Abstract: Purpose To measure the preoperative fasting durations with respect to time of the day and its effect on vital parameters and electrocardiogram in elderly patients undergoing surgery under spinal anesthesia. Methods This study investigated 211 patients older than 60 years undergoing elective surgery under spinal anesthesia. Patients scheduled for surgery in morning hours (AM) and afternoon hours (PM) were compared. Patients fasting hours and repeated measurements of mean… Show more

“…Secondly, a search through the websites of 25 larger (ie, at least 600 beds) Dutch hospitals showed that hospitals commonly advise to fast from solid food and fluids for 6 and 2 hours, respectively, before admission time, including on the website of 1 of the hospitals that participated in our study. Thirdly, prolonged fasting was found in other countries with comparable sample sizes such as Iceland, 21 Turkey, 31,50 Brazil, 51,52 South Africa, 14 and Oman, 53 including low awareness of hospital staff in Germany 13 and Egypt. 54 Therefore, despite representing only 2 settings, we are convinced that our findings are relevant and indicate throughout revision of current fasting guidelines and practices.…”

“…30 Furthermore, prolonged fasting may be associated with cardiac stress and hypothermia. 31 Emotional consequences include patients' feeling loss of control, as they are not allowed to have food or drinks. Patients are aware that they have to fast, but they sometimes do not understand what fasting or nil-per-mouth means and why it is recommended.…”

“…Prolonged preoperative fasting should be avoided (except in cases with an intraabdominal pathology). Yeniay et al [50] measured preoperative fasting duration with respect to time of the day and its effect on vital parameters and ECG in elderly patients undergoing surgery under spinal anesthesia (SA). The fasting times were far longer than recommended, with 15-hour fasting being related to a transiently increased cardiac stress and mild hypothermia.…”

“…First and foremost, Yeniay et al found that preoperative fasting time is one of the risk factors for GAIH and patients who fast very long are more likely to have GAIH [2]. However, the preoperative fasting times were not clearly described in the method section.…”
