Midazolam use varied within a nerve block strategy for emergency hip fracture surgery
A matched retrospective study compared nerve blocks with sedation against spinal anesthesia. Outcomes reflect the whole anesthetic strategy, including variable sedative use.

The comparison was between care strategies
Investigators studied emergency hip fracture procedures at one center. The block and sedation approach combined peripheral nerve blocks with sedatives titrated as needed, including midazolam, propofol, or ketamine. Patients receiving planned spinal anesthesia formed the comparison group. The authors used propensity matching to reduce measured differences between groups; clinicians did not randomly assign treatments.
Conversion and recovery answer different questions
The authors reported 98.1% success without conversion for the block and sedation strategy in the main analysis. Four patients converted to general anesthesia and were excluded from perioperative outcome comparisons. Among the analyzed cases, median recovery unit stay was 36 minutes with block and sedation versus 54 minutes with spinal anesthesia. Hypotension requiring inotropes was recorded in 19.4% versus 53.0%, respectively. These comparisons describe the analyzed groups after exclusions.
Why the subgroup matters
In the matched minimally invasive subgroup of 57 cases per group, midazolam, propofol, and ketamine requirements were higher with block and sedation. Recovery unit stay remained shorter and hypotension requiring inotropes remained less frequent. That combination of findings does not attribute either outcome to midazolam: anesthetic technique and several medicines changed together. The retrospective design and potential unmeasured differences remain limitations even after matching. For case review, separate the plan, actual administrations, any conversion, and the recovery outcome rather than treating the label for the technique as a complete medication history.
