Comparison of Analgesic and Sedative Effects of Esmketamine and Remifentanil Combined With Propofol Respectively in Septic Shock Patients With Invasive Mechanical Ventilation

Septic shock patients with invasive mechanical ventilation who were randomly enrolled in ICU were divided into esketamine group (test group) and remifentanil group (control group) according to the ratio of 1:1. The dose of vasopressor, the time of mechanical ventilation, the incidence of intestinal dysfunction and the dose of propofol were compared between the two groups. Through statistical analysis, it was determined whether esketamine combined with propofol could improve the prognosis of septic shock patients with invasive mechanical ventilation and reduce the adverse reactions of analgesic and sedative drugs compared with remifentanil combined with propofol.

The purpose of this study is to determine whether esketamine combined with propofol can improve the prognosis and reduce the adverse effects of analgesic and sedative drugs in septic shock patients undergoing invasive mechanical ventilation compared with remifentanil combined with propofol. Study methods: septic shock patients with invasive mechanical ventilation in ICU were randomly divided into esketamine group (test group) and remifentanil group (control group) according to the ratio of 1:1. 120 patients are expected to be enrolled. The dose of vasopressor, the time of mechanical ventilation, the incidence of intestinal dysfunction and the dose of propofol were compared between the two groups. Through statistical analysis, it was determined whether esketamine combined with propofol could improve the prognosis of septic shock patients with invasive mechanical ventilation and reduce the adverse reactions of analgesic and sedative drugs compared with remifentanil combined with propofol. From January 1, 2023 to January 1, 2024, the clinical study of the patients (60 cases) enrolled in the first phase was completed as expected in the study protocol. Stage objective: to count the relevant detection indicators of the two groups of patients, analyze and compare whether there is a difference between the primary endpoint and the secondary observation endpoint, and write a research paper and a mid-term summary. From January 1, 2024 to January 1, 2025, the clinical study of patients (60 cases) enrolled in the second phase was completed according to the research protocol. Stage objective: to count the relevant detection indicators of the two groups of patients, analyze and compare whether there is a difference between the primary endpoint and the secondary observation endpoint, and write a research paper and a conclusion report. Publication form of research results: 1-2 academic papers published in domestic or international journals.
