RESUMEN
Background: Background & objectives :To study the effect of dexmeditomidine as an adjuvant to bupivacaine in brachial plexus block on onset and duration of sensory and motor block, duration of analgesia, level of sedation,perioperative hemodynamic parameters and complications. Methods: fourty patients of ASA Ι and ASA ΙΙ scheduled for upper limb surgery were included in double blind randomised comparison of inj. Dexmeditomidine and inj. Normal saline. We divided patients in two groups. Group A patients were given inj dexmeditomidine 50 microgm (0.5ml) and group B patients were given inj normal saline in brachial plexus block. We recorded time of onset and duration of sensory and motor block, level of sedation, duration of analgesia, hemodynamic changes and side effects in both groups. Results: mean time to onset of sensory block was 7.42±1.39 min in group A and 8.24± 1.35 min and that of motor block was 15.1± 2.6min in group A and 17.0± 2.9min in group B.Total duration of sensory block was 722.15±78.27min in group A and 360.62±61.7min in group B and that of motor block was 600.6± 54.46min in group A and 300.4± 54.26min in group B. Duration of analgesia was 970.36 ± 80.7 min in group A and 480±40.31 min in group B. Conclusion: addition of 50 microgm of inj dexmeditomidine to bupivacaine in brachial plexus block shortens onset and prolongs duration of sensory and motor block, prolongs duration of analgesia and decreases intraoperative requirement of sedatives.
RESUMEN
Background: The hand length can be used as a basis for estimating stature in cases where only fragmentary or mutilated remains of an unknown person are recovered and also in age related loss in stature. Objectives: To investigate the relationship between Personal Stature and Hand Length in living subjects of Gujarat region and derive a population specific formula (regression equation) to estimate Stature from Hand Length. Methods: Height and Hand Lengths were measured of total 510 living subjects (258 males & 252 females) between the age group of 18-25 years belonging to Gujarat Region. Results: A positive correlation was found between Height and Hand Length and it was statistically significant. Regression equation for stature Estimation was formulated using Hand Length in both sexes. Conclusion: Dimensions of Hand can provide good reliability in estimation of stature. Simple linear regression equation so far derived can be used for estimation of height. If either of the measurement (Hand length or Total Height) is known, the other can be calculated. This fact will be of practical use in Medico Legal investigations and in Anthropometry.
