To determine the accuracy of the Paratrend 7 monitor inserted into a peripheral vein in providing continuous measurements of PCO2 and pH in children with respiratory failure. ⋯ The pH and PCO2 values obtained from the Paratrend 7 monitor provide a clinically acceptable correlation with arterial values.
-
To present a case of respiratory depression following the administration of nebulised morphine. ⋯ Patients receiving inhaled morphine should be closely monitored and resuscitation equipment should be readily available.

Randomized Controlled Trial Comparative Study Clinical Trial
Haemodynamic and electroencephalograph responses to intubation during induction with propofol or propofol/fentanyl.
To observe the changes in EEG bispectral index (BIS), 95% spectral edge frequency (95% SEF) and median frequency (MF) with haemodynamic changes to intubation during induction with propofol or propofol and 2 micrograms.kg-1 fentanyl i.v. ⋯ Fentanyl, 2 micrograms.kg-1 i.v., blunted the haemodynamic responses to intubation, but failed to attenuate the arousal of cerebral cortical activity. The different haemodynamic responses postintubation but similar BIS and 95% SEF changes in the two groups suggest that BIS or 95% SEF cannot predict the haemodynamic responses to intubation during anaesthesia induction with propofol and fentanyl.
-
To describe a case of milrinone-associated tachycardia that was successfully treated with two beta-blockers. ⋯ This report demonstrates the efficacy of esmolol and metoprolol for the treatment of milrinone-associated tachycardia, without compromising the haemodynamic effects of milrinone.

We report a case of ischaemic optic neuropathy which occurred after prolonged spine surgery in the prone position in an obese, diabetic patient. ⋯ This patient developed ischaemic optic neuropathy from a prolonged interval in the prone position of the Relton-Hall frame, which may be related to venous engorgement.
