RESUMO
Objective: This study was conducted to evaluate the changes in blood pressure of hypertensive patients having dental extraction under a local anesthetic containing epinephrine
Study Design: Cross-sectional descriptive and analytical study
Place and Duration of Study: This study was carried out at Jinnah Medical and Dental College [JMDC[ from January 2015 to April 2015
Materials and Methods: The data was collected from the patients visiting the Oral Surgery OPD of Jinnah Medical and Dental Colleges, Karachi
The study was conducted at Jinnah Medical and Dental College to evaluate the changes in blood pressure of patient with a known history of hypertension controlled using medications. All the patients underwent uncomplicated dental extraction
The blood pressure was recorded at three times: before the local anesthesia, 3 minutes post local anesthesia, and 3 minutes post extraction. 2 % Lidocaine with adrenaline l:180,000was used for local anesthesia
Careful administration of anesthesia was ensured to avoid direct injection into the bloodstream. In majority of cases only 2 anesthetic ampules were used [only two patient required 3 ampules]
The data was stored in excel worksheet and was analyzed using SPSS
Results: The total sample size was 122 patients seen in the Oral and maxillofacial surgery department of JMDC
There were 52 females and 70 males. Mean age was 46.17 +/- 13.26 years [range 25-78]. The age was further divided into four groups; Group 1: 25-34, Group 2: 35-44, Group 3: 45-54, Group 4: 55 and above. There was no significant change in diastolic and systolic blood pressure blood pressure at three time points. Paired sample T test was used, the only significant difference was in SBP before [SBP1] and after anesthesia [SBP2] [t= -2.28 p=0.045]. No significant change noticed in the DBP values at DBP1, DBP2 and DBP3. Amongst the age group the significant variation in systolic blood pressure was seen in the age group 3 and 4
Conclusion: This study was conducted to find out the changes in blood pressure of patients with a known history of hypertension controlled using medications. The study showed no significant changes in the observed parameters
