Registration Number
NCT05543785
Lead Sponsor
Mansoura University
Brief Summary

Tourniquet, a compressing device, otherwise its use in intravenous regional anesthesia, is commonly used in particular orthopedic surgeries. From the previous documented effectiveness and safety of intravenous (IV) administration of ketorolac in the circulatory-isolated limb as a part of intravenous regional anesthesia; we hypothesized that in orthopedic surgeries done with tourniquet, intravenous (IV) administration of ketorolac after tourniquet inflation, will act as intravenous regional analgesia. So, it will prolong the postoperative analgesic duration as a primary outcome.

Detailed Description

This is a randomized controlled trial that tests the effecacy of the intravenous regional ketorolac in lower limb orthopedic surgeries with spinal anesthesia. The investigators will compare the effect of 30 mg ketorolac without local anesthetic in the injected intravenously in an isolated lower limb (with torniquet) versus intravenous 30 mg ketorolac administered 10 minutes before toniquet pressuerization on the postoperative analgesia.

All patients will receive spinal anesthesia aiming for at least T12-L1 level. Postoperative standard analgesia will be paracetamol and diclofenac, given for both groups.

Primary Outcome Measures
NameTimeMethod
The postoperative analgesic durationwithin 24 hours after the surgery

the time measured from the onset of spinal anesthesia to the first request of analgesia by the patient

Secondary Outcome Measures
NameTimeMethod
time to sensory recovery from spinal anesthesiathrough the intraoperative or postoperative care unit

time to receovery of pin brick sensation at S1

time to motor recovery from spinal anesthesiathrough the intraoperative or postoperative care unit

time to modified Bromage score 0

Postoperative pain at restat 2, 4, 6, 12, 24 hours after 24 hours after surgery

0-10 centimetres visual analog scale (VAS) for pain, where zero is equal to no pain and ten indicates the worst possible pain.

Postoperative pain at movementat 2, 4, 6, 12, 24 hours after 24 hours after surgery

0-10 centimetres visual analog scale (VAS) for pain, where zero is equal to no pain and ten indicates the worst possible pain. Movement will be standardized as 10 cm elevation of the surgical limb off the bed.

Total postoperative analgesic consumptionwithin the first 24 hours after surgery

total amount of fentanyl as requested by the patient
