Urinary tract infections are common amongst the elderly mainly due to lack of mobility and a poor fluid intake. These infections can increase confusion and it would be worth discussing with your mother's GP the advisability of sending a urine sample to the laboratory to ensure she is being given the necessary and appropriate antibiotics. You should try and encourage her to drink more, especially water.
As far as hygiene is concerned, some wipes you can buy have alcohol in them and this can irritate on already fragile skin. Unperfumed soap and water is the best once any excess faeces has been removed with tissue or a disposable cloth.
You should always deal with the vaginal area and bowel separately when cleaning to avoid transfer of bacteria. Wash the vaginal area from front to back and never apply talcum powder or unprescribed creams.
