Burn injury and management in Liberia

Burn care in developing countries remains a challenge. This paper reviews the acute burn care of 21 patients admitted during a 1-year period to a hospital in Liberia. Lack of supplies and education, coupled with the local belief system, reflect on patient management. The study population to falled 21 patients, ranging from 1 to 62 years of age. TBSA burns ranged from 2 to 60 per cent (mean 21 per cent), 61 per cent of patients were grafted. The time between burn and graft varied between 5 and 96 days (mean 29.8). Graft take varied between 40 and 100 per cent (mean 81 per cent). Of the grafted patients 66.6 per cent received blood (average 732 ml). At the time of presentation 61.9 per cent of patients had other illness. The average number of hospital days was 37.9 (range 2–76). The mortality rate was 14.2 per cent. When managing burns in a developing country, adaption of a simple, clearly defined method of treatment, together with education of the caregivers, is suggested. As in the developed world, however, prevention is the critical factor.

Hand burns in children under 5 years of age

In order to evaluate the epidemiology and functional results of hand burns in young children, 92 consecutive patients (126 hand burns) under age 5 years admitted to a Burn Center were reviewed. Scald burns (49 per cent) were most common, followed by flame (34 per cent), contact (14 per cent) and electrical burns (3 per cent). The child was left unattended by an adult in 53 per cent of cases and documented abuse was present in 6 per cent. The mean total body surface area (TBSA) burned was 17 per cent, and 77 patients (85 per cent) had additional burns in other areas (arms 34 per cent, legs 31 per cent, chest 29 per cent and face 27 per cent).

Palmar burns occurred in 24 hands (19 per cent), dorsal in 41 (33 per cent), while both surfaces were burned in 61 (48 per cent). Joints involved included the MP in 96 (76 per cent). PIP in 87 (69 per cent) and DIP in 80 (63 per cent). The depth was superficial partial thickness in 53 (47 per cent), deep partial in 55 (44 per cent), and full thickness in 18 hands (14 per cent); a total of 29 hands were grafted (15 deep partial and 14 full thickness). Escharotomies were required in 12 hands (9 per cent) (9 flame and 3 scald) and partial amputation of digits was required in 3 (2 per cent).

Follow-up was available in 46 hands from 7 to 120 months (mean 39 months). Partial thickness burns (34) healed with normal (32) or near-normal (2) hand function and developmental delay occurred in one patient. Hand function in 12 full thickness burns was normal in 9, decreased in 3 with developmental delay in 2 patients. The number of reoperations required per hand burned after hospital discharge varied with age (2 years and under 1.2 vs. over 2 years 0.6), depth (deep partial 0.4 vs. full thickness 1·6) and surface involved (palmar 1.3 vs. dorsal 0.1 vs. both 1.5), indicating that children under 2 years with full thickness palmar burns are at increased risk of developing burn scar deformities requiring surgical correction. Although 24 total reoperations were required in 25 deep partial and full thickness hand burns, residual burn scar deformities were present in only 2 hands at follow-up (1 boutonniere and I web space contacture).

It is concluded that the overall outcome of hand burns in this age-group is good and developmental delay is rare with proper acute management and prompt surgical correction of burn scar deformities.

Work-related burns: a 6-year retrospective study

During the 6 years from July 1984 to May 1990, 193 patients (30.2 per cent of all patients) were admitted to our regional adult burn centre, for treatment of work-related burn injuries. The median age of patients was 32.5 years (range 18-64 per cent), and 94 per cent were males. Fifty-nine per cent of the patients came from metropolitan Toronto, and 40 per cent from rural Ontario. Most of the patients (97.3 per cent) were referred to the burn centre within 24 h of their injury. The most common aetiology was electrical injury (29.5 per cent), followed by flame (24.4 per cent), contact (10.4 per cent), flash (9.8 per cent), tar and asphalt (9.3 per cent), scald (7.8 per cent), chemical (5.1 per cent), steam (4.7 per cent) and grease (1 per cent). Within the electrical burn group, about one-half were flash burns, one-quarter were clothing fire injuries, and one-quarter were contact injuries. These occupational burns tended to be extensive injuries. The median body surface area (BSA) was 16.5 per cent, with a median full thickness (FT) component of 5.0 per cent. The average length of stay was 20.0 days. Inhalation injury requiring intubation occurred in 14.8 per cent of patients. Sepsis--confirmed by positive blood cultures--developed in 14 per cent of the patients, at an average time of 8.8 days postburn. Staphylococcus aureus was the commonest organism isolated from blood cultures. Pneumonia occurred in 6.3 per cent of patients. A total of 207 surgical procedures was performed on 113 of the 193 patients.(ABSTRACT TRUNCATED AT 250 WORDS)     

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.     

Epidemiological survey of burns treated in Ankara, Turkey and desirable burn-prevention strategies

From 1 January 1979 to 31 December 1993, 1109 patients were admitted to our burn unit located at Hacettepe University. Of the patients, 638 (57.5 per cent) were children (under the age of 16 years). The male to female ratio was 1.4: 1 in children, and was approximately 2.6: 1 for patients over 16 years of age. Of the 638 paediatric patients, 67 (10.5 per cent) sustained electrical burns. The causes of injury in the remaining 571 cases (89.5 per cent) were hot liquids in 379 (66.4 per cent of the non-electrical burns), flame in 190 (33.3 per cent) and contact burns in two (0.3 per cent). Of the scalds, 296 (78.1 per cent of the scalds), 52 (13.7 per cent), 22 (5.8 per cent) and nine (2.4 per cent) were caused by hot water, milk, meal and oil respectively. Of the flame burns, 21 (11.1 per cent) were due to LPG explosions.

Of the 471 adult patients (over 16 years), 159 (33.8 per cent) were injured by electricity. The causes of non-electrical burn injuries were: hot liquid in 25, flame in 274, chemical agents in four, contact in four, and other causes in four. Although our centre is located in Central Anatolia, 41.8 per cent of all patients were referred from the other six regions of Turkey. Of the 1109 inpatients, 645 (58.2 per cent) were injured in Central Anatolia, 279 (25.2 per cent) in the Black Sea Region, 55 (5.0 per cent) in the Mediterranean Region, 18 (1.6 per cent) in the Marmara Region, 34 (3.1 per cent) in the Aegean Region, 52 (4.7 per cent) in Southeastern Anatolia and 26 (2.3 per cent) in Eastern Anatolia. Approximately two-thirds of the patients (419) required one or more surgical interventions, including debridement and grafting, as well as amputation. The most important early complications were acute renal failure (148 patients −13.3 per cent), sepsis (660 patients −59.5 per cent) and gastrointestinal haemorrhage (seven patients −0.6 per cent). The overall mortality rate was 34.4 per cent. The epidemiological pattern of the burns showed that emergency measures should be taken to prevent scalding accidents to children throughout the country, and for electrical burns in adults, particularly those living in the Black Sea Region. In establishing, implementing and directing prevention programmes, regional differences should be taken into consideration.     

Analysis of 105 patients admitted over a 2-year period to a modern burns unit in Saudi Arabia

This is an epidemiological survey of 105 burned patients treated between May 1986 and May 1988 in a modern Burns Unit in Saudi Arabia. Hospitalization time ranged from 1 to 100 days with a mean of 17 days. The mean age of the patients was 9 years. Sixty (57 per cent) of the patients were males and 45 (43 per cent) were females. The main causes of injury were hot liquids (57.7 per cent) and fire (33 per cent). The mean extent of injury was 19 per cent TBSA. Burns covered less than 40 per cent TBSA in 91 out of 105 patients (87 per cent). Deep burns did not exceed 100 units of burned skin in 48 out of 55 patients (87 per cent). Urgent escharotomy was done in 14 patients. Early excision and skin grafting was carried out in 34 patients. Complications included six cases (5.7 per cent) with septicaemia, one (0.9 per cent) with disseminated intravascular coagulopathy, three (2.9 per cent) with amputation and one (0.9 per cent) with stress gastric ulcer. Seven patients discharged themselves against medical advice. Five patients died. The favourable results in this series were attributed mainly to the low severity of burns and partially to the short delay between injury and admission, early surgery and remarkably good facilities. Childhood scalds in this region of the world could possibly be reduced by changing the family habit of having tea at floor level and recommending wide-based tea-pots.     

Chemical burns

This study reports the incidence and nature of chemical burns admitted to a large regional burns unit between 1 January 1981 and 31 December 1987. Of the 3251 patients admitted, 100 had sustained chemical burns; although they only comprised 3.1 per cent of the workload they accounted for 16.5 per cent of all industrial burning accidents. The victims were mainly male adults of working age. Alkaline materials caused 37 per cent of the accidents, 26 per cent attributable to caustic soda; acids caused a further 27 per cent, hydrofluoric acid accounting for half of these. The nature of the chemical was unknown in 13 per cent of the cases; this, together with the fact that workers were often unaware that they were using hazardous substances gives cause for concern. The methods for managing a diverse range of chemical burns are described.     

Exposure-Eusol treatment for burn wounds

Data from 45 adult patients with flame burns covering up to 20 per cent EAB (Group 1), 21-40 per cent (Group 2), and 41-60 per cent (Group 3) are presented. Each group contains 15 patients with 29 females and 16 males, and females had the more extensive burns. All the patients were treated by the exposure method followed by Eusol dressings beginning between post burn days 5 and 7, i.e. as soon as infection was detected or the eschar had started separating. Eusol is an effective antibacterial agent and also assists in slough separation. It appears to be inactive against living tissues and helps obtain healthy granulation tissue. The bed thus created is ideal for grafting. A burn wound up to 40 per cent EAB is suitable for treatment by the exposure-Eusol method. Septicaemia was the common cause of mortality and its incidence was directly related to the extent of injury.     

Topical application of honey in treatment of burns

A total of 104 cases of superficial burn injury were studied to assess the efficiency of honey as a dressing in comparison with silver sulfadiazine gauze dressing. In the 52 patients treated with honey, 91 per cent of wounds were rendered sterile within 7 days. In the 52 patients treated with silver sulfadiazine, 7 per cent showed control of infection within 7 days. Healthy granulation tissue was observed earlier in patients treated with honey (mean 7.4 versus 13.4 days). Of the wounds treated with honey 87 per cent healed within 15 days as against 10 per cent in the control group. Relief of pain, a lower incidence of hypertrophic scar and postburn contracture, low cost and easy availability make honey an ideal dressing in the treatment of burns.     

Epidemiology of industrial burns in Brisbane

A retrospective epidemiological study of industrial burns admitted to the Royal Brisbane Hospital was conducted over a period of 7 years. A total of 182 patients were included in this survey--173 males (95 per cent) and 9 females (5 per cent). The proportion of industrial burns has decreased from 31.5 per cent to 18.5 per cent of total admissions to the burns unit over the past 10 years. Fifty per cent of the burns occurred in males less than 30 years old. The average age was 31 years. Two-thirds of the burns covered less than 10 per cent of the body and 84 per cent covered less than 20 per cent. While scalds were the commonest cause of industrial burns in our study (19.4 per cent), flame burns with clothing ignited caused the most extensive burns. Face and hands were the most common sites involved. Burns to these regions were mainly caused by flame and electrical burns. Eye burns comprised 5.5 per cent of the sample and were due to chemicals, gas explosions and electric flash. Twenty-six patients (14 per cent) suffered respiratory injury. Only one patient out of our series of 182 died. Progress has been made in industrial safety in the past few years but carelessness and human error still take their toll.     

Early enteral nutrition for mass burn injury: the revised egg-rich diet

An aggressive enteral nutritional approach has been employed to support our severely burned patients. The diet is based on a daily intake of 5 eggs/10 kg of body weight, incorporated into milkshakes. Twelve patients with severe burns (age, 24 +/- 4 years; burns, 54 +/- 12 per cent of total body surface area (TBSA] were studied. Enteral feeding was initiated on the day of injury and gradually reached the full formula within 3-7 days. Feeding was carried out either orally or through a nasogastric drip or a combination of both, depending on the patient's condition. Each bottle of milkshake contained 2318 kJ, 29 g protein, 51 g carbohydrate and 28.6 g fat in 250 ml. Each millilitre of the diet contained 9.32 kJ. The protein provided 21 per cent of the total calorie intake, while the fat and carbohydrate provided 42 per cent and 37 per cent respectively. The mean daily intake consisted of protein (5 +/- 1.5 g/kg), carbohydrate (8 +/- 0.75 g/kg) and fat (5 +/- 1 g/kg), providing a daily administration of 378-420 kJ/kg. Plasma lipids remained within normal limits during the 40 days of the diet, while serum protein levels rose to normal levels within the first 3 weeks.     

Clinical characteristics and outcomes of surgical patients with vancomycin-resistant enterococcal infections

The purpose of this study is to determine risk factors associated with mortality in surgical patients with vancomycin-resistant enterococcus (VRE) infections. The hospitalizations of surgical patients with VRE infections from January 1998 to December 2001 were reviewed. Statistical analysis was performed using the Student's t test, chi square, and Fisher's exact test. Thirty-one surgical patients (male:female, 14:17) with a mean age of 51.9 years (range, 21-83 years) developed VRE infection. Infections included bacteremia (12), urinary tract (11), surgical site (seven), and soft tissue (five) infections and intra-abdominal abscess (one). Nine (29.0 per cent) patients received recent outpatient antibiotics and 20 (64.5 per cent) were on steroids. Fifteen (48.4 per cent) patients were treated with intravenous vancomycin before infection. Twelve (38.1 per cent) patients died with a trend toward advanced age (60.7 vs 46.5 years; P = 0.06). The incidence of VRE infection in kidney transplant patients was 1.8 per cent. Six transplant patients (five kidney and one kidney/ pancreas) developed VRE infections with four deaths. Hypertension (P = 0.04), coronary artery disease (P = 0.02), and the need for intra-arterial pressure monitoring (P = 0.04) were associated with mortality. Isolate location, gender, diabetes, renal dysfunction, respiratory disease, liver disease, and serum albumin were not associated with mortality. Kidney transplant patients have a high incidence of VRE infection. Surgical patients with VRE infections have a high mortality rate. Hypertension and coronary artery disease are risk factors for mortality.     

A policy of early excision and grafting in elderly burn patients shortens the hospital stay and improves survival

Early excision and grafting of the burn wound appears to shorten the hospital stay and decrease mortality in children and adults. However, whether an early surgical approach is safe in elderly burn patients has not been resolved. To answer this question we carried out a prospective study of early surgery in 114 consecutive patients over the age of 50 years. Patients were generally operated on between post-burn days 2 and 5. The mean age of the patients was 68 years, with a burn size of 22 per cent, of which 13 per cent was full thickness skin loss. The mean hospital stay of the surviving patients was reduced by 40 per cent compared to national averages (P less than 0.001). The mortality rate for the entire group of patients was 17 per cent, with 2 deaths in the 65 patients with burns less than 20 per cent total body surface area (TBSA). Although the mortality rate for patients with burns greater than 20 per cent TBSA was 35 per cent, this was less than predicted (P less than 0.05). The improvement in survival appeared to be due to a decrease in the incidence of lethal burn wound infections.     

Microbiological aspects of burns at Mount Vernon Hospital, UK

Bacterial infection in 100 burned patients over a 10-month period has been studied. The commonest colonizing organism was Staph. aureus (69 per cent), followed by E. coli (35 per cent). Pseud. aeruginosa accounted for only 28 per cent of isolates. The role of the different bacterial species in burns pathology is discussed. Group G haemolytic streptococci were isolated from 10 per cent of patients and caused graft failure in some cases. Only 3 per cent of patients developed septicaemia and all were due to Staph. aureus. Our approach to management of infection in burns, especially the policy on systemic antimicrobial chemotherapy, is described.     

Acute phase proteins and prognostic inflammatory and nutritional index (PINI) in moderately burned children aged up to 3 years.

In 27 children (12 boys and 15 girls) aged 3 months to 3 years, the plasma levels of albumin, prealbumin, orosomucoid and C-reactive protein (CRP) were determined after burn trauma. The results of these measurements were used to calculate the prognostic inflammatory and nutritional index (PINI). The children were assigned to two groups: a group with burns covering less than 10 per cent of the body surface area (BSA) (minor burns), and those with burns covering 11-20 per cent BSA. The lesions involved were either dermal burns (Class IIB) or full skin thickness burns (Class III). While the group with minor burns showed only a small decrease in albumin and prealbumin levels, the decrease in children with extensive burns was well below values on the first 7 days. On days 2, 5 and 7 after burning, the differences between both groups were statistically significant. Orosomucoid levels were somewhat elevated in the group with extensive burns. This difference, however, was not statistically significant compared with the group with minor burns whose values were slightly below the normal range. The levels of C-reactive protein were statistically significantly increased in children with extensive burns compared with those with burns. The PINI value correlated positively with the burn area given in per cent (for day 5 of follow-up, the regression line equation was y = 9.346 + 1.65 x). These data indicate that there are no pronounced changes in plasma protein levels in the group with minor burns.(ABSTRACT TRUNCATED AT 250 WORDS)     

The last 10 years in a burn centre in Ankara, Turkey: an analysis of 5264 cases

This is a retrospective study analysing 5264 patients treated in the burn centre at Gülhane Military Medical Academy from 1 January 1986 to 31 December 1995. Our burn centre is not only the firs, but one of the best established and supported in Turkey. Our present study has the largest patient group of other previously published studies from Turkey. Of the total patients studied, 4464 patients had minor burns and were treated on an outpatient basis and 800 patients had moderate to major burns. Although our centre is in a military area in Ankara, only 1047 (20 per cent) patients were military personnel and the military-related burn causes comprised only 6 per cent of the total. The remaining 4217 (80 per cent of the total patients) were civilians. Flame injuries were also more frequent in military patients than civilians. Minor burns were most common in the age group 0–10 years old (40 per cent) and moderate to major burns in the age group 21–30 years (54 per cent). Scalds were the main cause of paediatric burns. Male patients were dominant. The overall mortality among inpatients was 18.2 per cent and mean total body surface area (TBSA) was 57.6 per cent in patients who died. 134 patients demonstrated inhalation injury and 82 per cent of these patients died. The epidemiological pattern of our patients is similar to that in other studies from developed countries, although some ethnic causative factors could be found. Our study indicates that emergency measures should be taken to prevent flame injuries at military barracks and industrial workplaces and scalding accidents to children at home and throughout the country.     

An epidemiological study of burn patients hospitalized in Valencia, Spain during 1989.

A retrospective study has been made of the patients hospitalized in the Burn Centre of La Fe Hospital in Valencia (Spain) during 1989. Of the 1825 patients seen during this period, 146 (8 per cent) were admitted to hospital. The mean patient age was 31.42 years, 68.5 per cent of the patients were male; 34.1 per cent were children under the age of 15 years and 15 per cent were over 60 years old. Fire was the most common cause of burns (50 per cent), and produced the most extensive lesions. Electrical current and firm contact with hot surfaces caused deeper burns. Thermal lesions were most frequently produced within the domestic environment. Burns caused by fire affected mainly the head and neck, scalding tended to involve the trunk and electrical current caused injury to the limbs. Half the hospital admissions were discharged within 15 days. Most of the lesions requiring hospital admission occurred during the winter months.
