Study: NCT05991466

Intervention type: DRUG
Group type: ACTIVE_COMPARATOR
Intervention: Dexmedetomidine
Description: All patients will be assessed clinically and investigated for exclusion of any of the above-mentioned contraindications. The required laboratory work will be: complete blood count (CBC); prothrombin time and concentration (PT\&PC); partial thromboplastin time (PTT); bleeding time (BT); clotting time (CT); liver function tests and kidney function tests.~Before arrival to the operation room (OR), women will be premedicated by metoclopramide 10mg and ranitidine 50 mg intravenous. Intra operatively, hemodynamics will be recorded baseline before spinal anaesthesia , after its performance, every 3 minutes until delivery and then every 10 minutes till the end of the CS. Any change within 20% of baseline will be accepted and any changes more than 20% will be managed according to guidelines. All groups will be anaesthetized to preform CS with conventional spinal anaesthesia. The TAP block group will receive a landmark orientated Ultrasound guided bilateral TAP block.
