Postoperative pain
Conditions
Interventions
The analgesic technique studied was the Pericapsular Nerve Group (PENG block) - G-PENG compared to the PENG block associated with Lateral Cutaneous Femoral nerve block (LFCNB) - G-PENG +CLF. Both bloc

Eligibility
Age
18 Years to No maximum
Inclusion criteria
Inclusion criteria: Patients for elective primary total hip arthroplasty due to coxarthrosis; both genders; age = 18 years; classified by the American Society of Anesthesiologists (ASA) as physical status I or II.
Exclusion criteria
Exclusion criteria: Allergy to local anesthetics; regular use of opioids; diabetes; inflammatory diseases (rheumatoid arthritis, gout, and ankylosing spondylitis); grade II or III obesity (BMI > 35); pregnant women; and patients who received blood transfusion preoperatively, intraoperatively and/or in the first 48 hours postoperatively.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Expected outcome 1: Evaluate postoperative analgesia using the visual analog pain scale (VAS) at 4, 12, 24, and 48 hours. Specifically, the presence and intensity of pain at rest and on movement in the hip and thigh on the operated side will be assessed. To facilitate data analysis and comparison between groups regarding pain intensity, patients will be categorized into bands, according to the maximum pain intensity reported by them in each period. Thus, referred pain from 1 – 3 will be considered mild pain, 4 – 7, moderate pain, and 8 – 10, severe pain. We will observe whether the addition of the lateral femoral cutaneous nerve block (LFCNB) to the pericapsular nerve group block (PENG block) hypothetically reduces pain in up to 48 hours postoperatively in primary total hip arthroplasty surgeries.;Outcome found 1: Evaluate postoperative analgesia using the visual analog pain scale (VAS) at 4, 12, 24 and 48 hours. We found that the addition of the femoral lateral cutaneous nerve block (LFCNB) to the pericapsular nerve group block (PENG block) reduces pain at rest and on movement measured at 4 and 12 hours in the postoperative period of primary total hip arthroplasty surgeries . | — |

The presence and intensity of pain on movement in the hip and thigh on the operated side will be evaluated. Pain on movement was defined as the presence of pain during flexion of the leg and thigh at 30 degrees measured with a goniometer. To facilitate data analysis and comparison between groups regarding pain intensity, patients will be categorized into bands, according to the maximum pain intensity reported by them in each period. Thus, referred pain from 1 – 3 will be considered mild pain, 4 – 7, moderate pain, and 8 – 10, severe pain. We will observe whether the addition of the lateral femoral cutaneous nerve block (LFCNB) to the pericapsular nerve group block (PENG block) hypothetically reduces pain on movement within 48 hours postoperatively of primary total hip arthroplasty surgeries.;Expected outcome 3: Verify the occurrence of a motor block with pericapsular nerve group block (PENG block). In each period, the patient's ability (considered "absence of a motor block") or inability (considered "presence of a motor block") to perform a 30-degree fle | — |
