Sodium Bicarbonate Ringer's Solution for Preventing and Treating Hyperlactacidemia During Hepatectomy
- Conditions
- Hyperlactacidemia
- Interventions
- Drug: Sodium Bicarbonate Ringer's Solution
- Registration Number
- NCT04547296
- Brief Summary
A variety of reasons lead to a sharp increase in lactic acid levels in patients undergoing liver resection, while leading to hyperlactic acidemia, resulting in decreased cardiac output, elevated blood potassium, and response to catecholamines and insulin Damage, increased risk of kidney damage, poor recovery of liver function, decreased immune function, and prolonged hospital stay. Sodium bicarbonate Ringer injection does not contain lactic acid. HCO3- is metabolized by acid-base neutralization in body fluids, and 90% is CO2 The form is excreted from the body by breathing, and only 10% HCO3- is metabolized by the kidney, without the burden of liver metabolism. Physiological concentration of Cl- avoids perchloric acidosis and kidney damage; physiological concentration of Ca2+ and Mg2+ help maintain the body's electrolyte balance and reduce stress-related arrhythmia.The smooth development of this study will help refine the intraoperative fluid management strategy, improve the patient's intraoperative tissue perfusion, maintain the body's acid-base and electrolyte balance, reduce postoperative kidney damage, and improve the patient's quality of life.
- Detailed Description
This study intends to carry out a high-quality clinical research with design specifications, large sample, multi-center, randomized and controlled methods. From October 9, 2020 to October 9, 2022, participants undergoing hepatectomy surgery under general anesthesia will be recruited. Participants will be randomly assigned, in a 1:1 ratio, to receive Sodium bicarbonate Ringer's solution or control (Acetate Ringer's solution). The randomization sequence will be computer-generated, and randomization will be performed in blocks and will be stratified according to participating center. After entering the operating room, the two groups were pre-dilated with sodium bicarbonate Ringer or acetate Ringer (30 min, 8 ml/kg). After the operation started, the two groups of participants were maintained with 4-5 ml/kg/h Ringer's solution during the operation. Blood gas index (but are not limited to these data) at intraoperative will be recorded. At the same time, other dates will be recorded.The participation of each patient is scheduled for 1 month.
