Randomized Controlled TrialCentral Venous-to-Arterial CO2 Difference-Assisted Goal-Directed Hemodynamic Management During Major Surgery-A Randomized Controlled Trial.
Different goals have guided goal-directed therapy (GDT). Protocols aiming for central venous-to-arterial carbon dioxide gap (DCO2) <6 mm Hg have improved organ function in septic shock. Evidence for use of DCO2 in the perioperative period is scarce. We aimed to determine if a GDT protocol using central venous saturation of oxygen (SCvo2) and DCO2 reduced organ dysfunction and intensive care unit (ICU) stay in American Society of Anesthesiologist (ASA) I and II patients undergoing major surgeries compared to pragmatic goal-directed care. ⋯ GDT guided by DCO2 did not improve organ function in our cohort. It resulted in greater use of dobutamine, improved tissue oxygen parameters, and decreased length of ICU stay. More evidence is needed for the routine use of DCO2 in sicker patients. In the absence of cardiac output monitors, it may be a readily available, less-expensive, and underutilized parameter for major surgical procedures.

Observational StudyAssociation Between Preoperative Fibrinogen-to-Albumin Ratio and All-Cause Mortality After Off-Pump Coronary Artery Bypass Grafting: A Retrospective Observational Study.
The fibrinogen-to-albumin ratio (FAR) is a recently introduced prognostic marker for patients with coronary artery disease. The present study investigated whether the FAR is associated with clinical outcome after off-pump coronary artery bypass grafting (OPCAB). ⋯ A higher FAR is associated with increased all-cause mortality after OPCAB. The preoperative FAR could be a prognostic factor for predicting higher mortality after OPCAB.

ReviewIntensive Care in Sub-Saharan Africa: A National Review of the Service Status in Ethiopia.
The burden of critical illness in low-income countries is high and expected to rise. This has implications for wider public health measures including maternal mortality, deaths from communicable diseases, and the global burden of disease related to injury. There is a paucity of data pertaining to the provision of critical care in low-income countries. This study provides a review of critical care services in Ethiopia. ⋯ This study highlights major deficiencies in quantity, distribution, organization, and provision of intensive care in Ethiopia. Improvement efforts led by the Ministry of Health with input from the acute care workforce are an urgent priority.

Regional Anesthesia Associated With Decreased Inpatient and Outpatient Opioid Demand in Tibial Plateau Fracture Surgery.
Regional anesthesia (RA) has been used to reduce pain and opioid usage in elective orthopedic surgery. The hypothesis of this study was that RA would be associated with decreased opioid demand in tibial plateau fracture surgery. ⋯ In tibial plateau fracture surgery, RA was associated with reduced inpatient opioid consumption up to 48 hours postoperatively and reduced outpatient opioid demand up to 90 days postoperatively without an associated risk of acute compartment syndrome. RA should be considered for patients undergoing tibial plateau fracture fixation.

Randomized Controlled TrialEffects of Sevoflurane-Propofol-Balanced Anesthesia on Flash Visual Evoked Potential Monitoring in Spine Surgery: A Randomized Noninferiority Trial.
Intraoperative flash visual evoked potential (FVEP) can be used to monitor visual function during spine surgery. However, it is limited due to the previous perception of its sensitivity to inhalation anesthesia. We conducted this trial to test the noninferiority of sevoflurane-propofol-balanced anesthesia (BA) versus popular propofol-based total intravenous anesthesia (TIVA) on the amplitude of FVEP during spine surgery. ⋯ The effect of 0.5 minimum alveolar concentration (MAC) of sevoflurane-propofol-balanced anesthesia on the P100-N145 amplitude of FVEP was noninferior to that of propofol-based TIVA under comparable BIS range.
