| Objective To evaluate the safety and feasibility of WEI NASAL JET in supraglottic jet ventilation before endotracheal intubation in snoring patients. Methods From January to November 2019, 50 snoring patients were selected for general anesthesia in the 910 Hospital of the PLA and divided into two groups based on random number table method: WEI NASAL JET group (W group,n=25) and buckle mask ventilation group(M group, n=25).After anesthesia,the patients in group W were inserted into the WEI NASAL JET, while those in group M received ventilation with double-hand buckle mask.Tracheal intubation was performed 5 min later.5 min spontaneous breathing after nitrogen removal by oxygen supply(T0), after no spontaneous breathing:1min(T1),2 min (T2),3 min (T3)and 4 min(T4) and immediately after intubation (T5),ultrasound was used to measure the amplitude of diaphragm motion induced by respiratory movement.SpO2<90% and fluctuation in mean arterial pressure and heart rate ≥ 20% of baseline before operation were observed.The development of ventilation-related complications was also recorded. Results There was no significant difference in respiratory movement amplitude, PaO2, PaCO2 and PETCO2 between the two groups at T0(P>0.05); In group W, the amplitude of diaphragmatic respiratory movement and PaO2 were higher;PaCO2 and PETCO2 were lower in group W, and the difference was statistically significant(P<0.05). Compared with T0, in T1～T5 the amplitude of diaphragmatic respiratory movement and PaO2 increased, while PaCO2 and PETCO2 decreased, and the difference was statistically significant(P<0.05).In addition, there was interaction between grouping and time on each index, and the difference was statistically significant(P<0.05).The incidence of skin redness,swelling and congestion, gastrointestinal flatulence in group W was lower than that in group M(P<0.05). Conclusions Supraglottic jet ventilation on WEI NASAL JET is safe and can provide satisfactory effect on snoring patients with obesity before tracheal intubation. |
