The South African Surgical Outcomes Study : a seven-day prospective observational cohort study : preliminary results : SASA main conferenceSource: Southern African Journal of Anaesthesia and Analgesia 21, pp 72 –74 (2015)More Less
Background: Non-cardiac surgical morbidity and mortality is a major global public health burden. Data from sub-Saharan African countries on perioperative outcomes are sparse. South Africa presents a unique public health problem simultaneously engulfed by four epidemics of poverty-related diseases, noncommunicable diseases, human immunodeficiency virus and related diseases, and injury and violence. Understanding the effects of these epidemics on perioperative outcomes may provide an important perspective on both South African and surgical global health.
Objectives: The objective was to understand the associations with perioperative mortality and critical care admission in South Africa.
Method: A seven-day national, multicentre, prospective, observational cohort study was conducted in 50 government-funded hospitals in South Africa. This study is known as the South African Surgical Outcomes Study (SASOS). Participants included patients ≥ 16 years of age undergoing inpatient, non-cardiac surgery between 19 May and 26 May 2014.
Outcomes: The primary outcome was in-hospital mortality. Secondary outcomes included duration of hospital stay, admission to the critical care unit after surgery and the duration of the critical care stay. The proportional contribution of noncommunicable diseases, communicable diseases and injuries to perioperative mortality and critical care admission were calculated using population attributable risk statistics.
Results: Data on nearly 98% of all eligible patients were submitted from recruiting hospitals. Crude in-hospital mortality was 3.1%, with a postoperative admission to critical care figure of 6.5%. Over 40% of critical care admissions were unplanned. Over half the surgeries in South Africa were classified as urgent or emergent surgery. Urgent or emergent surgery has a population attributable risk for mortality of 26%, and for admission to critical care of 24%.
Conclusion: Most patients in South Africa undergo urgent and emergent surgery, which has a strong association with mortality, unplanned critical care admissions and longer critical care stay. Noncommunicable diseases have a larger proportional contribution to morbidity and mortality than infections and injuries. This study was registered on ClinicalTrials.gov (NCT02141867).
Funding: This study was funded by the South African Society of Anaesthesiologists and the Vascular Society of Southern Africa.
Case report of sudden death in a child with Williams syndrome following administration of anaesthesia : case reportSource: Southern African Journal of Anaesthesia and Analgesia 21, pp 75 –78 (2015)More Less
Williams syndrome is a neurodevelopmental disorder characterized by distinctive personality traits, facial features (so called "elfin face") and cardiac abnormalities, of which supravalvular aortic stenosis is the most common lesion found. The cause is a deletion of a group of genes on chromosome 7q11.23. Administration of anaesthesia to these patients carries a higher risk for sudden death due to the cardiac defects. The purpose of this case study is to demonstrate the entity in the South African population, to review the literature, to put emphasis on the multi-disciplinary approach in the pre-operative management, and to review the medico-legal investigation of intra-operative deaths. Furthermore, administration of anaesthesia in the remote location and to syndromic children will also be discussed.
