研究目的:

本研究针对减重术后患者由麻醉复苏室(PACU)转运至病房途中,观察相应体位对低氧血症发生及患者舒适安全性的影响,评估采用床头抬高30°体位在肥胖患者麻醉恢复期对呼吸功能的保护作用,验证其临床有效性及安全性,为该类患者围麻醉期护理管理提供临床研究依据,进一步提高恢复期麻醉质控。  

Objectives of Study:

This study aims to observe the impact of different positions on postoperative hypoxemia and patient comfort during the transfer from the Post-Anesthesia Care Unit (PACU) to the ward for patients who have undergone weight loss surgery. The findings are intended to provide clinical evidence for peri-anesthetic care management in such patients and further enhance the quality control of anesthesia during the recovery period.

测量指标:

Outcomes:

指标中文名:

低氧血症发生率

指标类型:

主要指标

Outcome:

The incidence of hypoxemia

Type:

Primary indicator

测量时间点:

患者离PACU至目标病房转运途中

测量方法:

转运途中主要观察实验组和对照组低氧血症发生率:SpO2<92%持续.>=30秒定义为事件,记录转运途中发生次数。并通过指夹式脉搏血氧仪或转运监护仪导出每分钟SpO2数据,绘制变化曲线。

Measure time point of outcome:

The patient is on their way from PACU to the target ward during transportation.

Measure method:

During transportation, mainly observe the incidence of hypoxemia in the experimental group and the control group: SpO2 < 92% for >=30 seconds is defined as an event, and the number of occurrences during transportation is recorded. Additionally, using a finger pulse oximeter or transport monitor, extract SpO2 data every minute and plot the change curve.

指标中文名:

低氧血症持续时间

指标类型:

主要指标

Outcome:

Hypoxemia duration

Measure time point of outcome:

The patient is on their way from PACU to the target ward during transportation.

Measure method:

Start observing the changes in SpO2 when the patient leaves the PACU. If SpO2 < 92%, begin timing and instruct the patient to perform deep breathing and effective coughing until the patient's SpO2 > 95%. Record the duration of each event and the number of occurrences of hypoxemia.

Immediate SpO2 upon arrival at the ward bed unit: The SpO2 displayed on the monitor when the patient is transferred to the ward bed. The incidence of hypoxemia in the experimental group and the control group is observed: If SpO2 < 92%, oxygen inhalation is immediately administered, and the patient's breathing and oxygen sat
