Major burns undergo tremendous pathophysiological changes in a relatively short period of time.
The immense tissue damage of constitutes a systemic illness. Shock after major thermal injury, is caused by severe hypovolemia, decreased cardiac output (CO), increased pulmonary vascular resis- tance and hemoconcentration. At 24 to 48 hours after successful resuscitation from the initial injury, there is an increased CO, reduced systemic vascular resistance (SVR), a marked increase in meta- bolic rate, and a subsequent systemic inflammatory response syndrome. Severe hemodynamic fluctuations can cause changes in the distribution of, and perhaps response to, drugs commonly used in anesthesia practice. The extent of these changes will depend on the drug, the type and extent of burn and the time elapsed since the injury. This poses a unique clinical challenge to the medical personnel who care for the burns patients.
In major burns, the final pharmacokinetic end products are determined by the balance between increased CO and hepatic clearance vs. decreased serum protein binding and altered lung kinetics.
Pharmacodynamically, alterations in the end organs contribute to the decreased anesthetic effect of many intravenous anesthetics. These include an interaction between endogenous substances the effects of anesthetics at the receptor sites. Drug resistance to muscle relaxants, commonly encountered in major burns, is largely due to the proliferation of immature, fetal-type acetylcholine receptors, with increased mRNA at the neuromuscular junction. Different types of burn injury and recovery stages will determine the clinical manifestation of pain outcome and subsequently, the methods of choice for pain management.
As a member of multidisciplinary burn care team, the roles and potential contributions of anesthesiologists and pain specialists cannot be overemphasized. Their services are truly needed for
