As for now, I'd like to relate several cases I get at the clinic. Yesterday I finished late as I had to attend to a small boy who got his ***** stuck into his zippers! Blimey, he must have been in a damn great haste to have pulled up the zippers deep into his groin and not realizing it soon enough! So far, all similar cases that I got before were easily reversible. Usually I only had to disengage the zipper's teeth and once removed, I could easily slide the foreskin out the zipper's head. This time it was impossible to apply the simple maneuver as the zipper's head was embedded too deep into the foreskin causing excruciating pain each time I tried to peel it off. After giving some local anesthetic injection, I used a plier to cut the hinge at the zipper's head. If I could cut it off, the problem would be solved. Alas! It was not to be. The hinge that bridge the head together was stronger than I thought and refused to break off even when I applied a mighty force, using both hands and enhanced by gritting teeth! After several vain attempts, I suggested him brought to the hospital, as the child is better off sedated during the procedure and perhaps an emergency circumcision would be best for him.
Another similar accident that needs meticulous removal of the causative object would be the fish-hook injury. The most common part of the body to be pierced are the arms and hands but I have seen hooks sticking through the poor patient's eye-brow or lips!
Now, removing a fish-hook that has lodged into a body part can be a painstaking measure. Due to the unique shape of the hook, you can't simply pull it out. You see, a fishing hook has 2 ends, one bearing a sharp arrow-like figure and the other has an eyelet , where the fishing line is stringed to. If you crudely pull from the eyelet end and forcing the arrow-end through the flesh, it will cause a jagged severance of the soft-tissue and more bleeding will occur. Thus the best technique would be to make the embedded end free, which is usually the arrow head. After locating the head by palpating the affected tissue, make an incision till your blade touches it. Once you've exposed it, use a cutter to cut the hook into two. After removing both ends and cleansing the wound, the incision has to be sutured back.
The worst case scenario would be a combination of the above body-part (zippers blooper) and a fish-hook! In which case, I'd leave it to the surgeon to explore under sedation or GA.
A week ago, when the school hols began, many had chosen to bask on the shores of the east-coast. Unfortunately , it was also the season for the jelly-fishes to come ashore. Thus, I had several patients coming in with painful, excruciating swelling of the legs and hands after being stung by the 'harmless' looking creature. After giving first aid treatment and anti-histamine and steroid injections, I'd pack them off to the nearest hospital for observation as jelly-fish stings can be fatal. So, for those who are ruminating to enjoy the beach, be wary of these creatues.
