Background: Methoxyflurane (MF), a volatile anaesthetic agent is known for its analgesic properties in sub anaesthetic concentrations. It has been used as an analgesic agent for short procedures in both adults and children in the prehospital setting and in the emergency department. We conducted a pilot study to investigate the use of MF for burn dressing changes in children. Methods: A prospective case series was conducted in the paediatric burns ward amongst children aged 4–9 years. During burns dressing changes MF was administered using a hand-held patient-controlled device. An investigator monitored vital signs together with pain scores, sedation levels and levels of satisfaction of staff. Results: Twelve patients were enrolled for the study. The majority of the burn wounds were classified as partial-thickness wounds. Methoxyflurane was used as the sole agent for analgesia and sedation for the procedure. No major adverse events were noted. Analgesia and sedation levels were sufficient and appropriate respectively for the majority of the patients during the initial exposure of the wound and the application of the new dressing. However, during the scrubbing of the burn wound analgesia and sedation proved insufficient in four and seven of the patients respectively. Conclusion: In our setting the use of MF for inpatient burn wound dressing changes may be insufficient as a sole agent in the paediatric patient. We suggest it may be used as an adjunct to current practice. Further, larger studies are required to delineate the appropriate role MF can play in the paediatric burns setting.
Background. Pneumonia is one of the leading causes of under-5 death in South Africa and accounts for a substantial burden of paediatric intensive care unit (PICU) admissions. However, little is known about PICU outcomes in HIV-exposed uninfected (HIV-EU) children with pneumonia, despite the growing size of this vulnerable population.Objectives. To determine whether HIV exposure without infection is an independent risk factor for mortality and morbidity in childrenadmitted to PICU with pneumonia.Methods. This retrospective review included all patients with pneumonia admitted to the PICU at Chris Hani Baragwanath AcademicHospital between 1 January 2013 and 31 December 2014. Patients were classified as HIV-unexposed (HIV-U), HIV-EU and HIV-infected.Medical records were reviewed to determine survival to PICU discharge, duration of PICU admission and duration of mechanicalventilation. Survival analysis was used to determine the association between HIV infection/exposure with mortality, and linear regression was used to examine the association with length of stay and duration of mechanical ventilation. This study included 107 patients: 54 were HIV-U; 28 were HIV-EU; 23 HIV-positive; and 2 had an unknown HIV status.Results. Overall, 84% (n=90) survived to PICU discharge, with no difference in survival based on HIV infection or exposure. Both HIV-EUand HIV-U children had significantly shorter PICU admissions and fewer days of mechanical ventilation compared with HIV-infectedchildren (p=0.011 and p=0.004, respectively).Conclusion. HIV-EU children behaved similarly to HIV-U children in terms of mortality, duration of PICU admission and length ofmechanical ventilation. HIV infection was associated with prolonged length of mechanical ventilation and ICU stay but not increasedmortality
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
