Analysis data of the effect of oxygen inhalation with circular arch head fixation in infants after lacrimal passage recanalization

To explore the clinical application of the ring arch head fixation method for oxygen inhalation after general anesthesia for nasolacrimal passage recanalization in ophthalmic newborns. Method: Fifty newborns who underwent nasolacrimal duct recanalization surgery were randomly assigned to either a control group or an observation group, with 25 cases in each. The control group received routine disposable nasal cannula oxygen inhalation after surgery; The observation group adopted the double nasal cannula ring arch head fixation method for oxygen inhalation. All patients were given oxygen therapy for 2 hours after surgery, and their blood oxygen saturation was monitored to observe the condition of extubation and the occurrence of MARSI.
