USG Guided ESP Block in Spinal Surgery

American Society of Anaesthesiologist physical status I-II, aged between 18-65, 40 patients which underwent lumbar spinal surgery will recruited to this study. These subjects will Ultrasound (USG) guided erector spinae block will perform at T10 level (bilaterally) to the all patient under general anaesthesia. 15 ml bupivacaine %0.5 and 5 ml lidocaine %2 will use for USG guided ESP block. 0.1 microgram/kg morphine will apply intravenously and diclofenac Na 75 mg intramuscularly will apply at last 30 minutes of surgery postoperative analgesia to all patients. Postoperative pain assessment will perform with visual analog scale (VAS)

American Society of Anaesthesiologist physical status I-II, aged between 18-65, 40 patients which underwent lumbar spinal surgery will recruited to this study. The patients were randomly allocated into two groups (1:1), via a computer-generated randomization list. Ultrasound (USG) guided erector spinae block will perform at T10 level (bilaterally) to the 20 patients under general anaesthesia in Group E and same volume saline will apply to the ESP block region at T10 level for control group (Group C). Total intravenous anaesthesia (propofol+remifentanil) will perform to the all patients. 15 ml bupivacaine %0.5 and 5 ml lidocaine %2 will use for USG guided ESP block. 0.1 microgram/kg morphine intravenously and diclofenac Na 75 mg intramuscularly will apply for postoperative analgesia to the all patients at last 30 minutes of surgery. Postoperative pain assessment will perform with visual analog scale (VAS). VAS, morphine consumption and complications will record. The rescue analgesic 0.4 mg/kg mepheridine will administer intravenously whenever the patient requested to the analgesic. Diclofenac sodium 75 mg will repeat to the all patients at the 12th of postoperative period, intramuscularly.

15 ml bupivacaine+ 5 ml lidocaine will use for USG guided ESP block under general anaesthesia with Sevuflurane and remifentanil. This block will perform at the T10 level bilaterally after induction of anaesthesia at the prone position. The patients will receive Morphine 0.1 microgram/kg intravenously and diclofenac sodium 75 mg intramuscularly at the last 30th minute of surgery. Postoperative pain assessment will perform with VAS score. The rescue analgesic 0.4 mg/kg meperidine will be apply intravenously whenever the patient requested to the analgesic.

In this group, the same volume saline will apply to the block region. The patients will receive Morphine 0.1 microgram/kg intravenously and diclofenac sodium 75 mg intramuscularly at the last 30th minute of surgery. Postoperative pain assessment will perform with VAS score. The rescue analgesic 0.4 mg/kg meperidine will be apply intravenously whenever the patient requested to the analgesic.

Ultrasound guided ESP block will perform with 15 ml bupivacaine+ 5 ml lidocaine at the T10 level bilaterally. 0.1 microgram morphine (IV) and diclofenac sodium 75 mg intramuscularly will perform for postoperative analgesia.

In this group Ultrasound guided ESP block will not perform. Postoperative analgesia will provide with 0.1 microgram morphine (IV) and diclofenac sodium 75 mg intramuscularly.

Postoperative pain assessment will perform with 11-point numerical rating scale score and numerical scale point which described by resident will record. Higher points show that severe pain. 0 point shows no pain.10 point shows unbearable pain.

When the higher points numerical scale point (4<) observed, additional analgesics will apply. An than, totally consumption of rescue analgesic requirement (meperidine consumotion) will calculate.
