Ultrasound-Guided Interscalene-Supraclavicular Block For An Intramedullary Nailing Of A Pathologic Humeral Fracture: Practical Application Of Ultrasound-Guided Regional Anesthesia, Christian Falyar

Christian R Falyar

Fractures of the proximal upper extremity present a challenge to the anesthesia provider when administering a regional anesthetic because the dermatomal distribution of the upper extremity requires more local anesthetic coverage than any single brachial plexus nerve block can provide. A 60-year-old woman underwent intramedullary nailing of a pathologic humeral fracture using a combination of regional and general anesthesia. This case study shows how ultrasound guidance permitted the performance of both an interscalene and supraclavicular nerve block for a single procedure without the increased volume of local anesthetic that would normally be required, while still providing complete coverage of the …

Anesthesia Of The Geriatric Equine, Reza Seddighi Dvm, Ms, Phd, Dip Acva, Cvma

Reza Seddighi

Advancements in veterinary medicine have resulted in an increased number of geriatric horses being presented for medical or surgical procedures that require general anesthesia. Due to the physiological changes associated with aging and the likelihood of concurrent disease conditions, the geriatric equine is at an increased risk during anesthesia. The main physiological changes associated with aging, and their impact on anesthesia, are discussed in this review.

The Effect Of Midazolam On End-Tidal Concentration Of Isoflurane Necessary To Prevent Movements In Dogs, Reza Seddighi Dvm, Ms, Phd, Dip Acva

Reza Seddighi

Objective To determine the possible additive effect of midazolam, a GABAA agonist, on the end-tidal concentration of isoflurane that prevents movement (MACNM) in response to noxious stimulation. Study design Randomized crossover experimental study. Animals Six, healthy, adult intact male, mixed-breed dogs. Methods After baseline isoflurane MACNM (MACNM-B) determination, midazolam was administered as a low (LDS), medium (MDS) or high (HDS) dose series of midazolam. Each series consisted of two dose levels, low and high. The LDS was a loading dose (Ld) of 0.2 mg kg-1 and CRI (2.5 μg kg-1 minute-1) (LDL), followed by an Ld (0.4 mg kg-1) and …

This article describes the rationale behind the use of systemically administered lidocaine as an analgesic. The analgesic efficacy of intravenously administered lidocaine is well documented by studies in human patients and laboratory animals. The mechanism by which systemically administered lidocaine produces analgesia is uncertain but is thought to include action at sodium, calcium, and potassium channels and the N-methyl-D-aspartate acid receptor. …
