测量指标:

Outcomes:

指标中文名:

拔除喉罩后30 min的改良Aldrete苏醒评分,术后相关并发症,术前后一天恢复质量评分(QoR-15评分量表)

指标类型:

次要指标

Outcome:

Modified Aldrete score at 30 minutes after removal of the laryngeal mask airway, postoperative complications, and QoR-15 scale

Type:

Secondary indicator

测量时间点:

术前一天,术后拔除喉罩后30min,术后一天

测量方法:

填写QoR-15评分量表及改良Aldrete苏醒评分表,询问患者

Measure time point of outcome:

Preoperative day 1, 30 minutes after removal of the laryngeal mask airway, and postoperative day 1.

Measure method:

Complete the QoR-15 scoring scale and the Modified Aldrete Score, and assess the patient.

指标中文名:

比较两组间喉罩置入耗时,首次置入成功率,置入次数,手指引导置入率

指标类型:

次要指标

Outcome:

Laryngeal mask airway insertion time, first-attempt success rate, number of insertion attempts, finger-guided insertion rate were compared between the two groups

Type:

Secondary indicator

测量时间点:

喉罩置入成功时

测量方法:

通过时钟及人为记录

Measure time point of outcome:

at the successful LMA insertion

Measure method:

through timekeeping and human documentation

指标中文名:

比较两组术中的气道峰压,呼吸末二氧化碳分压,是否出现喉罩移位漏气

指标类型:

次要指标

Outcome:

Peak airway pressure, end-tidal carbon dioxide partial pressure, and whether laryngeal mask airway displacement with leakage has occurred were compared between the two groups

Type:

Secondary indicator

测量时间点:

喉罩置入成功时、气腹时、气腹30分钟时及手术结束时

测量方法:

人为记录监护仪数据及观察喉罩是否移位漏气

Measure time point of outcome:

successful LMA insertion,at the establishment of pneumoperitoneum,30 min after pneumoperitoneum,end

Measure method:

Monitor data was recorded artificially and observe if the laryngeal mask airway has shifted or leaked.

指标中文名:

口咽部漏气压

指标类型:

主要指标

Outcome:

oropharyngeal leak pressure

Type:

Primary indicator

测量时间点:

喉罩置入成功时、气腹时、气腹30分钟时及手术结束时

测量方法:

在手动通气模式下,将APL阀调至40 cmH2O,氧流量调至3 L/min,当口咽部出现漏气时,记录此时的气道压力作为OLP,如高于40 cmH2O仍无漏气,则记录密封压为40 cmH2O。

Measure time point of outcome:

successful LMA insertion,at the establishment of pneumoperitoneum,30 min after pneumoperitoneum,end

Measure method:

In manual ventilation mode, set the APL valve to 40 cmH?O and adjust the oxygen flow to 3?L/min. When air leakage occurs at the oropharynx, record the airway pressure at that moment as the OLP. If no leakage occurs even when the pressure exceeds 40?cmH?O, then record the seal pressure as 40?cmH?O.
