Effects of diaphragm electrical stimulation in treating respiratory dysfunction on mechanical ventilation after intracerebral hemorrhage: A single-center retrospective study

Abstract

Intracerebral hemorrhage (ICH) is a major cause of death and disability worldwide. The benefits of electrical stimulation in the treatment of respiratory dysfunction in patients on mechanical ventilation is unknown. Nevertheless, there is a dearth of evidence-based medical research concerning its clinical efficacy. From January 2019 to January 2023, every enrolled patients experienced respiratory dysfunction after ICH while being supported by mechanical ventilation. A total of 205 eligible patients were enrolled and then allocated into 2 groups: control group and observation group. 133 patients was selected and administered standard treatment as control group. Based on conventional treatment, other 72 patients were administered diaphragm electrical stimulation (DES) treatment. We examined information from current medical records, encompassing all initial data and predictive follow-up data, such as the weaning success rate, occurrence of ventilator-associated pneumonia (VAP), duration of stay in the intensive care unit (ICU) and hospital, expenses related to hospitalization, and mortality within 30 days. The baseline clinical data of the 2 groups did not exhibit any statistically significant disparities (all P > .05). The rate of successful weaning showed a significant increase in the DES group when compared to the control group (P = .025). In patients with respiratory dysfunction due to ICH, treatment with DES resulted in a significant reduction in the duration of invasive ventilation (9.8 ± 2.1 vs 11.2 ± 2.6, P < .01) and total ventilation time (9.8 ± 2.1 vs 11.2 ± 2.6, P < .01). It also led to a decrease in the length of stay in the ICU (15.67 ± 3.76 vs 17.53 ± 4.28, P = .002) and hospitalization cost (11500 vs 13600, P = .001). Additionally, DES treatment resulted in a lower incidence of VAP (73.61% vs 86.46%, P = .022) and improved 30-day mortality (P < .05), without any significant adverse effects. The findings of this research indicate that DESs have a positive impact on enhancing the rate of successful weaning and reducing the incidence of VAP. It decreases the duration of invasive ventilation and total ventilation time while also improving the mortality rate within 30 days. This therapy could offer a fresh alternative for respiratory impairment in patients undergoing mechanical ventilation.
