order 4 mg doxazosin amex

ECT obviates high doses of various medications generic 4mg doxazosin with visa, thus minimizing the medication reaching the breast-fed baby purchase doxazosin 1mg. The frequency of ECT is determined by clinical response cheap 1 mg doxazosin amex. Often, on completion of a course of ECT, when remission has been achieved, one ECT continues to be given at weekly intervals. This is usually gradually extended out to one treatment each 4 or 6 weeks (Gagne et al, 2000). The National Institute for Clinical Evidence (2003) in the UK, does not recommend maintenance ECT. The American Psychiatric Association does, and there is a continuous, but modest, stream of publications (Nordenskjold et al, 2013). The procedure Preparatory work includes making an accurate diagnosis (disappointment and personality disorder, for example, do not respond to ECT), communication with the patient and family, anaesthetic assessment, and deciding on the most appropriate electrode placements. Generally, the stimulus is applied using one of two electrode arrangements. In bilateral stimulation, one electrode is placed on either side of the forehead and the electricity passes through both sides of the brain. In unilateral stimulation, one electrode is attached to one side of the forehead and the second is placed further back on the scalp on the same side of the head. With unilateral stimulation the electricity remains predominantly on one side of the head. Here, electrodes are placed on the forehead, above the eyes. Results have been very encouraging (Phutane et al, 2013). Theoretically, this could give the greater efficacy of bilateral ECT, and with a smaller region of the brain exposed to electricity, minimal cognitive side-effects. Two sets of electrodes are attached to the patient to monitor the activity of the brain before, during and after ECT administration. One set is placed on the scalp (EEG) and the other on a limb. The observations assist in decision making regarding the adequacy of the physiological response. An anaesthetist, psychiatrist and at least two nurses are present. The anaesthetist inserts a cannula, an anaesthetic nurse attaches ECG electrodes, and the psychiatrist and psychiatric nurse attach ECT, EEG and peripheral muscle electrodes. When muscle relaxation has occurred, the ECT stimulus is applied. Using one popular device (Thymatron), the stimulus is delivered at a maximum frequency of 70 pulses per second. The longest the stimulus can continue, using this device, is 8 seconds. Usually there is bending of the elbows and pointing of the toes. When the convulsion has stopped (generally less than 30 seconds) the patient is rolled onto the side and transported to the recovery room. The whole procedure from arrival to departure from the procedure room takes in the order of 10 minutes. Electrode placement As mentioned, there are two main electrode placements, bilateral and unilateral. Memory is not located in any one particular region of the brain - current wisdom is that memory depends on many regions of the brain being anatomically and functionally linked together. It is known that severe memory problems occur when structures on both sides of the brain are damaged, for example, when both left and right temporal lobes are destroyed. There is evidence to indicate that bilateral ECT has a stronger antidepressant effect than unilateral ECT (UK ECT Review Group, 2003). However, bilateral ECT is also believed to be associated with greater temporary memory disturbance than unilateral ECT. Evidence shows that delivering a substantially larger amount of electrical energy unilaterally than is required to simply trigger a convulsion (“seizure threshold”) can produce similar antidepressant effects as bilateral ECT, but with less memory disturbance (Sackheim et al, 1993). This “high dose unilateral ECT” is now the most often chosen form. However, when a maximum antidepressant effect is required, bilateral ECT may be necessary. Dose determination Current thinking is that optimum antidepressant effect is achieved with electrical doses well above the seizure threshold (Sackheim et al, 1993). One is by first determining the “seizure threshold”. In this method a number of stimuli are applied, starting at a low level, and increasing the electrical energy of subsequent stimuli until a seizure is triggered. Treatment is then provided with a stimulus 2-3 times higher Pridmore S. This is called the “stimulus titration method”, and is favoured by many experts (Tiller and Ingram, 2006). Alternatives include delivering a dose determined by age (“age-based dosing algorithm”; Abrams 2002a), or a fixed high dose (Abrams 2002b). The jury is still out on whether the “stimulus titration method” or the “age-based algorithm” is the better method of dose determination. The APA Taskforce on the Practice of ECT (2001) approves both.

Also, Na may enter the cell via the NMDA recep- tor-gated channel and depolarize the neuron. Thus, excito- toxicity may be ameliorated at a number of sites in vivo. MECHANISMS OF PROGRAMMED CELL Many drugs that can inhibit excitotoxicity at each of DEATH these steps have been developed. GABA agonists such as clomethazole have been shown to be neuroprotective in vivo Many of the key molecular events in programmed cell death and are currently undergoing clinical trials (47,48).

Drugs that prevent prolonged opening of P- and Q-type calcium chan- nel antagonists are also neuroprotective in animal models of stroke (52). In contrast to their very limited effects in primary neuronal tissue culture models, non-NMDA antag- onists are very effective in both global and focal ischemia models in rodents. Indeed, such agents have a longer time window of efficacy than do NMDA antagonists when ad- ministered after the onset of ischemia (53,54). Likewise, voltage-dependent calcium channel antagonists are not ef- fective in vitro; however, the voltage-dependent calcium channel antagonist nimodipine is effective in reducing in- farction volume in temporary focal ischemia in rats (55). Blockade of excitotoxicity via all these pharmacologic strategies has proved effective in temporary focal ischemia models in rodents, the model that most closely resembles human stroke. Unfortunately, results with these agents in human trials have to date been very disappointing, for sev- eral possible reasons. First, drugs that affect neurotransmis- sion in the brain have many undesirable side effects, which in turn have led to reductions to doses that may have been ineffective. Side effects include effects on respiration and cardiac rhythm. In addition, agents that directly antagonize the NMDA receptor may injure a circumspect population of neurons in the cingulate and retrosplenial cortex in ro- dents (56), and may induce hallucinations and psychosis in humans (57). Another obvious reason for the lack of efficacy in these drugs in clinical trials is the time interval between the onset of ischemia and the administration of drug. When given before the onset of ischemia, these treatments can spare 50% or more of ischemic rat brain tissue from eventual FIGURE 92. A schematic diagram illustrating the molecular infarction. When given after the onset of ischemia, they are mechanisms that control programmed cell death. Caspase 9 then cleaves and activates other cas- (69,70).
