Abstract
Aim and Objective: We compared ultrasound guided single injection thoracic paravertebral block, and preemptive local infiltration at the site of surgical incision as regard postoper-ative pain, decreasiing analgesic requirements, and prolonging the time to first request of analgesia. Also the feasibility of ultrasound in measuruing the depth of thoracic paravertebral space in children undergoing renal surgery.
Material and Methods: 50 patients (2 to 10 years) sched-uled to undergo open renal surgery were randomly assigned into one of two groups; one received ultrasound guided single injection thoracic paravertebral block with measuring the depth of thoracic paravertebral space, after induction of general anesthesia (group PVB), the other group received local infil-tration of skin, subcutaneous tissue, and muscles after induction of general anesthesia and preemptively before surgical incision, (group SII). Postoperative pain scores, time to first reguest of postoperative analgesia and total number of resque doses of postoperative analgesics, were assessed.
Results: The current study demonstrated that ultrasound guided single injection thoracic paravertebral block was superior to the preemptive surgical incision infiltration in children undergoing open renal surgery, as it showed lower CHEOPS and OPS scores, less need of postoperative rescue analgesia and longer time to first request. Depth of thoracic paravertebral space can be measured using ultrasound visual-ization, mean depth in cm was significantly correlated to age of patients included in the PVB group.
