Recently, we received a patient surnamed Zhang who attempted suicide with prostate cancer with multiple bone metastases combined with severe cancer pain! According to his family, Mr. Zhang needed to take a large amount of oral morphine slow-release tablets every day, but he still could not relieve his cancer pain. He could not sleep every night due to the pain, and his family members had to take turns to guard him every day in order to prevent him from committing suicide! In response to Mr. Zhang’s condition, the pain management team performed an implantation of an intrathecal infusion system for him. After the operation, Mr. Zhang felt like a newborn and said happily, “I can finally sleep through the night, and I don’t have to suffer from the pain of cancer any more.” . According to WHO statistics, there are at least tens of millions of cancer patients suffering from cancer pain every day. Commonly used oral painkillers have high dosage, many adverse reactions and poor effects. Cancer pain seriously affects the quality of life of cancer patients and their confidence in resisting tumors, depletes their energy and rapidly reduces their immunity to tumor cells. The implantation technology of intrathecal infusion system not only avoids the adverse reactions such as nausea and vomiting, constipation, drowsiness, and respiratory depression of oral medication, but also adjusts the output of medication according to the patient’s degree of pain and the pattern of pain onset, maximally meets the analgesic needs of different patients, and significantly improves the quality of life of cancer pain patients. If you have relatives or friends around you who are suffering from cancer pain, please go to the pain department immediately.
