Paradoxical changes in bispectral index during nitrous oxide administration.

نویسنده

چکیده

I report two patients undergoing open heart surgery, with nitrous oxide and isoflurane anaesthesia, for whom bispectral index (BIS) monitoring showed high BIS values with nitrous oxide and isoflurane anaesthesia. The BIS decreased immediately after nitrous oxide was stopped and increased again after nitrous oxide was restarted.

Increasing isoflurane concentration may cause paradoxical increases in the EEG bispectral index in surgical patients.

We have studied the effects of increases in isoflurane concentration on the EEG bispectral index (BIS) in 70 patients anaesthetized with isoflurane-nitrous oxide-sufentanil for major abdominal surgery. During surgery, baseline BIS was recorded at 0.8% end-tidal isoflurane with nitrous oxide in oxygen (FIO2 0.35). After this, end-tidal isoflurane was increased to 1.6% for 15 min and decreased su...

Nitrous oxide does not alter bispectral index: study with nitrous oxide as sole agent and as an adjunct to i.v. anaesthesia.

We have studied the effect of nitrous oxide on bispectral index (BIS), calculated from a bipolar encephalogram. Inhalation of 70% nitrous oxide resulted in loss of consciousness in all healthy volunteers (n = 10) but no change in BIS. Brief inhalation up to 1.2% sevoflurane also resulted in loss of consciousness in volunteers (n = 5), but with sevoflurane, BIS decreased. BIS and the haemodynami...

Nitrous Oxide Sedation and Bispectral Index

OBJECTIVES To determine whether bispectral analysis (BIS) changes during nitrous oxide (N(2)O) sedation in anxious children undergoing extraction of primary teeth. METHODS In this prospective study 45, ASA physical status I children, aged between 7 to 12 years and scheduled for primary teeth extraction under N(2)O/O(2) sedation are included. At baseline (T0) and during the sedation procedure ...
