Visceral pain is one of the most common forms of pain and for which new drugs would be welcome. The aim of this study was to investigate whether gabapentin inhibits induced abdominal contractions in mice and to examine the effect of its co-administration with morphine. ⋯ These data demonstrated the comparable efficacy of gabapentin with morphine in visceral pain. Also, the results showed that the combination of doses of gabapentin and morphine, which were ineffective alone, produced a significant analgesic effect in the writhing model of pain. This may be clinically important in the management of visceral pain.

Despite recent advances in intensive care medicine, acute lung injury and its more severe form, acute respiratory distress syndrome pose major therapeutic problems. While mechanical ventilation is integral to the care of these patients, its adverse consequences including ventilator-induced lung injury are determinants of disease progression and prognosis. ⋯ Intensivists should be trained to recognize acute lung injury and acute respiratory distress syndrome and encouraged to use low-tidal-volume ventilation in clinical practice. Alternative modes of ventilation such as high-frequency ventilation and prone position should be reserved for selected patients in whom conventional lung-protective ventilation strategies have failed.

We have previously demonstrated, in the isolated rat heart, that propofol attenuates hydrogen peroxide-induced damage and ischaemia-reperfusion injury, and that the beneficial effect of propofol is correlated with reduction of the lipid peroxidation. This study was designed to evaluate whether propofol has a cardioprotective effect against ischaemia-reperfusion injury in a rat model in vivo. ⋯ Our results suggest that propofol could be cardioprotective against ischaemia-reperfusion injury dose dependently in a rat model in vivo and that the beneficial action of propofol may be correlated with its antioxidant effect.
