ABSTRACT

BACKGROUND: This study analysed whether local anaesthetic wound catheter infiltration (LA-WCI) as an adjunct to intravenous patient-controlled analgesia (IV-PCA) provides superior outcomes compared to IV-PCA alone following liver resection. METHODS: A systematic review and meta-analysis was conducted for randomised control trials (RCTs) comparing LA-WCI with IV-PCA(LA-WCI group) versus IV-PCA alone (IV-PCA group). PubMed and the Cochrane Library were searched for relevant articles. RESULTS: Six RCTs with a total of 440 patients were included. Opioid use in the initial 48 h was less in the LA-WCI group [MD -21.27 mg (-39.39,-3.15), p = 0.02]. Pain scores were lower in the LA-WCI group at rest at POD0 (post-operative day 0)6-8 h (p = 0.0009), POD1AM(p = 0.01), POD1PM(p = 0.02) and POD2 (p = 0.0006), and exertion at POD0 0-2 h (p = 0.05), POD1AM(p = 0.03), POD1PM(p = 0.03), POD2 (p = 0.03) and POD3 (p = 0.01). LA-WCI group had reduced length of hospital stay [MD -1.32 days (-2.23,-0.40),p = 0.005], time to ambulation [MD -5.94 h (-8.47,-3.42),p = 0.00001] and incidence of nausea and vomiting (PONV) [OR 0.17 (0.07,0.43),p = 0.0002]. No differences were observed in length of intensive care unit (ICU) stay or incidence of surgical site infections. DISCUSSION: LA-WCI as an adjunct to opiate IV-PCA post-hepatectomy reduces opioid use, pain scores at multiple time points at rest and exertion, length of hospital stay, time to ambulation and PONV. However, LA-WCI use does not alter length of ICU stay or incidence of wound infection.

ABSTRACT

A number of studies have highlighted physiological data from the first surge in critically unwell Covid-19 patients but there is a paucity of data describing emerging variants of SARS-CoV-2, such as B.1.1.7. We compared ventilatory parameters, biochemical and physiological data and mortality between the first and second COVID-19 surges in the United Kingdom, where distinct variants of SARS-CoV-2 were the dominant stain. We performed a retrospective cohort study investigating critically unwell patients admitted with COVID-19 across three tertiary regional ICUs in London, UK. Of 1782 adult ICU patients screened, 330 intubated and ventilated patients diagnosed with COVID-19 were included. In the second wave where B.1.1.7 variant was the dominant strain, patients were had increased severity of ARDS whilst compliance was greater (p<0.05) and d-dimer lower. The 28-day mortality was not statistically significant (1st wave: 42.2% vs 2nd wave: 39.8%). However, when adjusted for key covariates, the hazard ratio for 28-day mortality in those patients with B.1.1.7 was 3.79 (CI 1.04-13.8; p = 0.043) compared to the original strain. During the second surge in the UK, where the COVID-19 variant B.1.1.7 was most prevalent, significantly more patients presented to critical care with severe ARDS. Furthermore, mortality risk was significantly greater in our ICU population during the second wave of the pandemic in those patients with B.1.1.7. As ICUs are experiencing further waves (particularly by the delta (B.1.617.2) variant), we highlight the urgent need for prospective studies describing immunological and pathophysiological differences across novel emerging variants.

ABSTRACT

The right to liberty and security of the person is protected by Article 5 of the European Convention on Human Rights which has been incorporated into the Human Rights Act 1998. The 2014 Supreme Court judgment in the case commonly known as Cheshire West provided for an 'acid test' to be employed in establishing a deprivation of liberty. This 'acid test' of 'continuous supervision and not free to leave' led to concerns that patients lacking capacity being treated on an Intensive Care Unit could be at risk of a 'deprivation of liberty', if this authority was applicable to this setting. This article revisits the aftermath of Cheshire West before describing the recent legal developments around deprivation of liberty pertaining to intensive care by summarising the recent Ferreira judgments which appear for now to answer the question as to the applicability of Cheshire West in life-saving treatment.

ABSTRACT

The aim of this study was to identify key cytokine polymorphisms associated with disease susceptibility, clinical phenotype, and outcome in patients with chronic anterior uveitis (CAU) as compared to those with recurrent self-limiting anterior uveitis (RAU). One hundred fifty seven British Caucasian patients with anterior uveitis were identified and divided into those where the inflammatory process lasted less than 3 months (RAU=118) and those where the inflammation persisted longer than 3 months (CAU=39). Patients with CAU were further sub-divided into idiopathic CAU, CAU associated with systemic disease, CAU with and without complications (posterior synechiae, posterior subcapsular lens opacity, raised intraocular pressure, cystoid macular oedema, and poor response to treatment). Sixty-six healthy controls were ethnically matched. TaqMan PCR amplification was used to genotype five single nucleotide polymorphisms in cytokine genes; IL-1RN+2018, IL-6-174, IL-10-1082, TNF-238, TNF-308 and these were correlated with clinical phenotype.
