Details and patient eligibility

About

In this study, the minimum effective concentration required for supra-inguinal fascia iliaca block applied in patients undergoing arthroscopic knee surgery is aimed. The same volume will be used in all of the block applications in the study, and the local anesthetic concentration used will be determined by increasing or decreasing according to the success of the previous block. The primary goal of the study is block success.

Full description

For patients included in the study, 40 mL of local anesthetic will be used for SIFIB. The local anesthetic concentration will be randomized using the biased-coin design up-down sequential method, as suggested by Durham et al. and described by Dixon.

The primer outcome of this study is block success. Also, the incidence of motor block formation in the quadriceps muscle (to be defined as paresis or paralysis in knee extension), the amount of tramadol needed in 24 hours, opioid-related side effects (postoperative nausea/vomiting, itching), length of hospital stay and complications that may develop related to the block will be recorded.

Enrollment: 65 patients

Sex: All

Ages: 18 to 65 years old

Volunteers: No Healthy Volunteers

65 participants in 2 patient groups

SIFIB with concentration "A"

Active Comparator group

Description:

The patients were placed in a supine position, and their skin was disinfected and draped. A linear ultrasonography probe was positioned parasagittally and slightly medially on the anterior superior iliac spine. The sartorius, iliacus, internal oblique muscles and deep circumflex iliac artery were visualized. A 80-mm peripheral nerve block needle was advanced, using the in-plane technique, from cranial to caudal until the tip was positioned between the internal oblique and iliacus muscles. Suprainguinal fascia iliaca block will be performed with concentration "A".

SIFIB with concentration "B"

Active Comparator group

Description:
