目的:为了更深入的研究在儿童疝气手术中用喉罩吸入七氟醚的临床治疗效果,和此种方法的安全可靠性。方法:选取2011年2月到10月在我院进行手术治疗的疝气患儿50例,对这些患儿的临床资料进行回顾分析,这些患儿均没有神经系统、体内循环、呼吸类的疾病。为这50例患儿提供麻醉诱导,按照患儿每千克的体重使用2mg的丙泊酚,然后使用喉罩让患儿吸入七氟醚,使用氧气呼吸机,将每分钟的氧气流量控制在2到3L,吸入前30s的浓度为8%,然后将浓度减少到每30s内4%,等患儿的下颌关节松弛后,将喉罩插入,插入喉罩前在气囊上面涂抹2%的利多卡因,手术中每分钟将氧气流量维持在1.5L,吸入浓度为2%的七氟醚。详细观察并严格记录患儿的各项生命指征。结果:这50例患儿在麻醉后治疗效果显著。比较麻醉期间的各个时间点,P>0.05,没有差异统计学意义。有5例患儿在拔除喉罩后患儿的呼吸道不顺畅,使用有氧呼吸机后情况得到好转,没有产生各种并发症。结论:在手术治疗儿童疝气中使用喉罩吸入七氟醚有很好的治疗效果,具有很高的可靠性与安全性。
OBJECTIVE: To investigate in more depth the clinical efficacy of sevoflurane inhalation with laryngeal mask in hernia surgery and the safety and reliability of this method. Methods: Fifty children with hernia undergoing surgical treatment in our hospital from February to October 2011 were retrospectively analyzed. The clinical data of these children were analyzed retrospectively. All of these children had no diseases of the nervous system, circulatory system and respiratory system. Anesthesia was induced in these 50 patients. Propofol was administered at a rate of 2 mg per kilogram of body weight in children and laryngeal mask was used to inhale sevoflurane in children. Oxygen breathing machines were used to control oxygen flow per minute to 2 To 3L, the concentration of the first 30s before inhalation 8%, and then reduce the concentration to 4% every 30s, and other children with mandibular joint relaxation, the laryngeal mask inserted into the laryngeal mask before the application of 2% lidocaine Because of the oxygen flow per minute during surgery to maintain 1.5L, inhalation concentration of 2% sevoflurane. Detailed observation and strict records of children’s life indications. Results: The 50 cases of children in the treatment of significant effect after anesthesia. Comparison of anesthesia at various time points, P> 0.05, no statistically significant difference. In 5 cases, the respiratory tract of the child was not smooth after the laryngeal mask was removed. The situation was improved after using the aerobic ventilator, and no complications were found. CONCLUSIONS: Sevoflurane inhalation of sevoflurane in surgical treatment of hernia in children has good therapeutic effect, with high reliability and safety.
