Erector Spinea Plane Block Clinical Trial
Official title:
The Effects of Different Positions on the Diffusion and Blockade Effect of Ultrasound-guided Erector Spinae Plane Block
After the completion of exploring the vertical erector spinae plane block, the patient maintains different positions to assess the diffusion of local anesthetic and the effect of the block.
Thirty patients were selected to undergo CT guided puncture localization of pulmonary nodules under local anesthesia, and the patients were divided into groups using a computer-generated random number in a ratio of 1:1:1. To ensure objectivity, a nurse who was not involved in the study prepared a sealed opaque envelope containing grouping information. Randomly divide patients into three groups: supine position group (S group, 10 cases), prone position group (P group, 10 cases), and lateral position group (L group, 10 cases). The patient underwent ultrasound guided ESPB on the puncture side before CT puncture localization. Ultrasound guided ESPB method: Using an ultrasound high-frequency linear array probe (5-13MHz, Sonosite, USA), the probe is placed parallel to the spine on the surface of the transverse process tip of the fifth thoracic vertebrae. Under ultrasound, the transverse process and surface vertical spinal muscles are clearly exposed. Then, a short inclined plane puncture needle is used, and the needle is inserted from the head side using in-plane technology. After the needle tip reaches below the transverse process plane vertical spinal muscles, 2ml of physiological saline is injected using water separation technology to confirm the position of the needle tip, Then inject 30ml of local anesthetic solution (0.375% ropivacaine 25ml+iohexol 5ml). After the block was completed, patients in Group S remained in a supine position; Patients in group L maintained the blocking side above; Patients in Group P maintained a prone position. After 1 hour of block completion, CT scan and puncture localization were performed, followed by 3D reconstruction. Observation and recording of local anesthetic solution: 1. Diffusion range towards the head and tail; 2-way diffusion range of rib gap on one side 3; Diffusion to the paravertebral space; 4. Diffusion into the epidural space. ;
