Abstract:
Objective To evaluate the efficacy of a type of endotracheal tube of extended with terminal swelling and resistance bending pressure for airway management during mechanical ventilation in children in prone position.Methods Sixty pediatric patients with cerebral palsy of both sexes,aged 3-7 yr,weighing 11-23 kg,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,scheduled for elective selective functional posterior rhizotomy,were randomly allocated into 2 groups (n =30 each) using a random number table:endotracheal tube of extended with terminal swelling and resistance bending pressure group (group E) and reinforced tracheal tube group (group C).After induction of anesthesia,the type of endotracheal tube of extended with terminal swelling and resistance bending pressure was inserted in group E,and the reinforced endotracheal tube was inserted in group C.The tidal volume,minute ventilation,dynamic lung compliance,arterial oxygen saturation and end-tidal pressure of carbon dioxide in pressurecontrolled ventilation mode were recorded in the two groups.Tube shedding caused by using of the extended tube was recorded during operation.Blood samples were collected from the femoral artery for blood gas analysis.Results Compared with group C,the tidal volume and minute ventilation were significantly increased (P＜0.05),and no significant change was found in dynamic lung compliance,arterial oxygen saturation and end-tidal pressure of carbon dioxide in group E (P＞0.05).Compared with the value before anesthesia,no significant change was found in pH value,arterial oxygen partial pressure and partial pressure of arterial carbon dioxide at the end of operation in the two groups (P＞0.05).In group C,the extended tube wasused in 3 patients,and among the 3 cases,one patient developed tube shedding which was treated immediately.Conclusion The type of endotracheal tube of extended with terminal swelling and resistance bending pressure provides better efficacy than the reinforced endotracheal tube when used for airway management during mechanical ventilation in children in prone position.
