A variety of receptor mediated nociception on peripheral sensory axons and the peripheral administration of appropriate drugs (adjuncts) may have analgesic benefit without the disadvantage of systemic adverse effects and it may also allow reduction in the total dose of local anaesthetic used. Recent studies suggest that α2 agonists when combined with local anaesthetics extends the duration of regional anaesthesia. Thus, in the present study, we investigated the effects of adding dexmedetomidine 50 µg to a 30 mL of local anaesthetic solution in supraclavicular brachial plexus block with respect to onset and duration of motor and sensory block and duration of analgesia.
METHODSSixty patients scheduled for elective forearm surgery were divided into two equal groups in a randomised double blind fashion. In group C (n=30), 20 mL of 0.5% bupivacaine+10 mL of 2% lignocaine+0.5 mL of normal saline and in group D (n=30) 20 mL of 0.5% bupivacaine+10 mL of 2% lignocaine+50 µg dexmedetomidine were given for supraclavicular brachial plexus block using peripheral nerve stimulator. Onset and duration of sensory and motor block were assessed along with total duration of analgesia. Demographic and haemodynamic data were subjected to student's t-test and for statistical analysis of onset time and duration of sensory and motor blocks and total duration of analgesia, unpaired t-test was applied. P-value <0.05 was considered as statistically significant and P-value <0.001 as highly significant.
RESULTSDexmedetomidine added as an adjuvant to local anaesthetic agents for supraclavicular block shortens onset time and significantly prolongs the duration of sensory and motor blocks and duration of analgesia.
Background: Maternal mortality has been the indicator of measurement of maternal health. Over the last decade, identification of severe acute maternal morbidity (SAMM) has emerged as a compliment or alternative to investigation of maternal deaths. A review of causes of SAMM will help to find out the potential problems which in turn will enable women to get the treatment on time. Recent researches have suggested that proper identification of SAMM cases can prove to be a better method to monitor the quality and effectiveness of obstetric care than mortality alone. Although there have been many criteria which have been introduced from time to time to identify these cases, because of vast variation of different level of facilities, these criteria cannot be applied across the regions. WHO has recently come up with certain set of criteria which could be more applicable to low resource settings. Aims & Objective: Present study tried to identify SAMM cases through various criteria and compared the applicability of them in our setup which is resource poor setting catering mainly to a huge rural population. Materials and Methods: It is a prospective study done over a period of one year, from September 2012 to August 2013. All severely morbid pregnant women or who had delivered or aborted within 42days were included. Initial identification of these cases was done on the basis of general criteria and later on other criteria were applied according to the primary obstetric event, clinical features, Lab findings or management provided. A comparison was done amongst all criteria and their individual applicability was checked as per the facility available in our set up. Results: During the study period total 7819 women delivered in the hospital out of which 6498 delivered vaginally and 1321 delivered through caesarian section. Total live births during this period were 5219. The present study found an incidence of severe maternal morbidity/near miss ranging from 5.56 to 40 per 1000 live births. Among 244 women suspected to be SAMM/MNM, 179(73%) met Waterstone's criteria, 48(20%) met Mantel's Criteria and 63(26%) met WHO criteria, 20% women met Mantel and Waterstone's criteria both while 17% met all three criteria. Conclusion: The study of SAMM cases and their identification through suitable criteria can contribute to know its magnitude, as well as to identify most frequent characteristics and clinical conditions which will help to recognize the problems in antenatal services, peripheral health care facilities and referral system. The criteria which are available now cannot be applied uniformly, and need to be tailored to identify more specific criteria according to infrastructure of a particular setting in order to utilize resources effectively.
Purpose:The purpose of this study is to measure intraocular pressure (IOP) and evaluate the correlation between IOP and midnight plasma cortisol (MPC) level in patients with Cushing's disease (CD) and other endogenous Cushing's syndrome (ECS).Methods:This is a cross-sectional study from a single center including newly diagnosed patients with CD or ECS. All patients underwent detailed ophthalmological evaluation. IOP was measured by Goldmann applanation tonometry in the morning and evening on two consecutive days. MPC value was obtained for each patient. The data were compared using paired and unpaired t-test, Mann–Whitney U-test, and Spearman's rank correlation coefficient.Results:Among 32 patients, 22 were CD (68.75%) and 10 patients were other ECS (31.25%). A total of 25 patients (78.12%) in our study group had normal IOP (<22 mmHg), and seven patients (21.88%) had increased IOP (≥22 mmHg). The percentage of patients with normal IOP was found to be significantly higher compared to percentage of patients with high IOP (P = 0.001) using one-sample Chi-square test. Mean MPC value was 468.6 ± 388.3 nmol/L in patients having IOP ≥22 mmHg and 658.5 ± 584 nmol/L in those with IOP <22 mmHg from both CD and ECS groups, but the difference was not statistically significant. No correlation was found between IOP and MPC (Spearman's rank correlation rho = −0.16 [P = 0.38]).Conclusion:In CD and ECS patients, IOP elevation is an uncommon feature, and high IOP in either group does not correlate with MPC level.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
