RESUMEN

PURPOSE: A new semi-continuous thermodilution cardiac output (CCO) system has been developed recently (Opti-Q and Q-vue Abbott critical care system). The aim of this study was to compare the accuracy and reproducibility of this new device with conventional ice-bolus thermodilution cardiac output (BCO). METHODS: Fifteen critically ill patients who needed pulmonary artery catheterization were prospectively investigated. Eighty seven paired data using BCO and CCO methods were compared. Reproducibility was assessed from 90 BCO and 87 CCO determinations by calculation of the mean standard error (SEM) and according to Bland and Altman methodology. RESULTS: The BCO and CCO ranged from 2.46 to 11.20 L.min-1 and from 1.75 to 10.05 L.min-1 respectively. Bias (mean difference between BCO and CCO) was null (0.002 L.min-1, P = 0.98), precision (SD of the bias) was 0.74 L.min-1 and the limits of agreement (mean difference +/- 1.96 SD) ranged from -1.45 to 1.45 L.min-1. The threshold to consider two cardiac outputs as different (3 x SEM) was equivalent for BCO and CCO (0.54 and 0.465 L.min-1 respectively). According to the Bland and Altman method, reproducibility of CCO was greater than that of BCO; bias of repeated measurements of BCO and CCO were 0.15 L.min-1 (P < 0.05) and 0.047 L.min-1 (NS), respectively. CONCLUSION: Compared with BCO, this new device was accurate but cannot be considered as interchangeable regarding the limits of agreement. Reproducibility of CCO was superior to BCO.

RESUMEN

The development of patient controlled analgesia (PCA) in children is the result of a search for an analgesia being both maximally efficient and secure, in the management of severe pain. The technique is based on self infusions of an analgesic, mainly morphine, by the child, through a special pump. The quality of the pump is essential in order to exclude any risk of overdosage. In order to prevent potential secondary effects and complications, a careful supervision is mandatory (clinical, by pulse oximetry, regular checking of pump parameters). PCA is applicable to children older than 5 years. The main indications are post-operative and oncological pains.
