Simultaneous, Dual Continuous Venovenous Haemodiafiltration as Salvage Therapy for Severe Sodium Valproate Intoxication.

Sodium valproate overdose leads to CNS depression, cerebral oedema, and severe metabolic acidosis in cases of severe toxicity. Extracorporeal removal, specifically through intermittent haemodialysis, is recommended, though not always tolerated by or accessible to haemodynamically unstable patients in intensive care units. We present a case of a male in his mid-twenties presenting following a massive, intentional overdose of 13 g of sodium valproate over 7 hours, with an initial valproate blood concentration of 975 µg/ml (normal 50-100 µg/ml). He was hypoxic and severely acidotic on arrival and was given fluids and L-carnitine according to TOXBASE guidelines. This resulted in only marginal improvement to his acidosis. Once transferred to our intensive care unit, the patient was started on inotropic support followed by continuous venovenous hemofiltration (CVVHDF) at the maximum effluent rate of 60 ml/kg/hr. Due to his persisting metabolic acidosis and worsening hyperlacataemia, dual CVVHDF was started by adding another filter in series after 26 hours, increasing the maximum effluent rate to 96 ml/kg/hr. The patient remained on dual CVVHDF for 31 hours, during which his acidosis and lactate showed considerable improvement, and he was subsequently stepped down to single-filter CVVHDF for a further 20 hours until complete resolution of his acidosis. This case report recognises dual CVVHDF as a viable salvage therapy for severe sodium valproate overdose by facilitating the achievement of a higher effluent flow rate compared to what can be accomplished with single-filter CVVHDF.

GP perceptions of informal peer support in primary care: a qualitative study.

BACKGROUND: Burnout is on the rise among GPs in the UK. One approach to mitigating burnout in GPs is through informal peer support (IPS). This refers to GPs informally supporting each other on an informational (advice) and emotional (venting and reflection) basis. AIM: To explore GPs' perceptions of how IPS manifests in the primary care setting and what factors influence effective GP engagement with IPS. DESIGN & SETTING: A qualitative study utilising semi-structured interviews to develop an in-depth understanding of GPs' perceptions of IPS, based on their experiences in practices across England. METHOD: Fifteen GPs were purposively sampled to include the views of locum, salaried, and trainee GPs and GP partners. Semi-structured interviews were conducted, recorded, and transcribed verbatim. Transcripts were analysed using inductive thematic analysis. RESULTS: Four types of IPS were identified relating to emotional support, professional advice, sharing of workload, and mentorship, which reflect existing literature. The frequency and efficacy of IPS was found to be influenced by several factors categorised into individual traits, practice culture, and occupation. CONCLUSION: The results highlight where efforts should be directed to improve GP engagement with IPS. Specifically, GP leaders have an important role in shaping practice culture and fostering an environment for IPS to occur. Practices may also benefit from introducing professional development measures targeted at training GPs to better support each other based on their individual traits.

Cost-effectiveness analysis of antibiotic prophylaxis versus no antibiotic prophylaxis for acute cholecystectomy.

OBJECTIVE: For acute cholecystitis, the treatment of choice is laparoscopic cholecystectomy. In mild-to-moderate cases, the use of antibiotic prophylaxis for the prevention of postoperative infectious complications (POICs) lacks evidence regarding its cost-effectiveness when compared with no prophylaxis. In the context of rising antimicrobial resistance, there is a clear rationale for a cost-effectiveness analysis (CEA) to determine the most efficient use of National Health Service resources and antibiotic routine usage. DESIGN: 16 of 226 patients (7.1%) in the single-dose prophylaxis group and 29 of 231 (12.6%) in the non-prophylaxis group developed POICs. A CEA was carried out using health outcome data from thePerioperative antibiotic prophylaxis in the treatment of acute cholecystitis (PEANUTS II) multicentre, randomised, open-label, non-inferiority, clinical trial. Costs were measured in monetary units using pound sterling, and effectiveness expressed as POICs avoided within the first 30 days after cholecystectomy. RESULTS: This CEA produced an incremental cost-effectiveness ratio of -£792.70. This suggests a modest cost-effectiveness of antibiotic prophylaxis being marginally less costly and more effective than no prophylaxis. Three sensitivity analyses were executed considering full adherence to the antibiotic, POICs with increased complexity and break-point analysis suggesting caution in the recommendation of systematic use of antibiotic prophylaxis for the prevention of POICs. CONCLUSION: The results of this CEA point to greater consensus in UK-based guidelines surrounding the provision of antibiotic prophylaxis for mild-to-moderate cases of acute cholecystitis.
