Can spinal anesthesia cause high blood pressure?

Can spinal anesthesia cause high blood pressure?

Anesthesia. Undergoing anesthesia can have an effect on your blood pressure. Experts note that the upper airways of some people are sensitive to the placement of a breathing tube. This can activate the heart rate and temporarily increase blood pressure.

Does epidural affect blood pressure?

It’s normal for your blood pressure to fall a little when you have an epidural. Sometimes this can make you feel sick. Your blood pressure will be closely monitored. If necessary, fluids and medicine can be given through a drip to keep your blood pressure normal.

Does a spinal block affect blood pressure?

A fall of blood pressure accompanies each spinal anesthesia. It is the one possible danger associated with this form of anesthesia and may cause death. Its low point is usually ten minutes after the injection, and most fatalities have occurred at that time.

What are the side effects of spinal anesthesia?


  • Allergic reaction to the anesthesia used.
  • Bleeding around the spinal column (hematoma)
  • Difficulty urinating.
  • Drop in blood pressure.
  • Infection in your spine (meningitis or abscess)
  • Nerve damage.
  • Seizures (this is rare)
  • Severe headache.

What are the long term side effects of epidural?

The most frequently reported maternal effects of epidural or spinal analgesia are prolonged symptoms of headache, backache and neurological sequelae. Large retrospective studies of postpartum symptomatology have focused on correlations with regional nerve blockade rather than on other more commonly used analgesics.

Can epidural cause increased heart rate?

Blood pressure and heart rate were not affected by epidural analgesia. However, high-frequency power of heart rate variability increased after epidural (increase in parasympathetic drive).

What causes hypotension after epidural?

A COMMON physiologic effect of epidural and spinal anesthesia is hypotension, primarily due to blockade of the sympathetic nervous system causing arterial and venous vasodilation with subsequent “functional” hypovolemia.

Why does BP drop after epidural?

Low blood pressure An epidural block affects nerve fibers that control muscle contractions inside the blood vessels. This causes the blood vessels to relax, lowering blood pressure.

Why does BP drop after spine?

More than 50% of the patients with T5 or higher levels of anesthesia had a significant decrease in blood pressure. We conclude that the cause of the significant decrease in blood pressure during high spinal anesthesia is in most part due to the blockade of the cardiac sympathetic nerve.

Which of the following is the most serious complication of spinal anesthesia?

Cardiac arrest and perioperative death. Bradycardia and cardiac arrest are the most worrisome complications related to spinal anaesthesia. The incidence of these conditions has been observed to be higher with spinal block in comparison with general anaesthesia.

What causes hypotension after spinal anesthesia?

Hypotension is common during spinal anesthesia (SA) and is caused by a decrease in systemic vascular resistance (SVR) and/or cardiac output (CO). The effect of the dose of bupivacaine administered intrathecally on the changes in CO in elderly patients is largely unknown.
