Interventional thoracic ultrasonography (TUS) includes both diagnostic and therapeutic procedures. Fine-needle aspiration biopsy , Tru-cut Pleural or lung parenchymal biopsy and Cope or Abrams needles pleural biopsies are examples of diagnostic procedures while ultrasound guided thoracentesis, pleural aspiration for pneumothorax, placement of chest tubes, and indwelling catheter insertion, or pleurodesis are common therapeutic procedures.~Thoracic ultrasound guided procedures are safe and tolerable. Pain, pneumothorax, bleeding, infection, and procedure failure are the possible complications of TUS guided procedures. Lidocaine 1% should be infiltrated prior to the procedure, paying particular attention to the skin, periosteum and the pleura as a local anesthesia.~To reduce pain, analgesia should be considered as premedication. Despite the apparent common sense of this approach, there is little established evidence of the effect from these medications.
This study aims to evaluate the efficacy of single dose analgesia in combination with local anesthesia to control pain during Trans Ultrasound guided procedures. It also aims to assess the effect of its use on procedure performance time and rate of complications occurrence compared to local anesthesia alone.
