[Application of external diaphragm pacemaker combination with high-flow nasal cannula in offline patients with postoperative severe cerebral hemorrhage].

ABSTRACT

Objective: To investigate the offline clinical effect of external diaphragm pacemaker (EDP) combination with High-flow nasal cannula oxygen therapy in postoperative severe cerebral hemorrhage patients. Methods: A total of 123 severe postoperative severe cerebral hemorrhage patients with tracheotomy and mechanical ventilation (MV) were selected, who were admitted in NICU of PLA Rocket Force Characteristic Medical Center from October 2016 to December 2019. These patients were randomly divided into the High-flow nasal cannula (HFNC) group (n=63) and HFNC+EDP group (n=60). In the HFNC group, the HFNC was given to the patients who were off ventilator. The HFNC+EDP group was added on the basis of treatment in the HFNC group, once a day and 30 minutes each time. Results: Compared to the HFNC group, the oxygenation index (OI) of the HFNC+EDP group was higher in the next 1, 12, 24 and 48 hour [(209±15) mmHg vs (218±18) mmHg, (215±14) mmHg vs (222±17) mmHg, (223±13) mmHg vs (235±15) mmHg, (236±7) mmHg vs (257±12) mmHg,P<0.05]. The offline time was shorter [(13±3) d vs (12±3) d,P<0.05]. The excursion of diaphragm was higher [(1.94±0.08) cm vs (2.91±0.11) cm,P<0.05]. The length of stay in NICU was shorter [(33±14) d vs (28±9) d,P<0.05]. The Glasgow Coma Scale (GCS) was higher when being discharged from the NICU (5.9±2.1 vs 7.8±0.4, P<0.05) and the hospital (9.9±2.1 vs 11.0±2.0, P<0.05). Conclusions: EDP combination with HFNC can increase the excursion of diaphragm, shorten the offline time and length of stay in the NICU, thereby enhancing the early recovery and improving the prognosis.
