A seven-month-old child had a catheter inserted on their head. The needle was pressed on during sleep at night, and there is a concern about whether this situation will have any effects. The answer mentions that the catheter needle is soft and usually slight movement does not cause any major issues, but it is important to check for any backflow of blood or skin breakage, as well as the smoothness of the intravenous infusion. If the infusion is not smooth, it may be necessary to reinsert the needle. It is advised to keep an eye on it but not to worry excessively.
