Patients will be randomly allocated into two groups of 40 patients each:
Group L:will receive 18-20 ml/kg/h of Ringer's lactate starting from conduction of spinal anesthesia.

Patients will be randomly allocated into two groups of 40 patients each:
Group R: will receive 4-6 ml/kg/h of Ringer's lactate starting from conduction of spinal anesthesia.

Intraoperative Complications

Randomization will be done using computer generated table of random numbers in a 1:1 ratio and will be conducted using sequentially numbered, opaque and sealed envelope. The trial will be planned that neither the doctors (investigators) nor the patients will be aware of the group allocation and amount of fluid received. Intraoperative and postoperative data collections will be achieved by the same blinded anesthiologist.
Patients will be randomly allocated into two groups:
Group L: 40 patients who will be subjected to ''liberal" approach of intraoperative 18-20 ml/kg/h of Ringer's lactate starting from conduction of spinal anesthesia.
Group R: 40 patients who will be subjected to ''restrictive" approach of intraoperative 4-6 ml/kg/h of Ringer's lactate starting from conduction of spinal anesthesia.
Blood loss will be replaced if more than 500 ml in a ratio of 3 ml crystalloid: 1 ml blood.
