More indicated for the pregnant woman in cesarean deliveries, the spinal anesthesia, as the name says, is made in the spinal space, that is, where the cerebrospinal fluid circulates. It is through this fluid, or CSF, that substances transport occurs, besides being responsible for cushioning the spinal cord and the cerebral cortex. The injection is unique and accurate, causing immediate motor blockage, but keeping the mother conscious. Understand more about spinal anesthesia with strip-doubts answered by anesthesiologists and obstetricians below:
It hurts? What is the size and thickness of the needle? Understand how the application of spinal
According to the anesthesiologist at the Salt Lake Hospital in São Paulo, Flavia Lopes, spinal anesthesia, better known as rachi, is made deeper in the lumbar spine, with a needle that measures about 12cm and has the width of a thread of hair . “The needle is introduced into the subdural space where the liquor is,” he says. Renato Sá, coordinator of the obstetrics department at the Icaraí Hospital in Rio de Janeiro, explains that the application does not hurt: ” Before the needle is inserted, a local anesthetic is done so that the process is practically painless .”
Understand why the spinal cord is the most indicated at the cesarean section
Immediately, spinal anesthesia has the needle inserted deeper into the lower back and the anesthetic is injected once. With about 3 hours duration, the spindle acts the time necessary for the doctor to perform the cesarean section.
“The pregnant woman loses the sensitivity and movements of the lower limbs. Her action is immediate and the pregnant woman remains conscious and awake, ” says obstetrician and gynecologist Erica Mantelli. According to her, the anesthetic volume used in the epidural can reach 30ml, while in the spinal, it is no more than 2 to 4ml . “There is an application of a much smaller volume than in the epidural, because the spinal cord is a deeper anesthesia,” he says.
At what times is the spinal cord used during normal delivery?
According to the experts, the use of the spinal cord occurs when the pregnant woman arrives at the hospital in advanced labor and with sufficient dilatation. It is during these hours that the woman needs a unique anesthesia and immediate action. “For normal delivery, rachi can be used in smaller doses and in the final stage of labor,” explains the anesthesia Flavia Lopes.
What are the side effects of spinal anesthesia?
After lumbar puncture in the spinal cord, in some cases there may be a decrease in CSF pressure, leading to increased intracranial pressure and headache . “This pain improves when lying down and gets worse when standing or sitting. Treatment consists of rest, hydration and use of analgesics,” explains Erica Mantelli.
According to Renato Sá, headaches are not as common today as they were in the last decade. “The spike needles used today are very thin and hardly cause any more headaches,” he says.
There are still cases of difficulty in breathing. ” The difficulty of breathing can happen. There are two options: the patient reports the difficulty of breathing, but it is only a sensation. Either it effectively presents respiratory distress, which could be avoided by infusing a smaller volume of anesthetic. This complication can be easily remedied, “explains the anesthesiologist at Salt Lake Hospital Flavia Lopes.
