Risk of preeclampsia rises to 25% if the if focal neurologic signs, such as unilateral pupil dila index pregnancy was complicated by severe pre-eclampsia, tion, are present. The prognosis is very poor, and recovery is the 34 weeks, and about 1 in 2 (55%) pregnancies if it led to birth exception rather than the rule. A Cohort study in Scotland indicated that women who develop gestational hypertension and preeclampsia are at higher risk of developing chronic hypertension and dying from stroke than Visual Disorders 74 those who remain normotensive during pregnancy. However, Blindness may occur in patients with severe preeclampsia women who develop preeclampsia are not at high risk of devel and eclampsia and may persist for several days, although oping hypertension when using oral contraception.

Cortical blindness is equivalent to a seizure, coronary artery disease and stroke. Such patients must be and patients with these symptoms should be treated as counseled on lifestyle and risk factor modifcation to alter having eclampsia. Papilloedema in preeclampsia is into high risk group so that surveillance can be intensifed highly unusual and demands a reevaluation to rule out the and prophylactic therapies can be initiated. Diplopia have been proposed to identify women at risk of developing is a symptom that may occur, and it is caused by functional preeclampsia. Like most lesions caused by preeclampsia, sixth nerve abnormalities that have been found in association with pre paralysis improves after delivery and eventually disappears eclampsia.

Sensitivities of all these tests range from 55 Patients with preeclampsia have elevated levels of plasma to 70% with specifcities of approximately 85%.

There are Angiotensin Sensitivity Test studies indicating that increased plasma level of endothelium the abnormal vascular reactivity of patients destined to originated fbronectin precede the clinical signs of pre develop preeclampsia may be detected several weeks be eclampsia and may be useful for prediction of the disease. Unfortunately, this test is labour intensive and has a high incidence of the underlying mechanism for the development of pre false negative and false positive results. Uterine artery Doppler velo the roll-over test was originally described as a noninvasive cimetry at 22–24 weeks is useful to identify women destined offce procedure having an excellent correlation with the to develop preeclampsia. It measures the or the presence of early diastolic notching (unilateral or bilat hypertensive response in women at 28 to 32 weeks who are eral).

The decision to discount 5ml trusopt with visa use Intrapartum and Postpartum Care of the Mother 183 parenteral agents to generic trusopt 5 ml with visa manage labor pain should be made in collaboration with the patient after a careful discussion of the risks and benefits 5 ml trusopt. Although regional anal gesia provides superior pain relief buy 5 ml trusopt with amex, some women are satisfied with the level of analgesia provided by narcotics when adequate doses are used. High doses potentially are depressing to the woman, fetus, and particu larly the newborn immediately after delivery. There has been some concern about fetal safety with the use of nalbuphine hydrochloride; however, there is insufficient evidence at this time to recommend a change in practice with the use of this medication. In addition, a vary ing degree of motor blockade may be present, depending on the agents used. Data indicate that low-dose neuraxial analgesia adminis tered in early labor does not increase the rate of cesarean delivery and some tech niques may shorten the duration of labor for some patients. It also should be noted that a low-grade maternal fever might be associated with a normal epidural anesthetic reaction in the absence of infection. In the absence of intra-amniotic infection, neonatal surveillance blood cultures in patients exhibiting this response are negative, indicating no evidence of infection. The advantage of this method of analgesia is that the medication may be titrated over the course of labor as needed. Spinal techniques usually involve a single injection of medication into the cerebrospinal fluid and can provide excellent surgical anesthesia for pro cedures of limited duration, such as cesarean delivery or postpartum tubal ligation, as well as analgesia of limited duration during labor. Spinal labor analgesia using primarily opioids with very low doses of local anesthetics can provide excellent analgesia with rapid onset during labor. Such higher dose techniques typically result in profound sensory and motor blockade, which may impair maternal expulsive efforts. Combined spinal–epidural analgesia offers the advantages of the rapid onset of spinal analgesia along with the ability to use the indwelling epidural catheter to prolong analgesia and titrate medication throughout labor. The technique also may be used and dosed to provide anesthesia for a cesarean delivery and the catheter dosed for postcesarean pain control before being removed. General Intrapartum and Postpartum Care of the Mother 185 anesthesia is rarely used or necessary for vaginal delivery and should be used only for specific indications. At the time of delivery, local anesthetics may be injected into the tissues of the perineum and the vagina to provide anesthesia for episiotomy, and repair of vaginal and perineal lacerations. Cesarean Deliveries For most cesarean deliveries, properly administered regional or general anesthe sia are both effective and have little effect on the newborn. The advantages and disadvantages of both techniques should be discussed with the patient as completely as possible. If obstetric analgesia (other than pudendal or local techniques) is provided by obstetricians, the director of anesthesia services should participate with a representative of the obstetric department in the formulation of procedures designed to ensure the uniform quality of anesthesia services throughout the hospital. An obstetrician may administer the anesthesia if granted privileges for these pro cedures. However, having an anesthesiologist or anesthetist provide this care permits the obstetrician to give undivided attention to the delivery. Strategies thereby can be developed to minimize the need for emergency induction of general anesthesia in women for whom this would be hazardous. For those women with risk factors, consideration should be given to the planned placement in early labor of an intravenous line and an epidural catheter or spinal catheter with confirmation that the catheter is functional. If a woman at unusual risk of complications from anesthesia is identified (eg, prior failed intubation), strong consideration should be given to antepartum referral of the patient to allow for delivery at a hospital that can manage such anesthesia on a 24-hour basis. Aspiration is a significant cause of anesthetic-related maternal morbidity and mortality, and the more acidic the aspirate, the greater the harm done. Therefore, prophylactic administration of an antacid before induction of a major neuraxial or general anesthesia is often appropriate. Particulate antacids may be harmful if aspirated; a clear antacid, such as a solution of 0. Equipment for emergency airway management, such as the laryngeal mask airway, Combitube, and fiberoptic laryngoscope, should be available whenever general anesthesia is administered. Vaginal delivery requires consideration of factors, such as the availability of skilled personnel for the delivery (including obstetric attendants and professionals skilled in neonatal resuscitation and anesthesia administra tion) and the potential need to move a patient from a labor, delivery, and recovery room to an operative suite. The risk assessment performed on the patient’s admission, the course of the patient’s labor, the fetal presentation, any abnormalities encountered during the labor process, and the anesthetic technique in use or anticipated for delivery will all have an effect on the need for other professionals. Under no circumstances should an attempt be made to delay birth by physical restraint or anesthetic means. One factor that markedly influences the chance of uterine rupture is the location of the prior incision on the uterus. Documentation of counseling and the management plan should be included in the medical record. Operative Vaginal Delivery Operative vaginal deliveries are accomplished by applying direct traction on the fetal skull with forceps, or by applying traction to the fetal scalp by means of a vacuum extractor. Operator experience should deter mine which instrument should be used in a particular situation. Operators should attempt to minimize the duration of vacuum application, because cephalohematoma is more likely to occur as the interval increases. Neonatal care providers should be made aware of the mode of delivery to observe for potential complications associated with operative vaginal delivery.

Your neurosurgeon may consider using a long-acting local anesthetic into the muscles and the nerves in the In children, scoliosis can be a presenting symptom in neck to delay the onset of pain. Many times the recurrence may be due to scar tissue formation, or late development of instability or changes that can occur as a result of the opening of the envelope (dura) of the brain. It is important to recognize that even though the patient may get relief of symptoms, the this is essential. There is downward location of the cerebellar tonsils (open arrow) below the rim of the foramen magnum (small black arrow). Often, the spinal cord is actually stuck to the lining of the spinal sac (meninges). If the spinal cord is adherent, or Figure 2 stuck, either toward the back of the sac (dorsal) or the front of the sac (ventral) or to the side (lateral) or in any combination, it is termed a tethered (stuck or adherent) spinal cord. Most often, the surgeon may be associated with various signs and symptoms of will use a dural substitute or a patch-like graft from a neurological dysfunction. In some cases, a weakness (loss of motor function), numbness (loss of synthetic dural substitute may also be used. In rare cases in which untethering fails as the these signs and symptoms can appear individually or in first line of therapy, shunts can still be safely performed any combination and may be unilateral (on one side of the with diversion of the spinal fluid from within the spinal body), bilateral (on both sides of the body), may alternate cord to another cavity or compartment in the body (chest from side to side or be positionally related. Often in cases of diffuse through it, it becomes understandable how even the arachnoiditis (scarring) or multiple failed operations, smallest incision can cause temporary or permanent shunting is necessary. For these reasons, shunts are usually placed in is modified by placing a short piece of the silastic the back of the spinal cord where one is less likely to catheter (shunt) into the cyst and bringing it out just a lose motor strength or pain and temperature sensation. Depending on rather than a shunt, but in reality, it is shunting the which surgeon you talk to or which article you read, spinal fluid from the syrinx cavity into the spinal fluid failure of these operations may result in patients space surrounding the cord rather than into the requiring re-operation or losing function permanently. There are risks that can occur with any It is imperative that every patient feels general anesthetic, that range all the way from death to comfortable with their surgeon and other anesthetic complications. The neurological his/her credentials and experience in complications of spinal cord surgery could include paralysis or weakness, loss of sensation, bowel, bladder this area so that the surgical procedure or sexual dysfunction, as well as infection, hemorrhage, becomes a team effort. Unfortunately, recurrence is not a rare situation even in the experience of the most skilled surgeons, It is imperative that every patient feels comfortable with and even when patients follow the medical advice for their surgeon and his/her credentials and experience in postoperative activity. If tethering or cyst formation this area so that the surgical procedure becomes a team recurs, treatment may require revision or repeat effort. The majority of patients can expect to stop the others should have full knowledge and understanding progression of their symptoms with surgery. When often there is a reversal of some, and less commonly of surgery is performed with the surgeon and patient all of the preoperative signs and symptoms. As working together as a team in every sense, it can result mentioned previously, some patients may be in the best possible outcome for everyone involved. They, as well, are associated with significant overlap regarding both symptoms and surgery. In order to understand what an individual undergoing surgery for either or both of these entities can expect, it behooves us to divide the surgical process into: (1) the events that occur before surgery, (2) the surgery itself, and (3) the events that occur following surgery. Then, the patient and the patient’s family and friends participate in an ongoing dialogue with the surgeon regarding the pros and cons of surgery and the strategies for surgical intervention. First and foremost, it should not be assumed that the presence of either a Chiari malformation or the presence of syrinx constitutes, in and of itself, an indication for surgery. The progression of a syrinx on imaging studies, significant symptoms, or progression of symptoms, in the presence of the anatomical findings consistent with a Chiari malformation and/or syrinx constitute the indication constellation for surgery. Patients should understand this concept and should “interrogate” their surgeon regarding this decision-making process. Realistic expectations regarding outcome, weighed against risk, can then be understood and considered preoperatively. The Surgical Procedure From the patient’s perspective, surgery is painful and is associated with some risks. Assuming that no neurological complications of surgery ensue, the other major risks of surgery include leakage of spinal fluid, pseudomeningocele formation (spinal fluid that has leaked from the spinal sac but is contained under the skin), bleeding and infection. Almost all (but not all) surgical procedures for Chiari malformation and syringomyelia are performed in the prone (face down) position. Most surgeons use skull fixation during Chiari surgery in order to immobilize the operative site. This may cause the patient to have some pain at sites (usually three) where the pins of the skull fixation device have penetrated the skin and attach to the skull during surgery. The patient can expect to be unaware of this device, since it is applied after the patient is asleep and is removed before the patient emerges or awakens from general anesthesia. The incision for the Chiari malformation is usually located in the lower part of the back of the skull and the upper part of the neck in the midline. The incision for a syrinx can be located at any point in the posterior neck or upper back, depending on the location of the syrinx cavity. Although both operations may be painful, Chiari malformation surgery is usually associated with a greater amount of pain due to muscle retraction and the dissection required to perform the surgery. After Surgery and the Postoperative Period the postoperative period can be divided into several phases: (1) hospital phase, (2) the first months after surgery, and (3) the long-term period. Neurological Neurological or symptomatic deterioration can be multi complications obviously may ensue, as well as spinal fluid factorial. Most other complications (therefore no surgical treatment indicated) or other are relatively infrequent and are usually unique to the surgical pathology identified, such as basilar impression, specific situation at hand.
