Analgesia before Performing Subarachnoid Block in the Sitting Position in Patients with Proximal Femoral Fracture: A Comparison between Fascia Iliaca Block and Femoral Nerve Block
Ghimire A, Bhattarai B, Koirala S, Subedi A
Abstract: Background
Positioning for subarachnoid block (SAB) in patients with femoral fracture is painful
and may remain suboptimal requiring use of large doses of opioids. These patients
generally being elderly with multiple comorbidities and frailty are likely to have many
undesirable effects of opioids including respiratory depression and confusion.
Objective
The objective was to compare the feasibility and effectiveness of fascia iliaca
compartment block (FICB) and femoral nerve block (FNB) in reducing pain associated
with positioning for subarachnoid block in patients undergoing proximal femoral
fracture fixation procedures.
Method
Group FICB patients (n=15) received fascia iliaca block with 30 ml of 1.5% lignocaine
with adrenaline and group FNB patients (n=15) received femoral nerve block with 15
ml of 1.5% lignocaine with adrenaline. After the study blocks, patients were kept on
supine position for at least 20 minutes before shifting them to the operation theatre.
Pain was assessed by using visual analog scale values before the block and during
the position for subarachnoid block. Time to perform subarachnoid block, quality of
positioning and acceptance was recorded.
Result
Visual analog scale values during positioning for SAB were lower in FIB group than in
FNB (1.0±1.1 versus 2.1±0.8; P<0.05). Time to perform SAB was shorter in FIB than
in FNB (109.6±28.2 seconds versus 134.8±31.9 seconds; P<0.05). Quality of patient
positioning for SAB was comparable between the groups. Patient acceptance was
less in group FNB (P<0.05).
Conclusion
Fascia iliaca compartment block provides better analgesia than femoral nerve
block in terms of facilitating optimal positioning for subarachnoid block in patients
undergoing proximal femoral fracture fixation procedure.
