Hypertension Treatment

Some Anaesthesia Options for Hypertensive Patients

Anaesthesia is the absence of sensation. It is used to prevent pain and discomfort during surgeries and operations. There are different kinds of anaesthesia, namely sedation, local anaesthesia, regional anaesthesia, general anaesthesia, epidural anaesthesia, and spinal anaesthesia.

Sedation involves the use of medication that makes a patient drowsy and completely asleep. It can also be used during surgery as a regional anaesthesia to help the patient to relax and feel at ease.

In the case of local anaesthesia, a local anaesthetic is put around the affected region to make it free from the sensation of pain. This type of anaesthesia is used when only a small area needs to be anaesthetized. It involves a simple induction process using injections.

Regional anaesthesia involves the blockage of the nerve supply to a particular part of the body. Some examples of this type of anaesthesia include, among others, surgery on the hand, arm, leg, foot, gynecological surgery, caesarean section, and childbirth.

General anaesthesia is used in case of major surgical operations that require long periods of unconsciousness. In this, the entire body, including the brain, is anaesthetized.

Epidural anaesthesia uses large volume of anaesthetic, far away from the spinal cord. Spinal anaesthesia involves anaesthetizing the lower region of the body, below the spinal cord. It is used in cases when surgery needs to be performed on the hip, knee, leg, and foot or for a C-section operation.

The anaesthesist decides the best anaesthesia for high blood pressure patients. This decision is based on the patient’s needs and his/her medical history. The options are discussed before the actual surgery is performed. The final decision about the most suitable anaesthesia depends on the patient, surgeon, anesthetist, and the kind of surgery to be performed.

Post operation, some patients may develop high blood pressure due to stress, anxiety or pain. Many people may feel baffled and confused after anaesthesia. Such an after-effect can cause a further deterioration of the existing high blood pressure levels.

Thus, it becomes rather important to assess the medical history of the patient and determine the underlying cause for hypertension. Based on the findings, the anaesthesist may be able to decide on the best anaesthesia for high blood pressure patients.

Regional anaesthesia may be a good choice for the patients with a history of uncontrolled high blood pressure. Persons suffering from “white coat” hypertension are not at any greater risk from anaesthesia, and thus, in such cases, there may not be any need to delay the surgery.

Elderly patients, with systolic blood pressure reading less than 180/190mmHg, can also be considered fit candidates to undergo surgery using anaesthesia.

Spinal and epidural anaesthesia may increase hypotension in hypertensive patients who are under the influence of vasoldilator drugs or are dehydrated. Both these types of anaesthesia can lead to arterial hypotension in patients with inadequately treated levels of high blood pressure.

As epidural anaesthesia involves use of large doses of anaesthetics, it may lead to serious complications in some hypertensive patients.

A thorough assessment of the patient’s medical background and needs is vital to determine the most suitable form of anaesthesia for him/her. Such an evaluation is significant, as it may help the physician decide on the need for a waiting period or the use of hypertensive drugs.

Best anaesthesia for high blood pressure patients may differ from person to person, on the basis of his/her health history, and the need for the surgery.
