Quantitative neuromuscular monitoring has the potential to reduce the risk of PORC, but many anaesthetists rely on clinical assessment of neuromuscular function alone. To investigate the occurrence of PORC in the recovery room at an academic hospital in Gauteng, South Africa. Additionally, this prospective, cross-sectional study aimed to determine the extent of intraoperative neuromuscular monitoring and to assess clinical factors that may influence the risk of PORC. Patient characteristics and clinical information, including whether neuromuscular monitoring had been conducted, were recorded. Patients were evaluated by clinical assessment and determination of a quantitative train-of-four ratio (TOFR). PORC assessment methods were compared and clinical characteristics were analysed for association with TOFR status. The incidence of PORC (TOFR <0.9) in serious yet preventable condition. Vitamin D deficiency is common in intensive care unit (ICU) patients (50 - 82%) and is associated with multi-organ dysfunction. Vitamin D deficiency alters pathways of glutamine metabolism in critical illness, but the impact of vitamin D status on glutamine levels is poorly characterised. To assess the prevalence of vitamin D deficiency and its association with organ dysfunction and glutamine levels in a South African (SA) ICU. Records of 103 adult patients admitted to the Wits Donald Gordon Medical Centre ICU, Johannesburg, SA were retrospectively reviewed. 25-hydroxyvitamin D (25(OH)D) and glutamine levels were measured on admission. The association between admission vitamin D levels and glutamine levels, illness severity scores, organ support and outcomes was examined. On ICU admission, 66% (68/103) of patients were vitamin D deficient (<20 ng/mL) (95% confidence interv
