The results showed dexamethazone was more effective in reduction of swelling and pain in comparison with serratiopaptidase. Both dexamethazone and serratiopaptidase had the same effect on trismus.
BACKGROUNDWith the concerns regarding the higher amount of time taken for epidural needle insertion and higher failure rate and complication rate with conventional loss of resistance techniques, various new innovative techniques have been introduced into anaesthetic practice. But the studies comparing these advanced methods on Indian population with conventional methods are scarce.The aim of this study is to compare the efficacy of identification of epidural space using conventional LOR syringe versus automated Epimatic syringe.
An unprecedented surge of hydraulic fracturing activities over the past few years has resulted in a huge demand for quality sand and consequently has increased the supply-demand gap for sand that meets quality standards. Sand used for hydraulic fracturing is qualified based on its ability to meet quality standards described by the American Petroleum Institute (API) and, more recently, by the International Organization for Standardization (ISO). White sand from the Ottawa deposits of the northern US and brown sand from deposits in the southwest US are widely used for hydraulic fracturing. Until recently, these "quality" sand deposits provided sufficient supplies for ongoing needs, but now there is a need to evaluate alternative sources of sand that meets the specifications given by the ISO. In this paper, performance of different sand samples procured from different parts of India and Saudi Arabia are discussed. The sand is characterized by performing sieve analysis, characterizing particle shape (i.e., sphericity and roundness), acid solubility tests, crush-resistance tests, and baseline conductivity experiments, for which the results are presented. Ottawa sand generated 7.7% fines, whereas one of the alternatives generated 8.1% fines at 4,000 psi. Similarly, conductivity for Ottawa and an alternative sand sample was 4,850 and 4,770 md-ft respectively at closure stress of 2000 psi. In conclusion, the results show less than 2% variation between Ottawa and the best alternative sand sample. Considering stringent ISO requirements, few alternatives for widely used Ottawa sand have been identified. Analysis performed in this study will help in evaluating locally available sand, which should provide more security of supply and economic benefits.
BACKGROUND The surgeries in the upper limb can be done either by general or regional anaesthesia or by the combination of both. 1 Regional blockade has wide application in providing surgical anaesthesia and analgesia as well as in treating chronic pain syndromes. Regional anaesthesia has several advantages in the postoperative period compared with general anaesthesia including decreased sedation, decreased nausea and vomiting, early discharge from the recovery room and a smooth transition to pain control as the block effects gradually dissipate. The first demonstration of axillary approach to brachial plexus was done by William Halsted in 1884. He injected cocaine under direct vision. The first percutaneous axillary block was done by G. Hirschel in 1911. The axillary approach to brachial plexus blockade provides satisfactory anaesthesia for elbow, forearm and hand surgery. 2 Aims and Objectives-To evaluate the effect of adding dexmedetomidine as an adjuvant with levobupivacaine in axillary brachial plexus block and to evaluate the adverse effect and onset time for sensory and motor blockade during analgesia. MATERIALS AND METHODS This prospective, randomised, controlled trial study was conducted in Govt. Mohan Kumaramangalam Medical College, Salem from 2016-2017. Ethical committee clearance was duly obtained from the Hospital. For the sake of convenience, it was decided to include 64 subjects in the study with 32 subjects randomised to each of the two study groups. Randomisation of the population is allocated into these defined groups according to computer generated random numbers. RESULTS This study shows the addition of Dexmedetomidine to Levobupivacaine in axillary brachial plexus block results in a shorter onset time for sensory and motor blockade. It also prolongs the duration of sensory and motor blockade and also the duration of analgesia. However, dexmedetomidine use may also lead to bradycardia. CONCLUSION The addition of 1 mL Dexmedetomidine to 29 mL of 0.5% Levobupivacaine in axillary brachial plexus block results in a shorter onset time for sensory and motor blockade. It also prolongs the duration of sensory motor blockade and also the duration of analgesia in patients between 20 years to 50 years of age undergoing forearm and hand surgeries of both sexes.
Original Research ArticleIn this prospective randomized control study, we compared the clinical efficacy and safety of equal doses (15 mg) of 0.5% Hyperbaric Ropivacaine with 0.5 % Hyperbaric Bupivacaine for lower torso surgeries under Spinal Anaeasthesia. After Ethical Committee clearance and obtaining informed written consent from the patient, 80 patients of ASA 1 and 2 of age group 25-50 years posted for lower torso surgeries in Government. Mohan Kumaramangalam Medical College were included. Study population was divided into 2 groups-GROUP B(Patients in this group received intrathecal 15 mg (3 ml) of 0.5% Hyperbaric Bupivacaine) GROUP R(Patients in this group received intrathecal 15 mg (3 ml) of 0.5% Hyperbaric Ropivacaine which is prepared aseptically immediately before injection by adding 1 ml (250 mg) of autoclaved 25% dextrose ampoule (10 ml) to 2 ml of commercially available sterile preservative free isobaric solution of 0.75% Ropivacaine).From our study we conclude that the duration of sensory block and motor block in patients receiving 0.5 % hyperbaric Ropivacaine was less when compared to the patients receiving 0.5 % hyperbaric bupivacaine
