Comparative StudyResource use in the ICU: short- vs. long-term patients.
Intensive care medicine uses a disproportionate share of medical resources, and little is known about the distribution of resources between different patient groups. ⋯ In this university-based, medical-surgical adult ICU, 11% of all patients stayed more than 7 days in the unit and consumed more than 50% of all resources. Thus, a highly disproportionate amount of resources were used per survivor in group L compared with those in group S.

Comparative StudyWarming of infusion syringes caused by electronic syringe pumps.
To evaluate inadvertent warming of the infusion syringe in four different types of electronic syringe pumps. ⋯ Infusion solutions can be significantly warmed by syringe pumps. This has potential impact on bacterial growth and the stability of drug solutions and blood products infused, as well as on the susceptibility to hydrostatic pressure changes within the infusion syringe.

Randomized Controlled Trial Clinical TrialKetamine reduces swallowing-evoked pain after paediatric tonsillectomy.
Ketamine efficacy as an analgesic adjuvant has been studied in several clinical settings with conflicting results. The aim of this study was to investigate the effect of ketamine on spontaneous and swallowing-evoked pain after tonsillectomy. ⋯ Premedication with a small dose of ketamine reduces swallowing-evoked pain after tonsillectomy in children who received an analgesic regimen combining an opioid and a NSAID.

Randomized Controlled Trial Comparative Study Clinical TrialRocuronium combined with i.v. lidocaine for rapid tracheal intubation.
Rocuronium (ORG 9426) has been shown to have an onset of action more rapid than other nondepolarizing neuromuscular blocking agents and to provide intubating conditions similar to those of succinylcholine 60-90 s after administration. We compared the intubating conditions and hemodynamic changes after the administration of rocuronium 0.6 mg kg(-1) and lidocaine 1.5 mg kg(-1) with rocuronium alone and succinylcholine 60 and 90 s after administration. ⋯ The combination of lidocaine (1.5 mg kg(-1)) and low-dose rocuronium (0.6 mg kg(-1)) along with propofol is clinically equivalent to succinylcholine, improves intubating conditions in 60 s and effectively blocks increases in heart rate after intubation.

Randomized Controlled Trial Clinical TrialCombined effects of prone positioning and airway pressure release ventilation on gas exchange in patients with acute lung injury.
Prone positioning has been shown to improve oxygenation in 60-70% of patients with acute lung injury (ALI) or acute respiratory distress syndrome (ARDS). Another way to improve matching of ventilation to perfusion is the use of partial ventilatory support. Preserving spontaneous breathing during mechanical ventilation has been shown to improve oxygenation in comparison with controlled mechanical ventilation. However, no randomized studies are available exploring the effects of preserved spontaneous breathing on gas exchange in combination with prone positioning. Our aim was to determine whether the response of oxygenation to the prone position differs between pressure-controlled synchronized intermittent mandatory ventilation with pressure support (SIMV-PC/PS) and airway pressure release ventilation with unsupported spontaneous breathing (APRV). ⋯ APRV during prone positioning is feasible in the treatment of ALI patients. APRV after 24 h appears to enhance improvement in oxygenation in response to prone positioning.
