Dantrolene should be repeated after 5—8 hr. Bicarbonate, procaine amide, and other drugs should be repeated as needed. Treatment of disseminated intravascular coagulation is symptomatic. Early diagnosis and treatment ofMH is essential. After effective treatment, the patient should be watched closely in the intensive care unit for recurrence of MH, myoglobinuric renal failure, disseminated intravascular coagulation, muscle weakness, and electrolyte imbalance. 

In patients hospitalized because of asthma, patient-initiated (on-demand) therapy may result in decreased nebulized doses, decreased adverse effects, and shorter hospital stays than ther-apy given regularly at 4-hour intervals.20 In patients admitted to the intensive care unit and placed on mechanical ventilation, P2-agonists can be delivered via an MDI or nebulization through the ventilatory circuit. 

The immediate effect of increasing intracellular cAMP levels is an increase in contractility. This has been observed repeatedly in acutely ill patients in the intensive care unit with the intravenous infusion of either (3-adrenergic agonists (e.g., dobutamine) or the phosphodiesterase inhibitors milrinone (Corotrope) and am-rinone (Inocor). Binding of dobutamine to cardiac myocyte adrenoceptors results in G-protein coupling, activation of adenylyl cyclase, and the conversion of ATP to cAMP. 

Vecuronium has an elimination half-life of about one hour (Table 6.4) and is metabolised to 3-, 17-, and 3,17-hydroxy metabolites, the main route of elimination being via the liver. The metabolites have potent neuromuscular blocking action and are eliminated by the kidneys. As a result, the effects of vecuronium are prolonged in hepatic and renal disease. The metabolites may be responsible for cases of prolonged paralysis seen after long-term administration of vecuronium to patients in intensive care units. The effects of vecuronium are also prolonged in the elderly and in hypothermia due to the kinetic factors. 

This drug has sedative and anticonvulsant properties. Its use in anaesthesia is now almost exclusively reserved for the management of acute withdrawal syndromes in the intensive care unit. It is thought that clomethiazole enhances GABAergic transmission in the brain. At normal dosages it has little effect on the cardiovascular system. 

Haloperidol is used as an antipsychotic and occasionally for control of acute agitation in the intensive care unit. It is can also be useful in the treatment of phencyclidine abuse. It produces a cataleptic state with little drowsiness and has minimal effects on blood pressure and respiration. It is a long-acting drug with a half-life of about 18 hours. It is available in oral and injectable preparations. In large doses extrapyramidal side effects may occur. 

Cisatracurium Similar to tubocurarine Like tubocurarine but lacks histamine release and antimuscarinic effects Prolonged relaxation of surgical procedures relaxation of respiratory muscles to facilitate mechanical ventilation in intensive care unit Not dependent on renal or hepatic function duration, 25-45 min Toxicities Prolonged apnea but less toxic than atracurium... 

Emergency treatment depends on the immediate toxic effects of BZP and TFMPP. High blood pressure, abnormal heart rate or rhythm, seizures or convulsions, fever, and abnormal movements all have specific treatments and may require hospitalization for intravenous medications and general supportive care. Coma or decreased level of consciousness, respiratory depression, difficulty breathing, and severe allergic reaction may require treatment in an intensive care unit and assisted respiration. If a user experiences any untoward effects, or if someone inadvertently takes a much larger dose of medicinal piperazines than prescribed, it is prudent to contact a doctor, emergency medical services, or poison control. 

Chest pain during septal ablation commonly occurs and is effectively managed by analgesic therapy. Intensive care unit monitoring is employed routinely postprocedure in anticipation of ventricular arrhythmias during the initial period of myocardial injury, Prophylactic antiarrhythmic therapy has not been used in our center,... 

The good agreement between sensor and laboratory results proves the effectiveness of the pre-calibration procedure and sensor stability. The results suggest that these devices can be used for short term glucose-lactate monitoring in for example the intensive care unit, the operation theater, in sports, medicine, rehabilitation and in diabetology. 

Death due to the use or misuse of ketamine is rare. Only severe overdoses present substantial risk, and such incidents are usually treated in the intensive-care unit. The most dangerous effects of ketamine are behavioral. Individuals may become withdrawn, paranoid, and very uncoordinated. Physicians can only treat overdoses of this type symptomatically, by offering calm reassurance and an environment with little stimulation. 

The withdrawal of an infusion of midazolam, used as sedation in intensive care units, is associated with occasional severe and bizarre behavioral disturbances, particularly in children (50). These are similar in nature to the withdrawal effects seen with other short-acting benzodiazepines. 

Burn Center Care Is the Most Efficient and Cost-Effective Care for Burn Injuries. Burn injuries are not like other trauma injuries burn injuries often require a lengthy course of treatment as compared with simple or even complex trauma patients. For example, for burn patients with 50% body surface area burn, the average length of stay in the intensive care unit is 50 days. In a mass casualty, the average burn is typically greater than 50% body surface area. 

In a severe pandemic, the need for mechanical ventilators may far exceed hospital and Strategic National Stockpile (SNS) reserves. Using the CDC s FluSurge modeling software to predict the effects of DHHS planning assumptions for a severe pandemic, it can be predicted that in a typical city, with a pandemic of moderate duration and attack rate (8 weeks and 25 % respectively), at pandemic peak (Week 5), flu patients would require 191% of all non-intensive care unit (ICU) beds, 461% of all available ICU beds, and 198% of all available mechanical ventilators (Toner, 2005, December I). Even with greatly increased reserves, the SNS will not be able to provide supplies of ventilators adequate to meet the needs of hospitals in a pandemic. Moreover, they will not be able to rent equipment, and it is not practical for hospitals to purchase, maintain, and store expensive full feature mechanical ventilators just to have them on hand in case they are needed.

However, because a continuous infusion is required, implantable pumps containing a very concentrated solution of baclofen are used to avoid frequent refills. Inadvertent subarachnoid bolus administration of a concentrated solution will produce cranial spread of baclofen within the CSF, resulting in cerebral effects. This is most hkely to occur when a new catheter or pump is implanted or during surgical revision of a catheter or implantable pump in cases of malfunction. A report of coma after implantation of a baclofen pump in five out of nine consecutive children illustrates this (3). The authors suggested that these children should be monitored in the recovery room for 5 hours postoperatively, in order to cover both the peak effect of any baclofen bolus and the additive effects of other perioperative CNS suppressants, such as opioids, benzodiazepines, or sedative antiemetics. In another report of transient coma after perioperative intrathecal bolus administration it was shown that the management of this complication can require admission to an intensive care unit (4). 

There was an unexpectedly high frequency of adverse effects in a pediatric intensive care unit with the combination of high-dose phenobarbital and beta-lactam antibiotics, mainly cefotaxime (353). The reactions, which mostly affected the skin and blood, were only rarely reproduced by a single component, suggesting an interaction. However, these findings have not been confirmed, and their impact is unclear. 

The pharmacokinetics of intravenous ciprofloxacin have been studied in intensive care unit patients during continuous venovenous hemofiltration (n — 5) or hemo-diafiltration (n — 5) (67). Ciprofloxacin clearance was not altered. A dosage of 400 mg/day was sufficient to maintain effective drug plasma concentrations in patients undergoing continuous renal replacement therapy. 

The H2 receptor antagonists do not prevent gastroduodenal ulceration by non-steroidal anti-inflammatory drugs, but they do prevent stress-induced ulceration and bleeding. In intensive care units there is evidence of a beneficial effect, but in patients with hematemesis and melena there is little evidence that H2 receptor antagonists reduce rates of transfusion, surgical intervention, or mortality (SEDA-19, 326).
