Objectives
Narrative objectives1
The objective is to predict hypotension after induction of general anesthesia by using deep learning with image information.
Basic objectives2
Others
Basic objectives -Others
In addition to numerical values such as test results, anesthesiologists sometimes use information such as waveforms contained in biometric images to understand the patient's condition. However, there have been few reports on predicting changes in the patient's condition using biometric imaging information. Therefore, we will create a model for predicting hypotension after induction of general anesthesia by using deep learning of biometric images, including the spectroscopic arterial pressure waveform during wakefulness, which has not been explicitly documented.

From the biometric images stored in the anesthesia recording system (ORSYS, PHILIPS), we will extract the observation arterial pressure ECG images for about 10 seconds before induction of general anesthesia to a USB with a password.
We classified the image data into two groups: positive for those who showed a decrease in blood pressure after the induction of general anesthesia and negative for those who did not.
Create an AI model using the positive and negative data, using 80% of the total data as train data.
AUC was calculated by drawing ROC curve using 20% of the total data as test data.
After induction of general anesthesia, arterial pressure and electrocardiographic images will be examined in the same way. This is to confirm the prediction accuracy for hypotension occurring in real time, and to evaluate whether AI can predict changes in arterial pressure waveform before and after the induction of general anesthesia.
The following information will be obtained from the medical record.
Preoperative information, Intraoperative information,Preoperative information and the amount of anesthetics will be compared between the two groups.
Based on the obtained data, we will examine the correlation with the decrease in blood pressure after the induction of general anesthesia using deep learning.
