Core Tip
Core Tip: We found that ultrasound (US) guided femoral nerve block (FNB) is a safe and effective method to assist in pain management prior to surgery in hip fractures. This method is beneficial in decreasing the risk of morbidity in hip fracture patients as seen in lower rates of rehospitalizations and decreased mortality. We have learned that US guided FNB led to statistically significant lower pain levels prior to surgery compared with the group that received standard analgesia. We have learned that US guided FNB resulted in a statistically significant decrease in the risk of morbidity, specifically a decrease in rehospitalization and mortality 6 months post-surgery. In the future we need to continue to research this area regarding the issue of Being able to ascertain if delirium is decreased in patients undergoing US guided FNB for pain management and if patients had a reduced need for opioids.
