Postoperative nausea and vomiting at Landspitali: A prospective study.
In the last decade, anaesthesia practice has changed at Landspitali, where the majority of patients now receive antiemetic prophylaxis, and the use of total intravenous anaesthesia is the dominant mode for maintenance of anaesthesia. The aim of this study was to assess the incidence of postoperative nausea and vomiting (PONV) in a prospective way, the use of PONV prophylaxis, and clinical risk factors associated with PONV during this era. ⋯ The incidence of PONV is generally low in this diverse surgical population where anaesthesia is mostly maintained with total intravenous anaesthesia and PONV prophylaxis is common. PONV remains a predictable complication following anaesthesia, suggesting further improvement in its prevention is possible.

Long-term cognitive and pulmonary functions following a lower versus a higher oxygenation target in the HOT-ICU and HOT-COVID trials: A protocol update.
The Handling Oxygenation Targets in the Intensive Care Unit (HOT-ICU) trial was a multicentre, randomised, parallel-group trial of a lower oxygenation target (arterial partial pressure of oxygen [PaO2 ] = 8 kPa) versus a higher oxygenation target (PaO2 = 12 kPa) in adult ICU patients with acute hypoxaemic respiratory failure; the Handling Oxygenation Targets in coronavirus disease 2019 (HOT-COVID) tested the same oxygenation targets in patients with confirmed COVID-19. In this study, we aim to evaluate the long-term effects of these oxygenation targets on cognitive and pulmonary function. We hypothesise that a lower oxygenation target throughout the ICU stay may result in cognitive impairment, whereas a higher oxygenation target may result in impaired pulmonary function. ⋯ This study will provide important information on the long-term effects of a lower versus a higher oxygenation target on long-term cognitive and pulmonary functions in adult ICU patients with acute hypoxaemic respiratory failure.

Difficult intubation in syndromic versus nonsyndromic forms of micrognathia in children.
We investigated how syndromic versus nonsyndromic forms of micrognathia impacted difficult intubation outcomes in children. Primary outcome was the first-attempt success rate of tracheal intubation, secondary outcomes were number of intubation attempts and complications. We hypothesized that syndromic micrognathia would be associated with lower first-attempt success rate. ⋯ Presence of syndrome was not associated with lower first-attempt success rate on intubation, number of intubation attempts, or complication rate among micrognathic patients difficult to intubate, despite more associated craniofacial abnormalities. Nonsyndromic patients were more likely to have unanticipated difficult intubations, first attempt with direct laryngoscopy.

Risk prediction models in emergency surgery: Protocol for a scoping review.
Risk prediction models are used for many purposes in emergency surgery, including critical care triage and benchmarking. Several risk prediction models have been developed, and some are used for purposes other than those for which they were developed. We aim to provide an overview of the existing literature on risk prediction models used in emergency surgery and highlight knowledge gaps. ⋯ The outlined scoping review will summarize the existing literature on risk prediction models used in emergency surgery and highlight knowledge gaps.

The effects of troponin screening among patients undergoing acute high-risk abdominal surgery: A retrospective cohort study.
Acute high-risk abdominal (AHA) surgery is associated with a high short-term mortality rate. This might be partly attributed to myocardial injury after non-cardiac surgery (MINS) defined by elevated postoperative troponin levels. The myocardial injury is often asymptomatic; thus, troponin screening seems to be the best diagnostic method. We aimed to assess whether implementing troponin screening with subsequent individualised interventions as standard care is associated with reduced mortality after AHA surgery. We also explored the treatment implications in the screening period. ⋯ The implementation of postoperative troponin screening was not associated with reduced mortality after AHA surgery. Research on the prevention and treatment of MINS is warranted before the implementation of standard troponin screening.
