SUPRACLAVICULAR BLOCK THESIS

Our study also sought to assess the onset and duration of sensorimotor blockade, haemodynamic effects, sedation and adverse effects. Injection Midazolam 2mg intravenous was administered before proceeding to give the supraclavicular block, to relieve anxiety. Facilitatory effects of perineural dexmedetomidine on neuraxial and peripheral nerve block: An adjuvant making large inroads into clinical practice. Find articles by Ranjan R. Sensory onset time was time approximately 5 minutes and motor was approximately 10 minutes in both the group which is much faster compared to our group and it can be explained that addition of clonidine as an adjuvant potentiated the onset in their group compared to ours [ 14 ]. Materials and Methods Ninety patients of age 18 to 60 years belonging to American Society of Anaesthesiologists ASA status 1 or 2, admitted to Pondicherry Institute of Medical Sciences were chosen for the study and were divided into three groups.

Introduction Ever since William Stewart Halsted and Richard John Hall first reported the use of cocaine to block upper extremity nerves in , brachial plexus regional anaesthesia has been used extensively by anaesthesiologists worldwide [ 1 ]. No side effects were recorded in the study. National Center for Biotechnology Information , U. The study population consisted of 90 patients posted for elective forehand surgery. Injection Midazolam 2mg intravenous was administered before proceeding to give the supraclavicular block, to relieve anxiety.

Various local anaesthetic agents and adjuvants are used for this purpose. Ever since William Stewart Halsted and Richard John Hall first reported the use of cocaine to block upper extremity nerves inbrachial plexus regional anaesthesia has been used extensively by anaesthesiologists worldwide [ 1 ].

Supraclavicular Regional Anaesthesia Revisited

After obtaining ethical and institutional committee approval, 90 patients of the age group of 18 to 60 years, belonging to ASA physical status I or II scheduled to undergo elective arm, forearm and hand surgery under regional anaesthesia in this Institution were included in this study. They documented a mean onset of motor blockade of 48 min min at the hand at the C5 and C6 dermatomes which was substantially longer compared to our findings.

Materials and Methods Ninety patients of age 18 to 60 years belonging to American Society of Anaesthesiologists ASA status 1 or 2, admitted to Pondicherry Institute of Medical Sciences were chosen for the study and were divided into three groups.

There were five cases of block failure and according to our protocol they were converted to GA 3 patients from Group A and one each from Group B and Group C. Although safe, ropivacaine is found to be less potent than bupivacaine and has a slightly shorter duration of action along with some motor sparing qualities [ 8 ].

A dose-response study of caudal dexmedetomidine with ropivacaine in pediatric day care patients undergoing lower abdominal and perineal surgeries: Comparative evaluation of 0. Pharmacokinetics and pharmacodynamics of bupivacaine enantiomers in the isolated perfused rabbit heart.

Totally 90 patients were recruited into the study. The University of Auckland.

The study technique evolved to incorporate the modern technology, becoming ultrasound-guided axillary tunnel block. Sensory onset time was time approximately 5 minutes and motor was approximately 10 minutes in both the group which is much faster compared to our group and it can be explained that addition of clonidine as an adjuvant potentiated the onset in their group compared to ours [ 14 ]. Ann Med Health Sci Nlock ;3: How to cite this article: A double-blind randomised trial.

Onset and duration of sensorimotor blockade, haemodynamic variables, sedation score, and adverse effects were secondary outcomes. Group LD50 received 29 ml of 0. Find articles by Ranjan R.

Following this supraclavicular brachial plexus block was given with 30ml of three different solutions, i.

The statistical tests used were student t-test, paired t-test, chi-square test and Anova test with multiple comparison. Heart rate and blood pressure were recorded before pre-medication and administration of the block and at 2, 5, 10, 15, 20, 25, 30, 45 and 60 minutes and thereafter every 30 minutes for 2 hours post-operative in the PACU.

  FLICKA KATYS ESSAY

Multiple comparison test with Bonferroni correction showed there was statistically significant difference in mean duration of sensory and motor block between Group A 0. Ultrasound-guided single injection infraclavicular brachial plexus block using bupivacaine alone or combined with dexmedetomidine for pain control in upper limb surgery: Worldwide, long acting bupivacaine has been the most popular local anaesthetic for supraclavicular block in patients undergoing elective upper limb surgeries.

In Group A, supraclavicular block was given with 0. Duration of sensory and motor block was recorded along with peri-operative haemodynamic monitoring. Indian Journal of Anaesthesia. 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. Conclusion On the basis of our study, conclusions were drawn that onset of action of sensory, motor block was similar in all the groups.

An adjuvant making large inroads into clinical practice. Comparative pharmacokinetics of bupivacaine and ropivacaine, a new amide local anaesthetic. Indeed, for this reason, it was often avoided by many practitioners for fear of both clinical and medicolegal consequences. Discussion Brachial plexus block has long been considered a safe method when proper technique is followed, which includes monitoring and patient selection.
