Sorry. I'm a Portughese anesthetist and I don't know what is Clexane. Can you explain what is it? thank you

A single shot ciatic block is very good for this situation, with a continuous femural block

To importants thinghs: in children always asleep, in adults we perform in most of the cases with the patient talking with us. But I think, no problem if the current is >0.4 mAmp and more importante is the pression in the plunger of seringe

The minimal current in my hospital is 0.4 mAmp, except in diabetic patients , 0.6 or more . But 0.3 is fine, take attention only with a pression when you inject de local anesthetic! High pression is a bad sign

Good nigth. sorry my bad English

1 - I prefer femural block with a stimulating catheter and a continuous infusion with a elastomeric pump to Total Knee replacement, with GA or SAB.
2 - For Hip replacement I do weekly a posterior approach lumbar plexus , with a stimulating catheter for analgesia with a SAB .

Good results

why thoracic epidural! more local anesthetic, more problems. Lumbar epidural in this situacion is better in my opinion.Best regards

In ortopedic surgery ( hip trauma ), first I perform a femural block, with 25 ml of ropivacaíne 0.5% and 10 or 15 minutes later I  perform a SAB, with a bupivacaíne isobaric ( 7,5 mg ) and fentanil 12,5 ug , with the fractured hip upperside with no problem, and no hypotension. Sorry my bad English
