Augat P Abstract The force experienced while inserting an 18-gauge Tuohy needle into the epidural space or dura is one of only two feedback components perceived by an anaesthesiologist to deduce the needle tip position in a patient's spine. To the best of the authors knowledge, no x-ray validated measurements of these forces are currently available to the public. A needle insertion force recording during an automated insertion of an 18-gauge Tuohy needle into human vertebral segments of four female donors was conducted. During the measurements, x-ray images were recorded simultaneously. The force peaks due to the ...

Authors: Yamak Altinpulluk E, Turan A Abstract Regional anesthesia has a very interesting long history, initially preferred over general anesthesia because of safety concerns, then for a period general anesthesia became safer and was preferred. The use of innovative technologies such as ultrasound technology has made the blocks safer and successful by directly visualizing targeted nerves and the location of local anesthetics. With the wide use of ultrasound in the regional anesthesia field success rate of peripheral nerve blocks increased and novel blocks techniques developed. Moreover, new extended-release local a...

Authors: Chun Y, Phillips M, Suresh S Abstract Regional anesthesia has grown in popularity as a multimodal approach to analgesia. However, some anesthesiologists are fearful of regional blocks in pediatric patients as most require general anesthesia. One of the most alarming complications is neurologic injury. While there are limited case reports regarding the devastating neurologic injuries in pediatric patients, review of large databases has shown a level of safety in pediatric regional anesthesia that is comparable to that in adult patients. This review aimed to provide an update on the relevant literature regar...

AbstractThe aim of this study was to determine the effect of an aerosol box on tracheal intubation difficulty. Eighteen experienced anesthetists intubated the trachea of a manikin with a normal airway 6 times using a direct laryngoscope, a McGRATH ™ MAC videolaryngoscope, or an airway scope AWS-S200NK videolaryngoscope with or without an aerosol box. Although the aerosol box prolonged the time to successful intubation and decreased the percentage of glottic opening (POGO) score when using a direct laryngoscope, the statistically significant differences were clinically irrelevant. When a McGRATH™ MAC and an AWS-...

Authors: Huang L, Fang HB, Cheng HH, Mei SL, Cheng YP, Lv Y, Meng QT, Xia ZY Abstract Isoflurane is a broadly used inhalation anesthetic that causes cognitive impairment in rodent models as well as humans. Although previous studies suggested an association between isoflurane exposure and neuro-inflammation, apoptosis and mitochondrial dysfunction, the pathogenesis of isoflurane-induced cognitive decline remains elusive. In the present study, 22-month-old male Sprague-Dawley male rats (n=96) were divided into three groups: Control (Cont), isoflurane (ISO) and MS-275 pre-treated groups. The rats were sacrificed follo...

I've heard this nonsense before and came across it again today. Had a PTA and cut the back of this throat and didn't get anything. I was frustrated and ENT kindly came in and literally aimed 1 mm caudal from my incision and took out 10 cc pus! So frustrated. So I asked ENT why didn't you numb the back of the throat? She said it doesn't work because lidocaine doesn't anesthesize in acidic environments. I mean this is nonsense! I anesthesize abscesses on external body parts all the... Lidocaine doesn't work in an acidic environment

okra Andrea Calkovska The study aimed to prove the hypothesis that exogenous surfactant and an antibiotic polymyxin B (PxB) can more effectively reduce lipopolysaccharide (LPS)-induced acute lung injury (ALI) than surfactant treatment alone, and to evaluate the effect of this treatment on the gene expression of surfactant proteins (SPs). Anesthetized rats were intratracheally instilled with different doses of LPS to induce ALI. Animals with LPS 500 μg/kg have been treated with exogenous surfactant (poractant alfa, Curosurf®, 50 mg PL/kg b.w.) or surfactant with PxB 1% w.w. (PSUR + PxB) and mechanically ventila...
