SUPRACLAVICULAR BLOCK THESIS

SUPRACLAVICULAR BLOCK THESIS

All episodes of local anaesthetic toxicity or haemodynamic changes requiring anaesthesiologist intervention increased IV fluids or inotropes were recorded as adverse events. Time of onset for motor blockade is less in our study when compared to a similar study done by Hickey et al. Patients were placed in the supine position with the head turned slightly away from the side to be blocked and the arm placed alongside the body. J Anaesthesiol Clin Pharmacol ; However, we found that increasing the concentration of Ropivacaine from 0. The duration of analgesia was significantly prolonged in group LD Researchers have demonstrated lesser cardiac depression and fewer CNS effects when ropivacaine is injected intravenously [ 6 ].

Ann Med Health Sci Res ;3: A comparison of 0. Increasing the concentration of ropivacaine from 0. Conclusion The onset of sensory and motor block was similar in all the three groups. The objective of this study was to demonstrate the anesthetic efficacy of levobupivacaine in brachial plexus block, using the perivascular subclavian approach, by comparing it to racemic bupivacaine. Use of dexmedetomidine along with bupivacaine for brachial plexus block. However, there were no statistically significant difference in mean duration of sensory and motor block between Group B 0.

The onset of sensory block and motor block was The random numbers were kept concealed in opaque sealed envelopes and were opened after obtaining informed consent from the patient. Show full item record. Together, these observations enhance our understanding of the anatomic dynamics involved in brachial plexus blockade, and the thesis presents a new model based on the rigid anatomy surrounding the plexus.

The anesthetic efficacy of levobupivacaine in brachial plexus block was similar to that of the racemic solution commonly used.

However, being a very vascular area, brachial plexus blockade can set a potential place for absorption of local anaesthetics and the development of systemic toxicity. Duration of analgesia was the primary outcome. The site that triggered muscular response to a stimulus equal to or lower than 0.

In addition, sensory block was also assessed by pinprick every 4 min in the C5-T2 dermatomes. Multiple comparison test with Bonferroni correction showed there was statistically significant difference in mean duration of sensory block between Group A 0. However, when compared to bupivacaine group, recovery of motor functions was faster in both the ropivacaine groups.

Informed written consent was obtained after explaining the procedure to the patients in the language they understood. Peripheral nerve stimulation with insulated and uninsulated needles: There were no adverse effects observed in patients in the perioperative period, neither CNS nor CVS adverse effects, and were comparable among the three study groups which was again consistent with the study done by Hickey et al.

Supraclavicular Regional Anaesthesia Revisited

The results of our study suggest that 0. The duration of analgesia was significantly prolonged in group LD Conclusion On the basis of our study, conclusions were drawn that onset of action of sensory, motor block was similar in all the groups.

Group A received 30 ml of 0. A gauge, mm, insulated, blunt needle and a nerve stimulator was used to identify the brachial plexus. How to cite this URL: Please review our privacy supraclavicylar.

  WHAT IS THE NARRATIVES THESIS STATEMENT THE SMALL THINGS

Worldwide, long acting bupivacaine has been the most popular local anaesthetic for supraclavicular block in patients undergoing elective upper limb surgeries.

Ninety patients of age 18 to 60 years belonging to American Society of Anaesthesiologists ASA status 1 supravlavicular 2, admitted to Pondicherry Institute of Medical Sciences were chosen for the study and were divided into three groups. Effects of adding dexmedetomidine to levobupivacaine in axillary brachial plexus block. The ideal dose of dexmedetomidine for brachial plexus block is a matter of debate.

Totally 90 patients were recruited into the study.

The results have added to the knowledge base of applied anatomy: Various local anaesthetic agents and adjuvants supraclaviuclar used for this purpose.

Failure to lose shoulder abduction after 30 min was considered as block failure. The statistical tests used were student t-test, paired t-test, chi-square test and Anova test with multiple comparison. Support Center Support Center.
