Anesthesia Management for Elderly Patients with Hip Fracture and Respiratory Compromise

Primary Recommendation: Spinal Anesthesia

The American Society of Anesthesiologists recommends spinal anesthesia as the technique of choice for hip fracture repair in elderly patients with respiratory compromise, unless specifically contraindicated 1, 3
Spinal anesthesia avoids airway manipulation and mechanical ventilation, which could exacerbate respiratory issues in patients with respiratory compromise, such as those with "ground-glass" opacities and tachypnea 4
Lower doses of intrathecal bupivacaine (<10 mg) should be used to reduce associated hypotension in elderly patients, with a strength of evidence level of moderate 2, 4

The American College of Cardiology recommends that INR should be <1.5 for neuraxial anesthesia in patients on chronic anticoagulation therapy, with a strength of evidence level of high 5
If INR is elevated, small amounts of vitamin K may be used to reverse the effects of warfarin, with careful monitoring of INR levels 5

The American Society of Regional Anesthesia and Pain Medicine recommends peripheral nerve blockade as an adjunct to spinal anesthesia to extend the period of postoperative non-opioid analgesia, with a strength of evidence level of moderate 1, 2, 3
Femoral nerve or fascia iliaca block is recommended as they are more amenable to ultrasound guidance and reduce the risk of deep hematoma in anticoagulated patients, with a strength of evidence level of moderate 2

The American Society of Anesthesiologists recommends minimal sedation during spinal anesthesia in patients with respiratory compromise, with a strength of evidence level of moderate 2, 3
Avoid opioids as the sole adjunct to anesthesia due to the risk of respiratory depression and postoperative confusion in elderly patients, with a strength of evidence level of high 2, 3

The American Society of Anesthesiologists recommends continuous monitoring, including pulse oximetry, capnography, ECG, and non-invasive blood pressure monitoring, with a strength of evidence level of high 6
Core temperature monitoring is also recommended, with a strength of evidence level of moderate 6

The American Society of Anesthesiologists recommends reduced doses of intravenous induction agents and consideration of inhalational induction to maintain spontaneous ventilation if spinal anesthesia is contraindicated, with a strength of evidence level of moderate 2, 6
Higher inspired oxygen concentrations will likely be required due to the patient's respiratory compromise, with a strength of evidence level of moderate 2

The American Society of Anesthesiologists recommends avoiding simultaneous administration of spinal and general anesthesia as this is associated with precipitous falls in blood pressure, with a strength of evidence level of high 2, 4
Careful management of intraoperative blood pressure is crucial, as hypotension is associated with increased 5- and 30-day mortality, with a strength of evidence level of high 7
