Abstract:
Objective:To observe the effectiveness and safety of the application of Wei nasal jet tube(WNJT)in anesthesia induction for patients with extensive facial burns.Methods:A total of 60 patients who underwent multiple systemic scab removal and skin graft-ing surgery in our hospital from July 2021 to July 2023 were enrolled in this study.The patients were 18-60 years of age,with a body mass index of 18-29 kg/m2,ASA II or III,and Mallampati I-III.Using a random number table method,the patients were divided into WNJT ventilation group(W group)and mask ventilation group(M group),with 30 cases in each group.Before anesthesia induction,WNJT was inserted into one side of the nasal cavity for hand controlled normal frequency supraglottic jet ventilation in group W pa-tients,while oxygen ventilation was administered to group M patients through conventional two-hand clasped face masks.After 5 min,tracheal intubation was performed under a visual laryngoscope.The mean amplitude of diaphragm fluctuations,end expiratory carbon dioxide partial pressure(PETCO2),and blood oxygen saturation(SpO2)measured by ultrasound were recorded during spontaneous respi-ration at 5 min of oxygenation and nitrogen removal(T0),as well as at 1 min(T1),2 min(T2),3 min(T3),4 min(T4),and 5 min(T5,im-mediately before intubation)of anesthetic induction.Arterial blood gas(PaO2 and PaCO2)at T0 and T5 were measured.Heart rate(HR)and mean arterial pressure(MAP)were recorded at T0-T5 in both groups of patients.The occurrence of postoperative pharyngeal pain,facial or mandibular angle bleeding,gastrointestinal bloating,and nasal mucosal bleeding were recorded in both groups of pa-tients.Results:At T0,there were no statistically significant differences in mean amplitude of diaphragm fluctuations,HR,MAP,PaO2,PaCO2,PETCO2,and SpO2 between the two groups of patients.At T1-T5,the HR and MAP of patients in the W group were significantly lower than those in the M group(P<0.05).At T5,the PaO2 of patients in the W group was significantly higher than that in the M group,while the PaCO2 and PETCO2 were significantly lower than those in the M group(P<0.05).However,the difference in SpO2 was not sta-tistically significant.The W group had less facial or mandibular angle bleeding and postoperative gastrointestinal bloating than the M group,and the differences were statistically significant(P<0.05).There were no statistically significant differences between the two groups of patients in postoperative pharyngitis and nasal mucosal bleeding(P>0.05).Conclusion:During general anesthesia induction in patients with extensive facial burns,WNJT has the advantages of good ventilation effect,high safety,less complications such as gas-trointestinal bloating and facial or mandibular angle bleeding,and more stable hemodynamics.WNJT has good application prospects in clinical anesthesia.
