Severely ill patients with COVID-19 are challenging to sedate and often require high-dose sedation and analgesic regimens. Ketamine can be an effective adjunct to facilitate sedation of critically ill patients but its effects on sedation level and inflammation in COVID-19 patients have not been studied. This retrospective, observational cohort study evaluated the effect of ketamine infusions on inflammatory biomarkers and clinical outcomes in mechanically ventilated patients with SARS-CoV-2 infection. A total of 186 patients were identified (47 received ketamine, 139 did not). Patients who received ketamine were significantly younger than those who did not (mean (standard deviation) 59.2 (14.2) years versus 66.3 (14.4) years; P = 0.004), but there was no statistically significant difference in body mass index (P = 0.25) or sex distribution (P = 0.91) between groups. Mechanically ventilated patients who received ketamine infusions had a statistically significant reduction in Richmond Agitation-Sedation Scale score (-3.0 versus -2.0, P < 0.001). Regarding inflammatory biomarkers, ketamine was associated with a reduction in ferritin (P = 0.02) and lactate (P = 0.01), but no such association was observed for C-reactive protein (P = 0.27), lactate dehydrogenase (P = 0.64) or interleukin-6 (P = 0.87). No significant association was observed between ketamine administration and mortality (odds ratio 0.971; 95% confidence interval 0.501 to 1.882; P = 0.93). Ketamine infusion was associated with improved sedation depth in mechanically ventilated COVID-19 patients and provided a modest anti-inflammatory benefit but did not confer benefit with respect to mortality or intensive care unit length of stay.

Nitrous oxide is a potent greenhouse gas and ozone-depleting agent with a long atmospheric lifetime. Several previous reports indicate that over half of supplied nitrous oxide is wasted from leaking manifold-pipeline systems infrastructure prior to patient use, and that remediating leaks can have significant environmental benefits. We describe an accurate, simple and cost-effective cylinder weighing method to quantify nitrous oxide leak from the manifold-pipeline network at our tertiary non-obstetric facility. Nitrous oxide cylinder depletion was prospectively compared with clinical usage derived from the electronic medical record over an 18-day period. A total of 1932 l (3.62 kg) of nitrous oxide was used in 35 operating theatre cases during the period. This was only 16.5% of actual cylinder depletion (11,686 l; 21.88 kg), indicating that 83.5% (9754 l; 18.26 kg) of nitrous oxide had leaked to the atmosphere (376 ml/minute; 22.6 l/hour; 542 l/day). The fraction of nitrous oxide wasted was consistent with a retrospective analysis of the previous 2-year period at the site that compared purchasing records with estimated clinical use. If maintained over a year, the leak would be equivalent to 101 tonnes of carbon dioxide per annum.
一氧化二氮是一种强效的温室气体和臭氧消耗剂,具有很长的大气寿命。先前的几份报告表明,在患者使用之前,超过一半的供应氧化亚氮被浪费在泄漏的歧管管道系统基础设施中,并且修复泄漏可以带来显着的环境效益。我们描述了一种准确,简单和具有成本效益的钢瓶称重方法,以量化一氧化二氮泄漏从我们的三级非产科设施的歧管管网。在18天的时间内,前瞻性地比较了一氧化二氮气瓶耗竭与来自电子病历的临床使用情况。在此期间,共在35个手术室病例中使用了1932 l (3.62 kg)氧化亚氮。这仅仅是实际汽缸损耗的16.5% (11,686 l;21.88 kg),表示83.5% (9754 l;18.26千克的一氧化二氮泄漏到大气中(每分钟376毫升;22.6升/小时;542升/天)。一氧化二氮浪费的比例与该地点前2年期间的回顾性分析一致,该分析将采购记录与估计的临床使用进行了比较。如果维持一年以上,泄漏量将相当于每年101吨二氧化碳。

Post-mastectomy pain syndrome (PMPS) is a type of chronic postsurgical pain that can be severe, debilitating and frequently encountered in clinical practice. Multiple studies have focused on prevention, identifying risk factors and treating this condition. Nonetheless, PMPS remains a complex condition to treat effectively. In this case report, we describe the use of percutaneous electrical nerve stimulation in a breast cancer patient who experienced PMPS refractory to conventional treatments.

Two recent cases of central retinal artery occlusion under otherwise uncomplicated sub-Tenon's block that resulted in significant visual loss after cataract surgery prompted us to undertake a literature review of such cases. We identified 97 cases of retinal artery occlusion after ophthalmic surgery under regional anaesthesia that had no immediate signs of block-related complications. These occurred after various intraocular (87%) and extraocular (13%) operations, across a wide range of ages (19-89 years) on patients with (59%) or without (39%) known risk factors. The anaesthetic techniques included 40 retrobulbar blocks, 36 peribulbar blocks, 19 sub-Tenon's blocks, one topical anaesthetic and one unspecified local anaesthetic. Different strengths of lidocaine, bupivacaine, mepivacaine and ropivacaine, either alone or in various combinations, were used. The details of the anaesthetic techniques were often incomplete in the reports, which made comparison and analysis difficult. Only nine cases had their cause (optic nerve sheath injury) identified, while the mechanism of injury was unclear in the remaining patients. Various mechanisms were postulated; however, the cause was likely to be multifactorial due to patient, surgical and anaesthetic risk factors, especially in those with compromised retinal circulation. As there were no definite risk factors identified, no specific recommendations could be made to avoid this devastating outcome. We have provided rationales for some general considerations, which may reduce this risk, and propose anaesthetic options for ophthalmic surgery on the fellow eye if required, based both on our literature review and our personal experience.

A survey sent to fellows of the Australian and New Zealand College of Anaesthetists (ANZCA) aimed to document issues affecting gender equity in the anaesthesia workplace. A response rate of 38% was achieved, with women representing a greater proportion of respondents (64.2%). On average women worked fewer hours than men and spent a larger percentage of time in public practice; however, satisfaction rates were similar between genders. There was a gender pay gap which could not be explained by the number of hours worked or years since achieving fellowship. The rates of bullying and harassment were high among all genders and have not changed in 20 years since the first gender equity survey by Strange Khursandi in 1998. Women perceived that they were more likely to be discriminated against particularly in the presence of other sources of discrimination, and highlighted the importance of the need for diversity and inclusion in anaesthetic workplaces. Furthermore, women reported higher rates of caregiving and unpaid domestic responsibilities, confirming that anaesthetists are not immune to the factors affecting broader society despite our professional status. The overall effect was summarised by half of female respondents reporting that they felt their gender was a barrier to a career in anaesthesia. While unable to be included in statistics due to low numbers, non-binary gendered anaesthetists responded and must be included in all future work. The inequities documented here are evidence that ANZCA's gender equity subcommittee must continue promoting and implementing policies in workplaces across Australia and New Zealand.

A 19-year-old woman with known maple syrup urine disease presented to hospital with metabolic crisis in the setting of influenza type A infection and intractable vomiting, rapidly progressing to acute cerebral oedema manifesting as refractory seizures and decreased level of consciousness needing emergency intubation and mechanical ventilation, continuous veno-venous haemodiafiltration and thiopentone coma. A computed tomography scan and magnetic resonance imaging of the brain demonstrated classic signs of cerebral oedema secondary to a metabolic crisis from the metabolic disorder. Her management posed multiple challenges to all teams involved due to lack of familiarity and experience in managing this clinical scenario in the adult intensive care setting.

Patients with severe clinical manifestations of coronavirus disease 2019 (COVID-19) present particular diagnostic and management challenges to critical care physicians, including identifying and responding to concurrent bacterial and fungal coinfections. This study evaluates risk factors for in-hospital mortality in patients admitted to the intensive care unit with severe COVID-19 during circulation of the B.1.617.2 (Delta) variant, including the impact of immunomodulators and bacterial and/or fungal coinfection. This retrospective cohort study enrolled patients with severe COVID-19. A Cox proportional hazard ratio analysis identified risk factors for in-hospital mortality. Outcomes were also compared between patients receiving and not receiving immunomodulatory therapy alongside standard care. Ninety patients admitted to the intensive care unit were enrolled. On multivariate analysis, the greatest risk factors for in-hospital mortality were invasive mechanical ventilation (hazard ratio (HR) = 15.27; 95% confidence interval (CI) 3.29-71.0; P < 0.001), elevated body mass index (HR = 1.07 per unit; 95% CI 1.02-1.13; P = 0.007) and older age (HR = 1.53 per decade; 95% CI 1.05-2.24; P = 0.028). Bacterial and/or fungal coinfection occurred at equal frequency in patients receiving and not receiving immunomodulatory therapy. However, in patients receiving immunomodulators, coinfection carried a significantly higher mortality risk (63.0%) compared with those without coinfection (15.4%; P = 0.038). Mortality from severe COVID-19 is significantly higher in older patients and those with elevated body mass index and requiring mechanical ventilation. Immunomodulatory therapy necessitates vigilance towards evolving coinfection in the intensive care setting.
