Abstract Background The prehospital patients treated by ambulances and mobile emergency care units (MECU) are potentially critically ill or injured. Knowing the risks of serious outcomes in these patients is important for guiding their treatment. Some settings allow for prehospital arterial blood gas analyses. This study aimed to assess the outcomes of prehospital patients in relation to their prehospitally measured lactate, pH, and CO2 levels. The primary outcome was 7-day mortality. Methods This register-based cohort study included patients with one or more prehospital blood gas analyses during their prehospital treatment by a physician-manned MECU, from January 2015 to December 2018. The blood samples were analyzed on an ABL90 Flex analyzer. Absolute values with percentages and odds ratios (OR) with 95% confidence intervals (CI) were calculated for the primary and secondary outcomes within prespecified subgroups. Results The study included 745 patients, with an overall 7-day mortality rate of 20.0%. Lactate level The 7-day mortality rates were 11.5% in patients with normal lactate levels ( 7.45, compared to the reference group with normal pH (7.35–7.45). CO2 level The ORs of 7-day mortality rates were 2.54 (95% CI: 1.45–4.46) in patients with blood CO2 of 6.0 kPa, compared to the reference group with normal CO2 (4.3–6.0 kPa). Conclusions This study found a strong correlation between increasing 7-day mortality rates and high blood lactate levels, low levels of pH, and abnormal CO2 blood levels, in prehospital patients undergoing prehospital blood analysis. |
