Optical medical equipment application and observing the occurrence of hypotension in elderly patients after general anesthesia induction through arteriovenous ultrasound parameters

Induced hypotension after intraoperative general anesthesia can lead to various complications, affecting the prognosis and postoperative recovery. Injecting too much fluid into a patient during surgery can increase circulating pressure, causing tissue edema and even organ failure. This condition is especially common in elderly patients. The application of optical medical devices has shown great potential in the medical field. However, in older patients, there is a higher incidence of hypotension after general anesthesia, which may negatively affect the procedure and the patient's health status. The purpose of this study was to investigate the application of optical medical devices in observing hypotension after general anesthesia in elderly patients in order to better understand and prevent the occurrence of this complication. This study selected 30 elderly patients who underwent surgery in a certain hospital as the study object. FT3, FT4, and TSH were 4.672 +/- 0.780 pmol/L, 16.924 +/- 2.185 pmol/L, and 1.912 (1.255, 2.790) mu IU/ml, respectively; After anesthesia induction, the inner diameter of the left and right common carotid arteries significantly decreased (P < 0.05), with values of 5.871 +/- 0.461 and 5.775 +/- 0.633, respectively; The induced IVCe, IVCi, and CI showed significant changes, with IVCe and CI being 1.882 +/- 0.200 and 36.898 +/- 4.685, respectively. Optical medical devices have the potential to observe and monitor hypotension after general anesthesia in elderly patients. By observing the changes in the parameters of arteriovenous ultrasound, the risk of hypotension can be grasped earlier and corresponding preventive measures can be taken to improve the safety of surgical procedures and the health of elderly patients.
