Toxicity - Superglue (cyanoacrylate) used to cover cut skin.

Superglue was used by trauma surgeons in Vietnam to glue the edges of lacerated livers together (ever try to SEW liver?). Works great. It also works perfectly fine in normal skin wounds, and is non-toxic.
The only reason it hasn't been approved by the FDA for this purpose is that the studies would cost millions, and who's going to pay them? Superglue has long since passed off-patent.

I work occasionally at a private research lab which does
experimental surgical research on animals. In dogs, we had a lot of
problem with oozing and infection at sites where arterial catheters
were left in. Now we superglue them and all that problem is gone.

The glue doesn't interfere with healing, and it seals excellently. It is as resistent to abscessing as staples, and seals far better. For
wounds in animals which have been anticoagulated, it's a godsend.
Survival animals which have catheters pulled later suffer no ill
effects, and the wounds heal fine.

Cyanoacrylates for skin closure.

Eaglstein WH, Sullivan T.

Cyanoacrylates (CAs) were not widely adopted for medical use until recently because of lingering concerns regarding the initial tissue toxicities of the short-chain CAs. The medium-chain CAs, primarily butyl-cyanoacrylate, have been widely used in Europe and Canada for several decades and have gone a long way in dispelling any lingering concerns about tissue toxicity. The newer, longer chain CA, octyl-2-cyanoacrylate (2-OCA), now has been approved for multiple uses in the United States and has achieved widespread acceptance by the medical and lay communities. The current authors believe that this is probably only the beginning of the use of 2-OCA and other CAs in cutaneous medicine. This article discusses the use of CAs in their original cutaneous use as glues for the repair of lacerations and incisions and in their more recent use as dressings for the treatment of abrasions and wounds.

Evaluation of an absorbable cyanoacrylate adhesive as a suture line sealant.

Ellman PI, Brett Reece T, Maxey TS, Tache-Leon C, Taylor JL, Spinosa DJ, Pineros-Fernandez AC, Rodeheaver GT, Kern JA.

BACKGROUND: Previous formulations of cyanoacrylate, though very effective, proved to have too high a tissue reactivity to be used internally. A novel cyanoacrylate compound with less tissue reactivity was recently developed. The objective of this study was to assess this novel cyanoacrylate compound for the use as vascular suture line sealant. MATERIALS AND METHODS: Twelve adult female sheep received a 6 mm PTFE interposition graft in each iliac artery, for a total of 24 grafts. Using oxidized cellulose (Surgicel) as a control, two formulations of a new cyanoacrylate compound (named "compound A" and "compound B") were assessed during this trial. Hemostatic efficiency was measured at the time of operation by the assessment of bleeding time and amount of blood loss. Long-term graft patency was assessed angiographically at 4, 6, and 18 months. Tissue reaction at 2 weeks, 1, 6, and 18 months was assessed grossly by vascular surgeons and microscopically by a blinded pathologist. RESULTS: Average time to hemostasis was 37.6, 50.6, and 219 s in group A, group B, and oxidized cellulose control groups, respectively (P<or=0.001 for both compounds versus control). There were no significant differences between groups with regards to graft patency. Histopathology analysis demonstrated mild to moderate tissue reaction at 2 weeks and 1 month in the cyanoacrylate groups compared with controls at 1 month (ANOVA P=0.004). Mild tissue reaction was seen at 6 months and 18 months, with no significant differences between groups (ANOVA P=0.08, 0.62, respectively). CONCLUSIONS: The novel cyanoacrylate compound examined in this study is a highly effective suture line sealant with only mild tissue reactivity and no significant effects on graft patency when studied over an 18 month period.

I can't say for certain if it was a cyanoacrylate, but I do know there is an adhesive available for bonding skin wounds.

I had to check my medicine cabinet to be sure, but Band-Aid "liquid bandages" are cyanoacrylate. I've used it a handful of times on geek wounds and it works great.

No, those are the cuts you get on your fingers when working inside a computer. Stamped metal parts have razor sharp edges.

I once tried to pull a drive bay cover off by sticking my index finger in the index-finger sized hole in it (that's what it was for, right)? I didn't quite pull my finger-tip off - I'd say it only opened up about a third of the circumfrerence, down to the bone. Anyway, that was the first time I used the liquid bandage. You can't get stitches for that - the ER doc/nurse would laugh at you.

Well, wait, now we can determine if it was a true "geek" injury...were you more concerned over the injury to your finger, or that you might have damaged the computer dripping blood onto it?
