of other commercial ultrasound gels has not produced allergic reactions in this subject. Propylene glycol (1,2-Propandiol 1,2-Dihydroxypropane) is a bivalent alcohol and acts as a bacteriostatic dissolver, moisturizer, and preservative. Because of its low molecular weight and 2 hydroxyl groups, it easily penetrates the skin and it is widely used in many cosmetic products. Propylene glycol is well described as a contact sensitizer.3,6,7 Other substances in ultrasonic gels can cause allergic… Expand

Minimum effective local anesthetic volume for surgical anesthesia by subparaneural, ultrasound-guided popliteal sciatic nerve block
TLDR
The MEV of ropivacaine 0.75% for induction of surgical anesthesia by the method of US-guided popliteal sciatic nerve block via subparaneural injection is determined to decrease the risk of local-anesthetic systemic toxicity (LAST). Expand
A Randomized Comparison Between Bifurcation and Prebifurcation Subparaneural Popliteal Sciatic Nerve Blocks
TLDR
When local anesthetic is injected inside the paraneural sheath, B and PB posterior popliteal sciatic nerve blocks result in comparable success and total anesthesia-related times, however, in light of the 95% CIs, the possibility that an intergroup difference of 19% and 7.83 minutes might have gone undetected for success rate and total time is not excluded.

Soft tissue landmark for ultrasound identification of the sciatic nerve in the infragluteal region: the tendon of the long head of the biceps femoris muscle
TLDR
The present study recognized a hyperechoic structure at the medial border of the long head of biceps femoris muscle that could be a potential internal landmark to identify the infragluteal sciatic nerve. Expand

Allergic contact dermatitis due to Euxyl® K 400 in an ultrasonic gel
TLDR
Preservatives are widely used in medical preparations to achieve asepsis and Euxyl® K 400 is incorporated in leave-on cosmetics, shampoos, liquid soaps and other rinse-off products, and topical medicaments, and metalworking fluids may also contain it. Expand

TLDR
This case suggests that one should keep in mind the possibility of an anaphylactic reaction to ultrasonographic gel, especially when the substance is used in contact with mucosa, as it is observed that a 44 year old woman after transvaginal ultrasonography showed malaise and hypotension. Expand
Ultrasound guidance for a lateral approach to the sciatic nerve in the popliteal fossa
TLDR
This case is presented in which ultrasound imaging was used for a lateral approach to the sciatic nerve in the popliteal fossa and injected local anaesthetic was seen on ultrasound as it spread around both tibial and common peroneal nerves. Expand
