Application and nursing of precision injection pump in emergency rescue

Emergency patients come with fierce, critical condition, need to increase or decrease the drug dosage at any time according to the change of the condition. The application of precision injection pump reduces the labor intensity of medical staff, can spare more time to observe and monitor the change of condition, and win the opportunity to rescue patients.
1. CPR in progress
During CPR. Various rescue drugs must be injected quickly and accurately, repeatedly injected, and syringes must be changed frequently. Easy to cause pollution, intravenous injection speed is not uniform, the amount is not accurate. Increased the rescue of unsafe factors. Commonly used drugs include epinephrine, sodium bicarbonate, polypamine, norepinephrine, isoproterenol, propofol, anisodamine and so on. During cardiopulmonary resuscitation, the nurse should quickly open 2 venous channels within 3 minutes, the puncture site of the anterior fossa of the elbow is preferred, and the indwelling trocar is placed and administered with a three-way microinjection pump. During cardiopulmonary resuscitation, attention should be paid to: (1) Whether it is safe to place the precision injection pump during the rescue due to the bustle. It can neither affect the patient’s limb movement nor lower than the puncture site to affect the pump speed; (2) When two different drugs are converted, the extension tube should be replaced together; (3) The dosage and pump speed were calculated according to the patient’s body weight ()×3×n as the number of milligrams of a drug contained in 5OrIll lysozyme, where n was the regulatory number. The calculation results were as follows: when n was taken for 1 hour, 1ml/h was injected by precision injection pump equivalent to 0.1ug · kg 1 ·rain; (4) The pump person’s drug record is timely and accurate, and the adjustment of medical orders is consistent with the card on the micro-pump; (5) Strengthen inspection, strictly implement the shift transfer system, so that the instrument operates in good condition.
2. Diabetic ketoacidosis
The main acute cases of diabetes are ketoacidosis and non-ketotic hyperosmolar coma. During rescue, treatment is given to eliminate inducement, replenish fluid, small dose of insulin, correct acidosis, replenish potassium and maintain water and electrolyte balance. Proper control of insulin dosage is the key to treatment. There are some disadvantages of overdose insulin therapy: (1) hypoglycemia; (2) hypokalemia. It can cause arrhythmias and even be life-threatening. (3) Induced cerebral edema and increased mortality; (4) Low blood magnesium, high lacticemia, etc. We used the initial dose of intravenous infusion, then timed and quantitative administration with precision injection pump, measured rapid blood glucose every 1-2h, and adjusted the amount of pancreatic hormone according to the level of blood glucose. When the blood glucose dropped to 13.88 mmol/L, pancreatic hormone was discontinued, and 5% glucose and potassium salt were used at the same time. Potassium salt was properly supplemented according to urine volume and blood glucose was closely observed. The application of precision injection pump continuous intravenous injection of insulin makes the blood sugar drop stable, the urine ketone disappears quickly, and it is not easy to repeat, avoiding the blood sugar too high and too low, and no negative reaction and complications.
3. Hypertension in critical condition
Such as hypertensive crisis, grade III hypertensive cerebral infarction, treatment requires rapid reduction of blood pressure to prevent progressive damage to brain, kidney, heart and other target organs, and can not reduce blood pressure too quickly and too low, resulting in insufficient perfusion of vital organs. If the antihypertensive drug diluted after precision injection pump dose. The dosage can be adjusted according to the blood pressure monitoring to control the blood pressure within the ideal range. The treatment effect of critical hypertension was improved. Reduced complications. Sodium nitroprusside is commonly used as antihypertensive drug, and its precautions are as follows: (1) Replenish blood volume; (2) Calculate the dosage according to the formula, and indicate the drug name, dose, weight, and configuration time on the card of the precision injection pump; (3) Sodium nitroprusside is used to avoid light and prevent drug denaturation. Long-term use of sodium nitroprusside. Blood levels should be checked regularly. Prevention of cyanide poisoning; (4) The drug is currently used and distributed, and takes a single liquid path; (5) The speed should be constant, fast forward is prohibited, and accidental interruption or acceleration is avoided, so as to avoid a sudden drop in blood pressure. The withdrawal of liquid medicine should be gradually reduced to keep the condition stable; (6) Closely observe the changes in the condition. Such as blood pressure peripheral circulation, cough and so on.
4. Acute myocardial infarction
Myocardial infarction is a critical case in emergency medicine. The mortality rate is high, and the patients mainly present with press-like pain in the precardiac area and cannot tolerate it. In addition to timely diagnosis and treatment, adequate analgesia and intravenous thrombolysis are the key to nursing care, and thrombolytic drugs, analgesics and anticoagulant heparin sodium are injected intravenously with precision injection pumps. When using, attention should be paid to: (1) Closely observe the changes in symptoms during the process of medication, especially whether the chest pain is relieved, the number, degree, duration of chest pain attacks, and whether there is an adverse reaction after medication. (2) Observe bleeding: whether there is intracranial bleeding, digestive tract and respiratory tract bleeding. Observe skin, mucosa, gum and injection site for bleeding points. (3) Closely observe the ECG changes, whether there is reinfusion arrhythmia, ECG is performed every 30 minutes within 3 hours after thrombolysis, and a defibrillator is prepared near the bed. The electrode must be in standby state. Coat the electrode plate with a conductive paste. (4) A vein indentation needle pathway was reserved for blood drawing, and blood was drawn every 2h within 12h after thrombolysis to measure the four items of coagulation and myocardial enzymes once. (5) Observe whether there is any allergic reaction, if allergic, immediately stop the drug and intravenous injection of dexamethasone 5-1o, dinium lg or epinephrine], and report to the doctor for emergency treatment.
5. Mental exhaustion
When heart failure occurs, short-term adjuvant use of non-digitalis and positive inotropic drugs, such as oral receptor agonists or phosphodiesterase inhibitors, is required. For example, for chronic heart failure patients with low blood output, high filling pressure and low blood pressure, the oral receptor agonist dopamine and dobutamine can be used, and the conventional dose is 2-1OUg ·kg ~ ·min ~, but these drugs should be administered without breaking and uniformly and continuously during the application period, which is difficult to do with conventional intravenous drip. The application of precision injection pump is the most ideal way of drug delivery.
6 Care and precautions in the use of precision injection pump
(1) Strict aseptic operation. Replace injector, extension tube and scalp needle every 24h, if contaminated at any time. (2) The liquid medicine should be used now and mixed evenly when configured to avoid side effects due to concentration fluctuations. (3) Before pumping into the syringe and extend the bubble in the tube, and send the liquid to the end of the infusion tube to prevent the air from pushing into the blood vessel. (4) Strengthen inspections and timely deal with trace pump alarms. (5) Pay attention to the condition observation. Adjust the speed and concentration according to the change and time of the disease. (6) Some drugs, such as sodium nitroprusside, need to avoid light to avoid changes in property, often using black cloth or tin foil wrapped injector and extension tube.
7. Body meeting
Precision injection pump design strive to achieve high accuracy and easy to use, controlled by the microprocessor, equipped with a warning system, and good anti-leakage performance, will a small amount of liquid precise, uniform, constant, continuous pump in the human body, not affected by liquid viscosity, can be timed to control the amount of drug. Checking the total amount of drugs with time can ensure that the amount of drugs is the most effective to maintain the blood drug concentration, uniform administration, and produce the best efficacy, which plays an important role in emergency rescue, reduces the labor intensity of nurses, improves the quality and efficiency of nursing work, and becomes an essential instrument in emergency rescue work.
