FELLOW NURSES

I am concerned about this recent split in my fathers wound. initially the wound was heading nicely with the stitches that were placed. The wound is due to catheters being placed in the groin area. In the last two days I have noticed his wound splitting open. Is this something I should keep dressing and that will heal on its own or does it seem that I should take him back to the doctor to have it stitched up? I’m thinking he needs to go back to the doctor because the wound looks deep enough to me. Any advice is appreciated thank you. Ps he does have an appt next Tuesday but does this look like it requires immediate attention???
