We examined the efficacy and safety of electroshock therapy (EST) under general anesthesia in 26 depressed patients (9 males, 17 females, age range 55-79). The scores of the Hamilton Psychiatric Rating Scale for depression were significantly decreased after EST and clinical symptoms such as depressive mood. psychomotor retardation, anxiety, agitation, suicidal tendencies, hypochondria and sleeplessness improved in all of the patients. Complications included amnesia (16/26), delirium (3/26) and transient arrhythmia (1/26) after EST, but neither lethal nor lasting complications were observed. In summary, EST was an effective and convenient method of treatment for senile depression.

Several situations arise in the PICU patient that require the administration of drugs for sedation and analgesia. A "cookbook" approach is impossible because of the diversity of patient and clinical scenarios. When amnesia is required, these authors prefer a continuous infusion of a benzodiazepine such as midazolam or lorazepam. Although the majority of clinical experience has been with midazolam, lorazepam either by bolus dose or continuous infusion offers a cost-effective alternative. When analgesia is required, the addition of a continuous infusion of narcotic or the use of a PCA device in the older patient should prove effective. Although fentanyl is frequently chosen, morphine is an effective and cost-effective alternative for patients with stable cardiovascular function. The synthetic narcotics are recommended for neonates, especially following cardiac surgical procedures and those at risk for pulmonary vasospasm. Narcotics may also be used for the treatment of agitation in those situations that do not necessarily require analgesia. Our clinical experience suggests that narcotics may be more effective for sedation than benzodiazepines in children less than 1 year of age. When the above agents fail to be effective or are associated with cardiovascular depression, alternatives may include ketamine or pentobarbital. Ketamine may be useful for the unstable patient or those with a bronchospastic component to their disease process. We have found pentobarbital to be effective when the combination of benzodiazepines and narcotics fails to provide the desired level of sedation. Aside from these techniques, regional anesthesia may offer a more effective means of controlling pain in the PICU patient. These techniques may be effective when parenteral narcotics are inadequate or lead to undesired effects. Although most commonly used for postoperative analgesia, their use in patients with pain from other causes (e.g., multiple trauma) may be indicated, especially when parenteral narcotics may interfere with respiratory function or the ongoing assessment of the patient's mental status.

As colonoscopy is often painful, a premedication appears to be indispensable. Commonly, benzodiazepines, i.e. midazolam, alone or in combination with analgesic drugs are used. Besides all advantages, midazolam especially is known to have the risk of oversedation and respiratory depression. Therefore it should be used at minimal dose. In a double-blind, randomized study, three premedication-schedules of midazolam (mid) plus ketamine (ket) were compared in 33 patients, aged between 8 and 60 years, with regard to safety and acceptance by patients and endoscopist. I: ket 1 mg/kg+mid 0.1 mg/kg, max. 5 mg II: ket 1 mg/kg+mid 0.05 mg/kg, max. 2.5 mg III: ket 0.75 mg/kg+mid 0.1 mg/kg, max. 5 mg Oxygen-saturation, heart rate and blood pressure were recorded as well as the evaluations of sedation, cooperation and complaint of pain. To assess the recovery-time of the patients, the reaction time and the attention were evaluated by "Wiener's determination apparatus" and "test d2", respectively, before and at 1, 2, 3 and 4 hours after premedication. Medication I resulted in heavy sedation, good cooperation and amnesia but had the strongest tendency towards hypoxemia. Under schedule III, reduced cooperation and acceptance were seen due to a strong experience of pain. The best conditions during the examination with regard to cooperation, experience of pain and acceptance were found after premedication II without relevant depression of vital parameters. It can be concluded that midazolam can be used at minimal recommended doses as premedication for colonoscopy if combined with ketamine in a sufficient analgesic dosage.

We evaluated the effectiveness of rectally administered midazolam for preoperative sedation in 26 cases of childhood moyamoya disease. The patients, aged 5.0 +/- 1.8 yr (mean +/- SD), received 1 mg.kg-1 of midazolam 30 min prior to induction of anesthesia. The patient's level of sedation, tolerance of anesthesia face mask, and amnesia were evaluated. In 22 of 26 patients induction via face mask was performed smoothly, and excellent anterograde amnesia was observed. Remarkable complications, including hemodynamic and/or respiratory depression, were not noted. The level of sedation was significantly related to the patient's age. Although further investigation to evaluate proper dose are needed, 1 mg.kg-1 of rectally administered midazolam is useful for childhood moyamoya disease, in which crying can worsen the neurological symptoms.

The use of sedation and monitoring in gastrointestinal endoscopy is still open for debate. In The Netherlands, generally, no systemic sedation is used for relatively simple procedures like diagnostic upper GI endoscopy and sigmoidoscopy. In most centres, for more time-consuming and burdensome endoscopies like colonoscopy, ERCP, sclerotherapy and therapeutic procedures, some form of sedation is applied. In a survey among a number of University Hospitals in The Netherlands it was shown that the sedatives mostly used are midazolam and diazepam. In more complex endoscopies these sedatives are often combined with narcotics like pethidine, morphine, fentanyl or thalamonal. Equipment to monitor the effect of these compounds on respiratory or cardiovascular function is not routinely available. However, there is a tendency towards the use of monitoring equipment and more specific to the use of pulse oximetry. Endpoints of conscious sedation are anxiolysis, amnesia and cooperation; it should not lead to ptosis, dysarthria and drowsiness. Features of drugs for conscious sedation should include these aforementioned points as well as a defined dose-effect relationship and a broad therapeutic window. Furthermore, they should be water soluble and give rapid recovery. Signs of oversedation are hypotension, bradycardia and respiratory depression. Competitive antagonists to the receptor, like flumazenil, can reverse overdosage of benzodiazepine sedatives. The sedative of choice at this moment is midazolam. When a benzodiazepine is combined with a narcotic, the narcotic should be given first and the dosage of the sedative adjusted.(ABSTRACT TRUNCATED AT 250 WORDS)

A 60-year-old lady with previous hypertension was studied with PET in the acute (early recovery) phase of an otherwise typical episode of transient global amnesia (TGA). Follow-up over > 1 year was uneventful, and delayed CT scans and MRI showed no brain damage. No medical cause was disclosed despite extensive work-up. The PET study revealed a matched reduction in cerebral blood flow and oxygen consumption over the entire lateral frontal cortex on the right side, with an associated, less significant reduction in ipsilateral thalamic and lentiform nucleus metabolism, but sparing the hippocampal area. These changes, which had resolved at a repeat PET study 3 months later, suggest right prefrontal metabolic depression, possibly secondary to thalamic dysfunction, as the underlying mechanism for TGA in this case, consistent with the emerging involvement of the prefrontal cortex in strategies or control of memory traces retrieval. Thus, in analogy with permanent amnesia, TGA may be a core syndrome with several possible foci of dysfunction along the neuronal networks that subserve explicit memory. In the future, combined PET neuropsychological assessment in the acute stage of TGA may prove useful in defining distinct neuropsychological-topographical subtypes of this intriguing clinical entity.

Vascular dementia (VAD) is common, and small vessel disease is one of the most frequent etiologies of the disorder. Lacunar state and Binswanger's disease are the two types of VAD associated with small vessel disease. Lacunar state and Binswanger's disease produce a dementia syndrome with characteristics of subcortical dementia including slowing of information processing, impaired memory, and poor sustained attention. Executive dysfunction includes poor word list generation and verbal fluency (design generation), impaired motor programming with perseveration and impersistence, and difficulty with set shifting. Memory loss in subcortical VAD is characterized by poor retrieval and intact recognition. Apathy is ubiquitous in VAD and depression and psychosis are common. Parkinsonism with prominent gait disturbances in conjunction with pyramidal tract signs, dysarthria, pseudobulbar affect, and incontinence are frequent motor manifestations of VAD with small vessel disease. The lesions of subcortical VAD affect the structures--caudate nucleus, globus pallidus, thalamus-and connecting fibers of frontal--subcortical circuits and produce a clinical syndrome similar to that seen in other subcortical diseases.

We compared effects of midazolam as intramuscular premedicant on hypnosis, sedation and antegrade amnesia when administered 15 (32 cases) and 30 (35 cases) min before induction of anesthesia. Hypnosis was obtained in 97 and 91%, and sedation in 97 and 100% of patients administered midazolam 15 and 30 min before induction, respectively. Antegrade amnesia was observed in 97 and 72% of patients administered midazolam 15 and 30 min before, respectively (statistically significant). If midazolam is administered 15 min before, the respiratory depression, one of its unacceptable side effects, may hardly occur because patient arrives operating room before its onset. We conclude that the appropriate time for administration of midazolam as intramuscular premedicant is 15 min, rather than 30 min, before the induction of anesthesia.

This retrospective study analyzed the cases of difficult intubations carried out with a fiberoptic bronchoscope between March 1984 and May 1989. During this period, 222 such procedures were attempted in 131 male and 68 female patients. All cases were diagnosed at the preoperative visit. A fiberoptic bronchoscope was used as a guide under topical nasal and laryngeal anaesthesia, together with appropriate benzodiazanalgesia, in order to maintain spontaneous breathing. The nasotracheal route was used in 218 cases. Successful intubation was achieved in 219 cases (98.6%), 209 of them (95.4%) within fifteen minutes. Of the three failures, only one was unpredictable (inability to withdraw the fiberoptic bronchoscope from the endotracheal tube). In the two others, the technique was subsequently found to have been wrongly indicated: major nasopharyngeal secretions occluded the fiberoptic device in the first one, and an anatomically compromised airway led to apnoea under sedation in the other. A narrow nasotracheal passage, spreading oedema, bloody secretions or coughing gave rise to technical difficulties in 39 cases (17.5%). There was one case of regurgitation without any drawback. Benzodiazanalgesia was responsible for two cases of respiratory depression. This technique was otherwise very satisfactory, patients being cooperative and frequently having amnesia of intubation. The indications for the use of a fiberoptic bronchoscope were: insufficient oral opening, orofacial obstacles to laryngoscopy, and cases where laryngoscopy had to be avoided. The main drawbacks of this technique were the cost and fragility of fiberoptic device as well as operator efficiency. The anaesthesiologists involved in the present series performed ten easy intubations each with the fiberoptic bronchoscope, and routinely used the teaching eye-piece.(ABSTRACT TRUNCATED AT 250 WORDS)

The amino acids L-glutamate and L-aspartate have been shown to be excitatory neurotransmitters in mammalian central nervous systems. Antagonists acting selectively at excitatory amino acid receptors have shown antiepileptic properties in several animal models. We report the results of the first therapeutic trial of the competitive NMDA antagonist, D-CPP-ene (SDZ EAA-494), in eight patients with intractable complex partial seizures. All patients withdrew prematurely because of side-effects, including poor concentration (8), sedation (7), ataxia (6), depression (3), dysarthria (2), amnesia (2) and unilateral choreo-athetosis in a patient with contralateral Sturge-Weber syndrome. Seizures were unchanged in four patients and worse in three. A further patient with apparent improvement in seizures in the first week developed complex partial status epilepticus on withdrawal of DCPP-ene. EEG on treatment (5) or in the immediate post-treatment period (2) showed slowing of background activity and, in five cases, an increase in epileptiform activity. Serum concentrations of DCPP-ene were found to be unpredictable and higher than expected from pharmacokinetic data on normal subjects. There was no clear relationship between serum concentrations and the severity of side-effects. Preliminary experience with DCPP-ene in patients with refractory partial seizures is not promising. Evaluation of related compounds is warranted.
