简要总结
Preoperative fasting for certain hours is an established practice across the globe to reduce the risk of pulmonary aspiration of gastric contents.
Most of the societies including Indian society of Anaesthesiologists recommend 6-8hrs of nil by mouth for solid and permits consumption of clear fluid up to 2hrs before surgery. However, considering the different types of health care facility in India and adoption to regional cultural practice the actual fasting time for bothe solids and liquids vary widely and may well exceed the expected 6-8 hrs particularly if the case is not scheduled as first case in the list.
Consensus guidelines regarding the optimal fasting duration lack robust evidence across a broad range of ages and surgeries. We hypothesized that different duration of fasting before scheduled surgery would expose the patient to variable degree of hemodynamic consequences like low blood pressure.
The current study is designed to determine the influence of duration of preoperative fasting on blood pressure in early phase (0-5 min) or secondary phase (10-15min) after spinal anaesthesia induction.
