The degradation of succinylcholine is accomplished by the human serum based enzyme pseudocholinesterase. Availability of pseudocholinesterase within the human being can be deficient as a result of an inherited or acquired cause. This case report will describe a female patient who was diagnosed with an acquired pseudocholinesterase deficiency.

The authors are to be commended both for an excellent clinical outcome and for bringing forward this important topic. In the most recent triennial report in to maternal mortality in the UK intracerebral haemorrhage is the most common cause of maternal death in cases of eclampsia/pre-eclampsia, and we must therefore assume that from time to time we may be called upon to assist in the management of this complex combination of clinical challenges. Such patients present several dilemmas to the anaesthetist: How can a rapid sequence induction be achieved whilst bl...

The syndrome is a melange of respiratory, haematological, neurological and cutaneous symptoms and signs associated with trauma and other disparate surgical and medical conditions. The pathogenesis is still debated. It is clear that fat emboli are quite common yet the clinical syndrome is rare. Diagnosis is by pattern recognition as befits a syndrome, but the recently defined features on MRI could now be used to increase the probability of the diagnosis. Various therapeutic options have been tried and failed. At present steroids have a single meta-analysis suggesting benefit but it is in the t...

Firstly, the extreme physiological features of neonatal lungs make them very difficult to ventilate with an anaesthesia ventilator. Gattinoni’s “baby lung” concept to describe ARDS lungs in adults comes from the physiological features of neonatal lungs (low dynamic compliance, low pulmonary time constant, low FRC, high closing volume, proneness to atelectasis, high inspiratory airway resistance). Secondly, the performance and technology (peak flow, insufflation power, trigger sensitivity, ventilation modes, etc.) of anaesthesia ventilators is still less advanced than those of critical care ventilators. It is possible to ventilate a normal healthy adu...

Historically, Volume-controlled ventilation (VCV) has been the universal ventilatory mode used by the anesthesiologists in operating theatre. Nevertheless, since Pressure-controlled ventilation (PCV) was proposed as an alternative to VCV in ICU patients with ALI/ARDS, there has been renewed interest in ventilatory pressure modes in anesthesia. At present the anesthesia workstations usually have available some different modes such as PCV or pressure support ventilation (PSV). The purpose of this review is to evaluate whether ventilatory pressure modes, such as the PCV offer some benefit over the clas...

Its pathogenesis is related to pulmonary inflammation, but this appears to be secondary to multiple etiological factors, including the surgical procedure itself, extra corporeal circulation (ECC), ischemia-reperfusion injury, and mechanical ventilation (MV). On the other hand, the presence of atelectasis remains one of the principal causes of PPD. The open lung approach (OLA) is a protective ventilation strategy, typically initiated after orotracheal intubation and maintained until extubation of the patient. Compared to a conventional ventilation strategy, OLA improves gas exchange parameters, induces a minor elevation of inflammatory mediators, and retains more residual functional capacity...

The performance characteristics of these machines are related to the physical structure of the breathing circuit. Limitations related to the classical circle breathing circuit are progressively disappearing with the arrival on the market of modern anesthesia machines with modified circular circuits, which offer a series of advantages in relation to the classic circular circuit. The present review describes the basic functional characteristics common to any anesthesia machine and that determine their clinical performance. The knowledge of these characteristics is essential for the clinical use o...

Mechanisms of central tolerance involve deletion of self-reactive T cells. Mechanisms of peripheral tolerance are reviewed and also the identification of a subset of regulatory T cells which are characterised by the expression of the transcription factor FoxP3.Interesting recent insights on the role of the ‘anti-inflammatory’ cytokine transforming growth factor β which can ultimately lead to the generation of inhibitory Tregs or inflammatory Th17 cells (CD4 helper T cells which secrete the pro-inflammatory cytokine IL17) are discussed.There are many ways to induce experimental tolerance in animals, however these are difficult to translate tolerance into the clinical context.

Non Heart Beating Donors (NHBD) or Donors after Cardiac Death (DCD) produce organs that have experienced warm ischaemia, which compromises their early function. Extracorporeal membrane oxygenation offers the possibility of minimizing this inevitable damage and extending the range of organs that can be harvested.

In clinical transplantation, the main concern is the continuing rise in the number of patients on transplant waiting lists and the widening imbalance between demand and supply of organs from suitable donors. In renal transplantation, the majority of kidneys available are recovered from heart beating donors (HBDs). In recent years, shortage of kidneys from these donors has led to using organs from non-heart-beating donors (NHBDs) to expand the donor pool. However, these organs are often exposed to periods of both warm and cold ischaemic damage which determine short-term and long-term functional and survival outcomes of allografts. Therefore, minimising organ responsivene...

However, organ transplant preservation and rejection remain major issues in surgical medicine. The success of the transplant is dependent on the quality/healthiness of the organ or tissue, and the use of improved ways to minimise rejection. Transplant rejection refers to the body recognising the transplant as foreign and initiates attack upon the transplanted organ or tissue. The body is designed to recognise infection organisms including bacteria and viruses and will recognise the transplant in the same way. In order to minimise this possibility, serotyping is undertaken to determine the most appropriate donor-recipient match and through the use of immunosuppressant drugs.

The new one is the 40th edition and the 150 year anniversary edition. I have a well used old copy of Grays anatomy which was, curiously, also an Anniversary edition. It is a large book with very small print and crowded diagrams printed on fine but expensive paper. Looking something up was always hard even when ones eyesight was good but now requires a bright light and reading glasses. There was always a sense of achievement in finding the answer to a question. It is the gold standard though there are a host of easier to read books around. Well anatomy does not change so when I was asked to review the latest edition I expected much the same.

Their prompt investigation of this bleeding revealed HELLP syndrome, but this diagnosis could have been significantly delayed because of the absence of hypertension and significant proteinuria. Although described as atypical, this case is typical in the subtlety of presenting signs and symptoms followed by rapid development of multisystem problems including post partum haemorrhage, disseminated intravascular coagulation (DIC), pulmonary oedema, and renal dysfunction.

However, the anaesthetist role extends far beyond providing general anaesthesia. They can provide sedation if required, have the ability to perform different regional blocks, and to treat both acute and chronic orbital pain conditions. Of as great importance is that anaesthetists routinely monitor patients under a wide range of anaesthetics and are able to identify and manage serious life threatening complications if they happen perioperatively.

Ocular injuries are commonly encountered in clinical practice as an estimated 750,000 patients are hospitalized with eye injuries annually throughout the world. Many, particularly those with open globe injuries, require surgery, often under emergency conditions that make the patient’s anesthetic management challenging. This paper reviews epidemiological data illustrating the prevalence and incidence of serious eye injuries and then presents a case study detailing the anesthetic management of a severely traumatized patient to illustrate a discussion of current options and recommendations for the management of such cases.

Dacryocystorhinostomy (DCR) is the procedure designed to treat primary or secondary adult anatomical obstruction. External DCR is the traditional surgical approach, however endoscopic DCR can be done. In the past, general anaesthesia (GA) has been considered as the gold standard for DCR surgery; endotracheal intubation and throat pack offer an important function as protective mechanisms of the patient’s airway against blood aspiration. Head up position, hypotensive anaesthesia, incision infiltration with lidocaine/epinephrine together with insertion of nasal pack soaked in decongestant solution are a routine measures to guard against intraoperative bleeding that may hinder surgical site...

Thorough preoperative assessment is essential especially for those scheduled for general anaesthesia.Patients on anticoagulants and antiplatelet drugs scheduled for V-R surgery should continue their routine medication. However, where there are specific concerns, the anaesthetist, surgeon and patient should discuss the risks and benefits of continuing their routine medication to agree an acceptable approach.Local anaesthetic techniques are now far more commonly used than general anaesthesia for V-R surgery. Clinicians must recognize the limitations and contraindications of both approaches.Whenever local anaesthetic techniques are used, attention to small details can make a h...

Most glaucoma surgery is done on the anterior part of the globe, and can be performed using any of the standard anaesthesia techniques. However, many surgeons prefer to avoid putting any LA near to the optic nerve, and simply anaesthetise the surgical area. Options include sub-conjunctival, sub-Tenon’s, or topical anaesthesia.Glaucoma patients may, of course, have surgery for other reasons. The anaesthesiologist needs to be familiar with the systemic side-effects and interactions of glaucoma medications.Acute rise in intra-ocular pressure may occur in predisposed eyes, and this can be sight-threatening. Acute angle closure glaucoma is discussed, alo...

There is a broad introduction to each chapter, which encompasses the pathophysiology and management of each disease process followed by a more in-depth look at the anaesthetic implications. The editors have made what I imagine is a difficult decision to allocate space to commonly occurring disease processes and also to the more esoteric.

Enhanced Recovery (ER) programs raise the exciting prospect of reduced resource utilisation in combination with improved (or at least equivalent) outcomes. Careful monitoring of process (compliance with ER elements) and outcome are essential if this goal is to be achieved without unintended harm to patients (e.g. increased readmission due to postoperative morbidity arising in the community).Risk (case-mix) adjustment is necessary to separate the influence of patient and care factors and thereby minimise the effects of case-mix variation on evaluation of care quality.

Typically, the anaesthetist administers boluses of approximately 200–250 ml of colloid solution whilst measuring changes in stroke volume or another measure of fluid responsiveness, such as stroke volume variation. When the stroke volume measurements indicate that the cardiovascular system is no longer fluid responsive, the patient is assumed to be close to the upper flat phase of the Frank–Starling Curve. Research using TFA suggests that post-operative complications such as ileus and length of hospital stay are reduced when fluid therapy is managed in this way. Most of the positive evidence for TFA has been achieved using the oe...

Why devote an entire issue of an anaesthetic journal to surgical pathways? The various Doppler fluid optimisation trials and the recently completed National Technology Adoption Centre project on the practical effect of implementing Oesophageal Doppler monitoring demonstrate that intraoperative anaesthetic management can have a direct bearing on postoperative outcomes such as length of stay. Hence as anaesthetists we should be judged not just on traditional ‘anaesthetic’ outcomes of postoperative pain and nausea, but on the basis of our shared responsibility for ‘surgical’ outcomes such as complications and length of stay. However anaesthetists have an important role to play at all stages in the p...

Antiplatelet agents (APA) have proven efficacy in the primary and secondary prevention of ischaemic heart and cerebrovascular disease.

The impetus to use numerical values of haemoglobin concentration as transfusion triggers has been driven by several factors that have been clearly outlined by the authors. Whilst public perception may differ, blood itself has never been safer and currently the most pressing problem associated with this pharmacological product is the reduction in the donor pool and the exponential rise in cost due to even more sensitive screening tools and pathogen inactivation methods. This has to be tempered with the fact that decisions at the bedside will depend ultimately on the rapidity of blood loss that leads to anaemia and the co morbidities of the patient that m...

There is very little evidence to suggest a restrictive policy is harmful although higher levels might be sensible in those with cardiovascular disease. A considerable tranche of literature shows that blood is bad for a patient but to date no clear mechanism has emerged and there is an argument that needing blood, a surrogate for illness may be as relevant. The impact of anaemia in the postoperative phase has not been evaluated adequately. The triggers lend themselves to non-acute elective situations but where there is acute blood loss and haemodynamic instability a slightly higher threshold, nearer 10g/dl, allows a margin of safety.

Haemodialysis treatment in the immediate period prior to transplantation is associated with a poorer outcome including a higher rate of delayed graft function (DGF). Individuals undergoing renal transplantation require close intra-operative monitoring with optimisation of intravascular fluid volume to maximise renal transplant perfusion. Whether mannitol, loop diuretics, dopamine or other therapies influence the rate of DGF is not possible to decide. For renal transplant recipients admitted immediately post-procedure to intensive care unit (ICU) the prognosis is good. This is in contrast to those admitted usual...

Whilst it can be treated by the use of renal replacement therapies an independent increase in mortality still exists. It is therefore seems intuitive that the prevention of AKI should be associated with a reduction in both mortality and morbidity and an improvement in patient care for this reason there has been many attempts to develop strategies to reduce the incidence of AKI. These strategies involve the use of therapeutic agents to prevent renal failure, the avoidance of nephrotoxic agents and the maintenance of normal hydration and renal perfusion. More recently there has been focus on the early recognition of patients at risk of developing AKI...

More recently it has been demonstrated that even relatively small increments of serum creatinine portend a worse outcome. This has prompted the development of new definitions based on small rises in serum creatinine or decreases in urine output. Acute kidney injury on the intensive care unit (ICU) is usually multifactorial secondary to hypovolaemia and sepsis resulting in hypoperfusion of the kidneys. In patients with good baseline kidney function the condition is generally reversible if the patient regains health. However it has been recognised that kidney function does not always completely recover. An episode of AKI may represent an antecedent to the development of chronic kidney di...

The term AKI encompasses all types of acute renal failure (ARF). The National Service Framework (NSF) for Renal Services has recommended that patients at risk of suffering from AKI should be identified promptly, with hospital services delivering high-quality, clinically appropriate care in partnership with specialised teams.

The book opens with a beautifully concise and excellently illustrated synopsis of the structure and function of the brain and spinal cord, and continues with a clear and logical progression of short chapters through sections on neurophysiology and pharmacology before entering the clinical arena. The format makes it easy to find specific topics of interest. Each chapter ends with a useful list of key points and recommended further reading, and although the authors are drawn from America, Canada, Australia and the UK there is surprisingly little overlap of content, and a uniformity of style for which I congratulate the editors.

Integral to these functions, and consequently, AMPA receptor activity is a class of proteins termed transmembrane AMPA receptor regulatory proteins (TARPs) which also possess diverse effects on AMPA receptor pharmacology.

Characteristics of schizophrenia can be divided into positive, negative and cognitive symptoms. Contributory factors of the disorder include genetics, early environmental factors and neuropsychological factors. Many years of research has investigated the dopamine hypothesis and glutamate hypothesis of schizophrenia, but more recently the field is scrutinizing the combined interactions of the glutamatergic and dopaminergic systems.

Here I review the current understanding of Amyotrophic Lateral Sclerosis (ALS), the most common form of MND, looking particularly at the causative factors, and the available treatments for the disease. Familial ALS can be caused by a mutation in SOD1; research into the effects of this mutation has given an insight into the mechanisms by which MND progresses. Mutant SOD1 causes the initiation and progression of MND via protein aggregation, disrupted axonal transport, and oxidative stress within motor neurons. There is currently only one drug available for the treatment of motor neuron disease; Riluzole. I exami...

To date, glutamate modulator riluzole is the only drug that has proved effective against disease progression. Based on this evidence, it has been proposed that glutamate excitotoxicity contributes to the neurodegeneration observed in ALS, with α-amino-3-hydroxyl-5-methyl-4-isoxazole-propionate receptors (AMPARs) emerging as a likely candidate for glutamate receptor-mediated excitotoxicity. The calcium (Ca2+) conductance of AMPARs is determined by the presence of the edited GluR2 subunit, which renders the AMPAR Ca2+ impermeable. Of particular significance, reduced GluR2 editing at the Q/R site of AMPARs has been reported in spinal moto...

However, drug treatment for neuropathic pain remains inadequate, with the best available treatments having limited efficacy and dose-limiting side effects. Cannabinoids have been shown in clinical trials to be moderately effective at reducing neuropathic pain, but doses of cannabinoids currently in use are severely curtailed by psychoactive side effects through actions on the cannabinoid CB1 receptor. A relatively new class of drugs, selective cannabinoid CB2 receptor agonists, have shown considerable efficacy in a variety of animal models of neuropathic pain. Importantly, these drugs lack the psychoactivity of non-selective cannabinoid receptor agonists. The mechanisms by whic...

The causative organisms are often different to those causing disease in the community, or even for the rest of the hospital. Therefore management of the infected ICU patient is complicated and requires careful consideration. In addition, the emergence of multi-drug resistant organisms further complicates treating such patients as they tend to be more susceptible to infections with less physiological reserve and therapeutic options are frequently reduced.

As advances in stent development and manufacture are made, there are more patients being treated with airway stents. Stenting can be short term or long term and can be used for the management of large airway obstruction where surgery carries both morbidity and mortality.Pre-operative assessment is particularly important and may determine which of the wide range of techniques that have been used is most appropriate for the individual case.The anaesthetic management of patients with stents already in situ is becoming more important as the number of patients with stents increases.

The number of microglia is thought to make up 5–20% of the entire glial cell population. Origin of microglia has been discussed for several decades. Recently, microglia are widely considered to originate from mesodermal monocyte/macrophage cell lineage, because of similarities in cell surface molecular phenotype. In normal adult brain, microglia have finely branched and ramified cell processes that extend in all directions, and survey the brain microenvironment. When the brain is injured by trauma, stroke and other neurodegenerative disorders, microglia transform their morphology into an activated phenotype, and accumulate in the affected sites. Activation of microglia has been believed to lead to neuroto...

An organized trauma system from the site of accident to the Intensive Care Unit is the cornerstone of treatment of TBI patients. Treatment in the emergency room must focus on swift normalization of blood pressure and oxygenation. During tracheal intubation cervical spine protection and the risk of aspiration, must be balanced against the risk of hypotension and hypercapnia. Both hyper- and hypoventilation can be deleterious in TBI patients, and consequently, they should be normoventilated as guided by end-tidal CO2.

A clinical approach with focus on cardiovascular diagnostics and rational goal-directed therapy is likely to reduce the high mortality. The treatment involves focus control, broad-spectrum antibiotics, target-oriented fluid therapy and vasopressor and inotropic agents guided by frequent reassessments of the patients' response to intervention.

We go through some of the vast amount of evidence supporting the use of real-time ultrasonography and describe its use and common pitfalls. Ultrasound equipment is readily available in almost every hospital but is often not used. Our hope is that this article can give physicians and nurses some means to increase their success rates and decrease the amount of time they spend on gaining intravenous access. Hopefully patient satisfaction will increase at the same time.

In order to ensure the optimal treatment and uniform implementation worldwide, guidelines are published every fifth year. A considerable amount of research is done, and although there have been advances, there is always room for improvement. Prospective studies of cardiac arrest in humans are extremely difficult to conduct, especially randomised studies, and the number of patients involved in the studies is sparse. This paper provides updated available information on cardiac arrest, as well as a discussion of recommendations, based on the guidelines published in November 2005 by the International Liaison Committee on Resuscitation.

Time is the limiting factor and any delay in treatment must be carefully balanced against the risk of further deterioration in patient condition. The patient history is commonly incomplete and previous medical records may not be available. Anaesthesiologists are key players in the team taking care of emergency patients because we have the skills to assess and support vital functions no matter if the patient is undergoing surgery or not. The initial evaluation of any emergency patient is based on the traditional algorithm looking at airway, breathing, and circulation in that order. An accurate diagnosis may not be attainable but the most important aspect during the first few minutes is to ensure that life threatening conditions are ...

Those antibodies may have developed during pregnancy or following blood transfusion. They react with specific ‘cognate’ antigens in the recipient and in some patients, but not all, this results in an acute lung injury pattern. The problem resides in the plasma, so the incidence with FFP is far higher than with red cells.Blood transfusion services have adopted several ways of reducing risk such as using untransfused male donors. Leucodepletion may also have a benefit.Diagnosis is an issue as it is easily confused with transfusion associated circulatory overload TACO and often the right preconditions exist for both.

The full Act came into force on 1st October 2007. The Act sets down decision specific criteria for the assessment of capacity, and “best interests” principles to enhance decision making for patients without capacity. Patients undergoing serious treatment must have an Independent Mental Capacity Advocate appointed if there is no one appropriate to consult in determining the patient's interests. A person may be appointed as personal attorney under a Lasting Power of Attorney to make decisions on the patient's behalf. Advance Decisions about the refusal of life-sustaining treatment are regulated statutorily for the first time. T...

The stimulating nerve catheter is a very useful addition to the armamentarium of the regional anaesthesia practitioner. The stimulating nerve catheter makes it possible to verify the perineural location before delivering targeted continuous infusion of local anaesthetic for extended pain relief. The increasing use of ultrasound in echolocation of neural structures has added a new dimension to the popularity of peripheral nerve blocks.

In recent years, the popularity of ultrasound-guided nerve blocks has significantly increased out of the recognition of its higher efficacy and safety. Its importance is further enhanced in paediatrics and especially in neonates as there are restrictions in the volume and maximum dosage of local anaesthetic that can be used. Ultrasound has allowed the usage of significantly smaller doses and concentrations by direct deposition of the drug around the nerve. It also allows the dynamic visualisation of the advancement of the block needle, adjacent anatomical structures and allows dynamic vision of local anaesthetic spread. (Source: Current Anaesthe...

Nerve stimulation using anatomical landmarks has been conventional method of nerve localisation. With the advance in technology, the use of ultrasound in regional anaesthesia has been steadily increasing. In addition to localisation of nerves and other structures under direct visualisation, ultrasound has the potential to reduce complications and minimise the local anaesthetic toxicity by injecting right dose at the right site. The principles, advantages, disadvantages and applications of ultrasound have been reviewed in this article.

It is also used in intravenous regional blocks both for upper and lower limbs. Complications can be either local to the affected limb or systemic. Systemic effects can occur during inflation and deflation of the tourniquet. General guidelines should be followed in order to minimize such complications.
