ABSTRACT
Introduction: School children majorly face stress due to the pressure and expectations from their parents besides aca-demics, athletics, etc. It is known that depression, stress increases blood pressure. Such wide variations in blood pres-sure at such a young age can increase the incidence of cerebrovascular accidents, ischemic heart diseases, renal failure and preterm death in the adulthood of such children. This survey will guide the parents and teachers to the various problems student face and how can they help the student cope with it. Method: The blood pressure of each student was taken three times to reduce them to minimise the possibility of errors and the blood pressures of all the students were compared according to their age (13-16 years) and the schooling type (boarders and day scholars). Results:On comparing the prehypertensive stage, the numbers of pre-hypertensives are found to be greater in the age group of 15 years in both day scholars and boarders i.e. 14% and 8% respectively. The on comparing the schooling type the day scholars have a greater number of prehypertensive i.e. 25% than boarders which is 17%. Though pre-hypertensives are higher in the age group of 15 years, but the numbers of hypertensives are more in 14 years of age which is 7% (6% in hypertension stage I and 1% in hypertension stage II) in day scholars and 4% (3% in hypertension stage I and 1% in hypertension stage II) in boarders. In schooling type, a similar trend as that of prehypertension is seen i.e. in day schol-ars 14% students are in hypertension stage I and 3% students are in hypertension stage II making a total of 17% of hypertensive in day scholars. Similarly, in boarders there are 6% in hypertension stage I and 1% in hypertension stage II making 7% hypertensive in boarders, thereby showing a higher percentage of hypertensive in day scholars. Conclu-sion: The study revealed Percentage of students in hypertension stage I and hypertension stage II were found more in day scholars (14% HT STAGE I and 3% HT STAGE II) than boarders (6%HT STAGE I and 1% HT STAGE II) re-spectively. Thus, it can be very well concluded that 17% of day school children and 7% boarders were found to be in hypertensive.
ABSTRACT
Background:Systemic absorption of local anesthetics occurs due to its local vasodilator effects. This leads to inhibi-tory action on the heart which is represented in the form of a decrease in conduction rate, the excitability of myocardi-um and force of contraction. The aim of the present study was to evaluate the effects of Lignocaine and adrenaline combinations on electrocardiogram undergoing dental procedures. Methods:This was a prospective, observational clinical study done in collaboration with the Department of Oral & Maxillofacial Surgery. All patients scheduled for oral surgeries under local anesthesia with Lignocaine 2% and adrenaline (1:80000 or 1:200000) combination of age 18 years or above 150 patients were included in the study. Patients with a history of hepatic, renal, cardiovascular and thyroid disorders were excluded from the study. A standard 12-lead ECG (25 mm/s) was recorded for each patient before administration of drugs (Basal), during the dental procedure (Intraoperative) and immediately after completion of surgical procedure. Results:There was no statistically significant difference seen between the Group A (Lignocaine 2% with 1:80000 adrenaline) and B (Lignocaine 2% with 1:200000 adrenaline) when the age, gender, PR interval, RR interval, mean QT & QTc dispersion, and heart rate were compared. Statistically significant difference was seen in comparing the mean QT & QTc interval, which was higher in Group A. ECG parameters in Group A and B showed a statistically significant decrease in PR interval, RR interval, QT interval, QTc interval, QT dispersion and QTc disper-sion, with the basal, was compared with intraoperative and postoperative findings. The increase in heart rate although was statistically significant in both the groups, it was always within normal limits suggestive of no clinical signifi-cance. There was a statistically significant decrease in QT and QTc interval, QT and QTc dispersion. The change in all these parameters was within the physiologic range. All these relevant parameters for cardiac arrhythmias did not show any arrhythmogenic potential of lignocaine-adrenaline combination in both the groups. Both the combinations are comparable with each other in terms of ECG parameters with changes more with group A suggesting the effect of in-creased concentration of adrenaline. The change in the heart rate and ECG parameters in both the study group might be attributed to the presence of adrenaline in the combination. No cardiovascular morbidities were observed except palpitation. Conclusion:Thus it can be very well concluded that the effects of lignocaine-adrenaline combinations on electrocardiographic parameters are minimal and clinically irrelevant. Both the combination appears to be safe to use in healthy individuals.
