Adding an ultrasound-guided iPACK block to an adductor canal block for pain after knee tumor removal

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Adults aged 18–65 with ASA physical status II–IV undergoing excision of tumors around the knee under spinal anesthesia are randomly assigned to receive an adductor canal block plus an ultrasound-guided iPACK block or to a control arm without peripheral blocks. The study measures time to first rescue analgesia, postoperative morphine consumption, and pain on the visual analogue scale (VAS). Standard non-opioid analgesics are given per protocol and morphine boluses are used for VAS >4. The intervention is performed under ultrasound guidance at a single center (National Cancer Institute, Cairo).
