BACKGROUND: Local anaesthetics (LA) are often suspected as possible causes of allergic reactions. The Danish Anaesthesia Allergy Centre (DAAC) is the national reference centre for investigation of perioperative allergic reactions. The purpose of this study was to investigate the incidence of IgE-mediated immediate type perioperative allergic reactions to LA. METHODS: In the period 2004-2013, a total of 409 patients (244 women/165 men; median age 49 years, range 1-86 years) were investigated in DAAC on suspicion of allergy associated with anaesthesia and surgery...

BACKGROUND: Saphenous nerve block contributes to analgesia after knee and lower leg surgery. However, literature reports a wide range of volumes of local anaesthetic being used for this block. METHODS: A non-randomized controlled trial in a single university hospital in March 2015. Eighteen healthy volunteers (ASA 1 status, aged 27-43 years; male/female ratio 11 vs. 7) were needed to determine the minimum local anaesthetic volume (MLAV) of mepivacaine 2% using the Dixon up-and-down method to achieve a selective ultrasound-guided saphenous nerve block...

The aim of this study was to develop and evaluate a procedure for equine pudendal nerve block using a peripheral nerve locator. In the first experiment, six ponies were used to determine the relationship between elicited muscle contractions (anal, perineal or both) and nerves serving the perineal region (pudendal, caudorectal and perineal nerves) when methylene blue dye was injected using the electrolocation technique. This experiment showed that the pudendal nerve was approached effectively when both anal and perineal twitch were elicited during electrolocation...

BACKGROUND: The local anesthetic lidocaine can affect intra- and extra-cellular signaling pathways in both neuronal and non-neuronal cells, resulting in long-term modulation of biological functions, including cell growth and death. Indeed, lidocaine was shown to induce necrosis and apoptosis in vitro. While several studies have suggested that lidocaine-induced apoptosis is mitochondrial pathway-dependent, it remains unclear whether reactive oxygen species (ROS) are involved in this process and whether the observed cell death can be prevented by antioxidant treatment...

: Local anaesthetic injection between the tibial and commmon peroneal nerves within connective tissue sheath results in a predictable diffusion and allows for a reduction in the volume needed to achieve a consistent sciatic popliteal block. Using 3D ultrasound volumetric acquisition, we quantified the visible volume in contact with the nerve along a 5cm segment. METHODS: We included 20 consecutive patients scheduled for bunion surgery. Ultrasound guided popliteal block was performed using a posterior, out of plane approach at the level of división of the sciatic nerve...

INTRODUCTION AND OBJECTIVES: Quadratus Lumborum block was recently described and has already shown good results as an analgesic technique in abdominal surgeries, having the potential to significantly reduce opioids consumption and be a valid alternative to epidural catheter. We performed a type II Quadratus Lumborum block for analgesia in a septic patient having a sub-total gastrectomy. CASE REPORT: An 80 year-old, ASA III, male patient, weighting 50kg, with a history of arterial hypertension and hypercholesterolemia, diagnosed with sepsis due to purulent peritonitis was submitted to an open laparotomy...

OBJECTIVE: Local anesthetic-induced myotoxicity occurs consistently in animal models, yet is reported rarely in humans. Herein, we describe 3 sentinel cases of local anesthetic myotoxicity after continuous adductor canal block (ACB). CASE REPORT: Three patients underwent total knee arthroplasty that was managed with subarachnoid block plus ACB induced with 1.5% lidocaine or 1.5% mepivacaine bolus followed by 2% ropivacaine at 8 mL/h. Although initial postoperative recovery was normal, each patient on either postoperative day 1 or 2 developed progressive, profound weakness of the quadriceps muscles...

The effects of local anesthetics (LAs), including aminoamides and aminoesters, on the characteristics of single gramicidin A (GA) channels in 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC) bilayers were studied. Aminoamides, namely lidocaine (LDC), prilocaine (PLC), mepivacaine (MPV), and bupivacaine (BPV), reduced the conductance of GA channels. Aminoesters influenced the current fluctuations induced by GA differently; procaine (PC) did not affect the fluctuations, whereas tetracaine (TTC) distinctly reduced the conductance of single GA channels...

BACKGROUND: The aged are at increased risk of postoperative wound healing complications. Because local anesthetics are infiltrated commonly into the dermis of surgical wounds, we sought to determine whether local anesthetics adversely affect proliferative and biosynthetic functions of dermal fibroblasts. We also evaluated the effect of local anesthetics on insulin-like growth factor-1 (IGF-1) and transforming growth factor-β1 (TGF-β1), growth factors that are important regulators of wound healing...

BACKGROUND: A consequence of HIV infection is sensory neuropathy, a debilitating condition that degrades the quality of life of HIV patients. Furthermore, life-extending antiretroviral treatment may exacerbate HIV sensory neuropathy. Analgesics that relieve other neuropathic pains show little or no efficacy in ameliorating HIV sensory neuropathy. Thus, there is a need for analgesics for people with this particular pain. While lidocaine is used in the management of painful peripheral neuropathies, another local anesthetic mepivacaine, with a potentially improved bioavailability, could be utilized for the management of HIV neuropathic pain...
