Use of pneumatic antishock trousers in the management of pediatric pelvic hemorrhage

Fractures of the pelvis in children: a review of the literature

Trauma is the leading cause of death in children. Pelvic ring injuries account for 0.3-4% of all paediatric injuries. The pattern of fractures differs to that seen in adults as it is more ductile. Pelvic ring injuries tend to be more stable as the relatively thick periosteum restricts bony displacement. Intrapelvic viscera are not well protected and can sustain injury in the absence of pelvic fractures. These injuries have traditionally been treated non-operatively. In this paper, we comprehensively review the literature and propose a protocol for treatment taking into consideration associated organ injuries, hemodynamic status of the patient, patient's age, type of fracture and the stability of the pelvic ring.

Pneumatic antisnock garment: state of the art at the turn of the century

The pneumatic antishock garment (PASG) accomplishes in 1999 exactly what Crile postulated that it did in 1901. It increases blood pressure by increasing systemic vascular resistance. No published article counters this fact. The weakness that has become apparent is that this increase in blood pressure can also increase haemorrhage and therefore does not necessarily improve outcome in every patient. Patients in profound shock benefit from the reduction in the vascular space and increased systemic vascular resistance, without excessive additional blood loss. Patients without ongoing haemorrhage benefit from increased blood pressure. Patients with ongoing haemorrhage in the abdomen, retroperitoneal area and pelvis benefit as the rate of blood loss is reduced. The controversy that has been sparked by the device is `what is the end point for resuscitation?'. Two randomized studies using the same method for PASG application and large volume replacement of intravenous (iv) fluids has produced the same outcome. One study has been readily accepted while the other has not. If the PASG is bad for resuscitation then so is large volume iv fluid replacement. One cannot accept scientifically or logically one study without accepting the other. The current indications for PASG are haemorrhage control in the abdomen, retroperitoneum and pelvis, and short-term management of profound shock.

Management of traumatic shock

Trauma is the leading cause of death in the pediatric age group. About 25,000 children die each year and one million children are injured each year in the USA. Aggressive resuscitation determines the outcome of these injured children. The initial hour following the traumatic injury is referred to as the "golden hour" during which we have an opportunity to intervene and improve the outcome. It is not only the first hour which is important but every minute in trauma resuscitation is important. The outcome of traumatic children has a direct correlation to resuscitation. In order to manage traumatic shock there are four basic principles: (a) control of active hemorrhage, (b) assessment of circulatory status, (c) rapid intravascular access, and (d) aggressive fluid resuscitation. Following the four principles of management of traumatic shock and aggressive resuscitation improves the outcome.

A child-oriented emergency medical services system

Although the principles of emergency care may be relatively easy to state, it is their promulgation that is so difficult. The development of EMS-C is the challenge. How do we take these principles of preserving children's lives and translate them into services for everyone who needs them? How do we organize a large, diverse health care system which will be responsive to this group of patients in need? How do we prioritize pediatric emergency care among the many other funding needs, both medical and nonmedical? The answer lies with the initiative and advocacy of each of us as child advocates. Providing all the aforementioned elements of the EMS-C will save children's lives. These are lives which are usually responsive to therapy, uncomplicated by interlocking disease states, and filled with potential for future achievement. The challenge is ours.

Teaching technical skills in pediatrics

Technical skills are an important and difficult part of managing a very sick or injured child. However, technical procedures are more often learned from experience than practice. This article reviews a variety of technical skills and procedures commonly performed in a pediatric emergency department. Each technical procedure can be practiced using live or artificial model for simulation.

Pneumatic anti-shock garment: state of the art 1988

The responses of hypovolemic patients would be expected to be similar to experimental animals that were hypovolemic. Normovolemic patients would be expected to respond as do the normovolemic experimental animals. Hypovolemic patients do not necessarily respond the same as do normovolemic patients or volunteers. The amount of external pressure applied by the device is directly proportional to the amount of tissue pressure increase. Tissue pressure is transmitted to the vessel as reduction transmural pressure, or in change in the size of the vessels and subsequent increase in SVR. Patient response to external pressure varies with the amount of device pressure. The optimal pressure of the PASG is in the range of 60 to 80 torr. Although exceeding this value does not appear to be necessary, it is not harmful in the short term (less than 90 minutes). Using less pressure reduces the SVR and, therefore, the blood pressure response. Keeping the external pressure at approximately 40 torr appears to be ideal for hemorrhage control. Of the more than 300 articles that have appeared in the recent literature addressing the PASG, at least 190 have discussed specific scientific experiments in the animal laboratory, in the human laboratory, or in the clinical environment, in which results gathered addressed how, why, or if the PASG worked. These studies demonstrate that the PASG does, in fact, improve blood pressure, control hemorrhage, improve carotid and upper body blood flow, improve the ability of the prehospital provider to start IV lines, and improve survival (particularly short-term) with few hospital and even fewer prehospital complications. The device produces its blood pressure response by improving preload, increasing SVR, and mobilizing some blood (500 to 1,000 mL) to the upper body compartment above the device. These responses are most probably produced by decreasing the radius of the vessels compressed by the device, decreasing the compartment volume, and differentially affecting the blood flow without and within the device. Hemorrhage is controlled by increasing the external pressure on the vessel by the transmitted increased tissue pressure, reducing the vascular lumen, and reducing the area of the laceration. Short-term survival is improved by decreasing intra-abdominal hemorrhage and improving perfusion (maintaining better oxygenation in the heart-brain-lung circulation.) Long-term survival is improved because the device controls hemorrhage, maintains blood pressure, and allows delivery of the severely injured patient to the trauma center and within the hospital while awaiting an OR, as in the case of a leaking aortic aneurysm.(ABSTRACT TRUNCATED AT 400 WORDS)
