Abstract
Thoracic paravertebral block have been successfully used to provide
analgesia for multiple thoracic and abdominal procedures in both children
and adults.
Several different techniques exist for TPVB; the classical technique, the
use of nerve stimulator and ultrasound guidance Complications of thoracic
paravertebral block include inadvertent needle penetration of adjacent
structures, local anesthetic toxicity, complications due to distribution of
local anesthetic and failure technique. Peripheral application of local
anesthetics can be a useful adjunct in the treatment of acute postoperative
pain. Surgical wound infiltration for relief of post thoracotomy pain has
been shown to improve forced vital capacity and to have morphinesparing
effect. Local anesthetics interfere with impulse generation and
propagation by blocking membrane permeability to sodium. Local
anesthetic toxicity: allergy, neurotoxicity, cardio toxicity and CNS
toxicity.
