Total hip arthroplasty is a common procedure being performed at an increasing rate in the United States. Recovering from this surgery to the extent that one can participate in criteria for discharge relies heavily on effective postoperative analgesia. Many regional anesthetic techniques are deployed in this realm. The recent utilization of quadratus lumborum (QL) blocks with success in other procedures warrants investigation in the hip arthroplasty population. ⋯ QL block employment in hip surgery produces significant reduction in length of stay and intraoperative fentanyl use. While quadratus lumborum blocks are rapidly becoming a popular option due to its quality and spread of analgesia, more adequately powered prospective research must be performed to appropriately elucidate significant trends.

Postoperative cognitive dysfunction (POCD) is commonly observed following cardiac surgery. The utilization of cardiopulmonary bypass (CPB) is associated with many possible mechanisms to cause POCD. However, there is no evidence confirming that CPB alone is the cause of POCD. ⋯ Durations of CPB, cross clamp, diabetes, and educational level were not the main risks of POCD. Old age was a significant predictor to POCD.
