Common knowledge about medication for pain in patients with lymphoma

Lymphoma patients in the late stage will suffer from pain, and many people choose to use painkillers to relieve symptoms. Before taking the medicine, patients should first master the necessary common sense.

1. To treat cancer pain, the first step is to assess the pain, implement step-by-step medication, administer the medication on schedule, and individualize the medication.

2. The dosage of opioids varies greatly among different patients, and there is no ceiling effect. As the dosage increases, the analgesic effect will increase, and the adverse reactions will also increase accordingly. The dosage should be selected according to the patient's tolerance.

3. For any patient with severe pain, regardless of the clinical stage of the tumor and the expected survival time, the maximum tolerated dose of opioid analgesics can be used as long as pain relief treatment is required.

4. Local anesthetics and nerve destroyers are also commonly used for cancer pain, such as lidocaine, ethanol, phenol and hypertonic saline, which can damage certain nerves and relieve pain. It is suitable for patients with advanced cancer who are ineffective in three-step analgesia and have extensive metastatic cancer.

5. Intraventricular administration of drugs has definite efficacy, requires a small amount of medication, and can relieve pain for a long time. It is a new analgesic method. The dose of morphine injected into the ventricular cavity can be started with the minimum dose. As the patient needs it, the amount of analgesic can be gradually increased (but it is best not to exceed 60 mg/day), rather than blindly increasing the drug dosage.
