Analgesic efficacy of posterior and anterior psoas compartment block: Lumbar plexus versus three -in-one nerve block after lower limb orthopedic surgery under spinal anesthesia: A prospective cohort study

The comparison of postoperative analgesic efficacy of three-in-one-block versus fascia-iliaca blocks following femoral fracture orthopedics surgical procedures under spinal anesthesia, Gondar, Ethiopia, 2021: A prospective cohort study

INTRODUCTION

Femoral bone fracture is the predominant, lower limb orthopedic surgery that is associated with severe acute and persistent chronic pain that needs better postoperative pain management. Untreated postoperative pain results inability to do physiotherapy resulting in stiffens of joints and immobility. This study aimed to compare the postoperative analgesic efficacy of three-in-one-block versus fascia iliaca block in patients who underwent surgically treated femoral fractured patients under spinal anesthesia.

METHODS

A prospective cohort study was conducted on 110 elective surgically treated femoral fractured orthopedic patients from January to October 2021. Data were entered into epi-data 4.4.2 and imported into a statistical package of social science version 22 for analysis. Shapiro-Wilk normality test was used to check the normality of the data and normally distributed data were analyzed using Student's independent t-test, whereas non-normally distributed variables were analyzed with Mann-Whitney U-test. The comparisons of categorical parameters were analyzed using the chi-square test and Fisher's exact test. Finally p-value < 0.05 was declared to be statistically significant.

RESULT

The median and interquartile range of the postoperative numerical rating scale at rest and on movement was significantly less in three-in-one-block (3IN1B) as compared with fascia-iliaca block (FICB). But at 30 min no significantly different between the two pain management modalities. Moreover, the meantime to seek the first request of analgesia was significantly prolonged in 3IN1B compared with FICB. Regarding the total analgesic consumption, the mean total tramadol consumption was 97. 27 ± 53. 07 and 180 ± 72.96 (p < 0.001) and Diclofenac 53.18 ± 29.28 and 72 ± 43.54 (p < 0. 001) in 3IN1 and FICB, respectively.

CONCLUSION

The present study concludes that three-in-one-block provides more effective analgesia, reduced postoperative analgesic requirements, and prolonged first analgesics requests compared with fascia iliaca block, and Landmark technique fascia-iliaca block (FICB) is an alternative pain management modality in a resource-limited setting.
