Effects of different types of Ringer’s solution on patients with traumatic haemorrhagic shock: a prospective cohort study

Objective: To compare the fluid resuscitation effect of sodium acetate Ringer’s solution and sodium bicarbonate Ringer’s solution on patients with traumatic haemorrhagic shock. Method: We conducted a prospective cohort study in our emergency department on a total of 71 patients with traumatic haemorrhagic shock admitted between 1 December 2020 and 28 February 2022. Based on the time of admission, patients were randomly divided into a sodium bicarbonate Ringer’s solution group and sodium acetate Ringer’s solution group, and a limited rehydration resuscitation strategy was adopted in both groups. General data were collected separately, and the patients’ vital signs (body temperature, respiration, blood pressure and mean arterial pressure (MAP)), blood gas indices (pH, calculated bicarbonate (cHCO₃⁻), partial pressure of oxygen (PaO₂), partial pressure of carbon dioxide (pCO₂) and clearance of lactate (CLac)), shock indices, peripheral platelet counts, prothrombin times and plasma fibrinogen levels were measured and compared before and 1 h after resuscitation. Results: The post-resuscitation heart rate of the sodium bicarbonate Ringer’s solution group was significantly lower than that of the sodium acetate Ringer’s solution group (p< 0.05), and the MAP was also significantly lower (p< 0.05). The patients in the sodium bicarbonate Ringer’s solution group had significantly higher pH, cHCO₃⁻and PaO₂values and lower pCO₂and CLac values (p< 0.05) than those in the sodium acetate Ringer’s solution group, and the post-resuscitation peripheral platelet counts and fibrinogen levels were significantly higher, with shorter plasma prothrombin times and smaller shock indices (p< 0.001). Conclusion: Sodium bicarbonate Ringer’s solution is beneficial for maintaining MAP at a low level after resuscitation. The use of sodium bicarbonate Ringer’s solution in limited fluid resuscitation has positive results and is of high clinical value.
