Knowledge of handling medical emergencies among general dental practitioners pan India: a cross-sectional survery.

BACKGROUND: Medical emergency situations in dental clinics have been contemplated to be an issue in most of the countries by reason of dentist's lack of knowledge and preparedness to attend emergency situations in dental offices. The aim of this paper is to observe the knowledge, attitude, and perceived confidence of the general dental practitioners regarding emergency medical care and its practical application. Questionnaire on knowledge assessment was circulated among 500 dentists using printed questionnaire formats and various social media platforms. The questionnaire included details on treating hypertensive patients, cardiopulmonary resuscitation training, accessibility of medical emergency equipments in the dental clinics, prevalence of medical emergency cases in the dental office and the self-assessed competence to handle medical emergency situations in the dental clinics. Data was surveyed and scrutinized using the Statistical Package for Social Sciences (SPSS), version 17 (SPSS Inc., Chicago IL). Descriptive statistics was tabulated and Chi square tests was applied. FINDINGS: 500 general dental practitioners pan India were involved in the study (294 were females and 207 were males). They were grouped into different age groups (20-30 yrs, 30-40 yrs, 40-50 yrs, 50 and above) and experience (0-5 yrs, 5-10 yrs and more than 10 years). 279 participants did not attend any medical emergency training whereas, 222 participants from all groups attended training program. It was observed that with increased experience in the field, the knowledge, awareness and confidence to treat medical emergency situation in the dental clinics was better. Dentists should update themselves from time-to-time with the latest technologies in the field and need to attend training programs to handle any medical emergency situations in the dental offices. Medical emergencies in a dental clinic can be encountered at any point of time and the clinician should have apt knowledge in handling such situations. Majority of the dentists feel subdued in managing medical situations in dental offices. Training and workshops for handling medical situations in the dental offices should be mandated at the undergraduate and postgraduate levels. This will help the dentist to shape one's confidence in managing such situations without apprehension. Availability of proper infrastructure and equipments is recommended in every dental clinics so as to ease the handling of the situation. CONCLUSION: This paper enlightens the need of basic life support training on regular basis among the dentists to improve the competence among them and to improve the confidence in handling such situations.

The ability of live three-dimensional transesophageal echocardiography to evaluate the attachment site of intracardiac tumors.

In this study, a case of a right ventricular myxoma and a case of a right ventricular hemangioma are used to demonstrate the ability of live three-dimensional transesophageal echocardiography (3DTEE) to assess the site of tumor attachment. Because 3DTEE has the ability to visualize desired structures in multiple planes, we defined the attached portion of the tumors and measured the en face view dimensions. In addition, the improved ability of 3DTEE to evaluate tissue characteristics allowed differentiation of the heterogeneous myxoma and highly vascular hemangioma. On the contrary, because two-dimensional (2D) TEE only allows structures to be viewed in a 2D plane, the attachment site can be located but complete delineation and measurement of area is not possible. As surgical options become less invasive, accurate attachment site location and size will become more important to ensure complete excision.
