Spinal Anesthesia Guidelines
Introduction to Spinal Anesthesia
- The American Society of Anesthesiologists recommends that spinal anesthesia be considered for patients undergoing hip fracture repair, unless contraindicated 2
- The Scottish Intercollegiate Guidelines Network suggests that spinal or epidural anesthesia should be considered for all patients undergoing hip fracture repair unless contraindicated 2
Local Anesthetic Medications
- The European Society of Anesthesiology recommends bupivacaine as the most commonly used long-acting local anesthetic for spinal anesthesia 2
- Lower doses of bupivacaine (less than 10 mg) significantly reduce the risk of hypotension while maintaining adequate anesthesia, according to the American Society of Anesthesiologists 2
Technique and Dosing
- The American Society of Anesthesiologists recommends that hyperbaric (heavy) bupivacaine can be used with specific patient positioning to target the anesthetic to one side or specific surgical area 2
- For hip fracture surgery in elderly patients, positioning the patient laterally with the fractured hip down (inferior) may reduce hypotension, as suggested by the European Society of Anesthesiology 2
Monitoring and Management
- The American Society of Anesthesiologists recommends standard monitoring including continuous pulse oximetry, ECG, and blood pressure for patients undergoing spinal anesthesia 3
- Supplemental oxygen should always be provided during spinal anesthesia, according to the European Society of Anesthesiology 2
Side Effects and Contraindications
- Coagulopathy (bleeding disorders) or anticoagulation are standard contraindications to spinal anesthesia that must be verified before proceeding, as recommended by the American Society of Anesthesiologists 3
- Patient refusal is an absolute contraindication, according to the European Society of Anesthesiology 5
Special Clinical Contexts
- Regional analgesia including spinal techniques should be considered to aid labor management when planned, with ability to extend blockade for operative delivery, as recommended by the American College of Obstetricians and Gynecologists 1
- Spinal anesthesia for cesarean section in younger patients differs conceptually from use in elderly patients requiring different dosing strategies, according to the American Society of Anesthesiologists 2
Discharge Criteria
- Nursing staff should follow strict criteria to enable safe mobilization after spinal anesthesia, including return of sensation to the perianal area (S4-5 nerve roots), plantar flexion of the foot at pre-operative strength levels, and return of proprioception (position sense) in the big toe, as recommended by the American Society of Anesthesiologists 4
- Nurse-led discharge using agreed protocols should be the standard pathway, according to the European Society of Anesthesiology 4
