Cervical cancer, chemotherapy toxicity and nursing
1, chemotherapy
Chemotherapy is systemic treatment, for the treatment of advanced
cases. Ever, that the efficacy of chemotherapy for cervical cancer is
not ideal to ease the rate is low, a short remission. For the
terminally ill, they can only play a relieve suffering, and prolong
life palliative role. In recent years, with the constant introduction
of new anti-cancer drugs, routes of administration of the improvements,
the joint application of multiple drugs in the treatment of cervical
cancer, chemotherapy has become an effective adjuvant treatment, can be
used in advanced cases or in connection with surgery, radiotherapy
combination can also be used to treat recurrent cancer. Chemical drugs
can act directly on cancer, some drugs can enhance the biological
effects of radiation therapy.
' Single-drug treatment: before chemotherapy for cervical cancer
multi-purpose single-drug treatment, commonly used drugs such as
nitrogen mustard, bleomycin, mitomycin C ,5-FU and so on. Application
discovered in recent years the efficacy of cisplatin in the treatment
of cervical cancer is better than the other drugs.
' combined treatment: combination therapy generally based on drug
mechanism of action, the role of points and toxicity of drugs to choose
more than two kinds of drug treatment. Many of the programs combined
chemotherapy of cervical cancer, of which cis-platinum and
bleomycin-based chemotherapy regimen better effect. Commonly used
programs such as cisplatin + bleomycin + vincristine, cisplatin +
bleomycin + doxorubicin. Combined with adriamycin-based programs are
adriamycin + methotrexate.
' chemotherapy and radiation combined treatment: chemotherapy
combined with radiotherapy may increase the therapeutic effect of
advanced cervical cancer. Its application method can be chemotherapy
before radiotherapy, chemotherapy and radiotherapy at the same time
applications, such as after radiotherapy plus chemotherapy.
' Comprehensive chemotherapy and surgical treatment: application
of methods of preoperative chemotherapy and postoperative chemotherapy.
' intraarterial regional chemotherapy: general cervical cancer is
a systemic route of administration of chemotherapy intravenous
medication, arterial regional chemotherapy in recent years the
development of a chemotherapy through the abdominal wall to the iliac
artery common iliac artery was inserted into arterial levels of
infusion. Commonly used drugs 5-FU, ammonia mustard, bleomycin,
cisplatin, doxorubicin and so on.
Ammonia mustard generally the first choice.
Second, the major toxicity of chemotherapy
2.1 digestive toxicity of many anti-cancer drugs can cause varying
degrees of digestive response, generally appeared earlier than the bone
marrow suppression. Clinically visible oral ulcers and gastrointestinal
mucosa, there anorexia, nausea, vomiting, abdominal pain, diarrhea,
severe, causing gastrointestinal bleeding, intestinal obstruction and
intestinal necrosis. Nausea and vomiting is a common gastrointestinal
reactions, persistent nausea and vomiting can cause repeated in
patients with mental stress, fear: anxiety, appetite reduction, weight
loss, electrolyte imbalance, and even patient refused medication,
affecting drug efficacy.
2.2 The majority of bone marrow suppression caused by chemotherapy
drugs can be varying degrees of bone marrow suppression, manifested as
leukopenia, of which the most obvious decline in granulocytes. As the
dose increases, platelets and red blood cells can also be reduced, in
severe cases can reduce hemoglobin.
2.3 urinary system toxicity of many chemotherapy drugs in the
liver metabolism, metabolites can cause kidney damage, kidney
dysfunction, proteinuria, hematuria, severe cases can be oliguria,
anuria, and even life-threatening. Chemotherapy should pay attention to
monitoring by the renal function, adequate hydration. Taking
combination therapy and the use of diuretics, nurses should pay
attention to record urine output to maintain urine output> 100mL / h
or 24 hours of not less than 2000mL. Encourage patients to a large
number of drinking water, to drink more green tea, water or clothing
diuretic Tonglin Chinese medicine, dilute urine, to reduce the urinary
system toxicity.
2.4 cardiovascular system toxicity of some chemotherapeutic drugs
on the cardiovascular system of toxic side-effects, such as the
alkylating agent can cause high blood pressure, heart rate increased
and fast, adriamycin (ADb1) barriers to enable the local vessel wall
occurs, but also bow ! from cardiac disease, manifested as heart
failure, arrhythmia and so on. Therefore, the medication before and
drug use should be to observe the patient's heart and found that
abnormal immediate withdrawal, timely treatment. Change to have heart
disease should avoid the use of cardiac toxic effects of chemotherapy
drugs.
2.5 nervous system toxicity of the more common for the DDP,
ifosfamide (IFO) can occur after treatment such as paresthesia, mental
confusion, headache, lethargy, body ache, and other neurological reflex
weakening is still a lack of effective treatment for toxic should be
withdrawal observation, nutritional support, application Vit and may
contribute to vasodilator nerve function recovery. For the physical
activity or sensory abnormalities may provide a passive activity,
massage.
Third, care of patients with cervical cancer chemotherapy
3.1 Psychological care nurses should listen to patients complain
of their fears, discomfort and pain, care for them, in order to obtain
the trust. Providing them with needed assistance to enable them to
understand the role of chemotherapy drugs, adverse reactions,
medication when the attention, to encourage interaction among sufferers
to introduce the successful cases, so that cheerful mind, emotional
stability, and foster confidence in disease-fighting and do a good job
families, so that patients and their families able to cope with the
treatment.
3.2 intravenous care for the full effect of chemotherapy,
medication, said before you get an accurate body weight (preferably in
the morning, fasting, they gain weight after row 2). According to
doctor's advice seriously seven pairs of three investigations, the
correct dissolved and diluted drugs and are now done with the concept
of distribution, when the combination therapy according to the nature
of the drug, discharge the order, and some see the light of drug
decomposition, should pay attention to dark. Puncture technique to
improve and protect the vein, there are plans to start using from the
remote right and left turn choose a suitable vein, do not puncture
within 24 hours before the bottom of the vein puncture once again to
prevent leaking. Conditions of the patients or the hospital may make
use of catheter use. Lost when the first intravenous saline and
confirmed that the needle be in the administration of intravascular
transfusion medicine blood vessel wall and then washed with saline to
reduce wall stimulation; needle injection, when attention to the
protection veins, press 3 ~ 5 minute infusion, strengthening
observation, master Disu to prevent liquid leakage. If liquid
inadvertently omitted in the skin should immediately stop liquid input,
then to retain the needle syringe, withdraw sword skin of the liquid
can then be injected into the skin antidote.
3.3 The toxicity of chemotherapy drugs on the hematopoietic system
of care in nursing toxicity strictly controlled indications, the
general poor condition, recently done radiotherapy or chemotherapy
should be used with caution in patients or reduce the dose of
medication can be the necessary support during the treatment of , such
as increased nutrition, for righting, Bu Zhong Yi Qi Chinese medicine
and vitamins such as white blood cell count regularly checked by your
doctor. Pairs of normal white blood cell counts in patients to prevent
infection, reduce or decline to visit, live in single room, regular air
disinfection. Use of antibiotics by your doctor, application l white
blood drugs, a small number enter the new blood component transfusion
or given to observe the changes in vital signs, observe whether the
bleeding tendency in patients to avoid the use of aspirin until the
drugs, intravenous infusion needle injection pressure when five
minutes. For the loss of appetite, loss of appetite in patients, first
of all to enable patients to understand the importance of nutrition.
Zhu Huanzhe eat sweets, try to eat greasy, fried food, you can
Shaoliangduocan, eating digestible, nutrient-rich diet. For severe
cases, nausea and vomiting can be 30-60 minutes before chemotherapy and
chemotherapy given after the 4-6 hours of antiemetic drugs. For
abdominal pain, diarrhea, patients should pay attention to observe the
nature of abdominal pain, stool characteristics, frequency, and timely
submission Zhu Huanzhe eat soft, low residue, low fiber, non-irritating
food. If the three days is not defecation, shall be used laxatives.
Oral ulcers are generally more severe impact of pain in patients with
swallowing eating, you can pre-meal with 0.5% tetracaine plus
Gentamicin cable coating, eating bogey spicy, hot, cold, hard,
over-stimulate the rough, and alcohol and tobacco. May be granted the
same with the temperature of the liquid without stimulation, soft food,
serious oral care and balanced nutrition to help heal ulcers caused by
chemotherapy mucosal swelling of the throat or esophagus and cause pain
and even difficulty swallowing, shall be encouraged to talk too much ,
ground water, promote pharyngeal activity, reduce congestion and edema
caused by pharyngeal ulcer.
