Abstract
Objectives: The aim of this study was to identify clinical patterns of occurrence, management and outcomes surrounding cardiac arrest during laparoscopic surgery using the Australian Incident Monitoring Study (AIMS) database to guide possible prevention and treatment. Setting: The AIMS database includes incident reports from participating clinicians from secondary and tertiary healthcare centres across Australia and New Zealand. Participants: The AIMS database holds over 11 000 peri- and intraoperative incidents. Primary and Secondary Outcome Measures: The primary outcome was to characterize the pattern of events surrounding cardiac arrest. The secondary outcome was to identify successful management strategies in the possible prevention and treatment of cardiac arrest during laparoscopic surgery. Results: Fourteen cases of cardiac arrest during laparoscopic surgery were identified. The majority of cases occurred in 'fit and healthy' patients during elective gynaecological and general surgical procedures. Twelve cases of cardiac arrest were directly associated with pneumoperitoneum with bradycardia preceding cardiac arrest in 75% of these. Management included deflation of pneumoperitoneum, atropine administration and cardiopulmonary resuscitation with circulatory restoration in all cases. The results imply vagal mechanisms associated with peritoneal distension as the predominant contributor to bradycardia and subsequent cardiac arrest during laparoscopy. Conclusions: Bradycardia during gas insufflation is not necessarily a benign event and appears to be a critical early warning sign for possible impending and unexpected cardiac arrest. Immediate deflation of pneumoperitoneum and atropine administration are effective measures that may alleviate bradycardia and possibly avert progression to cardiac arrest.
