Anesthesia means giving medicines to control pain and help people stay asleep during surgery. Keeping patients safe needs the right amount of medicine and careful watching of things like blood pressure, heart rate, and oxygen levels. For many years, early computer programs in anesthesia used strict rules they had to follow.
These rule-based systems helped make tasks more consistent by cutting down human mistakes. Machines could change anesthesia doses automatically within safe limits. This helped keep patients stable during operations. The systems also gave alerts to doctors and nurses about the patient’s condition.
One example was the SEDASYS® system, approved by the FDA in 2013. It was designed to give sedation based on preset rules. But it stopped being used in 2016 because it could not change to fit different patient needs. This happened because early systems could not learn or adapt beyond their original programming.
This showed we needed smarter AI models that could deal with more complex and changing clinical situations.
The next step in AI was deep learning. It is a part of machine learning where computers get better by studying large amounts of data without being told exactly what to do each time. These models find patterns and predict results by looking at millions of clinical records.
Along with deep learning, generative AI (GenAI) became important. GenAI is known for understanding and writing human-like text. But in healthcare, including anesthesia, it can also help analyze clinical notes, sort data, and predict health outcomes.
A 2024 review of 161 studies on GenAI in healthcare found that 87.6% showed GenAI improving clinical services. It does this by helping find knowledge, organizing complex data, and sorting useful info from large datasets. This is very useful in anesthesia where doctors need to handle a lot of patient information before, during, and after surgery.
GenAI models like ChatGPT-4 can classify how patients are doing before surgery with high accuracy. A study with 2,851 patients showed AI predictions were close to those made by expert anesthesiologists. This means AI can support doctors but does not replace their judgment.
Virginia Commonwealth University’s Department of Nurse Anesthesia is researching these AI uses to improve anesthesia care.
One useful AI advancement is closed-loop anesthesia systems. Unlike early rigid systems, these use real-time patient data to automatically adjust medicine doses. For example, they change anesthesia drugs and blood pressure medicine based on current patient vitals.
Recent studies show these AI systems keep patients more stable during surgery than manual control. They reduce the time patients spend with unsafe blood pressure and help patients recover faster after drugs like propofol and muscle relaxants.
By adjusting drug doses in real time, closed-loop systems reduce differences in how patients react. This makes anesthesia safer and outcomes more predictable. It also lowers the workload for doctors and nurses, letting them focus on other tasks while the AI controls drug delivery.
Experts remind us that AI should help doctors, not take over. Dr. Jiale (Gary) Hu says clinical experts must always watch AI and step in if needed.
AI is also changing anesthesia work behind the scenes. It helps automate office and admin tasks like scheduling, paperwork, patient communication, and handling electronic health records (EHRs).
With natural language processing and GenAI, AI assistants and chatbots can answer phone calls, book appointments, and respond to questions. This saves time for doctors and nurses to focus on patients.
AI helps anesthesia teams by quickly reviewing patient history, notes, and test results before surgery. This speeds up decisions and lowers delays caused by missing or old information.
IT staff also use AI to organize clinical data better, making it easier to find important info. AI can help predict how many surgeries will happen, so hospitals can plan staff schedules and manage resources well.
This kind of automation makes operations more efficient and improves patient experience by cutting down errors and delays.
For those running anesthesia services in U.S. hospitals—from small community centers to big academic centers—AI offers many advantages. AI helps standardize care while still allowing adjustments for each patient using flexible algorithms.
Spending on AI systems matches national goals to improve patient safety and reduce differences in surgical results. Because anesthesia rules can be complex, using AI backed by solid research can help hospitals meet rules and get proper approvals.
Health IT teams have an important job making sure AI tools work smoothly. They work with anesthesia staff, biomedical engineers, and vendors to connect AI with existing hospital systems. They also keep data secure, ensure data accuracy, and train staff on the new technology.
Hospitals can learn from research at places like Virginia Commonwealth University and experts such as Dr. Nickie Damico. These professionals remind us to keep AI as a helpful tool that improves care without replacing the knowledge of anesthesia providers.
Artificial intelligence in anesthesia has moved from simple rule-following systems to smart machines that learn from big clinical data sets and manage anesthesia in real time. Generative AI tools add value by helping organize and understand clinical information for better decision-making and smoother workflows.
For U.S. healthcare administrators, owners, and IT teams, knowing AI’s history and what it can do now helps with smart choices on adopting this technology. Using AI can improve patient safety and reduce work stress, leading to better anesthesia care today.
AI technologies enhance anesthesia delivery by supporting professionals through rule-based automation, improving patient safety, and ensuring consistent operation of complex biomedical devices.
AI has transitioned from traditional rule-based systems to deep learning and Generative AI (GenAI), enabling improved data management, predictive analytics, and the ability to analyze complex clinical notes.
GenAI allows healthcare professionals to interact with data in natural language, facilitating tasks like data search, classification, and summarization, thereby streamlining data management processes.
A systematic review found that 87.6% of studies indicated GenAI’s effectiveness in enhancing clinical services through improved knowledge access and data collation.
AI can analyze preoperative evaluation data and classify patients’ physical status, demonstrated through high concordance with expert assessments in recent studies.
Closed-loop systems automate anesthesia delivery based on real-time patient data, dynamically adjusting drug infusion rates to maintain optimal anesthesia depth and stability.
These systems significantly reduce intra-patient variability and allow for continuous physiological monitoring, thereby improving protocol compliance and patient outcomes during surgery.
Early systems like SEDASYS faced limitations due to inflexibility, leading to their discontinuation, highlighting the need for advancements incorporating deep learning.
Recent meta-analyses indicate that AI-powered closed-loop systems improve stability during anesthesia, shorten recovery times, and reduce time spent outside target blood pressure ranges.
AI is viewed as an augmentation rather than a replacement for human expertise, aiming to enhance efficiencies while emphasizing the need for human oversight in patient care.
