Targeted temperature management in patients with intracerebral haemorrhage, subarachnoid haemorrhage, or acute ischaemic stroke: updated consensus guideline recommendations by the Neuroprotective Therapy Consensus Review (NTCR) group.

BACKGROUND: There is a lack of consistent, evidence-based guidelines for the management of patients with fever after brain injury. The aim was to update previously published consensus recommendations on targeted temperature management after intracerebral haemorrhage, aneurysmal subarachnoid haemorrhage, and acute ischaemic stroke in patients who require admission to critical care. METHODS: A modified Delphi consensus, the Neuroprotective Therapy Consensus Review (NTCR), included 19 international neuro-intensive care experts with a subspecialty interest in the acute management of intracerebral haemorrhage, aneurysmal subarachnoid haemorrhage, and acute ischaemic stroke. An online, anonymised survey was completed ahead of the meeting before the group came together to consolidate consensus and finalise recommendations on targeted temperature management. A threshold of ≥80% for consensus was set for all statements. RESULTS: Recommendations were formulated based on existing evidence, literature review, and consensus. After intracerebral haemorrhage, aneurysmal subarachnoid haemorrhage, and acute ischaemic stroke in patients who require critical care admission, core temperature should ideally be monitored continuously and maintained between 36.0°C and 37.5°C using automated feedback-controlled devices, where possible. Targeted temperature management should be commenced within 1 h of first fever identification with appropriate diagnosis and treatment of infection, maintained for as long as the brain remains at risk of secondary injury, and rewarming should be controlled. Shivering should be monitored and managed to limit risk of secondary injury. Following a single protocol for targeted temperature management across intracerebral haemorrhage, aneurysmal subarachnoid haemorrhage, and acute ischaemic stroke is desirable. CONCLUSIONS: Based on a modified Delphi expert consensus process, these guidelines aim to improve the quality of targeted temperature management for patients after intracerebral haemorrhage, aneurysmal subarachnoid haemorrhage, and acute ischaemic stroke in critical care, highlighting the need for further research to improve clinical guidelines in this setting.

Understanding the Intensive Care Unit Experience of Patients and Relatives at the End-of-Life During the Coronavirus Disease 2019 Pandemic.

The coronavirus disease 2019 (COVID-19) pandemic has had a significant impact on patients and relatives' experiences of end-of-life care, as well as changing the provision of these services in intensive care units (ICUs) across the world. Established methods for assisting relatives through the grieving process have required modification due to the unique features and circumstances surrounding deaths from this disease. This mixed-methods study from the United Kingdom (UK) aims to review data from patients who died in a large ICU (the unit had a capacity for more than 100 ventilated patients), over the course of approximately 1 year. The inpatient noting of these patients was reviewed specifically for details of visiting practices, chaplaincy support, and patient positioning (prone vs supine) prior to death. Using this data, recommendations are made to improve end-of-life care services. To allow relatives the opportunity to attend the ICU, there is a need for early recognition of patients approaching the end of life. Clear explanations of the need for prone positioning and increased access to chaplaincy services were also identified.

Temperature management of adult burn patients in intensive care: findings from a retrospective cohort study in a tertiary centre in the United Kingdom.

INTRODUCTION: Patients with major burn injury are prone to hypothermia, potentially resulting in an increase in mortality and length of hospital stay. Our study comprehensively evaluates the practicalities of physiological thermoregulation and temperature control in the largest cohort of critically ill adult burn patients to date. MATERIAL AND METHODS: This retrospective study of routinely collected patient data from the Intensive Care Unit (ICU) of the West Midlands Burn Centre was conducted over a three-year period (2016-2019). Data were analysed to assess temperature control against local and International Society for Burn Injury (ISBI) standards. RESULTS: Thirty-one patients with significant burn injuries, requiring active critical care treatment for more than 48 hours were included (total body surface area [TBSA] mean = 42.7%, SD = 18.1%; revised Baux score [rBaux] = 99, SD = 25). The majority were male (77.29%) with an average age of 44 years (17-77 years). The patients were cared for in the ICU for a total of 15 119 hours. Hypothermia, defined as core temperature below 36.0°C, was recorded for 251 hours (2% of total stay). Only 27 patients (87%) had their temperature ≥ 36°C for more than 95% of their admission. Non-survivors were more prone to hypothermia during their stay in ICU. There was an association between rBaux score and post-opera-tive temperature, with a 0.12°C decrease per 10 points increase in rBaux score (P = 0.04). CONCLUSIONS: We have observed a high variability of temperature control between individual patients, especially in non-survivors, and have demonstrated an association between high rBaux score and poor temperature control, specifically during the postoperative period.

A descriptive survey of operating theatre and intensive care unit temperature management of burn patients in the United Kingdom.

BACKGROUND: Patients with major burns lose the normal thermoregulatory function of their skin. They exhibit profound changes in metabolism which aim to compensate for the heat loss associated with water loss through burnt skin. Although these changes in physiology are well documented, the optimal methods for temperature management in both the Operating Theatre and Intensive Care Unit are less clear. METHODS: We distributed a survey consisting of 19 questions to all burn units and centres in the United Kingdom with the aim of ascertaining perception of both hypo and hyperthermia, as well as methods used to manage both of these scenarios. RESULTS: In the Operating Theatre, most respondents stated that they measured core temperature (82%); either alone (33%) or in conjunction with peripheral temperature (49%). In the Intensive Care Unit, most respondents measured both core and peripheral temperature (67%), with only a small minority not measuring core temperature (13%). Taking into consideration all professional groups, patients were considered hypothermic if their body temperature was less than 36.2°C (+/-0.7°C). On average, a patient was considered hyperthermic if their body temperature was above 38.8°C (+/-0.6°C). CONCLUSION: Differences in perception between the professional groups surveyed did not reach clinical or statistical significance. In both the Operating Theatre and Intensive Care Unit, hypothermia was most often managed by increasing the ambient room temperature whereas hyperthermia was most often managed by giving paracetamol. As far as we are aware, this is the first study of the management of altered thermoregulation in major burn patients in the United Kingdom.

A comment on prognostic factors in burns.

We read the recent paper "Prognostic factors in patients with burns" [1] by Zielinski et al. with great interest. The article is very informative, in a concise and eloquent manner, allowing the reader to familiarise themselves with the plethora of prognostication models used worldwide in the assessment of burn patients. However, reading the paper we noticed that two aspects may require further consideration to provide the reader with a more comprehensive understanding of prognostication in burn patients.

Initial management of acute ischaemic stroke.

The management of acute ischaemic stroke has been revolutionised by effective reperfusion therapies including thrombolysis and mechanical thrombectomy. In particular, mechanical thrombectomy has heralded a new era in stroke medicine. There have also been developments to improve clinical outcomes for patients who have had an acute ischaemic stroke but are not eligible for this procedure. This article presents an update on the initial management of acute ischaemic stroke, including reperfusion therapies, periprocedural considerations and ongoing research for potential improvements in the care of these patients.

Critical care management of the patient with an acute ischaemic stroke.

Acute ischaemic stroke is a leading cause of morbidity and mortality worldwide. In the UK alone, there are more than 100 000 strokes per year, causing 38 000 deaths. While the incidence remains high, there has been significant medical progress in reducing mortality following a stroke. Admission of patients to specialised stroke units has led to an improvement in clinical outcomes, but the role of intensive care is less well defined. This article reviews the current critical care management and neuro-therapeutic options after an acute ischaemic stroke.

Trainee doctors' experiences of learning and well-being while working in intensive care during the COVID-19 pandemic: a qualitative study using appreciative inquiry.

OBJECTIVES: Concern about trainee work-related well-being has been raised in recent years and is the subject of several reviews, reports and research studies. This study aimed to understand the experiences of trainees working in a large intensive care unit during the first surge of the COVID-19 pandemic from an educational and operational perspective in order to highlight what worked and what could be improved. DESIGN: A qualitative study using peer-to-peer semistructured interviews, developed using appreciative inquiry methodology, was conducted during July 2020. Responses were analysed using a thematic analysis technique. SETTING: A large, tertiary intensive care unit in the UK. PARTICIPANTS: All trainees in anaesthesia and intensive care working on the intensive care unit during the first surge were invited to participate. RESULTS: Forty interviews were conducted and four over-arching themes were identified. These were: feeling safe and supported; physical demands; the emotional burden of caring; and a sense of fulfilment, value and personal development. Positive aspects of the organisational response to the pandemic included communication, personal protective equipment supply, team working and well-being support. Suggestions for improvement focused on rest facilities, rota patterns and hierarchies, creating opportunities for reflection and ensuring continued educational and training opportunities despite operational demands. CONCLUSIONS: Trainees described opportunities for learning and fulfilment, as well as challenges, in working through a pandemic. Trainees described their needs and how well these were met during the pandemic. Ideas for improvement most frequently related to basic needs including safety and fatigue, but suggestions also related to supporting learning and development. The appreciative inquiry methodology of the project facilitated effective reflection on positive aspects of trainee experiences.
