To determine the effects of sevoflurane on cerebrovascular carbon dioxide reactivity (CCO2R), middle cerebral artery blood flow velocity (CBFV) was measured at different levels of PE'CO2 by transcranial Doppler sonography in 16 ASA I or II children, aged 18 months to 7 yr undergoing elective urological surgery. ⋯ CCO2R is preserved in healthy children anaesthetized with 1.0 MAC sevoflurane.

Case Reports
Intraoperative pulmonary oedema in a child following systemic absorption of phenylephrine eyedrops.
Ophthalmic surgeons often apply phenylephrine topically to effect pupillary dilatation. We describe a paediatric patient in whom cardiac arrhythmias, severe hypertension and pulmonary oedema occurred following intraoperative ocular phenylephrine administration. We believe that systemic absorption of the drug was responsible and discuss ways in which this might be reduced when ocular phenylephrine is used in this context.

A 67-yr-old man, undergoing pulmonary metastasis resection, experienced a postoperative cardiopulmonary arrest as a result of severe bleeding. Cardiopulmonary resuscitation (CPR) was initiated, then bispectral index (BIS) monitoring was used which reassured the medical team of the adequacy of the resuscitation.
