|
Objectives of Study: |
This study mainly explored the effectiveness of CPAP-assisted patients in spontaneous breathing compared with the conventional spontaneous breathing mode and the hand-controlled mask ventilation mode after giving muscle relaxants. This study also needs to explore the incidence of reflux during induction in the three modes |

药物成份或治疗方案详述: |
经本院医学伦理委员会批准,按照入组标准筛选入组患者,患者签署知情同意书后,将 90 例拟行插管全麻手术的患者纳入本次研究。通过随机数表法分为三组,每组30例,分别为自主呼吸去氮组(A组)、诱导后正压通气去氮组(B组)和CPAP辅助通气去氮组(C组),由双人完成麻醉诱导并记录以下相关指标。 所有患者术前禁食 8-12 h,均不给术前用药。 进入手术室后,连接监护仪监测生命体征,开放静脉通路,在局部麻醉下行桡动脉穿刺置管。在呼吸空气条件下记录血氧饱和度(SpO2)并采集动脉血行动脉血气分析。在麻醉机以纯氧10L/min预充管道>3min,给氧去氮:A 组患者使用紧闭面罩,嘱患者做自主呼吸观察呼吸机呼出段氧浓度达到90%后,记录相应时间,从最后一次通气结束开始计时,4min内完成快速序贯诱导(静注丙泊酚2mg/kg,瑞芬太尼1μg/kg,罗库溴铵0.6mg/kg,插管前给予利多卡因1.5 mg/kg)以可视喉镜行气管插管术;B组患者则在快速实施手控正压通气,吸气压力不超过15cmH20,潮气量控制在8-10ml/kg,频率为12次/min诱导后,观察呼吸机呼出段氧浓度达到90%所需时间,最后一次通气结束开始计时,4min内完成可视喉镜下气管插管;C组患者,在诱导前使用紧闭面罩,将麻醉呼吸机调至CPAP模式,调节氧流量为10L/min,PSV (8cmH20)+PEEP(2cmH20)实施辅助通气,呼出气氧浓度达到90%所需时间,从最后一次通气结束开始计时,4min内完成可视喉镜下气管插。记录4min内氧饱和度下降到95%、93%及90%的时间,若4min内氧饱和度下降到90%以下,立即连接呼吸管路给予通气,并记录为失败案例各组均在插管时对管路以50%进行预充>3min,各组患者均在确保气管导管在气管内后,保持气管开放至第4分钟时连接呼吸机进行机械通气,并在此时采集动脉血气进行分析,设定潮气量为8ml/kg(理想体重),呼吸频率10次/分钟,新鲜气体流量2L/min,吸氧浓度50%,记录前三次机械通气呼末氧气浓度,并计算平均值作为无通气4分钟后肺泡气氧浓度。气管插管时观察有无反流情况发生(咽喉壁集聚胃液)。统计方法:对诱导时呼气氧浓度达标时间、无通气4分钟后肺泡气氧浓度和插管后血气分析中氧分压将采用方差检验比较组间差异,而各组间反流发生情况将采用卡方检验比较组间差异。 |

Description for medicine or protocol of treatment in detail: |
After being approved by the Medical Ethics Committee of our hospital, the enrolled patients were screened according to the enrollment criteria. After the patients signed the informed consent, 90 patients undergoing intubation general anesthesia were included in this study. Random number table method was divided into three groups, 30 cases in each group, namely spontaneous breathing denitrification group (group A), post-induction positive pressure ventilation denitrification group (group B) and CPAP assisted ventilation denitrification group (group C) , The two persons complete the induction of anesthesia and record the following relevant indicators. All patients fasted for 8-12 h before surgery, and no medication was given before surgery. After entering the operating room, connect the monitor to monitor vital signs, open the venous access, and place the catheter under the radial artery puncture under local anesthesia. Record blood oxygen saturation (SpO2) under breathing air and collect arterial blood for arterial blood gas analysis. In the anesthesia machine, pre-fill the pipeline with pure oxygen 10L / min for> 3min, and supply oxygen to denitrogenation: the patients in group A use a closed mask and instruct the patients to do spontaneous breathing to observe that the oxygen concentration in the exhalation section of the ventilator reaches 90%, and record the corresponding time from the last Start timing at the end of one ventilation and complete rapid sequential induction within 4 minutes (intravenous propofol 2mg / kg, remifentanil 1μg / kg, rocuronium 0.6mg / kg, and lidocaine 1.5 mg / before intubation kg) endotracheal intubation with visual laryngoscope; patients in group B are rapidly performing manual controlled positive pressure ventilation, the inspiratory pressure does not exceed 15cmH20, the tidal volume is controlled at 8-10ml / kg, and the frequency is 12 times / min induction After that, observe the time required for the oxygen concentration in the exhalation section of the ventilator to reach 90%, and start timing the end of the last ventilation, complete the endotracheal intubation under the visual laryngoscope within 4 minutes; patients in group C use a closed mask before induction to breathe anesthesia The machine is adjusted to CPAP mode, the oxygen flow is adjusted to 10L / min, PSV (8cmH20) + PEEP (2cmH20) to implement auxiliary ventilation, the time required for the exhaled oxygen concentration to reach 90%, the timing starts from the end of the last ventilation, and can be completed within 4 minutes Intubate under the laryngoscope. Record the time when the oxygen saturation drops to 95%, 93% and 90% within 4 minutes. If the oxygen saturation drops below 90% within 4 minutes, immediately connect the breathing circuit to provide ventilation and record as a failure case.Each group pre-filled the tubing with 50% during intubation for> 3 minutes. After ensuring that the tracheal tube was in the trachea, the patients in each group were connected to the ventilator for mechanical ventilation when the trachea was open until the 4th minute. Collect arterial blood gas for analysis, set the tidal volume to 8ml / kg (ideal body weight), breathing rate 10 times / min, fresh gas flow rate 2L / min, oxygen concentration 50%, record the oxygen concentration at the end of the first three mechanical ventilation, And calculate the average value as the alveolar oxygen concentration after 4 minutes without ventilation. Observe if reflux occurs during tracheal intubation (gastric fluid accumulates in the throat wall). Statistical method: the time of reaching the expiratory oxygen concentration at the time of induction, the alveolar oxygen concentration after 4 minutes without ventilation, and the oxygen partial pressure in the blood gas analysis after intubation will be compared with the difference between groups, and the occurrence of reflux between groups Chi-square test was used to compare the differences between groups. |
