Effects of Continuous Versus Single Dose Spinal Anesthesia in Octagenerians Undergoing Hip Surgery
Continuous spinal anesthesia (CSA) is an anesthetic technique that offers several clinical advantages for anesthesia and analgesia in elderly patients. The level of sensory blockade can be titrated to the desired dermatomal level with great precision with intrathecal (IT) catheters, allowing better control of the hemodynamic consequences of sympathetic blockade associated with spinal anesthesia compared to epidural or single shot spinal techniques. Better control of hemodynamics maybe advantageous in patients with cardiac disease in whom administration of lower doses of local anesthetics is advantageous. Greater numbers of patients are presenting for surgery with aging-related pre-existing conditions, which places them at greater risk of an adverse outcome, such as cardiac or pulmonary disease or diabetes mellitus. CSA allows incremental dosing of an intrathecal local anesthetic providing fewer hemodynamic alterations. While spinal anesthesia is widely used anesthetic technique in lower limb surgery in the elderly, it induces more hemodynamic instability due to high blockage effect which largely limits the use of conventional dose of spinal anesthesia in high risk elderly patients
