Objective To systematically review literature on the influencing factors related to adolescent sub-health problems. Methods We electronically searched the following four databases including CBM, VIP, CNKI and WanFang Data to collect Chinese literature on adolescent sub-health status and problems in China published before May 2012. Two reviewers independently screened literature, extracted data, and cross checked records. Then qualitative analysis was applied. Results According to the inclusion and exclusion criteria, 41 cross-sectional studies were included. The results of qualitative analysis showed that the influencing factors of adolescent sub-health could be classified into four categories including social factors, family factors, school factors, and interpersonal relationships. The main ones were social support, employment pressure, family economic conditions, learning burden, unhealthy habits, etc. Conclusions There are many influencing factors of adolescent sub-health with interaction. Due to the limitation of the included studies, more prospective cohort studies are needed to provide high quality evidence.
【摘要】 目的 比较喉罩和气管内插管吸入七氟烷全麻用于小儿无痛苦纤支镜检查的麻醉效果、苏醒时间、苏醒质量。 方法 将2008年3月-2009年3月40例行纤支镜检查的患儿随机分为喉罩组（L组，21例）和气管内插管组（T组，19例）。两组均采用逐渐诱导法吸入七氟烷，静脉给予芬太尼1 μg/kg；L组置入喉罩，T组气管插管后控制呼吸。手术中，两组均吸入2%～5%七氟烷维持麻醉。分别记录麻醉前（T0）、麻醉后纤支镜进入前（T1）、进镜至咽部（T2）、声门部（T3）、气管内（T4）及第15 min（T5）时的血压（BP）、心率（HR）、MAP和动脉血氧饱和度（SPO2）。观察纤支镜检查期间有无呛咳、气道痉挛或体动；记录停药至拔管的时间，苏醒后是否再入睡及麻醉满意度。 结果 两组HR在T1、T3、T4时升高，与T0时比较，有统计学意义（Plt;0.05）；其中HR在T1时T组高于L组，组间比较有统计学意义（Plt;0.05）；MAP在T1、T2、T3、T4时，T组低于L组，组间比较有统计学意义（Plt;0.05）。两组患儿镜检期间均无呛咳、气道痉挛或体动；L组苏醒时间短于T组（Plt;0.05），苏醒后再入睡率低于T组（Plt;0.05），麻醉满意度高于T组（Plt;0.05）。 结论 喉罩吸入七氟烷全麻用于小儿无痛苦纤支镜检查，能保证稳定的血流动力学状态，苏醒快速，效果满意。【Abstract】 Objective To assess the feasibility and safety of Laryngeal mask combined with sevoflurane in painless fiberoptic bronchoscopy anesthesia in children. Methods Forty children from March 2008 to March 2009 were randomized divided into laryngeal mask airway group (group L) and endotracheal intubation group (group T). Anaesthesia was induced and maintenanced with 2%-5% sevoflurane and fentanyl 1 μg/kg. The blood pressure (BR), heart rate (HR) and oxygen saturation by pulse oximeter (SPO2)were recorded before anaesthesia (T0), immediately after anaesthesia induction (T1), when FOB at the level of pharynx(T2), vocal cords (T3), trachea (T4) and in 15 min of the FOB (T5). Extubation time, recovery quality and anesthesia effects were also analyzed. Results Compared with T0, there were significant increases in HR at T1、T3 and T4 (Plt;0.05), and HR was significantly higher in the group T than that in the group L at T1 (Plt;0.05). MAP was significantly lower in group T than that in group L at T1、T2、T3 and T4, respectively(Plt;0.05). Recovery time was significantly shorter in group L than that in group T. Incidence of sleep after recovery was lower in group L than that in group T. Anesthesia satisfaction was higher in the group L than that in the group T. Conclusions Laryngeal mask combined with Sevoflurane provide satisfactory anesthesia for painless fiberoptic bronchoscopy in children.
