Carbetocin has been shown to reduce the requirement for additional uterotonics in women exclusively undergoing elective Cesarean delivery (CD). The aim of this review was to determine whether this effect could also be demonstrated in the setting of non-elective CD. ⋯ Carbetocin reduces the need for additional uterotonics in non-elective CD compared with oxytocin. TSA confirmed that this analysis was appropriately powered to detect the pooled estimated effect. Further trials utilizing consistent core outcomes are needed to determine an effect on PPH.

This narrative review critically evaluates the evidence for risk of anemia and red blood cell (RBC) transfusion. For this purpose, it assesses large prospective randomized-controlled trials (RCTs) in medical, surgical, and critical care patient populations in which the impact of specific hemoglobin transfusion thresholds are compared. In these trials, the risks of anemia relative to those of RBC transfusion are assessed. ⋯ The transfusion thresholds recommended by current guidelines vary for medical and surgical patient populations. Guidelines suggesting specific transfusion thresholds for different patient populations should be viewed as a starting point for making an informed decision about RBC transfusion. Alternatives to transfusion (i.e., patient blood management), biomarkers of anemia-induced tissue hypoxia, and transfusion alternatives should continue to be evaluated in large RCTs, with the goal of improving event-free survival in critically ill and perioperative patients.

High acuity units (HAU) are hospital units that provide patients with more acute care and closer monitoring than a general hospital ward but are not as resource intensive as an intensive care unit (ICU). Nevertheless, the impact of opening a HAU on ICU patient outcomes remains poorly defined. We investigated how the creation of a HAU impacted patient outcomes in the ICU. ⋯ These data support the hypothesis that the creation of a HAU may be associated with reduced in-hospital mortality, ICU LOS, and hospital LOS for ICU patients.

Meta Analysis
Quadratus lumborum block for postoperative analgesia: a systematic review and meta-analysis.
The goal of the present systematic review is to determine the efficacy of the quadratus lumborum block (QLB) in providing postoperative analgesia for abdominal wall and hip surgeries when compared with placebo or other analgesic techniques. ⋯ Quadratus lumborum block provided analgesic benefits compared with placebo for use in the abdominal wall and hip surgery, with only marginal benefits compared with other regional analgesic techniques. The identified studies used different variants of QLB in many different surgery types. These findings and conclusions, therefore, should be considered preliminary.
