Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: magnesium sulphate as an adjuvant to local anesthetic in erector spinae plane block; Ultrasound-guided Erector spinae plane (ESP) block will be done with the patient in a sitting position depending on the surgical site (lt. or Rt.) ESP block will be given using high-frequency linear u/s transducer, the probe is placed in longitudinal orientation lateral to the thoracic third and sixth spinous process, the erector spinae muscle, is identified from the surface, we will deposit 20 ml of 0.25% levobupivacaine into interfacial plane below erector spinae muscle.	Drug: Magnesium sulfate in erector spinae plane block; Ultrasound-guided Erector spinae plane (ESP) block will be done with the patient in a sitting position depending on the surgical site (lt. or Rt.) ESP block will be given using high-frequency linear u/s transducer, the probe is placed in longitudinal orientation lateral to the thoracic third and sixth spinous process, the erector spinae muscle, is identified from the surface, we will deposit 20 ml of 0.25% levobupivacaine into interfacial plane below erector spinae muscle. General anesthesia will be induced with l/kg fentanyl, 2mg/kg propofol, 0.5 mg/kg atracurium and inhalational anesthesia (sevoflurane) No other narcotic, analgesic or sedative will be administrated during the operative period. BP(SystolicBP, DiastolicBP) and HR will be observed and recorded every 30 min till the end of surgery.
Experimental: local anesthetic only in erector spinae plane block; Ultrasound-guided Erector spinae plane (ESP) block will be done with the patient in a sitting position depending on surgical site (lt. or Rt.) ESP block will be given using high-frequency linear u/s transducer, the probe is placed in longitudinal orientation lateral to the thoracic third and sixth spinous process, the erector spinae muscle, is identified from the surface, we will deposit 20 ml of 0.25% levobupivacaine and magnesium sulfate into interfacial plane below erector spinae muscle.
