Erector Spinae Plane Block Improves Organ Dysfunction in Septic Patients With Acute Gastrointestinal Injury

Ultrasound-guided erector spinae plane block is performed at thoracic (T) level 8. An 18F catheter is placed on both sides of the thoracic vertebra deep into the erector spinae, and a bolus of 20 ml of 0.375% ropivacaine is administered bilaterally. Then, a continuous infusion of 20 ml of 0.375% ropivacaine on each side is followed at a rate of 2 ml/h every 12 hours. The intervention ends on day 7 or ceases when the patient is discharged from the ICU, died, or withdrew their consent.
