Ultrasound Guided Erector Spinae Block for Postoperative Analgesia in Thoracotomy Patients

2018-11-27 21:42:15 | BioPortfolio


aim of this study is to assess and compare between the efficacy of the new U/S guided erector spinae plane block (ESP) and the conventional methods of systemic analgesics in adult patients scheduled for elective thoracotomy surgery.


Thoracotomy is considered the most painful of surgical procedures and providing effective analgesia is the onus for all anesthetists. Ineffective pain relief impedes deep breathing, coughing, and remobilization culminating in atelectasis and pneumonia.The erector spinae plane (ESP) block is a newly-described technique for treating thoracic pain, and has several advantages that make it an attractive alternative to these more invasive procedures.Ultrasound guided erector spinae (ESP) block is a regional anesthesia technique, recently described by (Forero; et al.) for use in thoracic neuropathic pain. ESP block is reported to lead to analgesic effect on somatic and visceral pain by effecting the ventral rami and rami communicantes that include sympathetic nerve fibers, as LA spreads through the paravertebral space . When performed bilaterally it has been reported to be as effective as thoracic epidural analgesia.ESP block leads to effective postoperative analgesia when performed at T 4-5 level for breast and thoracic surgery. The ESP block , will be performed as follow:The patient will be placed in a sitting position and the ultrasound probe will be placed in a longitudinal orientation 3 cm lateral to the T5 spinous process. Three muscles were identified superficial to the hyperechoic transverse process shadow as follows: trapezius, rhomboid major, and erector spinae . the needle will be inserted in a cephalad-to-caudad direction until the tip lay deep to erector spinae muscles, as evidenced by visible linear spread of fluid beneath muscle upon injection . A total of 20 mL of 0.25% bupivacaine will be injected here.

Medical and Biotech [MESH] Definitions

A nonsteroidal anti-inflammatory agent with potent analgesic and antiarthritic properties. It has been shown to be effective in the treatment of OSTEOARTHRITIS; RHEUMATOID ARTHRITIS; ankylosing SPONDYLITIS; and in the alleviation of postoperative pain (PAIN, POSTOPERATIVE).

Pain during the period after surgery.

A narcotic analgesic that can be used for the relief of most types of moderate to severe pain, including postoperative pain and the pain of labor. Prolonged use may lead to dependence of the morphine type; withdrawal symptoms appear more rapidly than with morphine and are of shorter duration.

Abdominal symptoms after removal of the GALLBLADDER. The common postoperative symptoms are often the same as those present before the operation, such as COLIC, bloating, NAUSEA, and VOMITING. There is pain on palpation of the right upper quadrant and sometimes JAUNDICE. The term is often used, inaccurately, to describe such postoperative symptoms not due to gallbladder removal.

Interruption of sympathetic pathways, by local injection of an anesthetic agent, at any of four levels: peripheral nerve block, sympathetic ganglion block, extradural block, and subarachnoid block.
