Greater retrieval in patients ≥60 years may inform dosing considerations; leaves open effects on block quality and safety in prospective trials.
Does advancing age correlate with increased retrieval of local anesthetic solution from the epidural space in patients undergoing epidural anesthesia?
Advancing age (especially ≥60 years) is weakly but positively correlated with an increased volume of local anesthetic solution retrievable from the epidural space.
Watanabe et al. (1997) studied this question.
