Abstract:
Objective To evaluate the efficacy of manually controlled jet ventilation with Manujet Ⅲ apparatus (VBM Co, Germany) for removal of airway foreign body in children. Methods One hundred and twenty ASA Ⅰ or Ⅱ children aged 10 months-12 yr, weighing 8-35 kg undergoing removal of airway foreign body were randomly divided into 3 groups (n=40 each) : group Ⅰ spontaneous respiration (SR) ; group Ⅱ intermittentpositive pressure ventilation through the short side tube of the rigid bronchoscope (IPPV) and group Ⅲ manually controlled jet ventilation with Manujet Ⅲ (JV). Anesthesia was induced with methylprednisolone 2 mg/kg, propofol 2 mg/kg and γ-OH 70 mg/kg in group SR (Ⅰ) and with methylprednisolone 2 mg/kg, propofol 4-5 mg/kg, fentanyl 1.5 μg/kg and succinylcholine 2 mg/kg in group IPPV and JV (Ⅱ,Ⅲ). The bronchescope insertion condition, the occurrence of hypoxia during and after operation, body movement during operation, the rate of successful removal of the foreign body, the duration of operation, anesthesia emergence time and perioperative side effects were recorded. Resulls The rate of good bronchescope insertion condition and successful removal of airway foreign body were significantly higher, the rate of hypoxia during and after operation, body movement, breath holding and restlessness were significantly lower and duration of operation and anesthesia emergence time were significantly shorter in group IPPV and JV than in group SR (P<0.05). The rate of intraoperative hypoxia was significantly lower in group JV than in group IPPV (P<0.05). Conclusion Jet ventilation with Manujet Ⅲ can reduce the occurrence of hypoxia during removal of airway foreign body in children and does not interfere with the operation.
