RESUMO
OBJECTIVES: Fears related to anesthesia have affected a considerable number of patients going for surgery. The purpose of this survey was to identify the most common concerns about general anesthesia during the preoperative anesthetic clinic in different healthcare settings, and whether they are affected by patients' sex, age, education, or previous experience of anesthesia or not. MATERIALS AND METHODS: Structured questionnaires with consent forms were distributed to patients in their preanesthesia clinic visit in three tertiary hospitals (King Abdul-Aziz Medical City, King Faisal Specialist Hospital, and King Khalid University Hospital) in Riyadh, Saudi Arabia. Patients' demographics and questions related to their fears regarding general anesthesia were included in the questionnaires. All categorical and interval variables were compared statically using a Chi-square test for independence and a t-test, respectively. All statistical tests were declared significant at α level of 0.05 or less. RESULTS: Among 450 questionnaires that were disturbed, 400 questionnaires were collected and analyzed. Eighty-eight percent experienced preoperative fear. The top three causes of their fears were fear of postoperative pain (77.3%), fear of intraoperative awareness (73.7%), and fear of being sleepy postoperatively (69.5%). Patients are less fearful of drains and needles in the operative theater (48%), of revealing personal issues under general anesthesia (55.2%), and of not waking up after surgery (56.4%). Age and gender were significant predictors of the overall fear among preanesthetic patients. Females are 5 times more likely to experience fear before surgery (P = 0.0009). Patients aged more than 40 years old are also at 75% higher risk of being afraid (P = 0.008). CONCLUSION: The majority of the patients going for surgery experienced a fear of anesthesia. Mostly females, especially those over 40, were at a higher risk of being afraid. Fear can bring anxiety which, in turn, might affect the patient's surgery.
RESUMO
OBJECTIVE: To investigate the association of pericardial fat volume (PFV) with coronary artery disease (CAD) in patients with intermediate pre-test probability of ischaemic heart disease assessed by coronary CT angiography. METHODS: From a total of 115 consecutive Iraqi patients who underwent 64-multislice multidetector CT angiography examinations, only 74 patients (females, 38% and males, 68%) with a mean age of 54 ± 8 years were found to be eligible for statistical analysis. The patients were divided into two groups according to the median value of PFV (above and below 100 ml). RESULTS: The median value of PFV in our study was 100 ml (range, 17-319 ml). A significant association was observed between high PFV and significant coronary artery stenosis (p = 0.005), between high PFV and significant left circumflex stenosis (p = 0.021) and between high PFV and the presence of coronary plaque (p = 0.005). Whereas there was no significant correlation between high PFV and coronary calcium score (p = 0.188), between high PFV and number of diseased coronary vessels (p > 0.3), and between high PFV and body weight and body mass index. CONCLUSION: Increased PFV is strongly associated with the presence and severity of CAD. ADVANCES IN KNOWLEDGE: Our study highlights the role of pericardial fat as an emerging biomarker in cardiovascular risk assessment and supports its association with the magnitude of CAD.
