Summary

Anisodamine has been widely used in China for its pharmacological effect on improving microcirculation during shock. It has been reported that anisodamine is effective in reducing mortality rate in children with meningitis. however, its effectiveness in patients with septic shock has not been systematically investigated. The aim of the study is to investigate the effectiveness of anisodamine in the treatment of patients with septic shock.

Detailed description

Septic shock is an important contributor of mortality in the intensive care unit (ICU). The crude mortality is reported to be from 30% to 65% (1-5). Although there are significant advances in the management of septic shock in recent decades, the mortality rate was only marginally reduced. For example, the CUB-Réa Network study reported that the mortality rate of septic shock declined from 62.1% in 1993 to 55.9% in 2000 (6). The well-known Surviving Sepsis Campaign has also made every effort to reduce mortality rate of severe sepsis and septic shock. The organization recommended bundled strategies including early goal directed therapy (EGDT) for the management of septic shock (7,8). Although EGDT was once the mainstay therapy of septic shock, its efficacy has been questioned by recent several large randomized controlled trials (9,10). Therefore, the treatment of septic shock is still a global challenge and there is no well-established intervention that can reduce its mortality. Anisodamine is an active agent isolated from a Chinese herb medicine. Both experimental and clinical studies have shown some potential beneficial effects of anisodamine in improving outcomes of shock (11-13). It was reported that anisodamine could reduce the mortality rate of fulminant epidemic meningitis from 66.9% to 12.4% (14). The efficacy of anisodamine might be mediated via the inhibition of thromboxane synthesis, granulocyte and platelet aggregation (15). Although anisodamine has been widely used in the treatment of septic shock in mainland China, there is no solid evidence from well designed clinical trials to support its efficacy. The aim of the study is to investigate the effectiveness of anisodamine in the treatment of critically ill patients with septic shock.

Conditions

• Septic Shock

Interventions

Type	Name	Description
DRUG	anisodamine	Anisodamine will be given first as bolus of 10 mg, followed by 0.1-0.5mg/kg/hr. The adjustment of pump infusion rate is largely at the discretion of treating physician, with the aim of improving microcirculation and limit the side effect to a minimum. For example, if serum lactate continues to elevate, the infusion rate can be increased. Discontinuation on severe side effect or recovery of shock (normalized lactate, weaned from vasopressor) or death.
