عنوان انگلیسی Comparison Between Dexamethasone Versus Clonidine as Adjuvants to 0.75% Ropivacaine in Ultrasound Guided Brachial Plexus Block for Upper Limb Orthopedic Surgeries: A Randomized Prospective Clinical Study
چکیده انگلیسی مقاله Background: Ropivacaine is an amino-amide local anesthetic, extensively used for peripheral nerve blocks, numerous adjuvants have been added to Ropivacaine to prolong the duration of analgesia. Aim: To compare the effectiveness of adding Dexamethasone to Ropivacaine versus adding Clonidine to Ropivacaine in ultrasound guided supraclavicular brachial plexus block in terms of analgesic duration, onset & duration of sensory and motor blockade. Methods: A prospective randomized single blinded study carried out in 70 patients of ASA grade I and II, aged 20 to 60 years scheduled for elective upper limb orthopedic surgeries. Patients were randomly allocated into two groups, Group RC - patients received 20ml of 0.75% ropivacaine along with 1mcg/kg of clonidine diluted to 2ml of normal saline, Group RD - patients received 20ml of 0.75% ropivacaine along with 8mg of dexamethasone (2ml). Statistical Analysis: Onset & duration of sensorimotor blockade, duration of analgesia was assessed by Unpaired t-test. If p-value <0.05, results were statistically significant & p-value <0.001 were highly significant. Results: Duration of analgesia is superior and statistically significant in Group RD (1,172.57± 18.37 vs 931.09± 16.3). Onset time for sensory (3.14 ± 1.00 vs 9.71± 1.23) and motor (7.60 ± 1.54 vs 13.66± 1.03) block is rapid in Group RD. Duration of sensory (1,106.57± 20.28 vs 786.26± 31.43) and motor (997.74 ± 24.9 vs 674.57 ± 2.18) block is enhanced in Group RD Conclusion: Dexamethasone as an adjuvant to ropivacaine provided superior post-operative analgesia, faster onset and longer duration of sensory and motor blockade.
