Pain is a certain noxious stimulus that acts on the skin receptors and then turns into nerve impulse signals. It enters the central nervous system along the corresponding sensory nerve afferent pathway, passes through the spinal cord in the central spine of the back, and then uploads to the brain stem and diencephalon of the brain, and then to the brain marginal system and cerebral cortex, which is the senior headquarters of the brain, Pain sensation and pain response will be generated after integration of the headquarters at the following levels. Pain receptors are peripheral nerve endings, widely distributed in human skin, muscles, joints, and abdominal visceral tissues, directly stimulated by pain or indirectly activated by pain-causing factors. The spinal cord in the central spine bone of the back part gathers pain afferent centers from the peripheral skin, efferent nerves from the brain, and pain projection, as well as the local interneurons in the posterior horn of the spinal cord, forming a complex neural network. Like the real network, it is dense, numb, and rich in bioactive substances, receiving, transmitting, and processing pain-afferent information. The brain is the senior center of pain sensation. Except for the olfactory impulse, any sensory afferent signal is integrated into the thalamus in the brain and reaches the cerebral cortex.
How does labor pain come about?
Labor pain may be caused by contractions, parauterine tissues, mental stress and unnecessary muscle tension.
1. Contraction: During childbirth, the baby's own strength is not enough to expand the birth canal. In order to help the baby expand the road and push it forward, the uterine muscles will contract, causing pain. In addition, half a month to one month before delivery, the uterus begins to warm up to prepare for the baby's birth, which is why there will be contractions before delivery.
2. Parauterine tissues: During childbirth, tissues near the uterus (such as pelvic muscles and ligaments that fix the uterus) are squeezed or pulled, which will also cause some pain.
3, mental stress: when nervous, the muscles will not relax, which will prolong the contraction time and aggravate the degree, thus aggravating the labor pain.
4, unnecessary muscle tension: during contractions, pain is easy to unconsciously tighten the muscles of legs, feet, hands, neck and other places, which will cause unnecessary physical exertion and aggravate pain and fatigue.
What else should we do to alleviate the pain?
First, relax. Most pain, especially neuralgia, is caused by fear. However, excessive fear will cause the body to secrete too much adrenal gland, which will aggravate the pain and prolong the time. At the same time, too much fear will lead to muscle tension and poor physical condition. When we need something uncomfortable, we must be prepared and try to overcome fear.
Second, breathe correctly. In case of pain, you can properly carry out deep breathing exercises, inhale deeply through the nose, and then slowly exhale the gas, which can effectively reduce many nerve pain.
Third, apply proper force. When taking deep breaths to help relieve pain. If it aggravates the symptoms of physical discomfort, you can try to clench your fists and see a doctor in time.
Fourth, adjust the posture. According to your own actual situation, before going to the doctor, you can choose a position that suits you to help relieve your body pain, such as lying, standing, or kneeling. If your physical conditions permit, you can get out of bed and walk around properly, which can not only relieve pain but also speed up your metabolism and help you get through difficult times.
Can I take painkillers when I have a baby?
Contraction during childbirth will generally lead to symptoms such as abdominal tightness and stiffness in pregnant women, which will cause severe abdominal pain. If taking analgesics, it will affect the brain development of the fetus, so most women should avoid using analgesics and not blindly use them to avoid harm. During childbirth, it is necessary to closely observe the changes of the fetus. If it is difficult to give birth for a long time and there is severe hypoxia, the fetus can be taken out by cesarean section under the guidance of a doctor to prevent brain damage and mental retardation.
