Artificial intelligence (AI) is based on reinforced learning and revolves around the usage of algorithms. AI works like the brain's complex neural network and uses artificial 'neurons' that learn by comparing themselves to the desired output and 'reinforcing' useful connections, thus creating the basis of the artificial neural network approach. The healthcare field generates 'big data' that includes all records. The vast spectrum of AI and the ability of deep neural networks to analyse perioperative data are being utilised for predicting outcomes and reducing healthcare costs. The involvement of AI in anaesthesia practice includes preoperative assessment and risk predictions, airway management using intubating robots, managing effective concentration of anaesthesia by target-controlled infusion, monitoring the depth of anaesthesia (DOA) and early detection of anaesthesia and surgical complications. Postoperatively, AI has shown a role in reducing surgical site infections and intraabdominal infections and identifying anastomotic leaks.
In this issue of 'Airway', Senthilnathan and Kundra discuss the role of machine learning (ML) and AI in the field of airway management and anaesthesia practice by supervised ML (the machine predicts the known outcome, e.g., regression algorithms) and unsupervised ML (no predefined outcome). They mention that the prediction of the difficult airway (DA) by ML algorithms is one promising tool that can successfully predict DA, difficult laryngoscopy and difficult intubation, which can be achieved by incorporating all the DA predictors (physical and radiological).
Senthilnathan and Kundra also highlight the importance of ML and AI in anaesthesia practice and intensive care units by a decision tree, a supervised ML technique for analysing classification-related tree and regression problems. The outcome variable is categorical in the classification tree and continuous in the regression tree.
Anaesthesia is the one field, which has the maximum scope of ML and AI. The use of high technology in anaesthesia and intensive care units makes it relatively easy to collect and analyse lots of real-time unbiased data directly from multipara monitors, infusion devices, drug-delivery systems, closed-loop anaesthesia delivery systems (CLADS) and electronic medical records. Ramaswamy et al. used ML to analyse the complex EEG signal after giving sedation and evaluated the level of sedation in 102 volunteers. The outputs were integrated into a complex yet defined algorithm to continuously estimate the level of sedation without bias and interobserver variability and without stimulation of the subject.
ML is done in three processes: (a) Big Data Analysis-Data Mining-Cluster Analysis: in this, the large database is analysed (big data analysis), and the patterns of and between variables observed (data mining) to make or recognise a cluster of data for further analysis (cluster analysis); (b) Analysis of Complex Data from clinical sources such as multipara monitor (haemodynamic parameters, DOA, neuromuscular monitoring, etc.), EEG, degree of sedation, etc., and (c) Model or Algorithm Description for real-time prediction or estimation of a particular outcome or event.
ML has very high analytical ability, even better than many statistical and modelling tools. The main issue is the 'black box problem' of AI in healthcare, which is the inability of patients or healthcare providers to understand the outcome or event of the ML or AI which is based on unspecified mathematical functions, algorithms or models.
Anaesthesia practices are like the aviation sector, with considerable risk from induction to maintenance to recovery. For a safe perioperative period, Gambus and Jaramillo described 'reactive, proactive and predictive' model, where the 'proactive approach' prevents an adverse outcome or event by preparing the required things beforehand like checking the anaesthesia machine, drug preparation, assessment of the patient, etc. The 'reactive approach' is reacting to certain critical events. The 'predictive approach' provides information and alerts the physician about the anticipated adverse outcomes or critical events to take preemptive preventive action. One example of the predictive approach is using Hypotension Prediction Index in the perioperative period, which alerts the physician about the possibility of hypotension.
The predictive approach improves the proactive practice using a model to assess the risk of adverse events or outcomes (risk of DA, etc). The better predictive model is one that can have an effect on the reactive approach by providing information about the possibility of an adverse event or outcome before its occurrence (HPI model for 'risk of hypotension', the bispectral index for 'risk of deep sedation').
Brown et al. proposed an AI system that identifies the ETT, trachea and carina using a 'semantically embedded neural network' that combines deep convolutional neural networks. It provides two forms of decision support: ETT detection assistance and position check alerts. It focuses on supporting the intensive care unit physician at the point of care. Based on the relationships defined in the semantic network, segmentation proceeds in a hierarchical fashion, with the segmentation of the trachea spatially guiding the convolutional neural networks detecting the carina and ETT. Spatial relationships are used directly to define the ETT tip and safe zone regions.
Mlodzinski et al. surveyed the use of ML/AI for a novel intubation prediction tool amongst critical care physicians (through email) and critical care providers and non-providers by one open social media survey. They found that many critical care providers and non-providers have positive perceptions of ML/AI-based tools. Critical care providers were interested in tools to predict the need for intubation.
The use of robots in anaesthesia practice is not very new. The first robotic intubation was done more than a decade ago using the da Vinci surgical system (multiple arms). The Kepler intubation system is a single robotic arm controlled by a joystick for remote intubation. The Magellan system has been used for regional techniques with a block needle mounted on a robotic arm. It was used with a good success rate and less interoperator variability. Robotic endoscope-automated laryngeal imaging for tracheal intubation is a video-endoscopic stylet that guides endotracheal intubation.
There are other uses of ML/AI in airway management, such as VivaSight single-lumen ETT and VivaSight double-lumen tube.
In conclusion, the use of ML algorithms and AI in anaesthesia practice is increasing, and the future is with AI. It opens the door to improved close monitoring, better drug and anaesthetic delivery, preemptive approach to maintain haemodynamics and less airway catastrophe by better assessment tools and intubation assistance.
