Brief Summary   Elective lower segment cesarian section is a commonly performed surgical procedure which requires anaesthesia. Most common mode of anaesthesia used is spinal anaesthesia . The drug commonly used to give spinal anaesthesia in such patients is injection bupivacaine 0.5 percent hyperbaric. This study aims to compare the anaesthetic properties and haemodynamic changes caused by the aforementioned drug to isobaric injection bupivacaine 0.5 and its anaesthetic properties and haemodynamic changes.

Inclusion criteria includes patients undergoing elective cesarian section between the ages of 20 and 40. ASA 2. Height more than 150 cms and gestational age of greater than 35 weeks.

Similarly exclusion criteria involves patients undergoing emergency lower section cesarean section , contraindication or allergy to the above used drugs, contraindication to spinal anaesthesia, patient refusal.

The study will be conducted in dy patil school of medicine and hospital, nerul, navi mumbai. Over a period of 2 years.

The study method is randomised control trial double blind.

Sample size is 48.
