With regard to spinal and epidural (block) anesthesia, nurses should know that:
A high incidence of postbirth headache is seen with spinal blocks. The headaches may be prevented or mitigated to some degree by a number of methods. An autologous epidural blood patch is the most rapid, reliable, and beneficial relief measure for a spinal headache. Spinal blocks may be used for vaginal births, but the woman must be assisted through labor. Epidural blocks limit the woman's ability to move freely. Combined use of spinal and epidural blocks is becoming increasingly popular.
With regard to breathing techniques during labor, maternity nurses should be aware that:
Breathing techniques in the first stage of labor are designed to increase the size of the abdominal cavity to reduce friction. First-stage techniques promote relaxation of abdominal muscles, thereby increasing the size of the abdominal cavity. Instruction in simple breathing and relaxation techniques early in labor is possible and effective. Controlled breathing techniques are most difficult in the transition phase at the end of the first stage of labor, when the cervix is dilated 8 to 10 cm. Patterned-paced breathing can sometimes lead to hyperventilation
A woman is experiencing back labor and complains of intense pain in her lower back. An effective relief measure is to use:
Counterpressure against the sacrum. Counterpressure is steady pressure applied by a support person to the sacral area with the fist or heel of the hand. This technique helps the woman cope with the sensations of internal pressure and pain in the lower back. Pant-blow breathing techniques are usually helpful during contractions per the gate-control theory. Effleurage is light stroking, usually of the abdomen, in rhythm with breathing during contractions. It is used as a distraction from contraction pain but it is unlikely to be effective for back labor. Biofeedback-assisted relaxation techniques are not always successful in reducing labor pain. Using this technique effectively requires strong caregiver support.
With regard to systemic analgesics administered during labor, nurses should be aware that:
Effects on the fetus and newborn can include decreased alertness and delayed sucking. Effects depend on the specific drug given, the dosage, and the timing. Systemic analgesics cross the fetal blood-brain barrier more readily than the maternal blood-brain barrier. IV administration is preferred over IM administration because the drug acts faster and more predictably. PCAs result in decreased use of an analgesic.
In the current practice of childbirth preparation, emphasis is placed on:
Encouraging expectant parents to attend childbirth preparation in any or no specific method. Encouraging expectant parents to attend class is most important, because preparation increases a woman's confidence and thus her ability to cope with labor and birth. The goal is to encourage new parents to attend any one of the acceptable childbirth education programs. Gaining in popularity are Birthing from Within and Hypnobirthing. The Dick-Read method is historically popular and is still in use. The Lamaze method is less focused on a method approach and more concerned with psychologic preparation for labor. Attendance at any available class should be encouraged, however. Bradley as well as other methods encourage women to choose the techniques that work best for them. Women are helped to develop their own birth philosophy and then choose from a variety of skills to help cope with the labor process.
With regard to what might be called the tactile approaches to comfort management, nurses should be aware that:
Hand and foot massage may be especially relaxing in advanced labor, when a woman's tolerance for touch is limited The woman and her partner should experiment with massage before labor to see what might work best. Heat and cold may be applied in an alternating fashion for greater effect. Unlike acupressure, acupuncture, which involves the insertion of thin needles, should be done only by a certified therapist. Therapeutic touch is a laying-on of hands technique that claims to redirect energy fields in the body.
A woman in the active phase of the first stage of labor is using a shallow pattern of breathing, which is about twice the normal adult breathing rate. She starts to complain about feeling lightheaded and dizzy and states that her fingers are tingling. The nurse should:
Help her breathe into a paper bag This client is experiencing the side effects of hyperventilation, which include the symptoms of lightheadedness, dizziness, tingling of the fingers, and circumoral numbness. Notification of the physician is not necessary. The best approach is to have the client breathe into a paper bag held tightly around the nose and mouth to eliminate respiratory alkalosis. The woman can also breathe into her cupped hands if no paper bag is available. Slowing the pace of her breathing will not correct the problem, nor will administration of oxygen. Once the pattern of breathing is corrected, her partner can help the woman maintain her breathing rate with visual, tactile, or auditory cues.
A woman in active labor receives an opioid agonist analgesic. Which medication relieves severe, persistent, or recurrent pain, creates a sense of well-being, overcomes inhibitory factors, and may even relax the cervix but should be used cautiously in women with cardiac disease?
Meperidine (Demerol) Meperidine is the most commonly used opioid agonist analgesic for women in labor throughout the world. It overcomes inhibitory factors in labor and may even relax the cervix. Because tachycardia is a possible adverse reaction, meperidine is used cautiously in women with cardiac disease. Phenergan is an ataractic (tranquilizer) that may be used to augment the desirable effects of the opioid analgesics but has few of those drugs' undesirable effects. Stadol and Nubain are opioid agonist-antagonist analgesics.
After change of shift report, the nurse assumes care of a multiparous client in labor. The woman is complaining of pain that radiates to her abdominal wall, lower back, and buttocks, and down her thighs. Before implementing a plan of care, the nurse should understand that this type of pain is:
Referred As labor progresses the woman often experiences referred pain. It occurs when pain that originates in the uterus radiates to the abdominal wall, the lumbosacral area of the back, the gluteal area, and the thighs. The woman usually has pain only during a contraction and is free from pain between contractions. Visceral pain predominates the first stage of labor. This pain originates from cervical changes, distention of the lower uterine segment, and uterine ischemia. Visceral pain is located over the lower portion of the abdomen. Somatic pain is described as intense, sharp, burning, and well localized. It results from stretching of the perineal tissues and the pelvic floor and occurs during the second stage of labor. Pain experienced during the third stage of labor or afterward during the early postpartum period is uterine. This pain is very similar to that experienced in the first stage of labor.
Nurses should be aware of the difference that experience can make in labor pain, such as:
Sensory pain for nulliparous women often is greater than for multiparous women during early labor. Sensory pain is greater for nulliparous women because their reproductive tract structures are less supple. Affective pain is greater for nulliparous women during the first stage but decreases for both nulliparous and multiparous women during the second stage. Women with a history of substance abuse experience the same amount of pain as those without such a history. Nulliparous women have longer labors and therefore experience more fatigue.
