JAMA: Study on the effect of mechanical moisture intake on the risk of lung complications after surgery in patients with major surgery.

Ideal moisture intake studies are not sufficient for patients undergoing mechanical air intake during large operations.
recently examined the effects of reducing moisture intake during major surgery on reducing lung complications after surgery.
study was conducted in Melbourne, Australia, involving 1,236 patients over the age of 40 who underwent general anaesthetic surgery for more than 2 hours for non-heart, chest and non-transcranial surgery, and patients who randomly received 6 mL/kg of body mass moisture intake (n=614; low tide group) or 10 mL/kg of moisture (n=592; regular moisture group). The main results of the
study were postoperative lung complications, including pneumonia, bronchial spasms, pulmonary failure, pulmonary congestive, respiratory failure, chest fluid build-up, gas chest, or invasive or non-invasive ventilation after uncrafted surgery. The
secondary results were postoperative lung complications, including pulmonary embolism, acute respiratory distress syndrome, systemic inflammatory response syndrome, sepsis, acute kidney injury, wound infection (shallow and deep), ratio of angiopressin needed during surgery, unmuted intensive care unit admission rate, intensive care unit hospitalization time, hospital stay and hospitalization mortality rate.
1,236 patients participated in the study, 1,206 (98.9%) completed the trial, with an average age of 63.5 years, 494 female patients and 681 patients (56.4%) undergoing abdominal surgery.
231 (38%) of the 608 patients in the
hysteresia group had a primary end time, while 232 of the 590 patients in the conventional hysteresia group (39%, variance, -1.3%, risk ratio, 0.97).
there was no significant difference in any secondary results between the two groups.
that patients who needed mechanical air during major surgery failed to reduce the risk of lung complications after surgery.
