To compare the changes in pHi and intramucosal-arterial CO(2)-gap with invasive haemodynamic and global perfusion measurements during hypovolemic burn shock and to evaluate the sensitivity of these parameters as an early predictor of mortality in patients with extensive burns. ⋯ Gastric tonometry is a poor indicator of splanchnic perfusion in patients with burn shock, even when all precautions are taken to prevent methodological errors. The intramucosal-arterial PCO(2)-gap and pHi do not distinguish survivors from non-survivors. Therefore, gastric tonometry does not seem to improve the ability to anticipate and avert regional anaerobic metabolism during burn shock and its routine use in these patients cannot be recommended.

Burn contractures of the extremities present a clinical challenge. Flexion contractures are more common than extension contractures. ⋯ A number of different methods are available for resurfacing the wound and these are reviewed. An algorithm is presented which permits a simple approach to managing burn scar contracture of the extremities.

Randomized Controlled Trial
A prospective randomized clinical trial to investigate the effect of silicone gel sheeting (Cica-Care) on post-traumatic hypertrophic scar among the Chinese population.
This study aimed to determine the efficacy of silicone gel (Cica-Care) on severe post-traumatic hypertophic scars among the Chinese population. ⋯ This study indicated that silicone gel sheeting (Cica-Care) was effective to reduce thickness, pain, itchiness and pliability of the severe hypertrophic scar among the Chinese population. The moisturization effect of the tough and hard scar might contribute to the reduction of the skin thickness after 6 month's intervention.

The assessment of surface area of the body affected by a burn (TBSA) has long been estimated with manual charts. Initial assessment of burned patients is made frequently by clinicians with limited experience producing significant errors. Paper copies of burn charts are unwieldy, subject to loss and tend towards overestimation. ⋯ This initial pilot study compared figures from 50 paper charts with those from Burn Calculator to determine its accuracy and reproducibility. Previously reported variations in TBSA estimation were confirmed, as was the tendency towards TBSA underestimation resulting from transcription of a three-dimensional clinical situation to a two-dimensional representation. Burn Calculator showed high correlation (r=0.9850; p<0.0001) and reproducibility (R=0.9957) that would simplify assessment and referral plus facilitate data collection, interpretation and research.

This study investigates whether (99m)Tc pyrophosphate (PYP) imaging provides a quantitative non-invasive assessment of the extent of electroporation injury, and of the effect of poloxamer in vivo on electroporated skeletal muscle. ⋯ Behavior of (99m)Tc PYP in electroporated muscle appears to be an indicator of the amount of electroporation injury. Compared to saline, intravenous polaxamer-188 treatment reduced the amount of (99m)Tc PYP uptake. Coupled to results showing poloxamer-188 seals ruptured cellular membranes, lessens the extent of electroporation injury and improves cell viability, (99m)Tc PYP imaging appears to be a useful in vivo monitoring tool for the extent of electroporation injury.
