Anaesthesia for burns in children: a review of procedures practised at Red Cross War Memorial Children's Hospital, Cape Town

Paediatric sedation for imaging is safe and effective in a district general hospital

OBJECTIVE

To devise a safe and effective sedation protocol for imaging paediatric patients in a small district general hospital (DGH).

METHODS

Chloral hydrate, alimemazine and learned best practice were used for imaging 105 children between January 2013 and May 2015. We retrospectively reviewed case notes for this time period to establish rates of successful sedation and adverse events.

RESULTS

Scanning was successful in 100/105 (95%) children. No serious adverse events were reported. Non-serious adverse events occurred in eight cases. 12 patients were discharged more than 4 h after scanning owing to prolonged sedation.

CONCLUSION

This is a safe and effective protocol for delivering sedation for imaging in paediatric patients. We would encourage similar centres to adopt this protocol where resources for i.v. sedation and general anaesthesia are limited.

ADVANCES IN KNOWLEDGE

There are many different sedation protocols in the literature for imaging in paediatric patients, with varying levels of success and adverse event rates. We present here a protocol that offers a high efficacy and safe sedation for imaging in a DGH.

Major burn injury is not associated with acute traumatic coagulopathy

BACKGROUND

The pathophysiology and time course of coagulopathy after major burns are inadequately understood. Our study objectives were to determine whether acute traumatic coagulopathy (ATC) is seen in burn patients at admission and to determine the changes in international normalized ratio (INR), activated partial thromboplastin time (aPTT), platelet count (PLT), and hemoglobin (Hgb) in the first 7 days after injury.

METHODS

We conducted a retrospective study of patients with burn injury of at least 15% total body surface area who presented to the University of North Carolina. Data on patient demographics, injury characteristics, and laboratory data (INR, aPTT, PLT, and Hgb) at admission and within the first 7 days after injury were recorded. We defined ATC as INR of 1.3 or greater, aPTT of 1.5 or greater times the mean normal limit, and normal PLT at admission.

RESULTS

We studied the hematologic profile of 102 patients with burn injury of 15% to 100% total body surface area but did not identify a single patient with ATC at admission. The screening hematologic profile at admission was not influenced by burn severity. In the first 7 days after injury, the INR and aPTT were relatively preserved, while the PLT quickly recovered to baseline after an early decline and the Hgb remained stable at around 10 g/dL; all these changes occurred during the time when the burn patients had received large amounts of fluid resuscitation.

CONCLUSION

The screening hematologic profile of burn patients at admission is normal, and the standard screening assays do not suggest the existence of ATC at admission. While this is a relatively small study, it provides evidence to suggest that ATC is unique to trauma patients.

LEVEL OF EVIDENCE

Prognostic study, level III.

Ketamine in the ED: medical politics versus patient care

The safe and effective use of ketamine for sedation/analgesia by emergency physicians has been validated in the medical literature. Nonetheless, arbitrary restrictions of this medication to anesthesia practitioners have prohibited emergency physician use in some locations. We explore the scientific evidence related to the use of ketamine by emergency physicians for sedation/analgesia, the history of sedation, the operational definitions of conscious sedation and dissociative anesthesia, and the Joint Commission on Accreditation of Healthcare Organizations (JCAHO) related standards. We conclude that ketamine sedation/ analgesia offers many specific advantages for emergency patients and that it is safely administered by emergency physicians in the appropriately monitored setting.
