A Case Study in the Undertreatment of Surgical Pain
/By Dr. Stefan Franzen
“Patient Z” is a close family member who has an incurable form of arthritis known as ankylosing spondylitis. His back is partially fused and his large joints are so damaged that they all need replacement. Each step he takes, even with a walker using his arms as the main support, is exceedingly painful. Just getting into a car to go to a doctor’s office is excruciating.
Several years ago, Patient Z went through an opioid rotation from morphine/oxycodone to buprenorphine. This was a forced choice. His pain clinic told him that they would make a final push to taper him to a daily dose of 120 MME (morphine milligram equivalents). That was the statewide cap on prescribing. Patient Z had reduced gradually for years to accommodate them, but when the dose fell below 180 MME, he felt miserable much of the time.
Patient Z transferred to a pain institute where he was prescribed pure buprenorphine for pain. The doctors at the institute had conducted clinical studies and found buprenorphine to be as effective as morphine. When Patient Z reached the maximum daily dose of buprenorphine in sublingual form, he felt relief.
Patient Z might never have chosen buprenorphine, but he found that it managed his pain on most days. In his experience, the dose was as effective as 200 MME of morphine and oxycodone. But pain flares can overwhelm even that dose.
A surgeon urged surgery because stenosis and deformation of the neck caused by ankylosing spondylitis could lead to paralysis. Realizing that he was losing sensation in his arms and hands, Patient Z scheduled the surgery.
At the pre-op, he was told that the surgery required an incision in the front and back of his neck. The surgeon would implant a metal brace that was about 5 cm long. Patient Z asked the surgeon’s nurse about pain management and she assured him that he would be comfortable in the hospital.
He also asked his pain clinic what they would do to help with post-operative pain. They told him to rely on hospital care. Patient Z knew the constraints on the pain clinic and did not push the point. When he arrived for surgery, he still did not know what was planned for post-surgical pain control.
‘My Pain Level is 10’
The surgery was successful. Patient Z woke up in a hospital bed with a neck brace. But he could not move. After a few hours the pain set in. He could not believe that pain could be so all-consuming. Even lying motionless in bed, his body throbbed with pain radiating out from the back of his neck. He felt like he was nailed to the bed.
The nurses were told not to give him buprenorphine on the first night. One nurse said he was afraid that Patient Z would suffer respiratory depression. At first, they only gave him acetaminophen and pregabalin.
In the middle of the night, Patient Z called the nurse and said something he never thought he would say: “My pain level is 10.”
The nurse left to contact the doctor in charge. An hour passed. It seemed like an eternity to Patient Z, who was in agony. Finally, the nurse returned with a muscle relaxant and a two-milligram hydromorphone pill. That is the equivalent of 8-10 milligrams of oral morphine.
Patient Z knew how low this dose was, but he swallowed the pill and hoped the pain would stop. It did not. Patient Z is stoic and had suffered from extreme pain in the past, but he had to speak up. The pain was truly unbearable. His collapsed hips were throbbing. Pain was shooting down his arms and legs. Any movement brought on involuntary spasms.
Finally, at 5 am, a nurse gave Patient Z a two-milligram injection of hydromorphone. The pain abated and he could finally rest. This dynamic of denial and waiting until Patient Z was nauseous from pain before providing relief continued for three more days. Nurses rotated in and out, and the doctors made decisions that left him miserable most of the time.
On the fourth day after surgery, Patient Z was released from the hospital. Patient Z asked what he should do to control the pain. The surgeon looked unhappy. He said that the pain of surgery should pass within a week and Patient Z had already received ample pain medication. Other pain was not the surgeon’s concern, and he was told to consult with his pain physician.
By this time, one of the nurses who had seen Patient Z several times came to understand how debilitating his pain was. The nurse told Patient Z that she had observed many recovering surgery patients. She said that neck operations with an incision from the back is one of the most painful.
Patient Z was lucky that people could see his struggle with pain. Many patients have pain that is not recognized. Even so, the nurse told him that they could not write a prescription for opioid pain medication. Someone must have decided that Patient Z really did have unmet pain needs.
Maybe the nurse advocated for him because, as Patient Z was being released the nurse unexpectedly gave him a vial of pain medication. She said that it would be enough to keep him comfortable until the neck pain subsided. When Patient Z arrived home and looked at the vial, he saw that the oral hydromorphone dose was 12 milligrams daily, the equivalent of approximately 50 MME. And he only had a six-day supply.
This was not nearly enough to give Patient Z relief from the neck pain, back pain, hip pain and systemic inflammatory pain. To make matters worse, the instructions stated that he should not take buprenorphine for the six days he was on hydromorphone.
After one day, Patient Z’s misery escalated because he was going through withdrawal while also recovering from neck surgery. After two days, Patient Z resumed taking buprenorphine and stopped taking hydromorphone. At least the buprenorphine gave him partial relief.
Few patients take buprenorphine for pain in the U.S. It has been reported that hydromorphone is compatible with buprenorphine in post-surgical pain management. Yet doctors and nurses appeared unfamiliar with buprenorphine, which is also used to treat opioid addiction when combined with naloxone. Their comments in the hospital showed that they did not understand that buprenorphine is safer than other opioids and can also be used to treat pain.
The combination of misunderstanding buprenorphine and the current practice of giving as little pain medication as possible put a severely ill patient through an unnecessary ordeal. Today, most medical education and pain research is solely aimed at reducing or eliminating opioids, rather than using buprenorphine and other alternative opioids to provide at least some relief.
Buprenorphine is slow-acting and therefore not the ideal medication for acute pain. But studies have shown that it can be combined with other opioids to provide relief. For some types of pain, there is no substitute for opioid pain medication.
