Intervention measures for postoperative thirst
(1) Applying cucumber slices to the lips and around the mouth can not only moisten the lips, but also be absorbed by the skin around the mouth, thus moistening the mouth. Cucumber slices can be applied continuously without falling off, which can improve the continuous stimulation, transmit the action potential of afferent nerve impulse with sufficient water to the brain center frequently through the afferent pathway, continuously generate the feeling of sufficient water, and obviously alleviate the thirst of patients. Cucumber is available all year round, which is simple to operate, economical and has almost no side effects. It can be done by teaching patients' families.
Applying lip balm, liquid paraffin or vaseline to lips can also actively moisturize. Sober patients can keep their mouths moist by gargling, brushing their teeth and chewing gum. Wet cotton swabs dipped in water only temporarily moisten lips and have no effect on oral cavity.
② Shorten the time of fasting and water deprivation before operation. It depends on the patient's physical condition, disease characteristics and anesthesia method.
③ Eating and drinking water as early as possible after operation according to the surgical site and the patient's physical condition is beneficial to the recovery of gastrointestinal function, nutritional supplement and electrolyte balance.
④ Rehydration before and after operation can effectively prevent hypovolemia and quench thirst in time.
⑤ It is suggested that the room temperature should be kept at 22~24℃, the humidity should be 70%, and the ventilation should be quiet. Prevent the indoor temperature from being too high and the water from evaporating too fast.
