Efficacy of jaw thrust device in the upper airway obstruction / 中华麻醉学杂志

ABSTRACT

Objective To evaluate the efficacy of jaw thrust device in the upper airway obstruction. Methods Thirty-five ASA Ⅰ or Ⅱ patients aged 18-64 yr with body mass index < 30 kg/m~2 undergoing elective surgery under general anesthesia were included in this study. The anesthesia face mask was placed and held tightly by 4 straps of JTD and connected to the anesthesia machine. Anesthesia was induced with midazolam, propefol, fentanyl and atracurium. When muscle relaxation was achieved, tracheal intubation was not performed. The airway obstruction was assessed by airway peak pressure and stridor score (breathing sounds detected by auscultation over the trachea). And then tracheal intubation was performed, and the patients were mechanically ventilated. Results There was no significant difference in airway pressure and stridor scores between JTD and jaw thrust maneuver. Conclusion JTD can effectively lift the jaw and improve the upper airway obstruction.
