Brief Summary

Total 100 patients of ASA  group I and II between 25 and 50 years of age undergoing surgery below umblicus under spinal analgesia will be studied. The patients will divided in two groups of 50 patients each. patients of group B will receive 3.0 ml of ) 0.5% Bupivacaine heavy and 0.4 ml of Normal Saline, while patients of group BM will receive 0.5% Bupivacaine heavy and 0.4 ml (5.0 mg) of preservative free Midazolam. The drugs will be prepared by separate anaesthsiologist not involved in the study and will be given by separate anaesthesiologist. Patients of both the groups will be pre-loaded with 15 ml of Ringer Lactate solution before spinal analgesia. On arrival in operation theatre patients will be monitored with ECG, Non invasive blood pressure, Heart rate and pulse oximetery. The parameters will be recorded as base line. With full aseptic precautions lumber puncture will be performed in sitting position in L 3- 4 space by mid line approach in all patients. Lumber puncture will be performed with 25 gauge Quinke spinal needle. After successful lumber puncture the drug will be injected in 15 seconds and patient will be placed in supine position with slight elevation of head (15 to 20 degrees) for at least 20 min before positioning for surgery. The highest dermatome level of sensory block will be assessed by short bevel injection needle after bliding the patient’s eyes in mid axillary line bilaterally . The process of assessing the block will be explained to patients before procedure. Intraoperative ECG, heart rate, blood pressure and Spo2 will be monitored. Hypotension and bradycardia if noted will be treated with I/V Ephedrine 5 to 10 mg and Crystalloid solution. Bradycardia will be treated with I/V Atropine 0.6 mg . Time for four segment sensory block regression will be noted and recorded. Time of recovery of motor block to L 2 level (Hip flexion) will be recorded. Post operative analgesia will be evaluated by  Standard Visual Analogue Scale (0-10). The patients will be requested to inform immediately the feel of pain and time will be noted. The time of first rescue analgesia will be noted. The patients will be observed for any side effects and will be noted and treated if any appeared.
