Abstract

Measurement of maximal inspiratory pressure (MIP) is used in adults to assess respiratory muscle strength prior to extubation. The objective of this study was to define normal values for MIP in intubated children, correlate them with anthropometric variables and investigate the reliability and reproducibility of the technique. MIP was studied immediately prior to extubation in 65 mechanically ventilated, non-sedated children ready for extubation, without any heart, lung, chest wall or neuromuscular disease. No correlation between age, height and weight and MIP was observed. Intra- and inter- patient coefficients of variation in test performance was low. Patient's MIP was achieved after a mean of 2.95 maneuvers. All patients were weaned successfully from ventilator support. Measurement of MIP in intubated children is a reliable and reproducible technique also in small children who are unable to cooperate. Reference normal values are presented.
