Clinical Study Of Tracheal Tube Supraglottic Ventilation In Painless Gastroscopy For High-risk Patients With Difficult Airway

Objective:Observe the safety and effectiveness of high-risk patients with difficult airways in the treatment of tracheal catheter supraglottic ventilation for painless gastroscopy.Methods:60 patients with difficult airway high-risk patients who underwent elective painless gastroscopy at Yichun City People's Hospital from January 2019 to December 2019 were selected to perform transtracheal duct supraglottic ventilation and traditional ventilation by random grouping.Comparison,mainly comparing the average arterial pressure,heart rate,blood oxygen saturation,blood gas analysis and other indicators of the two groups of patients,comparing the anesthesia dose,painless gastroscopy time,recovery time and examination interruption of the two groups of patients,endoscopist,anesthesia The satisfaction and adverse reactions of doctors and patients,clarify the safety and effectiveness of tracheal catheter supraglottic ventilation in improving painless gastroscopy for diagnosis and treatment of ventilation difficulties,and evaluate the value of tracheal catheter supraglottic ventilation in clinically difficult airways.Results:1.The two groups of patients observed the changes of hemodynamic parameters before,during and after painless gastroscopy,and found that the average arterial pressure and heart rate of the two groups of patients decreased briefly after induction of anesthesia.Significant difference(P>0.05),the proportion of patients in group A requiring emergency treatment was significantly lower than that in group B(P<0.05);the postoperative arterial blood carbon dioxide partial pressure in group A was 50±6mmHg,and the postoperative arteries in group B The partial pressure of blood carbon dioxide was 63±1mmHg,and there was a significant difference in the partial pressure of arterial blood carbon dioxide between the two groups of patients(P<0.05).2.A statistical analysis of the anesthesia dose,painless gastroscopy time and recovery time of the two groups of patients was found by t test analysis,and there was no significant difference in the anesthesia dose,gastroscopy time and recovery time of the two groups of patients(P>0.05);3.The satisfaction of the endoscopy doctors,anesthesiologists and patients in the two groups was investigated.The satisfaction of the doctors and anesthesiologists in group A was significantly higher than that in group B,with statistical difference(P<0.05),the satisfaction of patients in group A Compared with group B,the difference was not significant(P>0.05);4.Patients in group A need to raise the mandible in 0 cases,mask pressurized oxygen in 0 cases and tracheal intubation in 0 cases,use anesthesia machine in 3 cases,group B patients need to raise the mandible in 10 cases,and mask pressurize oxygen in 10 Cases and 4 cases of tracheal intubation,4 cases using anesthesia machine,the proportion of patients in group A that required emergency treatment was significantly lower than that in group B(P<0.05).Adverse reactions occurred in 5 patients in group A and 4 patients in group B,which accounted for a low proportion of the total enrollment,and the difference between the two groups was not significant(P>0.05).Conclusion:1.Tracheal tube supraglottic ventilation can effectively improve patients' hypoxia and reduce the occurrence of emergencies.2.The tracheal tube supraglottic ventilation can be connected to anesthesia machine to reduce the interruption rate of examination.3.Ventilation of tracheal tube glottis can reduce carbon dioxide accumulation.
