Source: Journal of Orthopaedics, Trauma and Rehabilitation; Jun 2017; vol. 22 ; p. 41-47 Publication Date: Jun 2017 Publication Type(s): Journal: Article Abstract:Background Anaesthetic technique can influence mortality and morbidity following hip fracture surgery. However, its influence on postoperative mobilisation is not clear. In this study, we evaluated the influence of anaesthetic technique on postoperative mobilisation. Methods In this prospective observational study, we included all consecutive patients who underwent surgery for hip fracture between 1 January 2012 and 31 December 2013 at our institution. Any patients who died prior to mobilisation or who could not be followed up after surgery were excluded. Data was collected on demographics, clinical characteristics, anaesthesia technique and surgical factors, and date and time of admission, operation, first mobilisation and discharge. Results Of the 1040 patients included in the analysis, 264 received general anaesthesia only (Group GA), 322 received general anaesthesia with regional anaesthesia (Group GARA), and 454 received central neuraxial blockade anaesthesia with or without sedation (Group CNB). There was no significant difference in age (p = 0.56), sex (p = 0.23), number of comorbidities (p = 0.06), residential status (p = 0.18), time to surgery (p = 0.10) and length of hospital stay (p = 0.30) between the three groups. There was a statistically significant difference in ASA grade (p = 0.01), implant type used (p = 0.04), grade of operating surgeon (p = 0.02) and grade of anaesthetist during surgery (p = 0.004) among the three groups. Patients in Group GARA had a median time-to-first mobilisation of 23.8 hours after surgery, compared to 24.1 hours in Group GA and 24.3 hours in Group CNB. This difference was not statistically significant after controlling for confounding factors (p = 0.45). Conclusion Our results show that anaesthetic technique does not influence time-to-first mobilisation after hip fracture surgery.

We hypothesised that network analysis, in addition to the traditional differential gene expression and ontology analysis, would enable identification of the effects of anaesthesia on interactions between genes. Rats (n=10 per group) were randomised to anaesthesia with isoflurane in oxygen or oxygen only for 15min, and 6h later brains were removed. Differential gene expression and gene ontology analysis of microarray data was performed. Standard clustering techniques and principal component analysis with Bayesian rules were used along with social network analysis methods, to quantitatively model and describe the gene networks. Anaesthesia had marked effects on genes in the brain with differential regulation of 416 probe sets by at least 2 fold. Gene ontology analysis showed 23 genes were functionally related to the anaesthesia and of these, 12 were involved with neurotransmitter release, transport and secretion. Gene network analysis revealed much greater connectivity in genes from brains from anaesthetised rats compared to controls. Other importance measures were also altered after anaesthesia; median [range] closeness centrality (shortest path) was lower in anaesthetized animals (0.07 [0-0.30]) than controls (0.39 [0.30-0.53], p<0.0001) and betweenness centrality was higher (53.85 [32.5670.00]% compared to 5.93 [0-30.65]%, p<0.0001). Simply studying the actions of individual components does not fully describe dynamic and complex systems. Network analysis allows insight into the interactions between genes after anaesthesia and suggests future targets for investigation. Copyright © 2016 Elsevier B.V. All rights reserved.

It should be carried out as soon as safely possible, and performed to the same standards as in-hospital emergency anaesthesia. It should only be conducted within organisations with comprehensive clinical governance arrangements. Techniques should be straightforward, reproducible, as simple as possible and supported by the use of checklists. Monitoring and equipment should meet in-hospital anaesthesia standards. Practitioners need to be competent in the provision of in-hospital emergency anaesthesia and have supervised pre-hospital experience before carrying out pre-hospital emergency anaesthesia. Training programmes allowing the safe delivery of pre-hospital emergency anaesthesia by non-physicians do not currently exist in the UK. Where pre-hospital emergency anaesthesia 21 skills are not available, oxygenation and ventilation should be maintained with the use of second-generation supraglottic airways in patients without airway reflexes, or basic airway manoeuvres and basic airway adjuncts in patients with intact airway reflexes. © 2017 The Authors.

Author(s): DeCou, J; Johnson, K Source: Anaesthesia; Jan 2017; vol. 72 Publication Date: Jan 2017 Publication Type(s): Journal Article Review Abstract:A significant amount of anaesthetists' work involves the prediction of drug effects and interactions to produce a smooth general anaesthetic that minimises drug side effects and promotes rapid emergence. Successfully managing this process requires a basic understanding of drug effects, experience and inevitably some guesswork, since it is difficult (and in some cases impossible) to anticipate all relevant patient and surgical factors. Although data are generally available to allow calculation of plasma drug and effect site concentrations, this is often difficult to apply in complex clinical contexts, particularly when multiple drug types are used. In recent years, manufacturers have developed and incorporated into anaesthetic workstations technologies that use drug pharmacodynamic and pharmacokinetic data to predict drug effects and interactions. Such systems can predict the duration and effects of drugs during anaesthesia and assist the anaesthetist to understand complex drug interactions. With this information available, different drug types, doses and combinations may be tailored in a scientific way to maximise useful effects whilst 22 minimising overdose and side-effects, particularly in high-risk patients. Examples are used to illustrate how such systems can be used in practice, and how drug effects and interactions can be simulated to "rehearse" an anaesthetic before any drugs are actually administered. At present only a small number of anaesthetic workstations use this technology, and as yet they are not able to manage all drugs used in anaesthetic practice. However, such systems have the potential to help anaesthetists manage the complexity of their work, and to provide information on predicted drug effects in a way that is useful and relevant to both experienced anaesthetists and trainees. © 2017 The Association of Anaesthetists of Great Britain and Ireland.

We compared the performance of the APL valves of the GE Aisys CS2 and the Draeger Fabius anaesthetic machines during closure and opening from 1-20 and from 20-1 cmH2 O, using standardised experimental baby and adolescent patient lung models. Airway pressures and inspiratory tidal volumes were measured using an ASL-5000 test lung and a GE Aisys CS2 near-patient spirometry sensors. In both lung models, the GE Aisys CS2 APL valves demonstrated non-linear behaviours for airway pressures and for inspiratory tidal volumes, with a sharp increase at set APL pressure levels of 8-10 cmH2 O. With further closure of the GE Aisys CS2 APL valves up to 20 cmH2 O, inspiratory tidal volumes decreased to ~50% of the highest values measured. Airway pressures in the Draeger Fabius APL valves demonstrated a near linear increase and decrease. Airway pressure values measured in the Draeger Fabius were never higher than those set by the APL valves, whereas in the GE Aisys CS2 , they considerably exceeded set pressures (by up to 27 cmH2 O). We conclude that the performance of the GE Aisys CS2 APL valve does not allow safe bag-assisted ventilation of a patient's lungs. © 2016 The Association of Anaesthetists of Great Britain and Ireland.

This article analyses the efficacy and safety of desflurane for diagnostic-therapeutic procedures in remote areas far from operating room in a group of selected patients with no known associated respiratory disease. A retrospective analysis was performed on 2,072 general anaesthesia procedures stored in a computer database, in which desflurane was used in a Paediatric Pain Unit during the years 2013 and 2014. An analysis was also performed using the patient demographics, type of procedure, anaesthetic technique, type of airway management, patient cooperation, and incidence of anaesthetic complications. The study included 876 patients, with a mean age of 8.8 years. The main procedures were bone marrow aspirates (23%), lumbar punctures (20%), panendoscopies (15%), and colonoscopies (5%). Induction was intravenous with propofol (26%) or inhalation with sevoflurane in the remaining 74%. Maintenance consisted of remifentanil and desflurane at mean end tidal concentrations of 6.2±2.1%. The airway was managed through a nasal cannula or face mask in spontaneous ventilation. The effectiveness was 98%, and the incidence of side effects was 15%, which included agitation (6%), headache (4%), nauseavomiting (3%), and laryngospasm (2%). The maintenance with desflurane (at concentrations close to the hypnotic-MAC in spontaneous ventilation) was effective, with a rapid recovery, and with a low incidence of adverse effects.

Release of anaesthetic is achieved by stirring of the formulation, allowing controlled and 24 responsive release of anaesthetic at a variety of fixed flow rates between 0.5 l.min-1 and 5 l.min-1 , with ventilated, non-ventilated and draw-over breathing systems. Anaesthetic release was evaluated using target anaesthetic concentrations ranging from 0.5% v/v to 8% v/v to mimic those typically required for induction and maintenance of anaesthesia, and lower concentrations suitable for sedation. Under all conditions, output could be maintained within 0.1% v/v of the intended setting, and the device could deliver a controlled level of anaesthetic for at least 60 min, with compensation for different ambient temperatures (10-30 °C) and carrier gas flow rates. This device offers a simple, inexpensive method of delivering safe concentrations of volatile anaesthetics for a wide range of applications. © 2016 The Association of Anaesthetists of Great Britain and Ireland.

Many different protocols of local anaesthesia during endometrial ablation are used and described. However, prospective studies to assess and evaluate these protocols appear to be scarce. To evaluate systematically the different local anaesthesia techniques in relation to pain perception during endometrial ablation. Medline and Embase were systematically searched and reference lists of selected articles were checked for missed publications. All types of studies reporting the performance of endometrial ablation under local anaesthesia in ten or more women were included. Data about the procedure, the protocol of local anaesthesia, the acceptability and side-effects were extracted. Twenty-five studies, involving 2013 women, were included. Applied anaesthesia techniques included intracervical, paracervical and intrauterine anaesthesia or a combination of these techniques. Women who received a combination of either intra- or paracervical anaesthesia and intrauterine injections reported significantly lower pain scores than those who received no local anaesthesia or intra- or paracervical anaesthesia alone (P = 0.000), but the quality of evidence is low. The acceptability of endometrial ablation under local anaesthesia was 25 high (77-94%). Endometrial ablation under local anaesthesia is a safe, feasible and acceptable procedure. The combination of either intra- or paracervical anaesthesia with intrauterine injections seems to be promising, but has to be investigated more thoroughly.

Database: Medline Training responsibly to improve global surgical and anaesthesia capacity through institutional health partnerships: a case study. Author(s): Macpherson, Laura; Collins, Maggie Source: Tropical doctor; Jan 2017; vol. 47 (no. 1); p. 73-77 Publication Date: Jan 2017 Publication Type(s): Journal Article Review Abstract:Urgent investment in human resources for surgical and anaesthesia care is needed globally. Responsible training and education is required to ensure healthcare providers are confident and skilled in the delivery of this care in both the rural and the urban setting. The Tropical Health and Education Trust (THET), a UK-based specialist global health organisation, is working with health training institutions, health professionals, Ministries of Health and Health Partnerships or 'links' between healthcare institutions in the UK and low- or middleincome country (LMIC) counterparts. These institutions may be hospitals, professional associations or universities whose primary focus is delivery of health services or the training and education of health workers. Since 2011, THET has been delivering the Health Partnership Scheme (HPS), a UK government-funded programme that provides grants and guidance to health partnerships and promotes the voluntary engagement of UK health professionals overseas. To date, the £30 million Scheme has supported peer-to-peer collaborations involving more than 200 UK and overseas hospitals, universities and professional associations across 25 countries in Africa, Asia and the Middle East. In this paper, we focus on four partnerships that are undertaking training initiatives focused on building capacity for surgery and anaesthesia. In order to do so, we discuss their role as a responsible and effective approach to harnessing the expertise available in the UK in order to increase surgical and anaesthesia capacity in LMICs. Specifically, how well they: (1) respond to locally identified needs; (2) are appropriate to the local context and are of high quality; and (3) have an overarching goal of making a sustainable contribution to the development of the health workforce through education and training. The HPS has now supported 24 training initiatives focused on building capacity for surgery and anaesthesia in 16 countries across sub-Saharan Africa, Asia and the Middle East. THET argues that these initiatives are both responsible and effective. The four partnerships featured in this paper have demonstrated not only their effectiveness in increasing health worker skills and knowledge, but have done so across a variety of surgical and anaesthesia disciplines and within different contexts. This wide reach and applicability of partnership initiatives adds even greater value to their use as responsible training interventions. One challenge that has faced these partnerships has been the capture of improvements to patient outcomes as a result of improved practice. To counteract the problems of data collection, partnerships are collecting anecdotal evidence of improvements at the patient outcome level. The interventions supported by THET have been able to demonstrate success in improving health worker skills and knowledge, and albeit to a lesser extent, in improving patient outcomes. The implementing partners are achieving these successes by training responsibly: 26 responding to locally identified need, implementing projects that are appropriate to the local context and are of high quality, and establishing mechanisms that ensure selfsufficiency of the health worker training and education that is delivered. Greater investment in responsible training initiatives such as these are required to address the significant lack of access to appropriate and safe surgical and anaesthesia interventions when needed and the growing burden of disease. © The Author(s) 2016.

After institutional ethics committee approval, a link to an online questionnaire was sent by e-mail to anaesthesiologists in Argentina, Bolivia, Chile, Colombia, Panamá, Paraguay, Perú, and Uruguay. The questionnaire was processed anonymously. A total of 1,260 completed questionnaires were received. The results showed that 97.6% of the anaesthesiologists that responded used regional anaesthesia in clinical practice, 66.9% performed peripheral nerve block (PNB) regularly, 21.6% used continuous PNB techniques, and 4.6% used stimulating catheters. The primary source of training was residency programs. As regards PNB, the most common performed were interscalene (52.3%), axillary (45.1%), femoral (43.2%), and ankle block (43%). As regards the localisation technique employed, 16% used paraesthesia, 44.2% used a peripheral nerve stimulator, and 18.1% ultrasound guidance. Regional anaesthesia and PNB are commonly used among South American anaesthesiologists. Considering that each country has its own profile for use, this profile should guide training in clinical practice, especially in residency programs.

Sixty patients who were scheduled for elective surgery under general anaesthesia (30 males/30 females) were enrolled. Patients were randomly allocated to receive one of 15 combinations of drug levels. Baseline electroencephalograms (EEGs) were recorded for 5 minutes prior to administering the drugs. Patients received a targetcontrolled infusion at one of four predefined doses of propofol (high, 3 μg/mL; medium, 1.5 μg/mL; low, 0.5 μg/mL; or no drug) and of remifentanil (high, 6 or 8 ng/mL; medium, 4 ng/mL; low, 2 ng/mL; or no drug). The occurrence of muscle rigidity, apnoea, and loss of consciousness (LOC) was monitored, and EEGs were recorded during the drug administration phase. Electroencephalographic approximate entropy (ApEn) and temporal linear mode complexity (TLMC) parameters at baseline and under steady state conditions were calculated off-line. Response surfaces were developed to map the interaction between propofol and remifentanil to the probability of occurrence for quantal responses (muscle rigidity, apnoea, LOC) and ApEn and TLMC measurements. Model parameters were estimated using non-linear mixed effects modelling. The response surface revealed infraadditive and synergistic effects for muscle rigidity and apnoea, respectively. The effects of the combined drugs on LOC and EEG parameters (eg, ApEn and TLMC) were additive. The C50 estimates of remifentanil (ng/mL) and propofol (μg/mL) were 9.11 and 130 000 for muscle rigidity, 8.99 and 6.26 for apnoea, 13.9 and 3.04 for LOC, 23.4 and 10.4 for ApEn, and 14.8 and 6.51 for TLMC, respectively. The probability of occurrence for muscle rigidity declined when propofol was combined with remifentanil. © 2016 John Wiley & Sons Australia, Ltd.

Preoxygenation may lengthen the period before this happens. No scientific studies are published on preoxygenation in equine anaesthesia. To determine whether supplementation of oxygen at a flow rate of 15 l/min for 3 min via a nasal cannula before induction of general anaesthesia is effective in elevating the arterial partial pressure of oxygen (PaO2 ) directly after induction. Randomised, prospective clinical trial. A total of 18 American Society of Anesthesiologists physical status 1 or 2 adult horses undergoing elective anaesthesia were randomly allocated to one of 2 groups. The first group (control) received no oxygen supplementation before induction of general anaesthesia, whereas the second group (oxygen) did. All horses were anaesthetised with intravenous detomidine, butorphanol, ketamine, midazolam and isoflurane. Directly after induction (T = 0) and 30 min later (T = 30) an arterial blood sample was taken for blood gas analysis. At T = 30 an estimate of intrapulmonary shunt fraction (Qs/Qt) was calculated. At T = 0 arterial partial pressure of oxygen (PaO2 ) was significantly higher in the oxygen group compared with the control group (11.0 ± 2.6 kPa vs. 7.4 ± 1.6 kPa; mean ± s.d., P = 0.005) and at T = 30 differences were not statistically significant. Partial pressure of carbon dioxide (PaCO2 ) and Qs/Qt did not differ between groups. Supplementing oxygen by a nasal cannula before induction of general anaesthesia in horses is feasible and does effectively elevate the PaO2 immediately after induction. Future research is needed to determine whether supplementation of oxygen before induction of general anaesthesia in horses will affect outcomes. © 2015 EVJ Ltd.

We hypothesized that regional anaesthesia (RA) is associated with higher survival and fewer postoperative organ dysfunctions when compared with general anaesthesia (GA). We matched surgical procedures and type of anaesthesia using the US National Surgical Quality Improvement database, in which 264,421 received GA and 64,119 received RA. Procedures were matched according to Current Procedural Terminology (CPT) and ASA physical status classification. Our primary outcome was 30-day postoperative mortality and secondary outcomes were hospital length of stay, and postoperative organ system dysfunction. After matching, multiple regression analysis was used to examine associations between anaesthetic type and outcomes, adjusting for covariates. After matching and adjusting for covariates, type of anaesthesia did not significantly impact 30-day mortality. RA was significantly associated with increased likelihood of early discharge (HR 1.09; P< 0.001), 47% lower odds of intraoperative complications, and 24% lower odds of respiratory complications. RA was also associated with 16% lower odds of developing deep vein thrombosis and 15% lower odds of developing any one postoperative complication (OR 0.85; P < 0.001). There was no evidence of an effect of anaesthesia technique on postoperative MI, stroke, renal complications, pulmonary embolism or peripheral nerve injury. After adjusting for clinical and patient characteristic confounders, RA was associated with significantly lower odds of several postoperative complications, decreased hospital length of stay, but not mortality when compared with GA. © The Author 2016.

[1] would like to correct an error of transposition. In Table 1, the talk times and their p values have been transposed with the exception of at the top of the table ('all messages(') where the times, but not the p value were transposed. The corrected Table 1 is below. The discussion of the (slightly surprising) finding that the Traffic Light system led go-betweens to walk down the corridor faster is therefore wrong and the following sentences require correction: "The Traffic Lights tool also significantly reduced message delivery time by reducing the 'walk time'" This should read: "The Traffic Lights tool also significantly reduced message delivery time by reducing the 'talk time'" This sentence should be deleted: "Of interest, the time the go-between took to walk to deliver the message was affected by the urgency of the message, but use of the Traffic Lights tool significantly reduced this time, particularly for emergency messages" Should be replaced by: "The Traffic Lights tool led to the time taken to articulate all types of message being reduced by > 20 s."

The three causes of postoperative blindness are ischaemic optic neuropathy, central retinal artery thrombosis (these can exist in tandem and have been described as ischaemic oculopathies) and cortical blindness. This review aims to improve anaesthetists' knowledge of orbital anatomy, ocular physiology and the mechanisms of perioperative eye injuries to help reduce their occurrence.

Source: Anaesthesia and Intensive Care Medicine; Jan 2017; vol. 18 (no. 1); p. 37-40 Publication Date: Jan 2017 Publication Type(s): Journal: Review Abstract:Local anaesthesia is often the technique of choice for ophthalmic procedures performed on adults; however, general anaesthesia is usually required for procedures on children. The majority of paediatric patients are fit and healthy but there is a minority in whom the presenting eye complaint is related to a congenital disorder, which may have significant bearing on the conduct of anaesthesia. Management of the airway and presentation of a quiescent eye for surgery are key considerations, while control of the oculocardiac reflex and intraocular pressure (IOP) are important both intraoperatively and postoperatively. IOP is affected by almost all aspects of general anaesthesia and should be considered when choosing an anaesthetic technique. Ocular surgery is emetogenic and without prophylaxis is associated with a high incidence of postoperative nausea and vomiting which should be addressed to prevent problematic increase in intraocular pressure. Most procedures are associated with mild to moderate postoperative pain and can usually be managed with simple analgesia. Pain, but also the use of opioid analgesia, is a risk factor for postoperative nausea and vomiting. Examination under anaesthesia, intraocular surgery, correction of squint and emergency ophthalmic surgery each presents its own challenge and all are discussed.

Source: Anaesthesia and Intensive Care Medicine; Jan 2017; vol. 18 (no. 1); p. 41-43 Publication Date: Jan 2017 31 Publication Type(s): Journal: Review Abstract:Local anaesthesia is the technique of choice for a large number of ophthalmic procedures, including cataract surgery. For some procedures topical anaesthesia is sufficient; for more complex procedures a local anaesthetic block will be needed. Sharp needle techniques previously favoured, whilst still useful, have become less common than the cannula-based sub-Tenon's block. This provides favourable operating conditions with a lower risk of complications. Patients should be appropriately counselled regarding local anaesthesia early in their perioperative journey; combined with suitable preoperative assessment this provides high levels of patient satisfaction and limits interruptions to their usual routine.

Source: Anaesthesia and Intensive Care Medicine; Jan 2017; vol. 18 (no. 1); p. 33-36 Publication Date: Jan 2017 Publication Type(s): Journal: Review Abstract:Local anaesthesia for eye surgery is increasingly popular, but there will always be a need for general anaesthesia. Patients may refuse local anaesthesia, may be unable to keep still or lie flat for the duration of surgery or lack the mental facility to cooperate whilst awake. Young children and those with allergy to local anaesthetic also need general anaesthesia. Careful patient preparation is important before surgery. Glycaemic control in patients with diabetes, adjustments to warfarin or aspirin dosing, thromboembolic prophylaxis and preoperative fasting need to be considered. Eye surgery alone is rarely a true emergency, and surgery can usually wait until the patient's stomach is empty. Eye pathology requiring surgery is a feature of many medical conditions and syndromes. Many patients are elderly with ischaemic heart disease, hypertension, chronic obstructive pulmonary disease and renal impairment, which must be assessed before general anaesthesia. Systemic effects of ophthalmic medications, such as hypokalaemia caused by acetazolamide should be considered. A wide range of general anaesthetic techniques are suitable for eye surgery, but certain key points are relevant to specific operations. These include the oculo-cardiac reflex in strabismus and retinal surgery, the use of intraocular gas bubbles in vitreo-retinal operations, controlled hypotension in lacrimal, orbital and other oculoplastic procedures, and the high incidence of nausea after strabismus surgery. Total intravenous anaesthesia (TIVA) fulfils many of the requirements for the ideal anaesthetic technique for ophthalmic surgery. Blood pressure, heart rate and intraocular pressure are lowered. It is rapidly titratable and recovery is fast. Postoperative nausea is reduced and TIVA works well in patients with renal and hepatic disease. Remifentanil infusion allows nitrous oxide to be avoided and top-up doses of muscle relaxants to be minimized during ventilation. For most ophthalmic surgery, postoperative pain is mild and non-steroidal antiinflammatory drugs work well. Intraoperative sub-Tenon's local anaesthetic is useful.

In patients with underlying respiratory pathology, these changes in respiratory physiology may lead to clinical problems during the conduct of anaesthesia and the perioperative period.
