Comparison of HFNC and COT to Diaphragm Function of Post-upper Abdominal Surgery Patients

Not Applicable
Completed
Conditions
Post Abdominal Surgery
Interventions
Procedure: HFNC; COT
Registration Number
NCT04059614
Lead Sponsor
Indonesia University
Brief Summary

This study aims to compare diaphragm thickness, air lung distribution, and several clinical and laboratory parameters on post abdominal surgery patients with conventional oxygen therapy vs high-flow nasal cannula

Detailed Description

"Approval from Ethical Committee of Faculty of Medicine Universitas Indonesia was acquired prior conducting the study. Subjects were recruited using consecutive sampling method. Subjects underwent upper-abdominal surgery were screened. Eligible and consented subjects were randomized into intervention group (high-flow nasal cannula) and control group (conventional oxygen therapy). Subject and operation characteristics were recorded prior to intervention.

Clinical parameters (vital signs, Borg Score, ICON) were recorded in 10 specific times. diaphragm thickness data using abdominal ultrasonography (USG) and air lung distribution data using Electrical Impedance Tomography were collected in 7 specific times while lactate and blood gas analysis were done 4 times. "
