Key result
High-dose insulin therapy can effectively restore hemodynamic stability in patients with poison-induced cardiogenic shock from beta-blocker or calcium channel blocker overdose refractory to conventional treatments.
Why the study?
Does high-dose insulin therapy improve hemodynamic stability in patients with poison-induced cardiogenic shock due to beta-blocker or calcium channel blocker overdose?
Does high-dose insulin therapy improve hemodynamic stability in patients with poison-induced cardiogenic shock due to beta-blocker or calcium channel blocker overdose?
High-dose insulin is an emerging, potentially life-saving therapeutic option for restoring hemodynamic stability in poison-induced cardiogenic shock refractory to conventional treatments.
May support high-dose insulin in refractory cases; leaves open need for prospective trials before adoption.
Poison-induced cardiogenic shock (PICS) as a result of beta-blocker (β-blocker) or calcium channel blocker (CCB) overdose is a common and potentially life-threatening condition. Conventional therapies, including fluid resuscitation, atropine, cardiac pacing, calcium, glucagon, and vasopressors often fail to improve hemodynamic status. High-dose insulin (HDI) is an emerging therapeutic modality for PICS. In this article, we discuss the existing literature and highlight the therapeutic success and potential of HDI. Based on the current literature, which is limited primarily to case series and animal models, the authors conclude that HDI can be effective in restoring hemodynamic stability, and recommend considering its use in patients with PICS that is not responsive to traditional therapies. Future studies should be undertaken to determine the optimal dose and duration of therapy for HDI in PICS.

Woodward et al. (2014) conducted a review in Poison-induced cardiogenic shock (PICS) due to beta-blocker or calcium channel blocker overdose. High-dose insulin (HDI) vs. Conventional therapies was evaluated. High-dose insulin therapy can effectively restore hemodynamic stability in patients with poison-induced cardiogenic shock from beta-blocker or calcium channel blocker overdose refractory to conventional treatments.
