Combined femoral artery block and femoral nerve block reduces thigh tourniquet-induced hypertension
Authors' conclusion
The present study demonstrated that modified femoral nerve block reduced intraoperative esmolol dosage and the incidence of TH.
Study context
- Population
- Patients undergoing high tibial osteotomy under GA
- Participants
- 72 patients
- Comparison
- Modified femoral nerve block vs classical femoral nerve block
- Primary endpoint
- Incidence of tourniquet hypertension (TH)
Methodological detailsprospective, double-blind, single-centre
- Prospective
- Double-blind
- Single-centre
Primary result
As reported in the abstract
Incidence of TH
P = 0.002
Further findings
| Outcome | CFNB | MFNB | P value |
|---|---|---|---|
| Intraoperative esmolol dosage | 65.63 ± 44.15 | 22.19 ± 33.74 | P < 0.001 |
SBP after tourniquet inflation · 45, 60, 75 and 90 min after tourniquet inflation
- SBP significantly higher in classical femoral nerve block (CFNB) than modified femoral nerve block (MFNB) at 45, 60, 75 and 90 min
- P = 0.029, P = 0.020, P = 0.009, P = 0.007
Postoperative pain scores and patient satisfaction
- Not statistically significant between the two groups
