Final answer:
Age-related changes to consider when performing neuraxial block include decreased clearance of drugs in older adults and changes in spine elasticity and rigidity.
Step-by-step explanation:
When performing neuraxial block, there are several age-related changes to consider. These changes can affect the pharmacokinetics and pharmacodynamics of drugs used in the procedure.
One important consideration is the decreased clearance of local anesthetics in older adults. This means that the drugs may remain in the body for longer periods of time, increasing the risk of toxicity.
Another change is the decreased elasticity and increased rigidity of the spine in older individuals. This can make it more challenging to perform the procedure and may require adjustments in technique.
