Application of Sevoflurane Inhalation Anesthesia by Mask in Children Undertaking Lacrimal Passage Probing

Objective To observe the clinical effect of sevoflurane inhalation anesthesia by mask in children undertaking lacrimal passage probing. Methods Forty congenital dacryocystitis cases treated with lacrimal passage probing,aged from 3 months to 12 months,were randomly divided into sevoflurane inhalation anaesthesia group(sevoflurane group)and ketamine basal anesthesia group(ketamine group). Sevoflurane inhalation by mask or ketamine intramuscular injection were used for induction and maintenance of anesthesia. The mean arterial pressure(MAP),heart rate(HR),respiratory frequency(R) and pulse oxygen saturation(SpO2) during anesthesia were recorded.The consciousness extinction time,consciousness recovery time and sojourn time in anaesthesia recovery room were recorded. The side-effects during ansesthesia were investigated. Results The MAP gently decreased in sevoflurane group. However,The MAP and HR markedly rised in ketamine group. The consciousness extinction time,consciousness recovery time and sojourn time in anaesthesia recovery room in sevoflurane group were obviously shorter than these time in ketamine group. Less excitation,restlessness and secretion happened in sevoflurane group. Conclusion Sevoflurane inhalation anesthesia by mask can be used for children undertaking lacrimal passage probing.
