Serum lactate is a potentially valuable biomarker for risk assessment for patients with sepsis, as hyperlactatemia is associated with elevated short-term mortality risks. However, the associations between hyperlactatemia and long-term clinical outcomes in sepsis survivors remain unknown. The objective of this study was to investigate whether hyperlactatemia at the time of hospitalisation for sepsis was associated with worse long-term clinical outcomes in sepsis survivors. In total, of 4983 sepsis survivors aged ≥ 20 years were enrolled in this study between January 1, 2012, and December 31, 2018. They were divided into low (≤18 mg/dL; n = 2698) and high (>18 mg/dL; n = 2285) lactate groups. The high lactate group was then matched 1:1 by propensity-score method to the low lactate group. The outcomes of interest were all-cause mortality, major adverse cardiac events (MACEs), ischaemic stroke, myocardial infarction, hospitalisation for heart failure, and end-stage renal disease. After propensity score matching, the high lactate group had greater risks of all-cause mortality (hazard ratio [HR] 1.54, 95% confidence interval [CI] 1.41–1.67), MACEs (HR 1.53, 95% CI 1.29–1.81), ischaemic stroke (HR 1.47, 95% CI 1.19–1.81), myocardial infarction (HR 1.52, 95% CI 1.17–1.99), and end-stage renal disease (HR 1.42, 95% CI 1.16–1.72). Subgroup analyses stratified by baseline renal function revealed almost similarity across groups. We found that hyperlactatemia is associated with long-term risks of mortality and MACEs in sepsis survivors. Physicians may consider more aggressive and prompter management of sepsis in patients who present with hyperlactatemia to improve long-term prognoses. [ABSTRACT FROM AUTHOR]

Vasopressin has been documented to effectively reduce blood loss in gynecologic practice. However, local infiltration of vasopressin may cause lethal cardiopulmonary complications in spite of rarity of reported cases. Severe bradycardia and cardiac arrest were encountered after intramyometrial injection of vasopressin in our two healthy patients undergoing open uterine myomectomy. We herewith discuss the associated complications and the anesthetic considerations.
