Sedation and tiredness are among the most frequent symptoms among cancer patients. A detailed assessment of these symptoms is necessary to evaluate therapeutic effects, such as the use of methylphenidate or comparison of different opioids. The Brief Fatigue Inventory (BFI) has been validated as a short and comprehensive instrument to assess severity of fatigue and fatigue-related impairment in cancer patients. We validated the German version of the BFI in patients with chronic cancer-related and noncancer-related pain treated in a tertiary pain center. Patients treated in the Pain Clinic of the Department of Anesthesiology completed the BFI, the minimal documentation system (MIDOS) and the short form SF-36 quality-of-life questionnaire (SF-36). Test-retest reliability was assessed with a second BFI immediately after the consultation and in a subgroup of patients after 3 to 7 days. Nineteen percent of the 117 patients were treated for cancer-related pain (C); the other patients suffered from chronic severe pain of nonmalignant origin (NC). Patients reported mean values for average fatigue of 3.9 (C) and 4.9 (NC), and for worst fatigue of 5.5 (C) and 6.2 (NC). The mean score of the 6 impairment items was 4.3 in both groups. Factor analysis led to a solution with one common factor for all nine items. Fatigue on the BFI correlated highly with 'feeling tired' in the SF-36 and with 'sedation' in MIDOS, and less with 'being worn out' in SF-36 and 'weakness' in MIDOS. Internal consistency was high, as was test-retest reliability, with a correlation of the intensity, mean scores of 0.93 and the impairment mean scores of 0.87. In conclusion, we found the German version of the BFI to be reliable and valid for cancer and noncancer patients. Minor differences were seen in the validation compared to the original version.

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.

Adequate early assessment of brain damage is essential. Location, extension and severity of structural damage affect brain function and ultimately determine the outcome. The extent of functional impairment, and the morphology of intracranial lesions, require specific treatment, often a combination of medical and surgical interventions. Brain damage usually evolves over time, and repeated assessments are necessary. Clinical evaluation is often biased by concomitant sedation and/or anesthesia, but remains necessary. A revision of the literature is presented. Brain damage is assessed combining clinical and instrumental data. Clinical examination is performed assessing the 3 components of the Glasgow Coma Scale. Spontaneous or stimulated (pain stimulus) eye opening, verbal and motor responses are observed after hemodynamic and respiratory stabilisation. Unfortunately a significant proportion of patients can not be properly examined for several reasons: eye opening can be altered by palpebral and facial injuries, verbal response can be impaired by maxillo-facial injuries or by endotracheal intubation, and motor response remains the most consistent parameter. Sedation, analgesia and myorelaxants, however, can profoundly diminish or abolish the motor response to maximal stimulation, so that examination should be performed after clearance of drugs. Often alcohol or other substances can further impair the neurological performances. Pupils diameter and reactivity to light should be observed, excluding pharmacologic effects (as dilation due to catecholamines) and direct ocular or orbital damage. The CT scan is necessary for disclosing surgical masses and for identifying the extent of diffuse damage and the location of focal lesions. These data should be combined with additional functional exploration, as provided by cerebral extraction of oxygen and electrophysiologic data. Early estimation of cerebral damage is complex and prone to mistakes. Accurate, repeated evaluations, based on the combination of clinical observation and imaging, are necessary.

Purpose of the study was to evaluate efficacy and safety of conscious sedation in ambulatory pediatric surgery. During 50 settings 38 patients were administered 0.75 mg/kg Ketamine and 0.4 mg/kg Midazolam rectally prior to the diagnostic or therapeutic procedure. Effects on vital signs, anxiolysis and pain reduction were documented. Side effects and complications were assessed. Satisfaction of patients and their parents were evaluated separately. Conscious Sedation can been administered safely by the physician, even in the absence of anesthesiological colleagues, as long as the correct indication is taken account of and only well established analgetics in standardised doses are given. Furthermore the intervention needs to take place in a well-organised setting. Advantages of the procedure are a cooperative patient with stable vital signs with the patients themselves and their parents profiting from stress-reduction through amnesia and effective pain management.

Preliminary reports have demonstrated that the application of local heat to the transdermal fentanyl patch significantly increased systemic delivery of fentanyl. The objective of this study was to further evaluate the pharmacokinetic effect of local heat administration on fentanyl drug delivery through the transdermal fentanyl patch delivery system in volunteers. In addition, the study was intended to document the effect of heat on steady-state transdermal fentanyl delivery. This was an open, 3-period, crossover study that evaluated the pharmacokinetics and safety of 25 microg/h transdermal fentanyl administered with and without local heat. During Sessions A and B, subjects received transdermal fentanyl for a 30-hour period. During Session A, heat was applied for 1 hour at the 24-hour time point during the 30-hour period. During Session B, heat was applied for the first 4 hours and then again for 1 hour at the 24-hour time point during the 30-hour period. The order of Sessions A and B was randomized, and a minimum of 2 weeks separated the sessions. Five of the 10 subjects returned to participate in Session C. During Session C, subjects received transdermal fentanyl 25 microg/h for 18 hours. Heat was applied during the first 4 hours of administration and then again for 15-minute periods at the 12- and 16-hour time points. Arterial blood samples for determination of serum fentanyl concentration were collected. Maximum concentration (C(max)), time to maximum concentration (t(max)), and area under the curve (AUC) were determined for each treatment period. Sedation, vital signs, oxygen saturation, and adverse events were recorded. During a period of 36 hours, there were no significant differences in C(max), AUC, or T(max) between transdermal fentanyl delivery with no heat and heat. However, significant differences were seen during the first 4 hours, with C(max) and AUC values almost 3 times higher for the heated administrations than for the administrations without heat. With heat, the mean C(max) was 0.63 ng/mL compared with a C(max) of 0.24 ng/mL without heat (P =.007). With early heat, the mean AUC was 1.22 ng/mL. h compared with 0.42 ng/mL. h without heat (P =.003). There was no statistically significant difference between the median times to achieve peak values (T(max)) during the first 4 hours. The addition of heat at 24 hours resulted in rapid increases in serum fentanyl concentrations for both groups and higher serum fentanyl concentrations for the administration that did not receive heat previously. Applying heat for 15 minutes at the 12-hour and 16-hour time points produced a rapid but short duration increase in serum fentanyl concentrations. The results suggest controlled heat might be used to significantly shorten the time needed to reach clinically important fentanyl concentrations. Controlled heat might be useful to produce rapid increases in serum concentrations for the rapid treatment of breakthrough pain.

Patient controlled analgesia (PCA) helps patients to achieve a better comfort both at rest and when dynamic pain is concerned. This aim can be reached by closing the feedback loop in a shorter time. The purpose is to keep drug concentration in the narrow therapeutic range of MEAC (minimal effective analgesic concentration). Two methods of administration can be used: demand bolus; continuous infusion rate plus demand bolus. Continuous infusion method together with opioids administration increases lethal complications 0.28 to 1.08% (p<0.05), unless patient controlled epidural analgesia (PCEA) is performed. Therefore, this method can be used only in ICU environment. An effective and safe dose delivering and a correct infusion timing is now possible due to recent improvement in technology. The success in PCA depends more by parameters chosen, patient and healthcare personnel compliance, monitoring of S(p)O(2), respiratory rate, pain VAS and Sedation Score than by the drug administered. There is recent evidence that PCA improves patient's comfort, but does not reduce the amount of personnel work, postoperative morbidity, analgesic consumption and costs.

Oral doxepin rinse has been reported to provide pain relief in patients with oral mucosal lesions due to cancer or cancer therapy. The purpose of this study was to assess the anesthetic effect of doxepin oral rinse in normal subjects to identify the duration of effect and to contrast the anesthetic effect with reported pain relief in patients with oral mucosal lesions. Normal volunteers were provided a solution of doxepin (5 mg/mL) for oral rinsing. Oral numbness and adverse effects were recorded for a period of 4 h after rinsing. Doxepin rinse resulted in mucosal anesthesia in all subjects. Sedation/fatigue was reported in four of seven subjects. There were no taste complaints and no nausea reported. The limited duration of numbness/anesthesia in normal subjects compared with prior studies showing pain relief for more than 3 h in patients with mucosal lesions, suggests that the extended duration of pain relief in patients was due to analgesic effects rather than anesthetic effects. The majority of normal subjects reported sedation after use, but this was less common in patients with mucosal lesions.

This study was performed to clarify the analgesic effect of ketamine injected into the first intercoccygeal (Co1-Co2) epidural space in standing cattle. Five adult cows were randomly received 3 treatments at least 1 week interval: 5, 10 and 20 mL of 5% ketamine. Sedation, analgesia, ataxia and other effects on cardiopulmonary and rumen functions were assessed before ketamine administration and until 120 min. The analgesia without sedation was shown at tail and perineum about 5 min after all three treatments. The duration of analgesia was significantly increased according to the volume of ketamine (p<0.01). There was a similar tendency of ataxia with individual variation. There were minimal effects on cardiopulmonary and rumen functions. The present study showed that caudal epidural ketamine administration induced analgesia without sedation in cows, and the duration of analgesia was dose dependent with ataxia. However, the duration of analgesia after 5 and 10 mL ketamine administration is short for common surgical procedures and pain relief of perineum. Further studies are needed to prolong the duration of analgesia without side effects.

Living liver donors for adult liver transplant recipients undergo extensive liver resection. Partial donor hepatectomies may alter postoperative drug metabolism and hemostasis; thus, the risks and the benefits of pain management for this unique patient population may need to be reassessed. The safety and efficacy of combined epidural analgesia and field infiltration in our initial living liver donor group are presented. A thoracic epidural catheter was placed before general anesthesia in 2 female and 6 male donors (44.2 +/- 11.3 years old, mean +/- standard deviation [SD], range 26-56). At the end of surgery, incisions were infiltrated (bupivacaine 0.25%), and an epidural infusion was used (bupivacaine 0.1% + hydromorphone hydrochloride 0.02%). Clinical outcomes were followed for 5 days. The time sequence of pain intensity on a 0-10 visual analog scale clustered into 3 phases, the intensity of which differed significantly from each other (2.2 +/- 0.6, 0.69 +/- 0.2, and 2.37 +/- 0.3 respectively, P = 0.028). Right shoulder pain was observed in 75% of the donors. Sedation, pruritus, and nausea were minimal. Consistently maximal international normalized ratio elevation occurred at 17.6 +/- 7 hours postoperatively, then slowly declined. Platelet counts were lowest on day 3. No neurologic injury or local anesthetic toxicity was observed. This 2-site approach provided effective, safe, postoperative analgesia for our donors. Universally, coagulopathy ensued, indicating a potentially increased risk for epidural hemorrhage at epidural catheter removal and mandating close postoperative neurologic and laboratory monitoring. Research is needed to advance the understanding of postoperative coagulopathy and hepatic dysfunction in these donors to further optimize their perioperative management, including that of analgesia.

Provision of optimum comfort control to a critically ill child, in Pediatric Intensive Care Unit (PICU) requires a great degree of skill and planning and should be a prime concern for all practising paediatricians. Failure to provide adequate sedation and analgesia to control the stress response has been seen to be associated with increased complications and mortality. Sedation/analgesia in PICU is required both for, short term procedure and as an adjunct to pediatric intensive care. One has to identify the requirement whether sedation, analgesia or both. The ideal approach should be a sedative/hypnotic for sedation, an anxiolytic for anxiety, and an analgesic for pain. Threfore, it is essential, to provide the right drug for the problem at the right time in the right dosage. The drugs commonly used for sedation analgesia in PICU and their side effects have been described here.
