The Impact on 30-Day Mortality From a Brief Focused Ultrasound-Guided Management Protocol Immediately Before Emergency Noncardiac Surgery in Critically Ill Patients: A Multicenter Randomized Controlled Trial.

OBJECTIVE: To determine whether brief ultrasound-guided treatment of hemodynamic shock and respiratory failure immediately before emergency noncardiac surgery reduced 30-day mortality. DESIGN: Parallel, nonblinded, randomized trial with 1:1 allocation to control and intervention groups. SETTING: Twenty-eight major hospitals within China. PARTICIPANTS: Six-hundred sixty patients ≥14 years of age, scheduled for emergency noncardiac surgery with evidence of shock (heart rate >120 beat/min, systolic blood pressure< 90 mmHg or requiring inotrope infusion), or respiratory failure (Pulse Oxygen Saturation <92%, respiratory rate >20 beat/min, or requiring mechanical ventilation). INTERVENTIONS: A brief (<15 minutes) focused ultrasound of ventricular filling and function, lung, and peritoneal spaces, with predefined treatment recommendation based on the ultrasound was performed before surgery or standard care. MEASUREMENTS AND MAIN RESULTS: The primary outcome was 30-day mortality. Secondary outcomes included changes in medical or surgical diagnosis and management due to ultrasound, intensive care unit, and hospital stay and cost, and Short Form-8 quality-of-life scores. Although there were frequent changes in diagnosis (82%) and management (49%) after the ultrasound, mortality at 30 days was not different between groups (50 [15.7%] v 53 [16.3%]; odds ratio 1.05, 0.69-1.6, p = 0.826). There were no differences in the secondary outcomes of the days spent in the hospital (mean 13.8 days, 95% confidence interval [CI] 12.1-15.6 v 14.4 d, 11.8-17.1, p = 0.718) or intensive care unit (mean 9.3 days, 95% CI 7.7-11.0 v 8.7 d, 7.2-10.2, p = 0.562), hospital cost (USD$14.5K, 12.2-16.7 v 13.7, 11.5-15.9, p = 0.611) or Short Form-8 scores at one year (mean 80.9, 95% CI 78.4-83.3 v 79.7, 76.9-82.5, p = 0.54) between participants allocated to the ultrasound and control groups. CONCLUSIONS: In critically ill patients with hemodynamic shock or respiratory failure, a focused ultrasound-guided management did not reduce 30-day mortality but led to frequent changes in diagnosis and patient management.

Autologous and Nonautologous Blood Transfusion in Patients with Ruptured Ectopic Pregnancy and Severe Blood Loss.

BACKGROUND: There are some theoretical concerns for the use of intraoperative cell salvage (ICS) in patients with ectopic pregnancy. This study aimed to observe the impact of ICS on the coagulation function and clinical outcomes of patients with ruptured ectopic pregnancy and severe blood loss. METHODS: This was a retrospective study of 225 patients with ruptured ectopic pregnancy and severe blood loss treated at the Third Affiliated Hospital of Guangxi Medical University between January 2012 and May 2016. Patients were grouped according to ICS (n = 116) and controls (n = 109, allogenic transfusion and no transfusion). RESULTS: Compared with controls, patients with ICS had shorter hospitalization (P = 0.007), lower requirement for allogenic blood products (P < 0.001), and higher hemoglobin levels at discharge (P < 0.001). There were no complications/ adverse reactions. In the ICS group, hemoglobin at discharge (-6.5%, P = 0.002) and thrombin time (-3.7%, P = 0.002) were decreased 24 h after surgery, while 24 h APTT was increased (+4.6%, P < 0.001). In the control group, hemoglobin at discharge (-16.8%, P < 0.001) was decreased after surgery and 24 h APTT was increased (+2.4%, P = 0.045). At discharge, hemoglobin levels were higher in the ICS group (P < 0.001). CONCLUSION: ICS was associated with good clinical outcomes in patients with ruptured ectopic pregnancy and severe blood loss.
