Overview
The objective of this clinical study is to evaluate the initial efficacy and safety of LIPUS as an adjunct to standard therapy in patients with shock. The investigators will invite patients to participate in a proof-of-concept study investigating the efficacy of neck ultrasound stimulation to enhance anti-shock treatment, involving brief exposure to low-intensity pulsed ultrasound. This study examines whether LIPUS can enhance blood pressure in patients with shock, improve the efficacy of antihypotensive treatment, and reduce the dosage and duration of vasoactive drugs during active pharmacological therapy. By applying LIPUS as an adjunct to conventional treatment in clinical cases of shock, we aim to determine the clinical value of LIPUS and establish a theoretical foundation for developing innovative new therapies for shock.
Interventions
- Device Low-intensity pulsed ultrasound
During periods of stable blood pressure, administer cervical ultrasound stimulation (3-minute stimulation followed by a 2-minute interval, repeated cyclically; total stimulation duration not exceeding 60 minutes).
Primary outcome measures
- The proportion of patients whose SBP exceeded 90 mmHg and remained stable for at least 5 minutes within 5 minutes of receiving LIPUS treatment or control group treatment [Time frame: From the start of treatment to 60 minutes after the intervention]
Secondary outcome measures (9)
- The proportion of cases where blood pressure increased by more than 10,15,or 20 mmHg above pre-treatment levels and remained elevated for at least 5 minutes, along with the duration of elevation. [Time frame: From the start of treatment to 60 minutes after the intervention]
- The total duration from achieving a blood pressure of ≥90 mmHg after treatment until it stabilizes and subsequently drops back to ≤90 mmHg. [Time frame: From the start of treatment to 60 minutes after the intervention]
- Time from initiation of LIPUS therapy to patient's SBP exceeding 90 mmHg [Time frame: From the start of treatment to 60 minutes after the intervention]
- Shock Index (SI) Changes [Time frame: Before treatment and 60 minutes after treatment]
- Heart Rate Variability (HRV) Changes [Time frame: Before treatment and 60 minutes after treatment]
- Drug dosages from the initiation of LIPUS therapy until the patient's SBP reaches the effective target [Time frame: From the start of treatment to 60 minutes after the intervention]
- mRS scores for patients in the follow-up control group and experimental group [Time frame: 3 months]
- Length of Stay in Intensive Care Unit (ICU) [Time frame: 3 months]
- Total hospitalization costs [Time frame: 3 months]
