A few years back while vacationing in Iceland, my son (age 9) started having severe stomach pain. I suspected he was constipated, but he claimed he'd been 'going' ok. After a miserable night in pain I decided he needed to see a doctor.
When I explained our need to the hotel staff, we were put in a taxi and driven to the children's hospital. My son went straight into a large examination room with 6-8 gurnies (all empty at that time). The doctor (who spoke some english) talked with me while two nurses removed all his clothes but placed a folded gown over his crotch. The doctor then examined him and diagnosed him as being constipated and ordered an enema (his first).
The nurses then put the gown on my son and had him lie on his left side. They used a disposable style enema I'd not seen before. It had a squeeze bottle like a Fleet, but larger capacity (I'd guess .5 liter). Instead of a nozzle, it had a 10-12 inch clear tube which snapped onto the bottle. The nurses lubed up the tube, inserted it a couple of inches and started squeezing the bottle. Several times, they stopped squeezing and slid the tube in further until about half was inserted. When the bottle was empty, they withdrew the tube and the waiting began. After about 5 minutes, my son announced he needed to go. The nurses pointed the way to the bathroom and I escorted him out of the examination room and down the corridor to the bathroom, his open back gown flapping in the breeze as he quick-stepped down the hall ahead of me.
With my sons immediate problem eliminated and feeling much better, we returned to the examination room where the doctor gave him a follow up exam and told him he could get dressed. The doctor then told me to go to a pharmacy and buy 2 "Klyx" (not sure of the spelling now), one for tonight and one in the morning. The taxi driver dropped us off at a pharmacy that was a block from the hotel. I handed the note the doctor had given me to the person behind the counter and was given two disposable enemas. These were the just like Fleets here in the US. By mid-morning, he was feeling great and we were able to continue our vacation.
