Observation of the intravenous anesthesia compounding with the surface anesthesia by ultrasonic spray for pediatric bronchoscopy / 安徽医科大学学报

ABSTRACT

Objective　To discuss the possibility of ultrasonic superficial spray anesthesia applied to bronchoscopy in children with intratracheal foreign bodies. Methods　50 cases with intratracheal foreign body were divided into two groups surface anesthesia group (S group) and intravenous anesthesia group (Ⅰ group). 2% Lidocain by ultrasonic spraying inhalation for 8～10 min and r-OH 80 mg*kg-1+Ketamine 1 mg.kg-1 intravenous injection were adminstered respectively. Results　In S group perioperative the MAP and HR were stable， the complications were fewer and the SpO2 was >95%，the awaking time was shorter (70.1±15.3) min after operation；In I group the MAP and HR were descendent (P<0.05)， the complications were more and the SpO2 was <95% (P<0.05)， the awaking time was longer(P<0.01). Conclusion　The surface anesthesia is effective.The MAP and HR are stable，the complications are fewer and the awaking time is shorter.
