目的比较小儿全麻术后入麻醉苏醒室(post anesthesia care unit,PACU)经口与经鼻吸氧效果及舒适度。方法 2009年4-5月,将符合纳入标准的100例患儿随机分为两组(n=50)。A组为入PACU时先经口吸氧5min,再经鼻吸氧5min;B组为入PACU时先经鼻吸氧5min,再经口吸氧5min;分别观察吸氧前后的呼吸、心率、脉搏氧饱和度(SpO2)、镇静评分(Ramsay评分)、舒适度的改变。结果两组经口和经鼻吸氧后的SpO2和舒适度比较,两种吸氧方式吸氧5min后均能够有效改善患儿的SpO2(P<0.05);经鼻吸氧比经口吸氧能够更好的改善患儿的SpO2(P<0.05);经口吸氧的舒适度优于经鼻吸氧(P<0.01)。结论患儿不能耐受经鼻吸氧时,可考虑经口吸氧,以改善患儿的氧饱和度和吸氧的舒适度;患儿处于缺氧状态,优先考虑经鼻吸氧能更好的改善患儿的SpO2。
Objective To compare the efficacy and comfort of oral and nasal oxygen inhalation in post-anesthesia care unit (PACU) after pediatric general anesthesia. Methods From April to May 2009, 100 children who met the inclusion criteria were randomly divided into two groups (n = 50). In group A, the rats were orally inhaled for 5 min and then subjected to nasal oxygenation for 5 min after entering the PACU. Group B received nasal oxygenation for 5 min and then orally inhaled for 5 min before entering the PACU. Respiratory rate, heart rate, Pulse oxygen saturation (SpO2), sedation score (Ramsay score), comfort changes. Results SpO2 and comfort after oral and nasal oxygen inhalation were compared between the two groups. Both of the two oxygen inhalation modes were able to effectively improve SpO2 (P <0.05) (P <0.05). Oral oxygen inhalation was superior to nasal oxygen inhalation (P <0.01). Conclusion Children can not tolerate nasal oxygen, Oral oxygen can be considered to improve children’s oxygen saturation and oxygen comfort; children in anoxic, priority nasal oxygen better The improvement of children’s SpO2.
