Pain relief after lower limb joint replacement surgery has been a major limiting factor
affecting post operative mobilisation and length of hospital stay. Multimodal local
wound infiltration with local anaesthetics, adrenaline with non steroidal anti
inflammatory agents can lower the opiate intake, reduce the length of stay and
enhance early mobilisation in hip replacement patients. A retrospective review of 30
patients undergoing primary total hip replacement was undertaken. All patients’
wounds were infiltrated with ropivacaine, adrenaline and ketorolac by the operating
surgeon, intra operatively. Subsequently, a 16 G wound catheter placed into the hip
joint. They received two further top up doses of the same combination at 10 hours
and 20 hours postoperatively. This group was compared with a control group of 30
patients who did not receive any local infiltration. Both groups were comparable in
terms of BMI and ASA grades. Post operative opiate drug consumption in first 48
hours after surgery and length of hospital stay were recorded. There was significant
reduction in opiate consumption in the treatment group with an average consumption
of 37.23 mg of morphine compared to 62.73 mg in the control group (P=0.002). The
length of hospital stay was significantly reduced from 5.2 days in the control group to
4.4 days in the treatment group (P=0.02). The patients in the treatment group
mobilised six hours earlier. However, this was not found to be significant statistically.
There were no significant complications in either group.
