Resuscitation burn card--a useful tool for burn injury assessment.

It is well recognised that the initial assessment of body surface area affected by a burn is often over estimated in Accident and Emergency Departments. A useful aide-memoir in the acute setting is Wallace's "rule of nines" or using the patients' palmar surface of the hand, which approximates 1% of the total body surface area, as a method of assessment. Unfortunately, as with every system, limitations apply. Factors such as patient size and the interpretation of what is exactly the 'palmar surface' may significantly influence burn size estimations and subsequently fluid resuscitation. Our aim is to develop a simple, quick and easy reproducible method of calculating burn injuries for medical professionals in the acute setting. Worldwide, the dimensions of a credit card are standardized (8.5 cm x 5.3 cm), thus producing a surface area of 45 cm2. We created a resuscitation burn card (RBC) using these exact same proportions, upon which a modified body surface area (BSA) nomogram was printed. Knowing the patient height and weight, we calculated the surface area of the card as percentage of total body surface area (TBSA). On the opposite site of the RBC, a Lund and Browder chart was printed, as well as the Parkland formula and a formula to calculate paediatric burn fluid requirements. The plastic, flexible RBC conformed well to the body contour and was designed for single use. We used the resuscitation burn card in the initial assessment of simulated burns in a Regional Burn Centre and in an Accident and Emergency Department. The information present on the card was found to be clear and straightforward to use. The evaluation of burn extent was found to be more accurately measured than the estimation obtained without the RBC. The resuscitation burn card can be a valuable tool in the hands of less experienced medical professionals for the early assessment and fluid resuscitation of a burn.

Burns inflicted by self or by others--an 11 year snapshot.

INTRODUCTION: In the United Kingdom, the incidence of assault by burning and of self inflicted burns increased significantly over the last decade. This has major implications both for service providers and society as a whole. Our aim was to investigate the differences in patients' characteristics, management and outcome following a burn sustained by either an assault or self immolation. METHODS: Acute admissions to a tertiary Burn Centre were retrospectively reviewed over an 11 year period (1994-2005). Demographic data and information regarding the circumstances surrounding the incident, burn severity, treatment and outcomes of the patients were collected. RESULTS: Over an 11 year period, 1745 patients were admitted to the tertiary Burn Centre. Of this total, 41 patients (mean age 29 years+/-16) sustained burns following an assault, a further 86 patients (mean age of 37 years+/-12) had self inflicted burn injuries; males were preponderant in both groups. In this series, a history of alcohol or substance abuse was present in 25% of both cohorts, 63% of the patients with self inflicted injuries having a previously diagnosed psychiatric disorder. Petrol, accelerants and other flammable liquids were the main agents chosen to inflict injury in both the assault and self inflicted groups. The burn depth and surface area distribution was greater in the self inflicted group compared to those assaulted (29% versus 21%). A difference was also noted in the pattern of distribution of burns between the two groups, as well as between genders although this difference was not significant. Two-thirds (67.4%) of the self immolated patients and 56% of the assaulted group required surgery. The length of hospital stay was similar for both groups, averaging 20 days. The crude mortality for the self inflicted group was 29%, whereas in the assaulted patients, the overall mortality was 4.9%. CONCLUSION: Although the incidence of burns caused either by assault or attempted suicide is low, the affected patients require a multidisciplinary approach. Their management requires significant medical, psychological occupational and social support. Increased awareness and education of those vulnerable individuals maybe of benefit to help prevent self inflicted injuries by burning.

Klippel Trenauney syndrome and reduction mammoplasty.

Klippel Trenauney syndrome is a rare congenital abnormality that includes extremity hypertrophy. We report an unusual case of breast asymmetry due to unilateral chest and limb hypertrophy and describe successful unilateral breast reduction. We highlight the potential problems of surgery within this group and a management approach to minimise complications.

Pseudoaneurysm of the profunda femoris artery due to intertrochanteric fracture of the hip.

Arterial injury caused by hip fracture is a rare event. We report a case of pseudoaneurysm of the profunda femoris artery that presented 4 weeks after correction of an intertrochanteric hip fracture with a dynamic hip screw. The diagnosis was confirmed by Duplex ultrasound scanning, and it was treated by ligation of the profunda femoris artery at the level of the pseudoaneurysm.

Traumatic aneurysm of the basilar artery.

We report a case in which a "false" aneurysm of the basilar artery developed after an assault on a patient resulting in head injuries. Diagnostic imaging and endovascular treatment are described. Formation mechanisms of traumatic intracranial aneurysms are discussed and the literature is reviewed.

Laparoscopic versus open appendicectomy: a prospective evaluation.

A prospective evaluation of laparoscopic surgery for acute appendicitis over a 6-month period is reported. Sixty-five patients with signs and symptoms of appendicitis necessitating surgery were assigned to open (n = 36) or laparoscopic (n = 29) appendicectomy. Thirty-seven patients were female (22 open) and 28 were male (14 open). The median age was 24 (range 14-64) years for open appendicectomy and 18 (range 14-60) years for the laparoscopic procedure. The mean postoperative stay for open operation was 4.8 (range 1-21) days and for the laparoscopic route 2.2 (range 1-11) days (P < 0.05). Inflammation was confirmed histologically in 72 per cent of the open cases and in 74 per cent of the laparoscopic cases (P not significant). The wound infection rate was 11 per cent (n = 4) for open and 4 per cent (n = 1) for laparoscopic appendicectomy (P < 0.05). The median anaesthesia time was 52 (range 15-90) min for open appendicectomy and 48 (range 20-120) min for laparoscopic surgery (P not significant). After open appendicectomy patients had a median of 5 (range 2-12) intramuscular injections of analgesia compared with a median of 1 (range 0-5) in the laparoscopic group (P < 0.05). Two laparoscopic operations were converted to an open procedure. The results suggest that emergency laparoscopic appendicectomy should be explored further as an alternative to open surgery for acute appendicitis.

The epidemiology of head injury in Cantabria.

The epidemiology of head injury was studied in Cantabria, Spain, using a methodological design consisting of a cross-selectional analysis of one year of duration and an additional one year follow-up of all the patients included in the initial sample. The 477 cases identified represent a rate of 91/100,000, with males showing a head injury rate 2.7 times higher that than for females. Sixty per cent of all cases involved traffic accidents, falls accounted for 24% and industrial accidents were the cause in 8%. The annual age-adjusted mortality rate was 19.7/100,000. Over 92% of all deaths occurred prior to hospital admission. The presence of alcohol intoxication was evaluated in 211 cases by determining the osmolar gap. It was found that 51% of all the cases examined presented clear evidence of acute alcohol intoxication.
