1/70. Abdominal compartment syndrome in patients with burns.Abdominal compartment syndrome (ACS) is a well-recognized perioperative complication that occurs in patients who undergo intra-abdominal operations and who require extensive fluid resuscitation. The classic presentation of this syndrome includes high peak airway pressures; oliguria, despite adequate filling pressures; and intra-abdominal pressures of more than 25 mm Hg. A decompressive laparotomy performed at the bedside can alleviate ACS. If left untreated, sustained intra-abdominal hypertension is often fatal. In the literature, ACS has been described in pediatric patients with burns but not in adult patients with burns. This article describes 3 adults who sustained burns of more than 70% of their body surface areas, who required more than 20 L of crystalloid resuscitation, and who developed ACS during their resuscitation after the burn injury. The mortality rate among these patients was 100%, which confirms the grave consequences of this syndrome. In our institution, intra-abdominal pressure is now routinely measured as part of the burn resuscitation process in an attempt to diagnose and treat this syndrome earlier and more efficaciously. It is recommended that the possibility of ACS be considered when diagnosing any patient with burns who develops high airway pressures, oliguria, or both.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
2/70. Burn due to misuse of an acetylene gas burner: a case report.A rare case of deep penetrating burn injury caused by misuse of a high-pressure acetylene burner is reported. A 35 year old man was admitted with second and third degree burns involving the right arm cubital area and a subcutaneous burn on his right arm caused by a high-pressure acetylene gas flame. Early surgical debridement and secondary skin grafting using a preserved subcutaneous vascular network skin graft (PSVNSG) proved effective in this patient. skin contracture was prevented and function was recovered. The basis of PSVNSG is that the vascular system existing in the graft is used as a permanent vascular system without degeneration. This case shows that, in this kind of burn injury, subcutaneous tissue damage should be suspected and that it is important to perform surgical debridement early after admission.- - - - - - - - - - ranking = 0.4keywords = pressure (Clic here for more details about this article) |
3/70. pulse oximeter-associated toe injuries in a premature neonate: a case report.pulse oximetry is noninvasive and widely used in the intensive care unit and during surgery. Complications associated with the use of pulse oximetry have been reported, including burns, pressure erosion, skin necrosis and digital sensory loss. The causes of these complications may be due to the incompatibilities between the probes and the monitors used from different companies, pressure duration for too long on a single skin site or overheating induced by a short circuit of the probe cable. We report a 940-g premature infant who had severe pulse oximetry-associated injury to the oximetry site. This may have been due to the infant's susceptibility to injury resulting from his critical condition, including low cardiac output, poor peripheral circulation and poor heat dissemination. Our experience shows that, when pulse oximetry is used, especially in critically ill, premature infants, frequent checking of the sensor and the site where the sensor is applied is required to avoid burn injury or pressure erosion of the skin.- - - - - - - - - - ranking = 0.6keywords = pressure (Clic here for more details about this article) |
4/70. Comparison of measures of physiologic stress during treadmill exercise in a patient with 20% lower extremity burn injuries and healthy matched and nonmatched individuals.patients with burn injuries are referred for rehabilitation within days after the injuries to encourage early ambulation and functional training. Many of these patients are hypermetabolic at rest. Metabolic demands of activity are added to the already hypermetabolic state and elevate total energy requirements and some physiologic measures. Reports on the physiologic stress imposed by therapeutic activities for patients with burn injuries are limited to low levels of metabolic demand (< or =2 metabolic equivalents [METS]). The degree of stress imposed by functional activities such as ambulation (3 METS) and stair climbing (5 METS) is not known for adults with burn injuries. The purpose of this study was to report the clinical measures of myocardial and physiologic stress in a patient with 20% lower extremity total body surface area burns during an exercise challenge equivalent to stair climbing. Physiologic measures were assessed before and during a treadmill activity (5 METS) for a 40-year-old obese man 3 weeks after he had lower extremity burn injuries. These measures were compared with mean values for 62 healthy counterparts and 6 healthy subjects matched for age, gender, and fitness level. heart rate, systolic blood pressure, rate pressure product, and the rating of perceived exertion for the patient with burn injuries were higher at baseline and during exercise than the mean values for the 62 healthy individuals and the 6 matched subjects. The steady state exercise values for heart rate, systolic blood pressure, rate pressure product, and rating of perceived exertion at 6 minutes were 189 beats per minute, 190 mm Hg, 3591, and 17, respectively, for the patient with burn injuries and were 111.3 beats per minute, 149 mm Hg, 1680, and 11.7, respectively, for the 6 matched subjects. ventilation during exercise also increased for the patient with burn injuries more than for the matched subjects (3/4 vs 1/4). pain experienced by the patient with burn injuries decreased with activity (9.8 vs 7.3 on a 15-cm scale). Treadmill walking produced near maximal responses for most physiologic measures for this patient who was hypermetabolic at rest. We provided normative data to assist therapists who work with patients with similar burn injuries.- - - - - - - - - - ranking = 0.8keywords = pressure (Clic here for more details about this article) |
5/70. Fulminant pulmonary edema after intramuscular ketamine.PURPOSE: To report an unusual case of pulmonary edema following intramuscular ketamine administration. CLINICAL FEATURES: An eight-year-old, healthy girl presented for dressing of first degree burns on dorsum of hand. Ten minutes after administration of 125 mg ketamine im, she developed laboured breathing, cyanosis, and bilateral crepitations and arterial blood gas analysis showed PaO2 55 mmHg. There was no evidence of upper airway obstruction. On intubating the trachea, pink frothy fluid emerged from the tube. She was diagnosed as a case of neurogenic pulmonary edema. She was managed with positive pressure ventilation with positive end expiratory pressure, morphine and furosemide. With this treatment she showed a favourable recovery. CONCLUSION: ketamine was given im to aid burns dressing in this case because it has distinct advantages above the other anesthetic agents including that of being a good analgesic which is absorbed by im route. Its use led to the development of pulmonary edema.- - - - - - - - - - ranking = 0.4keywords = pressure (Clic here for more details about this article) |
6/70. Nutrition intervention in pediatric patients with thermal injuries who require laparotomy.Increased intra-abdominal pressure is a complication of thermal injuries that is most commonly noted during burn shock or sepsis. Severely elevated intra-abdominal pressure requires surgical treatment by laparotomy to avert cardiac, respiratory, and renal compromise. The purpose of this retrospective study was to examine the manipulation of the nutrition program and outcomes in response to such a procedure. Open laparotomy for increased intra-abdominal pressure was necessary for 6 patients admitted to a pediatric burn facility from March 1993 to April 1999. One patient was excluded from the review because he died 2 days after the burn injury (1 day after the laparotomy) and nutrition intervention was not initiated. Four of the five remaining patients received parenteral nutrition within 48 hours of surgery. One patient did not receive parenteral nutrition because the enteral regimen was at the goal by 5 days after the laparotomy. Trophic enteral feedings were initiated in all 5 patients within 48 hours of the operations. Tube feedings were gradually increased and the parenteral nutrition rate was decreased in accordance with gastrointestinal tolerance (abdominal girth, bowel motility). Enteral nutrition was started before abdomen closure in all of the patients. No mechanical, infectious, or mortality-related complications related to the initiation of enteral nutrition after open laparotomies were noted. Surgical intervention by open laparotomy interrupts the postburn nutrition regimen but does not preclude the safe postoperative delivery and advancement of enteral feedings.- - - - - - - - - - ranking = 0.6keywords = pressure (Clic here for more details about this article) |
7/70. Compartmental syndromes in which the skin is the limiting boundary.Following closed fasciotomy, skin may become the limiting boundary of extremity swelling. The resulting increase in pressure within the limb may threaten its survival. Realizing this potential complications, we reserve closed fasciotomy for those cases in which only moderate swelling is anticipated. Following this procedure the patient is observed closely for evidence that decompression dermotomy is indicated. patients in whom severe swelling is present or anticipated are treated with fasciotomy and primary dermotomy. Wounds are closed by either primary or delayed skin graft. This approach has proven useful in the management of traumatized or vascularly embarrassed limbs in which swelling may compromise extremity viability.- - - - - - - - - - ranking = 0.2keywords = pressure (Clic here for more details about this article) |
8/70. Severe obstructive sleep apnoea secondary to pressure garments used in the treatment of hypertrophic burn scars.Obstructive sleep apnoea (OSA) secondary to pressure garments used to treat hypertrophic scarring of burns has never been reported. The present study describes two children who presented with OSA following introduction of such garments for management of hypertrophic scars following severe facial and upper body burns. Complex sleep polysomnography confirmed severe OSA with desaturations sufficient to result in physiological dysfunction that significantly improved on removal of the garments. As there is little evidence to suggest that the use of such garments alters the end result, the potentially serious side effect of obstructive sleep apnoea should be considered before their use is advised.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
9/70. Effect of facial pressure garments for burn injury in adult patients after orthodontic treatment.Pressure garments are commonly used to prevent and control hypertrophic scar tissue. Complications are unusual, though in children with facial burns, pressure garments may lead to skeletal and dental deformities. Studies in adolescents and adults are sparse. We describe a 24-year-old woman who sustained facial burns. Prior to injury, the patient had undergone premolar extraction in preparation for orthodontic treatment. Her post-burn care consisted of application of a Jobst pressure garment. After 2 months treatment, severe deformation of the dental-alveolar structure was observed. This reports suggests that adults after dental extraction are at a high risk of dental-alveolar deformities from pressure garments and might benefit from the use of occlusal wafers.- - - - - - - - - - ranking = 1.4keywords = pressure (Clic here for more details about this article) |
10/70. Tracheal-innominate artery fistula caused by the endotracheal tube tip: case report and investigation of a fatal complication of prolonged intubation.CASE REPORT: A patient with extensive burns was intubated with an 8.0 mm internal diameter endotracheal tube (ETT) equipped with a subglottic suction port (Mallinckrodt HiLo Evac). The ETT was secured to a left upper molar with wire sutures throughout the hospitalization course to ensure airway stability. On the 40th day of intubation, the patient exsanguinated and died from a tracheo-innominate artery fistula. Postmortem examination revealed a 1 cm lesion of the left anterior tracheal wall at the position of the ETT tip. The prolonged stationary position of the ETT was considered the primary factor responsible for the fistula. Yet tracheo-innominate artery fistula normally is associated with high cuff pressures rather than with the tube tip. The special ETT construction required for the subglottic suction feature was suspected to have increased tube rigidity and may have played a contributory role. methods: The rigidity of the Mallinckrodt HiLo Evac was measured with a mechanical model and compared to 5 other commercially-available ETTs. Rigidity was expressed as the force generated by the ETT tip when the tube curvature was altered by 5 cm and 10 cm of flexion from its resting position. RESULTS: The mean force exerted by the Mallinckrodt HiLo Evac was 10.1 /- 2.8 g at 5 cm of flexion and 17.7 /- 5.1 g at 10 cm of flexion. This was significantly greater than all other ETT brands tested (by one-way analysis of variance and Student-Newman-Kuels test, p < 0.05). CONCLUSION: This case of fatal tracheo-innominate artery fistula formation associated with an ETT tip was unusual because of the extended duration of endotracheal intubation and the complexity of the patient's airway management problems. Our data suggest that the higher rigidity of the HiLo Evac ETT may have contributed to fistula development at the tube tip. However, we do not believe that the higher rigidity of the HiLo Evac ETT necessarily poses any greater risk than other ETTs under normal circumstances, in which the tube tip is not fixed in a stationary position for an extended period.- - - - - - - - - - ranking = 0.2keywords = pressure (Clic here for more details about this article) |
