Analysis of Perioperative Patient Adverse Event Reports and Anesthesia Safety Management in an Anesthesia Department of a Tertiary A Hospital in 2019-2020

Objective: To analyze the characteristics of anesthesia adverse events in our department and propose measures for anesthesia safety management, to achieve better improvement of medical quality and promote medical safety. Methods: A total of 589 cases of anesthesia adverse events were collated and analyzed, including the time period of anesthesia adverse events and ASA (American Society of Aneshesiologists) classification of anesthesia adverse events. Results: The anesthesia induction and awakening periods were the main time periods for the occurrence of anesthesia adverse events, other human factors were the main reasons for the occurrence of anesthesia adverse events, and ASA grading II and III surgical patients accounted for the main proportion (mainly because of the heavy proportion of II and III surgical patients). Conclusion: Understanding the causes of adverse anesthesia events and implementing strict anesthesia safety management measures are conducive to reducing the occurrence of adverse anesthesia events and improving the safety of anesthesia.

Tribute to Dr. Takuo Aoyagi, inventor of pulse oximetry

Introduction Dr. Takuo Aoyagi invented pulse oximetry in 1974. Pulse oximeters are widely used worldwide, most recently making headlines during the COVID-19 pandemic. Dr. Aoyagi passed away on April 18, 2020, aware of the significance of his invention, but still actively searching for the theory that would take his invention to new heights. Method Many people who knew Dr. Aoyagi, or knew of him and his invention, agreed to participate in this tribute to his work. The authors, from Japan and around the world, represent all aspects of the development of medical devices, including scientists and engineers, clinicians, academics, business people, and clinical practitioners. Results While the idea of pulse oximetry originated in Japan, device development lagged in Japan due to a lack of business, clinical, and academic interest. Awareness of the importance of anesthesia safety in the US, due to academic foresight and media attention, in combination with excellence in technological innovation, led to widespread use of pulse oximetry around the world. Conclusion Dr. Aoyagi’s final wish was to find a theory of pulse oximetry. We hope this tribute to him and his invention will inspire a new generation of scientists, clinicians, and related organizations to secure the foundation of the theory.

The current state of anesthesia safety in a third world country: a cross-sectional survey among anesthesia providers in Ethiopia

Background Improving patient safety during anesthesia and surgery becomes a major global public health issue due to the increasing in surgical burden. Anesthesia is delivered safely in developed countries, but its safety is hampered by complex problems in third world countries. This survey assesses the unmet anesthesia needs of one of a third world country, Ethiopia. Methods A cross-sectional survey was conducted in Amhara region of Ethiopia from 15/12/2019 to 30/1/2020. All 81 hospitals of the region were stratified by their level as district, general, and referral hospital. The study was conducted in 66 hospitals. The number of hospitals from each strata were calculated by proportional sampling technique resulting; five referral, three general, and fifty eight primary hospitals. Each hospital from each strata was selected by convenience. Each anesthesia provider for the survey was selected randomly from each hospital and questionnaires were distributed. The minimum expected safe anesthesia requirements were taken from World Health Organization-World Federation of Societies of Anesthesiologists International Standard and Ethiopian Hospitals Standard. Anesthesia practice was expected safe if the minimum requirements were practiced always (100%) in each hospital. P < 0.05 with 95% confidence interval were used to compare the safety of anesthesia between higher and lower level hospitals. Results Seventy eight (88.6%) anesthesia providers working in 62 hospitals responded to the survey. On aggregate, 36 (58%) hospitals from the total 62 hospitals have met the minimum expected safe anesthesia requirements. Among the different variables assessed; professional aspects 32 (52.45%), medication and intravenous fluid 33 (53.36%), equipment and facilities 33 (52.56%), patient monitoring 43(68.88%), and anesthesia conduct 38 (62.1%) of surveyed hospitals have met the minimum requirements. Anesthesia safety is relatively higher in higher level hospitals (general and referral) 6 (75%) when compared to district hospitals 30 (55.5%), P < 0.001. Conclusion Anesthesia safety in Ethiopia appears challenged by substandard continuous medical education and continuous professional development practice, and limited availability of some essential equipment and medications. Patient monitoring and anesthesia conduct are relatively good, but World Health Organization surgical safety checklist application and postoperative pain management are very low, affecting the delivery of safe anesthesia conduct.

Anesthesia safety standards for operating rooms of small hospitals and surgery clinics

Access to surgical care and essential anesthesia is an integral part of universal health coverage. Also, increasing access to surgical care depends on a parallel increase in access to safe anesthesia. Today, five billion people (more than two-thirds of the world’s population) still do not have adequate, quality surgery and anesthesia care at the right time. Therefore, the World Federation of Societies of Anesthesiologists and the World Health Organization developed the International Standards for Safe Practice of Anesthesia. The standards include the following components, which are essential for the safety of patients undergoing surgical procedures: professional expertise, facilities and equipment, medications and intravenous fluids, monitoring, and anesthesia. In this article, it is emphasized that wherever and whenever possible, anesthesia should be provided, led, or overseen by an anesthesiologist. It is also strongly recommended that essential equipment is in place and adequate training to handle it safely has been provided. Unfortunately, some operating rooms of small hospitals and clinics does not meet the above standards. It may be difficult for each hospital to manage autonomously due to the lack of a unified checklist for essential standardized requirements. By introducing appropriate anesthesia safety standards in the operating rooms of small hospitals and surgery clinics, it will be possible to increase patient safety during surgery performed under general anesthesia, deep sedation, moderate sedation, or regional anesthesia. Through this process, it is expected that the mortality and morbidity rate of unexpected surgery patients can be minimized.

Office Laser Laryngology: A Paradigm Shift

Objectives: To present the value of office-based laryngological procedures as an effective alternative method to the treatment of benign and malignant laryngeal pathologies. Methods: We have reviewed the technological advancements of fiber-guided laser systems, fiberoptic endoscopes, and high-definition imaging systems that have enabled office-based laryngological procedures. We describe the importance of case and patient selection, the available laser systems, and the technique applied. Results: Several benign and malignant pathologies can be now treated in the office under local anesthesia with angiolytic or thermocoagulative lasers and with success rate comparable to that of general anesthesia. Safety guidelines and laser precautions must be implemented invariably to protect the patient and caregivers from the untoward effects of laser. Although there is considerable reduction of cost with office procedures, there are risks of undertreatment, increased repeatability, as well as tissue edema from the burning effect. Conclusions: The low learning curve, high patient satisfaction rate, and excellent results indicate that in-office laser procedures have become an effective weapon in our armamentarium.

Can Ultrasound Guided Regional Anesthesia Improve Rural Anesthesia Services and Address Safety Issues in Low Income Country? Perspective from Nepal

Provision of anesthesia services in a deprived area particularly in low income countries is a major challenge all over the globe. Along with issues of manpower, logistics, services, there lies agendas of safety and accuracy while delivering the services. With rise in ultrasound use in regional anesthesia, pain and perioperative care, it is prudent that some of these issues can be addressed with proper training, mentoring and monitoring. The global idea needs to be implemented locally to reach out to huge volume of patients who are inadequately treated for the various painful conditions. A group of regional enthusiasts from Nepal takes the vision and mission in Nepalese context to address the issues.
