Patients were randomly allocated by lottery method to either the group I (n=50) to whom 0.5% hyperbaric bupivacaine was given or group II (n=50) to which 0.75% hyperbaricbupivacaine was administered. Hemodynamic parameters were noted 03 minutes apart for first 30 minutes. Block level was confirmed to cold using ethyl chloride spray. Pain, uneasiness, nausea and vomiting were also noted. Student t-test and Chi square tests were applied where appropriate.</span></p><p><strong><span style="text-decoration: underline;">RESULTS: </span></strong></p><p>Both groups were comparable in terms of age, weight, height<br />and duration of surgery. There was no significant difference between<br />heart rate, fall in blood pressure in both the groups. Block level at T4<br />level was observed in 78% & 50% in group I & II respectively and at T6 level in 22% & 50% in group I & II respectively (p<0.05). Uneasiness/discomfort (48%) and nausea/vomiting (34%) were observed in group II only (p<0.05)</p><p> </p><p><strong><span style="text-decoration: underline;">CONCLUSION:</span></strong> <span class="fontstyle0">Hemodynamic parameters in both groups showed no<br />significant difference. However, patients administered with 0.5% hyperbaric bupivacaine for lower segment caesarean section showed more appropriate levels of block, less incidence of nausea and vomiting, and more patient comfort as compared to 0.75% hyperbaric bupivacaine.</span></p><p><strong><span style="text-decoration: underline;">KEY WORDS:</span><span style="text-decoration: underline;"> </span></strong>Bupivacaine (MeSH), Anesthesia; Spinal (MeSH), Cesarean Section (MeSH), Hemodynamic parameters (Non-MeSH), Level of block (Non-MeSH)</p>}, number={2}, journal={KHYBER MEDICAL UNIVERSITY JOURNAL}, author={amjad, Qurrat-ul-ain and sharif, Asjad and khan, Amanat}, year={2016}, month={Oct.}, pages={79–81} }
