Background: Anaesthesia alleviates human sufferings during the surgical procedures. It may be either General anaesthesia or Regional anaesthesia depending upon surgery. General anaesthesia imparts total sensory loss. It also entails poly pharmacy, that is, use of multiple drugs for achieving “Balanced Anaesthesia”. But then, loss of consciousness requires maintenance of airway, even an artificial airway like endotracheal intubation. Use of multiple drugs have their inherent side effects. Hence, general anaesthesia is always stratified in respect to its risk-benefit in individual case scenario. Materials & Methods: The present study was undertaken at Pushpagiri institute of medical sciences Thirunalla Patients posted for sub-umbilical surgeries under intra dural anaesthesia were included in the study. Among 150, Patients were randomly divided into three groups, each group containing 50. Group I (Q) - Patients who received SAB with Quincke 27G needle n=50. Group II (S) - Patients who received SAB with Sprotte 27G needle n=50. Group III (W) - Patients who received SAB with Whitacre 27G needle n=50. Descriptive statistical analysis has been carried out in the present study. Results: There is no statistically significant difference in body height and age group among the study groups p>0.05. This indicates that there is no statistical difference in the inter space selected for lumbar puncture p=0.22. This implies that, there is no statistically significant difference for the number of attempts taken to perform Lumber puncture. p=0.92.This signifies that, there is no statistical difference with respect to Bromage scale among the study groups. p>0.05. Conclusion: Thus, pencil point Whitacre needle is better choice in view of early onset, more height achieved, low incidence of PDPH and less failure rates. However, cost factor should be weighed against the complication.
