Blood Pressure and Temperature Management during Anesthesia in Elderly Patients

 

 


According to the summary of the hemodynamic characteristics (pressure type) of elderly patients in many literatures, we can understand its clinical significance including:

Organ perfusion in elderly patients depends on their blood pressure level, so patients who cannot tolerate blood pressure will show a significant drop.

For such patients, if the coexistence of hypertension, diabetes and cerebrovascular disease, their tolerance to hypotension will be worse.


According to the above characteristics, we can summarize the meaning of anesthesia:

The maintenance of peripheral vascular resistance is very important, and intraoperative hypotension is more harmful than hypertension.

In terms of organ perfusion, it is necessary to maintain blood pressure at the preoperative baseline level, which may have serious consequences if it is too high or too low, and the depth of anesthesia should be adjusted appropriately during the maintenance of organ perfusion.

 

On the management of anesthesia period in elderly patients, we know that anesthetic drugs are the key drugs to break the balance of body circulation, and the drop in blood pressure in elderly patients is closely related to the rapid loss of venous volume and vascular tension.

For them, the effects of anesthetics on circulation were more pronounced.

Therefore, while providing real-time general anesthesia for elderly patients, preventive approaches should be based on vasoconstrictor drugs, which can reduce the over-dependence on fluid infusion for hemodynamic balance, thus laying the foundation for the implementation of restrictive fluid management regimens.

 

In addition to paying attention to blood pressure and circulation, Foley catheter temperature probe should be used to monitor the core temperature of elderly patients in real time during perioperative anesthesia to avoid the occurrence of hypothermia.
