The depth of the anal suppository placement depends on the disease being treated. If the treatment is for hemorrhoids, the depth of the suppository placement should be at the second knuckle of the patient’s index finger. If it is the treatment of enteritis, the deeper the suppository needs to be placed, the better, so as to achieve the therapeutic effect of the suppository on the local wound after diffusion. In the process of suppository placement, several points should be noted: 1. plastic gloves should be worn to avoid nail scratches on the anal or rectal mucosa. 2. the head of the suppository should be coated with an appropriate amount of lubricant, including petroleum jelly ointment or sesame oil, soybean oil, etc. 3. another point is to try to lie down for a period of time after placing the suppository, in order to facilitate the dissolution and absorption of the suppository.
