Key result
High-flow nasal cannula significantly reduced lung atelectasis compared to a standard oxygen face mask following major upper abdominal surgeries (P=0.029).
Why the study?
Postoperative pulmonary complications are a challenge following major surgeries, and whether high-flow nasal cannula after extubation reduces these complications compared to a simple face mask needed assessment.
Does high-flow nasal cannula reduce postoperative pulmonary complications in adult patients following major elective upper abdominal surgeries?

Does high-flow nasal cannula reduce postoperative pulmonary complications in adult patients following major elective upper abdominal surgeries?
p-value: p=0.029
HFNC is more effective than a simple oxygen face mask in reducing lung atelectasis and shortening ICU and hospital stays after major upper abdominal surgeries.
Supports HFNC over face mask after major upper abdominal surgery; extends evidence for postoperative respiratory support in this population.
Background Postoperative pulmonary complications (PPCs) are a challenge for anesthesiologists, especially following major surgeries. Using a high-flow nasal cannula (HFNC) postoperatively may decrease this challenge.Purpose The study aimed to assess the clinical effect of HFNC after extubation compared with simple face mask oxygen following major elective upper abdominal surgeries regarding PPCs, the need to escalate the respiratory support, days of intensive care unit stay, and days of hospital stay.Methods Eighty adult patients were randomly assigned to two groups (each with 40 patients): group I received HFNC, while group II received a standard oxygen face mask. Five days later, postoperative pulmonary problems were evaluated.Results There was statistically significantly less lung atelectasis in the HFNC group than in the face mask group. The p-value was 0.029. There was no statistically significant difference concerning the need to escalate the respiratory support. The length of hospital and ICU stay days for the HFNC group was statistically significantly lower than for the face mask group.Conclusion HFNC is more efficient than a simple oxygen face mask in lowering lung atelectasis following major upper abdominal procedures, improving oxygenation with decreasing respiratory rate and reducing ICU and hospital days of stay.

Soliman et al. (2022) conducted an RCT in Postoperative pulmonary complications after major elective upper abdominal surgeries (n=80). High-flow nasal cannula (HFNC) vs. Standard oxygen face mask was evaluated on Lung atelectasis (p=0.029). High-flow nasal cannula significantly reduced lung atelectasis compared to a standard oxygen face mask following major upper abdominal surgeries (P=0.029).
