Evaluation of Preparedness for Medical Emergencies in Dental Practice among Undergraduate and Postgraduate Students

A medical emergency among dental patients can be encountered anytime. It is the responsibility of a dentist to handle the emergency in order to effectively manage it. The assessment of preparedness of medical emergencies would help to bring about required changes in the curriculum in dental institutions. Aim: The aim of this study was to evaluate and compare the knowledge of common medical emergencies among undergraduate and postgraduate students. Methods: A questionnaire based study with a sample size of 200 was conducted among 100 postgraduate and 100 undergraduate students at Kothiwal Dental College and Research Centre to evaluate their knowledge regarding medical emergencies. The questionnaire consisted of thirteen questions. Chi-square test was applied for comparing various parameters between dental postgraduates and undergraduates regarding preparedness for medical emergencies. A P-value of less than 0.05 was considered statistically significant. Results: The results of this study showed that filling health history proforma, recording vital signs, attending workshops on emergency management, performing Basic Life Support, and administering an intramuscular and intravenous injection has statistically significant results among postgraduate and undergraduate students. Conclusion: The results of this study reflect an alarming situation of the capability of dental students to deal with medical emergencies at dental offices.

Medication errors in anesthesia: unacceptable or unavoidable? / Erros de medicação em anestesia: inaceitável ou inevitável?

Abstract Medication errors are the common causes of patient morbidity and mortality. It adds financial burden to the institution as well. Though the impact varies from no harm to serious adverse effects including death, it needs attention on priority basis since medication errors' are preventable. In today's world where people are aware and medical claims are on the hike, it is of utmost priority that we curb this issue. Individual effort to decrease medication error alone might not be successful until a change in the existing protocols and system is incorporated. Often drug errors that occur cannot be reversed. The best way to ‘treat' drug errors is to prevent them. Wrong medication (due to syringe swap), overdose (due to misunderstanding or preconception of the dose, pump misuse and dilution error), incorrect administration route, under dosing and omission are common causes of medication error that occur perioperatively. Drug omission and calculation mistakes occur commonly in ICU. Medication errors can occur perioperatively either during preparation, administration or record keeping. Numerous human and system errors can be blamed for occurrence of medication errors. The need of the hour is to stop the blame - game, accept mistakes and develop a safe and ‘just' culture in order to prevent medication errors. The newly devised systems like VEINROM, a fluid delivery system is a novel approach in preventing drug errors due to most commonly used medications in anesthesia. Similar developments along with vigilant doctors, safe workplace culture and organizational support all together can help prevent these errors.

Resumo Os erros de medicação são as causas mais comuns de morbidade e mortalidade dos pacientes. Além disso, esses erros aumentam os encargos financeiros da instituição. Embora o impacto varie de nenhum dano a efeitos adversos graves, inclusive o óbito, é preciso estar atento à ordem de prioridades porque os erros de medicação são evitáveis. Na atualidade, com as pessoas cientes e os processos médicos em evidência, frear esse problema é de extrema prioridade. O esforço individual para diminuir os erros de medicação pode não obter sucesso até que uma mudança nos protocolos e sistemas existentes seja incorporada. Muitas vezes, os erros de medicação ocorridos não podem ser revertidos. A melhor maneira de "tratar" esses erros é impedi-los. Os erros de medicação (devido à troca de seringa), de overdose (devido a mal-entendido ou preconcepção da dose, mal uso de bomba e erro de diluição), de via de administração incorreta, de subdosagem e de omissão são causas comuns de erro de medicação que ocorrem no período perioperatório. A omissão e erros no cálculo de medicamentos ocorrem comumente em UTI. Os erros de medicação podem ocorrer no período perioperatório, tanto durante a preparação e administração quanto na manutenção de registros. Um grande número de erros humanos e do sistema pode ser responsabilizado pela ocorrência de erros de medicação. A necessidade do momento é parar o jogo da culpa, aceitar os erros e desenvolver uma cultura segura e "justa" para evitar os erros de medicação. Os sistemas recém-criados, como o Veinrom, um sistema de administração de líquidos, é uma nova abordagem na prevenção de erros de medicação devido aos medicamentos mais comumente usados em anestesia. Desenvolvimentos semelhantes, juntamente com médicos vigilantes, uma cultura de local de trabalho seguro e apoio organizacional, todos em conjunto podem ajudar a evitar esses erros.

Evaluation of Three Different Regression Equations Based Mixed Dentition Analysis in Children of Moradabad City, India

Objective: To assess the accuracy and applicability of three regression equations based mixed dentition analysis in children of Moradabad city, India. Material and Methods: Actual mesiodistal width of maxillary and madibular incisors, canines and premolars of 100 children (50 male and 50 female) aged 11-14 years were measured on dental cast with electronic digital vernier caliper. The analysis of Tanaka- Johnston, Ling-Wong and Jaroontham-Godfrey regression equations were tested on the dental casts. All analyses were performed on SPSS software. Data were summarized as Mean ± standard deviation (SD) paired observations were compared by paired t-test (two-tailed test) while independent groups were compared by independent Student's t-test. The level of significance was at P < 0.001. Results: The analysis of Tanaka-Johnston, Ling-Wong, Jaroontham-Godfrey regression equations tended to overestimate the mesiodistal width of the canines and premolars with the actual measured values. Conclusion: All the three regression equations based mixed dentition overestimated the mesiodistal width of canines and premolars in Moradabad population.

Co-relation of body mass index, dental caries and periodontal status with fluorosis in different high fluoridated areas of Haryana state, India.

Background and Aim: The aim of the present study is to compare the effect of corticotomy versus prostaglandin E1 injection in human subjects on rate of tooth movement, anchorage loss and their effect on crest bone height and root length. Settings and Design: Clinical interventional study. Split mouth design was used. Materials and Methods: Study was done on 32 regular orthodontic patients. A volume of 100 mcg of prostaglandin E1 was injected on the right side once in 2 weeks and on the left side corticotomy was performed, and canine retraction was started on both sides simultaneously. The rate of space closure and anchorage loss was assessed with casts. The root length and crestal bone height changes were assed with IOPAs. The comparison of rate of tooth movement, anchorage loss, crestal bone height and root length changes between the sides were statistically analyzed using paired t-test. Results: The average rate of space closure on right side was 0.36 mm/week with a standard deviation of 0.05 mm/week and on the left side average rate of space closure was 0.40 mm/week with a standard deviation of 0.04 mm/week. The difference between the rate of closure between the right side and left where found to be statistically significant (P = 0.003). The anchorage loss, the crestal bone height changes and root length changes were not statistically significant. Conclusion: The rate of tooth movement was significantly more with corticotomies when compared with given dose of prostaglandin injection.

Comparison between continuous non-invasive estimated cardiac output by pulse wave transit time and thermodilution method.

Aims and Objectives: Cardiac output (CO) measurement is essential for many therapeutic decisions in anesthesia and critical care. Most available non‑invasive CO measuring methods have an invasive component. We investigate “pulse wave transit time” (estimated continuous cardiac output [esCCO]) a method of CO measurement that has no invasive component to its use. Materials and Methods: After institutional ethical committee approval, 14 adult (21–85 years) patients undergoing surgery and requiring pulmonary artery catheter (PAC) for measuring CO, were included. Postoperatively CO readings were taken simultaneously with thermodilution (TD) via PAC and esCCO, whenever a change in CO was expected due to therapeutic interventions. Both monitoring methods were continued until patients’ discharge from the Intensive Care Unit and observer recording values using TD method was blinded to values measured by esCCO system. Results: Three hundred and one readings were obtained simultaneously from both methods. Correlation and concordance between the two methods was derived using Bland‑Altman analysis. Measured values showed significant correlation between esCCO and TD (r = 0.6, P < 0.001, 95% confidence limits of 0.51-0.68). Mean and (standard deviation) for bias and precision were 0.13 (2.27) L/min and 6.56 (2.19) L/min, respectively. The 95% confidence interval for bias was ‑ 4.32 to 4.58 L/min and for precision 2.27 to10.85 L/min. Conclusions: Although, esCCO is the only true non‑invasive continuous CO monitor available and even though its values change proportionately to TD method (gold standard) with the present degree of error its utility for clinical/therapeutic decision‑making is questionable.

Real-time three-dimensional transthoracic echocardiography.

BACKGROUND: Complex anatomy of intra-cardiac structures requires spatial orientation of image in three dimensions for better understanding and enhanced image interpretation. We evaluated the feasibility and efficacy of the emerging 'real-time three-dimensional transthoracic echocardiography' technique for comprehensive assessment of cardiac anatomy, physiology, pathomorphology and pathophysiology in patients with structural heart disease. METHODS AND RESULTS: Patients with structural heart disease (n=152) were evaluated by conventional two-dimensional transthoracic echocardiography and real-time three-dimensional transthoracic echocardiography using standard protocol. Fifty-six cases were of rheumatic etiology with multi-valvular involvement (mitral stenosis: 32; mitral regurgitation: 29; tricuspid regurgitation: 8; aortic valve disease: 11) and 21 cases of non-rheumatic valvular heart disease. A total of 38 congenital heart disease patients were examined including 23 patients with atrial septal defect. Left ventricular function (n=20) and right ventricular function (n=10) were also assessed using dedicated software. CONCLUSIONS: Results of real-time three-dimensional transthoracic echocardiography mitral valve area assessment by planimetery are comparable to two-dimensional transthoracic echocardiography with additional information about surface anatomy of leaflets and the subvalvular apparatus in real time with clear demarcation of commissural fusion and scallops of leaflets. Enface view of atrial septal defect with direct visualization of shape, size and number of defects, tricuspid valve area by planimetery, right ventricular shape, objective assessment of ventricular volumes and regurgitation vena contracta area are the fields where three-dimensional transthoracic echocardiography was of additive value to conventional two-dimensional transthoracic echcardiography. This study proves clinical feasibility of real-time three-dimensional transthoracic echocardiography but requires further validation of quantitative observations.
