The usage of Sodium Lactate Ringer Injection during gastric tube insertion is mainly to inject it into the gastrointestinal tract through a gastric tube to regulate electrolyte balance and supplement fluid volume in the body. The following is a specific usage description: Generally, the dosage of Sodium Lactate Ringer Injection is accurately calculated based on the patient's weight and degree of dehydration. When an adult is mildly dehydrated, the initial injection volume can be around 500-1000 milliliters, and then adjusted according to the actual situation.
After successful insertion of the gastric tube, a syringe should be used to slowly extract an appropriate amount of Sodium Lactate Ringer Injection. Generally, the amount extracted each time should not exceed 500 milliliters to prevent rapid injection from causing discomfort to the patient. Connect the syringe that has extracted the injection solution properly to the gastric tube, turn on the slow injection mode, and control the injection speed at around 20-30 drops per minute to allow the injection solution to enter the gastrointestinal tract smoothly. If the patient has special conditions such as gastrointestinal dysfunction, the injection speed should be appropriately reduced to 10-15 drops per minute, and the patient should be closely observed for adverse reactions such as bloating and abdominal pain. For pediatric patients, the dosage of Sodium Lactate Ringer Injection should be strictly calculated according to body weight, with a dosage of about 20-40 milliliters per kilogram of body weight, and the injection process should be handled with caution.
During the injection process, the gastric tube should be withdrawn from time to time to check for any residual gastric contents. If there is a large amount of residual content, some contents should be withdrawn before continuing the injection to avoid excessive gastric pressure. After the injection of Sodium Lactate Ringer Injection is completed, the gastric tube should be rinsed with a small amount of physiological saline, usually 20-30 milliliters, to prevent residual injection from blocking the gastric tube. If the patient needs to receive multiple injections of Sodium Lactate Ringer Injection, the interval between the two injections should be determined based on the patient's condition and gastrointestinal tolerance, usually 2-4 hours apart. During the entire process of injecting sodium lactate Ringer injection through a gastric tube, the patient's vital signs such as heart rate, blood pressure, respiration, etc. should be closely monitored, and any abnormalities should be promptly addressed.

When injecting, it is important to ensure that the temperature of the sodium lactate Ringer injection is close to human body temperature, around 37 ℃. Both too cold and too hot can stimulate the gastrointestinal tract and cause discomfort symptoms.
