Parental access to hospitalised children during infectious disease pandemics such as COVID-19.

The COVID-19 pandemic has resulted in many hospitals severely limiting or denying parents access to their hospitalised children. This article provides guidance for hospital managers, healthcare staff, district-level managers and provincial managers on parental access to hospitalised children during a pandemic such as COVID-19. It: (i) summarises legal and ethical issues around parental visitation rights; (ii) highlights four guiding principles; (iii) provides 10 practical recommendations to facilitate safe parental access to hospitalised children; (iv) highlights additional considerations if the mother is COVID-19-positive; and (v) provides considerations for fathers. In summary, it is a child's right to have access to his or her parents during hospitalisation, and parents should have access to their hospitalised children; during an infectious disease pandemic such as COVID-19, there is a responsibility to ensure that parental visitation is implemented in a reasonable and safe manner. Separation should only occur in exceptional circumstances, e.g. if adequate in-hospital facilities do not exist to jointly accommodate the parent/caregiver and the newborn/infant/child. Both parents should be allowed access to hospitalised children, under strict infection prevention and control (IPC) measures and with implementation of non-pharmaceutical interventions (NPIs), including handwashing/sanitisation, face masks and physical distancing. Newborns/infants and their parents/caregivers have a reasonably high likelihood of having similar COVID-19 status, and should be managed as a dyad rather than as individuals. Every hospital should provide lodger/boarder facilities for mothers who are COVID-19-positive, COVID-19-negative or persons under investigation (PUI), separately, with stringent IPC measures and NPIs. If facilities are limited, breastfeeding mothers should be prioritised, in the following order: (i) COVID-19-negative; (ii) COVID-19 PUI; and (iii) COVID-19-positive. Breastfeeding, or breastmilk feeding, should be promoted, supported and protected, and skin-to-skin care of newborns with the mother/caregiver (with IPC measures) should be discussed and practised as far as possible. Surgical masks should be provided to all parents/caregivers and replaced daily throughout the hospital stay. Parents should be referred to social services and local community resources to ensure that multidisciplinary support is provided. Hospitals should develop individual-level policies and share these with staff and parents. Additionally, hospitals should ideally track the effect of parental visitation rights on hospital-based COVID-19 outbreaks, the mental health of hospitalised children, and their rate of recovery.

Artesunate compared with quinine for the treatment of severe malaria in adult patients managed in an intensive care unit: A retrospective observational study.

Background: There are limited South African data on the outcomes of patients with severe malaria treated with quinine compared with those treated with artesunate in the intensive care unit (ICU). Objectives: To compare the outcomes of adult patients treated with artesunate against those treated with quinine in the ICU. Primary outcome variables are length of stay (LOS) in the ICU and mortality. Secondary outcomes include the incidence of hypoglycaemic episodes and neurological outcomes. Methods: This was a retrospective cohort study of patients with severe malaria treated at a multidisciplinary ICU with artesunate or quinine from 1 January 2008 to 31 December 2012. Results: Of the 92 patients included in the study, 63 (69.2%) were male. The mean age in the quinine and artesunate groups was 36.2 years and 40.5 years, respectively (p=0.071). Most (98.6%) of the patients with a positive travel history had visited a malaria-endemic region. Of the 53 patients tested for HIV infection, 71.7% tested positive (p=0.520). The average CD4+ cell count of HIV-positive patients treated with quinine was 200 cells/µL compared with 217.17 cells/µL for those treated with artesunate (p=0.875). The mean APACHE II score at admission was 20.85 and 19.62 in the quinine group and artesunate group, respectively (p=0.380). The median LOS was 5 days (range 1 - 27). Mortality was 15.4% in the quinine group and 7.7% in the artesunate group (p=0.246). Conclusion: A statistically insignificant mortality difference was observed in outcomes of the two treatment groups in this retrospective, single-centre cohort study. Contributions of the study: Intravenous artesunate is currently the preferred treatment in the management of patients with severe malaria. However, there are limited local data on the outcomes of artesunate v. quinine therapy for the management of severe malaria in highly monitored clinical environments in non-endemic regions of South Africa.We describe clinical characteristics, management and outcomes of patients with severe malaria treated with quinine and those treated with artesunate in the ICU in a non-endemic region.

The Critical Care Society of Southern Africa Consensus Statement on ICU Triage and Rationing (ConICTri).

Background: In South Africa (SA), intensive care is faced with the challenge of resource scarcity as well as an increasing demand for intensive care unit (ICU) services. ICU services are expensive, and practitioners in low- to middle-income countries experience daily the consequences of limited resources. Critically limited resources necessitate that rationing and triage (prioritisation) decisions are frequently necessary in SA, particularly in the publicly funded health sector. Purpose: The purpose of this consensus statement is to examine key questions that arise when considering the status of ICU resources in SA, and more specifically ICU admission, rationing and triage decisions. The accompanying guideline in this issue is intended to guide frontline triage policy and ensure the best utilisation of intensive care in SA, while maintaining a fair distribution of available resources. Fair and efficient triage is important to ensure the ongoing provision of high-quality care to adult patients referred for intensive care. Recommendations: In response to 14 key questions developed using a modified Delphi technique, 29 recommendations were formulated and graded using an adapted GRADE score. The 14 key questions addressed the status of the provision of ICU services in SA, the degree of resource restriction, the efficiency of resource management, the need for triage, and how triage could be most justly implemented. Important recommendations included the need to formally recognise and accurately quantify the provision of ICU services in SA by national audit; actively seek additional resources from governmental bodies; consider methods to maximise the efficiency of ICU care; evaluate lower level of care alternatives; develop a triage guideline to assist policy-makers and frontline practitioners to implement triage decisions in an efficient and fair way; measure and audit the consequence of triage; and promote research to improve the accuracy and consistency of triage decisions. The consensus document and guideline should be reviewed and revised appropriately within 5 years. Conclusion: In recognition of the absolute need to limit patient access to ICU because of the lack of sufficient intensive care resources in public hospitals, recommendations and a guideline have been developed to guide policy-making and assist frontline triage decision-making in SA. These documents are not a complete plan for quality practice but rather the beginning of a long-term initiative to engage clinicians, the public and administrators in appropriate triage decision-making, and promote systems that will ultimately maximise the efficient and fair use of available ICU resources.

The Critical Care Society of Southern Africa Consensus Guideline on ICU Triage and Rationing (ConICTri).

Background: In South Africa (SA), administrators and intensive care practitioners are faced with the challenge of resource scarcity as well as an increasing demand for intensive care unit (ICU) services. ICU services are expensive, and practitioners in low- to middle-income countries experience the consequences of limited resources daily. Critically limited resources necessitate that rationing and triage (prioritisation) decisions are routinely necessary in SA, particularly in the publicly funded health sector. Purpose: The purpose of this guideline is to utilise the relevant recommendations of the associated consensus meeting document and other internationally accepted principles to develop a guideline to inform frontline triage policy and ensure the best utilisation of adult intensive care in SA, while maintaining the fair distribution of available resources. Recommendations: An overall conceptual framework for the triage process was developed. The components of the framework were developed on the basis that patients should be admitted preferentially when the likely incremental medical benefit derived from ICU admission justifies admission. An estimate of likely resource use should also form part of the triage decision, with those patients requiring relatively less resources to achieve substantial benefit receiving priority for admission. Thus, the triage system should maximise the benefits obtained from ICU resources available for the community. Where possible, practical examples of what the consensus group agreed would be considered appropriate practice under specified South African circumstances were provided, to assist clinicians with practical decision-making. It must be stressed that this guideline is not intended to be prescriptive for individual hospital or regional practice, and hospitals and regions are encouraged to develop specified local guidelines with locally relevant examples. The guideline should be reviewed and revised if appropriate within 5 years. Conclusion: In recognition of the absolute need to limit patient access to ICU because of the lack of sufficient intensive care resources in public hospitals, this guideline has been developed to guide policy-making and assist frontline triage decision-making in SA. This document is not a complete plan for quality practice, but rather a template to support frontline clinicians, guide administrators and inform the public regarding appropriate triage decision-making.

Acute lung injury at Baragwanath ICU. An eight-month audit and call for consensus for other organ failure in the adult respiratory distress syndrome.

To test the expanded definition of acute lung injury (ALI), we prospectively, over a period of 8 months, studied all adult ICU admissions who fitted the definition. Our study consisted of 83 patients with the adult respiratory distress syndrome (ARDS) and 60 with mild to moderate ALI. Sepsis and trauma were the most common diagnoses on admission. The overall mortality rate was 45 percent for ARDS and 38 percent in the other group. Mortality rose significantly with associated other organ failure, the incidence of which was as follows: hepatic, 39 percent; cardiac, 38 percent; hematologic, 22 percent; renal, 21 percent; neurologic, 5 percent. Sepsis syndrome eventually occurred in 73 percent and septic shock in 38 percent of all cases of ALI. We found the expanded definition a useful grading system and consider this definition of ARDS to be currently the best. There are, however, problems with the determination of lung compliance, the effect of inverse ratio ventilation, and the lack of consensus in defining other organ failure.

Ciprofloxacin pharmacokinetic profiles in paediatric sepsis: how much ciprofloxacin is enough?

OBJECTIVE: To determine the pharmacokinetic profile of ciprofloxacin 20 mg/kg per day (10 mg/kg administered intravenously 12 hourly) in paediatric patients with severe sepsis. DESIGN: Open and prospective. SETTING: Tertiary referral multi-disciplinary ICU. PATIENTS: Twenty patients (two groups - group A: 3 months-1 year; group B 1-5 years). INTERVENTIONS: Timed blood samples were taken for pharmacokinetics after the first dose (D(0)), as well as day 2 (D(2)) and then between days 6-8. MEASUREMENTS AND RESULTS: Ciprofloxacin serum levels were measured by high performance liquid chromatography. Demographic and clinical data and all adverse events were noted. Standard pharmacokinetic variables were calculated by non-compartmental methods. Peak concentrations (C(max)) for group A were D(0) 6.1+/-1.2 mg/l, D(2) 9.0+/-1.8 mg/l and D(7) 5.8+/-1.3 mg/l and, for group B, 7.4+/-1.3 mg/l, 7.8+/-1.6 mg/l and 6.4+/-1.3 mg/l, respectively, for the study periods. Concentration 12 h after the start of infusion (C(min)) for all periods were 0.2 mg/l or less. Areas under the curve (AUC, 12 h) were group A: 15.6+/-1.3, 19.2+/-1.63 and 14.1+/-1.4 mg/h per l, and group B: 15.9+/-1.3, 18.0+/-1.7 and 13.2+/-1.26 mg/h per l. One patient presenting with seizures, initially controlled, had another convulsion and a further patient developed seizures whilst on ciprofloxacin. C(max) in these patients were higher than the average C(max). The convulsions of both patients were easily controlled. No other drug-related serious adverse events occurred. No arthropathy was noted. Three patients died of their underlying disease. CONCLUSIONS: There was no accumulation of drug even after 7 days of administration. Our C(max) and AUC were lower than that achieved in a similar adult pharmacokinetic study. To achieve end points of area under the inhibitory curve (AUIC) of 100-150 mg/h per l, 10 mg/kg ciprofloxacin eight hourly would be required for some resistant ICU organisms.

The relationship between blood lactate and survival following the use of adrenaline in the treatment of septic shock.

This prospective observational study evaluates the relationship between adrenaline, lactate and intensive care unit survival in septic shock. Forty patients requiring adrenaline therapy for a first episode of septic shock acquired > 24 hours after admission to the intensive care unit had blood lactate levels measured two-hourly over a 24-hour period. Adrenaline therapy was escalated until target mean arterial pressure was reached. The lactate index was calculated as the ratio of maximum lactate increase to the adrenaline increase. Lactate increased from 2.3 to 2.9 mmol x l(-1) (P = 0.024) and the mean adrenaline increase was 0.14 microg x kg'.minute(-1). Peak lactate correlated with peak adrenaline (rho = 0.34, P = 0.032). Lactate index was the only independent predictor of survival after controlling for age and Acute Physiological and Chronic Health Evaluation II score (odds ratio 1.14, 95% confidence interval 1.03 to 1.26, P = 0.009). A high lactate following adrenaline administration may be a beneficial and appropriate response.

Confirmation of the safety of central venous catheterisation in critically ill infants and children--the Baragwanath experience.

OBJECTIVE: To evaluate, in critically ill children, the safety and effectiveness of routine central venous catheterisations (CVCs) performed by residents from all disciplines. DESIGN: Prospective audit of all CVCs over a 24-month period. SETTING: Multidisciplinary intensive care unit at Baragwanath Hospital, Soweto. PATIENTS: All critically ill patients 12 years of age or younger requiring CVC. All percutaneous sites (subclavian, internal jugular and femoral) were used; these were selected by the attending doctor and not influenced by the audit. RESULTS: There were 272 catheterisation attempts, of which 241 (88.6%) were successful. Patient age and size but not disease severity influenced incidences of both catheterisation failure and minor bleeding. The latter was the commonest early complication, occurring in 63 (23.2%) successful catheterisations. There were 7 major complications-3 pneumothoraces, 2 tachyarrhythmias and 2 major bleeds, all with subclavian vein catheterisation. Catheter-related infections (CRIs) occurred in 85 (51.2%) of 166 lines and catheter-related septicaemia (CRS) in 10 (5.7%) of 175 lines where there were sufficient data for evaluation. No patient or line factor, including duration of insertion, influenced CRI or CRS. In CRI, Staphylococcus epidermidis was the commonest organism. Other common CRI isolates were Enterococcus faecalis, Klebsiella spp. and Candida albicans. Six different organisms were implicated in CRS. CONCLUSIONS: CVC is a safe procedure with a high success rate. The femoral vein is the recommended percutaneous site of choice as it carries no great risk of sepsis and does not expose the patient to the hazard of intrathoracic complications.

Comparison of central venous pressure measurements in the intrathoracic and the intra-abdominal vena cava in critically ill children.

A prospective study was conducted to compare simultaneous intrathoracic and intra-abdominal central venous pressures in 10 critically ill, ventilated paediatric intensive care patients. Central venous pressures were measured using the water column technique over a 6 h study period. There was excellent correlation between intrathoracic and intra-abdominal vena caval pressure measurements (r = 0.974, p < 0.001). The difference between paired measurements did not exceed the limits of agreement (+/- 2SD, -2.36 to 4.42 cm H2O). The mean (SD) difference between readings was small (1.03 +/- 1.69 cmH2O) and was within clinically tolerable limits. These data suggest a clinically useful, close relationship between intra-abdominal and conventional intrathoracic central venous pressure measurement in this group of patients.
