Does significant hypoxia occur during electroconvulsive therapy?
Does significant hypoxia occur during electroconvulsive therapy?
Significant hypoxia can occur during electroconvulsive therapy, highlighting the critical need for adequate oxygenation and ventilation prior to administering the shock.
Hypoxia during ECT was associated with pre-shock ventilation; leaves open optimal protocols for prospective trials.
Oxygen saturation was measured during anaesthesia and electroconvulsive therapy (ECT) using ear oximetry. Significant hypoxia occurred during some treatments; desaturation related to the number of ventilations performed after muscle relaxation and prior to the shock. Desaturation did not correlate significantly with seizure duration. These findings highlight the need for adequate oxygenation during ECT.
