The application of intravenous general anesthesia under nasopharyngeal airway assisted ventilation undergoing ureteroscopic holmium laser lithotripsy: A prospective, single-center, controlled trial.

To observe the effect of intravenous general anesthesia under nasopharyngeal airway-assisted ventilation on patients undergoing ureteroscopic holmium laser lithotripsy. One hundred and twenty patients who underwent ureteroscopic holmium laser lithotripsy in our hospital were selected and randomly divided into nasopharyngeal airway group (research group) and laryngeal mask group (control group). These patients, respectively, received intravenous anesthesia under nasopharyngeal airway and laryngeal mask-assisted ventilation. The following evaluation indexes were compared and analyzed between the two groups, including anesthetic effect, hemodynamics, stress response, postoperative recovery, adverse reactions, etc. There were no significant differences in Visual Analog Scale, hemodynamics, and stress response between the two groups at each time point (P > 0.05). There were no significant differences in residence time and postoperative recovery time between the two groups (P > 0.05). The difference in airway establishment time between the two groups was statistically significant (P < 0.05), and cases with blood in the research group was significantly lower than those in the control group (P < 0.05). Patient satisfaction in research group was significantly higher than those in the control group (P < 0.05). The clinical effect of intravenous general anesthesia under nasopharyngeal airway-assisted ventilation in ureteroscopic holmium laser lithotripsy is significant, which helps to stabilize patients' hemodynamics, reduce their stress response and adverse reactions, and improve the satisfaction rate of patient.
