Brief summary: the study is to assess the efficacy of dexmeditomedine as an adjuvant to the local anaesthetic levobupivacaine in transversus thoracis plane block given bilaterally on the management of post-sternotomy pain.

Detailed description: the patients will fall into one of two groups using an online randomizer. this study is an assessor-blinded interventional controlled study. the first group will recieve transversus thoracis plane block bilaterally where 15 ml of 0.25% levobupivacaine will be given. and the other group shall also undergo a bilateral transversus thoracis plane block with 15 ml 0.25% levobupivacaine and 0.05 ug/kg dexmeditomedine on each side. the primary aim of the study is the 24 hour post-operative morphine consumption.

Eligibility criteria: Inclusion Criteria:

* Adult patients \> 20 years old.
* ASA II to III patients undergoing elective cardiac surgery via a median sternotomy

Exclusion Criteria:

* Patient's refusal.
* Known contraindications to regional blocks, including local skin infections,and coagulopathy.
* Allergies to the local anaesthetics used.
* Patients undergoing complex cardiac procedures.
* Patients with severe chronic obstructive pulmonary disease.
* Patients unable to communicate.
* Patients with chronic pain.
* Patients with severe pulmonary hypertension.
