Could We Use Vital Signs and Lactate Levels Together to Predict the Prognosis in Abdominal Pain?

Objectives: Abdominal pain occupies most of the emergency department admissions. This entity leads to research various markers for the early detection of causes in patients presenting with abdominal pain. There is limited data about collaborations between lactate levels and vital signs at admission in abdominal pain. Materials and Methods: Patients aged 18 years and older, who had presented with abdominal pain to the Emergency Department, in total 102 patients, were included to the study. The patients’ demographics, vital signs, abdominal physical examination findings, diagnosis and outcomes of patients were recorded. The 1 ml venous blood samples were collected by blood gase injectors from the patients and lactate levels were analyzed. Results: Female patients’ percentile was 68,6% and mean age was 39 years old. The systolic blood pressure levels were normal in 45 patients, low in 26% patients and high in 29% patients. The seventy-six of the patients had normal pulse rate and 26 of them were tachycardic. Most common diagnosis was non-specific abdominal pain (37,25%) and the least common was ovarian torsion/intracystic hemorrhage (0,98%) and obstruction due to hernia (0,98%). There was no statistically significant relation between lactate level and pulse rate (p=0,637), systolic blood pressure (p=0,052), diastolic blood pressure (p=0,095), respiratory rate (p=0,527), body temperature (p=0,040) and oxygen saturation (p=0,905). Similarly, no significant association occurred between lactate levels and diagnosis and outcomes. Conclusion: Further studies including more patients groups have to be done in order to attain more reliable data about this topic.
