Monitoring sedation, agitation, analgesia, neuromuscular blockade, and delirium in adult ICU patients.
Preliminary evidence suggests that closely monitoring sedation may have a positive effect on patient outcomes, including reductions in intensive care unit (ICU) stay, duration of mechanical ventilatory support, and number of diagnostic tests requested to assess central nervous system function. In the last few years, subjective instruments to assess agitation and sedation have been developed and tested for reliability and validity, including the Sedation-Agitation Scale and the Motor Activity Assessment Scale. ⋯ Promising techniques for objective assessment of sedation (such as the bispectral index) and strategies to guide neuromuscular blockade with train-of-four (TOF) or clinical exam monitoring have emerged. Future efforts should focus on evaluating the impact of these monitoring techniques on specific outcomes in an effort to improve patient comfort, minimize adverse events, and reduce resource consumption.

Infants usually respond differently to a neuromuscular relaxant compared to children or adults. Isoflurane is commonly used as an anesthetic gas in infants. In an RCT design, we investigated whether a dose of mivacurium 250 &mgr;g/kg results in faster onset of action than 200 &mgr;g/kg in infants under isoflurane anesthesia. Spontaneous recovery times and cardiovascular response were also evaluated. ⋯ The maximal effect of mivacurium 250 &mgr;g/kg, in infants under isoflurane anesthesia, was present one minute faster than 200 &mgr;g/kg. However, it produced a significant cardiovascular response.

To investigate the frequency, predisposing factors, clinical presentation, and outcome of abdominal compartment syndrome (ACS) in critically ill pediatric patients. DESIGN: A prospective study over a 5-yr period. SETTING: Pediatric intensive care unit of a tertiary care, university hospital. PATIENTS: All patients admitted to the pediatric intensive care unit were screened for the presence of ACS and were treated with a uniform protocol. ACS was defined as abdominal distention with intra-abdominal pressure (IAP) > 15 mm Hg, accompanied by at least two of the following: oliguria or anuria; respiratory decompensation; hypotension or shock; metabolic acidosis. MEASUREMENTS AND MAIN ⋯ Although relatively infrequent compared with adults, ACS occurs in critically ill children. Timely decompression of the abdomen results in uniform improvement, but overall mortality is still high. In contrast with adults, children with ACS have diverse primary diagnoses, with a significant number of primary extra-abdominal-mainly central nervous system-conditions. Ischemia and reperfusion injury appear to be the major mechanisms for development of ACS in children. Clinical presentation is similar to adults, but children may develop ACS at a lower IAP (as low as 16 mm Hg).

Comparison of resource utilization and outcome between pediatric and adult intensive care unit patients.
To compare resource utilization and outcomes between cohorts of pediatric and adult intensive care unit (ICU) patients from a single institution. DESIGN: Prospective, observational cohort study. SETTING: A large, urban, tertiary care medical center. PATIENTS: A total of 780 patients consecutively admitted to the pediatric ICU, adult medical ICU, and adult surgical ICU. MEASUREMENTS AND MAIN ⋯ Pediatric critical care patients have better short-term and longer-term survival compared with adult patients. The difference in survival is accounted for by the lower survival of adult medical patients. Despite the survival differences, pediatric and adult ICU patients incur similar hospital costs, and the proportions of patients who receive active ICU interventions are similar.

Few health care professionals realize that topical anesthetic spray can cause methemoglobinemia. We describe a 56-year-old woman who was transferred to our emergency department when severe cyanosis and chest pain developed after administration of topical oropharyngeal benzocaine and lidocaine during outpatient endoscopy. ⋯ This article presents a detailed discussion of the pathophysiology, diagnosis and treatment of methemoglobinemia, as well as a qualitative systematic review of the English literature on methemoglobinemia induced by topical anesthetic. The implications of this condition for emergency physicians are also outlined.
