Introduction

Psychiatric illness during pregnancy often presents a clinical dilemma. Pharmacologic interventions that are usually effective for these disorders have teratogenic potential and are therefore contraindicated during pregnancy. However, for depression, mania, catatonia, Buy keppra in canada, and schizophrenia, an alternative treatment exists: electroconvulsive therapy (ECT), the induction of a series of generalized seizures.

Psychiatric Treatment during Pregnancy

Pharmacologic therapies pose risks to the fetus in pregnant patients. Antipsychotics, particularly phenothiazines, have been noted to cause congenital anomalies in babies born to women treated with these medications during pregnancy (Rumeau-Rouquette 1977), buy keppra without prescription. Congenital defects have also been associated with the use of lithium, especially when administered during the first trimester (Weinstein 1977). However, in a recent study by Jacobson et al, keppra sale. (1992), no association between lithium and congenital anomalies was found. Tricyclic antidepressants have been associated with limb reduction deformities (McBride 1972) and, moreover, take four to six weeks to affect depression. Buy keppra without prescription, During this time, risk to the fetus and woman may be substantial, depending on the mental and psychologic condition of the mother, her ability to care for herself, and possible suicidality. In a crisis situation in which the risks of untreated symptoms are extreme, Online pharmacy keppra, the patient is known to be refractory to medications, or the medication represents a substantial risk to the fetus, ECT represents a valuable alternative in the pregnant patient. When administered by trained staff, and when precautions germane to pregnancy are taken into account, ECT is a relatively safe and effective treatment during pregnancy.

ECT: The History

Electroconvulsive therapy was first introduced as an effective treatment option for psychiatric illness in 1938 by Cerletti and Bini (Endler 1988). Several years earlier in 1934, buy keppra online cheap, Ladislas Meduna introduced the induction of generalized seizures with the pharmacological agents camphor and then pentylenetetrazol as effective treatment in a number of psychiatric illnesses. Prior to this time, no effective biological treatment for psychiatric illness was in use, buy keppra without prescription. The work of Meduna therefore, opened a new era of psychiatric practice and was quickly accepted throughout the world (M. Fink, personal communication). With the discovery that more predictable and effective seizures could be induced by ECT, Keppra online without prescription, the pharmacological method fell into disuse. ECT persisted as a mainstay of therapy until the 1950s and 1960s, when effective antipsychotic, antidepressant, and antimanic drugs were discovered (Weiner 1994). Buy keppra without prescription, ECT was largely replaced by medications from this point until the early 1980s, when its usage level stabilized. However, a renewed interest in ECT in the medical community, prompted by failures of pharmacotherapy, buying keppra online, has led to an increase in its judicious use in treatment-refractory patients with several psychiatric illnesses, including depression, mania, catatonia, and schizophrenia and also in circumstances in which psychopharmacological treatment is contraindicated, such as during pregnancy (Fink 1987 and personal communication). Keppra side effects, ECT: The Procedure

Standard procedure. During the procedure, the patient is administered a short-acting barbiturate, typically methohexital or thiopental, which puts the patient to sleep, and succinylcholine, which induces paralysis. Paralysis suppresses the peripheral manifestations of the seizure, keppra without a prescription, protecting the patient from fractures caused by muscular contractions and other injuries induced by the seizure. The patient is ventilated with 100% oxygen through a bag and hyperventilated before the electrical stimulus is administered, buy keppra without prescription. An EEG should be monitored. The stimulus is applied either unilaterally or bilaterally, inducing a seizure that should last at least 35 seconds by EEG. The patient is asleep for 2 to 3 minutes and awakens gradually. Vital signs are monitored throughout (American Psychiatric Association 1990). Buy keppra without prescription, Systemic changes that may occur during ECT include a brief episode of hypotension and bradycardia, followed by sinus tachycardia and sympathetic hyperactivity with an increase in blood pressure. Cheap keppra without prescription, These changes are transient and typically resolve over the course of minutes. The patient may experience some confusion, headache, nausea, myalgia, and anterograde amnesia following the treatment. These side effects generally clear over the course of several weeks following completion of the treatment series but can take up to six months to resolve. In addition, find keppra no prescription required, the incidence of side effects has been decreasing over the years as ECT technique has improved (American Psychiatric Association 1990). Finally, the mortality rate associated with ECT is approximately only 4 per 100,000 treatments and is generally cardiac in origin (Fink 1979), buy keppra without prescription.

During pregnancy. ECT has been found safe during all trimesters of pregnancy by the American Psychiatric Association. However, all ECT on pregnant women should occur in a hospital with facilities to manage a fetal emergency (Miller 1994). During pregnancy, Order keppra no rx, several recommendations are added to the standard procedure to decrease potential risks. Buy keppra without prescription, An obstetric consultation should be considered in high-risk patients. Vaginal exam is not obligatory, though, since it is relatively contraindicated during pregnancy. Furthermore, nothing about the vaginal exam would affect ECT. In the past, external fetal cardiac monitoring during the procedure was recommended, purchase keppra overnight delivery. However, no alteration in fetal heart rate has been observed. Therefore, fetal monitoring as a routine part of the procedure is not warranted given its expense and lack of utility (M, buy keppra without prescription. Fink, personal communication). In high-risk cases, the presence of an obstetrician during the procedure is recommended. Keppra prescription, If the patient is in the second half of pregnancy, intubation is the standard of anesthetic care to reduce the risk of pulmonary aspiration and resultant aspiration pneumonitis. During pregnancy, gastric emptying is prolonged, increasing the risk of aspiration of regurgitated gastric contents during ECT. Buy keppra without prescription, Pneumonitis may result following aspiration of particulate matter or acidic fluid from the stomach. Standard procedure requires the patient to take nothing by mouth after midnight the night preceding ECT. However, in the pregnant patient this is often insufficient to prevent regurgitation, keppra online. In the second half of pregnancy, intubation is performed routinely to isolate the airway and reduce the risk of aspiration. In addition, administering a nonparticulate antacid, such as sodium citrate, to raise gastric pH, Keppra non prescription, may be considered as optional adjuvant therapy, but its usefulness is debated (Miller 1994, M. Fink, personal communication), buy keppra without prescription.

Later in pregnancy, risk of aortocaval compression becomes a concern. As the uterus increases in size and weight, it may compress the inferior vena cava and lower aorta when the patient is in the supine position, as she is during ECT treatment, keppra online pharmacy. With compression of these major vessels, increased heart rate and peripheral resistance compensate but perhaps insufficiently to maintain placental perfusion. This can be prevented, however, by elevating the patient's right hip during the ECT treatment, which displaces the uterus to the left, Order keppra no prescription required, relieving pressure on the major vessels. Buy keppra without prescription, Assuring hydration with adequate fluid intake or intravenous hydration with Ringer's lactate or normal saline before ECT treatment will also reduce this risk of reduced placental perfusion (Miller 1994).

ECT During Pregnancy:

Risks and Complications

Reported complications. In a retrospective study of ECT use during pregnancy by Miller (1994), 28 of 300 cases (9.3%) reviewed from the literature from 1942 to 1991 reported complications associated with ECT. The most common complication found by this study is fetal cardiac arrhythmia. Noted in five cases (1.6%), disturbances in fetal cardiac rhythm included irregular fetal heart rate up to 15 minutes postictally, fetal bradycardia, buy keppra cheap, and reduced variability in fetal heart rate. The latter is hypothesized to have been in response to barbiturate anesthetic, buy keppra without prescription. The disturbances were transient and self-limited, and a healthy baby was born in each case.

Five cases (1.6%) also reported known or suspected vaginal bleeding related to ECT. Mild abruptio placentae was the cause of bleeding in one case and recurred after each of a weekly series of seven ECT treatments. No source of bleeding was identified in the remaining cases. Buy keppra without prescription, However, in one of these cases, the patient had experienced similar bleeding in a previous pregnancy during which she received no ECT. Find discount keppra, In all these cases, the baby was again born healthy.

Two cases (0.6%) reported uterine contraction following shortly after ECT treatment. Neither resulted in any noticeable adverse consequences. Three cases (1.0%) reported severe abdominal pain directly following ECT treatment. The etiology of the pain, which resolved following the treatment, was unknown, buy keppra without prescription. In all cases, healthy babies were born.

Four cases (1.3%) reported premature labor after the patient received ECT during pregnancy; however, buy discount keppra, labor did not immediately follow ECT treatment, and it appears ECT was not related to the premature labors. Similarly, five cases (1.6%) reported miscarriage in pregnant patients who received ECT during their pregnancy. One case appeared to be due to an accident. Buy keppra without prescription, However, as Miller (1994) points out, even including this latter case, a miscarriage rate of 1.6 percent is still not significantly higher than that of the general population, suggesting that ECT does not increase the risk of miscarriage. Three cases (1.0%) of stillbirth or neonatal death in patients undergoing ECT during pregnancy were reported, Keppra online without a prescription, but these appear to be due to medical complications unrelated to the ECT treatment.

Medication risks.

Succinylcholine, the muscle relaxant most commonly used to induce paralysis for ECT, has undergone limited study in pregnant women. It does not cross the placenta in detectable amounts (Moya and Kvisselgaard 1961). Succinylcholine is inactivated by the enzyme pseudocholinesterase, buy keppra without prescription. Approximately four percent of the population is deficient in this enzyme and could, consequently, keppra medication, have a prolonged response to succinylcholine. In addition, during pregnancy, pseudocholinesterase levels are low, so this prolonged response is not infrequent and could occur in any patient (Ferrill 1992). In the Collaborative Perinatal Project (Heinonen et al. Certified keppra, 1977), 26 births to women exposed to succinylcholine during the first trimester of pregnancy were assessed after birth. Buy keppra without prescription, No abnormalities were noted. However, several case reports noted complications in the use of succinylcholine during the third trimester of pregnancy. The most notable complication studied in women undergoing caesarian section was development of prolonged apnea that required continuous ventilation and lasted several hours to days. In nearly all the infants, respiratory depression and low Apgar scores were seen after birth (Cherala 1989).

Pharyngeal secretions and excessive vagal bradycardia can also occur during ECT treatments, keppra buy drug. To prevent these effects during the procedure, anticholinergic agents are often administered prior to ECT, buy keppra without prescription. The two anticholinergics of choice are atropine and glycopyrrolate. In the Collaborative Perinatal Project (Heinonen et al. 1977), 401 women received atropine, and four women received glycopyrrolate during their first trimester of pregnancy. In the women who received atropine, Canada keppra, 17 infants (4%) with malformations were born, while in the glycopyrrolate group, no malformations were seen. Buy keppra without prescription, The incidence of malformations in the atropine group was not greater than would be expected in the general population. Likewise, studies of these two anticholinergics used in the third trimester of pregnancy or during labor did not reveal any adverse effects (Ferrill 1992).

To induce sedation and amnesia prior to the treatment, a short-acting barbiturate is typically used. The agents of choice, order keppra on internet, methohexital, thiopental, and thiamylal, have no known adverse effects associated with pregnancy (Ferrill 1992). The only known exception is that administration of a barbiturate to a pregnant woman with acute porphyria may trigger an attack. Elliot et al, buy keppra without prescription. (1982) conclude that the recommended dose of methohexital in nonpregnant adults appears to be safe for use during the third trimester of pregnancy. Buy keppra from india, Teratogenicity. In the retrospective study by Miller (1994), five cases (1.6%) of congenital abnormalities were reported in children of patients who underwent ECT during pregnancy. The cases with noted abnormalities include an infant with hypertelorism and optic atrophy, an anencephalic infant, another infant with clubfoot, and two infants demonstrating pulmonary cysts. Buy keppra without prescription, In the case of the infant with hypertelorism and optic atrophy, the mother received only two ECT treatments during the course of her pregnancy; however, she had received 35 insulin coma therapy treatments, which are suspected of teratogenic potential. As Miller notes, discount keppra no rx, no information on other potential teratogenic exposures was included in these studies. Based on the number and pattern of congenital anomalies in these cases, she concludes that ECT does not appear to have an associated teratogenic risk.

Long-term effects in children. Literature examining the long-term effects of ECT treatment during pregnancy is limited. Smith (1956) examined 15 children between the ages of 11 months and five years whose mothers had undergone ECT during pregnancy, buy keppra without prescription. None of the children demonstrated intellectual or physical abnormalities. Keppra from canada, Sixteen children, aged 16 months to six years, whose mothers had received ECT during the first or second trimester of pregnancy, were examined by Forssman (1955). None of the children was found to have a defined physical or mental defect. Impastato et al. Buy keppra without prescription, (1964) describes follow-up on eight children whose mothers had received ECT during pregnancy. The children ranged in age from two weeks to 19 years at the time of examination. No physical deficits were noted; however, keppra tablets, mental deficiencies were noted in two and neurotic traits in four. Whether ECT contributed to the mental deficits is questionable. The mothers of the two mentally deficient children had received ECT after the first trimester, and one received insulin coma treatment during the first trimester, which could have contributed to the mental deficit.

Summary

ECT offers a valuable alternative for treating the pregnant patient suffering from depression, mania, catatonia, or schizophrenia, buy keppra without prescription. Pharmacological therapy for these psychiatric illnesses carries inherent risks of side effects and adverse consequences to the unborn child. Cost keppra, Medications often require a long time to take effect, or the patient may be refractory to them. Additionally, these psychiatric conditions themselves are a risk to the mother and fetus. An effective, expeditious, and relatively safe alternative for pregnant patients requiring psychiatric treatment is ECT. Buy keppra without prescription, The risk of the procedure can be minimized by modifying the technique. Medications used during the procedure are reportedly safe to use during pregnancy, low cost keppra. In addition, complications reported in pregnant patients who received ECT during pregnancy have not been conclusively associated with the treatment. Research conducted to date suggests that ECT is a useful resource in psychiatric treatment of the pregnant patient.
