Spinal anaesthesia is considered a popular and well accepted technique for cesarean section. Hyperbaric bupivacaine is the most common local anesthetic used for spinal anesthesia in term pregnancy undergoing elective caesarean delivery. Levobupivacaine is relatively new long acting local anesthetic that has been produced to address the issue of cardio-vascular and neurological toxicity following inadvertent intravascular injection. The three-dimensional structure of local anesthetic molecules forms two different special configurations R+ and S- forms. The differential affinity of these enantiomers for sodium, potassium and calcium channels results in a significant reduction of neurological and cardiac toxicity of S-enantiomers in comparison of R enantiomers. With Bupivacaine, cardiotoxicity manifests as cardiac arrythmias and severe cardiac collapse that can be rapid irreversible and fatal. In caesarean section, onset as well as sensory and motor block is higher with levobupivacaine than Bupivacaine. Levobupivacaine is S (-) enantiomer which is recently introduced for obstetrics spinal and epidural anesthesia. ^{It has more selective neuraxial blockage.} Dexmedetomidine is a  α₂ adrenergic receptor agonist , an imidazole derivative with the chemical name 4 [(1R)-1- (2,3- dimethyl phenyl) ethyl ] – 3H – imidazole hydrochloride. It exhibits synergism with local anaesthetics prolonging sensory and motor block, delaying the time to the first analgesic, and improving post operative analgesia. Dexmedetomidine is a highly selective activator of the α₂ A receptor acting on the nucleolus of the nucleus, and it can have a sedative and hypnotic effects, while its action on the spinal cord can produce analgesic effects, while its action on the peripheral and CNS can play a role in inhibiting sympathetic excitation. NAAZ et. al, in their study “OPTIMAL DOSE OF INTRATHECAL DEXMEDETOMIDINE IN LOWER ABDOMINAL SURGERIES IN AVERAGE INDIAN ADULT”, concluded that 10 µgm of DEXMEDETOMIDINE has optimal action and 5µgm did not gave any sedating effect. YUN QI WANG et.al in their study “EFFECT OF INTRATHECAL DEXMEDETOMIDINE ON CAESARIAN SECTION DURING SPINAL ANAESTHESIA; A META ANALYSIS OF RANDAMISED TRIAL”, concluded, 5µgm dexmedetomidine decreases shivering and has no adverse effect on caesarian sections. Hence, we will compare effect of Levobupivacaine heavy with dexmedetomidine versus racemic bupivacaine heavy with dexmedetomidine in spinal anesthesia in cases of caesarean sections.
