Analgesia
Conditions
Brief summary
The aim of this study is to evaluate the analgesic efficacy of fascia iliaca compartment block using bupivacaine versus bupivacaine with dexamethasone or magnesium sulphate for dynamic hip screw surgery under spinal anesthesia. The primary outcome will be the duration of effective analgesia from FICB till the first analgesic dose is required,the secondary outcomes will be the severity of postoperative pain as will be assessed by the visual analogue scale and the total dose of pethidin for rescue analgesia.
Detailed description
Different modes of analgesia are given prior to neuraxial blockade for pain relief like non-steroidal anti-inflammatory drugs (NSAID), opioids and peripheral nerve blocks such as, femoral nerve block, 3 in 1 block or fascia iliaca compartment block (FICB). FICB is believed to be most beneficial compared to other procedures because of its safety and efficacy . FICB provides blockage of at least two of the three major nerves that supply the medial, anterior and lateral thigh with one simple injection, namely the femoral and lateral femoral cutaneous nerves. FICB is an anterior approach to the lumbar plexus. The pop technique using fascial click had a low success rate of 35% - 47% .However, as the FICB was performed under real-time ultrasound guidance, the success rate was increased up to 82- 87%, leading to an increased interest in FICB as a postoperative analgesia option for hip and knee surgical procedures .
Interventions
DRUGBupivacaine
Ultrasound guided fascia iliaca compartment block (FICB) will be performed using 28 ml bupivacaine 0.25% + 2 ml of normal saline (total volume 30 ml).(
DRUGDexamethasone/bupivacaine
Ultrasound guided fascia iliaca compartment block (FICB) will be performed with 28 ml bupivacaine 0.25% + 2 ml dexamethasone (8mg) (total volume 30 ml)d using
DRUGMagnesium Sulfate/bupivacaine
Ultrasound guided fascia iliaca compartment block (FICB) will be performed using 28 ml bupivacaine 0.25% + 2 ml magnesium sulphate (200mg) (total volume 30 ml).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Analgesia | duration from the end of surgery till the first time to ask for post operative analgesia within the first 12 hours after surgery | the duration of effective analgesia will be considered as the duration after performing the FICB till the patient ask for first analgesic dose ,in this case pethidin 25 mg will be given intravenously |
