What do you know about vital signs of anaesthesia?
The monitoring of vital signs in anaesthesia is a key element in ensuring the safety of patients during surgery. Changes in vital signs can reflect changes in the physical state of the patient, and it is therefore essential that indicators such as heart rate, blood pressure, respiratory frequency and body temperature are effectively monitored during anaesthesia. This paper will explore how the vital signs of patients are monitored in anaesthesia, including the need for monitoring, monitoring methods, monitoring objectives and concerns.
1. The need for vital signs monitoring during anaesthesia may be influenced by anaesthesia, surgery and other factors. 1. Timely detection of problems: real-time monitoring allows for rapid identification of potential crises such as cardiac disorders, low blood pressure, air embolism, etc., for timely intervention.
2. Assessment of the depth of anaesthesia: the depth of anaesthesia directly affects the vital signs of the patient, and monitoring of these indicators can help an anaesthetists to determine whether anaesthesia is appropriate and whether the dose of anaesthesia needs to be adjusted. 3. Providing the necessary data support: Continuous recording of life signs of patients during the operation and providing valuable data for post-operative assessment and any possible complications.
Main vital signs and monitoring methods
Heart Rate
– Methodologies for monitoring: The ECG is the gold standard for monitoring the heart rate. The ECG can show the electron activity of the heart in real time and help to identify heart disorders.
– Target range: normal static heart rate of adults 60-100 per minute. Monitoring requires attention to changes in the heart rate, which can be too rapid or too slow. Blood pressure
– Methodologies for monitoring: Blood pressure monitoring can be done by a non-start (e.g. cuffband sphygmomanometers) or by a start (e.g., arterial catheter monitoring). Innovative monitoring provides more real-time and accurate data, especially in high-risk operations.
– Target range: Normal adult blood pressure is 120/80 mmHg. Real-time monitoring of blood pressure fluctuations allows for timely detection of low blood pressure, haemorrhage, etc. Respiratory frequency (Respiratory Late)
– Monitoring methods: Respiration frequency can be measured by observing the patient ‘ s breathing or using respiratory monitoring instruments. Pulse blood oxy is not only a measure of blood oxygen saturation, but also, to some extent, of respiratory frequency.
– Target range: Normal adult breathing frequency 12-20 per minute. A sudden increase or decrease in the frequency of breathing may indicate respiratory blockage, overdose, etc. 4. Blood O2 saturation (SpO2)
– Methodologies: The use of pulse Oximeter allows non-intrusive monitoring of blood oxygen saturation.
– Target range: Normal blood oxygen saturation should be above 95% and less than 90% may indicate oxygen deficiency and need to be addressed immediately. 5. Temperature
– Methodologies for monitoring: An electron thermometer can be used to measure body temperature under armpit, mouth or rectal. During the operation, especially during long periods of operation, monitoring using a cuisine temperature probe can more accurately reflect core temperature.
– Target range: Normal body temperature is about 36.5-37.5°C. In the course of anaesthesia, care is taken to maintain normal body temperature to prevent low temperature in the operation.
1. Preparation of equipment: To ensure that all monitoring equipment is functional, battery sufficient, connected and stable and familiar with the operation of the equipment. 2. Basic assessment: a comprehensive assessment of the patient before anaesthesia, including his or her medical history, past medical history and medical findings, with a view to developing an appropriate monitoring plan. 3. Articular monitoring: Life signs are continuously monitored after anaesthesia begins, data are recorded and narcotic drugs are adjusted as appropriate. 4. Data recording: To record changes in vital signs in real time for detailed analysis and assessment after the operation.
Note: Individualized monitoring: the biological state and needs of different patients vary, and individualized monitoring programmes are required in accordance with the specific circumstances of the patient. Ongoing monitoring: Monitoring cannot be interrupted during anaesthesia. Even during the non-surgery phase, vital signs monitoring should be continued to respond to any sudden onset. 3. Teamwork: There is a need for good communication between anaesthetists, surgeons and caregivers to ensure information sharing in order to address in a timely manner the issues identified in the monitoring. 4. Emergency preparedness: There should be a capacity to respond to a variety of contingencies, such as cardiac arrest, allergies, etc., and ready to provide the necessary treatment equipment and drugs.
The conclusion is that the vital signs of the patient during anaesthesia are the basis for ensuring the safety of the operation. Timely and effective monitoring allows for the rapid identification and management of potential crises and the safety of patients. As technology progresses, future vital signs monitoring will become more accurate and efficient, providing better anaesthesia experience and better safety for patients.
