Assessment of Complications and Haemodynamic Stability with the Use of Dexmedetomidine with Bupivacaine: An Institutional Based Study

Background: Lesser doses of local anesthetic in addition withadditives provides the necessary sensory level with enoughanalgesia. Dexmedetomidine is the S enantiomer ofmedetomidine that carries a high degree of specificity foradrenoreceptor. The present study was conducted with the aimto assess the complications and haemodynamic stability withthe use of dexmedetomidine with bupivacaine.Materials and Methods: The present study was conducted ina prospective manner for a period of 1 year at Department ofAnaesthesiology, Lady Hardinge Medical College & Smt. S. K.Hospital, New Delhi, India. No anesthesiologist enrolled in thepresent study was conscious of the group assigned till theentire 30 subjects were enrolled and the study was completed.After verifying a clear and free flow of the CSF, the drugadministration was completed and the subjects were placed atthe supine position. For every patient, heart rate and meanarterial pressure monitoring was done every 2 min for the initial10 minutes after spinal anesthesia, then after every 5 minutestill 30 minutes and then every 30 minutes till complete motorand sensory recovery. All the data thus obtained was arrangedin a tabulated form and analyzed using SPSS software.Probability value of less than 0.05 was regarded as significant.Results: The present study enrolled 30 subjects with15 patients in each group. The mean age of the subjects was39.22+/-4.67 years. The preoperative BP in Group I was94.67+/-8.22 and in group II was 91.52+/-5.38. There was nosignificant difference between them. There was 1 subject eachin Group I and II with nausea and shivering respectively.Conclusion: The study showed no significant alterations in thehaemodynamic stability the side effects between subjects whoreceived bupivacaine alone or bupivacaine plusdexmedetomidine.
