What’s the use of fasting water before anaesthesia?

Pre-aesthetic fasting is the reason why the bell of surgery is about to ring, and the doctor’s sweet reminder — “Since tonight, it is imperative that the water be fasted until the operation is complete”, is short but full of deep concern for safety. Behind this is a fine set of things about protecting life and ensuring that the operation is carried out smoothly. Today, let us explore in depth the mystery of the pre-aesthetic fasting.I. The mystery of fasting water: Why is it so important?Keep your breath safe from the risk of suction.The narcotic drugs go into the body and they softly press some of the body’s emergency buttons to allow cough and swallowing to temporarily rest. However, if there are still unincorporated food or liquids in their stomachs at this time, they may enter, reverse the currents, threaten the oesophagus and even the lungs, and cause a “mistake”. This is not only a hotbed of lung infection (e.g. inhalation pneumonia), but also a hidden killer of life. As a result, the fasting of water makes the stomach empty as the first line of defence against such risks.Just breathe. The help surgery is smooth.Every breath of the patient is particularly valuable in the stage of surgery, especially under the overall anesthesia. If there are food residues in the stomach, if misinhalation occurs, it creates an obstacle in the breathing corridor that hinders the smooth flow of oxygen. Even worse, the stimulation of food residues can cause severe cough or bronchial convulsions, adding to the already fragile respiratory system. Thus, the fasting of water is a key to ensuring unhindered air access and smooth operation.Promoting recovery and accelerating recoveryThe path to recovery from surgery and anaesthesia, like a profound baptism of the body, is long and challenging. The pre-operative fasting of water, like the same preventive needle, effectively reduces the occurrence of adverse post-operative reactions such as nausea and vomiting. This not only frees the patient from unnecessary suffering, but also contributes to the rapid recovery of his/her physical strength and the rapid adjustment of his/her mental state, giving a strong impetus to his/her rehabilitation journey.II. Smart practice of fasting water: the art of time managementFaced with the specific requirements of fasting, we need to manage with scientific precision. In general, solid foods must leave the table at least eight hours before the operation, while fresh food such as milk, juice, etc., must be suspended for at least four hours before the operation and, in the case of water, must be cut for at least two hours before the operation. Please note, however, that these periods are for reference only and are subject to adjustment based on the type of operation and the individualized advice of the doctor.III. Smart strategies to address pre-operative hungerThe prolonged fasting of water inevitably gives people a sense of hunger and thirst. But don’t worry, we have many smart strategies to help you:Fragmentation: Let the music flow, make the books the soul’s mate, or talk to the family, so that the passage of time is no longer boring.Small techniques to alleviate thirst: If you are thirsty, you can try to suck on ice or dry lips with wet tampons, so that the cold can temporarily relieve the thirst.Stay relaxed: deep breath, meditation… let the heart find a clean earth in peace. Tensions and anxiety only increase hunger and thirst, while relaxation makes you more comfortable with all this.The seemingly simple pre-aesthetic fasting of water carries profound wisdom and care. Not only is it a solid guarantee of surgical safety, but it is also an important help on the path to the rehabilitation of patients, so let us be scientific in our understanding and in our compliance with this requirement to safeguard together every security and hope of life. May every friend who is about to embark on a surgical journey be able to pass through and recover and be reborn! Anaesthesia.
