Benzodiazepines have so many uses in cancer patients that the physician may target more than one advantage as he considers choice of drug and dose. Nausea, pain, and anxiety may be treated simultaneously. Since these patients are often taking a number of medications, the simplest regimen has the most benefit. These drugs treat reactive anxiety, insomnia, claustrophobia, and panic disorder. As they treat anticipatory anxiety and phobia, they mitigate anticipatory nausea and a component of post-treatment nausea. With chemotherapy itself, they cause sedation, suppress recall of treatment, limit vomiting, and are seen as desirable by patients. They suppress the restlessness associated with metoclopramide and other dopamine-antagonist antiemetics. The analgesic effects are best seen in conditions of high anxiety, muscle spasm, and deafferentation syndromes. The advantages of sedative and antipsychotic effects may be exploited to suppress the psychiatric complications of high-dose corticosteroids.

Aside from being hard for physicians and staff to cope with, ICU agitation syndromes result in deterioration of hemodynamics and must be handled effectively. The interaction between pain and delirium is examined, as well as hemodynamic and metabolic syndromes that cause agitation in the ICU setting. The various medications useful in the treatment of pain and delirium are reviewed and new regimens discussed. Comprehensive treatment plans are reviewed for the profoundly agitated patient.

This randomized, double-blind study evaluated the antiemetic efficacy and the side-effects of promethazine pretreatment (0.5 mg.kg-1 IV + 0.5 mg.kg-1 IM) versus droperidol + placebo pretreatment (droperidol, 0.075 mg.kg-1 IV + physiological saline, 0.02 ml.kg-1 IM). One hundred unpremedicated ASA physical status I children ranging from two to ten years, and undergoing outpatient strabismus surgery were studied. All children received inhalational anaesthesia with halothane, nitrous oxide and oxygen. Neither opioids nor muscle relaxants were used. The incidence of vomiting and/or retching and the incidence of side-effects were determined in the post-anaesthesia recovery room (PARR), in the short-stay surgical unit (SSSU), and after discharge from the hospital (including the journey and the stay at home during the first postoperative day). Promethazine and droperidol were equally effective in reducing the incidence of vomiting before discharge to two and eight per cent respectively. On the contrary, the incidence of vomiting after discharge and overall were significantly less with promethazine (ten and ten per cent) than with droperidol pretreatment (54 and 56 per cent) (P less than 0.0001). Promethazine permitted the time to discharge from the hospital to be reduced to an average of three hours, without increasing the incidence of vomiting postdischarge. Promethazine pretreatment is much less expensive than droperidol pretreatment. The incidence of restlessness was significantly less with droperidol (eight per cent) than with promethazine (36 per cent) (P less than 0.001). Promethazine pretreatment demands the use of an analgesic like acetaminophen in order to reduce the incidence of postoperative pain and restlessness.(ABSTRACT TRUNCATED AT 250 WORDS)

Propofol or methohexitone was given to the same twenty patients on two separate occasions during total intravenous anaesthesia for microlaryngeal surgery. With propofol the quality of induction was superior. Fewer patients required supplementation. Heart rate and blood pressure were well controlled at levels of 110-120% baseline. There were fewer side-effects during maintenance and recovery. Patients were able to return home earlier. However, apnoea and pain on injection occurred frequently, the latter when injection was made into the dorsum of the hand. With methohexitone, apnoea, abnormal movement, nausea, vomiting, headache, restlessness and confusion were common. Cardiovascular variables were poorly maintained at levels of 170-180% baseline. The results suggest that propofol is suitable as the sole anaesthetic agent in patients undergoing microlaryngeal surgery.

The possibility of prolonging the effect of intrathecally injected meperidine by the use of a lipid solution was examined in this study. An aqueous solution of 5% meperidine HCl, 250 micrograms/kg, and an equimolar solution of meperidine dissolved in iophendylate (Pantopaque) were injected subarachnoidally in two groups of rabbits (n = 9 in each) with chronically implanted catheters in the subarachnoid space at the level of L7-8. The effect of each injection was assessed by evaluation of the pain threshold in the animal's hind limbs and of the degree of motor blockade produced. The duration of analgesia and of motor blockade were significantly longer when the lipid solution was used. Six of nine animals that received the aqueous solution of 5% meperidine HCl exhibited temporary signs of agitation (i.e., biting of hind limbs). None of the animals given the lipid solution of the drug did. The findings are attributed to the slow release of meperidine from the lipid phase that serves as a drug depot in the cerebrospinal fluid. The approach presented is suggested as a basis for the development of lipid solutions that might prolong the duration of spinal analgesia produced by a single intrathecal injection.

In the last few years the non cardiac angina-like chest pain has encompassed more and more agitation not only in many patients but also in cardiologists, gastroenterologists and psychologists, as it involves socio-economic, pathophysiologic and therapeutic problems. The socio-economic aspect is well explained by the fact that in the USA at least 200,000 patients a year suffering from non cardiac angina-like chest pain, even when coronary arteriography has demonstrated normal coronary vessels, nevertheless continue to require cardiologic examinations and, if no one has clearly demonstrated the origin of their pain, they continue to live as invalids in constant fear of myocardial infarction. The discovery that the esophagus may be one of the causes of chest pain in these patients presenting with a previous diagnosis of "atypical" angina pectoris, unfortunately cannot resolve definitively the problem. An association of esophageal angina in patients with angina pectoris treated for long periods of time with Ca-antagonists and nitroderivatives has been described. In addition, the provocative or spontaneous tests to demonstrate the esophageal origin of chest pain give only a "likely" and not a "definite" diagnosis of esophageal angina. This also means to no "gold standard" text exist. Lastly, the "likely" diagnosis of esophageal angina is made in only about 50% of patients leaving the problem of the remaining 50% unanswered. These uncertainties induce some psychologists to assert that the cause of non cardiac angina-like chest pain is in the head ("panic disorder") and not in the esophagus, where the observed motor disorders should be an epiphenomenon.(ABSTRACT TRUNCATED AT 250 WORDS)

Agitation may be caused by respiratory insufficiency, pain, or environmental factors. Among its treatments are mechanical ventilation, comfort measures, and a variety of medications. Skillful intervention is essential to combine and monitor therapies and to wean infants from some medications.

Despite the use of modern analgesic methods and an improved use of narcotics, the combination pain-agitation sometimes persists in the recovery-room. Aconit seems to be an appropriate homeopathic treatment in this case. To prescribe it, the following conditions must be combined: violence and suddeness of the stress bringing about intense and anguish. The study included 50 children with such symptoms; it was carried out double-blind, the children being given either placebo or Aconit. Aconit proved to be effective for children's postoperative agitation with 95% good results. It is usually stated in such studies that the placebo effect is high and may reach rates higher than 30%. Aconit is an amazing cure when well prescribed, as much for the speediness of its action as for its efficiency. This remedy has a place in the recovery-room and should be in every physician's emergency case. The fundamental research could specify how the remedy works and may be discover other molecules effective for stress.

Endogenous opioid peptides have been implicated in the regulation of pain perception, behaviour, gastrointestinal activity and other physiological responses. However, the functional role of these peptides in the horse has yet to be elucidated. The opioid antagonist, naloxone, is often administered to infer endogenous opioid effects. In the present study, naloxone (0.75 mg/kg bodyweight) was administered to eight Thoroughbred racehorses and a number of behavioural and autonomic responses were measured. Naloxone produced rapid onset diarrhoea, restlessness, abdominal checking, tachycardia, tachypnoea, paradoxical yawning and diaphoresis. These responses described an acute abdominal distress syndrome similar to spasmodic colic. Results from this study suggest that, in the horse, endogenous opioids: 1) influence behaviour, 2) modify intestinal activity and sensation, and 3) if perturbed, may be involved in pathophysiology of colic.

Since children's intellectual perception is limited, the preoperative visit by an anesthesiologist alone can rarely help to free the small patients from fear and restlessness prior to elective surgery. In order to relieve anxiety which should be the primary goal of premedication in any patient - children need anxiolytic premedication agents. Drugs for premedication administered by intramuscular or rectal route in children often cause pain, fear and discomfort. The present study was performed in order to investigate oral given midazolam in the premedication of children with special regard to the practical suitability of this method. 100 children, 0.5 to 10 years of age (group A: 0.5-4 years, group B: 5-10 years) undergoing elective urological surgery received 0.4 mg/kg midazolam orally about 20 minutes prior to the arrival in the operation unit. After insertion of a venous cannula into a forearm vein anesthesia was induced with thiopental and maintained by inhalation with Isoflurane, nitrous oxide and oxygen (fi O2:0.3). Degree of sedation, state of mind and behaviour (for 100 children) as well as blood pressure and heart rate (separately for group A and B) were registered preoperatively at defined, comparable and representative circumstances. Side effects prior and during induction phase of anesthesia were documented. The personal data are representative for a normal population of children with typical urological diseases. Oral administered midazolam had only a mild or non sedative effect in 76-84% of the children 70-84% of the small patients showed an indifferent or euphoric state of mind and 67-88% behaved cooperatively or passively.(ABSTRACT TRUNCATED AT 250 WORDS)
