Newborns with a subdural hemorrhage may develop problems such as seizures. Epidural hematoma is bleeding between the outer layer dura mater of tissue covering the brain meninges and the skull.
An epidural hematoma may be caused by a skull fracture. If the hematoma increases the pressure in the brain, the soft spots between skull bones fontanelles may bulge. Newborns with an epidural hematoma may have apnea or seizures. Intraventricular hemorrhage is bleeding into the normal fluid-filled spaces ventricles in the brain. Intraparenchymal hemorrhage occurs into the brain tissue itself.
Intraventricular hemorrhages and intraparenchymal hemorrhages usually occur in very premature newborns Premature Newborn A premature newborn is a baby delivered before 37 weeks of gestation. Most of these hemorrhages do not cause symptoms, but large ones may cause apnea or a bluish gray discoloration to the skin, or the newborn's entire body may suddenly stop functioning normally.
Newborns who have large hemorrhages have a poor prognosis, but those with small hemorrhages usually survive and do well. Nerve injuries may occur before or during delivery. These injuries usually cause weakness of the muscles controlled by the affected nerve.
Nerve injuries may involve the. Facial nerve injury is evident when the newborn cries and the face appears lopsided asymmetric. This injury is caused by pressure against the nerve due to.
No treatment of facial nerve injury is needed, and the muscle weakness usually resolves by 2 to 3 months of age. However, sometimes facial nerve weakness is caused by a congenital disorder rather than an injury and does not resolve.
The brachial plexus is a group of large nerves located between the neck and shoulder, leading to each arm. During a difficult delivery, one or both of the baby's arms can be stretched and injure the nerves of the brachial plexus see Plexus Disorders Plexus Disorders Plexuses networks of interwoven nerve fibers from different spinal nerves may be damaged by injury, tumors, pockets of blood hematomas , or autoimmune reactions.
Pain, weakness, and loss Weakness of the shoulder and elbow is called Erb palsy, and weakness of the hand and wrist is called Klumpke palsy. About half of the cases of brachial plexus injuries are related to difficult deliveries, typically involving large babies, and about half occur in babies with normal deliveries.
Brachial plexus injury is less frequent in babies delivered by cesarean delivery. Extreme movements at the shoulder should be avoided to allow the nerves to heal. Many milder injuries resolve over a few days. If the abnormality is more severe or lasts for more than 1 or 2 weeks, physical therapy or occupational therapy for proper positioning and gentle movement of the arm are recommended. The phrenic nerve, which is the nerve going to the diaphragm the muscular wall that separates the organs of the chest from those of the abdomen and assists in breathing , is occasionally damaged, resulting in paralysis of the diaphragm on the same side.
In this case, the newborn may have difficulty breathing and sometimes requires assistance with breathing. Injury of the phrenic nerve usually resolves completely within a few weeks. Spinal cord injuries due to overstretching during delivery are extremely rare. These injuries can result in paralysis below the site of the injury. Damage to the spinal cord is often permanent. Some spinal cord injuries that occur high up in the neck are fatal because they prevent the newborn from breathing properly.
Other nerves, such as the radial nerve in the arm, the sciatic nerve in the lower back, or the obturator nerve in the leg, also may be injured during delivery. In this image of an infant who has Erb palsy, the shoulder is rotated toward the body, the elbow is extended, and the wrist and fingers are flexed.
Sometimes these fractures are not recognized until several days after birth when a lump of tissue forms around the fracture. Clavicle fractures do not seem to bother newborns and need no treatment. Healing is complete over a few weeks. Fractures of the upper arm bone humerus or upper leg bone femur sometimes occur.

For first-time moms, labor often takes between ten and 20 hours. For some women, though, it lasts much longer, while for others it's over much sooner.
Labor generally progresses more quickly for women who've already given birth vaginally. The first stage of labor is the longest stage, especially if you are giving birth for the first time, and can last anywhere from days to a few hours. Early labor usually takes the longest amount of time and transition the shortest. Some caregivers prefer a call sooner, so clarify this ahead of time. Some providers will advise you to stay home as long as possible, especially if you are hoping to have a low-intervention, unmedicated delivery.
The last part of active labor is called the transition period because it marks the shift to the second stage of labor. Transition can take anywhere from a few minutes to a few hours.
It's much more likely to be fast if you've already had a vaginal delivery. If you're laboring without an epidural, this is when you may begin to lose faith in your ability to handle the pain, so you'll need lots of extra encouragement and support from those around you. Once your cervix is fully dilated, the work of the second stage of labor begins: the final descent and birth of your baby. With each contraction, the force of your uterus — combined with the force of your abdominal muscles if you're actively pushing — exerts pressure on your baby to continue to move down through the birth canal.
You may feel a wide range of emotions now: euphoria, awe, pride, disbelief, excitement to name but a few , and, of course, intense relief that it's all over. Exhausted as you may be, you'll also probably feel a burst of energy, and any thoughts of sleep will vanish for the time being.
When pushing, try different positions until you find one that feels right and is effective for you. As the first stage progresses, contractions become more frequent and intense and water eruption occurs. By the end of the first stage, the cervix or uterine opening has been dilated to about four inches [ 2 , 4 ]. This widening allows the baby to move from the uterus to the birth canal vagina.
