Anesthesia prediction involves a complex interplay of patient-specific factors, medical histories, and the intricacies of surgical procedures. The current standard practices often face challenges associated with the inherent variability in patient responses to anesthesia. Thisvariabilitymakesitchallengingtopredicttheoptimal type and dosage accurately, leading to potential risks, prolongedrecoverytimes,andincreasedhealthcarecosts.

In the pre-2000s, machine learning in medicine was mostly employed for fundamental applications such as diagnostic systems and decision support tools. Systems were primitive, frequently rule-based, and lacked the sophisticationfoundtoday

Withtheintroductionofelectronichealthrecords(EHRs), machine learning began to integrate patient data into predictive analytics. Algorithms helped in disease prognosis, treatment planning, and patient outcome forecasting, laying the framework for personalized medicine.

Deep learning emerged in the 2010s, ushering in a substantial transformation. Convolutional Neural Networks (CNNs) have transformed medical imaging, improving diagnosis accuracy in domains such as radiology, pathology, and cardiology, and in some cases outperforminghumanskills.

Precision medicine relied heavily on machine learning, which used genomic data to personalize treatments for eachpatient.Algorithmsfoundgeneticmarkers,predicted illness susceptibility, and optimised medication therapy, resultinginmoreeffectiveandtailoredtreatments.

NLP has developed as an effective method for extracting unstructured clinical data from medical records, research literature, and social media. Sentiment analysis, information extraction, and summarization improved clinical decision-making, patient monitoring, and medicationdiscovery.
