“…However, either antivenom allergic reactions or a subsequent serum sickness did not occur. By authors meaning, this is associated just with gradual and fractionated administration and lowest effective total dose of administered antivenom (Valenta et al, 2014).…”

Envenoming by Crotalid Snake Chinese Moccasin Agkistrodon Acutus Bite – A Case Report

2015

Although the bites caused by snakes from former Agkistrodon family in the areas of occurrence are not rare and even have certain epidemiologic importance, in case of envenoming by Deinagkistrodon acutus the clinical studies and case reports are very sporadic. This case report describes the envenoming of a private snake breeder bitten by young Chinese moccasin Deinagkistrodon acutus to the thumb of his left hand. He sought for a medical help immediately after snakebite. Patient presented with a local oedema on the affected limb, extending up to the half of the forearm. Laboratory examinations showed serious haemostatic disturbance with defibrination syndrome, immeasurably prolonged clotting times and extreme elevation of D-dimers. No other obvious clinical symptoms were present. Fibrinogen and fresh frozen plasma were administered because the antivenom was not available immediately. The specific antivenom was urgently imported 22 hours after the bite and administered at a dose of two vials three times until laboratory haemocoagulation parameters returned back to physiological values.

“…In the Czech Republic we registered 87 victims of exotic snakebites from 1999-2013. Twenty nine cases with systemic envenoming were treated in the ICU with ten of them considered potentially life-threatening (Valenta et al, 2014). All of these articles, however, summarized only reported snakebites.…”

Severe Snakebite Envenoming in Intensive Care

Snakebites by exotic venomous snakes can cause serious or even life-threatening envenoming. In Europe and North America most victims are breeders, with a few snakebites from wild native American rattlesnakes. The envenomed victims may present in organ and/or system failure with muscle paralysis, respiratory failure, circulatory instability, acute kidney injury, severe coagulation disorder, and local disability - compartment syndrome and necrosis. Best managed by close collaboration between clinical toxicology and intensive care, most severe envenomings are managed primarily by intensive care physicians. Due to the low incidence of severe envenoming, the clinical course and correct management of these cases are not intrinsically familiar to most physicians. This review article summarizes the clinical syndromes caused by severe envenoming and the therapeutic options available in the intensive care setting.

“…Venom of most American, African, and Asian Viperidae snakes (subfamily Viperinae and Crotalinae) cause inter alia a hemocoagulation disorder, namely venom-induced consumption coagulopathy (VICC) (1-2). These snakes are popular among breeders in our country (3). During the period from January 1998 to -October 2018, 95 of the 111 bites by exotic snakes were infl icted by Viperidae snakes, and 19 of them suffered from VICC.…”

OBJECTIVE: Viperidae snakes are responsible for 95 % of the bites caused by exotic-bred snakes in our country. Their envenoming may be associated with a severe acute coagulation disorder-venom-induced consumption coagulopathy (VICC). Thus, its early prediction is vital for an adequate therapy including antivenom delivery. MATERIAL AND METHODS: Laboratory coagulation tests of 14 patients suffering from VICC were processed and statistically analyzed to evaluate the importance of individual parameters in the time after the bite. RESULTS: The pathological values of D-dimer (D-dim) and fi brinogen (FBG) were found to be the fi rst indicators of VICC development, with a median time of 4.55 hours since the bite, while median values for prothrombin time and international normalized ratio (PT/INR), activated partial thromboplastin time (APTT), and thrombin time (TT) were 5.9 h, 8.15 h, and 5.5 h, respectively. In the fi rst samples, the values of D-dim were found to be pathologically increased in all 14 patients, while pathological levels of FBG were seen only in 11 cases. PT/ INR and APTT were prolonged in 8 and 6 cases, respectively. CONCLUSION: An increase in D-dim values was found to be the fi rst parameter signaling developing VICC in all analyzed cases (Tab. 2, Ref. 12).

Exotic snake bites in the Czech Republic—Epidemiological and clinical aspects during 15-year period (1999–2013)

Abstract: Bites caused by exotic snakes resulted in serious and life-threatening envenomings in some patients. Early transfer to the Center, antivenom administration, and support of failing organ functions contributed to favorable outcome of victims.
