Yeah, holes really suck. I somewhat recently had a golf-ball sized hole/gash in my right wrist and a 3/4" deep nail-wound in the left wrist from a broken window. If you don't like blood, don't read any further, and respect single-pane windows:
Last September I had a bad experience with a weak window in my apartment (was cracked). I went through it wrist deep like nothing. As the window collapsed my left wrist took a nail-like shard that fell vertically down and into the top of my wrist about 3/4 an inch deep, but only 1/3 inch long, it nailed a semi-good sized artery and it ended up squirting a good 2-feet and onto my face when the shard fell out. I applied immediate pressure with my right hand. I was still bleeding quite a bit, and unknown to me at the moment was my right wrist took a gash on the bottom of it that left a gash you could fit a gold ball into. My tendons took the brunt on the right hand (I didn't go through the window with much force at all (I wasn't intending to break it at all or in any way) and my tendons stopped any critical veins/arteries getting hit in my right hand but unfortunately didn't prevent any damage to my right-hand palm nerves, in particular that meaty chunk below your thumb, though I have started feeling numb pain in it again recently, a sign of the nerves coming back slowly), it had the most damage but was bleeding the least of my two hands). I was testing the window if it was locked, my neighbor had recently been moving and had hit it hard recently with some furniture, when i tested the window for if it was secured my hands barely slipped through the window as it collapsed, but that stuff is SHARP. The same neighbor and his gal came to the rescue, he helped me hold pressure and tourniquet while she called 911. I was bleeding pretty bad and needed to tourniquet my left wrist. It wasn't til I unquieted it with my neighbor did he point out my right wrist's injury. Nothing like seeing the inside center of your wrist (

), it was 1/2 inch deep and clean cut towards the center and as it went towards the outer side and under my thumb the cut got messy and shallow as it hit tendons.
The ambulance rushed me right in, didn't bother to remove any of the tourniquets or clothing I was holding pressure with since they saw the amount of blood loss and knew it was keeping me conscious, they just grabbed gauze and helped me hold pressure on the wrist i wasn't holding. I was really white by the time I got to the hospital and thy started IVs immediately and gave me a tetanus shot also. I told them about the bleeding on my left hand from such a small but deep wound, but in the time since the injury and the time the doc removed my tourniquet and i removed my right hand holding pressure on my left, the artery had sealed itself and the nurse cleaned it and used this medical Superglue to fill and seal the nail wound. My right wrist that luckily escaped with only some sensation-nerve damage to the palm took a total 16 stitches and over an hour for the doctor to stitch. Almost three hours and 2.5 bags of IV fluid into my ER visit the nurse finally asked me if I would like something for the pain. The nurse returned with a smirk on his face as he explained the doc told him to give me a max dose of morphine for my body weight/height ratio (6'4", 280 lbs, hadn't had a thing to eat the entire day

the nurse was my "friend"). The ER was full and busy, so as soon as I stopped taking down the IVs so quickly and was nice n stable in my vitals for 5 hours they released me.
My neighbor ruled when I returned home, he cleaned up the broken glass (secured my window and made it safe for my cat) and cleaned up the blood that was everywhere so my wife at the time didn't have to even see that awful mess. I promptly bought him a 12-pack of his favorite beer. Early the next morning my landlord had the window replaced and all in all the medical insurance came through but I still owe 4-grand for the whole ordeal as my share.
