About this trial
Dyspnea is common and distressing in patients with acute respiratory failure. In our intensive care unit, some patients receive a cervical erector spinae plane (ESP) block to help relieve dyspnea. This study will observe patients who receive bilateral cervical ESP blocks and measure changes in dyspnea using validated scales at predefined time points over 24 hours. We will also track vital signs, arterial blood gas values, and diaphragm movement on ultrasound.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
ICU admission with acute respiratory failure.
Patient or legally authorized representative provides consent.
Cervical ESP block performed for dyspnea treatment
Disqualifiers
Infection at block site.
Known diaphragm paralysis.
Known allergy to local anesthetics.
Refusal of consent (patient or representative).
Trial population
Consecutive adult patients in the mixed medical-surgical ICU of a tertiary university hospital (Hacettepe University Hospital, Ankara, Türkiye). The ICU manages acute respiratory failure due to pneumonia, COPD/asthma, pulmonary edema, and post-operative causes. Patients who receive a cervical ESP block for dyspnea as are observed for changes over 24 hours.

Trial outcomes
Primary outcomes
1
Change in Dyspnea by Visual Analog Scale (D-VAS)
Patient-reported dyspnea on a 100-mm line (0=no dyspnea, 100=worst imaginable); measured in mm from 0 anchor to the patient's mark.
Time frame
Baseline (pre-block), 30 minutes, 8 hours, 16 hours, and 24 hours after the ESP block.Secondary outcomes
1
Respiratory Distress Observation Scale (RDOS) Score
Observer-rated RDOS (higher scores indicate more severe respiratory distress); standard scoring per instrument.
Time frame
Baseline, 30 minutes, 8 hours, 16 hours, 24 hours post-block.2
Intensive Care Respiratory Distress Observation Scale (IC-RDOS) Score
Observer-rated IC-RDOS (higher scores worse); standard scoring per instrument.
Time frame
Baseline, 30 minutes, 8 hours, 16 hours, 24 hours post-block.3
Diaphragm Excursion Amplitude on Ultrasound
Peak-to-peak diaphragm excursion amplitude measured bilaterally with bedside ultrasound/M-mode.
Time frame
Baseline (pre-block), 30 minutes4
Arterial Blood Gas Parameters: pH, PaO₂, PaCO₂ , SaO₂, HCO₃-
Abstracted from ABGs
Time frame
Baseline (pre-block), 30 minutes, 8 hours, 16 hours, and 24 hours after the ESP block.Locations
