The Australian Incident Monitoring Study. Air embolism--an analysis of 2000 incident reports.
There were 19 cases of air embolism (1%) among the first 2000 incidents reported to the Australian Incident Monitoring Study. No embolism-induced fatalities were reported. Serious acute systemic effects occurred in 14 incidents; one circulatory arrest required electrical counter-shock. ⋯ Doppler monitoring was not reported in this series. A successful first response for management included head-down posture, manual ventilation, 100% oxygen and control of the air entry site. Cerebral arterial gas embolism may induce vascular endothelial damage and possible delayed neurological sequelae; hyperbaric oxygen therapy should be considered.

The Australian Incident Monitoring Study. Recovery room incidents in the first 2000 incident reports.
Of the first 2000 incidents reported to the Australian Incident Monitoring Study 120 (6%) occurred in the recovery room after general, regional or local anaesthesia. Over two thirds (69%) of these involved the respiratory system, 19% were cardiovascular, 3% involved the central nervous system and 9% were miscellaneous in nature. These recovery room incidents were associated with significantly more adverse outcomes (56%) than incidents in the operating theatre (24%). ⋯ Over three quarters (77%) of all recovery incidents (and 88% of respiratory incidents) were detected clinically; the remainder were first detected by a monitor. A theoretical analysis showed that over 95% of respiratory events, had they been allowed to evolve, would have been detected by pulse oximetry before organ damage occurred, emphasising the potential importance of pulse oximetry in reducing adverse outcome from any complication in the recovery ward which might be "missed" by clinical observation. The findings of this study underline the importance of having an adequate number of trained recovery nursing staff supported by the availability of a pulse oximeter for each patient at least until the return of protective reflexes and the ability to maintain adequate arterial saturation has been established.
