The opioids most commonly used are the lary dilation, wrinkling of the forehead, and opening of highly potent, short-acting phenylpiperidine com- the eyes. Most important, however, awareness or in- pounds (see Chapter 26), such as fentanyl (Sublimaze), complete amnesia may occur. Consequently, additional sufentanil citrate (Sufenta), alfentanil (Alfenta) and doses of the opioids are appropriate when signs of light remifentanil (Ultiva).

SHOCK STATES Shock is defined as inadequate perfusion or oxygen delivery to meet metabolic demand discount desogen 20 without prescription. Specific therapeutic interventions are also dis- cussed in this chapter on page 431 and in Chapter 21 (page 460) buy desogen 20 cheap. Most often due to hemorrhage in the setting of trauma but may also be due to diarrhea, vomiting, or thermal injury. Should be directed toward volume replacement and increased hemoglobin concentration to improve myocardial performance. Cardiogenic: May be due to intrinsic pump failure, dysrhythmia, or compression (ie, tamponade). Should be aimed at optimizing PAOP and increasing contractility, while de- creasing SVR. Septic (Systemic Inflammatory Response Syndrome): Sepsis implies that the shock state is due to an infectious cause. The SIRS has similar hemodynamic characteristics but is not due to an infectious agent (ie, sterile pancreatitis). Septic shock is characterized by prearteriolar shunting, which re- sults in a false increase in SvO2, despite tissue hypoxia. In true septic shock the primary treatment is therapy directed against the infectious cause (ie, drainage of abscess). Neurogenic: Is typically due to high cervical spine injuries or high spinal anesthetics. In the setting of acute trauma with spinal cord injury always assume hemorrhage is the cause of hypotension and treat with fluid resuscitation before using vasoactive agents to raise SVR.
