L Sutton, D Edwards, M McColl
Pretibial lacerations are a common cause of presentation to accident and emergency departments. The management of these wounds is contentious with a variation in practise between individual institutions. We present the case of a 49-year-old female with a background of pulmonary atresia and associated pulmonary hypertension, who underwent successful outpatient negative pressure wound therapy (NPWT) for three pretibial lacerations. We would propose that this therapy is an effective option for the management of these wounds in independently mobile patients who are at high-risk when under anaesthetic...

OBJECTIVES: To investigate the impact of a dedicated cell salvage practitioner team on blood loss and allogeneic transfusion in abdominal aortic aneurysm (AAA) surgery. BACKGROUND: Cell salvage reduces allogeneic transfusion in AAA surgery, but is commonly performed by the anaesthetic nurse. At our hospital, a dedicated patient blood management practitioner is present for all elective open AAA repairs. METHODS/MATERIALS: Data were collected on 171 AAA patients operated on at the John Radcliffe Hospital, Oxford over a 3-year period, looking at the Patient Blood Management processes, including: blood loss, cell salvage, near-patient testing (thrombelastography) and transfusion rates of allogeneic blood products...

For the purpose of orientation, echolocating bats emit highly repetitive and spatially directed sonar calls. Echoes arising from call reflections are used to create an acoustic image of the environment. The inferior colliculus (IC) represents an important auditory stage for initial processing of echolocation signals. The present study addresses the following questions: (1) how does the temporal context of an echolocation sequence mimicking an approach flight of an animal affect neuronal processing of distance information to echo delays? (2) how does the IC process complex echolocation sequences containing echo information from multiple objects (multiobject sequence)? Here, we conducted neurophysiological recordings from the IC of ketamine-anaesthetized bats of the species Carollia perspicillata and compared the results from the IC with the ones from the auditory cortex (AC)...

Background and Aims: Awake fibre-optic intubation (AFOI) is an integral part of anaesthetic management of difficult airways. Conscious sedation is essential to assist AFOI. This study compared two different doses of dexmedetomidine in combination with topical spray and airway blocks for awake orotracheal fibre-optic intubation in patients undergoing elective cervical spine surgery with rigid cervical collar in situ. Methods: A randomized, prospective, comparative study design was conducted in sixty patients divided into two groups: Group (L) (n = 30) patients received low dose of dexmedetomidine (0...

REVIEW
M Mosing, J M Senior
In the first edition of this journal Barbara Weaver wrote a review titled 'Equine Anaesthesia' [1], stating, that, at that time it was quickly becoming accepted practice that many horses were being anaesthetised "by essentially similar procedures, i.e. premedication, induction and then maintenance by controlled inhalation". Her review focussed upon the last procedure. Maintenance of anaesthesia through controlled inhalation implies that an anaesthetic agent can be suitably delivered via the respiratory system and that ventilation is sufficiently maintained to deliver that agent and maintain adequate gas exchange...

Melnick-Needles syndrome (M-NS) is a rare genetic disorder which primarily affects skeletal developments. M-NS may also affect the cardiorespiratory and renal systems. A 35 kg patient presented complaining of abdominal pain. Following a positive pregnancy test and ultrasound examination, she was diagnosed with a ruptured ectopic pregnancy. She had a significant background history of M-NS, obstructive sleep apnoea (with narrow gauge tracheostomy in situ), obstructive lung disease and scoliosis. She received fluid resuscitation, and the case was managed using an open salpingectomy and clot evacuation under combined spinal/epidural anaesthesia...

BACKGROUND: Inspiratory resistive breathing (IRB), a hallmark of obstructive airway diseases, is associated with large negative intrathoracic pressures, due to strenuous contractions of the inspiratory muscles. IRB is shown to induce lung injury in previously healthy animals. Src is a multifunctional kinase that is activated in the lung by mechanical stress. ERK1/2 kinase is a downstream target of Src. We hypothesized that Src is activated in the lung during IRB, mediates ERK1/2 activation and IRB-induced lung injury...

Background and Aims: Anaesthesia for medical purposes was introduced in the 19th century. However, the physiological mode of anaesthetic drug actions on the nervous system remains unclear. One of the remaining questions is how these different compounds, with no structural similarities and even chemically inert elements such as the noble gas xenon, act as anaesthetic agents inducing loss of consciousness. The main goal here was to determine if anaesthetics affect the same or similar processes in plants as in animals and humans...

Songbirds are a well-established animal model to study the neural basis of learning, perception and production of complex vocalizations. In this system, telencephalic neurons in HVC present a state-dependent, highly selective response to auditory presentations of the bird's own song (BOS). This property provides an opportunity to study the neural code behind a complex motor behavior. In this work, we explore whether changes in the temporal structure of the sound envelope can drive changes in the neural responses of highly selective HVC units...

BACKGROUND: Pain of lumbar facet-joint origin is a common cause of low back pain in adults and may lead to chronic pain and disability, with associated health and socioeconomic implications. The socioeconomic burden includes an inability to return to work resulting in loss of productivity in addition to direct and indirect health-care utilisation costs. Lumbar facet-joints are paired synovial joints between the superior and inferior articular processes of consecutive lumbar vertebrae and between the fifth lumbar vertebra and the sacrum...

Nadeena Sri Swarnagupta Jayasuriya, Indika Danuka Weerapperuma, Malagoda Gamage Chathura Kanchana Amarasinghe
The palatal injection of anaesthesia is more painful for the patient when compared to other sites of the oral cavity. Pre-cooling (cyro anaesthesia) is a well-known method practiced to reduce pain, with the use of ice or refrigerant spray on the affected site. The already known methods of ice application to the palatal site have few practical drawbacks. Therefore, this technical note highlights the use of an iced cotton bud as a novel way of providing effective pre-cooling for palatal anaesthesia. Commercially available cotton buds were dipped in clean water and then placed in the freezer...

Background: One important task of the emergency anaesthesia service is to provide rapid, safe and effective anaesthesia for emergency caesarean sections (ECS). A Decision to Delivery Interval (DDI) <30 minutes for ECS is a quality indicator for this service. The aim of this study was to assess the DDI and the impact of chosen anaesthetic technique (general anaesthesia (GA), spinal anaesthesia (SPA) with opioid supplementation, or "top-up" of labour epidural analgesia (tEDA) with local anaesthesia and fentanyl mixture) and work shift for ECS at Danderyds Hospital, Sweden...
