JRCT ID: jRCTs072210047

Registered date:28/07/2021

Basic Information

• Recruitment status: Recruiting
• Health condition(s) or Problem(s) studied: Biliary disease
• Date of first enrollment: 17/05/2022
• Target sample size: 118
• Study type: Interventional
• Intervention(s): NHF intervention

Outcome(s)

• Primary Outcome: total dose of pethidine, an analgesic used in combination

Secondary Outcome

1) Occurrence rate of marked hypercapnia showing a maximum percutaneous carbon dioxide concentration of 60 mmHg or more (corresponding to PaCO2> 55 mmHg) during intravenous anesthesia.
2) Area under the curve (AUC) of percutaneous carbon dioxide concentration per unit time during intravenous anesthesia
3) Duration of moderate hypercapnia showing a maximum percutaneous carbon dioxide concentration of 50 mmHg or more (equivalent to PaCO2> 45 mmHg) during intravenous anesthesia
4) Incidence of hypoxemia with percutaneous oxygen saturation of 90% or less during intravenous anesthesia
5) Respiratory rate using Radical 7
6) Respiratory rate from changes in impedance of ECG electrodes
7) Total dose of sedative (Dexmedetomidine and Midazolam), dose per anesthesia time
8) Sedation level using SEDLINE
9) Ramsay scale, which is an objective evaluation
