Clinical Trial Summary

The investigators aimed to demonstrate that dexamethasone added as an adjuvant to local anaesthetic agent in suprainguinal fascia iliaca block for effective postoperative analgesia after knee arthroplasty would prolong the duration of sensory block and reduce postoperative pain intensity and analgesic consumption.

Description:

Total knee arthroplasty is one of the major orthopedic surgeries that cause severe postoperative pain. A successful post-operative outcome is possible with strong and effective pain control followed by early mobilization and a good functional recovery. Suprainguinal fascia iliaca plan block (SFIB) has been shown to be an effective postoperative method in multimodal analgesia regime in lower extremity surgery. It has been reported in the literature that dexamethasone added to local anaesthetics in peripheral nerve blocks prolongs the duration of sensory block, improves the quality of analgesia, reduces postoperative pain intensity and opioid consumption.

In this study, the investigators aimed to demonstrate that dexamethasone added as an adjuvant to local anaesthetic agent in SFIB for effective postoperative analgesia after knee arthroplasty would prolong the duration of sensory block and reduce postoperative pain intensity and analgesic consumption.

An identification number will be randomly assigned to each participants, whose written consent was obtained before the surgery, when they are admitted to the postoperative recovery room. In the postoperative period, participants will be followed up with these numbers. Which group the participants will be included in will be determined by the closed envelope method.

Participants undergoing unilateral knee arthroplasty will be included in the study. Following the end of surgery, the participants will be divided into two groups in the recovery room and SFIB will be applied to both groups. Participants in group SFIB will receive 0.25% bupivacaine as local anaesthetic. Participants in group SFIB+dexamethasone will receive 0.25% bupivacaine as local anaesthetic and 8 mg dexamethasone as adjuvant.

The participant with the block will be followed in the recovery room and if the block is successful, morphine patient controlled analgesia (PCA) treatment will be started and the participant will be taken to the ward. A standard analgesia regimen (1 g iv paracetamol every 8 hours, 50 mg iv dexketoprofen every 12 hours) was used in all participants.

Evaluation of postoperative pain will be done with numerical rating scale (NRS). Pain levels will be questioned in two different ways as rest and passive moving.

Related Conditions & MeSH terms

• Pain, Postoperative
• Regional Anesthesia

Intervention

Procedure:
• Suprainguinal fascia iliaca block
After the operation is completed, the fascia iliaca will be separated from the iliacus muscle. With ultrasound guidance, the local anesthetic injection will be made between the fascia and the muscle.
• Suprainguinal fascia iliaca block+dexamethasone
After the operation is completed, the fascia iliaca will be separated from the iliacus muscle. With ultrasound guidance, the local anesthetic+dexamethasone injection will be made between the fascia and the muscle.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Postoperative opioid consumption	First 24 hours total morphine consumption with patient controlled analgesia	Postoperative 24 hours
Secondary	Numerical Rating Scale	To determine the pain of the patients at rest and passive-active moving at the 1st, 3rd, 6th, 12th, 18th and 24th hours postoperatively with Numerical Rating Scale (NRS).The NRS is a segmented numerical version in which the respondent selects an integer (0-10) that best reflects the intensity of their pain. 0: no pain 1-3: mild pain 4-6: moderate pain 7-10: severe pain.	Postoperative 24 hours
Secondary	Timed up and go test (TUG)	TUG- evaluation of the time in seconds for the patient to get up from the chair and walk 3 meters and return to the chair again	at 24th hour
Secondary	Quadriceps muscle strength	will be evaluated in a scale between 1-5 (1:lowest; 5:normal)	at 24th hour
