Twenty-two envenomed patients (39%) received tiger snake or black snake antivenom, and administration within 6 hours of the bite was associated with normalisation of the aPTT. General Description . Proportions are presented with 95% confidence intervals calculated using the Wilson’s procedure with a continuity correction. The median age of patients with definite RBBS bites was 36 years (IQR, 26–58 years). Found: throughout the eastern half of mainland Australia. ‡ Data are median (interquartile range). Eight patients (36%) had immediate hypersensitivity reactions to antivenom, including one case of anaphylaxis. * Data are number (percentage; 95% CI) unless otherwise specified and exclude one patient who was locally envenomed only. 1 The RBBS is an “elapid” snake (member of the family Elapidae) with an average length of 1.25 metres, but may be up to … “Most snake bites occur when people try to kill them ... Just admire them and move on.”. The venom of these snakes consists of myotoxins, neurotoxins and coagulants. Distribution. It also supports one vial of TSAV being enough to bind all venom. Our study showed that one vial of TSAV is likely to be sufficient to bind all venom, with venom undetectable in all tested patients after administration of one vial of antivenom. Conclusion: RBBS envenoming caused local effects, systemic symptoms, anticoagulant coagulopathy and, uncommonly, myotoxicity. Of the remaining 39 (who were all systemically envenomed), 22 did not receive antivenom, 15 of those who received antivenom had post-antivenom samples, and two of those who received antivenom had post-antivenom samples only. One vial of tiger snake or black snake antivenom appears to be sufficient to remove venom and neutralise reversible effects, but hypersensitivity reactions occurred in over a third of patients. Antivenom derived from the tiger snake is used treat bites from these snakes. The most common type of snake found in our area is the red-bellied black snake. Red-bellied black snakes are common in eastern parts of Australia and are known to venture into urban areas. It is an interesting fact, however, that black snakes appear immune to the venom of brown and other venomous snakes… Its bite may cause coagulopathy, neurotoxicity and myolysis. Inland Taipan (Oxyuranus microlepitdotus) Average Size: 6.5 to 8.8 feet (1.9 to 2.68 meters) … * The shaded area indicates the timing of antivenom in those who received it (23, 26 and 30 h after bite). In patients for whom citrate samples were stored, clotting studies were repeated. Red-bellied black snakes are common in eastern parts of Australia and are known to venture into urban areas. Black above along whole body except Sydney … Insufficient data were available for four cases. “Yeah, not walking past there again,” a third local wrote. In those with myotoxicity, antivenom was only administered after the CK was already high, despite an early abnormal aPTT in the majority. The median peak RBBS venom concentration from the 37 systemically envenomed patients with more than one serum sample available was 19 ng/mL (IQR, 12–50 ng/mL; range, 3–360 ng/mL), which did not correlate with clinical severity (, Higher venom concentrations were associated with antivenom administration but not with major clinical effects (. RBBS = red-bellied blacked snake. They are not a particularly aggressive snake but we do see alot of bites in dogs as the dogs will corner the snake and bite them (so of course the snake bites back in defense). More from 7NEWS.com.au In 17 patients who received antivenom and had venom concentration measured, no venom was detected in serum after the first antivenom dose, including nine who were given one vial of tiger snake antivenom. The design of this study has previously been described in detail,14,15 and approval was obtained from 19 human research and ethics committees covering all institutions involved. We describe a cohort of patients from the ASP who had definite RBBS bites. There is no record of any human ever having died from the bite of a Red-Bellied Black Snake. There was poor correlation between peak venom concentrations and the severity of clinical envenoming syndromes, but venom was only detected in the serum of patients with systemic envenoming. However, in contrast to previous studies, it shows that the majority of RBBS envenoming cases develop an anticoagulant coagulopathy characterised by a raised aPTT, and that a small proportion of patients develop significant myotoxicity.
