cancer cell characteristics, and individual constitution.

Injection of chemotherapy drugs is the most important part of cancer treatment, and it is also the most concerned for patients. Unlike the imagination of many patients, there are very few regulations that must be strictly followed during injection. Before and after treatment and even during infusion, the health and safety of patients are also protected, so patients can feel at ease.

Pre-treatment assessment and blood test

During chemotherapy, the hematopoietic function of the patient's bone marrow will be affected, causing white blood cells, hemoglobin and thrombocytopenia. Therefore, a blood test is required before each chemotherapy; if the report shows that certain indicators are low, treatment may need to be delayed until the indicators return to a safe range.

Preparation before chemotherapy

–If the indicators are ideal, arrange and wait for the treatment date.
–2 to 3 hours before treatment: avoid overeating, avoid indigestible foods, and maintain a light diet, but no need to empty your stomach.
–Take pre-chemotherapy drugs (common anti-vomiting drugs, steroids and gastric drugs) as directed by the doctor to reduce post-treatment discomfort, such as stuffy, nausea and infusion reactions, to ensure patient safety and smooth treatment.

Drug deployment and aseptic operations

–Nursing and pharmaceutical personnel prepare chemotherapy drugs according to the prescription, the time required depends on the type of drug.
-Liquid medicine: After weighing the dose, it is directly extracted with a syringe, which takes a short time.
-Powdered medicine: it needs to be diluted with infusion liquid before extraction, which takes a long time.
–The whole process is completed in the biosafety cabinet to ensure aseptic and personnel safety.

Start the infusion (set the needle and connect the drip)

–Prepare sterile tape and breathable dressing, tie a tourniquet to the suitable injection site, and disinfect with alcohol cotton pads.
–After fixing the skin, push the needle upward on an inclined surface; after blood returns, push in the soft needle and loosen the tourniquet.
–Fix the position relative to the thickness of the soft needle by pressing, extract the hard needle, and connect the infusion tube.
–Depending on individual circumstances, some patients will use artificial blood vessels (mostly for long-term infusion or home treatment, or those with fragile blood vessels).

Feelings and arrangements during infusion

–Injections of steroidal drugs are mostly carried out at a slower speed, and most patients can tolerate discomfort.
–The infusion time varies according to individual prescriptions and drug characteristics, ranging from about half an hour to two hours.
–There is no need to fast during the infusion period, and you can eat a small amount (such as milk and biscuits).
–When you need to go to the toilet, you can press the bell to notify, and the nurse will temporarily remove the hose, and then connect it after completion.

Discomfort treatment and immediate assessment

–If you feel unwell during the infusion, please ring the bell to notify the nurse immediately.
–The nurse will first suspend the infusion and remove the throat, immediately measure the vital signs, and ask the doctor to come for evaluation before deciding on follow-up treatment.

Recommendations for the end of treatment and departure from the hospital

–After the course of treatment is completed, the nurse will remove the throat and press the needle for about 10 minutes to stop bleeding.
–If you are not unwell, you can go home and rest directly; if necessary, you can also rest in the hospital for a while.
–Since allergy prevention drugs may cause dizziness, it is recommended to be accompanied by a family member to leave the hospital and avoid driving or operating machinery by yourself.
–Most patients have no obvious discomfort on the same day, but tiredness may appear after 1 to 3 days; it is recommended to rest at home, drink plenty of water and eat a balanced diet to prepare for the next injection.
