Intrathecal neostigmine has been used as an adjunct to intrathecal local anaesthetic or opioid to prolong regional analgesia and improve haemodynamic stability, with variable results. This meta-analysis aims to evaluate the effectiveness and side-effects of intrathecal neostigmine in the perioperative and peripartum settings. The literature search was based on Cochrane Controlled Trials Register, EMBASE and MEDLINE (from 1966 to 14 November 2003) databases. Volunteer and animal studies were excluded. We identified 26 studies and 19 were considered suitable for detailed data extraction. Intrathecal neostigmine increased the incidence of nausea and vomiting (OR 5.0, 95% CI: 3.4 to 7.3; P<0.00001), bradycardia requiring intravenous atropine (OR 2.7, 95% CI: 1.4 to 5.4; P=0.005), and anxiety, agitation, or restlessness (OR 10.3, 95% CI: 3.7 to 28.9; P=0.00001). It improved the overall 24 hour VAS score (-1.4 VAS pain score, 95% CI: -1.7 to -1.2, P<0.00001), delayed the time of first request for rescue analgesia (168 min, 95% CI: 125 to 211; P<0.00001), and reduced the total number of rescue injections of nonsteroidal anti-inflammatory drug within the first 24 hours (-0.8, 95% CI: -1.1 to -0.4; P=0. 00001). It did not affect the duration of motor blockade (3.5 min, 95% CI: -1.5 to 8.6; P=0.17) or the total amount of ephedrine required (-0.4 mg, 95% CI: -1.5 to 0.7; P=0.5). Adding intrathecal neostigmine to other spinal medications improves perioperative and peripartum analgesia marginally when compared with placebo. It is associated with significant side-effects and the disadvantages outweigh the minor improvement in analgesia achieved.

This article reviews relevant clinical issues regarding sedation, analgesia and neuromuscular blockade in the cardiac intensive care unit, including monitoring tools and available therapeutic options. The pathophysiologic implications of pain, agitation, anxiety and delirium in the ventilated patient are also discussed. Although guidelines for sedation, analgesia and neuromuscular blocking drugs in critical care have recently been published, there is great variability in clinical practice. The complexity of the environment and associated pathologies makes it difficult to implement universally applicable therapeutic regimens. Knowledge of pharmacologic mechanisms is an important tool in the development of dynamic protocols adapted to each unit. Strategies that include monitoring resources are essential for the optimization of sedation, analgesia and neuromuscular blockade.

Psychopharmacologic treatment in pediatric critical care requires a careful child or adolescent psychiatric evaluation, including a thorough review of the history of present illness or injury, any current or pre-existing psychiatric disorder, past history, and laboratory studies. Although there is limited evidence to guide psychopharmacologic practice in this setting, psychopharmacologic treatment is increasing in critical care, with known indications for treatment, benefits, and risks; initial dosing guidelines; and best practices. Treatment is guided by the knowledge bases in pediatric physiology, psycho-pharmacology, and treatment of critically ill adults. Pharmacologic considerations include pharmacokinetic and pharmcodynamic aspects of specific drugs and drug classes, in particular elimination half-life, developmental considerations, drug interactions, and adverse effects. Evaluation and management of pain is a key initial step, as pain may mimic psychiatric symptoms and its effective treatment can ameliorate them. Patient comfort and safety are primary objectives for children who are acutely ill and who will survive and for those who will not. Judicious use of psychopharmacolgic agents in pediatric critical care using the limited but growing evidence base and a clinical best practices collaborative approach can reduce anxiety,sadness, disorientation, and agitation; improve analgesia; and save lives of children who are suicidal or delirious. In addition to pain, other disorders or indications for psychopharmacologic treatment are affective disorders;PTSD; post-suicide attempt patients; disruptive behavior disorders (especially ADHD); and adjustment, developmental, and substance use disorders. Treating children who are critically ill with psychotropic drugs is an integral component of comprehensive pediatric critical care in relieving pain and delirium; reducing inattention or agitation or aggressive behavior;relieving acute stress, anxiety, or depression; and improving sleep and nutrition. In palliative care, psychopharmacology is integrated with psychologicapproaches to enhance children's comfort at the end of life. Defining how best to prevent the adverse consequences of suffering and stress in pediatric critical care is a goal for protocols and for new psychopharmacologic research [23,153].

Patients undergoing potentially painful interventional radiological procedures generally require a combination of analgesia and sedation. This sedation/analgesia should allow the patient to communicate while also remaining calm. Bispectral index (BIS) monitoring could be useful in achieving this. The primary end-point of our study was to compare the percentage time with optimal sedation, defined as Sedation Agitation Scale (SAS) grade 4, between a BIS-guided remifentanil/propofol regimen and a clinically guided regimen in 54 randomly allocated patients. The mean +/- sd percentage time with optimal sedation was significantly longer (P = 0.004) in the BIS group (76.6% +/- 14.7%) than in the SAS group (63.8% +/- 16.4%). There was a significant difference in the weighted mean infusion rates of remifentanil (P = 0.0067) and propofol (P = 0.0075) in the BIS group (0.066 +/- 0.027 microg.kg(-1) . min(-1) 1.59 +/- 0.44 mg.kg(-1) . h(-1)) compared with the SAS group (0.091 +/- 0.036 microg.kg(-1).min(-1) 1.92 +/- 0.43 mg.kg(-1).h(-1)), respectively. BIS values exhibited a temporal correlation to SAS scores (r2 = 0.72). In conclusion, a BIS-guided regimen was more effective than a SAS-guided regimen. The use of BIS resulted in fewer remifentanil and propofol doses. The targeted BIS range of 80-85 provided a sufficient functional level of sedation.

We report a case of unusual block caused by postoperative epidural analgesia for laparotomy in a gynecologic patient in consequence of inadvertent epidural catheterization. The clinical manifestation included agitation, spotty distribution of analgesia, wide spread of sensory block and loss of motor power. The radiological findings suggested a multicompartmental block with the anchorage of the catheter tip stretching over the epidural and subdural spaces. The default of catheter position was not detected during routine test dose procedure.

Cardiopulmonary resuscitation does not end with restoration of spontaneous circulation; rather, it must be continued with the application of all the measures that allow organ function to be maintained. The initial goal of hemodynamic treatment is to achieve normal blood pressure for the patient's age by means of fluids and/or vasoactive drugs. The aim of respiratory treatment is to normalize ventilation and oxygenation without causing further lung injury, avoiding hyperoxia and hyperventilation as well as hypoxia and hypercapnia. Neurological stabilization aims to reduce secondary brain damage, by avoiding hypertension and hypotension, maintaining normal ventilation and oxygenation, and treating hyperglycemia, agitation and seizures. Although no specific studies in children are available, data from adults have shown that early moderate hypothermia attenuates brain damage secondary to cardiorespiratory arrest, without increasing complications. After the arrest, the need for analgesia and/or sedation must be considered. The process of transportation to the pediatric intensive care unit (PICU) requires the following steps: stabilizing the patient, checking for and stabilizing fractures and external wounds, ensuring a stable airway and intravenous lines, assessing the need for nasogastric and bladder tubes, taking blood samples for analyses, contacting the PICU and informing the staff about the child's condition, choosing the optimal vehicle for transportation according to the child's condition and the distance, checking pediatric equipment and medications, selecting experienced staff and, finally, maintaining close surveillance and monitoring during transportation.

Effective and consistent management of neonatal pain remains a controversial issue. Premature infants are repeatedly subjected to painful tests and procedures or suffer painful conditions when they are most vulnerable. With different mechanisms transducing various types of pain the practice of 'one-drug fits all' becomes questionable. Clinicians must use the latest non-pharmacologic and pharmacologic therapies for effective management of neonatal pain, distress, or agitation. Pharmacologic strategies for dealing with neonatal pain in the neonatal intensive care unit are described. Opioid therapy, once considered the mainstay for neonatal analgesia, may not be as effective as previously thought. Morphine infusions do not alter the neurological outcomes of preterm neonates and may not be effective against acute pain. Alternative approaches with methadone, ketamine, or local anesthetics should be considered. Clinicians must understand the contextual circumstances underlying pain in individual neonates and tailor therapy accordingly, using the most current evidence related to neonatal pain assessment and management.

The pharmacokinetics and the effects of the opioid buprenorphine on behavior, cardiovascular parameters, plasma concentrations of cortisol and vasopressin were studied in the goat. After intravenous injection at a dosage of 0.02 mg/kg bw, the terminal half-life was 73.8+/-19.9 min (mean+/-SD), the apparent volume of distribution 5.22+/-1.01 L/kg, and total body clearance 79.1+/-18.5 mL/min/kg. After intramuscular administration of buprenorphine at the same dosage, bioavailability was complete and clearance was 54.7+/-16.6 mL/min/kg. Heart rate, blood pressure and concentrations of cortisol and vasopressin in plasma increased after drug administration. The goats became agitated and stopped ruminating. The effects were more pronounced the first time the animals received the drug, especially the influence on the hormone levels. The concentrations of cortisol and vasopressin in plasma remained unaffected after the second dose despite a wash-out period of 3-6 weeks. Buprenorphine may be an unsuitable drug in goats because of the profound inhibition of rumination and the agitation it causes. The short half-life of buprenorphine may limit its use if long-term analgesia is required but be advantageous if a short acting drug is desirable.
