A TYPICAL POST-POLIO PATIENT:
• Anxious about having anesthesia
• Obese
• Paralysis of extremities, contractures
• Pharyngeal and laryngeal weakness
• May have ventilatory muscle weakness
• Autonomic dysfunction, including reflux
• Sensitive to anesthetics (?), muscle relaxants
• Has a lot of postop pain

THE PLANNED OPERATION
• Certain surgeries need a certain kind of
anesthesia
• Certain surgeries can be done with just sedation
and don’t need general anesthesia
• The position needed for the surgery
• Different surgeons do things differently

TYPES OF ANESTHESIA
• GENERAL : Asleep
• REGIONAL : Only part of the body
• MAC : Monitored Anesthesia Care
Surgeon gives local anesthesia
We sedate and monitor

GENERAL ANESTHESIA
• Can induce lung injury in healthy lungs
• “Protective strategies” still result in Acute
Lung Injury (ALI)
• 90% of all patients with G/A get atelectasis
postop

• THIS IS GOOD!

HAVE A SPINAL OR EPIDURAL
ANESTHETIC ?

WHAT SHOULD YOU DO WHEN
SURGERY IS PLANNED ?
• See your pulmonary MD
• Get pulmonary function tests!!!!
• Talk with your surgeon about your polio
situation
• Learn more about the operation: what are
the possible complications
![Page 19: ANESTHESIA FOR POST-POLIO PATIENTSpolioconference.com/2011/Powerpoint presentations/pdf/thursday/Selma... · OBJECTIVES •What’s the best anesthesia for you? –Little supporting](https://reader033.vdocuments.us/reader033/viewer/2022041414/5e1a3289ba346f4caf6af224/html5/thumbnails/19.jpg)
WHAT SHOULD YOU DO WHEN
SURGERY IS PLANNED ?
• Are you at high risk for postop respiratory failure?
Used an iron lung
Use a ventilator now
• Do you have sleep apnea or scoliosis?
• Most difficult risk for post-polio is postop respiratory
failure
• Your pulmonary MD must be involved preop and postop

WHAT SHOULD YOU DO WHEN
SURGERY IS PLANNED ?
• Work on improving pulmonary function
preop!
Stop smoking 3-4 weeks before surgery
Bronchodilator meds
Antibiotics, if infection is present
Chest physiotherapy/bronchial drainage
Plan for the postop period

POSTOP CARE
Will you need a ventilator postop? Type?
Who will manage it?
Take your most recent pulmonary records when you come to the hospital
Sleep apnea patients on CPAP/BiPAP should bring their machine to the hospital
Postop pain management! Injected local anesthesia at surgery
Anesthesiologist-managed epidural/intrathecal narcotics
Patient-controlled analgesia (PCA): Possible problems

CHANGES!
• Surgery is much less invasive
• Anesthesia is rapidly changing:
– Anesthesia is much safer!
– Have better drugs
– Know a lot more about what happens during
anesthesia
