

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Association between handgrip strength and iron status within female participants of ProPBM study
Time Frame: At recruitment

Iron status is measured by ferritin level (mcg/L) and transferrin saturation (percentage value).

Association between iron status and handgrip strength will be analysed using a linear regression technique.

At recruitment
Change in handgrip strength in iron deficient female participants of ProPBM study who received intravenous iron
Time Frame: Handgrip strength repeated within 1 month post IV iron administration preoperatively

Participants who received intravenous iron will have their ferritin level, TSAT and handgrip strength reassesed during preoperative admission.

Handgrip strength after IV iron administration will be compared to baseline handgrip strength.

Handgrip strength repeated within 1 month post IV iron administration preoperatively
