This review describes the aetiology of corneal abrasions and evaluates the current methods of prevention. Most abrasions are caused by lagophthalmos (failure of the eyelids to close fully) during general anaesthesia, resulting in corneal drying. General(More)
Several minutes of 100 percent O2 breathing prior to inhalation induction with 79 percent N23 results in consistently higher PaO2 values during the first 10 minutes compared with prior air breathing. The theoretic maximum concentrating action of N2O uptake upon O2 is approximately the same (60 torr) regardless of gas breathed before induction.
