Ấn bản này toàn diện hơn nhiều so với những nỗ lực trước đây của chúng tôi và bao gồm hơn và có nhiều trang, bảng, sơ đồ và hình minh họa màu hơn. Văn bản này cũng được tham chiếu một cách toàn diện. Như trong các lần xuất bản trước, có một số lặp lại và đó là điều không thể tránh khỏi. Tuy nhiên, thật thú vị khi so sánh kinh nghiệm của các bác sĩ gây mê từ khắp nơi trên thế giới và từ bên ngoài chuyên ngành của chúng tôi. Độc tính toàn thân của thuốc gây mê cục bộ (CUỐI CÙNG) là một chủ đề rất phổ biến đối với tất cả những người thực hành Gây mê cục bộ và vùng, và chúng tôi đã học được rất nhiều về cách phòng ngừa và điều trị căn bệnh này trong 30 năm qua. May mắn thay, hầu hết các biến chứng mà chúng tôi đã thảo luận là rất hiếm và chúng tôi thường xuyên phải gánh chịu trách nhiệm cho những chấn thương mà chúng tôi không gây ra ngay từ đầu. Trọng tâm chính của chúng tôi là an toàn và phòng ngừa thương tích trong thực hành gây tê cục bộ và khu vực, và chúng tôi đã kêu gọi nhiều chuyên gia từ khắp nơi trên thế giới chia sẻ kinh nghiệm của họ với chúng tôi. Chúng tôi hy vọng bạn đánh giá cao những thay đổi mà chúng tôi có và như mọi khi, chúng tôi hoan nghênh các phê bình và đề xuất của bạn để cải thiện. Có một thay đổi quan trọng khác mà tôi đã thực hiện trong ấn bản này và đó là tôi đã mời đồng nghiệp và bạn bè của tôi từ Khoa Gây mê và Y học Đau từ Đại học Alberta cùng biên tập ấn bản này của văn bản với tôi. Ông đã đóng góp rất nhiều vào kiến thức của chúng tôi về gây tê cục bộ và khu vực trong hai thập kỷ qua và đã giúp rất nhiều cho phiên bản mới nhất này.

Finucane, MB, BCh, BAO, FRCA, FRCPC Ban C.H. Tsui, MSc (Pharm), MD, FRCPC www.ajlobby.com Preface We are now ready to publish the third edition of Complications of Regional Anesthesia which was first published 17 years ago The title remains the same but we have added the subtitle, Principles of Safe Practice in Local and Regional Anesthesia, to stress the relatively new emphasis and importance on safety and prevention and to broaden our horizons to include some discussion about the practice and the administration of not just Regional but also Local Anesthesia We have made some significant changes to the book which we hope you approve First of all this is a much more comprehensive edition going from 24 to 35 chapters, and we have also divided the book into seven separate parts based mostly on logic In the opening part entitled General considerations, we started out with a chapter on the History of Regional Anesthesia which seemed like a good place to start We also addressed the issue of Safety of Regional Anesthesia It is difficult to discuss much about regional and local anesthesia without mentioning toxicity of local anesthetics which has been a problem with regional and local anesthesia since its inception more than 130 years ago, and we finished up that section with a good discussion of Outcomes comparing Regional and General Anesthesia In the second part we addressed Special considerations, which includes a chapter on Mechanisms of Nerve injury, Infection, Catheter techniques, and the whole issue of regional anesthesia in the presence of neurologic disease and how to evaluate neurologic injury following regional anesthesia We then dedicated several chapters to Specific blocks involving anatomic regions of the body specifically addressing safety and management of adverse events We dedicated the next part to specific Patient Populations—the young, the old, the pregnant, obese, and those suffering from chronic pain The next part is new territory for us and is entitled Special Environments We invited a group of practitioners, mostly surgeons, who frequently use local anesthetics in their practices, to share their expertise and experiences with us Among this group of specialists are dentists, ophthalmologists, emergency room physicians, orthopedists, and plastic surgeons We have a lot to learn by sharing our experiences using local and regional anesthesia with specialists outside our own discipline and they from us We dedicated a part to Morbidity Studies and this part includes writers from across the world adding an International flavor, as we are sometimes accused of being too insular in North America We dedicated the final part to Medical Legal Aspects of Local and Regional Anesthesia, which we must realistically face in the modern world of this twenty-first century Labat, in the 1920s, was the first fully trained specialist in Regional Anesthesia, and he influenced the leaders of this new emerging specialty of anesthesiology to use regional anesthesia in their practices Most anesthesiologists at that time opted for general anesthesia because of its predictability Tremendous advances have been made in Regional Anesthesia in the past 30 or 40 years, so much so that most anesthesiologists in the modern era have become interested in regional anesthesia again because there is far more predictability in the practice of regional anesthesia than ever before We can now actually see what we are doing instead of blindly seeking neural targets, based on our knowledge of anatomy Most anesthesiologists fully appreciate the enormous benefits of regional anesthesia to patients especially in the postoperative period but also long term However, despite good practice, we encounter problems vii www.ajlobby.com viii Preface and unforeseen circumstances, so practitioners must be fully aware of the many pitfalls and complications associated with the practice of regional anesthesia even though we have made enormous advances in recent years This edition is much more comprehensive than our previous efforts and more inclusive and there are more pages, tables, diagrams, and colored illustrations This text is also comprehensively referenced As in previous editions, there is some repetition and that is inevitable However, it is refreshing to compare anesthesia practitioners’ experiences from around the world and from outside our own discipline Local Anesthetic Systemic Toxicity (LAST) is a very common theme among all who practice Local and Regional Anesthesia, and we have learned a lot about prevention and treatment of this malady in the past 30 years Fortunately most of the complications we have discussed are rare and all too often we appear to shoulder the blame for injuries that we did not cause in the first place Our main emphasis is on safety and prevention of injury in the practice of local and regional anesthesia, and we have called upon a great variety of experts from around the world to share their experiences with us We hope you appreciate the changes we have and as always we welcome your critique and recommendations for improvement There is one other important change I have made in this edition and that is I have invited my colleague and friend from the Department of Anesthesiology and Pain Medicine from the University of Alberta to co-edit this edition of the text with me He has contributed enormously to our knowledge of local and regional anesthesia in the past two decades and helped a great deal with this latest version Edmonton, AB, Canada Stanford, CA, USA Brendan T.

Smedstad and Brendan T Finucane www.ajlobby.com 487 35 Medical Legal Aspects of Regional Anesthesia: Legal Perspective then the claimant can use them to argue that the care provided fell below the standard expected at law The guidelines are used in this way as evidence of what a responsible body of medical practitioners considers a reasonable standard of care and therefore an independent marker of safe practice Practicing outside the guidelines will not however necessarily be sufficient for a claimant to prove a breach of duty There may be a number of grounds on which the anesthetist can argue that the guidelines should not be followed, or at least should not have been followed in that particular case An example of a claim founded on practice outside the guidelines appeared in a 2012 editorial in the British Journal of Anaesthesia [9] In that case, the patient suffered a very rare complication of a central line insertion (a fistula between the internal jugular and the vertebral artery), resulting from an inadvertent arterial puncture during insertion of a central line without ultrasound guidance She was left with a small visual field defect after the repair of the fistula Two years before the incident, the National Institute of Clinical Excellence (NICE) guidelines had recommended that all central lines be placed under ultrasound guidance The patient, citing failure to follow the NICE guideline, sued for malpractice, arguing the complication may have been avoided if the guidelines had been followed The anesthetist’s counsel argued that the approach chosen “was a recognised technique, the one he was most familiar with and therefore the technique that would be expected to minimise the risk of harm to the patient” [9] and that a significant number of other anesthetists were practicing that way The defence also referred to the fact that implementing guidelines within 3 months of publication (as is recommended for NICE guidelines) is not always possible in reality The claimant withdrew the case We not know why but we can speculate that, having heard the evidence that supported deviation from the guidelines, the claimant was not confident of success The case illustrates that deviation from a guideline can be defended by justifying an alternative technique and the practical difficulty of implementing the guideline Another means of justifying deviation from the guideline is to directly discredit the guideline This would involve calling expert evidence that the guidelines are out of date or not supported by “… the rigorous methodology that would justify the authority they profess to hold, be this in terms of their influence on clinical practice, or their use in establishing legal standards” [9] Additionally, if in a group practice, evidence of discussion about this topic, and a group decision to practice outside the guidelines and reasons for doing that would be evidence that may help persuade a decision-maker that a reasonable standard of care had been provided The more well recognized the guidelines are, the more difficult this will be to Lars’s practice deviated from the ASRA guidelines so this line of argument may be difficult, depending on where he is practicing Lars could bring evidence to persuade the decision-maker that in the case of this particular patient or in this particular hospital, it was reasonable to deviate from the guidelines For example, Lars made a record of the consent That record may be helpful in defending his practice if it records that he documented the possibility of complications and the benefits of undertaking the procedure this way, particularly if he noted this was outside the guidelines but had good reason for doing so For example, “Discussed the increased risk of nerve damage when the block was done under general anesthetic The patient wants a block but would prefer it be done under general anesthetic, and understands the increased risk involved.” Alternatively, an anesthetist might be able to bring evidence that the hospital he was practicing in did not provide the equipment or training to enable her or him to follow the guideline As is apparent from this discussion, it will depend on the guidelines and on the evidence that you can bring to prove your practice outside them was still a reasonable standard of care Documentation of a considered decision is very helpful Where possible however, it is safer to practice within some well-recognized guidelines in the area, e.g., ASRA for regional anesthesia Rather than having to provide evidence as to why you practiced outside the guidelines, you can instead use the guidelines as evidence that your care met the standard expected at law The Emotional Toll of a Claim The stress and anger that Lars experienced after being served with a claim for malpractice is a common experience In the United States, negative emotional reaction to being sued has even been named: Medical Malpractice Stress Syndrome (MMSS) [10, 11] Lawyers are fond of telling their clients to try and be objective and retain some emotional distance from their case While emotional detachment is often considered a key attribute of being a professional, and likely something you strive for in practice, it is probably unattainable when you are at the subject of the claim Discussions with your lawyer will help to educate you about the legal process, the evidence that is required, and your prospects of a successful defence This in itself can help reduce stress, as it increases a sense of control and reduces panic However, simply putting aside the emotional response or striving to be detached is unlikely to be successful and may be harmful The literature on MMSS has some useful practical suggestions for managing stress and seeking support, including surrounding yourself with trusted advisers, maintaining other interests (such as sport and hobbies) and taking an active role in your defence www.ajlobby.com 488 B Toy-Cronin and K Byrne Conclusion A claim of malpractice is just that, a claim Even if you practice without breaching your duty of care towards your patients, you are not immune from a claim being made against you Several things can help protect you from a claim: Familiarize yourself with the law in your country about what constitutes valid consent Your insurer will probably publish this information Engage with patients during consent and listen carefully to what they say Warn the patient of the risks of nerve injury and, particularly in obstetric anesthesia, incomplete blocks These are the most common sources of claims Be courteous and respectful Patients are less likely to make claims if they have been treated with dignity If you are the subject of a claim, then your lawyer will be interested in evidence Lawyers need to be able to present evidence that counters the claimant’s version of events For example, evidence of consent, evidence of thoughtful deviation from guidelines, evidence of handover of care to another practitioner It is for this reason that doctors are frequently admonished to keep careful records They are evidence that can clear up misunderstandings and end a claim Therefore, Keep thorough records If you are notified of a claim, then keep these points in mind: Do not alter records Call your insurer Choose a lawyer (this may have to be done in consultation with your insurer): (a) Make sure the lawyer has expertise in the area (b) If there is a co-accused (such as the hospital or another practitioner), consider whether you need a separate lawyer, e.g., if your defence is that the other practitioner was at fault, not you, you need a separate lawyer Be honest with your lawyer and provide him or her with accurate information, even if it does not show you in the best light Seek support from your family, friends, and colleagues References Cook TM, Bland L, Mihai R, Scott S.
