NYSORA.com is my go-to for any question on RA. I’ve been to a couple of workshops as well - definitely worth every penny.

I’ve been practicing anesthesia for more than thirty years, and regional for more than 10. I trust NYSORA to get my info from and follow everything new they release. My favorite source.

What is the best block for proximal Humerus fracture fixation 

Ivan Keser

I am very happy that I managed to organize the “First Regional Anesthesia Workshop under Ultrasound Control” at the General Hospital in Sarajevo.

This one-day workshop was intended both for beginners who want to learn the basics and for those who want to improve their skills in ultrasound-guided regional anesthesia.

I would like to thank all the participants for their hard work and engagement. I am sure that all of them will be able to immediately apply the acquired knowledge in their practice.

I would also like to thank Dr. Hadzic, thanks to his mentorship and opportunity to have a unique learning experience with him I was able to organize and successfully implement this workshop.

I have a couple of questions regarding the PENG/hip block

1) Some of our orthopedic surgeons are very skeptical to PENG blocks due to a fear of prosthetic infection. From a letter to RAPM (2019;44;257) Tran (and Peng himself) shares images of dye PENG blocks in a cadaveric model and that it stains across the anterior capsule (so, surgery site close) even with 10ml (though this is where the branches we are targeting exist, so…). I’ve not found any studies addressing this (apart from a secondary outcome in a RCT of S-FICB vs PENG with a mere 27 patents in each group, no SSI in either group, see reference below). Is this a valid concern, or are there anatomic reasons why this should have low risk of infection?

2) I see from a post by Dr Hadzic on this forum that he uses 15ml. The forementioned study on S-FICB vs PENG used 20ml and found the same decrease in quadriceps strength, possibly due to spillover of LA to the femoral nerve. The Letter to the editor used only 10ml in one of the specimens and found adequate spread. Those of you who do 15ml, do you still see quadriceps weakness (and problems with mobilization of the patients post op). Does anyone have experience with using only 10mls? Our ortho surgeons are extremely focused on the early(ish) mobilization part and thus are very against any blocks for THA (our FCF hemi’s do get FICBs)

Hello, let me kindly ask you, how do you treat total knee arthroplasty in your hospital? I red dozen papers on internet, but want to try different approach, as a newbie in periferal block anesthesia.

These days we do it in continual epidural anesthesia for two days. It means, L1/L2 epidural cateter 20G to 4cm deep via Touy needle 18G, kapilary test for epidural space placement approval, anesthetic dose bolus (2%Lidocain 10ml+0,5%Marcain 10ml+10mcgSufentanil (2ml) -> then one hour after beginning of the procedure starting a continual epidural infusion via NRFit lock safe system 3-8ml/hod. (12ml 0,5%Marcain+10ml(50mcg)Sufentanil+38mlF1/1=>V60ml)

Thank You for Your comments 🙏🏼
