The clinical efficacy of a continuous psoas compartment - sciatic nerve block in patients undergoing a total hip arthroplasty.

A psoas compartment - sciatic nerve block (psoas compartment - sciatic nerve
block = PCSNB) is a widely used proximal peripheral nerve block in orthopedic
surgery at the lower extremity. Particularly in the proximal lower extremity
surgery, including hip surgery, this technique can be of great value as part of
postoperative pain management strategy. Recently, the clinical efficacy of a
single-injection PCSNB with long-acting local anesthetics in patients
undergoing total hip prosthesis had been analyzed. One of the conclusions from
this study was a modification of this single - injection PCSNB was desirable
given the fact that the sensory blockade is not the whole wound area belonging
to the total hip prosthesis covered. According to this modification, the
authors suggested a continue PCSNB, itt analyzed, single-injection, technique
for this kind of surgery. This continuous PCSNB, where there is a catheter is
left in the vicinity of the plexus lumbosacralis, creates the opportunity for
greater local anesthetic volumes per unit time in order to submit a more
comprehensive blockade to achieve

The aim of the present, observational, descriptive, pilot study is the clinical
efficacy (expressed in pain scores, sensory and motor blockades) of continuous
PCSNB analysis in which patients undergo a total hip prosthesis.

observational, intervention study without invasive postoperative measurements.

Psoas Compartment - Sciatic nerve block.

Risk: very low, the risks associated with the continuous peripheral nerve
blockades.

Tax: very low, being non-invasive, postoperative testing.

Study outcomes are very valuable concerning clinical efficay assessment.
