South Africa (SA) has experienced multiple waves of this pandemic, spanning the pre-vaccine and vaccine periods. The method and initiation of treatment is a debated topic, changing according to evolving research and the literature. The present study investigated the use of high-dose intravenous immunoglobulin (IVIg) as a salvage therapy after initial medical treatment failure.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Objectives: &lt;/strong&gt;To compare disease progression among critically ill COVID-19 pneumonia patients receiving IVIg therapy with that in patients receiving standard of care (SoC), in respect of inflammation, organ dysfunction and oxygenation.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;This was a single-centre, retrospective study of patients admitted to the intensive care unit (ICU) at Chris Hani Baragwanath Academic Hospital, Johannesburg, SA, during the pre-vaccine COVID-19 pandemic. Demographics, inflammatory markers (C-reactive protein (CRP)), organ function (Sequential Organ Failure Assessment (SOFA) score), oxygenation (ratio of partial pressure of oxygen in arterial blood to fraction of inspiratory oxygen (P/F ratio)), overall mortality and complications (nosocomial infections and thromboembolism) were recorded and compared.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;We included 113 eligible patients in the study. The IVIg cohort had a significantly lower initial P/F ratio than the SoC cohort (p=0.01), but the change in P/F ratio was similar (p=0.54). Initial CRP and changes in CRP were similar in the two groups (p=0.38 and p=0.75, respectively), as were initial SOFA score and changes in SOFA score (p=0.18 and p=0.08, respectively) and vasopressor dose on day 0 and day 5 (p=0.97 and p=0.93, respectively). Duration of mechanical ventilation did not differ significantly between the IVIg group and the SoC group (p=0.13). There were no significant differences in measured complications between the two groups. On univariate analysis, the relative risk of death was 1.6 times higher (95% confidence interval (CI) 1.1 - 2.3) in the IVIg group; however, a logistical regression model demonstrated that only a higher P/F ratio (odds ratio (OR) 0.991; 95% CI 0.983 - 0.997) and higher mean airway pressure (OR 1.283; 95% CI 1.026 - 1.604) were significantly associated with ICU mortality.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;Use of IVIg in our study was directed at an older population, with significantly worse oxygenation.

However, critical care nurses who prioritise caring can meaningfully connect with critically ill patient and their families, resulting in positive healthcare outcomes.</p><p><strong>Objectives: </strong>To assess critical care nurses' orientations to caring for critically ill patient and their families.</p><p><strong>Methods: </strong>A quantitative, descriptive, cross-sectional study was conducted with 139 purposively sampled critical care nurses working in a tertiary referral hospital in KwaZulu-Natal, South Africa. Data were collected using the Caring Assessment for Caregivers questionnaire, and analysis included descriptive and comparative statistics.</p><p><strong>Results: </strong>The overall mean score of critical care nurses' orientations to caring was 116.01 (range of 25 - 125). Of the five subscales (dimensions), the dimension of '<i>Maintaining belief</i>' had the highest mean score of 24.25 and the dimension of '<i>Being with</i>' had the lowest mean score of 22.70 (range 5 - 25).</p><p><strong>Conclusion: </strong>While critical care nurses reported high overall orientations to caring, lower mean scores on the subscale '<i>Being with</i>' suggest that there are areas for critical care nurses to grow in their role as carers. Further research using qualitative approaches may shed valuable insights into how the critical care environment impacts the caring orientations of critical care nurses.</p><p><strong>Contribution of the study: </strong>The study aims to highlight the orientations of critical care nurses to different areas of caring. In so doing management can provide specific support to nurses to strengthen their caring abilities.</p>","PeriodicalId":75194,"journal":{"name":"The Southern African journal of critical care : the official journal of the Critical Care Society","volume":"40 2","pages":"e1905"},"PeriodicalIF":0.0,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11669151/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142900916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
