A patient acceptability study was conducted using patient-controlled intranasal diamorphine. Patients undergoing nonemergency orthopaedic or gynaecological surgery self-administered intranasal diamorphine for 24 h postoperatively. Pain, pain relief, sedation, respiratory rate, nausea and vomiting were assessed regularly. After 24 h, patients and their attending nurses completed a questionnaire assessing satisfaction and practical aspects of the technique. Satisfaction was reported as good or complete by 69% of patients and 69% of nurses. Pain relief was assessed as better than expected by 45% of patients and better than normal by 50% of nurses. Seventy-nine per cent of patients would be pleased to use patient-controlled intranasal diamorphine again and 89% of nurses would be happy for their patients to use it again. Sedation was uncommon and mild and there were no episodes of significant respiratory depression. Fifty-three per cent of patients reported no nausea and 74% did not vomit at any stage. There were seven withdrawals, four due to problems with the device and three due to therapeutic problems. The nasal spray may need modification to improve reliability. However, we found patient-controlled intranasal analgesia an effective technique, which was well tolerated by patients and nurses and was without unpleasant side-effects. Further work to determine how it performs compared with intramuscular or intravenous analgesia is now needed.

Sedation allows patients to tolerate unpleasant procedures while maintaining adequate cardiorespiratory function and the ability to respond purposefully to verbal command. For ophthalmic surgery patient's anxiety and discomfort can be relieved during placement of a peribulbar block and during surgery by intravenous sedation. Intravenous sedation should only be administered by an anesthetist. Three different classes of drugs are used for intravenous sedation: analgesics (fentanyl and alfentanil), benzodiazepines (midazolam) and profofol, an intravenous anesthetic. Sedation may result in ventilatory, cardiovascular and neurologic complications. Excessive sedation can induce hypoventilation from central ventilatory depression or airway obstruction. Uncontrolled and unexpected movements of the head could result in major surgical complications. For the prevention of the complications related to sedation the same monitoring as for general anesthesia is essential.

The study assessed the dosage, clinical sedative effect, and safety of intranasal midazolam in 32 children. Data were complete for 29 patients (21 with lacerations and 8 cases of dental trauma). Sedation was adequate to ensure successful completion of treatment under local with or without topical anaesthetic in 22 of the 29 cases (76%). They became sedated at a mean (SD) of 14 (5) minutes, with completion of treatment at 20 (13) minutes. Sedation was achieved with a mean (SD) of 5 (2)mg of midazolam. There were no signs of respiratory depression or of oxygen desaturation below 94% on pulse oximetry. No supplemental oxygen was required and there were no other complications. We conclude that intranasal midazolam is a safe and effective alternative to general anaesthesia in the definitive treatment of children with oral and maxillofacial injuries.

The present study evaluated self-reported subjective complaints (29 single items and 11 scales) at precessation, on quit day, and on Days 1, 2, 3, 7, 14, 21, and 28 after cessation in 46 healthy quitters who remained abstinent for the first month after cessation (biochemically confirmed). Also tested on the same schedule were 29 nonsmokers matched for age and gender. Specific criteria were set for transient and offset effects based on the direction, magnitude, and time course of changes in symptoms after cessation. Results indicated that single-item anger, anxiety, depression, difficulty concentrating, irritability, restlessness, dizziness, and nausea, and the Shiffman-Jarvik Stimulation/Sedation Subscale, the Perceived Stress scale, and the POMS anger, confusion, and tension subscales met the criteria for transient effects, and that single-item desire to smoke, cough, and headache, and the Shiffman-Jarvik Psychological Subscale met the criteria for offset effects. These findings help to clarify which subjective complaints after smoking cessation are transient effects and which are offset effects, a distinction with important implications for understanding nicotine dependence and for designing pharmacological and nonpharmacological interventions for smoking cessation.

Sedation for children doing diagnostic or operative pediatric gastrointestinal endoscopy (PE) procedures is performed differently over the world and no consensus is yet agreed on the best paediatric endoscopy sedation (PES). Some centres do not use any sedation, especially in infants, most centre use some form of sedation: conscious sedation, deep sedation and general anaesthesia. We review sedation drugs and describe our centre protocol on 188 consecutive PE: oral premedication with flunitrazepam (0.05 mg/kg/dose) at least 30 min before procedure, petidine (1 mg/kg) followed by increasing boluses of midazolam (0.05 mg/kg up to a maximal 0.2 mg/kg or 5 mg) were given i.v. to obtain a conscious sedation. All PE could be performed and ended safely, PES resulted satisfactory in approximately 65% of patient having conscious sedation. SaO2 < 90% was observed in 2% of cases, one child had a respiratory depression after PE that resolved with flumanezil. Endoscopy and sedation was always performed by the PE team in the immediate vicinity of anaesthesiologists at work. PE can be safely performed with conscious sedation. Basic and advanced resuscitation skills are needed for the PE team who wish to perform both endoscopic and sedation procedures.

Sedation has been commonly used in the neonate to decrease the stress and pain from the noxious stimuli and invasive procedures in the neonatal intensive care unit, as well as to facilitate synchrony between ventilator and spontaneous breaths. Fentanyl, an opioid analgesic, is frequently used in the neonatal intensive care unit setting for these very purposes. Various reported side effects of fentanyl administration include chest wall rigidity, hypotension, respiratory depression, and bradycardia. Here, 2 cases of urinary bladder retention leading to renal pelvocalyceal dilatation mimicking hydronephrosis as a result of continuous infusion of fentanyl are reported.

BACKGROUND: The administration of sedatives in terminally ill patients becomes an increasingly feasible medical option in end-of-life care. However, sedation for intractable distress has raised considerable medical and ethical concerns. In our study we provide a critical analysis of seven years experience with the application of sedation in the final phase of life in our palliative care unit. METHODS: Medical records of 548 patients, who died in the Palliative Care Unit of GK Havelhoehe between 1995-2002, were retrospectively analysed with regard to sedation in the last 48 hrs of life. The parameters of investigation included indication, choice and kind of sedation, prevalence of intolerable symptoms, patients' requests for sedation, state of consciousness and communication abilities during sedation. Critical evaluation included a comparison of the period between 1995-1999 and 2000-2002. RESULTS: 14.6% (n = 80) of the patients in palliative care had sedation given by the intravenous route in the last 48 hrs of their life according to internal guidelines. The annual frequency to apply sedation increased continuously from 7% in 1995 to 19% in 2002. Main indications shifted from refractory control of physical symptoms (dyspnoea, gastrointestinal, pain, bleeding and agitated delirium) to more psychological distress (panic-stricken fear, severe depression, refractory insomnia and other forms of affective decompensation). Patients' and relatives' requests for sedation in the final phase were significantly more frequent during the period 2000-2002. CONCLUSION: Sedation in the terminal or final phase of life plays an increasing role in the management of intractable physical and psychological distress. Ethical concerns are raised by patients' requests and needs on the one hand, and the physicians' self-understanding on the other hand. Hence, ethically acceptable criteria and guidelines for the decision making are needed with special regard to the nature of refractory and intolerable symptoms, patients' informed consent and personal needs, the goals and aims of medical sedation in end-of-life care.

Psychosis only rarely occurs in patients with untreated Parkinson's disease. Much more commonly, psychosis is induced by drug therapy for Parkinson's disease and is the strongest known risk factor for nursing home placement. Delusions are less frequent than hallucinations, but are more concerning as they are often paranoid in nature. Treatment begins with a search for correctable infectious, toxic, and metabolic aetiologies. If symptoms persist, anti-Parkinson's disease medications are slowly reduced. However, withdrawal of these drugs usually worsens parkinsonism and is often not tolerated. Certain atypical antipsychotics can be used to treat psychosis without compromising motor function. The choice of atypical antipsychotic is largely based on ease of use and adverse effect profile as most have comparable efficacy in improving psychosis. Currently, there are five marketed atypical drugs - clozapine, risperidone, olanzapine, quetiapine and ziprasidone. Ziprasidone is the only agent whose adverse effect profile has not been reported in Parkinson's disease. The most common adverse effects of clozapine in Parkinson's disease are sedation, orthostatic hypotension and sialorrhoea. Sedation is generally helpful since these patients are frequently awake at night and tend to have worse behavioural problems then. Clozapine does not induce deterioration of motor function, but it has the potential to cause agranulocytosis, which is idiosyncratic and not dose-related. In risperidone-treated Parkinson's disease patients, reported adverse effects include somnolence, sialorrhoea, dizziness, palpitations, constipation, delirium, fatigue, leg cramps, depression, urinary incontinence and hypotension. Although in some Parkinson's disease studies, risperidone has been well tolerated, others have shown that many patients are unable to tolerate the drug due to deterioration of motor function. While an initial study of olanzapine in Parkinson's disease psychosis showed the drug to be effective without deterioration of motor function, succeeding reports demonstrated a deleterious effect of the drug on motor functioning. The most common adverse effects of quetiapine in Parkinson's disease patients are sedation and orthostatic hypotension. There is a lack of double-blind trials; however, cumulative reports involving >200 Parkinson's disease patients strongly suggest that quetiapine is well tolerated and effective. Unlike clozapine, it does not improve tremor and may induce mild deterioration of motor function. Recently, cholinesterase inhibitors have been reported to alleviate psychosis in Parkinson's disease. Although ondansetron, an antiemetic with antiserotonergic properties, has been reported to relieve psychosis in Parkinson's disease, its prohibitive cost has prevented further study in this population. Electroconvulsive treatment is generally reserved for the patient with psychotic depression who is unable to tolerate any pharmacological therapy.

Sedation is a property of many psychotropic drugs. It can be defined as a decrease in psychomotor and cognitive performance. Many of the earlier neuroleptic, anxiolytic, antidepressant and antihistamine drugs were extremely sedative and sedation came to be considered as an integral part of the activity of these compounds. Newer, far less sedative, examples of each of these classes have shown that sedation is not required for their efficacy. Sedation is now increasingly considered as an adverse effect which should be avoided rather than a desirable effect especially when treating disorders such as anxiety or depression. This article discusses the sedative properties and mechanisms of different classes of psychotropic drugs.

Diazepam rectal gel (Diastat) is the only medication approved by the US FDA for the management of selected, refractory patients with epilepsy, on stable regimens of antiepilepsy drugs, who require intermittent use of diazepam to control bouts of increased seizure activity. An analysis of the safety of diazepam rectal gel reveals that this formulation has certain advantages over intravenous diazepam administration: most notably a very low incidence of respiratory depression, low potential for abuse and the opportunity for out-of-hospital use by non-professional caregivers. Sedation is the most common adverse effect of rectal diazepam treatment, occurring in approximately one-quarter of patients, although drug-induced somnolence is difficult to distinguish from normal post-ictal sedation. Overdosage of diazepam rectal gel is rarely associated with serious clinical consequences, and overdoses of up to 330% of the maximum recommended dosage have been reported without any respiratory or cardiac depression. Under-administration may be a serious safety issue because of morbidity that may result if seizures are not terminated. Chronic administration may cause tachyphylaxis and should be avoided.
